I have a Proliant 3000 server with a 9 track 6250 bpi tape drive
connected over SCSI.
the Device id used is /dev/rStp2.
However I am not able to do any read/write on the drive. The tape
loads, rewinds with the </dev/rStp2 command.
dd moves the tape but give 0+0 in and out.
Please let me know any furthur step in trouble shooting this.
Woudl really appreciate any help
Thanks in Advance

Try:

dd if=/dev/nrStp2; dd if=/dev/nrStp2

(probably multiple data sets)

Writing to 9 track tapes sometimes requires a plastic ring be inserted
on the reel. This is alternatively known as a write-enable ring or
write-protect ring, depending on whether you are IBM or not, and I
forget which way it is.

Your tape may have been written in EBCDIC.

Your tape may have EOT at the beginning for some reason - I forh=get the
reasons why this can happen, perhaps others can jump in.

Does one dare suggest checking permissions on /dev/rStp2???

It is 'write-enable'.

This brings to mind the story of person who wanted to make sure
than no one wrote to an important tape so he filled the cut-out
where the ring was placed with expoxy - so no one could put
a ring in place. Of course the expoxy acted just as if the
write-enable ring were in place.

Kind of a magic ring then? Sounds like LoTR.
