We have a two node 2003 cluster. When we move a group from Node2 to Node1
the physical disk resource does not get a drive letter. If we go into disk
administrator on Node1 and assign the drive letter 'K' then the resource will
come on line and everything appears to work and we can successfully move the
resource to Node2. If we try to move it back to Node1 it doesn't give a
drive letter to the disk. There are other physical disks in other groups on
the cluster and failover works correctly for them. If anyone has seen this
before and has any ideas I would really appreciate it. The drives are on a
SAN and there are no errors in the logs of the server or the SAN.

Thanks
Rob

Does the disk resources come online before you assign the drive letter, or
is it offline/failed in MSCS? Do you have any mapped network drives that
might be getting in the way? Have you looked through the cluster.log for
possible reasons why it isn't mounting? (remember, entries in the
cluster.log are in GMT)

Also, there might be some entries in the hklm/system/mounteddevices key that
are causing conflicts. If that's the case, you might want to get PSS
involved so you don't wipe out the wrong entries.

Regards,
John

Hi Rob,

As John Toner advised you, it may be best to get a case created with
Microsoft Product Support Services to further troubleshoot this issue.
Because it sounds very similar to th eone mentioned in the following
article, but we may need to confirm if the article even applies.

819963 "The System Cannot Find the Path Specified" error message occurs
after
http://support.microsoft.com/?id=819963
