In vSphere 6.7U1 I could not update my ESXi-Hosts in my cluster because the new Remediation Pre-Check fails with the following error: “DRS should be enabled”
It also has a big red banner:
“Pre-check found problems that will block remediation. See details below. The blocking problems may have caused the pre-check to complete prematurely. Therefore, after fixing the problems, please re-run this pre-check.”
So Host remediation is blocked with error message: “Pre-check has found 2 issues that will block remediation”
Here are my work arrounds so far that I also posted on the relevant spiceworks thread:
1: use the old flex/flash-client. There is no pre-check
2: remove the esxi server from the cluster (just drag&drop the the server in question from the cluster to the datacenter). Outside of the cluster there is no DRS, so the pre-check works and update is not blocked anymore
But I think the second is the easiest way to do it.
I also opened a support request with VMware. I will keep you updated.
