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. -----Original Message----- From: IBM Mainframe Discussion List [mailto:[email protected]] On Behalf Of Hal Merritt Sent: Thursday, June 10, 2010 10:49 AM To: [email protected] Subject: Re: How to create a new system from a existing system 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. -----Original Message----- From: IBM Mainframe Discussion List [mailto:[email protected]] On Behalf Of ibmnew Sent: Wednesday, June 09, 2010 10:47 PM To: [email protected] 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 VTAM&TCP/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!
