check_hparray

False positives. I had a failed drive, this script said all was dandy. I found out I had a bad drive by seeing the yellow indicator when out in the datacenter, then double checked my script and it says it was all good while a drive was indicating it was FAILED when manually running the hpacucli command.

Use check_cciss instead, much more reliable and even detects failed batteries, no need to setup different checks for multiple slots as well.

I`ve made some changes to make this plugin work on CentOS 5 and CentOS 6. I`m checking on DL380 G4, DL360 G5, DL360 G7

What I`ve done is:
Installed ProLiant Support Pack (hpacucli)
* Disabled selinux
recovery >> recover in the script. this is to properly match on status rebuilding.
nagiosuser ALL=(ALL) NOPASSWD:/usr/sbin/hpacucli

use check_cciss.

check_hparray WILL provide false positives!!

Note to the author - thank you, the tool seems to be the basis for other tools. Someone had to make the first tool. You check for OK before you check for failed :-(

Here we have a server with a failed battery and a failed array, yet check_hparray reports to nagios that all is well.


[nagios@alpha plugins]$ ./check_hparray -s 1
RAID OK - (Smart Array P800 in Slot 1 array A logicaldrive 1 (68.3 GB, RAID 1, OK) array B (Failed) logicaldrive 2 (1.2 TB, RAID 1+0, Interim Recovery Mode))
[nagios@alpha plugins]$ echo $?
0

Here is another server with a failed array that reports all is well:


-bash-3.2$ ./check_hparray -s 1
RAID OK - (Smart Array P800 in Slot 1 array A (Failed) logicaldrive 1 (68.3 GB, RAID 1, Interim Recovery Mode) array B logicaldrive 2 (1.2 TB, RAID 1+0, OK))

hpacucli shows a "Failed" disk but plugin says that "RAID: OK" and exits with 0
----- hpacucli output -----

it works sort of. It worked fine on the command line, even as user nagios (so yes, I did setup /etc/sudoers correctly). However, it didn't work from nagios3 nrpe...

Also, having to hard code slots isn't very convinient...... there is a better check.

I tried another one like this, in perl, but that one was broken too.... didn't support slot=0.

The best one, was this one, check_hpccis written by Simone Rosa. That one gave verbose output -v, scanned all arrays... very similiar to this one, yet that one worked out of the box with nagios3.
