I got an issue with updating ESX 3.5 hosts - the problem is that vCenter Update Manager seems not to be able to check the ESX hosts for installed updates.
I'm using vCenter Server 4.1.0 (Build 258902, German-000) to manage two ESXi 4.1 and one ESX 3.5 cluster(s). The ESX 3.5 cluster includes 4 hosts with ESX 3.5.0 (Build 283373).
For deploying updates I'm using Update Manager 4.1 which works fine for my two ESXi 4.1 clusters.
It's not possible to update/check the hosts of the ESX 3.5 cluster. VMware Update Manager is configured to download patches for ESX 3.5 - the repository is configured and Update Manager also downloaded patches for ESX 3.5. If I try to validate the compliance of a single host (or the whole cluster) I'll get the following error message:
"Checking (HOSTNAME) for updates not possible"
"Status: Unknown error"
I found the following knowledge base article: http://kb.vmware.com/selfservice/microsites/search.do?cmd=displayKC&docType=kc&externalId=1032444&sl...
Checking the host is still not possible - do I have to reboot the ESX host because of the modification of resolv.conf?
Does anybody have a tip for me? I couldn't find a solution for my problem using the search.
Thanks a lot in advance!
