No BBU Information from hpssacli

[jkcgn]

Hi Glen,

i know the bbu-monitoring option is still experimental, but if i use the hpssacli plugin i should at least get an "OK", because hpssacli already contains this information:

root@jk:/usr/lib/nagios/plugins/raidnew# ./check_raid -p hpssacli --bbu-monitoring
OK: hpssacli:[Smart Array P840: Array A(OK)[LUN1:OK]]

root@jk:/usr/lib/nagios/plugins/raidnew# ./check_raid -d -p hpssacli --bbu-monitoring
DEBUG EXEC: /usr/sbin/hpssacli controller all show status at ./check_raid line 474.
DEBUG EXEC: /usr/sbin/hpssacli controller slot=3 logicaldrive all show at ./check_raid line 474.
OK: hpssacli:[Smart Array P840: Array A(OK)[LUN1:OK]]

root@jk:/usr/lib/nagios/plugins/raidnew# /usr/sbin/hpssacli controller all show status
Smart Array P840 in Slot 3
   Controller Status: OK
   Cache Status: OK
   Battery/Capacitor Status: OK


root@jk:/usr/lib/nagios/plugins/raidnew# /usr/sbin/hpssacli controller slot=3 logicaldrive all show
Smart Array P840 in Slot 3
array A
logicaldrive 1 (7.3 TB, RAID 6, OK)

Any Ideas?

thx, Jan

there's just no handling of the BBU information: Plugins/hpacucli.pm

you can start with by providing commands and command outputs, so i can add them to repository and somebody can work on that. (adding to t/data/hpacucli/ dir and sending PR for example)

other than that, cciss plugin which is recommended for such hardware, does not also have bbu support?

[jkcgn]

Yes, i know that cciss it recommended and as cciss_vol_status also supports the hpsa driver and the old ccis block driver, it would be perfect for my hardware.

But cciss can´t retreive any BBU Information from my controller. Thats the reason i would like to use hpssacli instead of cciss.

I also read about the kernel lock problem with hpacucli. But AFAIK hpacucli doesnt support kernel > 2.6 (without a uname26 wrapper script) and it seems that HP moved to hpssacli and the locking problem is gone meanwhile

I´ll upload some more .out files to data the next days, as wanted in CONTRIBUTING.md

[jkcgn]

Ok, forget what i wrote about hpssacli and the resolved kernel locking yesterday! Today i had one, because of monitoring with hpssacli - I'll use cciss_vol_status now. And maybe the BBU Information with cciss_vol_status is missing, because the controller uses CacheVault and BBU, even if this should be supported in fresh versions.

to be able to work on this, you need to provide test commands and data:

Thanks, Glen, great code, we've been using this for years!

So, the magic command that spits out battery status is:

[root@milton ~]# hpssacli controller all show status

Smart Array P440ar in Slot 0 (Embedded)
   Controller Status: OK
   Cache Status: OK
   Battery/Capacitor Status: OK

(Yes, that ends with two blank lines!) Yes, this is the command that's already being run! Yes, it's also reporting the status of the cache-RAM, and hmmm, I don't see that reported "OK" in the output, either (I've used megacli before, I know it does this by default, without --bbu-monitoring.)

What for following da rulez, DEBUG, first with :

[root@milton ~]# /usr/lib64/nagios/plugins/check_raid -d -p hpssacli --bbu-monitoring
check_raid 4.0.6
Visit <https://github.com/glensc/nagios-plugin-check_raid#reporting-bugs> how to report bugs

DEBUG EXEC: /sbin/hpssacli controller all show status at /usr/lib64/nagios/plugins/check_raid line 482.
DEBUG EXEC: /sbin/hpssacli controller slot=0 logicaldrive all show at /usr/lib64/nagios/plugins/check_raid line 482.
OK: hpssacli:[Smart Array P440ar[OK]: Array A(OK)[LUN1:OK], Array B(OK)[LUN2:OK]]

... and without --bbu-monitoring:

root@milton ~]# /usr/lib64/nagios/plugins/check_raid -d -p hpssacli
check_raid 4.0.6
Visit <https://github.com/glensc/nagios-plugin-check_raid#reporting-bugs> how to report bugs

DEBUG EXEC: /sbin/hpssacli controller all show status at /usr/lib64/nagios/plugins/check_raid line 482.
DEBUG EXEC: /sbin/hpssacli controller slot=0 logicaldrive all show at /usr/lib64/nagios/plugins/check_raid line 482.
OK: hpssacli:[Smart Array P440ar[OK]: Array A(OK)[LUN1:OK], Array B(OK)[LUN2:OK]]

Let me know if I can help further / test. Context: CentOS7 on DL560 Gen9; no cciss driver in the kernel :(, otherwise I would use the recommended cciss_vol_status. And, hpssacli-2.40-13.0.x86_64, fresh from the HP repo.
