We did a DR test and it became the disaster:
· All the member of DAG cannot start cluster services
· All the database in DAG is dismount
SO we have to mount the production database back ASAP. Here we did:
1. Check if the database is clear shutdown or not
· Go to the database files location folder
· Run eseutil with /mh switch
eseutil /mh xxxdb08.edbs
· Make sure the database is “clean shutdown”
· If the database is dirty shutdown, run eseutil R option
eseutil /r e03 /dD:\MPs\DB07\DR_XXXDB08
2. Create new database on the DR server and mount the new database.
3. Make sure “this database can be overwritten by a restore is checked
4. Unmounted the database
5. Rename DB DB file to another name
6. Copy the database file to the DR DB location
7. Rename the DB file to DR DB file
8. Mount the database
If the database is mounted, run the script to update users’ homeMDB info:
Get-mailbox –database |set-mailbox –database
It is back to business. But user have to restart the outlook.
