Number Severity Description/Recommended actions
606 Error A controller contains unwritten cache data for a volume, and its supercapacitor has failed to
charge.
Due to the supercapacitor failure, if the controller loses power, it will not have backup power to
flush the unwritten data from cache to CompactFlash.
Recommended actions:
● Verify that the cache-write policy is write-through for all volumes.
● Contact technical support for information about replacing the controller module.
607 Warning The local controller is rebooting the other controller.
Recommended actions:
● No action is required.
608 Error A back-end cabling error was detected.
Recommended actions:
● If the message says both controllers are connected with a undefined error type, one of the
cables is incorrectly connected to a controller egress port forming a loop in the SAS
topology. Check back-end cabling from each controller egress port to determine the
incorrect connection.
● If the message says controller egress ports are connected to each other, one of the cables is
incorrectly connected to a controller egress port forming a loop in the SAS topology. Check
back-end cabling and make sure that SAS cables are connected to the correct ports for the
port specified.
●
If the message says an EBOD loop has been created, one of the cables is incorrectly
connected to an expansion enclosure egress port forming a loop in the SAS topology. Check
back-end cabling and make sure that SAS cables are connected to the correct ports for the
port specified.
● If the message says a cable is connected to the middle port but that port is not supported,
check back-end cabling and make sure that SAS cables are connected to the correct ports
for the port specified. Move the cable from the middle port of the IOM to the left or right
port, as appropriate.
609 Error An alert condition was detected on a door lock element. The door lock element reports status
associated with the enclosure drawer. The drawer has been reporting as open for a long period
of time. This may reduce cooling, potentially causing the enclosure to overheat.

When the problem is resolved, an event with the same code will be logged with Resolved
severity.
