Complete system restoration - AFF A900

Contributors dougthomp thrisun

To complete the replacement procedure and restore your system to full operation, you must recable the storage, restore the NetApp Storage Encryption configuration (if necessary), and install licenses for the new controller. You must complete a series of tasks before restoring your system to full operation.

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.

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.

If the node is in a MetroCluster configuration and all nodes at a site have been replaced, license keys must be installed on the replacement node or nodes prior to switchback.

  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 registering 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.

  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: 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 & Replacements page for further information.
