Creating a dynamic disk group

Create a cluster disk group and volumes on only one node of a cluster. The volumes can be accessed by other nodes in the cluster by first deporting the cluster disk group from the current node and then importing it on the desired node.

Note:

Setting up the cluster creates physical disk resources for all the basic disks on the shared bus. To use those disks for the SFW cluster disk groups, you must remove the physical disk resources from the cluster. Otherwise, a reservation conflict occurs.

Note:

Dynamic disks belonging to a Microsoft Disk Management Disk Group do not support cluster disk groups.

Follow the steps in this section to create one or more disk groups for your application.

To create a dynamic disk group

  1. Open the VEA console by clicking Start > All Programs > Veritas > Veritas Storage Foundation > Veritas Enterprise Administrator (or launch the VEA from the Solutions Configuration Center) or, on Windows 2012 operating systems, from the Apps menu, and select a profile if prompted.
  2. Click Connect to a Host or Domain.
  3. In the Connect dialog box, select the host name from the pull-down menu and click Connect.

    To connect to the local system, select localhost. Provide the user name, password, and domain if prompted.

  4. To start the New Dynamic Disk Group wizard, expand the tree view under the host node, right click the Disk Groups icon, and select New Dynamic Disk Group from the context menu.
  5. In the Welcome screen of the New Dynamic Disk Group wizard, click Next.
  6. Provide information about the cluster disk group as follows:

    • Enter the disk group name (for example, DG1).

    • Check the Create cluster group check box if you wish to create cluster dynamic disk groups that are used in a shared storage environment.

    • Select the appropriate disks in the Available disks list, and use the Add button to move them to the Selected disks list.

      Optionally, check the Disk names prefix checkbox and enter a disk name prefix to give the disks in the disk group a specific identifier.

      For example, entering TestGroup as the prefix for a disk group that contains three disks creates TestGroup1, TestGroup2, and TestGroup3 as internal names for the disks in the disk group.

    • Click Next.

    Note:

    Windows Disk Management Compatible Dynamic Disk Group creates a type of disk group that is created by Windows Disk Management (LDM).
  7. Click Next to accept the confirmation screen with the selected disks.
  8. Click Finish to create the dynamic disk group.
