Adding a node to the clustered system by using the CLI

You can use the command-line interface (CLI) to add a node back into the system after it is either removed or rejected.

To add a node to a system, complete the following procedure:

1. Issue this CLI command to list the node candidates:

   lsnodecandidate

2. Issue this CLI command to add the node:

   addnode -panelname panel_name -name new_name_arg -iogrp iogroup_name

   The panel_name variable is the name that is noted in step 1. (For this example, the panel name is 000279.) The number is printed on the front panel of the node that you are adding back into the system. Use the new_name_arg variable to specify a name for the new node. The iogroup_name variable is the I/O group that was noted when the previous node was deleted from the system.

   Note: In a service situation, add a node back into a system by using the original node name. When the partner node in the I/O group is not deleted, the I/O group name is the default when the -name value is not specified.

   This example shows the command that you can use: addnode -panelname 000279 -name newnode -iogrp io_grp1

   The following example output might result:

   Node, id [newnode], successfully added

   Attention: If more than one candidate node exists, add it into same I/O group to which it belonged before it was deleted. Failure to do so might result in data corruption. If you are uncertain about which candidate node belongs to the I/O group, shut down all host systems that access this system. Restart each system after you add all nodes back into the system.
3. Issue this CLI command to ensure that the node was added successfully:

   svcinfo lsnode
