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 Multi-node Package
If CFS/CVM is configured in the environment, the Cluster File System Multi-node Package needs
to be created.
To configure the Cluster File System 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 each 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.
To create a Metrocluster with two sites, run cmdeploycl. The cmdeploycl command and options
are described 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
To create a Metrocluster with two sites and have the SG-CFS-pkg System Multi-node package
(SMNP) configured in single step, run cmdeploycl as described in the follwing example:
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 manpage,
cmdeploycl (1m).
Setting up replication
In SADTA, the data of the complex workload must be replicated between the disk arrays at each
site. The Site Controller package uses the Metrocluster package attributes to prepare the storage
during its start up. For more information on configuring replication for Continuous HP P6000/EVA
disk Arrays in your environment, see “Setting up the replication” (page 16).
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 each site. The data of the complex
workload must be replicated between the disk arrays at each site.
