Vmware seeing existing LUNs on a SAN via iSCSI
Here is the situation. I have a client that has a Dell NAS with 2 LUNS created on the NAS. Physical Disk 'A' can see LUN 1 and Physical Disk 'B' can see LUN 2. Both Physical servers are connected to the NAS via iSCSI.
They have recently implemented a VMWare server and we are trying to connect the VMWare server to the NAS via iSCSI. It sees the NAS, but keeps saying "no devices". I have attached a screenshot of the VMware configuration.
What step am I missing?

Yes, I mean Physical server 'A' (Windows 2003 server) can access LUN 1 on the SAN. It can not see LUN2 on the SAN. Physical server 'B' (Windows 2008 server) can access LUN2 but can't see LUN 1 on the SAN.
When you say,
"It's also possible for a VM to have one of these LUNs presented to it by configuring the SAN so that the VMware server has access to it and configuring VMware to pass the LUN to the OS using RDM. Just make sure the physical windows server and VM do not have access at the same time by only having one of them running.".
That's exactly what I am trying to do. Can you point me to more documentation on configuring VMWare to pass the LUN to the OS using RDM?
Thank you.

I didn't think Windows servers and ESXi servers could see the same LUN, but my Dell server person said it's possible. The idea is not to have the Windows server share the LUN with ESXi. ESXi would only access it if the Windows server failed.
