How can I move the VMDK from LUN to another LUN ?

Hi Experts.

How can I move the VMDK from LUN to another LUN ?

There are 2 LUN in my storage (Fujitsu DX90)
Both LUN's capacity is around 650Gbyte.

One LUN capacity is runing out of space.
Therefore I want to move fileserver from LUN to another LUN.

In this case, How can I move the VMDK from LUN to another LUN ?

It is better to use Backup software ?
VMware converter ?

Well, before you can move the .vmdk file...or if it's a whole VM, you will need to power it down because it will be in use.

Veeam FastSCP is what I recommend: (free tool). First, let me say, if you wanna move the whole VM...and have VMotion capability, just do that. If you don't have VMotion, yes, you can do a V2V of the VM using vCenter Converter or vCenter Converter Standalone tool ( If this is a standalone host, use FastSCP. Power down the VM, install FastSCP on local workstation, add the host/hosts, browse the file directory, then copy/past the VM folder, or individual file/s you need to the other datastore location.

Hope that helps.

How do you backup your VMs at present?

Is this just a single ESX server?

You could download a trial of vSphere vCenter, and use the MIgrate Function. (whilst the VM iks powered off).

VMware Converter is one option. Using converter, you only have to select the Virtual Disk you want to move/convert to another datastore.

Also, something else you could do is, with the VM powered down, go into the datastore the VM is on. Rt-click on the VM folder, or click the VM folder & rt-click the individual VM file you want to move, and select 'Move to'. Click YES at the prompt. A 'Move Items To' dialog box displays with a list of datastores. Select the datastore you want to move the VM or individual VM file to, then click the 'Move' button.

Thank you for your comments.I apprreciate everyone's answer.

I forgot to remark my environment.
There are two storage servers and each storage server has a LUN . Therefore total number of LUN is 2.
These storage servers connect to 2SAN switch.
There are 2 ESXi server connecting 2SAN switch.
I am using VMware vSphere ver.4.0 Advance . That is why vMotion strorage is not available.

Do the VMware Converter option, it is probably simpler for you. (and you will have a rollback plan, if it goes wrong), as the original virtual disk would not have moved.
Are you wanting to move just the disk or the whole VM? Since you have vCenter..prob just easiest to use Converter.
yes vmware convertor is a copy not a move in a v2v
Are you able to shutodwn the vm to perform the move? If you can afford downtime, I would suggest the easiest option to be to migrate the vm via vcenter.
Since you do not have storage vmotion, you can essentially shutdown the vm and then right click to migrate the vm. you will get the option to change datastore.
Within advanced settings, you will get the option to change location for a single disk or entire vm.

Thank you for your comments.

vCenter is also running as a virtual machine.
Is it possible to move vCenter from LUN1 to LUN2?


What kind of advantage are there if  I move a single disk, not entire vm?
From a maintenance point of view, Does it seem to be complicated ?

Thanks in advance.

Are you licensed for Storage vMotion, otherwise you will need to power down the VM.

Moving a single disk, will be quicker, than the entire VM.
If wanting to move vCenter, without storage vmotion, you need to pwr it down which means your choices using vCenter features are mitigated. You would then need to use any of the aformentioned methods. If you move single file, assuming it's just the vmdk, it's somewhat quicker. The files outside the vmdk are quite small size-wise so it would only be a min or 2 quicker.  If you have many vmdks, then it would obviously be many mins/hrs quicker than moving whole vm.
Complicated?..not at all. Just a simple copy/paste. You can then reattach the vmdk/virtual disk to the vm once it's moved & be back up & running.
