vCenter Server 5 added Hosts after short time "not responding" state

[STRI]

Hi

I made a test setup with ESX5 an vCenter Server 5 Appliance.

I was able to add host, but after a short time (some minutes) all host become the status "not responding".

restart management agents fix it for a short time only.

connecting the hosts directly with vSphere Client works fine.

any suggestion?

kind regards

Using HP-branded installation by chance?

This happen when there is a firewall between host and vCenter, with the following ports not opened.

ESXi 5.x

902

TCP/UDP

ESXi 5.x

vCenter Server

(UDP) Status update (heartbeat) connection from ESXi to vCenter Server

Also refer the below link for the port requirement.

I had same when i was implementing vSphere 4 and it got resolved once the port is opened between vcenter server and the host,

Yes, HP branded ESXi 5.0 install iso!?

[STRI]

No, no Firewall between vCenter Server Appliance and ESXi Host!?

There's a bug in HP's ESXi5 ISO, see here: http://h10025.www1.hp.com/ewfrf/wc/document?cc=us&lc=en&dlc=en&tmp_geoLoc=true&docname=c03007056

YOu need to uninstall HP's preloaded license.

Can you confirm that the vCenter Server appliance as well as the hosts resolve correctly with DNS? Did you create Hast-A entries for them? If you don't have a DNS server you'll have to configure the hosts files on each of them.

DNS Records exits!

-> It seems to be the HP iso bug like Ollfried wrote.

Thanks anyway and kind regards!
