Dmotion timeout

I'm planning to use Dmotion to migrate a fairly large guest (around 200GB). I just wanted to see if anyone has come across issues with the operation in VC timing out for larger guests. I seem to remember timeout values with Vmotion so I assume this could be an issue with Dmotion also.

Thanks.

With gigbit connectivity - you should be fine...

I would want to keep the I/O down to a minimum during a DMotion. DMotion gets it unoffical name from the "delta" files created on the ESX 3.x.x hosts VMFS 3 volume (where you moving the VMDK files too). Plenty of people here have reported problems if the deltas in snapshots grow beyond 2GB. So you want to do it as quick as possible - to keep the delta as slim as possible...

ps there's nothing more reliable - than a power off and cold clone to the VMFS3 volume. Make sure you have an effective VM backup in place before trying any cold-migrate or DMotion...
