Disk addition and LTO1 backups

[<jvoris@xxxxxxxxxxx>]

I have a similar setup LTO1 on Fibre, no LPAR,
but when reviewing the SAVSYS I have problems with the /QNTC trying to
touch other hosts in the network, and this lengthens my backup horribly.

Look at the joblog.   Suspect some other factor is causing the problem.

We have an LPAR on an i570 that had a little over 1TB of disk space and
backed up, using BRMS over fiber, to dual LTO1 drives. The backup time
was approximately 3.5 hours give or take depending on the usage of the
system. A while back we added 400GB of disk to the LPAR that is now at
approx. 1.4TB. With similar disk usage to before (not percentage, but GB
used), our backups are now taking over 6 hours. Has anyone ever
experienced this or have an explanation?
