We want to remove SnapManager for SQL from our SQL server. Since this software handled storage management of SQL server, we are afraid of the side effect.
SnapManager is managing the schedule of backups and interacting at backup time to facilitate the VSS quiesce of the system, interacts with SnapDrive for the snapshot, etc. Removing SMSQL should not have an impact. However,*SnapDrive* is managing the LUNs and SQL is being directed to those mapped (or mounted) drives (!)
SMSQL can be removed, but SnapDrive should be left in place (and has benefits of its own).
