9.4 Cluster Migrating Resources to Different Nodes

You can migrate cluster resources to different servers in your cluster without waiting for a failure to occur. You might want to migrate resources to lessen the load on a specific server, to free up a server so it can be brought down for scheduled maintenance, or to increase the performance of the resource or application by putting it on a faster machine.

Migrating resources lets you balance the load and evenly distribute applications among the servers in your cluster.

Using iManager

  1. In iManager, click Clusters, then click Cluster Manager.

  2. Browse to locate and select the Cluster object of the cluster you want to manage.

  3. Select the check box next to the resource you want to migrate and click Migrate.

    A page appears, displaying a list of possible servers that you can migrate this resource to.

  4. Select a server from the list to migrate the resource to, then click OK to migrate the resource to the selected server.

Using Console Commands

  1. As the root user, enter the following at the console command prompt of a cluster node:
