Reassign drives from node2 to node4

Contributors netapp-pcarriga

After converting AFF A250 node2 to an NS224 drive shelf and connecting to AFF A400 node4, you must reassign the drives that previously belonged to node2 to node4.

Before you begin

Verify that both node3 and node4 are on standby at the LOADER prompt.

About this task

You perform the following steps on node4.

Steps

  1. At the LOADER prompt, boot node4 into Maintenance Mode:

    boot_ontap maint

  2. Show the state of the 100GbE interfaces:

    storage port show

  3. Set the 100GbE interfaces to storage ports:

    storage port modify -p e0c -m storage

    storage port modify -p e0d -m storage

  4. Verify the mode changes to the 100GbE interfaces:

    storage port show

    Output like the following example should display:

    *> storage port modify -p e0c -m storage
Nov 10 16:27:23 [localhost:nvmeof.port.modify:notice]: Changing NVMe-oF port e0c to storage mode.

Nov 10 16:27:29 [localhost:nvmeof.subsystem.add:notice]: NVMe-oF subsystem added at address fe80::2a0:98ff:fefa:8885.

*> storage port modify -p e0d -m storage
Nov 10 16:27:34 [localhost:nvmeof.port.modify:notice]: Changing NVMe-oF port e0d to storage mode.

Nov 10 16:27:38 [localhost:nvmeof.subsystem.add:notice]: NVMe-oF subsystem added at address fe80::2a0:98ff:fefa:8886.

*> storage port show
Port Type Mode    Speed(Gb/s) State    Status  VLAN ID
---- ---- ------- ----------- -------- ------- -------
e0c  ENET storage 100 Gb/s    enabled  online  30
e0d  ENET storage 100 Gb/s    enabled  offline 30

  5. Display all attached drives:

    disk show -v

  6. Record the local system ID value; this is the system ID of node4. Also record the system IDs of node1 and node2 from the "OWNER" column.

  7. Reassign all drives from node2 to node4:

    disk reassign -s node2_system_ID -d node4_system_ID -p node1_system_ID

  8. Verify that all reassigned drives are viewable to the new system ID:

    disk show -s node4_System_ID

    Note If drives are not viewable, STOP and contact technical support for assistance.

  9. Verify that the root aggregate of node2 is reported in the output and the aggregate is online:

    aggr status

  10. Exit maintenance mode:

    halt

Migrate data aggregates, epsilon, and LIFs on node1 to node4
