Vmotion times out at 90%

[KNardi]

ESX v 3.0.2, VC 2..0.2

Whenever I try to migrate (vmotion) a server to my new server, it goes 90% in and hangs for a while then times out.

ANy help is appreciated

Hi,

sounds like a network issue on your vmkernel which is used by the vmotion.

When it times out it should give you an error. What does it give you?

All I get is "Operation Timed out"

For this particular cluster, 3 ESX servers are 3.0.1 and the new one is 3.0.2, is that ok or do they all have to be the exact version?

You can try this for more information:

Log into each the source and destination servers

tail -f /var/log/vmkernel

start your Vmotion as it is running the logs are going to start generating in the vmkernel file, when it fails see if you can see the reason...

Sidenote, are you using NAS/NFS for your backend storage? If so, do you have both servers either using IP or FQDN to access it? If one is using IP and the other is using FQDN that might cause it to fail.

Is your vmotion network (vmkernel) running at 100mb/s or 1GB?

What apps are running on the server you are trying to vmotion? SQL? Exchange?

VMotion will usually time out at 90% if it cannot do the final move of the running memory state etc of the VM due to traffic on the vmkernel network.
