volrootmir(8)
NAME
  volrootmir - Creates mirror of areas necessary for booting on a new disk

SYNOPSIS
  /usr/sbin/volrootmir [-a] [nconfig=count] [swap=target_disk] target_disk

OPTIONS
  -a  Specifies that all volumes relating to the boot disk be mirrored, not
      just the root and swap volumes, rootvol and swapvol.

  nconfig=count
      Specifies the number of log copies and copies of the configuration
      database; for example, nconfig=2.

  swap=target_disk
      Specifies that the swap volume, swapvol, be mirrored on a separate
      disk, specified by target_disk.

DESCRIPTION
  The volrootmir script creates a copy of all areas involved in booting on
  the specified target disk and adds those copies as mirrors to the relevant
  system volumes.

  When used without the -a option, volrootmir adds mirrors to the root and
  swap volumes only (does not mirror the volume for /usr or /var) and
  allocates them on the new disk. In addition, all disk regions required for
  booting are set up and partitions for the new volume mirrors are created.

  When used with the -a option, volrootmir mirrors all in-use partitions on
  the system disk.

  To mirror a swap volume that is on a separate disk from the root volume,
  use the swap operand to specify a separate target for the swap mirror.

  You can run this script from the voldiskadm menu by choosing the Mirror
  volumes on a disk operation.

RESTRICTIONS
  The volrootmir command is not supported in a cluster.

  The specified target disk for mirroring the boot disk:

    ·  Must not be under LSM control

    ·  Must have a disk label with all partitions marked unused

    ·  Must be as large as the partitions (on the boot disk) being mirrored
       plus the size of the private region (4096 blocks).

  If the swap partition is on a different disk than the boot disk, to mirror
  swap you need an additional disk that:

    ·  Is not under LSM control

    ·  Has a disk label with all partitions marked unused

    ·  Is at least as large as the swap space partition plus the size of the
       private region (4096 blocks)

  Specify a disk (not a partition) as the target for mirroring a swap volume,
  if the swap volume is on a separate disk.

EXAMPLES
   1.  The following command adds mirrors for the rootvol and swapvol volumes
       on the target disk, dsk3. This command will fail if swapvol is on a
       different disk from rootvol.

	    # volrootmir dsk3

   2.  The following command adds mirrors for rootvol, swapvol, and any other
       volumes on the root disk on the target disk, dsk3. This command will
       fail if swapvol is on a different disk from rootvol.

	    # volrootmir -a dsk3

   3.  The following command adds mirrors for rootvol on disk dsk3, swapvol
       on disk dsk7, and any other volumes on the root disk on disk dsk3.
       This command will fail if swapvol is on the same disk as rootvol.

	    # volrootmir -a swap=dsk7 dsk3

   4.  The following command adds mirrors for rootvol on disk dsk3 and
       swapvol on disk dsk7. This command will fail if swapvol is on the same
       disk as rootvol.

	    # volrootmir swap=dsk7 dsk3
