Building Disaster Recovery Serviceguard Solutions Using Metrocluster with 3PAR Remote Copy for Linux B.01.00.10, December 2013

For the failover_policy parameter, in Metrocluster failover packages you can use any

of the Serviceguard defined failover policies. The site_preferred and

site_preferred_manual failover policies are introduced in Serviceguard specifically for

Metrocluster configurations.

The site_preferred value implies that when a Metrocluster package needs to fail over, it

fails over to a node in the same site as the node it last ran. If a configured node is not available

within the same site, the package fails over to a node on another site.

The site_preferred_manual failover policy enables automatic failover of packages within

a site and manual failover across sites.

Configure a cluster with sites to use either of these policies. For information on configuring

the failover policy to site_preferred or site_preferred_manual, see “Site Aware

Failover Configuration” (page 10).

3. Validate the package configuration file.

# cmcheckconf -P pkgName.config

4. Apply the package configuration file.

# cmapplyconf -P pkgName.config

NOTE: After the modular Metrocluster 3PAR package is created, if the value of any

Metrocluster 3PAR parameter needs to be changed, then edit this package configuration file

and re-apply it.

Configuring a Metrocluster package using Serviceguard Manager

To configure a Metrocluster package using Serviceguard Manager:

1. Access one of the node’s System Management Home Page at http://<nodename>:2301.

2. Click Tools. If Serviceguard is installed, one of the widgets will have Serviceguard as an

option. Click Serviceguard Manager; link within the widget.

3. On the Cluster’s Home Page, click the Configuration Tab, and then select Create A Modular

Package option.
