I have restarted the host completely I have even shut it down and let it sit for a few hours before powering it back on. I have also pulled it from the cluster and added it back in. Once i boot it back up it show no error for a few hours and then i get the same warning again.
Yes it is part of a DRS cluster. It is set to Fully Automated and as Aggressive as it gets. I have turned DRS off and still get the same issue.
It will go away if i clear the error or restart the services or the host. But it will pop back up again after a couple of hours.
The odd part is in the Hardware Status in VCenter shows Memory Alert. But nothing on the DIMM's or the system board. Then you log into the Cisco UCS Manager shows no issues or ever has.
