Replacing the boot media

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

  • 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.
  1. Pre-shutdown checks for onboard encryption keys
    Prior to shutting down the impaired node and checking the status of the onboard encryption keys, you must check the status of the impaired node, disable automatic giveback, and check what version of ONTAP the system is running.
  2. Shutting down the impaired controller
    You can shut down or take over the impaired controller using different procedures, depending on the storage system hardware configuration.
  3. Removing the controller module
    You must remove the controller module from the chassis when you replace a component inside the controller module.
  4. Replacing the boot media
    You locate the failed boot media in the controller module by removing the air duct on the controller module before you can replace the boot media.
  5. Transferring the boot image to the boot media
    The replacement boot media that you installed is without a boot image so you need to transfer a boot image using a USB flash drive.
  6. Booting the recovery image
    You must boot the ONTAP image from the USB drive, restore the file system, and verify the environmental variables.
  7. Completing the replacement process
    After you replace the part, you can return the failed part to Lenovo, as described in the RMA instructions shipped with the kit.Contact technical support at Lenovo Data Center Support if you need the RMA number or additional help with the replacement procedure.
