Hi All
I have a problem, i was in the process of restoring my SAP DEV box from a Production tape, then it compalined about a path in the restore script that i was using. I edited the script then when i tired to run the command tar -tvf PRD-NODE0000.scr it started giving me the error directory chesum error. i am on hp-ux 11.23 and db2 database.
Thank you

can you try or check with "options" -i
sometime "tar cannot look into the symbolic links

or tar -tvf /dev/rmt/0

"tar" sometimes says "directory checksum
error" when some I/O error occurs, or when
it's confused in any way by the contents of
the archive.

Is the actual error message a secret, or
could you share it?

> [...] I edited the script [...]

That explains approximately nothing.

Showing the actual commands you're using with
their actual output is often more helpful
than vague descriptions and interpretations.

> i am on hp-ux 11.23 [...]

Are you using the same "tar" program to
create the tape and to read the tape?

Did you rewind the tape? Did you compress/gzip it when you wrote it?

Are you sure backup was completed properly.
checksum error suggest some problem in making tar.

well are you getting any good output for
tar tvf file.tar.
