Hello,

I had a ESX host lose connection on network and my VMs that were on the ESX host failed over to another ESX host. now I see all VMs on this ESX host, however what is the step-by-step instructions to properly migrate back to original host? I want to make sure I do correcly.

Thanks,

If you have VMotion, simply right-click on the VMs in question, select Migrate. In the wizard that displays, select to Chang Host only and select the host it should be on. If you don't have VMotion, you can still migrate, but cold migrate. Power down the VM and follow the same step as above. It takes about 3-6 secs per VM.

I forgot to mention - if you have to do cold migration, once done with the migration, you power back on the VM. :)

If you have HA that failed them over then as coolsport00 indicates use vmotion to move the vms amongst hosts. If you have HA then you have vmotion.

Actually...HA doesn't require VMotion, but DRS does. :)

Yes, but the minimum licensing level that gives you HA also gives you vmotion :)

Ok I get it. Migrating back to another host I can do it with VM powered on, however migrating to a differant datastore, I must be licensed to do while VM is on, otherwise I need to power it off.

I just tested and migrated back to original host while VM was on, however I noticed I couldn't (grayed out) migrate to a differant datastore.

Is that correct?

Thanks,

That is correct - you must have a minimum of Enterprise licensing to do Storage vMotion (which is what migrating to different datastore is).

GREAT!!!! I'm getting it. The light bulb came on....dim, but it's coming on. ;-)

You know I started this project two weeks ago and after about a million comments, I'm getting it a bit a lot more. I couldn't have done it without everyones help from EE.

Thanks,
