Import a dynamic disk group

Perform the following steps to import a disk group.

Note:

Normally, you cannot import a dynamic disk group on a computer without having deported it on the computer where the disk group was located previously. However, the Import Dynamic Disk Group command has an option to clear the host ID of the previous computer, so that you can do an import operation. This option should be used with caution.

Note:

While importing a cluster disk group as a cluster-shared disk group (CSDG), you must select the "Clear Host ID" check box.

Note:

After upgrading the disk group to the latest version and importing a disk group as a cluster-shared disk group (CSDG), you need to manually create the Volume Manager Shared Volume resource for each volume in a disk group. To do this,

Note:

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

Once you have deported a dynamic disk group and disconnected the disks from the original machine, do the following to import the dynamic disk group

To import a dynamic disk group:

  1. Reinstall the hardware in the destination computer.
  2. If the disks are hot swappable, open the VEA console on the destination computer and issue a Rescan command. If the system had to be shut down to install the disks, it will have done a rescan automatically during the restart.

    Once the rescan completes or the system restarts, the dynamic disk group and disks should be listed; but the dynamic disk group is in a Deported state, and the disks are in the Offline or Foreign state.

    Occasionally, you may have to rescan a second time to get the disks showing as Offline or Foreign, particularly if you do the first rescan very quickly after installing the disks on the second computer system.

  3. Right-click on a disk name in the dynamic disk group or the dynamic disk group name in the tree view, and select Import Dynamic Disk Group from the menu that appears.
  4. If you want to change the dynamic disk group's name, type in a new name for the group in the screen that comes up.

    Note:

    The dynamic disk group name is limited to 18 ASCII characters. It cannot contain spaces, slash mark (/), backslash (\), exclamation point (!), angle brackets (< >), or equal sign (=). Also, a period cannot be the first character in the name.

    If the disk group you import has a name longer than 18 characters (as was possible in earlier versions of Volume Manager for Windows), you may be asked to shorten the disk group name. It is possible that you will be asked to shorten the name to fewer than 18 characters if the disk group's volumes also have very long names.

    Do not rename a dynamic disk group that contains a system or boot volume, otherwise an error can occur.

    On this screen, you may also check Clear host ID to clear the host id of the previous computer that had the dynamic disk group.

    This screen also lets you import the dynamic disk group as a cluster disk group. Select Import as cluster disk group to import the dynamic disk group as a cluster disk group. Importing the dynamic disk group to a cluster disk group requires that the dynamic disk group be connected to a shared bus.

    The Import as cluster disk group option is already selected if you import a cluster disk group. Select Import as dynamic disk group to import the cluster disk group as a dynamic disk group.

    In addition, you can specify that the dynamic disk group be imported as a SAN disk group. This option is already selected if you import a SAN disk group. Select Import as SAN disk group to import the dynamic disk group as a SAN disk group.

  5. If you have not done a deport command on the computer where the disk group was located previously, click the check box to clear the host ID of the other computer.
  6. Click OK to import the dynamic disk group.

    If the volumes in the dynamic disk group come up as Failed or Degraded, you need to repair the volumes.
