Don't want to go on Repair option right away as this is critical DB and Size of DB is approx. 150GB.
TIME is really short, need to get this up before working hours start.

What happened before this? Are there missing logs? File system corruption?
AsifAuthor Commented:
A "volume copy" was done to move underlying storage volume to new storage.
This was done at storage level. after copy was done, the new is set to primary and old is still in sync as secondary.
Other databases is mounted except this one.

Better you focus on storage part. Also going forward, always move your sever into maintenance mode, before you perform any server level activity.

Thank you Casey for trying to help and the link you shared.
Due to lack of time and need to get DB online ASAP, couldn't dig into  the problem, but search for possible reason and fix will keep going.
In this short period, multiple things might have caused the problem.
May be for some reason the database did not commit logs during the VM shutdown process.
As the underlying volume was copied it might have caused.

Important thing "Keep Backup Clean", Before performing any maintenance task schedule a FULL backup. Know the backup window and Time required for FULL backup.
