[About a year ago there was a thread on freebsd-questions about Exabyte 8200 drives which I would like to revive with the hope that someone found a solution.] On Thu, 2 Dec 1999, Greg Lehey wrote: :On Thursday, 2 December 1999 at 15:17:47 -0600, Eric S.

Mine is reported as "<EXABYTE EXB-8200 IRM4> Removable Sequential Access SCSI-CCS device". This was a drive Exabyte made OEM for IBM and was sold in RS/6000s ten years ago, white faceplate and round blue eject button. I am aware that it is a piece of crap - if I can make it work this whole machine is going to a charitable cause, otherwise the drive goes to the dumpster. I have it attached to a SCSI bus with a hard drive attached (id #0). The tape is id #1. The host adapter is an Adaptec 2930C at id #7. I have verified no SCSI ID conflicts by removing each device and probing. I get the exact same error message when I 'mt -f /dev/rsa0 status'. I am running a 4.1.1 GENERIC kernel (freshly installed OS). :>>> Any help in mounting this beast and get backups done would be appreciated. :>> :>> Type changing dup switch 4 to on, on the MX Card. :> :> Thanks for replying. I unfortunately must show my ignorance and ask "What :> is an MX Card?" Are you referring to the SCCI controller or a card :> physically attached to the tape drive. : :I believe the MX board is the second from the back ot the unit. You :should see an 8-position DIP switch on the right (looking from the :front). Unfortunately, the units I have have special screws for which :I don't have any screwdrivers available here. I'll see if I can :arrange something tomorrow. The small screws are Torx T-8 and the large are T-10. Examining the MX 2 card DIP block, factory settings were different from what I find on Exabyte's web site. They say default is all switches "off". http://www.exabyte.com/suppserv/techsupp/8mm/fullhigh/in0011.html On mine, switches 2, 3, 4, 5, and 8 were on by default (ie, for use in an RS/6000). I tried moving all switches to off, and all switches off but 4 on. When switch 4 is _off_ the drive returns an error immediately after an 'mt -f /dev/rsa0 status'. If switch 4 is _on_ it takes about 10 seconds and then returns the same error, after blinking the drive lights and making it's little Exabyte tape tensioning noises. I realize that Exabyte shipped drives with insane firmware variations (especially OEM) but this drive previously worked (a while ago) in a Linux box (Intel hardware) with a 1.2 kernel, which seems like a good sign. If anyone has the dirt on this drive, please drop me a note. --Paul Copyright (c) 1992-2000 The FreeBSD Project.
