Hi, We've have SCOM setup in our environment to monitor disk space availability. It's been running well for the past year on Windows 2003 server. In recent months, we've added Windows 2008 server to the agent manage list but I noticed through Health Explorer that no disks are showing for Windows 2008 servers. Hardware Availability Rollup is available in Health Explorer but just no disks. Any suggestions what I can do to show disks for 2008 servers? Thanks, Dylan

Hi Dylan Could you confirm if the disks are not listed or if they are listed but have a status of "Not Monitored" (empty green circle)? I assume that they are not listed - in which case they aren't being discovered. So make sure under Administration, Management Packs that you have the windows server 2008 discovery and monitoring management packs imported (there are seperate ones for discovery and monitoring). If they are imported then check that there aren't overrides against the discovery - Authoring, Management Pack objects, object discoveries - Windows Server 2008 Logical Disk. I doubt anyone would have disabled the discovery (and then run remove-disabledmonitoringobject to remove the disks from OpsMgr) but it is worth a check. Also, make sure the logical disk counters are enabled on the servers. A final check is to look at the operationsmanager event log on the windows 2008 servers to see any discovery errors there. Is the agent action account local system? Or did you choose a windows account? Cheers Graham View OpsMgr tips and tricks at http://systemcentersolutions.wordpress.com/

Hi Graham, Thanks for the detail reply. The disks are simply not showing up. I've checked and both management packs for monitor and discovery are imported and enabled. I'm not sure where to run remove-disabledmonitoringobject. Is this to be run on SCOM server or agent? Target server is running on server core. Is there an easy way to check for logical disk counters through cli? I've comb through the event log but did not see any discovery errors. OpsMgr Health Service is running under Local System. Any other suggestions would be much appreciated. Regards, Dylan

Hi Dyl8n, check this out http://www.systemcentercentral.com/BlogDetails/tabid/143/IndexID/84817/Default.aspx Cameron Fuller wrote about a similar problem and hotfixes. Summary: Missing disks on one of your servers? It may be an issue with VSS and disk permissions. Additionally see the hotfixes above. The hotfixes referenced were: http://support.microsoft.com/kb/975928 http://support.microsoft.com/kb/970770 Kobi

The disks are missing for all Windows 2008 servers. On the same server, some disks are with drive letters and some were mount points. Both hotfixes were missing on the servers so I'll look into applying them. Thanks for the suggestion.

Unfortunately the two hotfixes are for Windows 2008 but the target server I'm having trouble with are 2008 R2 so they won't install. I did check and System does have full permission to the disks.

I was able to fix the issue by applying the same management pack on SCOM. Disks are now showing for both 2003 and 2008 servers.
