If you want to add more disks to a dynamic disk group after the group is created, use the Add Disk to Dynamic disk group command. You can also use this command to first create a new dynamic disk group and then specify the disks to be added to it.
To add a disk to a dynamic disk group
Optionally, check the Disk names prefix check box and enter a disk name prefix to give the disks in the disk group a specific identifier.
This identifier precedes a system-generated numeric ID that SFW uses to distinguish the disks in the disk group.
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 to continue.
If you want to create a new dynamic disk group to add the disk to, click New dynamic disk group. The New dynamic disk group window appears to let you indicate the disk group name and characteristics.
Details on the options for creating a disk group are available in the procedure on creating a dynamic disk group.
For each disk, information is provided on whether it contains volumes and whether it is updated. If it is not going to be updated, you will want to modify the selection.
You can also create a new disk group for the new storage.
You can also remove a disk from a disk group.
