◦ For nondisruptive replacement, the HA pair must be connected to a network to restore the var file
system.
◦ For disruptive replacement, you do not need a network connection to restore the var file system, but
the process requires two reboots.
• You must replace the failed component with a replacement FRU component you received from your
provider.
• It is important that you apply the commands in these steps on the correct controller:
◦ The impaired controller is the controller on which you are performing maintenance.
◦ The healthy controller is the HA partner of the impaired controller.
Check onboard encryption keys - AFF A200
Prior to shutting down the impaired controller and checking the status of the onboard
encryption keys, you must check the status of the impaired controller, disable automatic
giveback, and check the version of ONTAP that is running.
If you have a cluster with more than two nodes, it must be in quorum. If the cluster is not in quorum or a healthy
controller shows false for eligibility and health, you must correct the issue before shutting down the impaired
controller; see the NetApp Encryption overview with the
Steps
1. Check the status of the impaired controller:
◦ If the impaired controller is at the login prompt, log in as admin.
◦ If the impaired controller is at the LOADER prompt and is part of HA configuration, log in as
the healthy controller.
◦ If the impaired controller is in a standalone configuration and at LOADER prompt, contact
mysupport.netapp.com.
2. If AutoSupport is enabled, suppress automatic case creation by invoking an AutoSupport message:
system node autosupport invoke -node * -type all -message
MAINT=number_of_hours_downh
The following AutoSupport message suppresses automatic case creation for two hours:
system node autosupport invoke -node * -type all -message MAINT=2h
3. Check the version of ONTAP the system is running on the impaired controller if up, or on the partner
controller if the impaired controller is down, using the
◦ If <lno-DARE> or <1Ono-DARE> is displayed in the command output, the system does not support
NVE, proceed to shut down the controller.
◦ If <lno-DARE> is not displayed in the command output, and the system is running ONTAP 9.5, go to
Option 1: Checking NVE or NSE on systems running ONTAP 9.5 and
◦ If <lno-DARE> is not displayed in the command output, and the system is running ONTAP 9.6 or later,
go to Option 2: Checking NVE or NSE on systems running ONTAP 9.6 and
4. If the impaired controller is part of an HA configuration, disable automatic giveback from the healthy
