VMWare ESXi Host Disconnects from Vcenter
Posted on 2014-02-10
My organization is having an intermittent problem with our ESXi 5.0 servers. Last week we witnessed our three ESXi hosts not respond and then disconnect from vcenter. After going through the KB article from VMWare on what to do, we could only complete a hard restart of the servers (we know now the best practice at all).
Today, I witnessed another server reach the not responding state and then disconnect from vcenter. We never had a purple screen on the console. This time, I was not able to F12 into the screen and attempt to issue a restart command. Last time I was able to; however, it just hung for almost and hour and we were required to do a hard restart.
I was hoping someone could give me suggestions as to where I should look for problems or has anyone had this problem/encountered this problem? It's quite frustrating because I'm basically always anticipating some type of severe issue every couple of days. Also, every time this happened, I've still been able to access the servers running- i.e. Exchange.
Thanks in advance,
