96 Event code reference
161 Informational One or more enclosures do not have a valid
path to an EMP. All enclosure EMPs are
disabled.
162 Warning The host WWNs (node and port) previously
presented by this controller module in this
system are unknown. This event has two
possible causes:
• One or both controller modules have
been replaced or moved while the system
was powered off.
• One or both controller modules have had
their flash configuration cleared (this is
where the previously used WWNs are
stored).
The controller module recovers from this
situation by generating a WWN based on
its own serial number.
Verify the WWN information for this
controller module on all hosts that access it.
163 Warning The host WWNs (node and port) previously
presented by an offline controller module in
this system are unknown.
This event has two possible causes:
• The online controller module reporting
the event was replaced or moved while
the system was powered off.
• The online controller module had its flash
configuration (where previously used
WWNs are stored) cleared.
The online controller module recovers from
this situation by generating a WWN for the
other controller module based on its own
serial number.
Verify the WWN information for the other
controller module on all hosts that access it.
166 Warning The RAID metadata level of the two
controllers does not match. Usually, the
controller at the higher firmware level can
read metadata written by a controller at a
lower firmware level. The reverse is typically
not true. Therefore, if the controller at the
higher firmware level failed, the surviving
controller at the lower firmware level cannot
read the metadata on disks that have failed
over.
Update the controller with the lower firmware
level to match the firmware level on the other
controller.
167 Warning A diagnostic test at controller bootup
detected an abnormal operation, which
might require a power cycle to correct.
A service technician must review the error
information returned.
168 C r it i ca l,
warning or
informational
The specified SES alert condition was
detected in the enclosure indicated. Critical
severity is reported if one of the power
supplies in an enclosure has no power
supplied to it or if a hardware failure is
detected.
Most voltage and temperature errors and
warnings relate to the power supply module;
see Table 16. If this is logged as a critical
event and there is no problem with the
power source, the indicated FRU has
probably failed and should be replaced.
