Event Data: The first byte of event data (byte 0) specifies the port number. The fifth byte (byte 4) states the isolation reason:
1 = Unknown - Isolation reason is unknown, but probably caused by failure of a device attached to the director
through an E_Port connection. Fault isolate the failed device or contact support personnel to report the problem.
2 = Non E_Port mode - Port on this director or other side of ISL is set to F_Port only mode. Change mode of port
to G_Port or E_Port.
3 = Process ELP reject with unable to process reason code - Indicates connection errors with non-IBM
switch. If connected to non-IBM switch, contact the vendor.
4 = Process ELP reject with invalid revision level - Should only happen when connected to non-IBM switch.
Indicates it is not compatible with the revision level in ELP frame. Switches are not compatible.
5 = Loopback indication - Port is connected to another port on the same director or a loopback plug is inserted.
Or two switches have the same WWN. REmove the loopback plug or ISL.
6 = Non-F_Port mode. - Detect that a switch is attached to a port set to F_Port only mode. Change mode of port.
7 = When in legacy mode detect connection over E_Port of a non-IBM switch based on the WWN - If wish
to connect to non-IBM switch, set switch mode to Open Fabric.
8 = E_Port capability disabled and receive ELP - Port configuration issue.
A = Unauthorized port binding WWN - Port binding security authorization on either F_Port or E_Port. Modify
port binding WWN or disable port binding on the port.
B = G_Port ELP timeout - Unresponsive node connected to port. Timed out sending ELP frames and not get
FLOGI or good response to sent ELP. Indicate problem with attached device. Can happen with connection to
either switch or device. Check status of attached device.
C = ESA security mismatch - Processing of the Exchange Security Attribute (ESA) frame detected a security
feature mismatch. The fabric binding and director binding parameters for this director and the attached fabric
element must agree. Ensure the parameters for both fabric elements are compatible or disable the fabric and
director binding features.
D = Fabric binding mismatch - Fabric binding is enabled and an attached fabric element has an incompatible
fabric membership list. Could also be the result of problems delivering EFMD ILS. Update the fabric membership
list for both fabric elements to ensure compatibility or disable the fabric binding feature.
E = Authorization failure reject - The fabric element connected to the director through an ISL detected a
security violation. As a result, the director received a generic reason code and set the port to an invalid
attachment state. Check the port status of the attached fabric element and clean the link's fiber-optic components
(cable and connectors).
F = Unauthorized switch binding WWN - Director binding is enabled and an attached device or fabric element
has an incompatible director membership list. Update the director membership list for the director and the
attached device or fabric element to ensure compatibility or disable the director binding feature.
10 = Authentication failure - Authentication check (CHAP) failed. Update the authentication lists or disable
authentication.
11 = Fabric mode mismatch - Based on the ELP revision level, a connection was not allowed because a IBM
switch in legacy mode is attached to a IBM switch in Open Fabric mode, or a IBM switch in Open Fabric mode is
attached to an OEM switch at an incorrect ELP revision level. Update the fabric mode for one switch.
12 = CNT WAN extension mode mismatch - Based on ELP maximum frame size, assume that connected to a
switch in the CNT WAN extension mode. When in the CNT WAN extension mode, the maximum frame size is
different. Update one of the switches to the correct WAN extension mode.
