Combination of Physical Hosts and Virtual Environments
In Figure 23, the Serviceguard cluster is composed of both virtual HP Integrity VM guests and hosts.
The cluster is configured between Host1_VM1, Host2_VM2, Host3_VM3(VM guests), and physical
host4. Applications can either be failed over to a HPVM guest or a physical host. Similarly, vPars
can be configured instead of HPVM guests.
