Recently we started our migration from ESX 3.5 to vSphere. We created a new vCenter Server from scratch and then moved over our 3.5 hosts. I just created a new vSphere 4 host and added it to our vCenter server. Everything seems to be in order with the exception that when I attempt to patch the server using the Update Manager, I get the following error in the tasks when I perform a scan:
Host cannot download files from VMWare vCenter Update Manager patch store. Check the network connectivity and firewall setup, and check esxupdate logs for details.
If I check the vCenter server log, I find the following as the reason (I'm supposing):
2009-09-30 13:46:07.528 02744 warning 'Libs' SSLVerifyCertAgainstSystemStore: The remote host certificate has these problems:
The host certificate chain is not complete.
I cannot seem to find anything useful regarding this error or how to alleviate it. Can anyone shed some light on how to get this working so I can update my host?
Turns out that my problem was DNS. In Update manager under the configuration tab, under Network connectivity and IP address of host name for the patch server, I had the vCenter server entered by name, it wasn't resolving this properly. I selected the IP address of the list and it downloaded correctly. We'll have to correct our DNS server.
