Replacing the boot media
The boot media stores a primary and secondary set of system (
boot image
) files that the system
uses when it boots. Depending on your network configuration, you can perform either a
nondisruptive or disruptive replacement.
Before you begin
You must have a USB flash drive, formatted to FAT32, with the appropriate amount of storage to
hold the image_xxx.tgz.
About this task
• The nondisruptive and disruptive methods for replacing a boot media both require you to
restore the var file system:
◦ 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.

Pre-shutdown checks for onboard encryption keys
Prior to shutting down the impaired node and checking the status of the onboard encryption keys,
you must check the status of the impaired node, disable automatic giveback, and check what
version of ONTAP the system is running.
Before you begin
• 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 node shows false for eligibility and health, you must correct the issue
before shutting down the impaired node.
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.
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:
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, go
to
Shutting down the impaired controller
on page 11.
• If <lno-DARE> is not displayed in the command output, and the system is running ONTAP
9.5, go to
Checking NVE or NSE on systems running ONTAP 9.5 and earlier
on page 5
• If <lno-DARE> is not displayed in the command output,, and the system is running
ONTAP 9.6 or later, go to
Checking NVE or NSE on systems running ONTAP 9.6 and later
on page 8
4. If the impaired node is part of an HA configuration, disable automatic giveback from the
healthy node:
storage failover modify -node local -auto-giveback false
storage failover modify -node local -auto-giveback-after-panic false
Checking NVE or NSE on systems running ONTAP 9.5 and earlier
Before shutting down the impaired node, 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.
Steps
1. Connect the console cable to the impaired node.
2. Check 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.
3. Check 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 NVE and NSE are not configured, it's safe to shut down the impaired node.
Verifying NVE configuration
Steps
1. Display the key IDs of the authentication keys that are stored on the key management servers:
security key-manager query
• If the Restored column displays yes and all key managers display available, it's
safe to shut down the impaired node.
