OceanStor 5300 V3, 5500 V3, 5600 V3, 5800 V3, and 6800 V3 Storage System V300R003

Routine maintenance activities are the most common activities for the storage device, including powering on or off the storage device, managing users, modifying basic parameters of the storage device, and managing hardware components. This document applies to the system administrators who are responsible for carrying out routine maintenance activities, monitoring the storage device, and rectifying common device faults.

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 preserve proper communication between them.

Context

Note the following before modifying 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 the application server may fail.
  • When two storage devices connect to each other through Fibre Channel ports, ensure that the rates of the Fibre Channel ports on both the storage devices are the same. Otherwise, the communication between the storage devices may fail.
  • Because modifying the Fibre Channel ports interrupts the communication between the storage device and the application server, do not modify any Fibre Channel port settings when there are services running on the storage device.

Procedure

  1. Log in to DeviceManager.
  2. Choose System.
  3. Select the controller enclosure where the Fibre Channel port resides.
  4. Click to switch to the rear view.
  5. Click the Fibre Channel port whose information you want to modify.

    The FC Port dialog box is displayed.

  6. Click Modify.

    NOTE:
    You can also click Properties to view general properties and owning port group of the Fibre Channel port as well as modify the parameters of the Fibre Channel port.


  7. 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 the application server may fail.
    • When two storage devices connect to each other through Fibre Channel ports, ensure that the rates and modes of the Fibre Channel ports on both the storage devices are the same. 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 configured maximum rate of the Fibre Channel port is 4 Gbit/s, you can set the value to be 2 Gbit/s or 4 Gbit/s.
    • If the configured maximum rate of the Fibre Channel port is 8 Gbit/s, you can set the value to be 2 Gbit/s, 4 Gbit/s, or 8 Gbit/s.
    • If the configured maximum rate of the Fibre Channel port is 16 Gbit/s, you can set the value to be 4 Gbit/s, 8 Gbit/s, or 16 Gbit/s.
    • If the configured rate of the Fibre Channel port is Autonegotiation, the rate of the Fibre Channel port is adaptive to that of the peer Fibre Channel port. If the adaptive rates do not match, change the port rate to another value.

  8. Confirm the Fibre Channel port modification.
    1. Click Apply.

      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.
