I'm not sure this is that much of an issue anymore.

Years ago, in a prior life, probably while running MVS/XA, our DR plan
called for allocating only one spool volume before the first IPL because the
format during the cold start took such a long time. After the IPL, we would
allocate the rest of the spool space and then let JES format it while we did
other things in parallel,

At our last DR test a few months ago, running z/OS 1.4, my notes show that
the cold start, which formatted three 3390-3 volumes, only took 2 minutes.

Simple question.

If I start JES2 with PARM='COLD,NOFMT' that will cold start the Checkpoint
and not format the Spool spaces.  Then after that finishes do I still need
to format the Spool Space or will just cold starting the Checkpoint be
sufficient?  Or does that then just push out the format of the spool spaces?
We are just doing full volume restores of our JES2 volumes so they will not
be allocated as new spaces.  They already exist.


We are trying to reduce the time our JES2 startup takes at DR and I forget
how the spool space is handled after the Cold start is completed on the
checkpoint.
