Complete system restoration - AFF A150

To restore your system to full operation, you must restore the NetApp Storage Encryption configuration (if necessary), and install licenses for the new controller, and return the failed part to NetApp, as described in the RMA instructions shipped with the kit.

Step 1: Install licenses for the replacement controller in ONTAP

You must install new licenses for the replacement node if the impaired node was using ONTAP features that require a standard (node-locked) license. For features with standard licenses, each node in the cluster should have its own key for the feature.

About this task

Until you install license keys, features requiring standard licenses continue to be available to the replacement node. However, if the impaired node was the only node in the cluster with a license for the feature, no configuration changes to the feature are allowed. Also, using unlicensed features on the node might put you out of compliance with your license agreement, so you should install the replacement license key or keys on the replacement node as soon as possible.

Before you begin

The licenses keys must be in the 28-character format.

You have a 90-day grace period in which to install the license keys. After the grace period, all old licenses are invalidated. After a valid license key is installed, you have 24 hours to install all of the keys before the grace period ends.

Note If your system was initially running ONTAP 9.10.1 or later, use the procedure documented in Post Motherboard Replacement Process to update Licensing on a AFF/FAS system. If you are unsure of the initial ONTAP release for your system, see NetApp Hardware Universe for more information.
Steps

  1. If you need new license keys, obtain replacement license keys on the NetApp Support Site in the My Support section under Software licenses.

    Note The new license keys that you require are automatically generated and sent to the email address on file. If you fail to receive the email with the license keys within 30 days, you should contact technical support.

  2. Install each license key: system license add -license-code license-key, license-key...

  3. Remove the old licenses, if desired:

    1. Check for unused licenses: license clean-up -unused -simulate

    2. If the list looks correct, remove the unused licenses: license clean-up -unused

Step 2: Verify LIFs and register the serial number

Before returning the replacement node to service, you should verify that the LIFs are on their home ports, and register the serial number of the replacement node if AutoSupport is enabled, and reset automatic giveback.

Steps

  1. Verify that the logical interfaces are reporting to their home server and ports: network interface show -is-home false

    If any LIFs are listed as false, revert them to their home ports: network interface revert -vserver * -lif *

  2. Register the system serial number with NetApp Support.

    • If AutoSupport is enabled, send an AutoSupport message to register the serial number.

    • If AutoSupport is not enabled, call NetApp Support to register the serial number.

  3. If an AutoSupport maintenance window was triggered, end it by using the system node autosupport invoke -node * -type all -message MAINT=END command.

  4. If automatic giveback was disabled, reenable it: storage failover modify -node local -auto-giveback true

Step 3: Switch back aggregates in a two-node MetroCluster configuration

After you have completed the FRU replacement in a two-node MetroCluster configuration, you can perform the MetroCluster switchback operation. This returns the configuration to its normal operating state, with the sync-source storage virtual machines (SVMs) on the formerly impaired site now active and serving data from the local disk pools.

This task only applies to two-node MetroCluster configurations.

Steps

  1. Verify that all nodes are in the enabled state: metrocluster node show

    cluster_B::>  metrocluster node show

DR                           Configuration  DR
Group Cluster Node           State          Mirroring Mode
----- ------- -------------- -------------- --------- --------------------
1     cluster_A
              controller_A_1 configured     enabled   heal roots completed
      cluster_B
              controller_B_1 configured     enabled   waiting for switchback recovery
2 entries were displayed.

  2. Verify that resynchronization is complete on all SVMs: metrocluster vserver show

  3. Verify that any automatic LIF migrations being performed by the healing operations were completed successfully: metrocluster check lif show

  4. Perform the switchback by using the metrocluster switchback command from any node in the surviving cluster.

  5. Verify that the switchback operation has completed: metrocluster show

    The switchback operation is still running when a cluster is in the waiting-for-switchback state:

    cluster_B::> metrocluster show
Cluster              Configuration State    Mode
--------------------	------------------- 	---------
 Local: cluster_B configured       	switchover
Remote: cluster_A configured       	waiting-for-switchback

    The switchback operation is complete when the clusters are in the normal state.:

    cluster_B::> metrocluster show
Cluster              Configuration State    Mode
--------------------	------------------- 	---------
 Local: cluster_B configured      		normal
Remote: cluster_A configured      		normal

    If a switchback is taking a long time to finish, you can check on the status of in-progress baselines by using the metrocluster config-replication resync-status show command.

  6. Reestablish any SnapMirror or SnapVault configurations.

Step 4: Return the failed part to NetApp

Return the failed part to NetApp, as described in the RMA instructions shipped with the kit. See the Part Return and Replacements page for further information.
