When performing a manual restore from a RAIT tapeset, you can just use amrestore with the rait device name, like so:
$ amrestore -f 10 'rait:/dev/rmt/tps0d{4,5,6}n'
If one of the devices in a RAIT array fails, you can specify it with the string ERROR to get a read-only RAIT device capable of supporting restores. This works both for amrestore and in amanda.conf(5):
tapedev "rait:{/dev/rmt/tps0d4,ERROR,/dev/rmt/tps0d6}"
If you're using chg-rait, you can specify ERROR in a similar fashion to enable read-only use of the RAIT changer:
tpchanger "rait:{robot1,ERROR,robot3}"
Other than these details, restores from a RAIT device are like any other kind of restore.
