Diagnostic tools

Several diagnostic tools provide feedback about problems with arrays.
Description
Auxiliary Power LED. This LED glows steadily when 3.3V
auxiliary voltage is detected. The auxiliary voltage is used
to preserve BBWC data and is available any time that the
system power cords are connected to a power supply.
Battery Health LED. To interpret the illumination patterns of
this LED, see the following table.
BBWC Status LED. To interpret the illumination patterns of
this LED, see the following table.
LED4 pattern Interpretation
One blink every The system is powered down, and the cache contains data that has
two seconds not yet been written to the drives. Restore system power as soon as
possible to prevent data loss.
Data preservation time is extended any time that 3.3 V auxiliary
power is available, as indicated by LED 2. In the absence of
auxiliary power, battery power alone preserves the data. A fully-
charged battery can normally preserve data for at least two days.
The battery lifetime also depends on the cache module size. For
further information, refer to the controller QuickSpecs on the HP
website (http://www.hp.com).
Double blink, The cache microcontroller is waiting for the host controller to
then pause communicate.
One blink per The battery pack is below the minimum charge level and is being
second charged. Features that require a battery (such as write cache,
capacity expansion, stripe size migration, and RAID migration) are
temporarily unavailable until charging is complete. The recharge
process takes between 15 minutes and two hours, depending on the
initial capacity of the battery.
Steady glow The battery pack is fully charged, and posted write data is stored in
the cache.
Off The battery pack is fully charged, and there is no posted write data
in the cache.
One blink per An alternating green and amber blink pattern indicates that the
second cache microcontroller is executing from within its boot loader and
receiving new flash code from the host controller.
— There is a short circuit across the battery terminals or within the
battery pack. BBWC features are disabled until the battery pack is
replaced. The life expectancy of a battery pack is typically more
than three years.
— There is an open circuit across the battery terminals or within the
battery pack. BBWC features are disabled until the battery pack is
replaced. The life expectancy of a battery pack is typically more
than three years.
