What are the jumper settings for the Archive Viper tape drive?
Vipers can’t do auto-detection. You have to create different devices for different densities. Minor number 8 = 120Mb, 4 = 150Mb and 12 = QIC-24 (60Mb). At least this is the only way it works for me, and since it do I haven’t bothered to find out why minor 0 doesn’t. If you have a 2525 (525Mb) it uses ST_Q_SENSE_HELP quirk but it might not work. The cfg0-2 switches is for setting the disconnect size, e.g. the maximum size transfered before disconnect to allow other SCSI devices to access the bus. Jumper in sets bit to 1. 0 = 2kb 1 = 4kb 2 = 6kb 3 = 8kb 4 = 12kb 5 = 16kb 6 = 24kb 7 = 32kb I’m using my viper at id 4 and disconnect size 16k. Works perfectly. 5.4.16 : My Viper-150 auto-detects fine; however, the first attempt to read a tape fails after a boot due to an “illegal SCSI command”. What could be the problem? I assume that the driver is trying to use some SCSI-2 command to set the default density — but after that, the drive is perfectly happy to do the tedious density check and o
