I am trying to restore a tape from a FreeBSD machine on a Sun. What kinds of problems should I expect?
The default blocksize should not be a problem, since they are both 20K. You may need to use “dd if=/dev/rst0 conv=swab | <archiver>” instead of extracting directly from tape, just in case the byte order causes a problem. This is especially true if you don’t use the ‘a’ and ‘c’ options in cpio, for example. 5.4.15 : 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
