Updating your hardware

About updating your hardware

When updating your hardware, you might need to add the following to your nodes and disk shelves:

One or more FC-AL or dual Fibre Channel adapters to your nodes
One cluster interconnect adapter per node. See Cluster cabling differences for a description of the cluster interconnect adapters
Additional LRCs for your FC7, FC8, or FC9 disk shelves
Additional disk shelves to your system
Two ESH modules per disk shelf to replace the LRC modules, if upgrading DS14 or DS14mk2 FC disk shelves with LRC modules

You might have to move or remove other adapters when adding the appropriate FC-AL adapters. See the F800 Series Field Service Guide for information about installing additional FC-AL adapters.

Before installing additional hardware into your nodes or disk shelves, check the NOW Web page at http://now.netapp.com for current configuration information.

Mixed disk shelf environment requirements

When converting your filers into a cluster, you can add new disk shelves to your existing disk shelf loops. In certain instances, you add newer disk shelf types to older disk shelf types.

To successfully add newer disk shelves to older, existing disk shelves, you must be aware of the following requirements:

If you have both FC9 and FC7 disk shelves, you must assign an FC7 disk shelf as disk shelf 0, the first physical disk shelf in the loop.
If you are converting filers that have both DS14 and FC9 or FC8 disk shelves, you must assign a DS14 disk shelf as the last physical disk shelf in the Channel A and B loops.
If you have both DS14 and FC7 disk shelves, you must assign an FC7 disk shelf as disk shelf 0, the first physical disk shelf in the loop, and a DS14 disk shelf as the last physical disk shelf in the Channel A and B loops.
If you are converting filers that have FC9 disk shelves and want to use dual Fibre Channel adapters, you must use an MIA (media interface adapter) in the Channel A and B Input ports of the first disk shelf in each loop.
You cannot use dual Fibre Channel adapters with FC7 or FC8 disk shelves.
If you have a DS14/DS14mk2 FC with ESH modules, all your disk shelves in that loop must have ESH modules.

Installing additional hardware

To install the hardware you need for clustering, complete the following steps.

Note
You should run diagnostics for any new components you add to your cluster. See the Diagnostics Guide for more information.

Step	Action
1	Shut down the filers by entering the following command: halt
2	Ground yourself using the antistatic grounding strap, then turn off the power to the filers and disk shelves and unplug them.
3	Install and label additional FC-AL adapters or dual Fibre Channel adapters, as described in the F800 Series Field Service Guide. Make sure to label the FC-AL adapters appropriately. See the System Configuration Guide for information about the maximum number of drives supported by a loop.
4	Install the appropriate cluster interconnect adapter, as described in the F800 Series Field Service Guide.
5	If you have...	Then...
	DS14 or DS14mk2 FC disk shelves with LRCs and you are converting to ESH modules	Replace the LRC modules with ESH modules. See the DiskShelf14 and DiskShelf14mk2 FC Hardware Guide for installation instructions.
	DS14 or DS14mk2 FC disk shelves and are not changing LRC for ESH modules	Go to Step 6.
	FC7, FC8, or FC9 disk shelves	Install any LRCs, as needed. If you have an FC7, you might have to label your LRCs. If the LRCs are not labeled, label them as follows: Label the LRC above the EDM card as Channel A. Label the LRC below the EDM card as Channel B.
6	Repeat Steps 3 through 5 on the partner node.
7	Go to Updating your software.
