esx4 and iscsi san

[snootalope]

can someone please set me straight here... I'm doing some testing and got a text esx4 box hooked up to an iscsi san. I booted a test vm on the box and booted the test vm, which of course is kept on the san. once they're all booted I unplugged the nic that hooks up to the san. I figured the VM itself would freeze up since it can't access the san anymore, but it doesn't. Why is that? if the entire vm is on the san, shouldn't it go down when it can't access the san anymore?

My end goal here is to have a failover between nics for the san, but this was just a first test to see what exactly happened to the VM. I'm positive the nics aren't failing over yet as I can't vmkping the san target when I unplug the cable. Why is that the vm stays active if it can't access the san?

As long as the VM isn't trying to actually read/write to the disk it should stay up since everything is in memory. Once it tries to access the page file, or open My Computer it'll probably blow up, unless vSphere has the disk info cached in memory.
