online. This MAP describes fault isolation for problems that may
occur during the POST/IPL process.
If an error is detected, the POST/IPL process continues in an attempt
to initialize the switch and bring it online. But an event code 400
displays when the switch completes the POST/IPL process.
1
Was an event code 400 or 411 observed at the Event Log (EFC
Server) or at the SANpilot event log?
YES NO
↓
Analysis for the failure is not described in this MAP. Go to
MAP 0000: Start MAP on page 195.
2
The following table lists event codes, brief explanations of the codes,
and the associated steps that describe fault isolation procedures.
3
POST/IPL diagnostics detected a CTP card failure as indicated by an
event code 400 with supplementary bytes of event data.
• Byte 0 is a FRU code (02) that indicates a failed CTP card.
• Byte 1 is the slot number (00) for the CTP card.
Because the CTP card is not a FRU, replace the switch.
4
POST/IPL diagnostics detected a firmware failure (as indicated by
event code 411) and performed an online dump. All Fibre Channel
ports reset after the failure and attached devices momentarily logout,
login, and resume operation.
Perform the data collection procedure and return the CD to IBM for
analysis.
