I'm the only one with this issue? After upgrade of my ESXi host to 5.1 the OnTap Simulator 8.1.1 no longer work. I only get the follwoing error:

 

Cannot open the disk '/vmfs/volumes/<id>/vsim-DOT811-7m/DataONTAP-sim.vmdk' or one of the snapshot disks it depends on.

The system cannot find the file specified

VMware ESX cannot find the virtual disk "/vmfs/volumes/<id>/vsim-DOT811-7m/DataONTAP-sim.vmdk". Verify the path is valid and try again.

 

Before the Update everything worked without any issue. The vmdk Files are there, it also not works if i manually assign those disk files. I have also never made any snapshots, this cannot be the problem.

A re-download of the Simulator files and add to the Host, get the same issue.

Everyone I have the fix. It's a VMWare issue. By default ESXi 5.1 does not load the the vmkernel multiextent module. See the KB Below.

The Fix: all you have to do is ssh into your host and  run this command from the cli: 

# vmkload_mod multiextent

The other stuff in this article didn't apply to me. All I had to do was run this command and my ONTAP Sims booted like usual, no issues. Unfortunately after a ESXi host reboot the multiextent module unloads and you have to perform this again to get your Sims to boot. If anyone can find a way to make this persistent with a switch or write a script that makes it load upon host reboot. I'm sure everyone would be very thankful.
