3-65
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).
• 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 appears operational. Exit MAP.
Contact the next level of support. Exit MAP.

A 150 event code indicates a zone merge process 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.
a. At the SANpilot Event Log, examine the first 12 bytes
(0 through 11) of event data.
b. Bytes 0 through 3 specify the E_Port number (00 through 11)
reporting the problem. Bytes 8 through 11 specify the failure
reason as specified in Table 3-13.
