Update on this issue.
I am happy to report that NetWorker will, in fact, mount tapes which
have no headers. It spends some time synhronising with the blocks it
finds and then the tape is ready for use.
I used mminfo to check the tape position of the data I needed.
(mediafile, mediarec).
Then using scanner I verified that starting filemark of the tape was
lower than the tape position of the data (i.e. the data was on the tape
and had not been overwritten)
Then restored the data.

Subject: [Networker] Recover SQL data using scanner
Hi all.
I have a networker tape with a corrupted label. When I run scanner, it
synchronises with the chunks after an initial error message and then
proceeds. I suspect that it was caused by the tape drive being reset
during the backup, which causes it to rewind and then continue writing
data. As a result, the tape label and the first, say, 50 filemarks are
gone.
I need to recover a SQL DB off these tapes if possible. I know that
you can use scanner to extract a saveset and redirect this through usam
to restore filesystem-based data.
Does anyone know if you can redirect data through nsrsqlrc.exe (or
anything else) to recover a SQL database
Alternately I could possibly write/clone the saveset to a correctly
labelled tape (or a file device) and recover from there.
Does anyone know how to do this ?
Regards,
John Hope-Bailie
