HP General IO Connectivity manual Example Remote Failover with Local Failover support

Configuration

Configuring the High Availability Feature for X.25 over LLC2

NOTE		In the event of a failover, the XOL_floating_macaddr is moved from the
		Primary LAN card to the standby LAN card. HP recommends that you
		use the primary and standby LAN cards only for the XOL links
		configured with HA feature.
Step	3. Configure the SG package. For information on achieving remote failover
		functionality, see “XOL Package Definition” on page 92.
		For remote failover with local failover support, define the XOL package
		with the following changes:

•In the Start script of the package, stop the monitor if it is running. For details, see Example 3-6 on page 93.

•In the XOL package definition, use x25HAmonitor command instead of x25ifstate as the service command, as follows:

x25HAmonitor -c /etc/x25/x25config_llc2 -L /etc/x25/llc2_conf_def -m

NOTE		The x25HAmonitor command helps in failover of the XOL interface
		between the primary and standby LAN cards (on the local system), if the
		LAN card (either primary or standby) on which the XOL interface was
		active fails. The x25HAmonitor exits if it is does not start the XOL
		interface on the local system on either the primary or standby LAN card.
		The SG does a package failover to the standby node configured in the SG
		cluster.
Step	4. To start the SG package, run the following command
		cmrunpkg -v <package name>
Example 3-8		Remote Failover with Local Failover support
		The following two entries must be added to the LLC2 configuration file:
standby_device lan2			# lan2 is standby LAN.

XOL_floating_macaddr 0x0060B0A4EBE5 # Unique MAC address in the subnet

The SG package file that contains the X.25 commands is /etc./cmcluster/pkg*/control.sh file (one per XOL package).
