VCS inconsistent for ESX host polling

[fletch2007]

Hi,

the ESX NFS tuning recommendations are working - but only 3 of my 15 ESX hosts are populated in the VSC->Overview pane - the rest show "?Unknown"

Why would that be?

thanks

I opened a case - I'm seeing this in the vsc.log:
Discovery cannot complete, setting overall status to Unknown

thanks
