Linux device persistent binding changes
Starting with NetBackup 8.1.2, the NetBackup Device Manager (ltid) uses persistent device paths for tape drives. Instead of /dev/nstXXX device paths, NetBackup uses /dev/tape/by-path/YYY-nst device paths. The paths persist across SAN interruptions. Upon NetBackup Device Manager (ltid) startup, /dev/nstXXX paths are converted to the equivalent /dev/tape/by-path/YYY-nst path. For more information, see the NetBackup Device Configuration Guide - Operating Systems - Linux chapter.
