I was wondering if someone could help me. Recently, our vCenter server when belly up, and we were forced to migrate to a new vCenter server. Our engineer took the opportunity to connect all 5 of our vCenter servers with SSO. After a successful migration i began trying to re-add these hosts to the new vcenter. When i go to Virtualization and look at the cluster, it shows the hosts as italicized, and it has orphaned all the existing "nodes" that had been entered from our prior vcenter. I ended up losing all my historical data after "re-adding" them to the new vcenter, which irked me but that isn't even the worst of my problems. Over the last week, at least once a day, one of my hosts suddenly starts alarming about memory, and when i look in Manage Nodes the vendor no longer shows VMware and suddenly it no longer knows that it is an ESX host. If i look at the Node Details Machine Type is now "Unknown". When i go into Edit Properties, I notice that Poll for VMWare check box is selected but it no longer says:
"Polling for this ESX Host is handled by vCenter using existing credentials."
I'm forced to readd the host, losing historical data once again.
This is what i have tried:
1. Rediscover the node - it ends up showing as vmware once again, but is not showing under any vcenter server in the Virtualization page. I do not lose data.
2. Poll Now - polls the node, but does not pull asset inventory again. Still shows as "not being monitored" in Virtualization.
3. Re-Add the node - Lost all historical data, but its under the vcenter again, until it decides to happen again.
Notes of environment:
NPM version 11.0.1
vSphere 5.5 Update 1
hi had, the same thing, try removing the v center server wait about 30 minutes, then re add it
