Data Source Migration to Custom Volumes

  • Artigo

There may be scenarios where we would want to have some data sources’ data from DPM storage pool to some specific custom volumes. This post is here to show the main steps:

Run the dpm2010-ldmstat.ps1 script to see which data sources have the most extents. This only runs on DPM 2010:

==============================

LDM&ShrinkStats

==============================

Total extents : 20

Total data sources : 15

Total volumes : 18

Get the list of custom volumes we can migrate to and label the volumes accordingly:

The migratedatasourcedatafromdpm.ps1 expects the replica volume to be the first array member, and the recovery point volume to be the second.

PS C:\Program Files\Microsoft DPM\DPM\bin> Get-DPMVolume mjlc-dpm01

VolumeLabel VolumeSize DiskName

----------- ---------- --------

replica-1 15728640000

diffarea-1 47185920000

PS C:\Program Files\Microsoft DPM\DPM\bin> $dpmvol = Get-DPMVolume mjlc-dpm01

PS C:\Program Files\Microsoft DPM\DPM\bin> $array = @($dpmvol[0],$dpmvol[1])

PS C:\Program Files\Microsoft DPM\DPM\bin> $array

VolumeLabel VolumeSize DiskName

----------- ---------- --------

replica-1 15728640000

diffarea-1 47185920000

Now run the migratedatasourcedatafromdpm.ps1 and provide source and destination using the following syntax:

PS C:\Program Files\Microsoft DPM\DPM\bin> migratedatasourcedatafromdpm -dpmservername mjlc-dpm01 -source $ds[5] -destination $array = @($dpmvol[0],$dpmvol[1]) FormatVolumes 1-true/0-false : 0

Have Fun!!
