SQL Cluster Move group failed

We tried doing the Move Group operation on Cluster Administrator today. This is part of the regular maintenance. This time it failed on Node2 and here is the message from Event Log: The description for Event ID ( 36865 ) in Source ( SANworks Virtual Replicator ) cannot be found. The local computer may not have the necessary registry information or message DLL files to display messages from a remote computer. The following information is part of the event: All attempts at assigning drive letter T: failed, Error = 2. Did anyone knows why this is happening ? It mapped all the other drives but it failed to map Drive Letter T:. I tried to map the drive manually but it failed again. We moved the cluster back to Node1. Thanks,
Sounds like there is an issue with the underlying SANworks Virtual Replicator software that you use. What do you mean with that you manually tried to map the drive? From a command line? Does it not exist in the cluster as a disk resource? If you get error 2 from the OS it means "The system cannot find the file specified."

Thank you both for your reply. I tried assigning drive letter using Snapshot Manager. It was a software used for SANWorks Virtual Replicator. We have applied MDAC updates recently on Node2. This is the only changes we have done since the last move group operations. Thanks,
