How to Remove a Node From a Failover Resource Group

Perform the following steps to remove a node from a failover resource group.

If you plan to remove a node from all of the resource groups, and you use a scalable services configuration, first remove the node from the scalable resource groups. Then use this procedure to remove the node from the failover groups.

If the failover resource group contains shared address resources that scalable services use, see How to Remove a Node From a Failover Resource Group That Contains Shared Address Resources.

1. Update the node list to include all of the nodes that can now master this resource group.

   This step removes the node and overwrites the previous value of the node list. Be sure to include all of the nodes that can master the resource group here.

   # clresourcegroup set [-n node-zone-list] failover-resource-group

   -n node-zone-list

   Specifies a comma-separated, ordered list of nodes that can master this resource group. This resource group is switched offline on all 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 Nodelist property is set to all nodes in the cluster.

   failover-resource-group

   Specifies the name of the resource group from which the node is being removed.

2. Display the current list of IPMP groups that are configured for each resource in the resource group.

   # clresourcegroup show -v failover-resource-group | grep -i netiflist

3. Update netiflist for network resources that the removal of the node affects.

   This step overwrites the previous value of netiflist. Be sure to include all of the IPMP groups here.

   # clresource set -p netiflist=netiflist network-resource

   ---

   Note –

   The output of the preceding command line identifies the nodes by node name. Run the command line clnode show -v | grep -i “Node ID” to find the node ID.

   ---

   -p netiflist=netiflist

   Specifies a comma-separated list that identifies the IPMP groups that are on each node. Each element in netiflist must be in the form of netif@node. netif can be given as an IPMP group name, such as sc_ipmp0. The node can be identified by the node name or node ID, such as sc_ipmp0@1 or sc_ipmp@phys-schost-1.

   network-resource

   Specifies the name of the network resource that is hosted on the netiflist entries.

   ---

   Note –

   Sun Cluster does not support the use of the adapter name for netif.

4. Verify the updated information.

   # clresourcegroup show -vfailover-resource-group | grep -i nodelist # clresourcegroup show -vfailover-resource-group | grep -i netiflist
