HPE Nimble Storage HF Series Hardware Manual page 106

A replacement chassis comes without drives, controllers, or power supplies. Those components come from your existing array.
CAUTION:
Before you attempt to replace the chassis:
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?
Schedule for adequate downtime during hours of minimal array use.
Disconnect the array from your VMware host.
Unmount the array from your host.
Procedure
1. 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 --array array_name.
2. Label the cables for all connections so that you can easily reconnect them to the correct ports during installation.
3. Unplug the power cords, network cables, and SAS cables from the array, and remove the front bezel.
4. Remove the existing array from the rack.
5. Install the new chassis into the rack.
6. Move the drive carriers from the existing array to the new chassis.
Do not remove a drive from its drive carrier.
a) Slide the black release tab toward the carrier LED. The handle springs open.
For Dual Flash drive carriers, you must remove the small retention clip that is directly next to the release tab by firmly
grasping it and pulling straight out.
b) Pull the drive carrier handle to remove the drive in slot 1 from the existing array. Use firm, steady pressure.
For Dual Flash drive carriers, press the release tab and pull the drive carrier from the chassis bay.
c) 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.
d) Close the drive carrier handle.
Push the handle until it fully engages with the release tab.
e) 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.
