Moving subdisks

The purpose of moving a subdisk is discussed in another section.

Note:

You are not allowed to move a subdisk that is part of a boot or system volume.

Storage Foundation for Windows automatically checks the state of the data before beginning the subdisk move. If the data is degraded, the subdisk can still be moved. After moving, you need to reactivate the disk to clear the Degraded state.

Moving a subdisk from one disk to another involves a certain amount of time. The SmartMove feature can help reduce the time for this operation.

Note:

Dynamic disks belonging to a Microsoft Disk Management Disk Group do not support the Move Subdisk command.

To move a subdisk

  1. In the tree view, select the volume that contains the subdisk you want to move.
  2. Identify the subdisk that you want to move, and display it in the right pane of the VEA console.

    If you are concerned about load balancing, look for a disk with High or Critical I/O activity. It has a yellow or red pie symbol in the cell to the right of its name in the Statistics tabular view. You may also be aware that a disk has had difficulties because of minor disk errors that have occurred. Such a disk may display an Online (Errors) state from time to time.

    To display the subdisk in the right pane, click on its volume in the tree view, and then click on the Subdisks tab in the right pane. You can use the subdisks'Properties command to further identify the characteristics of a volume's subdisks.

  3. Right-click the subdisk you want to move to bring up its context menu.
  4. Select Move Subdisk from the context menu.

    The Move Subdisk window appears.

    Choose either automatic or manual selection of the destination disk or disks for the subdisk to be moved to.

    If you want to select the destination disk(s), click Manually assign destination disks. In the left panel of the window, highlight the disk(s) you want to assign as the destination disk or disks and use the Add or Add All button to move the disk(s) to the right pane of the window.

    You may also check Disable Track Alignment to disable track alignment on the destination disks.

  5. Click OK when you are satisfied with the changes.
