Connecting the remote systems in a MetroCluster configuration with array LUNs

After connecting the local Data ONTAP systems to the fabric, you need to connect the remote systems to the fabric.

The local Data ONTAP systems must be connected to the fabric.

Use the following illustration of a fabric-attached MetroCluster configuration as a reference for connecting the remote Data ONTAP systems. Differences for stretch MetroCluster configurations are noted in the procedure.

Note: A port pair consists of two FC initiator ports that are used to access the same set of array LUNs. For example, FC initiators 0a and 0d are accessing the same LUNs. See the FlexArray Virtualization Installation Requirements and Reference Guide for specific information about port pairs.

  1. Connect the local Data ONTAP system to the remote Data ONTAP system.
    For a... Do this...
    Fabric-attached configuration
    1. Cable FC-VI Port A to one fabric (Port A to Switch 4 in the sample illustration).
    2. Cable FC-VI Port B to the alternate fabric (Port B to Switch 3 in the sample illustration).
    Stretch configuration with an FC-VI card Use a point-to-point connection.
  2. Connect the FC initiator ports to the switched fabric:
    1. Identify one of the two FC initiator port pairs on the Data ONTAP system.
    2. Cable one port of the FC initiator port pair to one fabric.
    3. Cable the other port of the pair to the alternate fabric. In the sample illustration, these are ports 0a and 0b.
    4. Identify the other FC initiator port pair on the Data ONTAP system.
    5. Cable one port of the pair to one fabric.
    6. Cable another port of the pair to the alternate fabric. In the sample illustration, these are ports 0c and 0d.
  3. Connect the Data ONTAP system to a tape backup device through a separate FC initiator port or SCSI tape adapter.
  4. Connect a console cable to the console port on the Data ONTAP system. Use the RJ-45 to DB-9 adapter that is included with your system. Connect the console cable to the adapter.
  5. Install the cable management tray.
    1. Pinch the arms of the tray and fit the holes in the arms through the motherboard tray pins.
    2. Push the cables into the cable holders, thread the adapter cables through the top rows of the cable holders, and then thread the port cables through the lower cable holders.
  6. Connect the Data ONTAP system to the Ethernet network by plugging the network cable into the networking port. If you are connecting more than one network cable to the network, connect to the ports sequentially. Use the cable management tray to direct all the cabling from your system.
  7. Connect the remote management device from the back of the Data ONTAP system to the network using an Ethernet cable. The network switch port for the remote management device connection must negotiate down to 10/100 or autonegotiate.
  8. If applicable, turn on any tape backup devices.
  9. For each power supply on the Data ONTAP system, take the following steps:
    1. Ensure that the power switch is in the Off (0) position.
    2. Connect the socket end of the power cord to the power plug on the power supply.
    3. Secure the power cord with the retaining adjustable clip on the power supply.
    4. Plug the other end of the power cord into a grounded electrical outlet.
      Note: To obtain power supply redundancy, you must connect the second power supply to a separate AC circuit.
  10. Start a communications program. You must use some form of communications program to perform initial network setup and configuration of the Data ONTAP system. You can start a communications program through the remote management device or through the console after connecting to the serial port.
