Great work!

Very nice plugin. I can only recommend.
Thanks for your work!

I had to make a small fix to work on my system:
(v1.15)
on line 296:
from: if [ -x $hpssacli ]; then
to: if [ -e $hpssacli ]; then
since -x tests FILE exists and execute (or search) permission is granted
But I guess in my case execute is not granted at test time.
