About no rewind device files on UNIX
Although both rewind and no rewind on close device files are usually available, NetBackup requires only the no rewind device file. A no rewind device remains at its current position on a close operation. On some versions of UNIX, the device file name may be preceded or followed by the letter n.
Device files are in the /dev directory on the UNIX host. If the entries do not exist, you must create them. See the NetBackup Device Configuration Guide, available at the following URL:
