ESXi 4.1 U2 hosts disconnected

[kopper27]

hi guys

I previously had all my 12 ESXi hosts version 4.0 and I updated to ESXi 4.1 Update 2 from scratch complete new installation.

Now my hosts are continuosly being disconnected it happends like every 8 days. Like every 8 days one host gets disconnected and there is no way to get the host back I have to manually reboot the hosts.

I had vCenter 4.1 update 1 and I just upgrade to vCenter 4.1 update 2

Any idea why these continuos disconnected status?

logs from last time

Alarm 'Host connection failure': an SNMP trap for entity ---------- was sent info 27/05/2012 05:48:51 p.m.

Alarm 'Host connection lost' on ------------------ cannot  send email to error 27/05/2012 05:48:51 p.m.

thanks a lot

I've checked that before....the hosts were OK but I just added the vCenter IP since it was empty

1. Administration > vCenter Server Settings.
2. Click Runtime Settings.

and after that I reconfigured HA

but the way is there any recent updates or patches after ESXi 4.1 update 2?

No idea about latest patch..

Anyhow ...disconnect host vpxa logs gives any useful info other than mention above?

[kopper27]

no I think I have to configure the logs since I understand when the host is rebooted ( I had to reboot the last time) logs are gone....

So I am thinking to configuring this logs

thanks
