The HP XC system offers improved availability, which enables the HP XC System Software to interact with optional Availability tools, such as HP Serviceguard. These tools are optional: you must order them from the manufacturer and install them according to the manufacturer's prescribed installation procedure. The availability tools are located in a directory that the manufacturer chooses.
Improved availability provides for the failover of configured services from a failed node to another configured in the HP XC system.
For more information on improved availability, see Chapter 2.
