ONTAP 9 System Administration Reference
Steps
1. Check the status of the impaired node:
◦If the impaired node is at the login prompt, log in as admin.
◦If the impaired node is at the LOADER prompt and is part of HA configuration, log in as admin on the
healthy node.
◦If the impaired node is in a standalone configuration and at LOADER prompt, contact NetApp Support.

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 node if up, or on the partner node if the
impaired node is down, using the version -v command:
◦If <lno-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 9.6 or later,
go to go to the next section.
Check NVE or NSE on systems running ONTAP 9.6 and later
Before shutting down the impaired node, you need to verify whether the system has
either NetApp Volume Encryption (NVE) or NetApp Storage Encryption (NSE) enabled. If
so, you need to verify the configuration.
1. Verify whether NVE is configured for any volumes in the cluster: volume show -is-encrypted true
If any volumes are listed in the output, NVE is configured and you need to verify the NVE configuration. If
no volumes are listed, check whether NSE is configured.
2. Verify whether NSE is configured: storage encryption disk show
◦If the command output list the drive details with Mode & Key ID information, NSE is configured and you
need to verify the NSE configuration.
◦If no disks are shown, NSE is not configured.
◦If NVE and NSE are not configured, it’s safe to shut down the impaired node.
Verify NVE configuration
1. Display the key IDs of the authentication keys that are stored on the key management servers: security
key-manager query
◦If the Key Manager type displays external and the Restored column displays yes, it’s safe to shut
down the impaired node.
◦If the Key Manager type displays onboard and the Restored column displays yes, you need to
