Preamble The licenses for most software are designed to take away your freedom to share and change it. By contrast, the GNU General Public License is intended to guarantee your freedom to share and change free software--to make sure the software is free for all its users. This General Public License applies to most of the Free Software Foundation's software and to any other program whose authors commit to using it. (Some other Free Software Foundation software is covered by the GNU Lesser General Public License instead.) You can apply it to your programs, too. When we speak of free software, we are referring to freedom, not price. Our General Public Licenses are designed to make sure that you have the freedom to distribute copies of free software (and charge for this service if you wish), that you receive source code or can get it if you want it, that you can change the software or use pieces of it in new free programs; and that you know you can do these things. To protect your rights, we need to make restrictions that forbid anyone to deny you these rights or to ask you to surrender the rights. These restrictions translate to certain responsibilities for you if you distribute copies of the software, or if you modify it. For example, if you distribute copies of such a program, whether gratis or for a fee, you must give the recipients all the rights that you have. You must make sure that they, too, receive or can get the source code. And you must show them these terms so they know their rights. We protect your rights with two steps: (1) copyright the software, and (2) offer you this license which gives you legal permission to copy, distribute and/or modify the software. Also, for each author's protection and ours, we want to make certain that everyone understands that there is no warranty for this free software. If the software is modified by someone else and passed on, we want its recipients to know that what they have is not the original, so that any problems introduced by others will not reflect on the original authors' reputations. Finally, any free program is threatened constantly by software patents. We wish to avoid the danger that redistributors of a free program will individually obtain patent licenses, in effect making the program proprietary. To prevent this, we have made it clear that any patent must be licensed for everyone's free use or not licensed at all. The precise terms and conditions for copying, distribution and modification follow. GNU GENERAL PUBLIC LICENSE TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION 0. This License applies to any program or other work which contains a notice placed by the copyright holder saying it may be distributed under the terms of this General Public License. The "Program", below, refers to any such program or work, and a "work based on the Program" means either the Program or any derivative work under copyright law: that is to say, a work containing the Program or a portion of it, either verbatim or with modifications and/or translated into another language. (Hereinafter, translation is included without limitation in the term "modification".) Each licensee is addressed as "you". Activities other than copying, distribution and modification are not covered by this License; they are outside its scope. The act of running the Program is not restricted, and the output from the Program is covered only if its contents constitute a work based on the Program (independent of having been made by running the Program). Whether that is true depends on what the Program does. 1. You may copy and distribute verbatim copies of the Program's source code as you receive it, in any medium, provided that you conspicuously and appropriately publish on each copy an appropriate copyright notice and disclaimer of warranty; keep intact all the notices that refer to this License and to the absence of any warranty; and give any other recipients of the Program a copy of this License along with the Program. You may charge a fee for the physical act of transferring a copy, and you may at your option offer warranty protection in exchange for a fee. 2. You may modify your copy or copies of the Program or any portion of it, thus forming a work based on the Program, and copy and distribute such modifications or work under the terms of Section 1 above, provided that you also meet all of these conditions: a) You must cause the modified files to carry prominent notices stating that you changed the files and the date of any change. b) You must cause any work that you distribute or publish, that in whole or in part contains or is derived from the Program or any part thereof, to be licensed as a whole at no charge to all third parties under the terms of this License. c) If the modified program normally reads commands interactively when run, you must cause it, when started running for such interactive use in the most ordinary way, to print or display an announcement including an appropriate copyright notice and a notice that there is no warranty (or else, saying that you provide a warranty) and that users may redistribute the program under these conditions, and telling the user how to view a copy of this License. (Exception: if the Program itself is interactive but does not normally print such an announcement, your work based on the Program is not required to print an announcement.) These requirements apply to the modified work as a whole. If identifiable sections of that work are not derived from the Program, and can be reasonably considered independent and separate works in themselves, then this License, and its terms, do not apply to those sections when you distribute them as separate works. But when you distribute the same sections as part of a whole which is a work based on the Program, the distribution of the whole must be on the terms of this License, whose permissions for other licensees extend to the entire whole, and thus to each and every part regardless of who wrote it. Thus, it is not the intent of this section to claim rights or contest your rights to work written entirely by you; rather, the intent is to exercise the right to control the distribution of derivative or collective works based on the Program. In addition, mere aggregation of another work not based on the Program with the Program (or with a work based on the Program) on a volume of a storage or distribution medium does not bring the other work under the scope of this License. 3. You may copy and distribute the Program (or a work based on it, under Section 2) in object code or executable form under the terms of Sections 1 and 2 above provided that you also do one of the following: a) Accompany it with the complete corresponding machine-readable source code, which must be distributed under the terms of Sections 1 and 2 above on a medium customarily used for software interchange; or, b) Accompany it with a written offer, valid for at least three years, to give any third party, for a charge no more than your cost of physically performing source distribution, a complete machine-readable copy of the corresponding source code, to be distributed under the terms of Sections 1 and 2 above on a medium customarily used for software interchange; or, c) Accompany it with the information you received as to the offer to distribute corresponding source code. (This alternative is allowed only for noncommercial distribution and only if you received the program in object code or executable form with such an offer, in accord with Subsection b above.) The source code for a work means the preferred form of the work for making modifications to it. For an executable work, complete source code means all the source code for all modules it contains, plus any associated interface definition files, plus the scripts used to control compilation and installation of the executable. However, as a special exception, the source code distributed need not include anything that is normally distributed (in either source or binary form) with the major components (compiler, kernel, and so on) of the operating system on which the executable runs, unless that component itself accompanies the executable. If distribution of executable or object code is made by offering access to copy from a designated place, then offering equivalent access to copy the source code from the same place counts as distribution of the source code, even though third parties are not compelled to copy the source along with the object code. 4. You may not copy, modify, sublicense, or distribute the Program except as expressly provided under this License. Any attempt otherwise to copy, modify, sublicense or distribute the Program is void, and will automatically terminate your rights under this License. However, parties who have received copies, or rights, from you under this License will not have their licenses terminated so long as such parties remain in full compliance. 5. You are not required to accept this License, since you have not signed it. However, nothing else grants you permission to modify or distribute the Program or its derivative works. These actions are prohibited by law if you do not accept this License. Therefore, by modifying or distributing the Program (or any work based on the Program), you indicate your acceptance of this License to do so, and all its terms and conditions for copying, distributing or modifying the Program or works based on it. 6. Each time you redistribute the Program (or any work based on the Program), the recipient automatically receives a license from the original licensor to copy, distribute or modify the Program subject to these terms and conditions. You may not impose any further restrictions on the recipients' exercise of the rights granted herein. You are not responsible for enforcing compliance by third parties to this License. 7. If, as a consequence of a court judgment or allegation of patent infringement or for any other reason (not limited to patent issues), conditions are imposed on you (whether by court order, agreement or otherwise) that contradict the conditions of this License, they do not excuse you from the conditions of this License. If you cannot distribute so as to satisfy simultaneously your obligations under this License and any other pertinent obligations, then as a consequence you may not distribute the Program at all. For example, if a patent license would not permit royalty-free redistribution of the Program by all those who receive copies directly or indirectly through you, then the only way you could satisfy both it and this License would be to refrain entirely from distribution of the Program. If any portion of this section is held invalid or unenforceable under any particular circumstance, the balance of the section is intended to apply and the section as a whole is intended to apply in other circumstances. It is not the purpose of this section to induce you to infringe any patents or other property right claims or to contest validity of any such claims; this section has the sole purpose of protecting the integrity of the free software distribution system, which is implemented by public license practices. Many people have made generous contributions to the wide range of software distributed through that system in reliance on consistent application of that system; it is up to the author/donor to decide if he or she is willing to distribute software through any other system and a licensee cannot impose that choice. This section is intended to make thoroughly clear what is believed to be a consequence of the rest of this License. 8. If the distribution and/or use of the Program is restricted in certain countries either by patents or by copyrighted interfaces, the original copyright holder who places the Program under this License may add an explicit geographical distribution limitation excluding those countries, so that distribution is permitted only in or among countries not thus excluded. In such case, this License incorporates the limitation as if written in the body of this License. 9. The Free Software Foundation may publish revised and/or new versions of the General Public License from time to time. Such new versions will be similar in spirit to the present version, but may differ in detail to address new problems or concerns. Each version is given a distinguishing version number. If the Program specifies a version number of this License which applies to it and "any later version", you have the option of following the terms and conditions either of that version or of any later version published by the Free Software Foundation. If the Program does not specify a version number of this License, you may choose any version ever published by the Free Software Foundation. 10. If you wish to incorporate parts of the Program into other free programs whose distribution conditions are different, write to the author to ask for permission. For software which is copyrighted by the Free Software Foundation, write to the Free Software Foundation; we sometimes make exceptions for this. Our decision will be guided by the two goals of preserving the free status of all derivatives of our free software and of promoting the sharing and reuse of software generally. NO WARRANTY 11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING, REPAIR OR CORRECTION. 12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH DAMAGES. END OF TERMS AND CONDITIONS How to Apply These Terms to Your New Programs If you develop a new program, and you want it to be of the greatest possible use to the public, the best way to achieve this is to make it free software which everyone can redistribute and change under these terms. To do so, attach the following notices to the program. It is safest to attach them to the start of each source file to most effectively convey the exclusion of warranty; and each file should have at least the "copyright" line and a pointer to where the full notice is found. Copyright (C) This program is free software; you can redistribute it and/or modify it under the terms of the GNU General Public License as published by the Free Software Foundation; either version 2 of the License, or (at your option) any later version. This program is distributed in the hope that it will be useful, but WITHOUT ANY WARRANTY; without even the implied warranty of MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the GNU General Public License for more details. You should have received a copy of the GNU General Public License along with this program; if not, write to the Free Software Foundation, Inc., 51 Franklin Street, Fifth Floor, Boston, MA 02110-1301 USA Also add information on how to contact you by electronic and paper mail. If the program is interactive, make it output a short notice like this when it starts in an interactive mode: Gnomovision version 69, Copyright (C) year name of author Gnomovision comes with ABSOLUTELY NO WARRANTY; for details type `show w'. This is free software, and you are welcome to redistribute it under certain conditions; type `show c' for details. The hypothetical commands `show w' and `show c' should show the appropriate parts of the General Public License. Of course, the commands you use may be called something other than `show w' and `show c'; they could even be mouse-clicks or menu items--whatever suits your program. You should also get your employer (if you work as a programmer) or your school, if any, to sign a "copyright disclaimer" for the program, if necessary. Here is a sample; alter the names: Yoyodyne, Inc., hereby disclaims all copyright interest in the program `Gnomovision' (which makes passes at compilers) written by James Hacker. , 1 April 1989 Ty Coon, President of Vice This General Public License does not permit incorporating your program into proprietary programs. If your program is a subroutine library, you may consider it more useful to permit linking proprietary applications with the library. If this is what you want to do, use the GNU Lesser General Public License instead of this License. cciss_vol_status-1.11/cciss_defs.h0000664000076400007640000000622211465014075014241 00000000000000#ifndef CCISS_DEFS_H #define CCISS_DEFS_H #include /* general boundary definitions */ #define SENSEINFOBYTES 32 /* note that this value may vary between host implementations */ /* Command Status value */ #define CMD_SUCCESS 0x0000 #define CMD_TARGET_STATUS 0x0001 #define CMD_DATA_UNDERRUN 0x0002 #define CMD_DATA_OVERRUN 0x0003 #define CMD_INVALID 0x0004 #define CMD_PROTOCOL_ERR 0x0005 #define CMD_HARDWARE_ERR 0x0006 #define CMD_CONNECTION_LOST 0x0007 #define CMD_ABORTED 0x0008 #define CMD_ABORT_FAILED 0x0009 #define CMD_UNSOLICITED_ABORT 0x000A #define CMD_TIMEOUT 0x000B #define CMD_UNABORTABLE 0x000C /* transfer direction */ #define XFER_NONE 0x00 #define XFER_WRITE 0x01 #define XFER_READ 0x02 #define XFER_RSVD 0x03 /* task attribute */ #define ATTR_UNTAGGED 0x00 #define ATTR_SIMPLE 0x04 #define ATTR_HEADOFQUEUE 0x05 #define ATTR_ORDERED 0x06 #define ATTR_ACA 0x07 /* cdb type */ #define TYPE_CMD 0x00 #define TYPE_MSG 0x01 /* Type defs used in the following structs */ #define BYTE __u8 #define WORD __u16 #define HWORD __u16 #define DWORD __u32 #define CISS_MAX_LUN 1024 #define LEVEL2LUN 1 /* index into Target(x) structure, due to byte swapping */ #define LEVEL3LUN 0 #pragma pack(1) /* Command List Structure */ typedef union _SCSI3Addr_struct { struct { BYTE Dev; BYTE Bus:6; BYTE Mode:2; /* b00 */ } PeripDev; struct { BYTE DevLSB; BYTE DevMSB:6; BYTE Mode:2; /* b01 */ } LogDev; struct { BYTE Dev:5; BYTE Bus:3; BYTE Targ:6; BYTE Mode:2; /* b10 */ } LogUnit; } SCSI3Addr_struct; typedef struct _PhysDevAddr_struct { DWORD TargetId:24; DWORD Bus:6; DWORD Mode:2; SCSI3Addr_struct Target[2]; /* 2 level target device addr */ } PhysDevAddr_struct; typedef struct _LogDevAddr_struct { DWORD VolId:30; DWORD Mode:2; BYTE reserved[4]; } LogDevAddr_struct; typedef union _LUNAddr_struct { BYTE LunAddrBytes[8]; SCSI3Addr_struct SCSI3Lun[4]; PhysDevAddr_struct PhysDev; LogDevAddr_struct LogDev; } LUNAddr_struct; typedef struct _RequestBlock_struct { BYTE CDBLen; struct { BYTE Type:3; BYTE Attribute:3; BYTE Direction:2; } Type; HWORD Timeout; BYTE CDB[16]; } RequestBlock_struct; typedef union _MoreErrInfo_struct{ struct { BYTE Reserved[3]; BYTE Type; DWORD ErrorInfo; } Common_Info; struct{ BYTE Reserved[2]; BYTE offense_size; /* size of offending entry */ BYTE offense_num; /* byte # of offense 0-base */ DWORD offense_value; } Invalid_Cmd; } MoreErrInfo_struct; typedef struct _ErrorInfo_struct { BYTE ScsiStatus; BYTE SenseLen; HWORD CommandStatus; DWORD ResidualCnt; MoreErrInfo_struct MoreErrInfo; BYTE SenseInfo[SENSEINFOBYTES]; } ErrorInfo_struct; #pragma pack() #endif /* CCISS_DEFS_H */ cciss_vol_status-1.11/config.h.in0000664000076400007640000000514012147742127014010 00000000000000/* config.h.in.

Added -x option for exhaustive search Mon Nov 2 04:56:55 CST 2009 Added support for hpsa driver Added support for hpahcisr driver Added support for new controllers: Smart Array P700m Smart Array P212 Smart Array P410 Smart Array P410i Smart Array P411 Smart Array P812 Cache some serial numbers to cut down on redundant i/o when rummaging around trying to figure out what's what. Assume 16 possible storage boxes for SAS based controllers Wed Nov 18 10:18:22 MST 2009 * Fixed bug that if a logical drive had an active spare, and thus was "ok", the exit code was still zero, so it acted as though nothing were wrong, even though the failed drive needed replacing to get back to original good status with spares. * Fixed bug in spare status messages. One message was left out, and so some of the others were wrong, being off-by-one. * Bumped version up to 1.06 2010/05/20 07:12:06 * Change weird "uint" to normal "unsigned int" Thanks to Frank Bergmann for this patch. * Fix strnlen that should have been a strlen. Thanks to Frank Bergmann for noticing this. 2010/10/11 09:41:23 * get rid of typedefs 2010/10/13 07:02:37 * cosmetic whitespace fixes Date: 2010/10/13 07:40:06 * Do not treat hpsa and hpahcisr as if they were MSA1000, but instead treat as cciss devices. This means, use the CCISS_PASSTHRU ioctl, not SG_IO (the drivers for the MSA1000 are qlogic or emulex, and do not have the CCISS_PASSTHRU ioctl, and so must use SG_IO. The difference in power between the SG_IO and CCISS_PASSTHRU is mainly that the CCISS_PASSTHRU allows specifying the 8-byte LUNID, and thus can aim commands at any attached device, whereas SG_IO is aimed by means of which device node you open. However, there are devices (e.g. external controllers, MSA20, etc.) which do not have any exposed device nodes and so are unreachable by SG_IO. By treating hpsa and hpahcisr as cciss, we get access to those devices. * Factor out msa1000_status() * Cleaned up -Wall warnings. * Factor out device type sanity checking code into cciss_device_type_is_correct(), and get rid of the ugly goto for hpsa and hpahcisr cases. * Factor out cciss_logical_drive_status() * Rename the final parameter of cciss_logical_drive_status from 'i' to more sensible 'volume_number' * Make all functions static 2010/10/14 09:36:32 * Zero out controller_lun_list at the beginning init_cciss_to_bmic and num_controllers. init_cciss_to_bmic is called once per controller on the command line to find external controllers, and should be zeroed out each time. 2010/11/05 08:44:13 * Provided local cciss_ioctl.h and cciss_defs.h to aid distros which come with a broken variant of cciss_ioctl.h, and added instructions in INSTALL which explain how to use these fixed headers. * Added note about aclocal-1.10, and corrected note about how to deal with broken cciss_ioctl.h header files. * Clarified that configure failing to #define __user is not the only reason that cciss_ioctl.h might not compile. * Added linux_alternate_makefile.mk to allow sidestepping autoconf problems. 2010/11/19 14:54:44 * Now reports physical drive serial numbers, firmware revision, connector, box and bay information. * Factor out find_bus_target() function * Factor out format_phys_drive_location() * Report S.M.A.R.T. predictive failures Changes since 1.07: 2010/12/02 09:35:54 * Added examples to man page of S.M.A.R.T predictive failure reporting. * make it compile on freebsd * Fix a file descriptor leak Changes since 1.08: 2010/12/03 08:23:26 * Remove unused bogus variable declarations at the end of a function that didn't compile on older gcc versions. (Thanks to Simon Matter) * Print error information if sense bus parameters encounters a target status. * Remove bogus incorrect initialization of controller_lun_list (it's done later down in the code correctly.) * Make it compile with no warnings after "configure CFLAGS=-Wall" Changes since 1.09: * Clean up uninitialized variables detected by valgrind. * Added some new smart array controllers to the list of known controllers * Replace the too specific is_hpsa() and is_hpahcisr() functions with a more generic is_smart_array(). This was preventing -u option from working with the hpsa driver. * Remove inquiry_vendor_model_matches() function which is now no longer used. * Added -W and -Wall flags to gcc in linux_alternate_makefile.mk and fixed up all the warnings that those found. * Add -V (verbose) option which prints out extra information about the controller (board ID, running firmware revision, ROM firmware revision, and number of logical drives). * Make the --verbose option print out more information about the controllers and physical drives. For each controller, the board ID, number of logical drives, currently running firmware revision and ROM firmware revision are printed. For each physical drive, the location, vendor, model, serial number, and firmware revision are printed. * Added .gitignore and cvsignore files * regenerated configure, aclocal.m4, and Makefile.in on RHEL6u2. * Made -p shortcut for --persnickety actualy work. Changes since 1.10 * Added support for new controllers * Now can report status of nonvolatile cache * Misc. code cleanup and refactoring * Do not spin up sleeping spare drives. This is done by using "extended" CISS_REPORT_LUNS to obtain the device type instead of sending inquiries to every device returned by standard CISS_REPORT_LUNS to get the device type. cciss_vol_status-1.11/NEWS0000664000076400007640000000000010572031555012446 00000000000000cciss_vol_status-1.11/INSTALL0000664000076400007640000000464411466051061013017 00000000000000 Just type ./configure make and, as root: make install The "make install" will put cciss_vol_status into /usr/bin, and cciss_vol_status.8.gz into /usr/share/man/man8 To uninstall, as root: make uninstall This will remove /usr/share/man/man8/cciss_vol_status.8.gz and /usr/bin/cciss_voL_status =================================================== Notes that may help with getting things to compile: =================================================== Note: If configure complains about cciss_ioctl.h not compiling, it might be because in the kernel header, there is an attribute "__user" which configure fails to #define out of existence. (cciss_vol_status.c does do this.) You can safely ignore this warning from configure, as the cciss_vol_status code does #define __user precisely because of this. However, it may be the case, esp. if your distro is quite old that cciss_ioctl.h does not compile for another reason (see below). --- Note: If "make" gives you a message such as: WARNING: `aclocal-1.10' is needed, and you do not seem to have it handy on your system. You might have modified some files without having the proper tools for further handling them. Check the `README' file, it often tells you about the needed prerequirements for installing this package. You may also peek at any GNU archive site, in case some other package would contain this missing `aclocal-1.10' program. You can often get around this by doing the following: scameron@zuul:~/test/cciss_vol_status$ aclocal scameron@zuul:~/test/cciss_vol_status$ autoconf scameron@zuul:~/test/cciss_vol_status$ automake scameron@zuul:~/test/cciss_vol_status$ ./configure ... scameron@zuul:~/test/cciss_vol_status$ make Or, you can try to sidestep autoconf and its ornery friends, and use linux_alternate_makefile.mk: make -f linux_alternate_makefile.mk and as root: make -f linux_alternate_makefile.mk install Or, you can dig around looking for aclocal-1.10 --- Note: Some old distros (e.g. debian Sarge) contain a broken version of include/linux/cciss_ioctl.h which doesn't compile at all. Your best bet here is to get a newer version of cciss_ioctl.h which doesn't have that problem. There are recent (circa 2010) cciss header files contained here, cciss_ioctl.h and cciss_defs.h. You can try using these instead of your distro's header files by doing the following: ./configure CFLAGS=-DUSE_LOCAL_CCISS_HEADERS make cciss_vol_status-1.11/Makefile.in0000664000076400007640000005472712147742121014043 00000000000000# Makefile.in generated by automake 1.11.1 from Makefile.am. # @configure_input@ # Copyright (C) 1994, 1995, 1996, 1997, 1998, 1999, 2000, 2001, 2002, # 2003, 2004, 2005, 2006, 2007, 2008, 2009 Free Software Foundation, # Inc. # This Makefile.in is free software; the Free Software Foundation # gives unlimited permission to copy and/or distribute it, # with or without modifications, as long as this notice is preserved. # This program is distributed in the hope that it will be useful, # but WITHOUT ANY WARRANTY, to the extent permitted by law; without # even the implied warranty of MERCHANTABILITY or FITNESS FOR A # PARTICULAR PURPOSE. @SET_MAKE@ VPATH = @srcdir@ pkgdatadir = $(datadir)/@PACKAGE@ pkgincludedir = $(includedir)/@PACKAGE@ pkglibdir = $(libdir)/@PACKAGE@ pkglibexecdir = $(libexecdir)/@PACKAGE@ am__cd = CDPATH="$${ZSH_VERSION+.}$(PATH_SEPARATOR)" && cd install_sh_DATA = $(install_sh) -c -m 644 install_sh_PROGRAM = $(install_sh) -c install_sh_SCRIPT = $(install_sh) -c INSTALL_HEADER = $(INSTALL_DATA) transform = $(program_transform_name) NORMAL_INSTALL = : PRE_INSTALL = : POST_INSTALL = : NORMAL_UNINSTALL = : PRE_UNINSTALL = : POST_UNINSTALL = : bin_PROGRAMS = cciss_vol_status$(EXEEXT) subdir = .

This lets you use wildcards, e.g.: cciss_vol_status /dev/sg* /dev/cciss/c*d0, and the program will not complain as long as all devices which are found to be of the correct type are found to be ok. However, you may wish to explicitly list the devices you expect to be there, and be notified if they are not there (e.g. perhaps a PCI slot has died, and the system has rebooted, so that what was once /dev/cciss/c1d0 is no longer there at all). This option will cause the program to complain about any device node listed which does not appear to be the right device type, or is not openable. .TP \fB\-C, --copyright\fR If stderr is a terminal, Print out a copyright message, and exit. .TP \fB\-q, --quiet\fR This option doesn't do anything. Previously, without this option and if stderr is a terminal, a copyright message precedes the normal program output. Now, the copyright message is only printed via the -C option. .TP \fB\-s\fR Query each physical drive for S.M.A.R.T data and report any drives in "predictive failure" state. .TP \fB\-u, --try-unknown-devices\fR If a device has an unrecognized board ID, normally the program will not attempt to communicate with it. In case you have some Smart Array controller which is newer than this program, the program may not recognize it. This option permits the program to attempt to interrogate the board even if it is unrecognized on the assumption that it is in fact a Smart Array of some kind. .TP \fB\-v, --version\fR Print the version number and exit. .TP \fB\-V, --verbose\fR Print out more information about the controllers and physical drives. For each controller, the board ID, number of logical drives, currently running firmware revision and ROM firmware revision are printed. For each physical drive, the location, vendor, model, serial number, and firmware revision are printed. .TP \fB\-x, --exhaustive\fR Deprecated. Previously, it "exhaustively" searched for logical drives, as, under some circumstances some logical drives might otherwise be missed. This option no longer does anything, as the algorithm for finding logical drives was changed to obviate the need for it. .SH DEVICE .PP The DEVICE argument indicates which RAID controller is to be queried. Note, that it indicates which RAID controller, not which logical drive. .PP For the cciss driver, the "d0" nodes matching "/dev/cciss/c*d0" are the nodes which correspond to the RAID controllers. (See note 1, below.) It is not necessary to invoke cciss_vol_status on each logical drive individually, though if you do this, each time it will report the status of ALL logical drives on the controller. .PP For the hpsa driver, or for fibre attached MSA1000 family devices, or for the hpahcisr sotware RAID driver which emulates Smart Arrays, the RAID controller is accessed via the scsi generic driver, and the device nodes will match "/dev/sg*" Some variants of the "lsscsi" tool will easily identify which device node corresponds to the RAID controller. Some variants may only report the SCSI nexus (controller/bus/target/lun tuple.) Some distros may not have the lsscsi tool. .PP .br Executing the following query to the /sys filesystem and correlating this with the contents of /proc/scsi/scsi or output of lsscsi can help in finding the right /dev/sg node to use with cciss_vol_status: .PP .nf .LD wumpus:/home/scameron # ls -l /sys/class/scsi_generic/* lrwxrwxrwx 1 root root 0 2009-11-18 12:31 /sys/class/scsi_generic/sg0 -> ../../devices/pci0000:00/0000:00:02.0/0000:02:00.0/0000:03:03.0/host0/target0:0:0/0:0:0:0/scsi_generic/sg0 lrwxrwxrwx 1 root root 0 2009-11-18 12:31 /sys/class/scsi_generic/sg1 -> ../../devices/pci0000:00/0000:00:1f.1/host2/target2:0:0/2:0:0:0/scsi_generic/sg1 lrwxrwxrwx 1 root root 0 2009-11-19 07:47 /sys/class/scsi_generic/sg2 -> ../../devices/pci0000:00/0000:00:05.0/0000:0e:00.0/host4/target4:3:0/4:3:0:0/scsi_generic/sg2 wumpus:/home/scameron # cat /proc/scsi/scsi Attached devices: Host: scsi0 Channel: 00 Id: 00 Lun: 00 Vendor: COMPAQ Model: BD03685A24 Rev: HPB6 Type: Direct-Access ANSI SCSI revision: 03 Host: scsi2 Channel: 00 Id: 00 Lun: 00 Vendor: SAMSUNG Model: CD-ROM SC-148A Rev: B408 Type: CD-ROM ANSI SCSI revision: 05 Host: scsi4 Channel: 03 Id: 00 Lun: 00 Vendor: HP Model: P800 Rev: 6.82 Type: RAID ANSI SCSI revision: 00 wumpus:/home/scameron # lsscsi [0:0:0:0] disk COMPAQ BD03685A24 HPB6 /dev/sda [2:0:0:0] cd/dvd SAMSUNG CD-ROM SC-148A B408 /dev/sr0 [4:3:0:0] storage HP P800 6.82 - .DE .fi .PP From the above you can see that /dev/sg2 corresponds to SCSI nexus 4:3:0:0, which corresponds to the HP P800 RAID controller listed in /proc/scsi/scsi. .SH EXAMPLE .nf .LD [root@somehost]# cciss_vol_status -q /dev/cciss/c*d0 /dev/cciss/c0d0: (Smart Array P800) RAID 0 Volume 0 status: OK. /dev/cciss/c0d0: (Smart Array P800) RAID 0 Volume 1 status: OK. /dev/cciss/c0d0: (Smart Array P800) RAID 1 Volume 2 status: OK. /dev/cciss/c0d0: (Smart Array P800) RAID 5 Volume 4 status: OK. /dev/cciss/c0d0: (Smart Array P800) RAID 5 Volume 5 status: OK. /dev/cciss/c0d0: (Smart Array P800) Enclosure MSA60 (S/N: USP6340B3F) on Bus 2, Physical Port 1E status: Power Supply Unit failed /dev/cciss/c1d0: (Smart Array P800) RAID 5 Volume 0 status: OK. /dev/cciss/c1d0: (Smart Array P800) RAID 5 Volume 1 status: OK. /dev/cciss/c1d0: (Smart Array P800) RAID 5 Volume 2 status: OK. /dev/cciss/c1d0: (Smart Array P800) RAID 5 Volume 3 status: OK. /dev/cciss/c1d0: (Smart Array P800) RAID 5 Volume 4 status: OK. /dev/cciss/c1d0: (Smart Array P800) RAID 5 Volume 5 status: OK. /dev/cciss/c1d0: (Smart Array P800) RAID 5 Volume 6 status: OK. /dev/cciss/c1d0: (Smart Array P800) RAID 5 Volume 7 status: OK.

There is NO warranty; not even for MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. .SH "SEE ALSO" http://cciss.sourceforge.net .SH note 1 The /dev/cciss/c*d0 device nodes of the cciss driver do double duty. They serve as an access point to both the RAID controllers, and to the first logical drive of each RAID controller. Notice that a /dev/cciss/c*d0 node will be present for each controller even if no logical drives are configured on that controller. It might be cleaner if the driver had a special device node just for the controller, instead of making these device nodes do double duty. It has been like that since the 2.2 linux kernel timeframe. At that time, device major and minor nodes were statically allocated at compile time, and were in short supply. Changing this behavior at this point would break lots of userland programs. .FE cciss_vol_status-1.11/aclocal.m40000664000076400007640000010346312147742120013625 00000000000000# generated automatically by aclocal 1.11.1 -*- Autoconf -*- # Copyright (C) 1996, 1997, 1998, 1999, 2000, 2001, 2002, 2003, 2004, # 2005, 2006, 2007, 2008, 2009 Free Software Foundation, Inc. # This file is free software; the Free Software Foundation # gives unlimited permission to copy and/or distribute it, # with or without modifications, as long as this notice is preserved. # This program is distributed in the hope that it will be useful, # but WITHOUT ANY WARRANTY, to the extent permitted by law; without # even the implied warranty of MERCHANTABILITY or FITNESS FOR A # PARTICULAR PURPOSE. m4_ifndef([AC_AUTOCONF_VERSION], [m4_copy([m4_PACKAGE_VERSION], [AC_AUTOCONF_VERSION])])dnl m4_if(m4_defn([AC_AUTOCONF_VERSION]), [2.63],, [m4_warning([this file was generated for autoconf 2.63.

In an in-source build this is usually # harmless because $srcdir is `.', but things will broke when you # start a VPATH build or use an absolute $srcdir. # # So we could use something similar to $top_srcdir/$ac_aux_dir/missing, # iff we strip the leading $srcdir from $ac_aux_dir. That would be: # am_aux_dir='\$(top_srcdir)/'`expr "$ac_aux_dir" : "$srcdir//*\(.*\)"` # and then we would define $MISSING as # MISSING="\${SHELL} $am_aux_dir/missing" # This will work as long as MISSING is not called from configure, because # unfortunately $(top_srcdir) has no meaning in configure. # However there are other variables, like CC, which are often used in # configure, and could therefore not use this "fixed" $ac_aux_dir. # # Another solution, used here, is to always expand $ac_aux_dir to an # absolute PATH.

Generally, SCSI things, like reads, writes, inquiries, etc. use the 8-byte LUN as reported by REPORT_LOGICAL_LUNS. And BMIC commands use another way, I'll call it "the BMIC way." There can be controllers behind controllers. For instance, you might have a 6400 HBA cabled to a MSA500 external box. The 6400's a smartarray PCI board connected via SCSI cables to the MSA500. The MSA500 has a Smartarray RAID controller inside it. The controller in the MSA500 will have an 8-byte LUN address, as does the 6400. The 6400's LUN will be all zeroes. The MSA500's will be something else, as reported by REPORT_PHYSICAL_LUNS, and identified as an MSA500 by an inquiry to that LUN. Further complications can come up with SSP, in that there may be logical drives addressable the "BMIC way", which are not addressable via any 8-byte LUN from the host. (more of a SAN thing, but anyhow...) So, an address of a logical drive "the BMIC way" consists of the LUN of the controller which that logical drive is on, plus a "BMIC drive number" which gets crammed into the BMIC CDB. So, how do you figure out the BMIC address which corresponds to a given 8-byte lun address? For specific controllers, there may be some shortcuts. However, to do it in a general way, without having to be aware of nasty controller details nobody should be forced to be aware of, the following algorithm is implemented. Do a report logical LUNs to get a list of LUNs. (On some controllers which support a large number of logical drives, this may take awhile to complete.) Get inquiry page 0x83 from each LUN which supports it, and remember this data. Do a report physical LUNs, and an inquiry to each to find any external RAID controllers (e.g. MSA500). For each controller (LUN 0x0000000000000000 plus any external controllers found in previous step) do: BMIC 0x10, identify logical drive. This returns, among other things, same data as inquiry page 0x83, above. Match up the data returned by BMIC 0x10 with Inquiry page 0x83. init_cciss_to_bmic implements this algorithm. You might wonder why instead, we don't just have for example vendor specific inquiry pages accessible via the 8-byte LUN which report the same things as are accessible via the old "BMIC way", esp, e.g. SENSE_LOGICAL_DRIVE_STATUS. I wonder the same thing myself. This function has the side effect of filling out controller_lun_list[] and num_controllers. ***************************************8***************************/ static int init_cciss_to_bmic(char *file, int fd) { /* Create a mapping between 8-byte luns from REPORT_LOGICAL_LUNS and 8-byte controller LUN address + BMIC drive number tuples.

Let us hope that IBM fixes the xlc bug, and also adds support for this kind of constant expression.
