SAN32M1 Fabric Switch Installation and Service Manual
22
As indicated by an event code 072, a switch E_Port is connected to
an unsupported switch or fabric element.
Advise the customer of the problem and disconnect the interswitch
link to the unsupported switch. Exit MAP.
23
A 140 event code occurs only if the optional OpenTrunking feature is
enabled. The event code indicates OpenTrunking firmware detected
an ISL with Fibre Channel traffic that exceeds the configured
congestion threshold.
No action is required for an isolated event. However, if this event
persists, perform one of the following:
•
Relieve the congestion by adding parallel ISLs between the
switches reporting the problem.
•
Increase the ISL link speed between the switches reporting the
problem (from 1 Gbps to 2 Gbps).
•
Reroute Fibre Channel traffic by moving device connections to a
less-congested region of the fabric.
Did the corrective action solve the problem and relieve the reported
ISL congestion?
NO
YES
↓
The ISL appears operational. Exit MAP.
Contact the next level of support. Exit MAP.
24
A 142 event code occurs only if the optional OpenTrunking feature is
enabled. The event code indicates 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. However, if this event persists, perform
one of the following:
•
Relieve the congestion by adding parallel ISLs between the
switches reporting the problem.
•
Increase the ISL link speed between the switches reporting the
problem (from 1 Gbps to 2 Gbps).
