Building Disaster Recovery Serviceguard Solutions Using Metrocluster with Continuous Access XP P9000 for Linux B.01.00.00

Site Aware Failover Configuration
Serviceguard cluster allows sites to be configured in a Metrocluster environment. The Serviceguard
cluster configuration file includes the following attributes shown in Table 1 (page 15) to define
sites. This enables to use the package failover policies site_preferred_manual or
site_preferred for Metrocluster package.
Table 1 Site Aware Failover Configuration
DescriptionAttributes
To define a unique name for a site in the cluster.SITE_NAME
SITE keyword under the node's NODE_NAME definition.SITE
The following is a sample of the site definition in a Serviceguard cluster configuration file:
SITE_NAME san_francisco
SITE_NAME san_jose
NODE_NAME SFO_1
SITE san_francisco
.....
NODE_NAME SFO_2
SITE san_francisco
........
NODE_NAME SJC_1
SITE san_jose
.......
NODE_NAME SJC_2
SITE san_jose
........
Use cmviewcl command to view the list of sites that are configured in the cluster and their
associated nodes. The following is a sample of the command, and the output:
# cmviewcl -l node
SITE_NAME san_francisco
NODE STATUS STATE
SFO_1 up running
SFO_2 up running
.........
SITE_NAME san_jose
NODE STATUS STATE
SJC_1 up running
SJC_2 up running
You can configure either of these failover policies for Metrocluster failover packages. To use these
policies, you must specify site_preferred or site_preferred_manual for the failover_policy
attribute in the Metrocluster package configuration file.
NOTE: For a Metrocluster package, HP recommends that you set the failover_policy
parameter to site_preferred.
Setting up the replication
The following procedures will prepare Serviceguard cluster for use with Continuous Access XP or
P9000 data replication in a Metrocluster.
