At a disaster recovery test I may need to restore several hundred files from several hundred different Virtual Volumes. Those Virtual Volumes may have been stacked on a hundred different Backstore Tapes. If I run a job to issue Recall commands for all of these data sets at one time, how many can CA Vtape VTS actually process at one time?


The CA Vtape VTS Backstore Engine has a limit of 99 subtasks it can start. Therefore, 99 recalls can be done at one time.

When you issue the Recall commands, the Backstore Engine will start a subtask for each Recall. If a Recall command is seen that requires a Backstore Tape that is already mounted by a subtask, the new Recall will be queued to that subtask.
