Event code: 081
Message:
Invalid attachment.
Severity:
Informational.
Explanation:
A switch port recognized an incompatibility with the attached fabric element or device and isolated the port. An
isolated port does not transmit Class 2, Class 3, or Class F traffic. Refer to event data for the reason.
Action:
Action depends on reason specified.
Event data:
The first byte of event data (byte 0) specifies the port number. The fifth byte (byte 4) specifies the isolation reason
as follows:
1 = Unknown - Reason is unknown, but probably caused by failure of an E_Port connected device. Fault isolate
the failed device or contact support personnel to report the problem.
2 = ISL connection not allowed - The port connection conflicts with the configured port type. Change the port
type to F_Port if the port is cabled to a device, or E_Port if the port is cabled to a fabric element to form an ISL.
3 = Incompatible switch - The switch returned a Process ELP Reject - Unable to Process reason code because
the attached fabric element is not compatible. Set the switch operating mode to McDATA Fabric 1.0 if connected
to an IBM product. Set the switch operating mode to Open Fabric 1.0 if connected to an open-fabric compliant
product manufactured by a different vendor.
4 = Incompatible switch - The switch returned a Process ELP Reject - Invalid Revision Level reason code
because the attached fabric element is not compatible. Set the switch operating mode to McDATA Fabric 1.0 if
connected to an IBM product. Set the switch operating mode to Open Fabric 1.0 if connected to an open-fabric
compliant product manufactured by a different vendor.
5 = Loopback plug connected - A loopback plug is connected to the port with no diagnostic test running.
Remove the loopback plug.
6 = N_Port connection not allowed - The switch is connected to a fabric element through a misconfigured port.
Change the port type to E_Port.
7 = Non-IBM switch at other end - The attached fabric element is not an IBM product. Set the switch operating
mode to Open Fabric 1.0 if connected to an open-fabric compliant product manufactured by a different vendor.
8 = E_Port capability disabled - The product does not have E_Port capability. Enable this functionality through
the appropriate product feature enablement (PFE) key.
A = Unauthorized port binding WWN - The device WWN or nickname used to configure port binding for this
port is not valid. At the Configure Ports dialog box, reconfigure the port with the WWN or nickname authorized for
the attached device, or disable the port binding feature.
