Troubleshooting
Controller
Problems with the controller fall into two categories, serious and disastrous. The controller is the
only major component in the K-Series RAID system that can cause a fatal failure on its own.
After the system ÒPower On Self TestÓ (POST) is complete, the controller will begin initializing the
RAID. The following message will be displayed by the LCD panel:
If everything is working normally, shortly after this message, the system should be up and running.
The LCD display panel will display the Ready screen.
Problems at Startup
Controller failure at startup will most likely result in a failure to initialize the RAID. If your
system hangs at this point of the power-up (wait at least 5 minutes before deciding that the system is
stuck), power off, wait 10 seconds, and try again.
Attempt this remedy three times, if the system still does not initialize, check all other components
for good connections and status as indicated by LEDs.
Other Problems
The controller is the heart and brain of a RAID array. If during normal operations the controller
fails, the most obvious symptoms will be that the LCD does not light and the array is inaccessible.
Note
: Once the POST and RAID initialization are completed (meaning that the controller is
functioning properly), any subsequent failures or problems will most likely generate an event
message in the array event log.
Enclosure
The enclosure elements (power supplies, fans, drive trays, LED indicators, ports) are, in most
cases, monitored by the terminal utility via the systemÕs RS-232C interface.
Power Supplies
The system comes with two, hot-swappable, redundant power supplies, each of which can supply
sufficient power for the entire array indefinitely.
If a power supply fails, a variety of things will happen. The event will be recorded in the array
event log by the controller. At the same time, the system alarm will sound and the Attention LED
