Examples

Example 1: Modify the size of the replica and recovery point volumes

This example modifies the replica volume size to 5 GB and recovery point volume size to 3 GB.

The first command uses the Get-ProtectionGroup cmdlet to retrieve the protection group object, and stores the result in the $PGroup variable.

The second command uses the Get-Datasource cmdlet to retrieve all data source objects for the protection group stored in $PSGroup, and then stores the objects in the $DSource variable.

The last command uses the Edit-DPMDiskAllocation cmdlet to modify the size of the replica volume and the shadow copy volume for the second data source object stored in the $DSource array.

PS C:\> $PGroup = Get-ProtectionGroup -DPMServerName "Contoso-DPMServer"
PS C:\> $DSource = Get-Datasource -ProtectionGroup $PGroup
PS C:\> Edit-DPMDiskAllocation -Datasource $DSource[1] -ReplicaSize 5368709120 -ShadowCopySize 3221225472
