Connecting the local systems in a MetroCluster configuration with array LUNs

The first stage in connecting the devices in a MetroCluster configuration that uses arrays LUNs is to connect a local Data ONTAP system to the fabric.

  • MetroCluster configuration planning must be complete.
  • Storage array LUNs must already be created and presented to Data ONTAP.

Use the following fabric-attached MetroCluster illustration as a reference for connecting the local systems in a MetroCluster configuration that uses array LUNs. Differences for stretch MetroCluster configurations are noted in the procedure.

This graphic is described by the surrounding text.
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 for your platform.
  1. On the local Data ONTAP system, locate the NVRAM or FC-VI interconnect module.
  2. Take one of the following actions to 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 2 in the previous illustration).
    2. Cable FC-VI Port B to the alternate fabric (Port B to Switch 1 in the previous illustration).
    3. For dual-enclosure systems, repeat substeps a and b for the bottom controllers.
    Stretch configuration with an FC-VI adapter Connect the cables between the FC-VI ports directly (point-to-point).
    Stretch configuration with an NVRAM adapter
    1. Install a copper-to-fiber converter in L01 Ph1, and cable L01 Ph1 on the local node to L01 Ph1 on the remote node.
    2. Install a copper-to-fiber converter in L02 Ph2, and cable L02 Ph2 on the local node to L02 Ph2 on the remote node.
    Dual-enclosure HA pair systems with an FC-VI adapter
    1. Connect port A of the FC-VI adapter on the top controller of the local site (vs1) to port A of the corresponding FC-VI adapter at the remote site (vs2).
    2. Connect port B of the FC-VI adapter on the top controller of the local site (vs1) to port B of the corresponding FC-VI adapter at the remote site (vs2).
    3. Repeat substeps a and b for connecting the FC-VI adapter on the bottom controller.
  3. Connect the FC initiator ports on the Data ONTAP system 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 onboard 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.
  4. Connect the Data ONTAP system to a tape backup device through a separate FC initiator port or SCSI tape adapter.
  5. Connect a console cable to the console port on the Data ONTAP system, then connect the console cable to the adapter. Use the RJ-45 to DB-9 adapter that is included with your system.
  6. 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.
  7. 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.
  8. 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.
  9. If applicable, turn on any tape backup devices.
  10. 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.
  11. 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.

Connect the remote Data ONTAP system to the fabric.
