I have an IBM blade server with RedHat Linux installed.

How can we check to see if we have both disks running as a mirror, or if everything is only running on a single disk? What commands can I use to discover this?

I'm trying to use the cfggen utility to verify this configuration.

./cfggen controller DISPLAY

Please advise on how to find the controller number.

from cfggen docs:

   NAME
   cfggen  -  Configures the Integrated Raid (IR) functionality of the HP
   SAS controllers used in LSI-1068-based HP SAS controllers.

   SYNOPSIS
   cfggen controller# command parameters

          controller#
                    A unique controller number is assigned by the utility
                    to each PCI function found in the system.   Only  PCI
                    functions  on  controller  chips  recognized  by this
                    utility are assigned numbers.




  ./cfggen 
     LSI Logic IR Configuration Utility 2.00.30
     cfggen <controller #> <command> <parameters> ...
     where <controller #> is:
     Number between 0 and 255
0

Assuming that you only have one of them in your machine:

./cfggen 0 [command] [parameters]

Normally numbering should start from 0 as described in your question ...

  • I get the: ./cfggen 0 DISPLAY LSI Logic IR Configuration Utility 2.00.30 cfggen: couldn't open /dev/mptctl! cfggen: make sure the mptctl driver is loaded! – Diana Aug 4 '11 at 21:20
  • Have you ensured the mptctl driver is loaded? What does lsmod tell you? – user62491 Aug 4 '11 at 21:25
  • lsmod | grep -i raid dm_raid45 66509 0 dm_message 6977 1 dm_raid45 dm_region_hash 15681 1 dm_raid45 dm_log 14529 3 dm_mirror,dm_raid45,dm_region_hash dm_mod 62201 5 dm_mirror,dm_multipath,dm_raid45,dm_log dm_mem_cache 9537 1 dm_raid45 – Diana Aug 4 '11 at 21:34
  • from lsmod what I need to think? – Diana Aug 4 '11 at 21:35
