It doesn't really matter, other than how the ipl failure message is
displayed. On bare metal, at least on our 9672 vintage machine (7060-H55),
ipling on bare metal will make the HMC screen turn red. On 2nd level, you
see the IPL unit failure message on the screen. Our D/R dumps are done on
MVS using ADRDSSU, so I end up ipling 5 times to get to the S/A ICKDSF and
then another 7 times to get to the S/A ADRDSSU program. The ipl failures
are the VOL label, the HDR labels, I guess the EOF label.

How do you IPL the tape? Bare metal or 2nd level?

Subject: Re: DDR to standard labeled tapes
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.
