I also had trouble with this script on our servers. In particular, it returned a false "OK" status when I pulled a drive out of the array. I tried debugging it for a bit, but ended up getting frustrated and just rewrote it much shorter:

# NAME: check_smartarray.ps1

# ABOUT: Checks the output of HP's Array Configuration Utility for Smart Array
# RAID controllers, and tries to detect any problems with array status.
#
# This was inspired by Christophe Robert's "Powershell NRPE NSClient
# script for HP SmartArray check", found here:
# http://exchange.nagios.org/directory/Plugins/Hardware/Server-Hardware/HP-(Compaq)/Powershell-NRPE-NSClient-script-for-HP-SmartArray-check/details
# That one seemed a bit complicated, so I shortened it.
