ESXi 4.0 host (Not Responding) after reboot

[nicholas1982]

Hi, I have a cluster of 3 ESXi 4.0 hosts, I'm using vCenter 4 to manage them.

My issue is when I reboot a host, the status is esx.host.com (Not Responding) for about 20 minutes, however if is restart vCenter service that fixes it straight away.

Anyone else had this issue?

A delay of 10-15 min could be normal.

The status return normal ONLY if you restart VC?

Do you meet minimum requirement for VC Server?

Hi Andre,

I have 2 clusters one with six ESX 3.5 hosts and the other with the three ESXi 4.0 hosts

vCenter is a VM still running on the ESX3.5 cluster (2 vCPUs 3 GB memory)

I have rebooted ESX hosts in the past it never took so long it came back up within 60secs. I have tried rebooting these ESXi 4 hosts several times with the same problem, I never gave it the chance to recover on its own cause I thought it wouldn't so that when I tried restarting the vCenter service to see if that resolved it and it did.

In the last week I have noticed a few issues with vCenter, storage views doesn't work anymore now.. error stating "Storage service in not initilized"

Any idea's?

Name resolution is fine?

All hosts are registered in VC with the FQDN?

Yes name resolution is fine, infact I had a ping on the FQDN during the reboot and after is started getting replies it took a further 15 -20 mins to respond in vCenter

Not other ideas... sorry.

In fact, you should look again to DNS resolution.

I had a situation, when I could ping all the machines (Esx1, Esx2, vCenterServer), but nslookup wan't successful.

When I resolved problem with my DNS (actually a routing problem) only then it was ok.

So - recheck that Esx host and vCenter have ability to nslookup FQDN each other.

I am having a similar issue in my POC environment. The only difference is that my systems (Dell 6850s) take 30+ minutes before coming back online.

I have verified that it isn't a name resolution issue.
