Two IP Segments in one VM

[plehry]

This is my first post, although I've been using the communities for quite a while.

Currently, our VM environment contains two hosts and a Dell MD3000i SAN, hooked up to two Gigabit switches that have management pages. Each of the hosts has four NICs, which are also connected to the same Gigabit switches.

I've created a Win2k8 R2 VM with 3 vNICs. The three IP addresses that it has are:

192.168.0.x

192.168.130.x

192.168.131.x

Our SAN has four NICs on it as well and are configured as follows:

192.168.130.x1

192.168.130.x2

192.168.131.x1

192.168.131.x2

There is no problem in getting the VMware iSCSI initiator to connect the hosts to the SAN because I can see the VMFS volumes that I have created on the SAN in vSphere Client and I can also open up the VM consoles, connect to the VMs using RDP, and access network shares.

The problem I have with the above mentioned VM (and any VM I tried this on for that matter) is getting the different IP segments to see each other. For example, in the above VM, if I try to access the management page of the 130.x or 131.x switch through the VM, it doesn't work. If I try to ping the management page for the respective switch, I get a Request Timed Out error message.

I'm stumped on what it could be. I don't believe it's cabling because I can see the VMFS volumes on the SAN in the Storage Configuration section of vSphere Client and I can remote into any of the VMs that are on either host.

Any ideas?

Check Windows Firewall in VM.

Hi Anton.

I did look at the firewall and disabled it completely to see if it would make a difference. No such luck.

Let us know what result you get when :

• disconnect and reconnect your VM vNIC?

• Ping result from pSwitch to VM?

• Add same vNIC to tempVM (sing different IP) and try ping from tempVM to your VM.

vcbMC-1.0.6 Beta

vcbMC-1.0.7 Lite

Thanks AC.

Your tip on pinging from the pSwitch to the VM lead me to try a few other things. When I tried to ping from the pSwitch, there was no response. When I disconnected the VM vNIC, I noticed the wrong VM NIC disconnected, so essentially I had configured the NICs with the wrong set of IP addresses.

I'd swear I configured the switches with the right IP addresses and swapped them around as well to make sure I hadn't configured them wrong and at that time, it didn't work.

Anyway, thanks for your help.
