High availability requires:
Two homogenous, network systems with similar configurations in terms of resources such as CPU, memory, and so on
The high availability package and the associated hardware
Devices that are accessible to both nodes
A logical volume manager (LVM) to maintain unique device path names across the cluster nodes
Volumes or disk suite objects on the multi host disks
Third-party vendor mirroring for media failure protection
Logical host name or floating IP address that can be bound to any of the primary and secondary nodes
For more information about requirements for running Sun Cluster, see the Sun Cluster documentation.
See your hardware and operating system documentation for information about installing platform-specific high availability software.
