Hey,
We are also running the Certification process with VMware and our storage array. I'm seeing the exact same error
WARN: Failed Connect to the HOST, Exception: SSH connect Request Failed with RC: 5002
...this is while Workbencg is trying to connect to a DELL 5448 switch.
It's a bummer that VMware decided to pull the plug on the forums/group for VMware Ready TAP partners. Now just trying to find/figure out anything that happens with their Workbench is very time consuming. Of course we can always pay for their support beut even that is long ways...
Let me know what you were able to find out in regards to that SSH error.
