Hi Chandan,

Please run systemctl status NetworkManager

Do the first 3 lines of the output look like this?

systemctl status NetworkManager.service

● NetworkManager.service - Network Manager

    Loaded: loaded (/usr/lib/systemd/system/NetworkManager.service; enabled; vendor preset: enabled)

    Active: active (running) since Wed 2019-06-05 10:49:56 CEST; 2s ago

If so you are running NetworkManager and that is conflicting with the old network service.

NetworkManager is preferred over network service in RHEL 7 and newer.

Regards,

Jan Gerrit

Hi Chandan,

Can you please format the terminal outputs ? It makes them easier to read and increases the chance for you to getting help. :)

Hi Chandas,

Reformating your ip a output shows the lines below:

Hi Jan Gerrit, thanks for having done this ... Chandan, have you seen how the formatted output looks like ? ... :)

Regards,
Christian

Hi Chandas,

Could it be that you have 4 interfaces that have no network cable attached?

Regards,

Jan Gerrit Kootstra

yes. This is physical server. how can i check if cable is attached or not? in ILO, there is no alarm

Hi Chandan,

Just check if the cable(s) is / (are) plugged in or not ... at both ends of course ... :D

Regards,
Christian

Hi Chandas,

Christian means some one has to do a physical check.

Why do you need all 8 NICs to be attached to a network switch?

Regards,

Jan Gerrit

Exactly, Jan Gerrit ... a physical check is what I meant indeed ! :)

Regards,
Christian

for Veritas setup.. 3 NICs will be for heartbeat. Will join this system in veritas cluster

What kind of server is it a blade or a proliant?

its bl460

Guys, Datacentre is in remote location. Is it possible to check this from login in switch?

i found some interconnect error in HP one view. Some downlink port error.
