Move non-root aggregates and NAS data LIFs owned by node1 from node2 to node3

After you verify network configuration on node3 and before you relocate aggregates from node2 to node3, you must verify that the NAS data LIFs belonging to node1 that are currently on node2 are relocated from node2 to node3. You must also verify that the SAN LIFs exist on node3.

About this task

Remote LIFs handle traffic to SAN LUNs during the upgrade procedure. Moving SAN LIFs is not necessary for cluster or service health during the upgrade. SAN LIFs are not moved unless they need to be mapped to new ports. You will verify that the LIFs are healthy and located on appropriate ports after you bring node3 online.

Note If you are changing the port speed of the T6-based Ethernet network interface cards or motherboard ports, you might observe malformed packets being received after the speed conversion. See NetApp Bugs Online Bug ID 1570339 and the knowledge base article CRC errors on T6 ports after converting from 40GbE to 100GbE for guidance.
Steps

  1. Resume the relocation operation:

    system controller replace resume

    The system performs the following tasks:

    • Cluster quorum check

    • System ID check

    • Image version check

    • Target platform check

    • Network reachability check

    The operation pauses at this stage in the network reachability check.

  2. Resume the relocation operation:

    system controller replace resume

    The system performs the following checks:

    • Cluster health check

    • Cluster LIF status check

    After performing these checks, the system relocates the non-root aggregates and NAS data LIFs owned by node1 to the new controller, node3.
    The controller replacement operation pauses after the resource relocation is complete.

  3. Check the status of the aggregate relocation and NAS data LIF move operations:

    system controller replace show-details

    If the controller replacement procedure is paused, check and correct the error, if any, and then issue resume to continue the operation.

  4. If necessary, restore and revert any displaced LIFs. List any displaced LIFs:

    cluster controller-replacement network displaced-interface show

    If any LIFs are displaced, restore the home node back to node3:

    cluster controller-replacement network displaced-interface restore-home-node

  5. Resume the operation to prompt the system to perform the required post-checks:

    system controller replace resume

    The system performs the following post-checks:

    • Cluster quorum check

    • Cluster health check

    • Aggregates reconstruction check

    • Aggregate status check

    • Disk status check

    • Cluster LIF status check

    • Volume check
