This procedure upgrades configuration data on a cluster that already has configured resource groups, resource types, and resources. This procedure can also be used to generate a configuration template for resource groups, resource types, and resources.
In this procedure, the configuration data on cluster1 is upgraded to match the configuration data on cluster2.
Using the system administrator role, log on to any node in cluster1.
For example, node1.
The system administrator role gives you the following RBAC rights:
Retrieve the configuration data from the cluster by using the image file option of the scsnapshot tool:
node1% scsnapshot -s scriptfile1 -o imagefile1
When run on node1, the scsnapshot tool generates a script that is called scriptfile1. The script stores configuration data for the resource groups, resource types, and resources in an image file that is called imagefile1. For more information about using the scsnapshot tool, see the scsnapshot(1M) man page.
node2 % scsnapshot -s scriptfile2 -o imagefile2
On node1, generate a script to upgrade the configuration data on cluster1 with configuration data from cluster2:
node1 % scsnapshot -s scriptfile3 imagefile1 imagefile2
Edit the script that you generated in Step 4 to adapt it to the specific features of the cluster1, and to remove data specific to cluster2.
From node1, launch the script to upgrade the configuration data.
The script compares the characteristics of the local cluster to the cluster where the script was generated. If the characteristics are not the same, the script writes an error and ends. A message asks whether you want to rerun the script, using the -f option. The -f option forces the script to run, despite any difference in characteristics. If you use the -f option, ensure that you do not create inconsistencies in your cluster.
The script verifies that the Sun Cluster resource type exists on the local cluster. If the resource type does not exist on the local cluster, the script writes an error and ends. A message asks whether you want to install the missing resource type before running the script again.
