Unable to open the physical file , operating system error 5. (Access is denied)


1. Add permissions to the disk contain Data and Log files
2. Add service account to login with SA
3. Take DB offline
    Alter database DB_NAME set offline with rollback immediate
4. Bring back the DB online
    Alter database DB_NAME set online with rollback immediate

this resolves the issue, else we need to try restarting SQL Services. Worst-case we need to restore the database with latest backup.
