Remount drive letters of SAN disks by script

[ehudkaldor]

Hi all,
Is there a way to automatically mount drive letters (on SAN disks) after they loose it (by some unchanging identifier like GUID or path)? I tried using diskpart, but since windows changes the volume enumeration every time it looses and reacquires the devices, it cannot guaranty that the same volume will have the same index next time around.

I have had this problem in the past (and occasionally still have it when making changes to the SAN environment). Run DMDIAG to enumerate your Dynamic disks on the SAN, and the problem should go away

Question - if you don't mind, not trying to hijack thread.
Itsp, does this happen when the disks are only dynamic? I have clusters on SAN disk; since MS Clustering doesn't support dynamic disks, the disks are basic. Have you seen the same issue with basic disks.

The disks are basic. I never said it's dynamic.

ok... I never said you stated they were dynamic. I was asking istp1965.

In my case Kenny the drives are dynamic. I had spoken to MS support about this and they sent me a hotfix (922529)which has been recently superceded by another one (don't remember the number). I haven't applied since the DMDIAG solution was working for me until recently (I noticed that the problem crops up everytime I make changes to the SAN environment)

Thanks for the info...
