We are running a two-node Exchange 2003 cluster, and are in the process of migrating the storage to a new SAN. After adding the new disks, we can not move the Exchange cluster group over to the standby node. When we try to move the group, three of the four new disks show up as 'Failed' then it fails back. Everything works fine on the current node. The three disks contain a mixture of Logs and DBs. All of the disks have been added as dependencies for the MS Exchange System Attendant cluster resource.
When we attempt to move the group, we get the following System Event for each disk that fails:
Event Type: Error
Event Source: ClusSvc
Event Category: Failover Mgr
Event ID: 1069
Time: 7:23:47 AM
Cluster resource 'Disk J:' in Resource Group 'Exchange Group' failed.
