Monitoring and Managing the Switch
• 03 ELP rejected by the attached switch — This switch
transmitted an ELP (exchange link protocol) frame that was
rejected by the switch at the other end of the ISL.
•
04 Incompatible switch at the other end of the
ISL
— The Interop Mode for this switch is set to Open Fabric
and the switch at the other end of the ISL is configured for
McDATA Fabric. (Refer to Configuring the Operating Mode on
page 5-4.)
•
05 External loopback adapter connected to the
port
— A loopback plug is connected to the port and there is
no diagnostic test running.
•
06 N_Port connection not allowed on this port — The
port is configured as an E_Port, but attaches to a node device.
•
07 Non-McDATA switch at other end of the ISL — The
cable is connected to a non-EMC switch and the Interop Mode
for this switch is set to McDATA Fabric.
•
08 ISL connection not allowed on this port — The port
is configured as an F_Port, but attaches to another switch.
•
10 Port binding violation - unauthorized WWN — The
WWN entered to configure port binding is not valid or a
Nickname was used that is not configured through the
Product Manager for the attached device.
•
11 Unresponsive node connected to port — Possible
causes are:
– Hardware problem on switch or on a connected node
where ELP frames are not delivered, the response is not
received, or a fabric login in (FLOGI) cannot be received.
There may be problems in the switch SBAR.
– Faulty or dirty cable connection.
– Faulty host bus adapters that do not send out an FLOGI
within a reasonable timeframe.
Reasons for segmentation include:
• Incompatible operating parameters; for example, R_A_TOV or
E_D_TOV might be inconsistent.
• Duplicate Domain IDs.
• Incompatible zoning configurations.
• Build fabric protocol error.
• No switch in fabric is capable of being principal switch.
