Re: 20000920: Problem loading CODIAC data on SAC

Mike,

Sorry to hear you are having difficulty extracting the case study.

I sounds like you received a bad tape. Could you please try extracting the
first tar file rather than fast-forwarding through it? If the tape is
still in the drive, you will probably have to rewind it:

mt -t /dev/rmt/0m rewind

and then just use the same command:

tar -xvf /dev/rmt/0mn

If you are able to extract the first file, try the command again to
extract the 2nd file. If the first file extracts OK, you are using the
correct command on the 2nd file, and you just have a bad tape. We can send
another to you.

If you get a tape error with the first file, could you please send the
message to me? We can then work on it from there.

Thanks,
Liz Page

Liz,

I spent some time this morning trying to extract the files again, with
no luck.  I rewound the tape and extracted the documentation tar file
with no difficulty.  Unfortunately, when I tried to reissue the command
or forward the tape, I kept on extracting the documentation.  (This
included rewinding the tape and starting over at the beginning.)

Could this be a problem with the device file (/dev/rmt/0m vs.
/dev/rmt/0mnb)?

Could it be that I am trying to do this while working midnights? :)

Could we try another tape?

Thanks,
ms

Mike,

We'll send you another tape. Hopefully we'll have it in the mail today.
