The SCSI spec describes a process called `deselection', whereby a device may temporarily relinquish the bus. I'm just guessing that this feature is supposed to be used by devices when they are requested to perform slow operations, eg. disc head movement, tape positioning, etc. A device driver which does not support deselection is going to have problems performing in a machine used a file server. Since Sun's are used as file servers, I would be surprised if their driver did not support deselection. Can anyone confirm whether it does or doesn't?
