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.

Steps
1. Check the status of the impaired node:
• If the impaired node is at the login prompt, log in as admin.
