About SCSI persistent bindings for Linux
Veritas recommends that you use persistent bindings to lock the mappings between the SCSI targets that are reported to Linux and the specific devices. The Linux kernel device manager udev creates the /dev/tape/by-path symbolic links to /dev/nstx device paths that NetBackup uses to communicate with tape drives. The udev system creates the persistent paths using the /dev/tape/by-path symbolic links. Do not change the default udev rules that create these paths.
If you cannot use binding with the HBA in your configuration, add an ENABLE_AUTO_PATH_CORRECTION entry in the /usr/openv/volmgr/vm.conf file on all Linux media servers.
