Isilon 10G Network ports not pinging

Question

Hi all, Recently setup a X210 Isilon cluster running v8.1.2.0... I'm having issues with the 10GB ports - the ports are online and are connected to the network switch - we have verified from the Isilon side and from the network side - but i can't ping any of the 10GB interfaces... i've confirmed that the VLAN, subnet, gateway mask, etc are all configured correctly - but i cannot ping the 10G ports in any of the external network pools I provided the MAC address from the Isilon interfaces to our network team and they said that they cannot see the MAC addresses on the switch - which leads me to believe there is a misconfiguration on the Isilon somewhere... What else can i look at here? What am i missing?

@Farhad80 ,

was subnet vlan enabled true or false? and vlan-id set? Sometimes I I have to leave VLAN enabled=false to get ports to work.

philler-2# isi network subnets list -v

Hello Farhad80, Here is a link to How to set up a new Isilon cluster with a 10 GbE external network, I would double check your setup to make sure it done correctly. https://dell.to/3defbRn

@Farhad80  Is Isilon MAC on any switch?

Farhad80 · Answer

Hi @PhilLam ,

Yes i tried setting VLAN enabled to false - that didnt work either

VLAN enabled is set to true and the VLAN ID is also set and matches the VLAN that is on the network switch

It's very odd - when i run isi network interface list i see that the ports are up and are connected but the MAC address is not being advertised on the network switch.

I've also tried rebooting a few of the nodes but haven't had any luck as of yet.

Hi @DELL-Sam L  Thanks for the link - i confirmed that the 10G ports are configured correctly per the document. I have a SR open with support on this also thanks,Farhad

Farhad80 · Answer

@PhilLam  No - none of the Isilon MAC address are being advertised on any of the network switches

Phil.Lam · Answer

@Farhad80, Connect to another 10g switch that you know that works.

Farhad80 · Answer

@PhilLam  The islilon is currently connected to 4 different network switches - all that are actively serving other clients  None of the 10GB ports are working or pinging

Phil.Lam · Answer

@Farhad80, Maybe MTU is wrong? Did it ever work before? If yes then make an SR, if no then you may need Isilon PS. I can't think of anything else.

Phil.Lam · Answer

@Farhad80  Any updates, I'm curious of what was the issue.

PK2chance · Answer

Was this ever resolved . What was the issue.

Farhad80 · Answer

Yes - this was resolved.

The issue was that the ports on the network switch side needed to be hard coded to 10GB instead of auto.

once we made that change the ports came up and everything worked as expected.
