You need to specify a device. /dev/rmt8 doesn't exist and hasn't existed for many years. We use this for our dump script to virutally the same device: rdump 0uBbf 2000000 10 resnet2.uoregon.edu:/dev/nrst0 / rdump 0uBbf 2000000 10 resnet2.uoregon.edu:/dev/nrst0 /var rdump 0uBbf 2000000 10 resnet2.uoregon.edu:/dev/nrst0 /usr rdump 0uBbf 2000000 10 resnet2.uoregon.edu:/dev/rst0 /usr1 We use rdump but it's the same idea. The key is the 'f' flag which specifies a device. Note that nrst0 is the no-rewind device, while rst0 will rewind the tape. Our script above backs the machine up putting all the filesystems on one (or more if necessary) tape(s). > tar: can't write to /dev/rst0 : Input/output error > > Do I need to format the tape? If so how do I do that. No, it should work. Make sure the tape is mounted properly and you can see it with 'mt status'.
