Table 27. Event descriptions and recommended actions (continued)
Number Severity Description/Recommended actions
● The current controller that logged this event probably has down-level firmware. Update
the firmware in the down-level controller. Both controllers should have the same firmware
versions.
When the problem is resolved, event 20 is logged.
90 Info. The partner controller does not have a mirrored configuration image for the current controller,
so the current controller's local flash configuration is being used.
This event is expected if the other controller is new or its configuration has been changed.
Recommended actions:
● No action is required.
91 Error In a testing environment, the diagnostic that checks hardware reset signals between controllers
in Active-Active mode failed.
Recommended actions:
● Perform failure analysis.
95 Error Both controllers in an Active-Active configuration have the same serial number. Non-unique
serial numbers can cause system problems. For example, WWNs are determined by serial
number.
Recommended actions:
● Remove one of the controller modules and insert a replacement, then return the removed
module to be reprogrammed.
96 Info. Pending configuration changes that take effect at startup were ignored because customer data
might be present in cache.
Recommended actions:
● If the requested configuration changes did not occur, make the changes again and then use a
user-interface command to shut down the Storage Controller and then restart it.
103 Info. The name has been changed for the indicated volume.
Recommended actions:
● No action is required.
104 Info. The size has been changed for the indicated volume.
Recommended actions:
● No action is required.
105 Info. The default LUN (logical unit number) has been changed for the indicated volume.
Recommended actions:
● No action is required.
106 Info. The indicated volume has been added to the indicated pool.
Recommended actions:
● No action is required.
107 Error A serious error has been detected by the controller. In a single-controller configuration, the
controller will restart automatically. In an Active-Active configuration, the partner controller will
kill the controller that experienced the error.
Recommended actions:
● Download the debug logs from your storage system and contact technical support. A service
technician can use the debug logs to determine the problem.
108 Info. The indicated volume has been deleted from the indicated pool.
