OK, I have seen that 2 other people are having the exact same problem as me...

I cannot do a tctl -f /dev/rmt0 reset

mksysb returns:

0512-017 mksysb: Cannot write to the device /dev/rmt0.
                           Either write protected or in use.

Please help.

Many thanks,

Ron

Basically non-IBM hardware are not guaranteed to work.

If you install Linux that will start to work magically.

Ok,

This is an IBM branded drive.

I have run a diag -a on the drive and all of a sudden it works until I reboot the server and then it is right back where is started.

I have rebuild the server and the problem remains.

Any other ideas?

Many thanks for everyone's efforts so far!

Upgrade mainboard (or all) microcode, so it accepts newer drives.

All code is up to date.

The drive is still in the same condition.

Any other thoughts?

install lsof from www.bullfreeware.com and look for database system that holds tape open.
