Critical Warning parameters
Parameter
Description
Bit
critical warning
Critical warning, such as
overtemperature and
insufficient redundant space.
l
0
: No warning.
l
1
: The available spare
space has fallen below
the threshold.
l
2
: The temperature is
above an over
temperature threshold or
below an under
temperature threshold.
l
3
: The NVM subsystem
reliability has been
degraded due to
significant media related
errors or any internal
error that degrades NVM
subsystem reliability.
l
4
: The media has been
placed in read only
mode.
l
5
: The volatile memory
backup device has failed.
Typical fault causes are as follows:
l
Available spare space below the threshold: Causes include excessive number of damaged
blocks.
l
Temperature above the overtemperature threshold or below the undertemperature
threshold: Causes include disk temperature below 0°C or above 78°C.
l
NVM subsystem reliability degraded due to internal errors: Causes include excessive
number of failed disk granules or internal subsystem operating exceptions.
l
Media placed in read only mode: Causes include capacitor failures.
l
Volatile memory backup device failure: Causes include capacitor voltage below 28 V or
above 35 V.
----End
Fault Diagnosis Instance
The available space is smaller than the threshold.
Step 1
Check whether the value of
available spare
in the SMART information exceeds 10%, if the
value is greater than or equal to 10%, stop using the disk and back up data immediately.
Otherwise, go to
