SNMP logical drive data wrong

coec — Thu, 09 Dec 2010 06:10:44 GMT

I've found that the following query returns incorrect information:
snmpwalk -v 2c -c PUBLIC localhost 1.3.6.1.4.1.232.3.2.3.1.1.10
SNMPv2-SMI::enterprises.232.3.2.3.1.1.10.1.1 = Hex-STRING: 00 01 02 03 04 05 06 07
SNMPv2-SMI::enterprises.232.3.2.3.1.1.10.1.2 = Hex-STRING: 00 01 02 03 04 05 06 07

I have two logical drives defined: One is RAID5 with 4 drives, the other is RAID10 with 4 drives. The data returned in response to the query indicates that all physical drives are in both logical drives.

The server in question is a HP Proliant DL380 G5 with the latest PSP.

I'm sorry, when I said 'with the latest PSP' I probably wasn't clear. I mean: the latest Proliant Support Pack _is_ installed.

rpm -q hpacucli hp-health hp-snmp-agents
hpacucli-8.60-8.0

HI Coec,

thanks for detailed information.

I see predictive failure on two of your HDDs and associated customer advisory. So, you may need to take it seriously as at this point we are not sure whether it's due to HDD firmware or actual firmware.

about the SNMP returning the incorrect info,
I didn't find much info but last software has fixed the similar issue I had.

I see latest PSP Version: 8.64 (22 Oct 2010) is available.

I will check and let you know if find more information about SNMP issue.

thanks,
Aftab

I only see v8.60 for RHEL5, which is what I'm using.
