I having an Adaptec SCSI adaptec AHA2940AU and an EXABYTE Tape Drive on the
controller with Fsys.aha7scsi.
I’m trying to do backup with cpio, tar or pax, i can write, but i cannot
read it back.
I’m doing a tape rewind before and after the backup command.
I cannot do a tape rewind erase.
Can you give me some hints.
without more info i don;t think the community can help you.
some thoughts though:
search qdn.qnx.com for ‘tape’. you will see some notes that could be
helpful
the fsys and drivers will write data to the trace log on error conditions.
you can examine these logs with the ‘traceinfo’ command.

Should just be pax/tar commands
Ensure you have proper priviledges to the Tape device /tp0 or /dev/tp0.0
Otherwise for SCSI Tape should be little different from drive to drive.
See these scripts for examples (Attached…):
Note that varying the -b Blocksize value can increase performance (for me 1hour->6 minutes on 240MB)

- the ‘tape’ command can print status… ‘use tape’ will show the different
commands. the output of that command when you can’t do a rewind would
be useful.
