Replacing the chassis

• You can use this procedure with all versions of ONTAP supported by your system.
• This procedure is disruptive. For a two-node cluster, you will have a complete service outage and a partial
outage in a multi-node cluster.
Shutting down the controllers when replacing a chassis
You must shut down the controllers before replacing the chassis.
Shutting down the nodes
You must shut down the nodes in the chassis prior to moving them to the new chassis.

• If you have a cluster with more than two nodes, it must be in quorum. If the cluster is not in quorum or a
healthy node shows false for eligibility and health, you must correct the issue before shutting down the
impaired node.

Two nodes in the cluster
More than two nodes in the cluster
Step 2.
Halt the node, pressing y when you are prompted to confirm the halt:
system node halt -node node_name
The confirmation message looks like the following:
Warning: Rebooting or halting node
"node_name" in an HA-enabled cluster may result in client disruption or data access
failure. To ensure continuity of service, use the "storage
failover takeover" command. Are you sure you want to halt node
"node_name"? {y|n}:
Attention: You must perform a clean system shutdown before replacing chassis to avoid losing
unwritten data in the nonvolatile memory (NVRAM). If the NVRAM LED is flashing, there is content
in the NVRAM that has not been saved to disk. You need to reboot the controller module and start
from the beginning of this procedure. If repeated attempts to cleanly shut down the controller
module fail, be aware that you might lose any data that was not saved to disk.
Step 3.
Where applicable, halt the second node to avoid a possible quorum error message in an HA pair
configuration::
system node halt -node second_node_name -ignore-quorum-warnings true
