Hello

OS Version AIX5.2
Netbackup Version: Netbackup Datacenter  4.5 FP4
Tapes are FC Attached
  First Library  3584 uLtrium  IBM
second Library  3494 Library (IBM)

Since a few days i had a problem with duplicating tapes to a 3494
Tapelibrary  ( IBM)

Netbackup mounts the tape and the drives are going downn.
This problem occurs with automatic vaults and manuell doublecating

Iventory to this library no problem.
Duplicating works fine  until last Monday
Robtest to this Library  no problem
Hardware support finds no problems on the Library
mtlib commands to this Library no problem
mtevent -l /dev/lmcp0  shows that the tapes are mounted

I deinstalled the whole Libraryr the Lmpc Driver  and do all definitions
new but this doesn't solve the problem

Has anyone seen this problem  before ? Has anyone  expierence with this
Library and Netbackup


With Frendly regards
Mit freundlichen Grüßen
Felix Mülbaier
