ESXi 4 host not responding, sort of hung, VM down
Posted on 2011-05-01
I had a ESXi 4 host server that had problems today. It only had one VM on it and the call started with the VM going offline. I could connect to the ESXi host through the vSphere client but I could not reset or power off the VM or look at the console, nothing showed up in the ESX event log and the server never rebooted or anything.
I tried putting the host in maintenance mode and I got a error that it timed out, I tried updating it through the host update tool and it timed out, I connected to the ILO and tried to look at the console and it started to let me connect, I hit F2, it asked me to change the admin password and I was able to put the old and both new in and then it just sort of hung and I hit enter but it never did anything and just sat at the change password screen.
I ended up just rebooting the server through the ILO and now the host and VM are up.
I tried to look at the logs and they only go back about 15 minutes ago and have no previous events.
This is a weird problem and I was hoping you guys could give me advice on how to handle this if it were on a major host server, if this thing had 50 production hosts rebooting would not be an option unless all of the host just went down. At any rate what could I have checked before rebooting the host and does anyone have any ideas what would cause this to happen?
The one VM is a SMS server. The host is up to date other than 2 patches that I am applying right now.now.
EDIT: Also need to add the ESXi host is running the basic free version and it is not connected to a vCenter server, yaay cheapo's in management.
