HPUX : How to check whether Ignite archive fit into a single Tape

Steps to determine if the data archived fits into a single tape:

To determine if a tape created by Ignite-UX versions C.7.11.439 or C.7.11.444 on an HP Integrity system is not valid, run the following commands:

# mt -f /dev/rmt/#mn rew
# mt -f /dev/rmt/#mn fsf 22
# pax -v -f /dev/rmt/#m

where # must be replaced by the number associated with the device that the tape has been loaded into. 

If the archive listing by pax completes without prompting for a new tape, the recovery tape has been created successfully. If you are prompted for a second tape, the recovery tape is not valid and should not be relied upon for recovery.

# pax -v -f /dev/rmt/#m

this will show long listing of content of the file in the tape.it should complete without the asking for the second tape. if it ask for second tape then, archive for recovery is incomplete.
