Notes:
• This task requires a disk group name and the name of at least one
disk.
• The disk group name must be unique.
• The new disk group must contain at least one disk.
• Only disks that are online and do not belong to a disk group can be
used to create a disk group.
• The Volume Manager disk name must be unique within the 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, the Volume Manager
appends numbers to the disk name so that each disk name is unique
within its disk group.
