<Then run a second STRRCYBRM command and pick the libraries on the second tape.
Is there any way the BRMS recovery report could break this out, list which libraries for which volume?
< make sure journals are down first for all the libraries
Why is this important?
In our one application the journals and journal receivers are stored in the same application library.
So when using BRMS STRRCYBRM , how would you control that journal/journal receivers get restored first?

Previously the hardware resources were not available for practice. Now there may be enough resources for practice.

Questions
1) Has anyone ever used multiple drives for the BRMS recovery of the *ALLUSR
libraries backup item.
Yes, frequently. Works well particularly when you have several small
libraries and one or two large ones. Restore however is single threaded
since each library will be on a single tape. What I do in this case is use
the STRRCYBRM command and pick the libraries on one tape to restore. Then
run a second STRRCYBRM command and pick the libraries on the second tape.
You can't be in a restricted state but you can have the system severely
restricted.
Just make sure to restore all the journals/journal receivers first.
From what I've read and been told, if the original BRMS save was done using
4 drives, then one could start four interactive STRRCYBRM OPTION(*RESUME) to
reduce the down window.
Pros/cons on this?
Yep, do it all the time as I just pointed out. Pro, four restores going at
once. Con: make sure journals are down first for all the libraries and I
would do QGPL/QUSRSYS before any others. Disk I/O likely will be a bottle
neck.
2) Once an LPAR has been tested, I'd prefer to NOT clear the ASP for final
migration, but rather delete all user libraries and recover only those.
Pros/cons on this?
The eliminates significant work on the system end but you keep talking about
an ASP, why? If youi have the network server storage in an iASP for PowerHA
I can see it but I don't see the value in using standard ASP other than to
add complexity.
3) Any other migration or recovery suggestions from the group?
Practice makes perfect.... You'll learn something everytime you do it.
