Create a dynamic cluster disk group with volumes on shared storage so that they can be shared between nodes in the cluster.
Part of the process of creating a dynamic disk group is assigning it a name. Choose a name that is unique to your environment. Make note of this name, as it will be required later.
To create dynamic cluster disk groups, use the Veritas Enterprise Administrator (VEA). The VEA can be invoked on one of the servers and can be used to connect to all the other servers. However, VEA can also be launched on client system and can be used to manage all the servers remotely.
Setting up a Microsoft failover cluster creates physical disk resources for all the basic disks on the shared bus. To use these disks when you create your SFW cluster disk groups, you must first remove the physical disk resources from the cluster. Otherwise, a reservation conflict occurs. After creating the SFW cluster disk groups, corresponding Volume Manager Disk Group (VMDg) resources are added to the cluster, under the available storage. The VMDg resource name corresponds to the cluster disk group name. You can then assign any of these resources to an application service group..
To create a dynamic (cluster) disk group
Select a profile if prompted.
In the Group name field, enter a name for the disk group (for example, INST1_DG).
Click the checkbox for Create cluster group.
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.
Windows Disk Management Compatible Dynamic Disk Group creates a type of disk group that is created by Windows Disk Management (LDM).
