NAME
cciss_vol_status - show status of logical drives attached to HP Smartarray controllers
SYNOPSIS
cciss_vol_status [OPTION] [DEVICE]...
DESCRIPTION
Shows the status of logical drives configured on HP Smartarray controllers.
OPTIONS
-p, --persnickety
Without this option, device nodes which can't be opened, or which are not found to
be of the correct device type are silently ignored. 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.
-C, --copyright
If stderr is a terminal, Print out a copyright message, and exit.
-q, --quiet
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.
-s Query each physical drive for S.M.A.R.T data and report any drives in "predictive
failure" state.
-u, --try-unknown-devices
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.
-v, --version
Print the version number and exit.
-V, --verbose
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.
-x, --exhaustive
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.
DEVICE
The DEVICE argument indicates which RAID controller is to be queried. Note, that it
indicates which RAID controller, not which logical drive.
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.
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.
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:
wumpus:/home/scameron # ls -l /sys/class/scsi_generic/*

DIAGNOSTICS
Normally, a logical drive in good working order should report a status of "OK." Possible
status values are:
"OK." (0) - The logical drive is in good working order.
"FAILED." (1) - The logical drive has failed, and no i/o to it is poosible.
Additionally, failed drives will be identified by connector, box and bay, as well
as vendor, model, serial number, and firmware revision.
"Using interim recovery mode." (3) - One or more drives has failed,
but not so many that the logical drive can no longer operate. The failed drives
should be replaced as soon as possible.
"Ready for recovery operation." (4) - Failed drive(s) have been
replaced, and the controller is about to begin rebuilding redundant parity data.
"Currently recovering." (5) - Failed drive(s) have been replaced,
and the controller is currently rebuilding redundant parity information.
"Wrong physical drive was replaced." (6) - A drive has failed, and
another (working) drive was replaced.
"A physical drive is not properly connected." (7) - There is some
cabling or backplane problem in the drive enclosure.
(From fwspecwww.doc, see cpqarray project on sourceforge.net):
Note: If the unit_status value is 6 (Wrong physical drive was replaced) or 7 (A
physical drive is not properly connected), the unit_status of all other configured
logical drives will be marked as 1 (Logical drive failed). This is to force the
user to correct the problem and to insure that once the problem is corrected, the
data will not have been corrupted by any user action.
"Hardware is overheating." (8) - Hardware is too hot.
"Hardware was overheated." (9) - At some point in the past,
the hardware got too hot.
"Currently expannding." (10) - The controller is currently in the
process of expanding a logical drive.
"Not yet available." (11) - The logical drive is not yet finished
being configured.
"Queued for expansion." (12) - The logical drive will be expended
when the controller is able to begin working on it.
Additionally, the following messages may appear regarding spare drive status:
"At least one spare drive designated"
"At least one spare drive activated and currently rebuilding"
"At least one activated on-line spare drive is completely rebuilt on this logical drive"
"At least one spare drive has failed"
"At least one spare drive activated"
"At least one spare drive remains available"
Active spares will be identified by connector, box and bay, as well
as by vendor, model, serial number, and firmware revision.
For each logical drive, the total number of failed physical drives, if more than zero,
will be reported as:
"Total of n failed physical drives detected on this logical drive."
with "n" replaced by the actual number, of course.
"Replacement" drives -- newly inserted drives that replace a previously failed drive but
are not yet finished rebuilding -- are also identified by connector, box and bay, as well
as by vendor, model, serial number, and firmware revision.
If the -s option is specified, each physical drive will be queried for S.M.A.R.T data, any
any drives in predictive failure state will be reported, identified by connector, box and
bay, as well as vendor, model, serial number, and firmware revision.
Additionally failure conditions of disk enclosure fans, power supplies, and temperature
are reported as follows:
"Fan failed"
"Temperature problem"
"Door alert"
"Power Supply Unit failed"
FILES
/dev/cciss/c*d0 (Smart Array PCI controllers using the cciss driver)
/dev/sg* (Fibre attached MSA1000 controllers and Smart Array controllers using the hpsa
driver or hpahcisr software RAID driver.)
EXIT CODES
0 - All configured logical drives queried have status of "OK."
1 - One or more configured logical drives queried have status other than "OK."
BUGS
MSA500 G1 logical drive numbers may not be reported correctly.
I've seen enclosure serial numbers contain garbage.
Some Smart Arrays support more than 128 physical drives on a single RAID controller.
cciss_vol_status does not.

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.
