Add or Initialize Disks
Menu: VolumeManager / Disk / AddDisks
Use this Operation to add one or more disks to a disk group. You can

That Will BE CREATED AS A Part of The Operation. The SELECTED Disks MAY
Also Be Added to a Disk Group As Spares. or the may be added asnohotuses to be eluded from hot-relocation us. The success
Disks May Also Be Initialized without adding the to a disk group
Leaving the disks available for use as replacement disks.
More Than One Disk Or Pattern May Be Entered At The Prompt. Here Are
Some Disk Selection Examples:
All: All Disks
C3 C4T2: All Disks on Both Controller 3 And Controller 4, Target 2
C3T4D2: a Single Disk (in the c # t # d # naming scheme)
XYZ_0: a Single Disk (In the Enclosure Based Naming Scheme)
XYZ_: All Disks on The Enclosure Whose Name IS XYZ

You can choose to add this disk to an existing disk group, a
New Disk Group, or Leave the Disk available for use by future
Add or Replacement Operations. TO CREATE A New Disk Group,
SELECT A Disk Group Name That Does Not Yet Exist. To Leave
The Disk Available for Future Use, Specify A Disk Group Name
Of "none".

2. Set the shared disk group

This step needs to be performed on the Master node
# vxdg Deport ORADG
# vxdg -s import orad
# vxdg list
