Extend existing disk conditionally and add if no disk

[gajuambi]

Here is what i am trying to achieve.

1. increase the disk space of a particular disk (C & D drive) if they are less than a particular company standard value
2. detect whether there is a 2nd disk or not and if not then add a 3rd disk

optionally:

a)extend the increased disk from inside the guest OS

b)initialize, format the newly added disk from inside the guest OS

currently this is what i came up with

#if the harddisk 1 is less than 60 increase the hard disk size to 60 and then extend it from inside the guest OS or else skip this action

Get-HardDisk -vm TestVM | where {$_.Name -eq "hard disk 1"} | if ((Measure-Object -Property CapacityGB -Sum) -lt 60) {

Set-HardDisk -CapacityGB 60 -ResizeGuestPartition -Confirm:$false

}

else

{

Write-Host "No action is needed" -foregroundcolor Red

}

Now I do not know how to add a 2nd disk of 80GB after checking whether it has a 2nd disk or not.

My motto behind this is, it should check whether there is a 2nd disk or not and if there is then skip adding the disk and if there is no 2nd disk (hard disk 2) then add an 80GB hard disk.

You could do something along these lines

$hd = Get-HardDisk -vm TestVM

if($hd.Count -eq 1){

    New-HardDisk -CapacityGB 60 -VM TestVM

}

else{

    Write-Host "2nd HD present - No action is needed" -foregroundcolor Red

}

if($hd[0].CapacityGB -lt 60){

    $hd[0] | Set-HardDisk -CapacityGB 60 -ResizeGuestPartition -Confirm:$false

}

else{

    Write-Host "HD1 is 60GB or more - No action is needed" -foregroundcolor Red

}
