OS Faults
If you have confirmed that faults are not caused by other factors, diagnose them
as follows:
Fault Symptom
The server is
suspended or
restarted.
Issue 20 (2020-09-25)
Diagnosis Method
Disable C state, P state, T
state, and ASPM in the BIOS
and ensure that the server
functions correctly.
Check whether the Kdump
information contains crashed
process names or board
vendor names. For example,
FC_XX indicates an FC device
breakdown.
Check whether it is a PCIe
card compatibility issue.
● There is a power supply
issue. (A cat err alarm is
generated on iMana 200
or iBMC.)
● The PCIe protocol is not
supported.
● There is a driver issue.
Check whether the
breakdown screenshot
contains CPUidle.
NOTE
The G2500 server does not
currently support this method.
Use the iMana 200 or iBMC
to locate the fault. For
example, determine whether
the alarm was reported for
the DIMM, drive, or
mainboard component.
