I have actually done the creation of a new system using EMC utilities to mirror
and then split off complete copies of DASD a few times.
There are some significant problems with doing that, most notably dealing with
duplicate volumes and setting up networking prior to splitting the volumes. It
can be pretty hazardous when IPLing and responding with the right unit
addresses with all of the volumes. Sometimes the operators have forgotten that
you answer the one that you want kept OFFLINE, instead of what you want on. It
can make for some pretty interesting clean up after a mistake like that is made.

Some replicate the system volumes proper, and keep the 'personality' stuff
(parmlibs, tcpparms, mcats, etc) separate. IODF's, for example, can be shared
(note that they should be cataloged to each system for dynamic changes).
Some used shared, concatenated parmlibs to keep the image specific stuff in one
and the common stuff in another.
There's some excellent RedBooks on the subject as well as the ABC's of System
Programming series.

Subject: How to create a new system from a existing system
Dear all
As we know,if we want to create a new system from a existing system,we usually
clone the existing system.
When we clone the existing system,we could use a new name convention for the
new system.for example :
a new syslex name,a new system,a new MCAT name. but it take few days to do
it.
I wonder whether I could create a new system by coping all volumes on the
exsiting system by full volume copy
command with volid;then could I change the syslex name or system name? I feel
it faster than clone.
Of course we need do something as the following examples:
For example:
Because there are duplex volumes,we need offline some of them from one
system.because there is a new CF
for the new system,we need redefine the CFRM.We aslo need modify VTAMTCP/IP
definition..
Are there any other considerations we should pay attention to when we create
the system by coping all volumes?
Any Suggestions are highly appreciated!
Thanks a lot!
Best Regards,
Jason Cai
