You are running into persistent binding issues, or lack there of.  This is
accomplished by a couple different methods depending on you Linux version
and HBA model.  NetBackup has a solution built in to the volume manager portion
of it.  If you add the following entry in you /usr/openv/volmgr/vm.conf file:

ENABLE_AUTO_PATH_CORRECTION

This may take care of your problem most easily.  Not sure which version of NBU
you are working with as that is not in your email.  More details up front
in the message allow others to help more easily.

Thanks
Peter
