Before you begin
• Check the
NetApp Hardware Universe to make sure that the new I/O module is compatible with your
system and version of ONTAP you’re running.
• If multiple slots are available, check the slot priorities in NetApp Hardware Universe and use the best one
available for your I/O module.
• To non-disruptively add an I/O module, you must take over the target controller, remove the slot blanking
cover in the target slot or remove an existing I/O module, add the new or replacement I/O module, and then
giveback the target controller.
• Make sure that all other components are functioning properly.
Option 1: Add the I/O module to a system with open slots
You can add an I/O module into an empty module slot in your system as either a NIC or a
storage module for the NS224 storage shelves.
1. Shutdown controller A:
a.
Disable automatic giveback:
storage failover modify -node local -auto-giveback
false
b.
Take over the target node:
storage failover takeover -ofnode target_node_name
The console connection shows that the node drops to the LOADER prompt when the take over is
complete.
2. If you are not already grounded, properly ground yourself.
3. Remove the target slot blanking cover:
a. Depress the lettered and numbered cam button.
b. Rotate the cam latch down until it is the open position.
c. Remove the blanking cover.
4. Install the I/O module:
a. Align the I/O module with the edges of the slot.
b. Slide the I/O module into the slot until the lettered and numbered I/O cam latch begins to engage with
the I/O cam pin.
c. Push the I/O cam latch all the way up to lock the module in place.
5. If the replacement I/O module is a NIC, cable the module to the data switches.
Make sure that any unused I/O slots have blanks installed to prevent possible thermal
issues.
6. Reboot the node from the LOADER prompt: bye
7.
Give back the node from the partner node.
storage failover giveback -ofnode
target_node_name
8.
Enable automatic giveback if it was disabled:
storage failover modify -node local -auto
-giveback true
9.
If you are using slots 3 and/or 7 for networking, use the storage port modify -node <node name>
-port <port name> -mode network command to convert the slot for networking use.
