Updating your hardware

Hardware slot assignments

When upgrading your hardware, you might need to add the following to your filers and disk shelves:

One or more additional FC-AL adapters to your filers
One cluster interconnect adapter card per filer
Additional LRC adapters for the Channel B loops of your disk shelves

You might have to move or remove other adapters when adding the appropriate FC-AL adapters. You should have a minimum of one FC-AL adapter for your Channel A loops. See the F700 Series Field Service Guide for information about slot assignments.

The following diagram illustrates the possible location for cards in your filers. For current information about slot assignments for your filers, see NOW at http://now.netapp.com.

Filer	Slot
	1	2	3	4	5	6	7	8	9
F740	32-bit FC-AL/NIC					32-bit FC-AL/ Gb Ethernet		Cluster interconnect adapter	NVRAM
F760	32-bit FC-AL			Gb Ethernet
	32-bit FC-AL/NIC				SCSI tape	32-bit FC-AL/ Gb Ethernet

Note
You need Data ONTAP 5.3 software or later if you want to install a tape adapter or use four GbE adapters in expansion slot 5.

Installing additional hardware in your filers and disk shelves

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

Step	Action
1	If your filers are running, shut down the filers from the console, using the `halt` command: halt
2	Ground yourself to the filer chassis using the antistatic grounding strap, then turn off the power to the filers and disk shelves.
3	Install and label additional FC-AL cards, as described in the F700 Series Field Service Guide. Make sure that you label the FC-AL cards appropriately. Note Each FC-AL interface on your filers can connect to a maximum of eight daisy-chained disk shelves. The distribution of the storage capacity for a filer with two or more FC-AL interfaces is left to your discretion. See Appendix A, Cluster Configuration Examples, for examples of labeling the FC-AL interfaces.
4	Install the cluster interconnect adapters as described in the F700 Series Field Service Guide.
5	Install any LRC cards as needed, as described in the appropriate fibre channel disk shelf guide. If you have a Fibre Channel StorageShelf FC7, you might have to label your LRC cards as well: Label the LRC card above the EDM card as Channel A. Label the LRC card below the EDM card as Channel B.
6	Repeat Steps 1 through 5 on the partner filer.
7	Go to Cabling your system into a cluster.
