Anyone has any insights as to what I am doing wrong?I am trying to restore a single file from a 5 tape dump.

The tape inserted in the beginning is the correct tape (tape 5).Should I get any message from restore saying that it liked my tape 5 and would now need the next tape ? Because I inserted tape 4 after 5 and got Wrong volume 2.Can anyone explain why it does not say wrong volume 5 but says wrong volume 1. Moreover why does it crap out on me with the 'Tape Block size should be 10240, not 64512' message ? Any help is greatly appreciated.The dump command I used is : dump 0uf urst0a,urst0a,urst0a,urst0a,rst0a /vol/vol0

For the most part, everything is all right.

The first tape you had loaded was tape 1. If it weren't the restore wouldn't have started running at all.

When you told restore you were going to put in tape 5, it kept telling you "This is not tape 5." when you put tapes in that weren't tape 5.

Finally, you put in a tape that was not written with 63KB (default dump) tape records. Instead the tape record was 10KB - hence the message about 10240.

Most likely, that last tape you tried was not part of the dump. Dump writes ALL of the tapes with ONE tape record size, so if the tape record size is 10KB, it is unlikely to be part of the group.

To be sure, you could pop in the final tape, and type: restore tvfb rst0a 10

and see what happens. It will probably tell you something to the effect of "This is not a dump tape."

So, maybe you only had a four tape dump? or the fifth tape is elsewhere? or the fifth tape wasn't rewound when you started?

These are all just theories... You could also just say "Start at tape 4, and pop that tape in." Probability says that your file is on one of the other tapes.

For further diagnosis, I would call NetApp tech support.
