Section 4 Troubleshooting Guide
Each Aurora LS drive canister has 2 LEDs. The top LED flashes Blue and indicates the drive
is functional. The bottom LED shows Red when the drive has been detected as failing to
operate properly. The bad drive will cause the RAID to show a “degraded” status in the GUI
and its location in the RAID will have a Red ‘FAILED’ indication.
4.2
GUI status indicators
The Aurora LS has many background sensory programs that pass data to the GUI and
simplify the ability to check status and determine where problems are. Use of the RAID,
DRIVE, ADAPTER and SENSOR details will give you good indications of how each major
component is working.
4.3
Power System
The power system itself has several components, depending on the type of power system
used. Here are power system components that Rorke has had experience with:
A single ATX-style power supply containing a single fan, non-removable power supply, with no
direct status monitoring. Single power cord.
A single removable power supply system, with a fan at either end of the power supply module,
and a DC power distribution board that the power supply module plugs into, with status
monitoring. Dual power cord.
A dual-redundant power supply system, with a fan at either end of the each power supply
module, and a DC power distribution board that the power supply module plugs into, with
status monitoring. Dual power cord.
While these power system configurations may seem drastically different, there are a large
number of components in them which are common to all three. The motherboard/array
currently does not monitor the output of the power supply status cable – it looks directly at
voltages. Here are some components, along with possible problems/fixes:
Power cord:
The majority of power problems that people have are from things which are
outside of the system. On any power system, if there’s no power going in, it will simply not turn
on. If the cable itself is damaged, it also may not turn on. If the power source is not providing
power (i.e. the wall outlet), it will not turn on, and finally, if either plug on the power cable is
damaged, it may not turn on. One other thing worth mentioning along these lines is electrical
sparks coming out of the power connection on the power supply when it is connected – this is
typically due to a worn-out power cord or damaged receptacle on the power supply. If sparks
or smoke comes out of the power supply itself, it could be a problem with the power supply –
unplug it immediately in either case. On a dual-power supply system, if one power supply isn’t
getting power for whatever reason, it will not register to the array as a power supply failure, as
the power supply actually is working, but is not getting power. Of course, if neither power
supply is getting power, the problem is more likely outside of the array.
