Unable to mount any mailbox store in a storage group (event id 9518 + event id 454 + event id 494)

yesterday one fo our servers got hang , so we had to hard restart the server

once the server got up again we found that all mailbox stores under one storage group failed to brign online

and we found that the below 3 event log appeared in the event viewer :

Event Type: Error
Event Source: ESE
Event Category: Logging/Recovery
Event ID: 494
Date:  6/24/2012
Time:  1:46:51 AM U
ser:  N/A Computer: server1
Description: Information Store (8676) Storagegroup1: Database recovery failed with error -1216 because it encountered references to a database, ‘G:\EXCHSRVR\StorageGroup1\MAilboxstore1.edb’, which is no longer present. The database was not brought to a Clean Shutdown 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, procedures for recovering from this error are available in the Microsoft Knowledge Base or by following the “more information” link at the bottom of this message.

we have tried to do soft recovery for mailbox store mailboxstore1 by running command eseutil /r “logbase” /l “Log path” /d “Database path”

but it failed and could repair the Database softly

the problem here was because the path of the DB and the path of the Logs wasn’t the same, so we moved the DB files to the same path as the logs and try the command one more time, and it success and could mount the all mailbox stores
