Fault

Symptom

Diagnosis Procedure

Quick Recovery Method

A packet

error or

packet

loss

occurs on

a network

port.

1. Use the

Computing Product

Compatibility Checker

check whether the NIC type is

compatible with the server

board. Use

Computing

Product Firmware and Driver

Mapping Checker

to check

whether the NIC firmware and

driver versions match the OS.

If they do not match, upgrade

the NIC firmware and driver

first.

2. Check whether there are an

increasing number of network

port packet losses and errors.

If there is no continuous

increase, ignore this error.

3. Insert the NIC that you suspect

to be faulty into another slot,

and insert a normal NIC into

the slot that you suspect to be

faulty. Then, check which of

these is causing the fault.

4. Connect the suspicious

network cable to a normal

server, connect a normal

network cable to the

suspicious server, and check

whether the fault is caused by

the suspicious network cable.

5. Switch the service traffic from

the network port that you

suspect to be faulty to a

different network port. Then,

check whether the fault is

caused by the network port.

6. To check parameters regarding

the packet error or loss, run

the ethtool -S eth

command

in Linux (or similar in other

operating systems).

7. Collect OS logs. For details, see

4.2 Collecting OS Logs

1. Check whether the packet

loss occurs only on a single

server. Run the ethtool -S

eth

command to check

the packet loss type and run

the top command to check

the system resource usage

(software interrupts, CPU

usage, and memory usage)

and NIC traffic.

2. When you have the

customer's permission to

interrupt services, connect a

PC to the port and check for

packet loss. Connect the PC

to other working ports, and

check optical modules,

optical cables, and uplink

switches. Then, replace or

adjust components based

on the actual situation.

3. If the NIC is causing the

fault, restart the server

when interruption will not

affect services, and check

whether the communication

is normal. If the fault

persists, power the server

off and on. If the fault still

persists, replace the NIC.
