Steps
1. If your system has two controller modules, disable the HA pair.
If your system is running
clustered ONTAP with…
Then…
Two controllers in the cluster
cluster ha modify -configured false storage failover
modify -node node0 -enabled false
More than two controllers in the
cluster
storage failover modify -node node0 -enabled false
2.
Halt the controller, pressing
y when you are prompted to confirm the halt: system node halt -node
node_name
The confirmation message looks like the following:
Warning: This operation will cause controller "node-name" to be marked
as unhealthy. Unhealthy nodes do not participate in quorum voting. If
the controller goes out of service and one more controller goes out of
service there will be a data serving failure for the entire cluster.
This will cause a client disruption. Use "cluster show" to verify
cluster state. If possible bring other nodes online to improve the
resiliency of this cluster.
Do you want to continue? {y|n}:
You must perform a clean system shutdown before replacing the chassis to avoid losing
unwritten data in the nonvolatile memory (NVMEM/NVRAM). Depending on your system, if
the NVMEM/NVRAM LED is flashing, there is content in the NVMEM/NVRAM that has not
been saved to disk. You need to reboot the controller and start from the beginning of this
procedure. If repeated attempts to cleanly shut down the controller fail, be aware that you
might lose any data that was not saved to disk.
3. Where applicable, halt the second controller to avoid a possible quorum error message in an HA pair
configuration:
system node halt -node second_node_name -ignore-quorum-warnings true
-skip-lif-migration-before-shutdown true
Answer y when prompted.
Replace hardware - AFF A700s
Move the power supplies, hard drives, and controller module or modules from the
impaired chassis to the new chassis, and swap out the impaired chassis from the
equipment rack or system cabinet with the new chassis of the same model as the
impaired chassis.
