ESXi 5.1 Fibre Channel VMs not recovering from disconnect.

I've recently built a free version 5.1 ESXi server connected to an Openfiler 2.99 Fibre Channel SAN.  I remember (Openfiler 2.3 and ESXi 4.1), I used to be able to unplug the fibre cable or server power and reconnect and the guest would resume where it left off.  Now, when I try this, the VM never recovers and has to be reset.  (which fixes it).  Now, the VM guest files are located on a physical disk on the Host and the vmdk is located on the external OF fibre channel.  My questions are:

Do all the files need be located on the fibre channel in order to recover the guest vm?

Is this a new timeout feature on esxi 5.1 and is there a way to increase it?

Is there a way to 'jolt' the unresponsive vm to continue once the LUN is represented?

Thanks,
Chris

When you state "recover the guest", guest would resume?

Guest can only resume, if they are paused, if you remove the storage from a host running VMs, the VMs will fail!

iSCSI and FC do have timeout values in advanced options.

But I've never known VMs to continue if the storage is missing!

I swear on my soul.  

ESXi 4.1 and Openfiler 2.3, unplug the cable, rip the power out of the back of the SAN, reconnect and present the LUNs, and wallah, the mouse would unfreeze and the guest would be completely responsive.  I will look into the FC timeouts and test tonight with all the VM files and VMDKs centrally located on the FC.

Thanks for your input!

OK, by increasing the timeout, I was able to re-create, but only if the just the VMDK is located on a remote device.  In esxi 5.1, it's known as APD.
