Dual Secondary Virtual Disk Conflict

What Caused the Problem?

A role change from primary to secondary was attempted while there was a connection problem between the local and remote storage arrays. The user chose to force the role change which demoted the local primary virtual disk's role to secondary without promoting the remote secondary virtual disk's role to primary. The connection problem was subsequently corrected making the remote virtual disk visible again. This resulted in both virtual disks being in a secondary role. The Recovery Guru Details area provides specific information you will need as you follow the recovery steps.
