After ensuring that the system meets all the requirements in the Preparing for the installation section, you can install your new system.
- Connect the Ethernet management 1 port on each bridge to your network using an Ethernet cable.
Note: The Ethernet management 1 port enables you to quickly download the bridge firmware (using ATTO ExpressNAV or FTP management interfaces) and to retrieve core files and extract logs.
- Configure the Ethernet management 1 port for each bridge by following the procedure in the ATTO FibreBridge 6500N Installation and Operation Manual, section 2.0.
Note: When running QuickNAV to configure an Ethernet management port, only the Ethernet management port that is connected by the Ethernet cable is configured. For example, if you also wanted to configure the Ethernet management 2 port, you would need to connect the Ethernet cable to port 2 and run QuickNAV.
- Configure the bridges.
Be sure to make note of the user name and password that you designate.
- Configure the bridge name.
The bridges should each have a unique name within the MetroCluster configuration.
- Configure the data rate/speed of the bridge FC ports.
- Configure the connection mode that the bridges use to communicate across the FC network.
You must set the bridge connection mode to ptp (point-to-point).
For example, if you were to use the command line interface (CLI) to set the bridge FC 1 port's basic required configuration, you would enter the following commands; the last command saves the configuration changes: set ipaddressset subnetset ipgatewayset FCDataRate 1 8Gbset FCConnMode 1 ptpset SNMP enabledset bridgenameSaveConfiguration
Note: To set the IP address without the Quicknav utility, you need to have a serial connection to the FibreBridge.
Result: You are prompted to restart the bridge.
The ATTO FibreBridge 6500N Installation and Operation Manual has the most current information on available commands and how to use them.
- Update the firmware on each bridge to the latest version by following the instructions—starting with Step 4—on the FibreBridge 6500N Download page.
- Cable the disk shelves to the bridges by completing the following substeps:
- Daisy-chain the disk shelves in each stack.
For information about daisy-chaining disk shelves, see the Installation and Service Guide for your disk shelf model.
- For each stack of disk shelves, cable IOM A square port of the first shelf to SAS port A on FibreBridge A.
- For each stack of disk shelves, cable IOM B circle port of the last shelf to SAS port A on FibreBridge B.
Each bridge has one path to its stack of disk shelves; bridge A connects to the A-side of the stack through the first shelf, and bridge B connects to the B-side of the stack through the last shelf.
Note: The bridge SAS port B is disabled.
The following illustration shows a set of bridges cabled to a stack of three disk shelves:
- Verify that each bridge can detect all disk drives and disk shelves it is connected to.

| ATTO ExpressNAV GUI
- In a supported web browser, enter the IP address of a bridge in the browser box.
You are brought to the ATTO FibreBridge 6500N home page, which has a link.
- Click the link and enter your user name and the password that you designated when you configured the bridge.
The ATTO FibreBridge 6500N status page appears with a menu to the left.
- Click Advanced in the menu.
- Enter the following command, and then click Submit:sastargets

||Enter the following command:sastargets
The output shows the devices (disks and disk shelves) that the bridge is connected to. Output lines are sequentially numbered so you can quickly count the devices. For example, the following output shows that 10 disks are connected.

Note: If the text response truncated appears at the beginning of the output, you can use Telnet to connect to the bridge and enter the same command to see all the output.
- Verify the command output shows the bridge is connected to all disks and disk shelves in the stack that it is supposed to be connected to.

||Repeat step 6 for each remaining bridge.
- Check for loose SAS cables or correct the SAS cabling by repeating step 5.
- Repeat step 6.
- Cable each bridge in the first switch fabric to the FC switches:
This illustration shows Brocade switches.
This illustration shows Cisco switches.
The Brocade and Cisco switches use different port numbering:
- On Brocade switches, the first port is numbered “0”
- On Cisco switches, the first port is numbered “1”
This is reflected in the following table:
|Cable this bridge...
||To this port on FC_switch_x_1...
| bridge_A_1_port number
| bridge_A_1_port number
- Repeat the previous step on the bridges at the partner site.
