Re: CMS/PDF
We have 2 LPARs in our environment. One is z/VM, the other is z/OS. Our
requirement is to build connection between z/Linux running on z/VM and z/OS
system.
Therefore, I defined a new IQD type channel(E0 5000-5031) in IODF. The
directory definition for z/Linux is:
NSSes (e.g. CMS, CMSFILES, CMSPIPES, and may more) can easily be backed up
using SPXTAPE to write them to tape (preferably every night).
Thus the restore at DR is pretty simple (as long as you are very careful to
send a copy of the tapes off-site, along with a hardcopy listing of which NSS

The same way as E0? Then in Linux you can “bond” the two interfaces, which
will provide either load balancing or hot standby.

Not that you need the page packs to be able to IPL z/VM at the DR site.
But, as you use adrdssu on z/OS to restore the z/VM packs, you could start
some jobs on z/OS to run ICKDSF CPVOL FORMAT ... RANGE(0,xxx) TYPE(PAGE,
1,xxx).
I guess that should work as ICKDSF is supposed to be the same on z/OS,
Don’t know too much about the z/OS side, but my educated guess is NO.

In a real disaster, you don't have a system's programmer.

Hi Anne,
Our DR restores are done under a VM system that is available at the DR
site. We include a spool offload tape (actually 2 of them, one for
spare) with the NSS backups on it and a few PUN files on the same
tape. One of those PUN files is the DSF commands necessary to format
page and spool,
We backup cyl 0 (zero) of the page packs just to avoid having to run
ICKDSF to put a label on the packs. We then, of course, restore that
cyl 0 at DR.

Don't you still need to format 1-END? In my experience, you can end up
with paging errors if the dasd isn't initialized/formatted. Haven't tried
just cylinder 0 though, so I could be wrong..

You will need spool space, so you might as well copy it (or keep a small spool
area available only with the NSS files, JUST for DR).
Time to resubmit that requirement for disk support for SPXTAPE.

No need, 0-END (or 1-END) is not mandatory.
You can use only pieces of dasd for each type, but all referenced in

A clearer way of saying this might be “you only need to CPFMTXA the cylinders
