Perform this procedure from any cluster node.
Ensure that the following conditions are met:
You have the following information:
The name of the resource group that you are switching over
The names of the nodes where the resource group is to be brought online or to remain online
The nodes where the resource group is to be brought online or to remain online are in the cluster.
These nodes have been set up to be potential masters of the resource group that you are switching.
To see a list of potential primaries for the resource group, type the following command:
# clresourcegroup show -v
On a cluster member, become superuser or assume a role that provides solaris.cluster.modify RBAC authorization.
Switch the resource group to a new set of primaries.
# clresourcegroup switch [-n node-zone-list] resource-group
Specifies a comma-separated, ordered list of global-cluster non-voting nodes that can master this resource group. The resource group is switched offline on all of the other nodes. The format of each entry in the list is node:zone. In this format, node specifies the node name and zone specifies the name of a global-cluster non-voting node. To specify the global-cluster voting node, or to specify a node without global-cluster non-voting nodes, specify only node.
This list is optional. If you omit this list, the resource group is switched on all nodes in the resource group's node list.
Specifies the name of the resource group to switch.
If any resource group that you are switching declares a strong affinity for other resource groups, the attempt to switch might fail or be delegated. For more information, see Distributing Online Resource Groups Among Cluster Nodes.
Verify that the resource group has been switched to the new primary.
The output from this command indicates the state of the resource group that has been switched over.
# clresourcegroup status
This example shows how to switch the resource group resource-group-1 from its current primary phys-schost-1 to the potential primary phys-schost-2.
To verify that the resource group is online on phys-schost-1, the following command is run:
phys-schost-1# clresourcegroup status === Cluster Resource Groups === Group Name Node Name Suspended Status ---------- --------- --------- ------ resource-group1 phys-schost-1 No Online phys-schost-2 No Offline
To perform the switch, the following command is run:
phys-schost-1# clresourcegroup switch -n phys-schost-2 resource-group-1
To verify that the group is switched to be online on phys-schost-2, the following command is run:
phys-schost-1# clresourcegroup status === Cluster Resource Groups === Group Name Node Name Suspended Status ---------- --------- --------- ------ resource-group1 phys-schost-1 No Offline phys-schost-2 No Online
