Overview of boot media replacement - AFF A200

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. The AFF A200 system supports only manual boot media recovery procedures. Automated boot media recovery is not supported.

Note

NetApp strongly recommends that you enable console logging on the devices you are working with and take the following actions when performing this procedure:

  • Leave AutoSupport enabled during your maintenance. This allows NetApp support to receive diagnostic information if issues occur.

  • Enable session logging for any CLI sessions. This creates a complete record of all commands and system output during the maintenance activity. For guidance on how to enable session logging, see How to configure PuTTY for optimal connectivity to ONTAP systems.
What you'll need

You must have a USB flash drive, formatted to FAT32, with the appropriate amount of storage to hold the image_xxx.tgz file.

Before you begin

  • 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 controller:

    • The impaired controller is the controller on which you are performing maintenance.

    • The healthy controller is the HA partner of the impaired controller.
