[smartmontools-support] cciss support for smartmontools

[Cameron, S. <Ste...@hp...>]

Hi Bruce (et al).

I would like to link to http://smartmontools.sourceforge.net/
from the web page I maintain at http://cciss.sourceforge.net/ =20
if that's alright with you.

I was thinking of putting something like what's below there,
under the cciss utilities section, based on my understanding of =
smartmontools.

And, if anything below doesn't seem right to you, let me know.

      smartmontools -- a couple programs to "control and monitor storage =
systems using the Self-Monitoring, Analysis and Reporting Technology =
System (SMART) built into most modern ATA and SCSI hard disks." (This =
"SMART" has no etymological relationship with the "Smart" in =
"Smartarray", incidentally.)

      Note: this tool will tell you nothing about the status of logical =
drives on your Smartarray, nor is it intended to. It tells you about =
physical disks.

      You will need to get the smartmontools out of CVS rather than =
using the one on the web page. I have seen the one on the web page miss =
drives, while the one currently in CVS finds them. It will not work with =
SATA drives behind a Smartarray controller but seems to work with SCSI =
and SAS drives behind a Smartarray controller.

      To get and build smartmontools from CVS, this worked for me:

      $ cvs -z3 =
-d:pserver:ano...@sm...:/cvsroot/smartmont=
ools co -l sm5
      $ cd sm5
      $ ./autogen.sh
      $ ./configure
      $ make

      To get physical drive information via smartctl, you must specify =
the disk device as well as the controller:

      $ smartctl -d cciss,0 -a /dev/cciss/c0d0

      where "cciss,0" is specifying the first physical disk, and =
"/dev/cciss/c0d0" is specifying the controller.

      It is not obvious how to come up with the physical disk specifier =
that smartctl wants for a given physical disk.

      You can use a for loop to scan for disks, for example:

      $ for x in `seq 0 255`=20
      > do
      > echo $x
      > smartctl -d cciss,$x -a /dev/cciss/c0d0
      > done > output.txt

      After doing that once, you can dig through output.txt to figure =
out which numbers correspond to disks, and thereafter use smartctl with =
just those numbers instead of scanning every number between 0 and 255 =
inclusive, which is a bit slow.=20
