Warning: two or more network adapters are in the same subnetwork: Anything wrong??

[tingshen]

any idea what's the purpose of that warning message?

If I require 4-8 Ethernet ports for iSCSI teaming purpose, would there be any problem? Why can't I have more than 1 NIC port appear in the same subnetwork?

Hi!

You shouldn´t have two NICs in the same subnet.

Your configuration could be:

NIC1 IP 192.168.188.1/24
NIC2 IP 192.168.189.1/24

and add both to a bonding IP e.g.

192.168.190.1/24

with "balance-rr".

Thanks DerFux.

What if I only have 2 iSCSI SAN router and require more than 1 NIC connecting to each routher for bonding IP purpose?

Sorry if the question sounded silly....I just started configuring iSCSI SAN....

Hi!

I don´t know if I understand your question or configuration completely.

If you have 2 iSCSI switches and want to connect 2 bonded NICs to each switch your configuration could be

NIC1 IP 192.168.1.1/24
NIC2 IP 192.168.2.1/24

and the bonded IP to the first switch e.g.

192.168.10.1/24

with "balance-rr"

plus

NIC3 IP 192.168.3.1/24
NIC4 IP 192.168.4.1/24

and the bonded IP to the first switch e.g.

192.168.20.1/24

with "balance-rr".

The important part is that each "physical" IP plus each bonded IP are in a separate network.

Hi!

Sorry, copy and paste.

It has to be:

plus

NIC3 IP 192.168.3.1/24
NIC4 IP 192.168.4.1/24

and the bonded IP to the SECOND switch e.g.

192.168.20.1/24

How do I team up the NICs if both are on diff subnet? Which subnet should my ESXi server be in order to connect to DSSV6? All my SAN configurations are on separated but common/shared iSCSI subnet. DSSV6 is diff?

You need to update your build as 3530 is very OLD!!! Use the latest build 5626 and you wont see this message.
