DescriptionInformation Store (1728) Database recovery failed with error -1216 because it encountered references to a database, F:\Apps\Exchange\MDBDATA\MBX-AUSXMBT102VS1-SG1-2.edb, which is no longer present. The database was not brought to a consistent state before it was removed (or possibly moved or renamed). The database engine will not permit recovery to complete for this instance until the missing database is re-instated. If the database is truly no longer available and no longer required, please contact PSS for further instructions regarding the steps required in order to allow recovery to proceed without this database.
Event InformationAccording to Microsoft:
WORKAROUND:
To work around this behavior and replay the logs, you need to copy all of the transaction logs that you want to recover to the temporary restore folder that you defined in the restoration process. To copy all of the transaction logs that you want to recover to the temporary restore folder and then replay the logs:
1. Restore all of the online backups to the recovery server.
2. Copy all of the offline log files to the temp_restore_folder\storage_group_name folder, where temp_restore_folder is the temporary restore folder that you defined in the restoration process, and storage_group_name is the name of the storage group.
3. Make sure that the log files are contiguous. Log replay only plays forward as long as the sequence is contiguous; when this sequence is interrupted, replay stops.
4. After you are satisfied with the state of the log files, change directory to the temp_restore_folder\storage_group_name folder, and then run either of the following commands:
c:\exchsrvr\bin\eseutil /cc
-or- c:\program files\exchsrvr\bin\eseutil /cc
These commands force an Eseutil manual log recovery.
