provider.
• It is important that you apply the commands in these steps on the correct node:
◦
The
impaired
node is the node on which you are performing maintenance.
◦
The
healthy node
is the HA partner of the impaired node.
Check onboard encryption keys - AFF A220 and FAS2700
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 CLI
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
admin
on
the healthy controller.
◦
If the impaired controller is in a standalone configuration and at LOADER prompt, contact
.
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:
cluster1:*>
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
version -v
command:
◦
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 earlier]
◦
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 later]
4. If the impaired controller is part of an HA configuration, disable automatic giveback from the healthy
controller:
storage failover modify -node local -auto-giveback false
or
storage
failover modify -node local -auto-giveback-after-panic false
Option 1: Check NVE or NSE on systems running ONTAP 9.5 and earlier
Before shutting down the impaired controller, you need to check whether the system has
either NetApp Volume Encryption (NVE) or NetApp Storage Encryption (NSE) enabled. If
so, you need to verify the configuration.
