Creating a Dynamic Disk Group

The New Dynamic Disk Group procedure creates an additional dynamic disk group. Disks must be placed in dynamic disk groups before they can be used by VxVM. The default disk group (rootdg) is usually created during VxVM installation and always exists on a system running VxVM. You can create additional dynamic disk groups to organize your disks into logical sets of disks.

When you place a disk under VxVM control, the disk is initialized. Initialization destroys any existing data on the disk. (If your system supports encapsulation, you can use encapsulation to preserve disk data.)

The steps for creating a new dynamic disk group are:

Select the Disk Groups folder, or select a disk.
Select Actions > New Dynamic Disk Group.
The New Dynamic Disk Group wizard screen appears.
Click Next to continue. A new screen appears.
Enter a name for the dynamic disk group and select which disks you want to include in the group. Make sure the disks you want to include are in the right pane of the window, and click Next.
When you have provided all necessary information in the dialog box, click OK.
The next screen confirms the disks you have selected. Choose Next to continue if you are satisfied with the disk selection. If you are not satisfied, you can click the Back button to go back to the previous screen in order to modify your disk choices.
Normally, you would add all the disks you want in the group at this point. You can always add more disks later with the Add Disk to Dynamic Disk Group command.




	NOTE: The New Dynamic Disk Group task requires a dynamic disk group name and the name of at least one disk. The dynamic disk group name must be unique. The new dynamic disk group must contain at least one disk. Only disks that are online and do not belong to a dynamic disk group can be used to create a dynamic disk group. The Volume Manager disk name must be unique within the dynamic disk group. If multiple disks are specified in the Disk Device(s) field and only one disk name is specified in Disk Name(s) field, VxVM appends numbers to the disk name so that each disk name is unique within its dynamic disk group.
