Configuring the Cisco FC switches

You must configure each Cisco switch in the MetroCluster configuration.

About this task

The following requirements apply to the Cisco FC switches: The following requirements apply to the Inter-Switch Link (ISL) connections: The following requirements apply to the storage connections:

Steps

  1. Reviewing Cisco license requirements
    Certain feature-based licenses might be required for the switches in a MetroCluster configuration. These licenses enable you to use features such as QoS or long-distance mode credits on the switches. You must install these licenses on all four switches in a MetroCluster configuration.
  2. Setting the Cisco FC switch to factory defaults
    To ensure a successful configuration, you must set the switch to its factory defaults. This ensures that the switch is starting from a clean configuration.
  3. Configure the Cisco FC switch basic settings and community string
    You must specify the basic settings with the setup command or after issuing the reload command.
  4. Acquiring licenses for ports
    You do not have to use Cisco switch licenses on a continuous range of ports; instead, you can acquire licenses for specific ports that are used and remove licenses from unused ports. You should verify the number of licensed ports in the switch configuration and, if necessary, move licenses from one port to another as needed.
  5. Enabling ports in a Cisco MDS 9148 switch
    In Cisco MDS 9148 switches, you must manually enable the ports required in a MetroCluster configuration.
  6. Configuring the F-ports on a Cisco FC switch
    You must configure the F-ports on the FC switch. In a MetroCluster configuration, the F-ports are the ports that connect the switch to the HBA initiators, FC-VI interconnects and FC-to-SAS bridges. Each port must be configured individually.
  7. Assigning buffer-to-buffer credits to F-Ports in the same port group as the ISL
    You must assign the buffer-to-buffer credits to the F-ports if they are in the same port group as the ISL. If the ports do not have the required buffer-to-buffer credits, the ISL could be inoperative. This task is not required if the F-ports are not in the same port group as the ISL port.
  8. Creating and configuring the VSANs on Cisco FC switches
    You must create a VSAN for the FC-VI ports and a VSAN for the storage ports on each FC switch in the MetroCluster configuration. The VSANs should have a unique number and name. You must do additional configuration if you are using two ISLs with in-order delivery of frames.
  9. Configuring the E-ports on the Cisco FC switch
    You must configure the FC switch ports that connect the ISL. These are the E-ports, and configuration must be done for each port. To do so, the correct number of buffer-to-buffer credits (BBCs) must be calculated.
  10. Configuring zoning on a Cisco FC switch
    You must assign the switch ports to separate zones to isolate storage (HBA) and controller (FC-VI) traffic.
  11. Ensuring the FC switch configuration is saved
    You must make sure the FC switch configuration is saved to the startup config on all switches.
