after using the dump command on a sunos 4.1.3U1.
i use "mt -f /dev/rst1 status" to view the tape status

is there another command I can use after I backup the data on tape to verify the partition had been backup properly?

mt status
just tells you the status about the tape currently loaded, it does not know anything about data and/or verification, this must be done by the dump command.
Does dump have a verify option somehow, otherwise you must read back your tape and verify yourself (usind diff, cmp, etc.)

Hi
Use either:

restore tvf /dev/rst1

to verify and display the tapes contents.
or

restore ivf /dev/rst1

to enter interactive mode where you can check the contents and exit without actually doing a restore.

You could even create a script to carry out your dump then check it was successful and then create a file listing the contents of the tape. Very basically:
#!/bin/csh
dump 0uf /dev/rst1 /partition
if ($status) then
   echo "dump failed"
   exit 1
endif
restore tvf /dev/rst1 > /backup/TOC_`date +%m-%d+%y`
