After the hosts are added to the KSYS, identify the hosts that must be paired across the
active site and the backup site. Each backup host in the host pair must meet all the resource
requirements so that the backup host can run the same workload in a disaster or a potential disaster
situation. The host pairing is applicable to only symmetric host groups (mxn_pairing=no). It's not
applicable to asymmetric host groups.
To pair the hosts across the sites in the VM Recovery Manager DR solution, complete the
following steps in the KSYS LPAR:
-
Pair the identified host (for example, host name:
Site1_host1) in the active site to the identified host (for example, host name:
Site2_host1) in the backup site by running the following command:
ksysmgr pair host Site1_host1 pair=Site2_host1
-
Repeat Step 1 for all the host pairs that
you want to create.
-
Optional: Verify the host pair that you created by running the following command:
ksysmgr query host
