How to Add a Node to a Failover Resource Group

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

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

   ---

   Note -

   The output of the command line for nodelist identifies the nodes by node name. The output for netiflist identifies the nodes by node ID.

   ---

2. Update netiflist for the network resources that the node addition affects.

   This step overwrites the previous value of netiflist, and therefore you must include all of the NAFO groups here. Also, you must input nodes to netiflist by node ID. To find the node ID, use scconf -pv | grep "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 (logical hostname or shared address) that is being 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.

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

   This step overwrites the previous value of nodelist, and therefore you must include all of the nodes that can master the resource group here.

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

   -c

   Changes a resource group.

   -g resource-group

   Specifies the name of the resource group to which the node is being added.

   -h nodelist

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

4. Verify the updated information.

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