Re: DDR to standard labeled tapes

So IPLing the tape 5 times (or 7 times) is a cumbersome way of doing a FSF.
What happens when you IPL a HDR1, you get some kind of error right? The tape
at that point has positioned itself at the next file and you do the process over again.
We've been trying to decide if we want to use STD Labels on our SYSRES back up
tape. IPL'ing a tape 2nd level is really not an issue because you have an FSF command
available. But when IPL'ing from the HMC a.k.a. bare metal then you don't have an FSF command.
To deal with that situation, you just IPL the tape x-number of times until you get to the file you need, right?

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.
