Failed hot spare drive is not detected / HPE ssacli

[crocodileneptune]

Hello Glen,

first of all thanks so much for your work!

I noticed that your check_raid.pl plugin doesn't seem to trigger the warning or critical state in the case of a failed spare drive. In my case, the server used to run on two harddisks in a RAID1 configuration, with another harddisk configured as a hot spare device. When I looked at ILO logs last night, I saw that the harddisk in bay 1 failed and the hot spare in bay 3 was activated some time ago.

I would have expected that the check_raid.pl plugin would trigger some sort of warning if any harddisk fails which is why I now created this bug report. I don't mind the exact state (warning or critical), but a failed device needs to trigger an action which is why I am using the plugin. I read CONTRIBUTING.md and I hope that all relevant details are included in this bug report.

      logicaldrive 1 (558.88 GB, RAID 1, OK)

However, the failed hot spare drive is not detected, even though ssacli notices it:

/sbin/ssacli ctrl slot=0 pd all show status

   physicaldrive 1I:3:2 (port 1I:box 3:bay 2, 600 GB): OK
   physicaldrive 1I:3:3 (port 1I:box 3:bay 3, 600 GB): OK
   physicaldrive 1I:3:1 (port 1I:box 3:bay 1, 0 GB, spare): Failed

Additional environment details:

• Debian 12 Bookworm
• HPE DL360 Gen9 with a P440ar raid controller + BBU

Thanks and best wishes!
