I try to monitor the RAID-status on my HP ProLiant DL380 G5 with hpacucli 9.20. But, it's acting rather weird. Most of the time, it will return:

root@SERVER:~# hpacucli ctrl all show
Error: No controllers detected.

But now and then it actually works as intended:

root@SERVER:~# hpacucli ctrl all show
Smart Array P800 in Slot 4                (sn: PXXXXXXXXX)

I ran a few tests, and found that it fails around 90-95% of the time when i executed the command every other second over a period of 20 minutes (600 executions).

Does anyone have a clue? What can be the cause of this weird behaviour?

Technical info:

  • OS: Ubuntu Server 12.04 LTS 64-bit
  • Kernel: Linux xen 3.2.0-29-generic #46-Ubuntu SMP
  • Smart Array FW version: 7.24
  • Controller: HP Smart Array P800
  • hpacucli version: 9.20.9.0

If you're just looking to monitor RAID status, executing hpacucli on its own as a health-check isn't the right way. I could understand it failing, too. I can't repeat the same behavior on my RHEL and CentOS servers, though. strace may be your friend in this case, since the failures are easily reproduced.

You want to use the hp-snmp-agents and hp-health packages for real continuous monitoring (which provides email and SNMP alerts).

Ubuntu is a bit of a compromise with HP servers, as the value-add tools aren't as well-developed as they are for more Enterprise operating systems.

Please see my notes at: Disk/RAID Monitoring for HP Proliant Servers and Ubuntu 12.04

It seems like you'll need some combination of the software delivered by the SDR repository detailed at: http://communitylinux.org/node/446#comment-866

  • Thanks for an extensive answer! What I want to do, is to monitor if any disks is in any other state than OK (and that is working perfectly, when hpacucli works..) I know that Ubuntu is not as well supported as RHEL, but it should work nevertheless... Any other I'll compare results from strace though. – LarsErikP Apr 04 '13 at 11:03
