I have a vmware 4.1 managed by vsphere 4.1 several of my host's show disconnected when trying to reconnect I get a specified host not responding. I removed one from inventory but no luck adding that host back. Each of the host's can be managed by the vsphere client software just fine so I am assuming that it is a vcenter issue any help would be appreciated.
Thanks
Chris

Sorry should have included that the management service had been restarted on all machines so no joy on that avenue.

Check you have no storage issues, no iSCSI or FC LUNs added or removed, this can cause Host issues.

Missing datastores.

The host that I slicked does not show correct storage but the other two which I am trying to reconnect have identical storage/networking showing in the local host each is currently running vm's which are operating correctly.

no path or storage changes on storage network, and no one has issued a Rescan Storage or Refresh datastores

No storage changes but I have probably run a rescan storage since this began.

It's possible this issue is caused by storage changes, we can cause the issue you our experiencing.

One other piece of information I can add when trying to reconnect to the host's it gives me the same error if I use an incorrect password, like it's not even getting to the authenication point

Yes, Host is broke, we've seen this alot, and VMware still seem to have not fixed this issue, if storage changes, and cause the host to become non-reponsive.

Reboot host, raise Support Request with VMware Support, and request a fix.

You are not the only site that has experienced this issue, it it is storage related.

No update or patch that we are aware of.
