RE: P7 to P9 test migration/recovery using BRMS - noticing significant tape seeking, unloading, loading during the recovery

I stopped the recovery.
I changed end of media option from *REWIND to *LEAVE.
I restarted the recovery, selecting only the sequences that were sequentially in order.
All seeking, unloading, loading eliminated.
Result was a streaming restore.

Is there an option to present the BRM recovery items in sequence order?

Subject: P7 to P9 test migration/recovery using BRMS - noticing significant tape seeking, unloading, loading during the recovery

I'm testing a P7 to P9 migration/recovery using BRMS, 3573 Tape library with 4 LTO7 drives.
My original system save was using BRMS, using all 4 drives, 4 volumes.

From the BRMS recovery report, I can see that different volumes were used.

I set the BRMS recovery to use all 4 drives.

I'm noticing significant tape seeking, unloading, loading during the recovery.
But with BRMS set to use 4 drives, I'm not sure why this is occurring.

Any thoughts from the group on improving the BRMS recovery?

Thank You
