Managing Sysplexes with the same name

Edit online

Copy Services Manager allows multiple host connections to z/OS Sysplexes that have the same name. To use this feature, a CSV file can be used to give a user-defined name for the host connection or for the set of host connections. When the Sysplex name for a host connection is displayed, that was defined in the CSV file, Copy Services Manager displays the user-defined name. If multiple Sysplexes have the same name, define a unique user-defined name for each Sysplex. So that, when you associate a Sysplex to a particular session, the Sysplexes are distinguishable, which allows the user to select the correct Sysplex without renaming the Sysplex on z/OS.

About this task

Follow these steps to set Sysplexes with the same name:

Tip: Before you associate any session to a Sysplex, define the zosSysplexAlias.csv file. If sessions are already associated with host connections whose Sysplex ID is changed in the zosSysplexAlias.csv, for each of those sessions, open the session properties and disable HyperSwap or Hardened Freeze, wherever applicable before you add the host connection to the zosSysplexAlias file.

Procedure

  1. Define a file in csmServer > properties with a file name zosSysplexAlias.csv.
  2. For each host connection that is supposed to be given a different Sysplex name than the pre-defined name in the system, create a line with the following format: hostname:port,systemName,newSysplexID
    For example,
    hostname1.labs.ibm.com:5858, LOCAL1, ZOSID1
    hostname2.labs.ibm.com:5858, LOCAL2, ZOSID2
    hostname3.labs.ibm.com:5858, LOCAL3, ZOSID3
  3. Ensure that all host connections are added. (Refer Adding a host system connection)
  4. Restart the Copy Services Manager server.
  5. For each session that is associated with the changed sysplex ID, open the session properties and set the z/OS Sysplex Association to the correct Sysplex ID. Then, re-enable HyperSwap or Hardened Freeze as needed.
