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:
Step	1.	To enable XOL HA feature for the system, run the following command:
		x25init -enableXOLHA
NOTE		HA feature must be enabled on all the nodes configured in the SG
		cluster.
Step	2.	Configure the SG package. For the sample SG control scripts to achieve
		remote failover functionality. See “XOL Package Definition” on page 92.
Step	3.	To start the SG package, run the following command:
		cmrunpkg -v <package name>
