powershell script modification

[td_sk]

Hi Thanks ,

Can some one help to modify the script  .where the script need to execute  the second line if only the HDD2 value exists in CSV file. I tried different option but no luck.

The CSV file is created by an front end web tool and in backend we are using ps script.So some times the user may not required the 2nd HDD in vm.

Sample CSV file

Name	Template	host	datastore	customization	CPU	Memory	hdd1	hdd2	hdd2
VM-Deploy	VMTMPENT2K8	ESXi-host1	VM-DEPLOY-DS	win 2008	4	12	5

Script we are using is

Connect-VIServer localhost

$vms = Import-CSV E:\vm-deploy.csv

foreach($vm in $vms){

   Set-VM $vm.name -NumCpu $vm.CPU -MemoryGB $vm.Memory -Confirm:$false

        New-HardDisk -VM $vm.name -CapacityGB $vm.hdd1 -Datastore $vm.datastore -StorageFormat EagerZeroedThick -Controller "SCSI Controller 1"

            New-HardDisk -VM $vm.name -CapacityGB $vm.hdd2 -Datastore $vm.datastore -StorageFormat EagerZeroedThick -Controller "SCSI Controller 1"

               New-HardDisk -VM $vm.name -CapacityGB $vm.hdd3 -Datastore $vm.datastore -StorageFormat EagerZeroedThick -Controller "SCSI Controller 1"

}

Try something like this

Connect-VIServer localhost

$vms = Import-CSV E:\vm-deploy.csv

foreach($vm in $vms){

   Set-VM $vm.name -NumCpu $vm.CPU -MemoryGB $vm.Memory -Confirm:$false

   New-HardDisk -VM $vm.name -CapacityGB $vm.hdd1 -Datastore $vm.datastore -StorageFormat EagerZeroedThick -Controller "SCSI Controller 1"

  if($vm.hdd2){

     New-HardDisk -VM $vm.name -CapacityGB $vm.hdd2 -Datastore $vm.datastore -StorageFormat EagerZeroedThick -Controller "SCSI Controller 1"

    if($vm.hdd3)

       New-HardDisk -VM $vm.name -CapacityGB $vm.hdd3 -Datastore $vm.datastore -StorageFormat EagerZeroedThick -Controller "SCSI Controller 1"

    }

  }

}

The script will only check for hdd3 when hdd2 is set.
