I am not using the library in library mode, but rather in SEQ mode so that
is not an issue. Sue Baker from IBM does say I can place the card in VIOS
and virtualize it in such a way that 2 partitions can use using the same
card at the same time as long as they are using different SAS ports. I will
know first hand in a few weeks once I standup my Power8 that is on order.

Kirk, you wont be able to. A virtualized SAS drive cannot be assigned to
more than one partition at the time. Your script will have to use an SSH
command to move the rmtX to the next partition, I've just done that. So
either move the entire card the same way you always did or lose the library
feature and virtualize with VIOS AND use a script to move it (not worth it
in my opinion).

Best Regards,

Roberto

Timing takes a little practice... I know how each of my backups take
with a
little fudge factor tossed. Since all my partitions are IBM and I have
Object Connect setup ( you could do this other ways ) I do the following.
I have a dataarea defined on each partition. When backup A finishes I
first
vary off the drive and via a CL tell the HMC to Move the SAS Adapter to
partition #B. Then I set a value in that dataarea and SAVRSTOBJ to the
next partition where a program is checking the dataarea for the OK to
start.. I then set the dataarea back to a value for You Can't Start Yet
and
end partition A.
Repeat until al the backups are completed. With the new Power8 I am
going
to switch to virtualized tapes drives on a single SAS card owned by VIOS
so
I won't have to worry about have the HMC move the card and I can run both
drives a the same time with a single card fro 2 partitions.

Ok. Like I said, I would be too worried about the timing of each
lpar's
backup. We already have the tapes needed. And what we send back and
forth with Iron Mountain fits into the cases used. So it's not a grind
for us.

Rob,

Already asked years back.
A BRMS volume can only be owned and used by one LPAR (system).
I wanted to use the same volume for all my nightly backups, and dups.
Could not be done.

Kirk,

Have you thought about submitting a DCR, or a COMMON requirement, to
allow
BRMS to stack multiple lpars onto a single tape?
IDK if we could use that as I would be concerned about timing the saves
on
each lpar.

Because we Stack our backups from multiple LPARs on a single tape each
night we can't use BRMS ans SEQ. Mode works just fine for us. Thanks I
probably won't hear back from Techline for Several More Business Days.
