Building Disaster Recovery Serviceguard Solutions Using Metrocluster with Continuous Access for P9000 and XP A.11.00

Figure 20 Applying the configuration
NOTE: Site controller package can also be created using the Package Easy Deployment feature
available in Serviceguard Manager version B.03.10. For more details, see Using Easy Deployment
in Serviceguard and Metrocluster Environments on HP-UX 11i v3 available at http://www.hp.com/
go/hpux-serviceguard-docs —> HP Serviceguard. In case of easy deployment, the Metrocluster
module parameters are auto-discovered.
Configuring Site Controller package using command line interface
This section describes the procedure to configure the Site Controller package in a Metrocluster
using command-line interface. The procedure consists of three steps:
1. “ Configuring an empty site controller package” (page 47)
2. “Configuring the Site Safety Latch dependencies for a complex workload” (page 48)
3. “Modifying Site Controller to manage complex workload” (page 49)
Configuring an empty site controller package
Following are the guidelines that you must follow while configuring an empty Site Controller
package:
• The default value of the priority parameter is set to no_priority. The Site Controller
Package must not be subjected to any movement because of package prioritization. So do
not change this default value.
• The default value of the failover_policy parameter for the Site Controller package is set
to site_preferred. Based on your requirement, you can set the value to
site_preferred_manual.
The site_preferred value implies that during a Site Controller package failover, while
selecting nodes from the list of the node_name entries, the Site Controller Package fails over
to the nodes that belong to the site of the node it last ran on, rather than the nodes that belong
