Great plugin!

Thank you!

I just had to modify a couple of lines:

I added
# nagios -epn
just after the interpreter declaration so Nagios won’t try to use its embedded perl interpreter (which exits with some compile errors)

I also had to move “Unbound” from line 895 to line 891.
For some reason my AX4-5 reports the Hot Spare disk as Unbound making the script report 0 HS available and triggering a warning.
