Detailed Description

The Set-DatasourceDiskAllocation cmdlet modifies disk allocation for the protected data.

Using the -Manual parameter you can specify the amount of disk space to allot to each data source in a protection group.

Using the -CustomRequirements parameter you can specify the volumes to use for each data source in a protection group.

If you use neither parameter, DPM will assign the default disk space and volumes for the data source.

Parameters

-AutoGrow

Indicates whether the replica or recovery point volume size should be increased automatically when the user space threshold is exceeded.

Attributes

Name	Value
Required?	true
Accept wildcard characters?	false
Accept Pipeline Input?	true (ByValue)
Position?	1

-ProtectionGroup

The name of a protection group.

Attributes

Name	Value
Required?	true
Accept wildcard characters?	false
Accept Pipeline Input?	true (ByValue)
Position?	0

-DestinationDiskPool

Specifies the set of disks on which DPM will allocate volumes for migration of a data source. This parameter is migration specific.

Attributes

Name	Value
Required?	true
Accept wildcard characters?	false
Accept Pipeline Input?	false
Position?	3

-DestinationReplicaVolume

Specifies the destination volume allocated by the user for migrating replicas of a data source. This parameter is migration specific.

Attributes

Position?	3

-MigrateDatasourceDataFromDPM

Indicates migration of the data source from the current volumes to a new set of volumes.

Attributes

Name	Value
Required?	true
Accept wildcard characters?	false
Accept Pipeline Input?	false
Position?	2

Position?	4

-CustomRequirements

Allows you to specify replica and shadow copy volumes manually.

-CommonParameter

This cmdlet supports the common parameters: Verbose, Debug, ErrorAction, ErrorVariable, WarningAction, WarningVariable, OutBuffer, and OutVariable. For more information, see about_CommonParameters.

Input and Return Types

The input type is the type of the objects that you can pipe to the cmdlet. The return type is the type of the objects that the cmdlet emits.

Notes

Examples

EXAMPLE 1

 
          $pg = Get-ProtectionGroup -DPMServerName "TestingServer" 
          $mpg = Get-ModifiableProtectionGroup $pg 
          $ds = Get-Datasource -ProtectionGroup $mpg 
          Get-DatasourceDiskAllocation -Datasource $ds[1] 
          Set-DatasourceDiskAllocation -Datasource $ds[1] -ProtectionGroup $mpg 
          Set-ProtectionGroup $mpg

This command sets the disk allocation the second data source in the data source list $ds.
