Hello everyone,
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.
My environment:
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.
The problem:
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"
Troubleshooting:
I found the following knowledge base article: http://kb.vmware.com/selfservice/microsites/search.do?cmd=displayKC&docType=kc&externalId=1032444&sl...
- Patches for ESX have been downloaded correctly as I saw in the task list.
- Pinging the vCenter was possible using the IP address, DNS wasn't working at that time due to search domain misconfiguration. I fixed that by entering the correct DNS search domain in the file /etc/resolv.conf
- Disk space should be enough I think:
# df -h
Filesystem Size Used Avail Use% Mounted on
/dev/sda2 4.9G 2.9G 1.7G 63% /
/dev/sda1 99M 32M 63M 34% /boot
none 250M 0 250M 0% /dev/shm
/dev/sda5 2.0G 33M 1.9G 2% /tmp
/dev/sda6 2.0G 208M 1.7G 11% /var/log
- I saw that the update manager was disabled on the host and enabled it:
# esxcfg-firewall -e updateManager
# esxcfg-firewall -q updateManager
Service updateManager is enabled.
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!
