Encapsulate one or more disks
Menu: VolumeManager/Disk/Encapsulate
  Use this operation to convert one or more disks to use the Volume Manager.
  This adds the disks to a disk group and replaces existing partitions
  with volumes.  Disk encapsulation requires a reboot for the changes
  to take effect.

  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

Select disk devices to encapsulate:
[<pattern-list>,all,list,q,?] list

DEVICE       DISK         GROUP        STATUS
c1t0d0       -            -            online invalid
c2t2d0       d2           mdg          online
c2t3d0       d3           mdg          online
c2t4d0       d4           mdg          online
c2t5d0       d5           mdg          online

Select disk devices to encapsulate:
[<pattern-list>,all,list,q,?] c1t0d0
  Here is the disk selected.  Output format: [Device_Name]
  c1t0d0
Continue operation? [y,n,q,?]  (default: y) y

  You can choose to add this disk to an existing disk group or to
  a new disk group.  To create a new disk group, select a disk group
  name that does not yet exist.

Which disk group [<group>,list,q,?] rootdg

Create a new group named rootdg? [y,n,q,?]  (default: y) y

Use a default disk name for the disk? [y,n,q,?]  (default: y) n

  disk names that will be specified interactively.
  c1t0d0

Continue with operation? [y,n,q,?]  (default: y) y

  The following disk has been selected for encapsulation.
  Output format: [Device_Name]
  c1t0d0

Continue with encapsulation? [y,n,q,?]  (default: y) y

Enter disk name for c1t0d0 [<name>,q,?]  (default: rootdg01) rootdg01

  A new disk group rootdg will be created and the disk device c1t0d0 will
  automatically after the next reboot.  To reboot execute the command:
shutdown -g0 -y -i6

Encapsulate other disks? [y,n,q,?]  (default: n) n

Goodbye.
root@pr-01:>/# shutdown -g0 -y -i6

it will reboot twice
