I have done that and use collocation groups already so I understand the
ramifications of this, but those are not my questions. My questions are
more specific to restores and was wondering if a single session with 4
drives checked to restore will mount 4 tapes immediately or will they
possibly be single threaded and one drive at a time is truly what is
happening. If not has anyone tested this and compared to 4 sessions
restoring a single drive with each session to see if there is any
difference in the amount of time it takes to restore the data?
