After reboot a host is not responsive for 20 minutes in vCenter

SanderHogewerf Aug 23, 2019 12:44 AM

Hi folks,

Now a few weeks i have a problem with my vCenter and in particular after rebooting a host.

What happens: After rebooting a host, and it comes back to vCenter it is responsive for about 4 minutes, than the host becomes unresponsive in vCenter.

After about 20-25 minutes the host is resposive again. i can see this because the uptime stops at around 4 minutes and after 20-25 minutes the uptime of the host is adjusted to the right time.

In the time between 4 and 25 minutes i can't do anything with the host out of vCenter.

Does anyone experience the same behavior? Or is there a fix for this?

Kind regards,

Sander

Is this about a particular host, or does it affect all hosts?
In case of a single host, it may be worth disconnecting, and then re-connecting it from/to vCenter to see whether this helps.
If all hosts are affected, then you should search the log files for reasons, or open a support case with VMware for this, because there can be many reasons for this (e.g. networking issues, ...)

Thank you for your answer.

It affects all hosts. I will make a call at Support of VMWare.

Have you gotten anywhere with support on this? I am running the same ESXi build on one of my hosts, and this started happening on this host right after upgrading to 13932383.

Your vCenter server is version Server 6.5 U2e.
Your ESXi version is ESXi 6.5 Update 3.

It is not supported to have the ESXi servers on a newer version than the vCenter Server, the behaviour that you are seeing is typical of such an unsupported configuration. Please upgrade your vCenter server to update 3.

The issue for me appears to be that I used VMware's 6.5 U3 image instead of HPE's. I rolled ESXi back to the previous build and will try it again with the HPE image, which has the correct drivers bundled.

In which case it is still unsupported as per my previous reply. You must upgrade vCenter before the hosts if moving to U3, regardless of whether you use the HPe or the VMware image.

VMWare support gave also this solution. We will update the vCenter. Thanks for your answer!

Hi Cris,

We just updated our vCenter server and still have the problem.

We also updated a host to version 14320405. Which did not do anything, still the problem occurs.

You got any things we could look for?

Do you have any stale paths to storage devices in esx.conf ?
