HP Matrix Operating Environment Software - Manual (Page 26)

NOTE: Matrix recovery management does not perform DNS updates or update the IP configuration
of logical servers associated with IO services during a failover operation. Your Network
Administrator is responsible for making the necessary modifications to ensure that network services
are available if you configure a logical server to use a different IP address or subnet at each site
in the Matrix recovery management configuration. Thus, Matrix recovery management does not
alter the IP address in the NIC in the OS to match that. You must modify the IP address of the OS
manually. For example, if the IP address of the VM at the primary site is configured to 10.10.10.1,
but the DR site subnet is 12.12.12.0, Matrix IO allocates 12.12.12.X IP address to the replica
service. But when the OS boots, you must manually configure the IP address of the NIC to
12.12.12.X, as its primary IP address still refers to 10.10.10.X.
