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.

Message . . . . : 12 blocks processed for sequence 51510, volume 001073,

on device TAPMLB01.

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
