The 'mt offline' in mtx-changer until now (because I had not understood the option you describe below) has been necessary to work with the Q47, as it does not take the drive offline before issuing the unload to the changer. > I've taken a quick look at the code and see no obvious reason why things > should break if AlwaysOpen is off.

I have been able to run a clean regress 'all-non-root-tape-tests' on the Overland, with no change to the regress scripts. I can run a clean regress on the Q47 with one mod to scripts/prepare-two-tapes to uncomment an offline. ================================== #!/bin/sh # # Create two blank tapes # mt -f /dev/nst0 offline <=========== uncommented /usr/sbin/mtx -f /dev/sg2 unload ... ================================== I will keep you posted on the status of the SD changes, and thanks again. -- -- Michael ------------------------------------------------------------------------- Using Tomcat but need to do more?
