90 Event code reference
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 ri t i c al,
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.
169 Informational The specified SES alert condition has been
cleared in the enclosure indicated.
This event is generated when the problem
that caused event 168 is cleared.
170 Informational The last rescan indicates that the specified
enclosure was added to the system.
171 Informational The last rescan indicates that the specified
enclosure was removed from the system.
172 Warning The specified vdisk has been quarantined
because not all of its disks are available.
There are not enough disks to be fault
tolerant. The partial vdisk will be held in
quarantine until it becomes fault tolerant.
• Ensure that all disks are latched into their
slots and have power.
• During quarantine, the vdisk is not visible
to the host. If after latching disks into their
slot and powering up the vdisk, the vdisk
is still quarantined, you can manually
remove the vdisk from quarantine so that
the host can see the vdisk. The vdisk is
still critical.
When the vdisk has been removed from
quarantine, event 173 is logged.
