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

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
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. 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 both, the regular Metrocluster failover packages
and Site Controller 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, set the failover_policy parameter to site_preferred.
Easy deployment of Metrocluster
Starting with Serviceguard version A.11.20 Patch PHSS_41628, you can use the cmdeploycl
command to create a Metrocluster with sites configured in Serviceguard cluster configuration.
When you run the cmdeploycl command to create a cluster on nodes where Metrocluster is
installed, the system throws a warning in case a quorum server is not specified in its list of arguments.
The cmdeploycl command and options are described below:
cmdeploycl [-t] [-s site ]... [-n node]... [-N net_template ] [-c
clustername] [-q qs_host [qs_ip] | -L locklun] [-cfs]
For Example, to create a two site cluster with nodes n1, n2, n3,and n4, run the following command:
# cmdeploycl -s siteA -n n1 -n n2 -s siteB -n n3 -n n4 -q qs.quorum.com
Setting up the replication
The following procedures will prepare Serviceguard cluster for use with Continuous Access P9000
or XP data replication in a Metrocluster.
