Event Codes
Table 32: 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 the event data for the reason.
Action: Action depends on the reason specified in the event data.
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–Isolation reason is unknown, but probably caused by failure of a
device attached to the switch through an E_Port connection. 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.
If the established switches are already operating in McDATA Fabric 1.0 (also
known as Homogeneous mode when managing the SAN using HAFM), set the
switch operating mode to that mode. Otherwise, set the switch operating mode to
Open Fabric 1.0 if connected to M-Series Fabric Directors or Edge Switches in
Open Fabric 1.0 mode, or 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. If the established switches are already operating in
McDATA Fabric 1.0 (also known as Homogeneous mode when managing the SAN
using HAFM), set the switch operating mode to that mode. Otherwise, set the switch
operating mode to Open Fabric 1.0 if connected to M-Series Fabric directors or
edge switches in Open Fabric 1.0 mode, or 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 port configured as an F_Port. Change the port type to E_Port.
7 = Non-HP M-series switch at other end–The attached fabric element is not an HP
M-series switch. Set the switch operating mode to Open Fabric 1.0 if connected to
an Open Fabric-compliant product manufactured by a different vendor.
A = Unauthorized port binding WWN–The device WWN or nickname used to
configure port binding for this port is not valid. Reconfigure the port with the WWN
or nickname authorized for the attached device.
