I had the same problem. It appears that somehow the info missed the 7.0
release package.

In my case the minor number was the problem. The major number is found in
the /etc/masters file. Anyhow, the two line below should get you going.

crw-rw-rw-   1 root     sys       54 0x0e0502 Jul 30 19:07 /dev/rmt/0m
crw-rw-rw-   1 root     sys       54 0x0e0503 Jul 30 19:06 /dev/rmt/0mn

The format for the minor number is standard HP conventions, that is the
first 2 digits correspond to the SC of the interface card, the second 2
digits correspond to the SCSI unit address, and the last two digits are
device specific ( which I can't remember right now) but I think are as
follows:

	LSByte of Minor #

	Bit 0		immediate report mode on/off 
	Bit 1		berkeley style rewind on/off 
	Bit 2		at&t style rewind on/off

If you use the above names, you can check that the tape works but firstly
loading a tape (wait till the lights stop flashing) then issue the follow-
ing and it should unload the tape.

	mt offl

To see if you can read from the tape (ie you have the right address) try the
following:

	od -x < /dev/rmt/0m | more

To do something useful try the following:


	cd /
	find . -print | cpio -ocdumvB > /dev/rmt/0m

If you use some other naming convention check the mt (1) man page on how
to specify a different dev file.

PS
The first entry above WILL rewind the tape when you have finished accessing
it, whereas the second entry WILL NOT rewind the tape.
