Bringing Resource Groups Online

To enable resources to begin providing HA services, you must enable the resources in the resource group, enable the resource monitors, make the resource group managed, and bring the resource group online. You can perform these tasks individually or by using the following one-step procedure. See the scswitch(1M) man page for details.

Perform this procedure from any cluster node.

How to Bring a Resource Group Online

1. Become superuser on a cluster member.

2. Enable the resource, and bring the resource group online.

   If the resource monitor has been previously disabled, it will be enabled also.

   # scswitch -Z -g resource-group

   -Z

   Brings a resource group online by first enabling its resources and fault monitors.

   -g resource-group

   Specifies the name of the resource group to bring online. The group must be an existing resource group.

3. Verify that the resource is online.

   Run the following command on any cluster node, and look for the resource group state field to see if the resource group is online on the nodes specified in the node list.

   # scstat -g

Example - Bring a Resource Group Online

This example shows how to bring a resource group (resource-group-1) online and verify its status.

# scswitch -Z -g resource-group-1
# scstat -g

Where to Go From Here

After a resource group has been brought online, the resource group is configured and ready to use. If a resource or node fails, the RGM maintains availability of the resource group by automatically switching the resource group online on alternate nodes.
