Paul,
Are the devices set in BRMS Backup Devices? If there are multiple I think
BRMS is going to grab the first one available where it can match the device
and an available tape cart. Then it pays attention to the parallelism
that's set.
I don't know of another way to find the device that was used, but I have to
wonder if that is in the BRMS database somewhere that we could run and SQL
to find it.
Maybe post a question on KnowledgeWorks and let Mervin pipe in?
You might be correct about the device, assuming it's been cleaned; it might
be getting out of alignment. What do the stats in SST say about it?

Subject: Possible TAP02 drive issue
I noticed that both backups from 2 different LPARS took extra time, longest
they ever ran.
No errors logged on the 3573 Tape library or on either LPAR.
I reviewed BRMS log, each library took a bit longer than normal.
Additional research revealed that both LPARS used TAP02.
Previous nights, a different TAP device was used.
Our config is Power7 740 8205-E6C, V7R1.
BRMS
3573 LTO5 with 4 HH FC drives.
1) Is there an easy way to determine which TAP device is used daily, for
both saves and/or dups?
To the best of my knowledge, you can only see which TAP device is used at
the end of the CPI6705 message.

Cause . . . . . : 12 blocks were processed for file label CHRISV, sequence
51510 for volume 001073 loaded on device TAPMLB01. The maximum block size
is 262144. The tape file was opened at 04/15/15 18:55:21 and closed at
04/15/15 18:55:21. The total time the file was open was 0 seconds. If the
device is a tape library the cartridge is 001073 and the resource is
TAP02.
2) I suspect TAP02 is having an issue, possibly doing retries within the
drive. These retries are not logged, but would explain for longer run times.
Thank You
