I have one NSX Controller (out of 3) that reports an error "Controller not available for this operation" when trying to "fetch disk alerts". This is accessed from "networking and security" -> "installation" -> "management" tab, select controller node under "NSX Controller nodes" -> "Actions" -> "fetch disk alerts"
The other nodes report the "disk latency alerts" metrics when this action is performed on them.
Would anyone have suggestions how to further troubleshoot this issue or insight as to what might be the cause?
There are otherwise no errors or alerts or indications that anything is wrong.
nsx controller version 6.3.7073587
nsx manager version 6.3.5.7119875
vcenter 6.5
Thank you
