• Can your storage cluster remain online when you remove the nodes that are part of the failed chassis?
• Can your virtual machines (VMs) and ESXi cluster handle the workload when you remove the compute
nodes that are part of the failed chassis?
Replacement options
Choose from one of the following options below:
Replace the chassis when additional unused space is available in the rack
Replace the chassis when additional unused space is not available in the rack
Replace the chassis when additional unused space is available in the rack
If your rack has additional space, you can install the new chassis and move nodes one at a time to the new
chassis. If any of the installed chassis have unused node slots, you can move nodes from the failed chassis to
the unused slots one at a time, and then remove the failed chassis. Before you being the procedure, ensure
that the cable lengths are sufficient and switch ports are available.
The steps for moving compute nodes are different from the steps for moving storage nodes.
You should ensure that the nodes are correctly shut down before you move them. After you
move all the nodes from the failed chassis, you should remove the chassis from the rack and
return it to NetApp.
Install the new chassis
You can install the new chassis into the rack space available, and move the nodes into it.
What you’ll need
• You have an electrostatic discharge (ESD) wristband, or you have taken other antistatic protection.
• You have the replacement chassis.
• You have a lift or two or more persons to perform the steps.
• You have a #1 Phillips screwdriver.
Steps
1. Put on antistatic protection.
2. Unpack the replacement chassis.
Keep the packaging for when you return the failed chassis to NetApp.
3. Insert the rails that were shipped to you along with the chassis.
4. Slide the replacement chassis into the rack.
Always use sufficient manpower or a lift while installing the chassis.
5. Secure the chassis to the rack with the front mounting thumb screws, and tighten the screws with the
screwdriver.
Move a compute node
Before you move a compute node to the new chassis or to an existing chassis that has additional unused slots,
you should migrate the virtual machines (VMs), shut the node down correctly, and label the cables inserted into
the node.
