Controller failure in a single-controller configuration
Cache memory is flushed to CompactFlash in the case of a controller failure or power loss. During the write
to CompactFlash process, only the components needed to write the cache to the CompactFlash are
powered by the super-capacitor. This process typically takes 60 seconds per 1 Gbyte of cache. After the
cache is copied to CompactFlash, the remaining power left in the super-capacitor is used to refresh the
cache memory. While the cache is being maintained by the super-capacitor, the Cache Status LED flashes
at a rate of 1/10 second off and 9/10 second on.
IMPORTANT:
configurations, there is no need to transport a failed controller's cache to a replacement controller because
the cache is duplicated between the peer controllers.
Transportable cache only applies to single-controller configurations. In dual controller
Actions
No action required.
•
Verify that the power cord is properly connected and
check the power source it is connected to.
•
Check that the power supply FRU is firmly locked into
position.
•
Check the event log for specific information regarding
the fault.
•
Isolate the fault.
•
Contact an authorized service provider for assistance.
Actions
No action required.
When isolating faults in the power supply, remember that
the fans in both modules receive power through a
common bus on the midplane, so if a power supply unit
fails, the fans continue to operate normally.
•
Check that the power supply FRU is firmly locked into
position.
•
Check that the power cable is connected to a power
