If you don't need to run the alternate volume for long, you can live with a 1 volume (3390-9) RES pack, with spool and page on it. I built one to be able to IPL something other than our production systems and use multiple VMs in that system to COPY our DASD (VM and MVS) from one DASD subsystem to another. Later I even used a copy of that to do some DDR restores on a very separate system.
My current RES pack even has an alternate CONFIG file that uses areas on the production RES pack for PAGE & SPOOL for a Disaster Recovery scenario. /Tom Kern /on contract to US Dept of Energy /301-903-2211 (Office) /301-905-6427 (Mobile) On 8/2/2012 09:01, Collinson.Shannon wrote: > In z/VM 5.4, we had two set of packs (a set consisting of a "res" pack with > the code on it + a spool + a page volume) that we'd alternate between as we > brought up different levels of maintenance.
