Dynamic Disk Group types available with VERITAS Volume Manager (tm) for Windows 2000 and VERITAS Storage Foundation (tm) for Windows

Solution



Three dynamic disk group types are available with Volume Manager for Windows 2000 (VM) and Storage Foundation for Windows (SFW):

1. Dynamic Disk Group
2. Cluster Disk Group
3. Dynamic Disk Group with Private Group Protection

The type of disk group is selected when the disk group is created (figure 1).

Figure 1 - New Disk Group
 

If not options are selecting while during the creation of the disk group, an SFW Dynamic Secondary disk group is created. If the option Create cluster group is selected, the disk group that will be created can be used in cluster environment. If the option Add Private Group Protection is selected, the disk group that is created contains disks from a shared SAN or storage array and provides hardware locking to the disks through a SCSI reservation thread. The Create Cluster Group option cannot be used with the Add Private Group Protection option. Lastly, the Create Windows Disk Management Compatible group creates a disk group that can be used with Windows Disk Management and earlier versions of VM. When creating a Windows Disk Management Compatible group, the option to Create cluster group can be selected as well. For more information about disk groups, please refer to the Veritas Storage Foundation (tm) Administrator's Guide in the Related Documents Section below.

Some differences between the three disk group types are listed below (table 1).
