Hi! Graham, Thank you very much - chkdsk worked. appreciate your help.

HI! All, One of the physical server (win 2k3 r2), we have the OS drive and an additional 1 terra drive attached from the SAN. The health explorer says "logical disk availability" is critical for the SAN volume. I can access the san volume and it shows up on my computer and also under disk management. There is totally no issue access the volume. I dont want to disable this drives monitoring. Iam not sure opsmgr 2007 reports it as unavailable? I reset the health - and it turns to green - but within miutes it turns back to critical. Please appreciate some help on this. Thank you venn

Hi Venn I'm actually on holiday at the moment so only intermittently on the forums and have no access to an OpsMgr system. I'm back July 13th so if I get some time can take a look at the other issues then (as I'll need to look at a system to be able to answer them!).
