Restoring a database using TSM (Tivoli Storage Manager) from LiteSpeed GUI hangs with LiteSpeed 4.5.157.
The @tsmbrieflist=1 parameter has been removed from the GUI causing the SQLLiteSpeed engine to query TSM to open EVERY SINGLE backup to read in the full xml to create an extensive list.
Quering TSM to open every backup can take a very long time on TSM servers with tape pools, as the tapes are all mounted, thrashing back and forth between mounting of different tapes.
The @tsmbrieflist=1 parameter causes SQLLiteSpeed engine to read in a smaller subset of information stored inthe TSM catalog for each backup.
Using the restore by the script using the @tsmbrieflist=1 parameter.
Waiting for fix in a future release of LiteSpeed for SQL Server.
Applies to LiteSpeed 4.5.157 only.
