PowerCLI SvMotion a single disk

[Wh33ly]

Hi all,

Most of you know it's possible to storage vMotion a single disk to another datastore through the GUI wizard using the "advanced" option.

We have a few VM's which have disks spread across datastores, now I want to reformat a few LUNs which once were upgraded from VMFS3. Normally I used a simple

get-vm -Datastore <Datastore>  | Move-VM -Datastore <Datastore> -RunAsync -confirm:$false to move all the VM's from one datastore to another.

Problem is that we have a few servers with lots of data which are spread across some LUNs. I'm to lazy to manually "GUI-sVmotion" them to another LUN.I already tried "move-vm" function, neither I and "move-harddisk" function but can't get it to work with a single disk. I think it will be possible but can't see it somehow.

Easiest was something like :

get-datastore <Datastore> | get-harddisk | move-harddisk -datastore <Empty datastore>

Anyone got an idea/tip/script ?

Hi

You can youse Set-HardDisk cmdlets vSphere 5.5 Documentation Center like:

Get-HardDisk -vm <vmname> | where {$_.Name -eq "Hard disk 1"} | % {Set-HardDisk -harddisk $_ -Datastore <Datastore> -Confirm:$false}

Thanks,

I think it could be easier but now got it working with the command below:

Get-HardDisk -vm (get-vm -Datastore "<old_datastore>")  |where {$_.filename -match "<old_datastore>"} | Move-HardDisk -Datastore "<new_datastore>" -RunAsync -confirm:$false
