As you can see here DB030 shows as Failed for DAG Member EXM15, to get this fixed we have to reseed the DB.
Step1: Suspend the Failed DB by executing the below command
Suspend-MailboxDatabaseCopy -Identity “B030/EXM15”
This will ask your confirmation to perform the Suspend for this DB/Server, Select A [Yes to all]
As you can see below
Step2: Update the Failed Mailbox DB copy from the Active one, by running this shell and Make resume it.
Update-MailboxDatabaseCopy -Identity “B030/EXM15” –DeleteExistingFiles
Note: The duration of the seeding process will depend on the size of the database and the speed of the network. When the update has completed it will automatically resume replication for the database copy.
Just in case if you want the replication to resume it manually use the below command.
