3. Run the cmapplyconf command to apply the configuration file.
4. Run the cmruncl command to start the cluster.
After the cluster is started, you can run the cmviewcl command to view the site configuration.
Configuring the Cluster File System (CFS) multi-node package
If CFS/CVM is configured in the environment, then the CFS multi-node package must be created.
To configure the CFS multi-node package when using HP Serviceguard Storage Management Suite:
1. Run the cfscluster command to create an SG-CFS SMNP package.
After creating the package, ensure that there are two CFS sub-clusters in the Metrocluster.
2. Run the cfscluster status command on any node at both sites to view the list of nodes
and the status of every node.
Easy deployment of Site-Aware cluster and CFS cluster using cmdeploycl
You can use the Cluster Easy Deployment feature while creating the cluster for the first time.
In order to create a Metrocluster with two sites, run the cmdeployclcommand. The cmdeploycl
command and options are as follows:
cmdeploycl [-t] [-s site ]... [-n node]... [-N net_template ] [-c
clustername] [-q qs_host [qs_ip] | -L locklun] [-cfs]
For Example,
# cmdeploycl -s siteA -n node1 -n node2 -s siteB -n node3 -n node4 -c
site_cluster -q quorum.server.com
In order to create a Metrocluster with two sites and have the SG-CFS-pkg System Multi-node package
(SMNP) configured in one step, run the cmdeploycl command.
For Example,
# cmdeploycl -s siteA -n node1 -n node2 -s siteB -n node3 -n node4 -c
site_cluster -q quorum.server.com -cfs
This creates a cluster with two sites with the CVM infrastructure configured via the SG-CFS-pkg
System Multi-node (SMNP) package. For additional information on cmdeploycl, see its manpage,
cmdeploycl (1m).
Setting up replication
In SADTA, the data of the complex workload must be replicated between the disk arrays at every
site. The Site Controller package uses the Metrocluster package attributes to prepare the storage
during its start up. For more information about configuring replication for P9000 or XP Disk Arrays
in your environment, see “Setting up the replication” (page 19).
Setting up the complex workload redundantly in Metrocluster
For SADTA, the complex workload is configured redundantly in the cluster. A separate set of
packages must be used to configure the complex workload at every site. The data of the complex
workload must be replicated between the disk arrays at every site.
