Just a heads up for those who had issues when upgrading their Dell servers to 6.7U3. The original issue turned out to be the Dell OpenManage module: https://kb.vmware.com/s/article/74696
I noticed this week that my vCenter Update Manager snagged OpenManage 9.3.1. I used a host we keep around for testing and deployed it and so far it is not showing any issues.
Additional article (they haven’t updated it yet that 9.3.1 is released): https://www.dell.com/support/article/ch/fr/chbsdt1/sln318662/omsa-hosts-with-esxi-6-7-update-3-become-unresponsive-to-vcenter-with-task-time-outs-if-omsa-9-3-0-installed?lang=en
