I will be opening a case, but I'm having an extremely annoying issue where the hosts now get stuck int he "Remediating" state despite the upgrade to 5.1 being completed. When this is happening, the host will keep connecting/disconnecting from vCenter until I cancel the remediation manually.. Additionally, this problem persists through even to the following patches that I am installing after the initial update.
Interested to see if anyone else is having this issue.
