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 group(s). Then, use this procedure to remove the node from the failover group(s).

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.

   # scrgadm -c -g failover-resource-group -h nodelist

   -c

   Changes a resource group.

   -g failover-resource-group

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

   -h nodelist

   Specifies a comma-separated list of nodes that can master this resource group.

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

   # scrgadm -pvv -g failover-resource-group | grep -i netiflist

   ---

   Note -

   The output of the preceding command line identifies the nodes by node ID.

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 NAFO groups here. Also, you must input nodes to netiflist by node ID. Run the command line scconf -pv | grep "Node ID" to find the node ID.

   # scrgadm -c -j network-resource -x netiflist=netiflist

   -c

   Changes a network resource.

   -j network-resource

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

   -x netiflist=netiflist

   Specifies a comma-separated list that identifies the NAFO groups on each node. Each element in netiflist must be in the form of NAFO-group-name@nodeid.

4. Verify the updated information.

   # scrgadm -pvv -g failover-resource-group | grep -i nodelist # scrgadm -pvv -g failover-resource-group | grep -i netiflist
