Set-Datastore -Name not working

[mk_ultra]

What should be a simple one liner is driving me insane.

I am trying to rename a datastore on a new host via PowerCLI.

$IPAddress = [host IP address]

$HostName = [host name]

$ESXiHost = Get-VMHost $IPAddress

$DefaultDatastoreName = ($ESXiHost | Get-Datastore | where {$_.capacityGB -like "*95*"}).Name

$NewOSDatastoreName = $HostName+"_os"

$ESXIHost | Get-Datastore -Name $DefaultDatastoreName | Set-Datastore -Name $NewOSDatastoreName -Confirm:$False

I have confirmed each of these individual variables yields the correct object/string. I have tried eliminating variables by feeding in explicit strings.

No matter what I do, whenever I run the final line, it just returns the current datastore name:

Name FreeSpaceGB CapacityGB
---- ----------- ----------
temp_name 93.844 95.250

Please help!

Are you connected to a vCenter or an ESXi node?
If that datastore is managed by a vCenter, you can't do the rename when connected to the ESXi node.
You have to be connected to the vCenter

I just tested that, and I see the same behavior you are seeing.
The Set-Datastore cmdlet might return some more info on the why.

From the ESXi Host Client you'll notice that the Rename Action is greyed out.

Perfect! Thank you!
