I have some spare cylinders on my sysres volume defined, formatted and used as SPOL, PAGE and TDSK. These areas are not in the standard System Configuration, but in a Standalone configuration. At the DR site, I have restored the sysres volume, IPLed the sysres using the SA Config and then use execs and service VMs to restore the rest of the system and then perform a final IPL to bring up the Production Config. At one time, the MVS team was running the DR vendor's floor MVS system under my SA system while I restored VM.
There is a DCSSBKUP/DCSSRSAV set of programs that can backup DCSSes to disk and restore them to spool. I have also used another utility from a vendor (I cannot remember their name at this time), and that utility was given to me free of charge. The other mechanism to save/restore DCSS/NSS is to use SPXTAPE DUMP SDF ALL to a virtual tape drive (VTS), rewind it and copy the data to disk (I use an AWS utility) and then backup that DASD. At the DR site, restore that DASD, copy the data back to a virtual tape and use SPXTAPE LOAD SDF ALL from the virtual tape drive. Feel free to call me to talk about any of this. /Tom Kern /On contract to US Dept of Energy /301-903-2211 On 8/9/2011 08:03, Crabtree, Anne D wrote: > I currently back up all my z/vm packs (res,page,spool) via an adrdssu job on > z/os each > Sunday.
