I am at a standstill trying to get the Compaq DLT400 working with the Dilog SQ703. I can issue an mt off command and it gets a data error. If I try any LUN other than the one selected on the drive (and in controller firmware), I get mt: /dev/mt1: Device not configured. So the driver is trying to go out on the SCSI bus and access the drive.
The on-board firmware
diagnostic monitor of the Dilog controller only allows me to
send SCSI commands in HEX, but does not print the response. If
I try a 1B - eject command, it just reports that it has sent it.
Does anybody know of any troubleshooting aids to read SCSI bus data from the driver, maybe a driver in debug mode? Short of a SCSI bus analyser I don't see how to proceed. I have a logic analyser but it is only 8 channel!
any help appreciated!
cheers,
Nigel
