XOL Package Definition

An XOL SG package is required to configure a highly available XOL

interface on all nodes in the SG cluster. This package allows HP

MC/Service Guard to automatically:

• Assign a unique MAC address (using the lanadmin command) to the

LAN card in use.

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

starts.

• Run the command x25ifstate to monitor the state of the XOL

interface.

• Stop the XOL interface when the monitoring command detects a

failure.

To define the X.25 package, you require the following attributes:

Package Name Identifies the X.25 package, for example, xol_pkg1.

Service Name Monitors the XOL interface to be managed, for

example, xol_SG_service1

Service Command Monitors the XOL interface status, for example,

x25ifstate

To configure XOL remote failover, complete the following steps:

NOTE The XOL HA feature is enabled by default in HP-UX 11i v3.

Therefore, the -enableXOLHA option is no

longer required.
