Data:

Three numeric values are listed:
  • The ID of the first unexpected inactive port. This ID is a decimal number.
  • The ports that are expected to be active, which is a hexadecimal number. Each bit position represents a port, with the least significant bit representing port 1. The bit is 1 if the port is expected to be active.
  • The ports that are actually active, which is a hexadecimal number. Each bit position represents a port, with the least significant bit representing port 1. The bit is 1 if the port is active.

User response

  1. If possible, use the management GUI to run the recommended actions for the associated service error code.

    • If the port has been intentionally disconnected, use the management GUI recommended action for the service error code and acknowledge the intended change.
    • Check that the SAS cable is connected at both ends and is not damaged. If necessary, replace the cable.
    • Check the switch port or other device that the cable is connected to is powered and enabled in a compatible mode. Rectify any issue. The device service interface might indicate the issue.
    • Use the remove and replace procedures to replace the adapter.
