I’m finally back from a whirlwind week at VMworld! What an incredible adventure - full of fun, new friends, also eye-opening bits of feedback in terms of what we’re doing with OpsCheck and the vWire project. Regarding OpsCheck, (besides the typical “Cool, I’ll check it out”) there were two comments at the booth that really stood out:
1. “I don’t have any problems with VMotion so why should I use OpsCheck?”
2. “I tried OpsCheck and was shocked to find I had a couple of things misconfigured.”
Both comments speak to the same thing: overconfidence! But, couple statement #1 with statement #2, and the need for something like OpsCheck really stands out, especially since VMotion is so critical to virtual environments.
Therefore, I challenge those who are confident about their VMotion configurations to test out OpsCheck anyway. OpsCheck takes just a short while to run. As one person joked at our booth… “he likes to move it move it… he likes to move it move it.” And if you like to move it, better make sure you actually can. : )

Believe it or not, I ran into a situation over the weekend in production where VMotion was working, however, it was taking an EXTREMELY long time (20+ minutes for a VM with 4GB vRAM). After some quick digging, I found out the pNIC on the source ESX host had reverted from its orginally negotiated speed of 1000Mbps (1Gbps) to 100Mbps. The problem lies somewhere between the pNIC and the switch port. The network guys assure me the switch port is configured for 1Gbps. Bad cable is a long shot but I won’t rule that out either.
The point of my story is that I could have used a product like OpsCheck to let me know I had a poorly configured pNIC attached to the VMKernel switch that handles VMotion. I don’t want to wait until a maintenance window where time is short to find this out. I would have liked to have been notified the moment that pNIC changed speeds from 1000Mbps to 100Mbps. Who knows when it happened - a day ago. A week ago. A month ago.
