Appendix E Event Codes 287
163 Warning The host FC World Wide Names
(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 drives 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.
