Thank you for the post. I put one of my hosts back on build 3l a second time so that I could work with VMware on a solution. The experience the second time was different than the first. During the first upgrade, VMs were unreachable on the upgraded host. After the second upgrade, my dedicated vmotion nic couldn't communicate with the other host (we moved the vmotion service to a working nic and VMs were usable on the upgraded host). After hours of troubleshooting with VMware network support, I was told to work with my internal network team as everything appeared correct on the VMware side of things. I was calling it a day when I saw your post. Today I reverted my upgraded host, upgraded it to 3m, and everything worked as expected. I migrated all of my VMs to the upgraded host and updated the other host to 3m and rebalanced the load. All good now.
