We have a situation of running soft recovery to mount the databases from backup.
Here are the details, Exchange 2007 with 4 storage groups and 3 edb files each. For example
Storage Group1(3 database share single log file location)
Performed soft recovery for DB1.edb with /s /l /d /i options and it was successful. We tried for DB2.edb with same options and soft recovery succeeds with
Extensible Storage Engine Utilities for Microsoft(R) Exchange Server

Initiating RECOVERY mode...
Logfile base name: E01
Log files: F:\SG1logs
System files: F:\SG1logs
Database Directory: H:\DB2
Performing soft recovery...
Operation completed successfully in 0.140 seconds.
But still the database shows dirty shutdown. Same result for DB3.edb. We tried by taking a backup of *.chk file before starting soft recovery of DB1.edb and replaced the chk file after DB1.edb recovery. Now we performed soft recovery of DB2.edb which succeeds and DB2.edb shows "Clean shutdown". Why is this behaviour ? Do we need to take a backup of chk file before performing soft recovery ?
Can anyone help in this regard ?

At times our .chk point file might get corrupted.
One other Possible resolution
At this point we can create a new .chk file by having /s pointing to a new location.
Even that should get the database to clean Shutdown.

Thanks for the reply.
"At this point we can create a new .chk file by having /s pointing to a new location.

In this case will the soft recovery process start replaying all the logs or only the logs not replayed? We don't want to replay all the logs as log count is very high.

Exchange begins scanning log files, beginning with the oldest file available, instead of starting at the checkpoint log.
