E-Series

Adding, Upgrading, or Replacing Host Interface Cards in E5700

Controller Shelves

You can add host interface cards (HICs) to E5700 controller shelves that only have baseboard host ports. Adding HICs allows

you to increase the number of host ports in your storage array and can provide additional host protocols. When you add HICs,

you must power off the storage array, install the HIC, and reapply power.

Before you begin

• The HICs must be compatible with your controllers.

Attention: Possible loss of data access – Never install a HIC in an E5700 controller canister if that HIC was designed for

another E-Series controller. In addition, both controllers and both HICs must be identical. The presence of incompatible or

mismatched HICs will cause the controllers to lock down when you apply power.

• You have all cables, transceivers, switches, and host bus adapters (HBAs) needed to connect the new host ports.

Note: For information about compatible hardware, refer to the

NetApp Interoperability Matrix Tool

and the

NetApp

Hardware Universe

• You have an ESD wristband, or you have taken other antistatic precautions.

• You have a #1 Phillips screwdriver.

• You have labels to identify the new host cables.

• You have installed SANtricity Storage Manager on a management station, so you can use the storage array's command line

interface (CLI).

Note: If this software has not yet been installed, follow the instructions in the

SANtricity Power Guide for Advanced Users

for your operating system to download and install it.

• You have scheduled a downtime maintenance window for this procedure. The power must be off when you install HICs, so

you will not be able to access data on the storage array until you have successfully completed this procedure.

About this procedure

Use this procedure to add a HIC to a controller canister that has baseboard ports only. This procedure applies to following

controller shelves:

• E5724 controller shelf

Preparing to add host interface cards

Before adding HICs to E5700 controller shelves, you must perform a number of steps using SANtricity System Manager and

SANtricity Storage Manager to prepare your system. You must back up the storage array's configuration database, collect

support data, and stop host I/O operations. You must also power down the controller shelf.

Steps

1. From the home page of SANtricity System Manager, ensure that the storage array has Optimal status.

If the status is not Optimal, use the Recovery Guru or contact technical support to resolve the problem. Do not continue with

this procedure.

2. Back up the storage array's configuration database.

If a problem occurs when you remove a controller, you can use the saved file to restore your configuration.

a. Open the Enterprise Management Window (EMW) for SANtricity Storage Manager on your management station.

b. Select the storage array.

c. Select Tools > Execute Script.

d. Type the following command in the text box.

save storageArray dbmDatabase sourceLocation=onboard contentType=all file="filename";

In this command, filename is the file path and file name to which you want to save the database. Enclose the file name

in double quotation marks (" "). For example:

file="C:\Program Files\CLI\logs\dbmdata.zip"

Preparing to add host interface cards 3

This command does not automatically append a file extension to the saved file. You must specify a file extension when

entering the file name.

e. Select Tools > Verify and Execute.

3. Collect support data for your storage array.

Collecting support data before and after replacing a component ensures you can send a full set of logs to technical support in

case the replacement does not resolve the problem.

Option Description

SANtricity System Manager a. Select Support > Support Center > Diagnostics.

b. Select Collect Support Data.

c. Click Collect.

The file is saved in the Downloads folder for your browser with the name support-

data.7z.

Script editor in the EMW a. Open the Enterprise Management Window (EMW) in SANtricity Storage Manager on

your local host.

b. Select the storage array.

c. Select Tools > Execute Script.

d. Type the following command in the text box.

save storageArray supportData file="filename";

In this command, filename is the file path and the file name to which you want to save

the support data. Enclose the file path and the file name in double quotation marks (" ").

For example:

file="C:\Program Files\CLI\logs\support-data.7z"

e. Select Tools > Verify and Execute.

4. Ensure that no I/O operations are occurring between the storage array and all connected hosts. For example, you can perform

these steps:

• Stop all processes that involve the logical unit numbers (LUNs) mapped from the storage to the hosts.

• Ensure that no applications are writing data to any LUNs mapped from the storage to the hosts.

• Unmount all file systems associated with any LUNs mapped from the storage to the hosts.

Note: The exact steps to stop host I/O operations depend on the host operating system and the configuration, which are

beyond the scope of these instructions. If you are not sure how to stop host I/O operations in your environment, consider

shutting down the host.

Attention: Possible data loss – If you continue this procedure while I/O operations are occurring, the host application

might lose data because the storage array will not be accessible.

5. If the storage array participates in a mirroring relationship, stop all mirroring I/O operations between the primary and

secondary storage arrays.

6. Wait for any data in cache memory to be written to the drives.

The green Cache Active LED on the back of each controller is on when cached data needs to be written to the drives. You

must wait for this LED to turn off.

7. Wait for all operations to complete before continuing with the next step.

8. From the Home page of SANtricity System Manager, select View Operations in Progress.

9. Power down the controller shelf.

a. Turn off both power switches on the controller shelf.

b. Wait for all LEDs on the controller shelf to turn off.

Removing a controller canister

When you remove a controller canister, you must disconnect all cables. Then, you can slide the controller canister out of the

controller shelf.

Steps

1. Put on an ESD wristband or take other antistatic precautions.

2. Label each cable that is attached to the controller canister.

3. Disconnect all of the cables and remove SFPs from the controller canister.

Attention: To prevent degraded performance, do not twist, fold, pinch, or step on the cables.

4. Using two hands and the cam handle, slide the controller canister out of the shelf.

Attention: Always use two hands to support the weight of a controller canister.

If you are removing the controller canister from an E5724 controller shelf, a flap swings into place to block the empty bay,

helping to maintain air flow and cooling.

5. Turn the controller canister over, so that the removable cover faces up.

6. Place the controller canister on a flat, static-free surface.

Installing a host interface card

After removing the controller canister and HIC faceplate, you can install a HIC and re-attach the HIC faceplate.

Steps

1. Unpack the new HIC and the new HIC faceplate.

2. Press the button on the cover of the controller canister, and slide the cover off.

3. Confirm that the green LED inside the controller (between the battery and the DIMMs) is off.

If this green LED is on, the controller is still using battery power. You must wait for this LED to go off before removing any

components.

4. Using a #1 Phillips screwdriver, remove the screws that attach the HIC faceplate to the controller canister.

There are four screws: one on the top, one on the side, and two on the front.

5. Remove the HIC faceplate.

6. Align the three thumbscrews on the HIC with the corresponding holes on the controller, and align the connector on the

bottom of the HIC with the HIC interface connector on the controller card.

Be careful not to scratch or bump the components on the bottom of the HIC or on the top of the controller card.

7. Carefully lower the HIC into place, and seat the HIC connector by pressing gently on the HIC.

Attention: Possible equipment damage – Be very careful not to pinch the gold ribbon connector for the controller LEDs

between the HIC and the thumbscrews.

9. Using a #1 Phillips screwdriver, attach the new HIC faceplate to the controller canister with four screws.

10. Reinstall the cover on the controller canister by sliding the cover from back to front until the button clicks.

11. Set the controller canister aside until you are ready to install it.

Installing a controller canister

After installing the new HIC, you can reinstall the controller canister into the controller shelf.

Steps

1. Turn the controller canister over, so that the removable cover faces down.

2. With the cam handle in the open position, slide the controller canister all the way into the controller shelf.

The following figure is an example of an E5724 controller shelf:

3. Move the cam handle to the left to lock the controller canister in place.

4. Install the SFPs in the host ports on the controller, and reconnect all of the cables.

If you are using more than one host protocol, be sure to install the SFPs in the correct host ports.

5. If you are adding HICs to a duplex configuration, repeat all steps to remove the second controller canister, install the second

HIC, and replace the second controller canister.

After adding a host interface card

After adding a HIC, you might need to perform additional steps before attaching data cables. For the additional steps you must

check the controller LEDs and seven-segment display and confirm that the controller's status is Optimal.

Before you begin

You have installed any new host hardware needed for the new host ports, such as switches or host bus adapters (HBAs).

Steps

1. Turn on the two power switches at the back of the controller shelf.

• Do not turn off the power switches during the power-on process, which typically takes 90 seconds or less to complete.

• The fans in each shelf are very loud when they first start up. The loud noise during start-up is normal.

2. As the controller boots, check the controller LEDs and seven-segment display.

• The seven-segment display shows the repeating sequence OS, Sd, blank to indicate that the controller is performing

Start-of-day (SOD) processing. After a controller has successfully booted up, its seven-segment display should show the

tray ID.

• The amber Attention LED on the controller turns on and then turns off, unless there is an error.

• The green Host Link LEDs remain off until you connect the host cables.

Note: The figure shows an example controller canister. Your controller might have a different number and a different type

of host ports.
