ESX time out with SAN
We have 2 ESX servers connect to Dell SAN, this Dell SAN have been cut to 2 parts: Target 0 and Target 1. Both ESX servers connect to 2 SAN target via Fibre Channel.
Previously only ESX-2 turn off because of no license. We just bought new license for ESX-2. Some how ESX-2 is very slow communicate with SAN, I can not create virtual machine on it, even thought I can create virtual machine on the local disk of ESX-2.
Every time I select any Target on ESX-2, I got errors: "Timed out waiting for server response." and "Object reference not set to an instance of an object.". I wish I can post the picture of it in here, but I could not find any option to post it.
I just have been asked for take care of this problem. I am newbie, I don’t know where to start trouble should on this, can anyone help me out.

Is the SAN set up for single ESX host access?
ASKER
I think the SAN setup for 2 ESX host access. Because someone, who already left the company, set it up. Can you tell me how to find it out?
The reason I said that the SAN setup for 2 ESX host access, because on the VI I saw both ESX server have Target0 and Target1 on the SAN.
The ESX-1 is working fine with these Targets. Only ESX-2, which I just added the new license, have problem.
So, what step should I need to take a look?

How are you managing the ESX servers, direct via the client or thru VirtualCenter?
ASKER
Through VirtualCenter
In VC start a build of a new virtual machine step through until the disk page, it will say what type of access the disk has. Then exit new VM build.
Couldn't find it else where yet.

ASKER
Yes, they all said VMFS. But this is just type of disk format, not thing to do with time out between ESX and SAN.
Something written to the logfiles on the esx server?
check them under /var/log for hints.
