Overview of boot media replacement - AFF A700 and FAS9000

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.

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 does not require connection to a network to restore the var file system. The HA pair in a single chassis has an internal e0S connection, which is used to transfer var config between them.

    • 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.

If you need to replace the secondary boot media while the primary boot media is installed and healthy, contact NetApp Support and mention the How to replace the secondary boot device of an AFF A700s KB article.
