Powershell NRPE NSClient script for HP SmartArray check

I added on to the script felix has created above. This one will return OK with spare drives and return a more specific error to Nagios...

---

$array_config_util = 'C:Program Files (x86)CompaqHpacucliBinhpacucli.exe'

try {
$exec = & $array_config_util 'ctrl all show config'
#Write-Output $exec
}
catch {
Write-Host "Problem checking array status (hint: nagioscheck_smartarray.ps1)"
exit 3
}

# filter results for lines that talk about drives (physicaldrive, logicaldrive)
# and do not end with "OK":
$not_OK = $exec | Where-Object { $_ -like "*drive*" } | Where-Object { $_ -notlike "*OK)"} | Where-Object { $_ -notlike "*OK, spare)"}
if ($not_OK.length -lt 2) {
Write-Host "Array status appears OK"
Write-Host $not_OK
exit 0
}

Write-Host "Array status not OK;" $not_OK
#write-Host $not_OK
exit 2

any news on:
Cannot index into a null array.
At C:Program FilesNSClient++scriptscheck_smartarray.ps1:94 char:77
+ return ($state

?

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:

Looking forward to this plugin but getting some errors: Any thoughts? Running on win2k3 x64. I have a few print here statements trying to locate where the errors are coming from.

Returns OK but status information show:

"Cannot index into a null array."

Looking forward to an updated version!

Same error here.

When run against my server, Nagios is reporting the following under Status Information:

The string starting:
At line:1 char:2
+ -
cordException
+ FullyQualifiedErrorId : TerminatorExpectedAtEndOfString

At least it returns with a Status of 'OK'
