Scott,
Don't use Disk Manager in Computer Management to determine if the disk came
Online on the other node or not.. Because if you are viewing the node via TS
session, it may not refresh correctly.
Test the failover like from node A to node B, once failover has settled down
after the move to node B then open Windows Explorer on node B and see if you
can access the disk that are on that node. Make sure to check the Cluster
Logs and System Event Logs on both nodes for any errors after the failover.
What is the exact verbatim of the error?
