Replacing a Controller in the StorNext QM1200, QS1200 or QS2400
Base System
Use this procedure to replace a controller in the StorNext QM1200, QS1200 or QS2400 Base System. Read through all
of the following steps in this procedure before you start to replace the controller canister.
You can determine whether you have a failed controller in two ways:
The Recovery Guru directs you to replace a failed controller.
You locate the failed controller by checking the Controller Service Action Required LED.
Before you start to replace a controller in the base system, gather antistatic protection, a new controller, and a
controller air blocker.
When you install a new controller, you must remove the battery from the failed controller, and install it in the new
controller. This procedure includes that task. If you are changing your current configuration, you might need to
replace these items:
Small Form-factor Pluggable (SFP) transceivers.
Host bus adapters or host channel adapters.
Cables – InfiniBand uses copper cable, and Fibre Channel uses copper cable or fiber-optic cable.
Preparing to Remove the Controller
1. Gather support data about your storage array by using one of these methods:
—Use the storage management software to collect and save a support bundle of your storage array. From the
Array Management Window, select Monitor >> Health >> Collect Support Data. Then name and specify a
location on your system where you want to store the support bundle.
ATTENTION Possible hardware damage – If you perform this procedure with the power turned on, the
equipment might overheat if the controller slot is left open for more than three minutes. To prevent the
possibility of overheating, you must insert the controller air blocker into the empty controller slot when you
service the controller.
ATTENTION Loss of data access – If the controller that you are replacing manages any secure volumes, the
new controller will need the correct security key to manage those volumes. After you replace the controller
and restore power to the base system, you can use the SANtricity® ES Storage Manager to import the key from
the file in which it was saved. Be sure that such a file exists and that you know the pass phrase required to
install the security key before you replace the controller.
ATTENTION Possible hardware damage – To prevent electrostatic discharge damage to the tray, use proper
antistatic protection when handling tray components.
ATTENTION Possible extended outage – You must replace the controller with the power turned on to
ensure auto-code synchronization of the native controller firmware to the new controller and to prevent the
possibility of an extended outage.

—Use the command line interface (CLI) to run the save storageArray supportData command to
gather comprehensive support data about the storage array. For more information about this command,
refer to Command Line Interface and Script Commands. Running this command can temporarily impact
performance on your storage array.
2. Did the Recovery Guru direct you to replace a failed controller?
—Yes – Go to step 3.
—No – Run the Recovery Guru to identify the failed component, and go to step 3.
3. Put on antistatic protection.
4. Unpack the new controller.
a. Set the new controller on a flat, static-free surface near the base system with the top cover up.
b. Save all the packing materials in case you need to return the controller.
Locating the Failed Controller
1. Locate the failed controller by checking the Controller Service Action Required LEDs.
2. Refer to Figure 1 for a close-up view of the controller LEDs.

2. Host Link 2 Service Action Required LED (Amber)
3. Battery Service Action Required LED (Amber)
4. Controller Service Action Allowed LED (Blue)
5. Controller Service Action Required LED (Amber)
NOTE If a fault is detected, the amber Controller Service Action Required LED is on (Figure 2). If you can safely remove the controller
canister, the blue Controller Service Action Allowed LED is on.

Pre-Work before Removing the Failed Controller
1. Label each copper cable or fiber-optic cable that is attached to the controller so that you can reconnect each
cable correctly after the new controller is installed.
2. Record the information from the seven-segment display on the rear of the base system.
The display flashes a sequence of codes. To find information about the displayed diagnostic codes, refer to
StorNext Q-Series Storage Install Guide.
Use either the GUI (first bullet) or the CLI (second bullet) to take the appropriate controller offline.
—From the Hardware pane in the Array Management Window, right-click the picture of the controller that you
want to take offline, and select Advanced >> Place >> Offline.
—Run the following command.
SMcli <DNS-network-name-or-IP-address> -c “set controller [(a | b)]
availability=offline”;
If necessary, wait for the Controller Service Action Allowed LED to come on (see Figure 2). This indication might
take several minutes for a large configuration.
3. Disconnect all of the interface cables and Ethernet cables from the failed controller.
If the storage array is running while you perform this replacement, do not disturb the second controller.
ATTENTION Potential degraded performance – To prevent degraded performance, do not twist, fold,
pinch, or step on the cables. Many cables have a minimum bending radius. For example, do not bend
fiber-optic cables tighter than a 5-cm (2-in.) radius. Check the specifications for your cables, and do not
bend any cable tighter than the minimum specified radius.

Removing the Failed Controller
1. Prepare the controller air blocker (Figure 3) by removing it from its packaging and folding it inward at right angles
so it is ready to insert into the open controller slot.

2. Remove the failed controller (Figure 4).
a. Unlock and pull out the release lever to release the controller.
b. Using the release lever and your hands, pull the controller out of the base system.

3. Set the failed controller on a flat, static-free surface with the release levers up.
4. Insert the controller air blocker (Figure 5) into the open controller slot to make sure that correct airflow is
maintained.
ATTENTION Possible equipment damage – The controller slot cannot remain open for more than three
minutes because of the possibility of overheating the equipment. The controller air blocker fills the
controller slot so that the equipment will not overheat.

side guide pins to correctly seat it against the back surface of the controller.
6. Engage the latch to secure the battery circuit board in the new controller card.
7. Reinstall the top cover on the new controller by sliding it forward until the top cover latch buttons click.
Installing a Controller in the StorNext QM1200, QS1200 or QS2400 Base System
1. Remove the controller air blocker from the controller slot.
2. Slide the new controller (Figure 8) all the way into the base system. 

ATTENTION Make sure that the battery is fully seated and that the connectors are fully seated. If the
battery is not correctly seated, you cannot reinstall the top cover on the controller canister as directed
later. To make sure that the controller battery is seated correctly, you might need to slide it out and insert
it again. You know it is secure when you hear it click into place, and the locking handle does not move out
of its upright position when you wiggle it.
