Recable the storage and network connections, and then give back the controller.

Step 1: Recable the controller

Recable the controller module's storage and network connections.

Steps

  1. Recable the the controller module to storage and network conntections.

  2. Verify that the cabling is correct by using Active IQ Config Advisor.

    1. Download and install Config Advisor.

    2. Enter the information for the target system, and then click Collect Data.

    3. Click the Cabling tab, and then examine the output. Make sure that all disk shelves are displayed and all disks appear in the output, correcting any cabling issues you find.

    4. Check other cabling by clicking the appropriate tab, and then examining the output from Config Advisor.

Step 2: Give back the controller

Transfer the ownership of storage resources back to the replacement controller.

  1. If your storage system has Encryption configured, you must restore Storage or Volume Encryption functionality using the following procedure to reboot the system:

    1. Boot to Menu and run Option 10

    2. Input the passphrase & backup up data, then do Normal boot see Restore onboard key management encryption keys.

    3. Perform CFO only giveback

    4. Perform Onboard Sync and verify SVM-KEK is set to true see Giveback after MB replacement fails - operation was vetoed by keymanager

    5. Giveback SFO, (no force)

  2. If your system does not have Encryption configured, complete the following procedure to reboot the system:

    1. Boot to Menu and run Option 1.

    2. Give back the controller:

    3. From the healthy controller, give back the replaced controller's storage: storage failover giveback -ofnode replacement_node_name

      The replacement controller takes back its storage and completes booting.

      Note If the giveback is vetoed, you can consider overriding the vetoes.

      Find the High-Availability Configuration content for your version of ONTAP 9

    4. After the giveback has been completed, confirm that the HA pair is healthy and that takeover is possible: storage failover show

  3. Verify that the expected volumes are present for each controller: vol show -node node-name

  4. If you disabled automatic takeover on reboot, enable it from the healthy controller: storage failover modify -node replacement-node-name -onreboot true
