However, I noticed the following anomolous behavior: You're problem appears that you are not allowing your exabyte to disconnect when it is performing a command. Do you have the disconnection priveledge enabled via the eisa configuration utility? or does the exabyte just not perform disconnections? The SCSI system should be made to handle these types of situtions regardless, but it always comes down to what timeout level is sufficient to deal with targets that don't disconnect, but also discovers devices that are truely hung. I'll have to give this some more thought. If you can't get disconnections to work on your tape drive, go into st.c and increase the timeout for the tape driver. This unfortunately won't deal with commands to other devices that are waiting for the bus to go free, but it may help. >The worst problem appears to be solved, but there would seem to be >a few more dust-bunnies under the couch.
