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.
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
Changes a resource group
Specifies the name of the resource group from which the node is being removed
Specifies a comma-separated list of the names of the nodes that can master this resource group
Display the current list of IP Networking Multipathing groups that are configured for each resource in the resource group.
# scrgadm -pvv -g failover-resource-group | grep -i netiflist
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 IP Networking Multipathing groups here.
# scrgadm -c -j network-resource -x netiflist=netiflist
The output of the preceding command line identifies the nodes by node name. Run the command line scconf -pv | grep “Node ID” to find the node ID.
Changes a network resource.
Specifies the name of the network resource that is hosted on the netiflist entries.
Specifies a comma-separated list that identifies the IP Networking Multipathing groups that are on each node. Each element in netiflist must be in the form of netif@node. netif can be given as an IP Networking Multipathing 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.
Sun Cluster does not support the use of the adapter name for netif.
Verify the updated information.
