1. End the cluster resource group to configure replication to the next node. For example: ENDCRG CRG(GEOCRG)

2. Use the Configure Geographic Mirroring (CFGGEOMIR) command to configure Geographic Mirroring replication to the additional node. For this example, the following command is used:

   Code Block
   CFGGEOMIR ASPDEV(MYIASP) ACTION(*CREATE) DELIVERY(*ASYNC) COMPRESS(*RESYNC) TGTNODE(WI01)

   This command configures Geographic Mirroring for the IASP named MYIASP to the node WI01.
   Since WI01 is in a different site from the production system and is the lowest numbered node at that site, it is possible to specify asynchronous delivery, enabling further distances between the nodes.

3. Since *SELECT was specified for the disk units, a panel showing all non-configured units is displayed on the target node. Use option 1 to select the disk units you want from the list.
   After confirming the selection, PowerHA will initialize and format the disk units on the target system and configure Geographic Mirroring.
   Since the default value for the start indicator parameter was left as *YES in the command, PowerHA will also start do the following:

   1. Start the cluster resource group

   2. While the production copy did not need to be varied off, if it had been varied off, the start parameter value of *YES will also vary on the IASP on the production system

   if it was not already varied on, and start replication

   1. .

4. This example would repeat this process starting at step 1 for the final node WI02. With WI02, a delivery value of *SYNC must be specified since synchronous replication will be used between the systems within the IA site containing nodes WI01 and WI02.
