I'm running into issues with hard-coding some devices (see recent post titled 'device.hints isn't setting what I want'). Associated with this issue is confusion over whether I want to use ch0 or pass1. I have these devices: at scbus1 target 0 lun 0 (ch0,pass1) at scbus1 target 5 lun 0 (sa1,pass2) My understanding: chio(1) will with ch0, whereas mtx(1) will work with pass1. Is this correct? More information/elaboration will help I'm sure. Why do I ask? I can get the tape changer and tape drive hardwired to ch0 and sa1 respectively. I cannot [yet] do the same with pass1. Thanks folks.
