Replacing the chassis

To replace the chassis, you must move the power supplies, hard drives, and controller module or modules from the impaired chassis to the new chassis, and swap out the impaired chassis from the equipment rack or system cabinet with the new chassis of the same model as the impaired chassis.

Before you begin

All other components in the system must be functioning properly; if not, you must contact technical support.

About this task

  • You can use this procedure with all versions of ONTAP supported by your system.
  • This procedure is written with the assumption that you are moving all disk drives and controller module or modules to the new chassis, and that the chassis is a new component from Lenovo.
  1. Workflow diagram
    This diagram shows the workflow of the chassis replacement procedure for a system.
  2. Shutting down the controller
    You must shut down the controller or controllers in the chassis prior to moving them to the new chassis.
  3. Swapping out a power supply
    Swapping out a power supply when replacing a chassis involves turning off, disconnecting, and removing the power supply from the old chassis and installing and connecting it on the replacement chassis.
  4. Removing the controller module
    To replace the chassis, you must remove the controller module or modules from the old chassis.
  5. Moving drives to the new chassis
    You need to move the drives from each bay opening in the old chassis to the same bay opening in the new chassis.
  6. Replacing a chassis from within the equipment rack or system cabinet
    You must remove the existing chassis from the equipment rack or system cabinet before you can install the replacement chassis.
  7. Installing the controller
    After you install the controller module and any other components into the new chassis, boot it to a state where you can run the interconnect diagnostic test.
  8. Verifying and setting the HA state of the chassis
    You must verify the HA state of the chassis, and, if necessary, update the state to match your system configuration.
  9. Running system-level diagnostics
    After installing a new chassis, you should run interconnect diagnostics.
  10. 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.
