In our environment we have four CECs. 1 - CF only 3 - running z/OS & z/VM - three different sysplexs
We have one parallel sysplex that crosses all three CECs, the other two base sysplex each one a different CEC. We have several DASD volumes that are setup for limited sharing across all three sysplexs. I say limited because we can’t share the GRS environment across the different sysplex. We do device reserves for a limited enqueue setup. With all that said I will use DFDSS to copy the IODF to the shared DASD and then do a DFDSS restore on the other systems. We use the same IODF name across all the lpars. We do data replication to our DR environment so the new IODF gets to DR by default. Before the shared DASD setup I would have FTP the DFDSS copied file to the other lpars and then do the restore. I don't know if this qualifies as best practice, but this is how I move the IODF around. Thanks..

PROD CEC 2 : Two LPARs Z/OS CF CEC any z/OS lpars? No TEST CEC: Three LPARs, one ICF, two Z/OS DR CEC how many lpars? Two ICF one TEST, one PROD- Three Z/OS one TEST and two PROD. Do the lpars share DASD? Yes all of them sharing two DASD in both HO and DR. Are the lpars in a SYSPLEX? two SYSPLEX one for TEST includes all TEST LPARS in both Sites. One SYSPLEX for all PROD LPARs in the two sites. How do you update the DR DASD? via PPRC Do you have real time replication? Yes Thanks Mohamed Gomaa From: "Field, Alan" <alan.fi...@bluecrossmn.com> To: IBM-MAIN@LISTSERV.UA.EDU Sent: Sunday, January 15, 2017 1:18 PM Subject: Re: The best practice of IODF in big system Mohamed, more questions: PROD CEC 1 how many lpars PROD CEC 2 how many lpars CF CEC any z/OS lpars?
