You should have some fairly extensive information in the event log on both source and target server. That's what I would be looking at.

When I received the following error message. "An active manager operation failed. Error: The database action failed. Error: The database was not mounted because it has experienced data loss as a result of a switchover or failover, and the attemp to copy the last logs from the source server failed. The copier will automatically retry after a short delay. The delay has not been short about 1/2 hour so far. Any suggestions as to my next course of action. -- T. Todd Lemmiksoo -- T. Todd Lemmiksoo
