Replacing LRC modules with ESH2 modules in a disk shelf

Verify that your NetApp appliance meets the minimum software requirements to support the disk shelf and module combination. See the System Configuration Guide at http://now.netapp.com for more information.

If you are converting modules in a...

Then...

FAS270 system

Power off your system and go to Step 6.

FAS270c system

Select which node/loop you want to convert first; A or B. For the sake of clarity, let's convert node/loop B in the following steps.

From the node A console, enter the following command and observe the output:

cf enable

Result

Takeover of node B is enabled on node A.

Enter the following command from the node A console:

cf takeover

Result

Node A takes over node B and gives the following output:

takeover completed

Make sure that node A can access both node B and node A disks.

Put on the antistatic wrist strap and grounding leash.

Disconnect the LRC modules from the Fibre Channel cabling on all disk shelves in the B loop, and remove the cabling from the system.

Unlatch all LRC modules in the B loop.

Using the thumb and index finger of both hands, press the levers on the CAM mechanism on the module to release it.

Pull all LRC modules in the B loop out of the disk shelf and set them aside.

Install all replacement ESH2 modules into the B loop of the disk shelves.

For each module, push apart the levers on the CAM mechanism and slide the replacement ESH2 module into the slot at the rear of the disk shelf, then push the levers of the CAM mechanism into place.

Caution
Do not use excessive force when sliding the module into the disk shelf; you might damage the connector.

Plug the optical SFP into the input port on the ESH2 modules if they are not already plugged in.

Connect all ESH2 modules to your storage appliance.

Note
You need to replace the LRC cabling with the proper HSSDC2-to-SFP cabling for ESH2 modules. See the DiskShelf14 and DiskShelf14mk2 FC Hardware Guide for more information.

If you converted modules for a...

Then...

FAS270 system

Turn on the power and reboot the system.

FAS270c system

Give back the partner node by entering the following command:

cf giveback

Result

The local node releases the partner node, which reboots and resumes normal operation. The following message is displayed on the console when the process is complete:

giveback completed

On FAS270c systems, repeat Step 3 through Step 13 for the second node/loop.
