Hi!

I'm a newbie in Virtualization and now i'm trying to set-up a new server.

I have some physical servers (PCs) and 2 LPARs with 2 VLAN interfaces on p510Q Machine.

I have configured VIO server 1:1 as it was described in IBM article "How to work with VLANs using the IBM Virtual I/O Server".

Problem is that everyting is working exept LPAR's communication. LPARs ping s VIO, HMC & other physical machines in the same VLAN, but do not ping and see each other.

One LPAR have 2 virtual network interfaces (vlan 2 & 3), other have only one (vlan 2)

This is what i have (exactly):

VIO:
ent0 (Physical adapter connected to the switch)
ent2 (PVID=100, Trunk=yes, 802.1Q=yes, VLANs: 2,3) - for SEA
ent3 (PVID=2, Trunk=no, 802.1Q=no) - for remote administration

LPAR1:
Virtual adapter 1 (PVID=2)
Virtual adapter 2 (PVID=3)

LPAR2:
Vritual adapter (PVID=2)

-----------

On VIO i've done the following:
mkvdev -sea ent0 -vadapter ent2 -default ent2 -defaultid=101
mkvdev -vlan ent4 -tagid 2
mkvdev -vlan ent4 -tagid 3

mktcpip -hostname vio1 -inetaddr 172.16.250.1 -interface en3 -netmask 255.255.0.0

On LPARs (I'm using SuSE):
lpar1:
eth0: 172.16.250.3/255.255.0.0
eth1: 172.30.0.1/255.255.0.0

lpar2:
eth0: 172.16.250.4/255.255.0.0

Also i have some physical machines from both subnets (172.16 & 172.30).

Everybody are able to see & ping each other: VIO pings LPARs, my workstation pings vio, lpar1, lpar2; lpar pings vio & my workstation etc.

BUT! They do not ping each other.

I have no idea where i was wrong...

Have you checked if you have enabled interpartion communication (can be enabled from HMC) ..?

I've located the problem, it was because of a mistake in routing table of LPAR1, thanks for being involved.
