Recovering a node and returning it to the system using the CLI

After a node or an I/O group fails, you can use the command-line interface (CLI) to recover a node and return it to the system.

Complete the following steps to recover a node and return it to the system:

  1. Run the lsnodecanister command to verify that the node is offline.
  2. Run the rmnodecanisterNode_ID command on the system to remove the old instance of the offline node from the system..
  3. Run the lsnodecandidate command to verify that the node is visible on the fabric.
  4. Run the addnode -wwnodenameWWNN-iogrpIOgroupname/ID-nameNodeName command to add the node back into the system, where WWNN is the worldwide node name, IOgroupname/ID is the I/O group name or ID, and NodeName is the name of the node.
    Note: In a service situation, a node must be added back into a system using the original node name. If the partner node in the I/O group has not also been deleted, this is the default name that is used if the -name parameter is not specified.
  5. Run the lsnodecanister command to verify that the node is online.
