Ismael,
You can issue the mount command from another LPAR. If the other LPAR is
z/VM, this can be a VMTAPE MOUNT or DFSMSRM MOUNT command. If you have
only one z/VM LPAR, then you'll have to issue the mount from z/OS. I
don't know the command for that.
Another option is to have a small system on disk that can be used to
recover your main system. Normally, you would maintain the small system
as a guest of your main system, but you would configure it so that it
can also be IPLed first level. If you have to recover your main system
in its usual datacenter, just IPL the small system and start your
restores. For disaster recovery, you could backup and restore the small
system using full volume dumps from z/OS. Note that this works for
restores, but not standalone dump. For standalone dump, you need to have
another LPAR available to IPL the small system. If you IPL it in the
LPAR that you want to dump, the IPL will destroy the data that you want
to dump.

back to me.

Subject: [IBMVM] Stand-alone IPL of a Virtual tape
We are starting to implement a virtual tape system in our VM system;
they are planning to get rid of our silos. To us, it is a black box;
the zOS guys say "just mount these volumes on these tape devices; treat
them like real cartridge on real 3490 drives and you're good to go."
I've tested the volumes & devices using RMSMASTR, VMTAPE, VMBACKUP, DDR
and for the most part, they work well.
My question is:
Recovery process usually starts with a stand-alone program, like DSF or
DDR. If we have to IPL a stand-alone program like DDR that happens to be
in a virtual volume onto a bare LPAR, how is this done?
Thanks for any info.
Ismael
