Preparing for the installation

When you are preparing to install the FC-to-SAS bridges as part of your new MetroCluster system, you must ensure that your system meets certain requirements, including meeting setup and configuration requirements for the bridges. Other requirements include downloading the necessary documents, the ATTO QuickNAV utility, and the bridge firmware.

Before you begin

Your system must already be installed in a rack if it was not shipped in a system cabinet.
Your system must be using supported disk shelves and firmware for your version of Data ONTAP.
NetApp Interoperability Matrix Tool
Your ATTO bridge must be running supported firmware for your version of Data ONTAP.
NetApp Interoperability Matrix Tool
Your configuration must meet all configuration requirements for the bridge.
NetApp Interoperability Matrix Tool
Each FC switch must have one FC port available for one bridge to connect to it.
The computer you are using to set up the bridges must be running an ATTO-supported web browser to use the ATTO ExpressNAV GUI.
The ATTO-supported web browsers are Internet Explorer 8 and 9, and Mozilla Firefox 3.

The ATTO Product Release Notes have an up-to-date list of supported web browsers. You can access this document from the ATTO web site as described in the following steps.

Steps

Download the following documents:
- SAS Disk Shelves Installation and Service Guide for DS4243, DS2246, DS4486, and DS4246
Download content from the ATTO website and from the NetApp website:
1. From NetApp Support, navigate to the ATTO FibreBridge Description page by clicking Software, scrolling to Protocol Bridge, choosing ATTO FibreBridge from the drop-down menu, clicking Go!, and then clicking View & Download.
2. Access the ATTO web site using the link provided and download the following:
  - ATTO FibreBridge 6500N Installation and Operation Manual
  - ATTO QuickNAV utility (to the computer you are using for setup)
3. Go to the ATTO FibreBridge 6500N Firmware Download page and do the following:
  - Navigate to the ATTO FibreBridge 6500N Firmware Download page by clicking Continue at the end of the ATTO FibreBridge Description page.
  - Download the bridge firmware file using Steps 1 through 3 of that procedure.
    You update the firmware on each bridge later in this procedure.
  - Make a copy of the ATTO FibreBridge 6500N Firmware Download page and release notes for reference when you are instructed to update the firmware on each bridge.
Gather the hardware and information needed to use the recommended bridge management interfaces, the ATTO ExpressNAV GUI, and the ATTO QuickNAV utility:
1. Acquire a standard Ethernet cable (which connects from the bridge Ethernet management 1 port to your network).
2. Determine a non-default user name and password (for accessing the bridges).
  You should change the default user name and password.
3. Obtain an IP address, subnet mask, and gateway information for the Ethernet management 1 port on each bridge.
4. Disable VPN clients on the computer you are using for setup.
  Active VPN clients cause the QuickNAV scan for bridges to fail.
