Hi again. I tried the recommended post. Didn't get far though. Couldn't get the thing to perform a switch. It states you use the command- /usr/bin/sg_raw /dev/sr0 11 06 20 00 00 00 00 00 01 00 to switch with sg3_utils. I get- do_scsi_pt: Bad address. I don't know what the numbers represent in this command but I'm assuming it's that. I've posted a message on the other post(waiting for reply) but I thought I'd try my luck here as well. Cheers
