    Persistance binding is required at OS level to make sure that the Drive paths are not chaning...

First of all, check if broken tape device links existed at that time. It sometimes happen that broken link is removed during reconfiguring boot and link name for actual devices become adjusted.

For example, when /dev/rmt/0 is broken link and /dev/rmt/1 is link for actual device, broken link will be removed and link for actual device is renamed to /dev/rmt/0 during reconfiguration. This lead mismatch between OS configuration and NetBackup device managenet. SO, it is very important to keep device links clean anytime.
