Probable Cause Indicates that the current chassisConfig option is not supported by the firmware on the standby
control processor (CP). This is true even if the standby comes up and appears to be operational.
High availability (HA) synchronization of the CPs will not be allowed.
Recommended Either change the chassisConfig option to 1 with the chassisConfig command, or upgrade the
Action firmware on the standby to the version running on the active CP.
Severity WARNING
EM-1028
Message
<timestamp>, [EM-1028], <sequence-number>, FFDC, WARNING, <system-name>, HIL
Error: <function> failed to access history log for FRU: <FRU Id> (rc=<return
code>).
Probable Cause Indicates a problem accessing the data on the world wide name (WWN) card field-replaceable unit
(FRU) or the WWN card storage area on the main logic board.
The problems were encountered when the software attempted to write to the history log storage to
record an event for the specified FRU. The return code is for internal use only. This can indicate a
significant hardware problem.
The FRU ID value is composed of a FRU type string and an optional number to identify the unit, slot,
or port.
Recommended If the message persists, reboot or power cycle the switch.
Action
If the message still persists, replace the WWN card, or the switch (for nonbladed switches).
Severity WARNING
EM-1029
Message
<timestamp>, [EM-1029], <sequence-number>,, WARNING, <system-name>, <FRU Id>, a
problem occurred accessing a device on the I2C bus (<error code>). Operational
status (<state of the FRU when the error occurred>) not changed, access is being
retried.
Probable Cause Indicates that the I2C bus had problems and a timeout occurred.
Recommended This is often a transient error.
Action
Watch for the EM-1048 message, which indicates that the problem has been resolved.
If the error persists, check for loose or dirty connections. Remove all dust and debris prior to
reseating the field-replaceable unit (FRU). If it continues to fail, replace the FRU.
Severity WARNING
