If the database or logs on the passive node are corrupt, use either of the following procedures to
recover data.
To recover from failure on the passive node
1. On the Exchange server, in Exchange Management Shell, run suspend-
storagegroupcopy for the failed storage group.
2. Delete all .logs, .chk, and .edb files from the copy location (passive node).
3. In the DPM Recovery Wizard, copy the database files without running database clean
shutdown to the passive node.
4. Move the files to appropriate locations in the passive node.
5. Remove the common log files (between active and passive nodes) from the passive
node. For example, a failover might have created a new log stream with the same log file
names.
6. On the Exchange server, in Exchange Management Shell, run resume-
storagegroupcopy for the failed storage group.
To recover from failure on the passive node (if both copies are corrupt)
1. Set the Exchange Server database property Override by restore to True.
2. In the DPM Recovery Wizard, recover to the active node.
3. On the Exchange server, in Exchange Management Shell, run get-
storagegroupcopystatus to verify the copy status.
4. After recovery, synchronize the passive nodes with the active node.
