Verify LUN reporting nodes after moving a volume

Contributors netapp-mwallis

You can add LUN reporting nodes to help maintain optimized LUN paths.

If the volume that you move contains LUNs, and the destination aggregate is on another high-availability (HA) pair, ONTAP automatically adds an HA pair to the Selective LUN Map reporting-nodes list

Before you begin

Two LIFs must be configured: one LIF on the destination node and the other LIF on the HA partner of the destination node.

About this task

This procedure is required only if you move a volume from one HA pair to a different HA pair. If you move a volume to a different node of the same HA pair—​for example, if you have a two-node cluster or a MetroCluster configuration—​you can skip this procedure.

Steps

  1. Verify that the destination node and its partner node are in the reporting-nodes list of the volume. If the nodes are not in the reporting-nodes list, add the destination node and its partner node to the reporting-nodes list of the volume:

    lun mapping add-reporting-nodes

  2. Rescan from the host to discover the newly added paths.

  3. Add the new paths to your MPIO configuration.

  4. Remove the previous LUN owner and its partner node from the reporting-nodes list:

    lun mapping remove-reporting-nodes -remote-nodes -vserver vserver_name -path lun_path -igroup igroup_name

  5. Rescan the host to verify removal of old paths.

    See your host documentation for specific steps to rescan your hosts.
