163
Warning The host WWNs (node and port) previously presented by the partner controller module, which is currently
offline, 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 based on its own serial
number for the other controller module.
Recommended actions
• If the controller was replaced or someone reprogrammed its FRU ID data, 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.
Recommended actions
• If this occurs after a firmware update, it indicates that the metadata format changed, which is rare.
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.
Recommended actions
See "Resources for diagnosing and resolving problems" in the SMU help for the System Events panel,
•
or the CLI help for the show events command.
