Help/mes says
Data in the save set is corrupt.

Clean heads ? Bad or very old tape ? Show error command reporting drive errors ?

Hi Edgar,
Collapse the 2 /ignore qualifiers into one, as /IGNORE=(INTER,LABEL). I forget which way this works, but one of your /ignores is being ignored.

There's a problem in the v731_fibre_scsi-v0700 kit. Engineering released a remedial sys$pkwdriver to address this very problem. BACKUP returns "SHORTBLOCK" error when reading tape savesets. There will not be an official ECO kit, since V7.3-1 is no longer supported.

Send me mail to jeff.chisholm@hp.com and I'll put a copy on the ftp site for you.

Edgar,

thanks for providing a detailled error message. This really helps in identifying the problem.

I was clean the tape heads,

yesterday I was backup in new sdlt tape and the backup was without error.

only the backup/list and restore show me the message again.

im in ods-2 and probably the patch will help to me.

Thanks

I pulled down a copy of the SYS$PKWDRIVER.EXE_QXCM1000243254 and placed it on the ftp site for Edgar, with directions for checksum-ing and loading it. We just got lucky this time, usually the recommendation is to upgrade.

Edgar,

it may look fine, if backup does not produce any errors while saving the files to tape, but you're really interested in what's on the tape afterwards !

As was said in a presentation at the OpenVMS Technical Update Days:

'You do NOT need to test your BACKUP procedures, just test your RESTORE procedures !'
