150 Director 2/140 Service Manual

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 directors or
switches reporting the problem.
■
Increase the ISL link speed between the directors or 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 low
BB_Credit condition?
NO YES
↓
The ISL is operational. Exit MAP.
Contact the next level of support. Exit MAP.

A 150 event code indicates a zone merge failed during ISL initialization. Either an
incompatible zone set was detected or a problem occurred during delivery of a
zone merge frame. This event code always precedes a 070 event code, and
represents the reply of an adjacent fabric element in response to a zone merge
frame.
Obtain supplementary event data for each 150 event code.
1. At the Hardware View, choose Logs > Event Log. The Event Log displays.
2. Examine the first 12 bytes (0 through 11) of event data.
3. Bytes 0 through 3 specify the E_Port number (00 through 23) reporting the
problem. Bytes 8 through 11 specify the failure reason ( Table 19 ).
