The automated recovery of the boot image involves the system automatically identifying and selecting the appropriate boot menu option. It uses the boot image on the partner node to reinstall ONTAP on the replacement boot media in your AFF A400 storage system.
The automated boot media recovery process is supported only in ONTAP 9.17.1 and later. If your storage system is running an earlier version of ONTAP, use the manual boot recovery procedure.
To get started, review the replacement requirements, shut down the controller, replace the boot media, allow the system to restore the image, and verify system functionality.
Review the requirements for replacing the boot media.
Determine whether the system has security key manager enabled or encrypted disks.
Shut down the controller when when you need to replace the boot media.
Remove the failed boot media from the System Management module and install the replacement boot media, and then transfer an ONTAP image using a USB flash drive.
Boot the ONTAP image from the USB drive, restore the file system, and verify the environmental variables.
Restore the onboard key manager configuration or the external key manager from the ONATP boot menu.
Return the failed part to NetApp, as described in the RMA instructions shipped with the kit.
