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 ID . . . . . . . . : CPI6705 Severity . . . . . . . : 10
Job . . . : BRMCHOB06 User . . : PRODUCT Number . . . . : 324839

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
