A replacement chassis comes without drives, controllers, and power supplies. Those components come from your existing array.

CAUTION:

Before you attempt to replace the chassis:

Schedule for adequate downtime during hours of minimal array use.
Disconnect the array from your VMware host.
Unmount the array from your Linux host.
Plan how you want to install the new chassis into the rack. Does the existing array have to be removed first? Do you have a jack, or other lifting device, or a second person to help you lift the array into place?

Procedure

Shut down the existing array using one of the following methods:
- In the GUI, go to Administration > Shutdown and click Shut Down Array.
- In the CLI, type
  halt --arrayarray name
  .
- On the array, press and hold the power button for 4 seconds.
Label the cables for all eth/port connections so that you can easily reconnect them to the correct ports during installation.
Unplug the power cords, network cables, and SAS cables from the array, and remove the front bezel.
Remove the existing array from the rack.
Remove the rack rails from the existing array and install them onto the new chassis.
Install the new chassis into the rack.
Move the drive carriers from the existing array to the new chassis. HDDs and SSDs follow the same procedure. Do not remove a drive from its drive carrier.
1. Slide the red tab down to release the drive carrier handle. The handle springs open.
2. Pull the drive carrier handle to remove the drive in slot 1 from the existing array. Use firm, steady pressure.
3. Slide the drive into the drive bay of slot 1 on the new chassis. Do not force the drive. If it does not slide in smoothly, remove it and start again.
4. Close the drive carrier handle.
5. Repeat this action with the other drive carriers.
  Important: Always install each drive into the same slot number on the new chassis as on the existing array.
Move the controllers from the existing array to the new chassis.
1. Unscrew the keeper to release the handle on one of the controllers.
2. Grasp the controller by the handle, pull the controller firmly to remove it from the chassis bay.
3. Slide the controller into a bay on the new chassis.
  Do not force the controller. If it does not slide in easily, remove it and try again.
4. Return the handle to its original closed position and tighten the keeper screw.
5. Repeat this action with the other controller.
  A controller can be installed in either bay of the new chassis.
Move the power supplies from the existing array to the new chassis.
1. Press the release tab to the left on one of the power supplies.
2. Grasp the power supply by the handle, pull the power supply firmly to remove it from the chassis bay.
3. Slide the power supply into a bay on the new chassis.
  Note: Do not force the power supply. If it does not slide in easily, remove it and try again.
4. Return the power supply handle to its original closed position and press the release tab to the right.
5. Repeat this action with the power supply.
  A power supply can be installed in either bay of the new chassis.
With all components from the existing array installed into the new chassis, the new chassis becomes the new array.
Plug in the power cords, network cables, and SAS cables into the new array, and replace the front bezel.
Power the array. Press the power button on the front of the chassis.
Contact Nimble Storage Support. They will verify that the array is operating properly.
Return the old chassis as directed on the RMA work order.
