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.
ONTAP 9 System Administration Reference
Step 1.
Disable the HA pair.
If your system is running clustered ONTAP
with...
Two nodes in the cluster
More than two nodes in the cluster
Step 2.
Halt the node, pressing
The confirmation message looks like the following:
name
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::
Removing the controller modules
To replace the chassis, you must remove the controller modules from the old chassis.

Step 1.
If you are not already grounded, properly ground yourself.
Step 2.
Unplug the controller module power supplies from the source.
Step 3.
Release the power cable retainers, and then unplug the cables from the power supplies.
Step 4.
Remove the storage and networking cables.
Step 5.
Insert your forefinger into the latching mechanism on either side of the controller module, press the
lever with your thumb, and gently pull the controller a few inches out of the chassis.
Note: If you have difficulty removing the controller module, place your index fingers through the
finger holes from the inside (by crossing your arms)
when you are prompted to confirm the halt:
y
system node halt -node second_node_name -ignore-quorum-warnings true
Then...
cluster ha modify -configured false storage failover
modify -node node0 -enabled false
storage failover modify -node node0 -enabled false
system node halt -node node_
.
