Steps

1. Check the status of the target node (the node you want to perform maintenance on) by entering the following command atthe system console of either node:

If your system is configured in... Then issue this command...

7-Mode cf status

Cluster-Mode storage failover show

2. Take one of the following actions, depending on the result of the cf status or storage failover show command:

If... Then...

Neither node is in takeover mode Go to the next step in this procedure.

The partner node took over the targetnode

The target node is in a state where you can begin removing it from the system chassis.

The target node took over the partnernode

a. Correct the problem that caused the takeover.

b. Run the cf giveback command (if in a 7-Mode system) or storage failovergiveback (if in a Cluster-Mode system) from the target node console.

c. Go back to the beginning of this procedure.

3. Take over the target node by entering the following command from the partner node’s console:

If your system is configured in... Then issue this command...

7-Mode cf takeover

Cluster-Mode storage failover takeover -bynode node

Shutting down the node in a stand-alone systemFor a node that is not configured with a high-availability (HA) partner, you must perform a clean shutdown (ensuring that alldata has been written to disk) and disconnect the power supplies.

Steps

1. Enter one of the following commands from the system console:

If your system is configured as a... Then issue this command...

7-Mode system halt

Cluster-Mode system halt local

Attention: You must perform a clean system shutdown before replacing system components to avoid losing unwrittendata in the NVRAM. The NVRAM adapter has a red LED that blinks if there is unwritten data in the NVRAM. If thisLED is flashing red after you enter the halt command, reboot your system and try halting it again.

2. If you are not already grounded, properly ground yourself.

3. Turn off the power supplies and unplug both power cords from the power source:

If your system uses... Then...

AC power supplies Unplug the power cords from the power source, and then remove the power cords.

DC power supplies Remove the power at the DC source, and remove the DC wires, if necessary.

2 Installing or replacing the RLM in a 31xx system

Opening the systemTo access components inside the controller module, you must open the system.

Steps

1. If you are not already grounded, properly ground yourself.

2. Unplug the system cables from the controller module, as needed, and keep track of where the cables were connected.

Leave the cables in the cable clips of the cable management tray so that when you reinstall the cable management tray, thecables are already aligned.

3. Grasp the cable management tray by the side, gently push one side of the tray so that the arm slides across and off theretaining pin, and then lift off the back of the controller module and set it aside.

4. Loosen the thumbscrew on the cam handle.

5. Pull the cam handle downward and slide the controller module out of the system until it catches.

6. Push in the blue release latch on the left side of the controller module and slide the controller module out of the system.

Release the latch after you can slide the controller module. Make sure that you support the bottom of the controller modulewith your free hand.

Removing the RLMTo remove the RLM from the system, you must perform a specific sequence of steps.

Steps

1. Locate the RLM in the center of the riser housing, using the RLM label on the controller module DIMM cover as areference.

2. Pinch the retaining tabs on the RLM, and then lift the RLM straight out of the socket and the housing.

3. Set the RLM aside.

Installing the RLMYou must complete a specific set of steps to install the RLM in the system.

Step

1. Align the edges of the RLM with the guide slots on the edges of the riser housing, lower the RLM into place, and then pressthe RLM into the socket by using your thumbs in the top center of the RLM.

Make sure that you press down at the places indicated by the sticker on the RLM housing.

Reinstalling the controller module and booting the systemAfter you replace a component within the controller module, you must reinstall the controller module in the system chassis.

About this task

Attention: For HA pairs, the sequence in which you reinstall the controller module is especially important because it attemptsto reboot as soon as you completely seat it in the chassis.

Steps

1. Close the DIMM cover and side panel, if necessary.

2. Align the end of the controller module with the opening in the chassis, if necessary, and then gently push the controllermodule halfway into the system.

3. Reinstall the cable management tray and recable the system, as needed.

When recabling, remember to reinstall the media converters (SFPs) if you are using fiber cables.

4. Push the controller module all the way into the chassis.

If your system is in... Then...

An HA pair The node reboots as soon as you seat the controller module completely into the chassis.

A stand-alone configuration Reconnect the power cables to the power supplies and to the power sources, and then turn on the power.

5. Firmly push the cam handle to finish seating the controller module in the system, and then push the cam handle to the closedposition.

6. Tighten the thumbscrew beneath the cam handle.

7. Check the status and firmware level of the RLM by entering the following command at the system prompt:

rlm status

8. Check the current RLM firmware level posted on the the NOW site at http://now.netapp.com/NOW/download/tools/rlm_fw/.
