Replacing a Failed Controller Canister in the E5660 Controller-
Drive Tray
To access this product, go to the NetApp® support site at mysupport.netapp.com.
You can determine whether you have a failed controller canister in two ways:
The Recovery Guru directs you to replace a failed controller canister.
The amber Controller Service Action Required LED indicates a failed controller canister.
Before you replace the controller canister, gather antistatic protection, a new controller canister, 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.
ATTENTION Possible loss of data access – Your new controller must have the same host interface card (HIC)
as the controller you are replacing. If the HICs do not match, do not attempt this procedure. The presence of mis-
matched controllers causes your storage array to lock down when you bring the new controller on line. You lose
access to your data until the problem is corrected.
ATTENTION Possible loss of data access – If the controller that you are replacing manages any secure volumes,
the new controller needs the correct security key to manage those volumes. After you replace the controller and
restore power to the controller-drive tray, you can use SANtricity® Storage Manager to load 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 – Because 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 controller slot when you service the controller.

Tray
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.
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 toolbar, select Monitor > Health > Collect Support Data Manually. Then
name and specify a location on your system where you want to store the support bundle.
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 the current version of the Command Line Interface and Script
Commands Programming Guide.

NOTE Gathering support data can temporarily impact performance on your storage array.
2. Did the Recovery Guru direct you to replace a failed controller canister?
Yes – Go to step 3.
No – Run the Recovery Guru to identify the failed controller canister, and then go to step 3.
3. Locate the failed controller canister by checking the Controller Service Action Required LEDs shown in the
following figure.
If a fault is detected, the amber Controller Service Action Required LED is on. You can safely remove the
controller canister when the blue Controller Service Action Allowed LED is on.
NOTE Your controller canister might have a different number and type of host interface connectors than what is
shown in the following figure.

3. Seven-Segment Display
4. Record the information from the seven-segment display on the rear of the controller-drive tray.
The display flashes a sequence of codes. To find information about the displayed diagnostic codes, refer to the
E5600 Controller-Drive Tray and Related Drive Trays Installation Guide.
5. Is the Controller Service Action Allowed LED to on?
Yes – Go to step 8.
No – Go to step 6.
6. 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 then select Advanced > Place > Offline.
Run the following command:
smCLI <DNS-network-name-or-IP-address> -c
“set controller [(a | b)] availability=offline”;
7. Wait for the Controller Service Action Allowed LED to come on.
This indication might take several minutes for a large configuration.
8. Put on antistatic protection.

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. Check the specifications for your cables,
and do not bend any cable more tightly than the minimum specified radius.
9. Label each of the interface cables and Ethernet cables attached to the controller canister so that you can
reconnect each cable correctly after you reinstall the controller canister.
10.Disconnect all of the interface cables and Ethernet cables from the failed controller canister without disturbing the
other canister.
11.If the failed controller canister contains a Fibre Channel HIC or an InfiniBand HIC, remove the small form-factor
pluggable (SFP) transceivers (for Fibre Channel) or quad SFP (QSFP) transceivers (for InfiniBand) from the HIC
and save them for possible reuse.
12.Prepare the controller air blocker by removing it from its packaging and folding it inward at right angles so it is
ready to insert into the open controller slot.
Figure 3. Controller Air Blocker
13.Remove the failed controller canister.
NOTE The following figures show the controller in the bottom position within the controller-drive tray. However,
you might be removing the controller and inserting the controller air blocker in the top position. The required
actions are similar.
a. Unlock and pull out the release levers to release the controller canister.

b. Using the release levers and your hands, pull the controller canister out of the controller-drive tray.

c. Set the failed controller canister on a flat, static-free surface with the release levers up.
ATTENTION Possible hardware damage – Because 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 controller slot when servicing the controller.

15.Remove the battery from the failed controller canister by performing these steps:
a. Press down on both of the top cover latch buttons as you slide the top cover off the controller canister.
