◦
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 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 - FAS2600
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 what version of ONTAP the system is running.
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
