Creating your file...
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.
You must have a USB flash drive, formatted to FAT32, with the appropriate amount of storage to hold the image_xxx.tgz
file.
You also must copy the image_xxx.tgz
file to the USB flash drive for later use in this procedure.
-
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.
