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:
1. Select the Disk Groups folder, or select a disk.
2. Select Actions > New Dynamic Disk Group.
The New Dynamic Disk Group wizard screen appears.
3. Click Next to continue. A new screen appears.
4. 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.
5. 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.
6. 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.
