Checking LSI RAID storage status in Linux

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:

# 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.
