Bring a foreign disk back to an online state

To bring a foreign disk back to an online state depends on the original context of the disk.

Note:

Because a volume can span more than one disk (such as with a mirrored or RAID-5 volume), it is important that you first verify your disk configurations and then move all the disks that are part of the volume. If you do not move all the disks, the volume has a Degraded or a Failed error condition.

The following describe the various contexts:

Note:

Microsoft Disk Management Disk Groups do not support the Import Dynamic Disk Group command.

To add a foreign disk that was created on another computer

  1. Right-click on the disk and select Import Dynamic Disk Group.

    A dialog box comes up that displays the name of the dynamic disk group.

  2. Indicate the name for the dynamic disk group as follows:

    • If you want to leave the name as is, click OK.

    • If you want a new name for the dynamic disk group, type a new name for the group in the New name entry box and then click OK.

  3. If you import a dynamic disk group from a different system, then click the check box to clear the host ID of the other system.

    The disk group then imports. All existing volumes on the disk are visible and accessible.

    More information on importing and deporting dynamic disk groups is available.

    • Use Import Dynamic Disk Group if the Foreign disk has a secondary dynamic disk group (that is, a dynamic disk group other than the dynamic disk group containing the computer's boot or system disk) and you have switched between operating systems on a dual-boot computer.

      When you have one or more secondary dynamic disk groups on a disk in a dual-boot environment, the disk is marked as Foreign when you switch between operating systems, because the secondary disk groups are not automatically imported. A shared primary dynamic disk group on a disk in that situation is automatically imported.

    • Use Merge Foreign Disk if the disk was originally created on the current computer but was removed and now you have reattached it to the current computer and want to restore it to its status as a member its original dynamic disk group.
