POWERCLI Script Resize VMFS Datastore

[DanielOprea]

Hi,

I have a problem when expanding datastores in 5.0.U1, U2, U3 versions. When large disk cabin, ESXi recognizes the new size, but in "Properties" Datastorage the button "Increase" this is disabled:

I have opened a case with vmware and was told that is a workaround for versions 5.0.X and 5.1.x and  in the 5.5.x version is corrected. He sent me this link: VMware KB:    Cannot grow VMFS datastore, the Increase button is disabled  but I can not apply because it involves service stop.

I found this KB VMware KB:    Growing or expanding a VMFS volume or datastore  and following the steps sometimes allows me to do the expansion, I enable the "Increase", but  many times the button  not working, continues disabled.

I found thisl post "Scripted resize of VMFS datastores" but the script fails me, I can not make it work.

The script is this:

$ds = Get-Datastore -Name "Volume05"
$dsscsi = get-datastore $ds | get-scsilun
$dscanonical = $dsscsi.CanonicalName
$esx = Get-View $ds.ExtensionData.Host[0].Key 
$storSys = Get-View $esx.ConfigManager.StorageSystem 
$dsSys = Get-View $esx.ConfigManager.DatastoreSystem
$vmfsPath = $ds.ExtensionData.Host[0].MountInfo.Path
$storSys.RescanAllHba()
$extent = $dsSys.QueryVmfsDatastoreExpandOptions($ds.ExtensionData.MoRef)
$spec = New-Object VMware.Vim.HostScsiDiskPartition
$spec.diskName = $dscanonical
$spec.partition = "1"
if($extent.Count -ne 0){
  $storsys.ExpandVmfsExtent($vmfspath,$spec)
}

The error I get is:

Excepción al llamar a "ExpandVmfsExtent" con los argumentos "2": "A specified parameter was not correct. 
"
En E:\Resize_VMFS_01.ps1: 15 Carácter: 3
+   $storsys.ExpandVmfsExtent($vmfspath,$spec)
+   ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
    + CategoryInfo          : NotSpecified: (:) [], MethodInvocationException
    + FullyQualifiedErrorId : VimException

Please can someone help me?

Did you already check the vpx logs on the vCenter ?

There is sometimes more information about the error available in there.

Hi LucD,

The issue seems to be the diskName property, that should hold only 1 canonicalname.

Try changing

$dscanonical = $dsscsi.CanonicalName

into

$dscanonical = $dsscsi.CanonicalName | Select -First 1

Hi LucD,

The error now is this:

It looks as if more than 1 object is returned for the Get-Datastore.

Try like this perhaps

$ds = Get-Datastore -Name "Volume05" | Select -First 1

$dsscsi = Get-ScsiLun -Datastore $ds | Select -First 1 

$dscanonical = $dsscsi.CanonicalName 

$esx = Get-View $ds.ExtensionData.Host[0].Key  

$storSys = Get-View $esx.ConfigManager.StorageSystem  

$dsSys = Get-View $esx.ConfigManager.DatastoreSystem 

$vmfsPath = $ds.ExtensionData.Host[0].MountInfo.Path 

$storSys.RescanAllHba() 

$extent = $dsSys.QueryVmfsDatastoreExpandOptions($ds.ExtensionData.MoRef) 

$spec = New-Object VMware.Vim.HostScsiDiskPartition 

$spec.diskName = $dscanonical 

$spec.partition = "1" 

if($extent.Count -ne 0){ 

   $storsys.ExpandVmfsExtent($vmfspath,$spec) 

}

Hi LucD,

I tested the script, is giving error, gives another error:

In the powegui i see this error:

But this is not right. Is free space on the disk.

Just got this working in 5.5. I think the issue is that you're using the wrong function for your intended purpose (should perhaps be using ExpandVmfsDatastore instead of ExpandVmfsExtent).

# The start of a datastore name. E.g., if you have multiple datastores:
# ds1, ds2, ds3
# and want to expand all of them, put 'ds' here.
$dsPrefix = 'dsprefix'

connect-viserver vcenter
Write-Host
$rds = get-datastore | ? { $_.Name -match "^$($dsPrefix).*$" } | sort-object
if ($rds.Count -ge 0) {
    $vmhost = get-vmhost -id $rds[0].ExtensionData.Host[0].Key
    $vmhostView = get-view $vmhost
    $dsSys = get-view $vmhostView.ConfigManager.DatastoreSystem
    $rds | % {
        $ds = $_
        $expandOpts = $dsSys.QueryVmfsDatastoreExpandOptions($ds.ExtensionData.MoRef)
        if (($expandOpts.Count -gt 0) -and ($expandOpts[0].Spec.GetType().Name -eq "VmfsDatastoreExpandSpec")) {
            $userResponse = Read-Host -Prompt "Expand VMFS datastore '$($ds.Name)' [Y/N] (default 'Y')?"
            if ((-not $userResponse) -or ($userResponse -eq '') -or ($userResponse -ieq 'y')) {
                Write-Host "Expanding VMFS datastore '$($ds.Name)'"
                $dsSys.ExpandVmfsDatastore($ds.Id, $expandOpts[0].Spec)
            }
        }
    }
}
else {
    Write-Host "No datastores found."
}
