Event codes 140 and 142 occur only if the optional OpenTrunking
feature is enabled.
•
Event code 140 - OpenTrunking firmware detected an ISL with
Fibre Channel traffic that exceeds the configured congestion
threshold.
•
Event code 142 - OpenTrunking firmware detected an ISL with
no transmission BB_Credit for a period of time that exceeded the
configured low BB_Credit threshold. This results in downstream
fabric congestion.
No action is required for an isolated event or if the reporting ISL
approaches 100% throughput. If the event persists, perform one of
the following:
•
Relieve the congestion by adding parallel ISLs between the
fabric elements reporting the problem.
•
Increase the ISL link speed between the fabric elements
reporting the problem (from 1 Gbps to 2 or 4 Gbps).
•
Reroute Fibre Channel traffic by moving device connections to a
less-congested region of the fabric.
Was the maintenance action successful?

The fabric, ISL, and product are operational. Exit MAP.
Contact the next level of support. Exit MAP.

Event code 150 indicates a fabric merge process failed during ISL
initialization. An incompatible zone set was detected or a problem
occurred during delivery of a zone merge frame. This event code
always precedes event code 070, and represents the reply of an
adjacent fabric element in response to a zone merge frame. Obtain
supplementary event data as follows:
a. At the Event Log, examine the first 12 bytes (0 through 11) of
event data.
b. Bytes 0 specifies the E_Port reporting the problem. Bytes 8
through 11 specify the failure reason as listed in
