Modifying a Fibre Channel Port

Modifying a Fibre Channel Port

When the networking mode between a storage device and an application server changes, modify the settings of Fibre Channel ports to ensure normal communication between them.

Context

Note the following when you modify Fibre Channel ports:

  • If a storage device connects to an application server through a Fibre Channel port, ensure that the rate of the Fibre Channel port on the storage device is the same as that of the peer host bus adapter (HBA) port on the application server. Otherwise, the communication between the storage device and application server may fail.
  • If two storage devices connect to each other through Fibre Channel ports, ensure that the rates of the Fibre Channel ports on both storage devices are the same. Otherwise, the communication between the storage devices may fail.
  • Modifying Fibre Channel port settings interrupts communication between a storage device and an application server or between storage devices. Ensure that the storage devices are not carrying any services before making any modifications.

Procedure

  1. Log in to DeviceManager.
  2. Choose Provisioning > Port > FC Ports.
  3. Select a Fibre Channel port and click Properties.
  4. In Configured Rate (Gbit/s), select a data transfer rate for the Fibre Channel port.

    • The rate and mode of the Fibre Channel port on a storage device must be consistent with those of the peer Fibre Channel HBA port on the application server. Otherwise, the communication between the storage device and application server may fail.
    • The rate and mode of the Fibre Channel ports on two storage systems that are connected to each other must be consistent. Otherwise, the communication between the storage devices may fail.

    Available rates of a Fibre Channel port are 2 Gbit/s, 4 Gbit/s, 8 Gbit/s, 16 Gbit/s, and Autonegotiation. Select a value after obtaining the rate of the peer Fibre Channel port.

    NOTE:
    • If the maximum rate of the port is 4 Gbit/s, you can select 2 Gbit/s or 4 Gbit/s.
    • If the maximum rate of the port is 8 Gbit/s, you can select 2 Gbit/s, 4 Gbit/s, or 8 Gbit/s.
    • If the maximum rate of the port is 16 Gbit/s, you can select 4 Gbit/s, 8 Gbit/s, or 16 Gbit/s.

  5. Confirm the Fibre Channel port modification.

    1. Click OK.

      The security alert dialog box is displayed.

    2. Confirm the information in the dialog box and select I have read and understand the consequences associated with performing this operation.
    3. Click OK.

      The Success dialog box is displayed, indicating that the operation succeeded.

    4. Click OK.
