Get started with replacing the boot media in your AFF A800 storage system by reviewing the replacement requirements, checking encryption status, shutting down the controller, replacing the boot media, booting the recovery image, restoring encryption, and verifying the system functionality.
If your storage system is running ONTAP 9.17.1 or later, use the automated boot recovery procedure. If your system is running an earlier version of ONTAP, you must use the manual boot recovery procedure.
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.
