X.25 Package Definition

An X.25 package is needed for each HA X.25 node. This package allows

HP MC/ServiceGuard to automatically:

• start the X.25 link (x25init command) when the X.25 package starts

• start a process (x25ifstate command) to monitor the state of the

X.25 link

• stop the failed X.25 package before migrating to a backup node

To define each X.25 package, you need:

Package Name:

to identify the X.25 package. Use a name such as

x25pkg1.

Service Name:

to monitor the X.25 link to be managed

Service Command:

1 2 ... 72 73 74 75 76 77 78 79 80 81 82 ... 260 261
