After installing the new boot media device in your system, you can boot the recovery image from a USB drive and restore the configuration from the partner node.

If your storage system is running ONTAP 9.17.1 or later, use the automated boot recovery procedure. If your system is running an earlier version of ONTAP, you must use the manual boot recovery procedure.

Before you begin

  • Ensure your console is connected to the impaired controller.

  • Verify you have a USB flash drive with the recovery image.

  • Determine if your system uses encryption. You will need to select the appropriate option in step 3 based on whether encryption is enabled.

Steps

  1. From the LOADER prompt on the impaired controller, boot the recovery image from the USB flash drive:

    boot_recovery

    The recovery image is downloaded from the USB flash drive.

  2. When prompted, enter the name of the image or press Enter to accept the default image displayed in brackets.

  3. Restore the var file system using the procedure for your ONTAP version:

    ONTAP 9.16.0 or earlier

    Complete the following steps on the impaired controller and partner controller:

    1. On the impaired controller: Press Y when you see Do you want to restore the backup configuration now?

    2. On the impaired controller: If prompted, press Y to overwrite /etc/ssh/ssh_host_ecdsa_key.

    3. On the partner controller: Set the impaired controller to advanced privilege level:

      set -privilege advanced

    4. On the partner controller: Run the restore backup command:

      system node restore-backup -node local -target-address impaired_node_IP_address

      Note If you see any message other than a successful restore, contact NetApp Support.

    5. On the partner controller: Return to admin level:

      set -privilege admin

    6. On the impaired controller: Press Y when you see Was the restore backup procedure successful?

    7. On the impaired controller: Press Y when you see …​would you like to use this restored copy now?

    8. On the impaired controller: Press Y when prompted to reboot, then press Ctrl-C when you see the Boot Menu.

    9. On the impaired controller: Do one of the following:

      • If the system does not use encryption, select Option 1 Normal Boot from the Boot Menu.

      • If the system uses encryption, go to Restore encryption.

    ONTAP 9.16.1 or later

    Complete the following steps on the impaired controller:

    1. Press Y when prompted to restore the backup configuration.

      After the restore procedure is successful, this message displays: syncflash_partner: Restore from partner complete

    2. Press Y when prompted to confirm that the restore backup was successful.

    3. Press Y when prompted to use the restored configuration.

    4. Press Y when prompted to reboot the node.

    5. Press Y when prompted to reboot again, then press Ctrl-C when you see the Boot Menu.

    6. Do one of the following:

      • If the system does not use encryption, select Option 1 Normal Boot from the Boot Menu.

      • If the system uses encryption, go to Restore encryption.

  4. Connect the console cable to the partner controller.

  5. Return the controller to normal operation by giving back its storage:

    storage failover giveback -fromnode local

  6. If you disabled automatic giveback, reenable it:

    storage failover modify -node local -auto-giveback true

  7. If AutoSupport is enabled, restore automatic case creation:

    system node autosupport invoke -node * -type all -message MAINT=END
