The following AutoSupport message suppresses automatic case creation for two hours: cluster1:*>
system node autosupport invoke -node * -type all -message MAINT=2h
Steps
1. If your system has two controller modules, disable the HA pair.
If your system is running
clustered ONTAP with…
Then…
Two nodes in the cluster
cluster ha modify -configured false storage failover
modify -node node0 -enabled false
More than two nodes in the
cluster
storage failover modify -node node0 -enabled false
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: This operation will cause node "node-name" to be marked as
unhealthy. Unhealthy nodes do not participate in quorum voting. If the
node goes out of service and one more node 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 node and start from the beginning of this
procedure. If repeated attempts to cleanly shut down the node fail, be aware that you might
lose any data that was not saved to disk.
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
-skip-lif-migration-before-shutdown true
Answer y when prompted.
Move and replace hardware - AFF A900
To replace the chassis, you must remove the components from the old chassis and install
them in the replacement chassis.
