Flying blind is no fun and many hardware manufacturers are notoriously bad at providing info tools form their hardware for Linux. If you have an LSI-chipped RAID controller, this may come in handy. The `storcli`utility replaces the MegaCLI utility and is provided by Broadcom.
You can get `storcli`here:
(For Debian/Ubuntu distributions, you may need to install `alien` to convert the .rpm to .deb.)
The following script is what I use and it works for me:
#!/bin/bash # # Check LSI RAID storage status # # This will trigger on the output NOT being "Optl" (Optimal). This works for me, # your mileage may vary. One problem in using more "verbose output" from the # storcli64 binary is that it always (?) outputs some sort of legend with all # the various status types explained, so it always contains the text "Degraded" # for example. This minor script will simply search for what we want, which is # a RAID in optimal state, and if NOT found, perform a full status scan and send # it as an e-mail message to wherever it needs to be sent. # # Joaquim Homrighausen <email@example.com> # 2020-12-15 # STATUS=`/usr/local/bin/storcli64 /c0 /v0 show nolog |egrep "RAID6 Optl"`; EGREP=$? if [ "$EGREP" -ne 0 ] then TOfirstname.lastname@example.org STATUS=`/usr/local/bin/storcli64 /c0 show`; /usr/sbin/sendmail -i $TO <<MAIL_END From: email@example.com To: $TO Subject: RAID WARNING @ `hostname` $STATUS MAIL_END fi
