Temporary ISCSI disk space RRS feed

  • Question

  • I would like to add some iscsi disk space to my dpm server. I have to release this space in a couple of months.

    How can I move the replicas stored on this volume to a different location without interrupting my backups to free up the space.

    Thanks

  • Hi,

    You can use the DPM Powershell command called MigrateDatasourceDataFromDPM.ps1 to move the DPM volumes from one set of disks to another.

    Using MigrateDatasourceDataFromDPM
    http://technet.microsoft.com/en-us/library/dd282970.aspx

    The following commands can be used with the ntdisk number as seen in either the get-DPMDISK output, the Windows Disk Management GUI or DPM Management - Disks GUI.

    EXAMPLE-1 These commands show the migrations going from NTDisk 1 to NTDisks 3, 5, 6. 

    $source = get-dpmdisk -dpmserver DPM-SVR-NAME | where {$_.ntdiskid -eq 1}
    $destination = get-dpmdisk -dpmserver DPM-SVR-NAME | where {3,5,6 -contains $_.ntdiskid}
    MigrateDatasourceDataFromDPM.ps1 -DPMServername DPM-SVR-NAME -source $source -destination $destination

    EXAMPLE-2 These commands show the migrations going from NTDisk 1,2,3 to NTDisks 4,5,6. 

    $source = get-dpmdisk -dpmserver DPM-SVR-NAME | where {1,2,3 -contains $_.ntdiskid}
    $destination = get-dpmdisk -dpmserver DPM-SVR-NAME | where {4,5,6 -contains $_.ntdiskid}
    MigrateDatasourceDataFromDPM.ps1 -DPMServername DPM-SVR-NAME -source $source -destination $destination
