I call this Psuedo-standard labels because of the lack of HDR1, EOF1, EOV labels. This has worked well enough for at least 12 years of successful Disaster Recovery exercises. The only problem I have hit is remembering t o IPL the tape drive twice to get to my standalone DDR program that leads m y sysres backup.
With 3590 tapes and being able to stack multiple backups on a single tape it would be nice if DDR understood REAL standard labels. /Tom Kern On Wed, 7 Jun 2006 16:28:35 -0400, George Haddad <[EMAIL PROTECTED]> wrote: >I would like to DDR DUMP to standard label (3480-XF) tapes. >For reasons I won't go into here, I plan to "manually" define the >extents to be dumped to each tape, so DDR's multi-volume tape handling >is not an issue. >So is there any more to it than writing a VOL1 hdr, starting at the load >point, then doing the DDR dump with a SKIP 1 on OUTPUT? > >For example, in a CMS environment, would this be correct ? > >1) Write a VOL1 label to the tape > TAPE WVOL1 volser userid (XF > TAPE WTM 2 > >2) Boot a Standalone DDR > >3) Mount the tape labeled in Step 1 > >4) DDR dump: > INPUT nnnn 3390 volser > OUTPUT mmmm 3480 (SKIP 1 MODE XF > SYSPRINT CONS > DUMP start-cyl TO end-cyl > >Is the WTM needed after the WVOL1 to mark the end-of-tape? > >Does writing a VOL1 header w/o HDR1 cause any problems? > >Is it really this straightforward? > >Any gotchas I should be aware of (other than multi-tape DDR dumps, which >as I said, won't be an issue in my case)? >======================== ========================= ========================
