DEVICE       TYPE      DISK         GROUP        STATUS
c0t0d0s2     sliced    rootdisk     rootdg       online
c0t9d0s2     sliced    -            -            online
将c0t9d0加入到VxVm中：

# vxdiskadd c0t9d0

Add or initialize disks
Menu: VolumeManager/Disk/AddDisks

  Here is the disk selected.  Output format: [Device_Name]

  c0t9d0

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

  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".

Which disk group [<group>,none,list,q,?] (default: rootdg)

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

Add disk as a spare disk for rootdg? [y,n,q,?] (default: n)

Exclude disk from hot-relocation use? [y,n,q,?] (default: n)

  The selected disks will be added to the disk group rootdg with
  default disk names.

  c0t9d0

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

  The following disk device appears to have been initialized already.
  The disk is listed as added to a disk group, but is not currently
  active.  Output format: [Device_Name,Disk_Aclearcase/" target="_blank" >ccess_Name,Disk_Group]

  [c0t9d0,c0t9d0s2,rootdg]

Use this device? [y,n,q,?] (default: y)

  The following disk you selected for use appears to already have
  been initialized for the Volume Manager.  If you are certain the
  disk has already been initialized for the Volume Manager, then you
  do not need to reinitialize the disk device.
  Output format: [Device_Name]

  c0t9d0

Reinitialize this device? [y,n,q,?] (default: y)

  Initializing device c0t9d0.

Use a default private region length for this disk?
[y,n,q,?] (default: y)

  Adding disk device c0t9d0 to disk group rootdg with disk
  name disk01.

Goodbye.

  This operation will convert the following file systems from
  volumes to regular partitions:

        rootvol swapvol usr var

  Replace volumes in root disk to partitions.

  This operation will require a system reboot.  If you choose to
  continue with this operation, system configuration will be updated
  to discontinue use of the volume manager for your root and swap
  devices.

Do you wish to do this now [y,n,q,?] (default: y) y

  Restoring kernel configuration...

  A shutdown is now required to install the new kernel.
  You can choose to shutdown now, or you can shutdown later, at your
  convenience.

Do you wish to shutdown now [y,n,q,?] (default: n) y

  shutdown -g0 -y -i6

Shutdown started.    Tue May 10 18:07:01 CST 2005

Changing to init state 6 - please wait
