- I think this is because your drive is not set to fixed block mode for
- restore which it was during dump. What I do, and this has ALWAYS worked,
- is a
-
- localhost:4# restore i
- /dev/rxt0: I/O error
-
- Then I do a
-
- localhost:5# restore if /dev/nrst0
-
- and the restore works just fine. The default device for tape is /dev/rxt0
- which, if I remember correctly, is a exabyte device which uses a fixed
- block length....
-
- I hope this helps...
