[<CommonParameters>] Description
The Set-DPMDatasourceDiskAllocation cmdlet changes disk allocation for protected data. By default, System Center - Data Protection Manager (DPM) allocates disk space and volumes for the data source. The cmdlet gives you the following options for changing disk allocation:
- Specify the amount of disk space to allocate to each data source in a protection group.
- Specify the custom replica and shadow copy volumes to use for each data source in a protection group.
- Specify the target volume for each data source in a protection group which uses volume-based storage.
- Specify destination disk or custom volumes for migration of data.
Examples
1: Migrate a datasource from one volume to another
PS C:\>$pg = Get-DPMProtectionGroup
PS C:\>$mpg = Get-DPMModifiableProtectionGroup $pg[0]
PS C:\>$ds = Get-DPMDatasource $mpg
PS C:\>$vols = Get-DPMDiskStorage -Volumes
PS C:\>Set-DPMDatasourceDiskAllocation -ProtectionGroup $mpg -Datasource $ds[0] -TargetStorage $vols[0] -MigrateDatasourceDataFromDPM
PS C:\>Set-ProtectionGroup $mpgMigrating a datasource involves modifying the PG the datasource is in. The first command gets the protection group object from DPM. The second command converts it into a modifiable protection group, $mpg. The third command gets the datasources that are a part of the modifiable protection group. Next, $vols stores all the available volumes. If $ds[0] needs to migrated to $vols[0], the next command instructs DPM to modify the PG to change the volume allocated to the datasource The last command then saves all the above actions performed on the Protection Group.

-Datasource
Specifies a data source object for which this cmdlet modifies disk allocation. A data source can be a file system share or volume for the Windows operating system, Microsoft SQL Server database, Microsoft Exchange Server storage group, Microsoft SharePoint farm, Microsoft Virtual Machine, DPM database, or system state that is a member of a protection group.
| Type: | Datasource |

| Position: | 4 |
| Default value: | None |
| Required: | True |
| Accept pipeline input: | False |
| Accept wildcard characters: | False |

| Default value: | None |
| Required: | True |
| Accept pipeline input: | False |
| Accept wildcard characters: | False |
-DestinationShadowCopyVolume
Specifies the destination volume that the user allocates to migrate shadow copies of a data source. This parameter is migration specific.

| Default value: | None |
| Required: | True |
| Accept pipeline input: | False |
| Accept wildcard characters: | False |
