I just deployed the I/O Analyzer 1.5 appliance on a vSphere 4.0 host (ESX, not ESXi) version 4.0.0 build 208167 and created a configuration to test Max Throughput and had it run immediately. I tried this a couple times, rebooting the appliance in between attempts and the tests will not complete. They begin running with a status of "Running (initializing VI SDK)" and then just hang there and never error out or complete. Has anyone seen this behavior before? Any recommendations on how to fix the problem?
I have used the appliance before on a newer vSphere 5.0 test system without issues, this is the first time I have attempted to run it on 4.0, also the previous tests were run using version 1.1 of the appliance.
Thanks,
Brian
