Monitoring Disks in PE2800 running windows 2003

[Adam Williams]

Yes I know this is a Linux list, but I couldn't find a Poweredge on 
Windows mailing list, and I figure maybe a few of you out there also 
have poweredge's running Windows.  :)

On my Linux poweredge systems, I have Nagions, NRPE, and 
check_om_storage.pl working beautifully.  However, how can I monitor the 
disk/raid array status on my Poweredge 2800 running Windows 2003 
Server?  I looked at Nagios Exchange and all of the scripts are written 
for Linux, even though there is a windows version of NRPE.  There is a 
dos omreport.exe in the windows package of OMSA.  I tried looking at 
check_megaraid.pl because it can check PERCs through SNMP:

./check_megaraid.pl -H 10.8.2.6 -C public
Megaraid UNKNOWN - could not retrieve snmp data OIDs

running snmpwalk didn't help me much, I spit out the text and searched 
for Disk, Array, PERC, etc but couldn't find a status.

snmpwalk -c public -v 1 10.8.2.6|wc -l
2106

Any suggestions?
