Import physical tape with error 172

Michael, yes, was written by EDl4100, using native exportations. On the tape, mouse right buttom and export. The density is correct.

Markh794, virtual tape media was erased long time ago, also EDL4100 was destroyed.
I will try to do what you recommend, here take time for complete the permission for execute the procedure.

For all, I execute SCSI_COMMAND -MAP and this was the result for the 3 tapes with issue

Something is not good here ...

I saw 00951649: file 2: record 1: size 1024: NBU BACKUP header
 

Is it NBU Header or not?

Is I use tar I saw

/opt/openv/netbackup/bin/tar tvf /dev/nst0
Blocksize = 128 records
Hmm, this doesn't look like a tar archive.
Skipping to next file header...

Is a inconsistency?

Maybe my skills are not enauf for understand this issue ...

Any Comments?

Thanks to all !!!!
