Indrajit,

ServiceGuard is a High Availability (HA) application. It is used in conjunction with other HA techniques to produce a loosely coupled cluster. An application running on a primary system is run on a backup system should a failure or other switch over condition exist on the primary system. ServiceGuard can detect failures of a CPU, LAN, application, and other components.

All of the systems as well as all of the application packages have IP addresses. When a failure occurs the backup system runs the high availability package and the IP address of the package moves with the package to the backup system. If only a LAN card fails in a primary system ServiceGuard will fail over to a standby LAN card rather than the backup system.

You can have many systems in a ServiceGuard cluster, all of which can be active. You don't need to have systems in a standby state waiting for a failure to occur.

http://docs.hp.com/en/ha
and/or take a training course

Bhagat,

Also , remember one important thing, in serviceguard environment , you should make AUTO_VG_ACTIVATE=0 (default 1) , in /etc/lvmrc, and define local vgs under custom_vg_activation script.

Enjoy,
Cheers,
Raj.

hi

you can go for trg with hp.

that is also to good.before that attend SNA-3 ( overview of the HA)

[Khashru]

Service Guard is a HA solution from Hp without making expensive hardware fault tolerance. You will find lots of document in the net for that.

Concept is it will monitioor application and hardware according to the logic supplied and if anything goes wrong it will do the action specified in the configuration.
