Remove a disk from a dynamic disk group

In the process of adding new storage, you may want to rearrange your disks in your existing disk groups. You can remove a dynamic disk from a dynamic disk group if there are no volumes on the disk. If volumes exist, you must delete them before you can remove the disk. Disks shown in Veritas Storage Foundation for Windows to be Unreadable or Foreign can be removed, but doing so causes you to lose all existing data on the disk that is removed from the group. If a disk has failed and is marked as Missing, you can also remove it from the dynamic disk group. However, you cannot remove the last disk from a disk group that is a Microsoft Clustering resource.

To remove a disk from a dynamic disk group, use the Remove Disk from Dynamic Disk Group command. Once you remove all the disks from a dynamic disk group, the disk group is removed from the GUI and the disks become basic disks.

Warning:

Removing a disk that is Unreadable or Foreign from a dynamic disk group changes the disk into a basic disk and all of its data is lost.

To remove a disk from a dynamic disk group

  1. Select the disk of the dynamic disk group and select Remove Disk from Dynamic Disk Group.

  2. Make sure the disk or disks that you want to remove are showing in the right pane of the window.

    Click OK to complete the operation.
