Hi Sreekanthtm,

Service Gurad is a cluster software , allows you to create high availability clusters of HP 9000 Series 800 computers. A high availability computer system allows application services to continue in spite of a hardware or software failure. Highly available systems protect users from software failures as well as from failure of a system processing unit (SPU), disk, or local area network (LAN) component. In the event that one component fails, the redundant component takes over. ServiceGuard and other high availability subsystems coordinate the transfer between components.

A ServiceGuard cluster is a networked grouping of HP 9000 series 800 servers (host systems known as nodes) having sufficient redundancy of software and hardware that a single point of failure will not significantly disrupt service. Application services (individual HP-UX processes) are grouped together in packages; in the event of a single service, node, network, or other resource failure, MC/ServiceGuard can automatically transfer control of the package to another node within the cluster, allowing services to remain available with minimal interruption.



Cheers,
Raj.

Shalom,

Serviceguard is a High Availability system environment. It takes two or more normally reliable systems and puts them into a configuration called a cluster which provides, when configured correctly very high availability service.

Hence the name, aka Serviceguard.

It is not fault tolerant and consists of software and configuration that can be purchased from Hewlet-Packard Corporation.

You are asking for a general explanation and now have it.

Here is a configuration doc with links in it to others:

sreekanth,

As the name says, it is the guard for service. that is used for High availability.
i know only little about service guard.
SG is a big topic for begineer.
