NAME
  volmirror - Mirror volumes on a disk or control default mirroring

SYNOPSIS
  /usr/sbin/volmirror [-g diskgroup] [-d yes|no] medianame [new_medianame...]

  /usr/sbin/volmirror [-g diskgroup] [-d yes|no] -a  [new_medianame...]

  /usr/sbin/volmirror [-g diskgroup] [-d yes|no]

  /usr/sbin/volmirror [-g diskgroup] -D

OPTIONS
  The volmirror command supports the following options:

  -g diskgroup
      Limit operation of the command to the given disk group, as specified by
      disk group ID or disk group name.	 The medianame operands will be
      evaluated relative to the given disk group.  If no disk group is
      supplied to the volmirror command, then rootdg is presumed.

  -d  Change the default for subsequent volume creation, depending on the
      option argument.	If the option argument is yes, then all subsequent
      volumes created using the volassist command will automatically be
      created as mirrored volumes.  If the option argument supplied is no,
      then mirroring will be turned off by default.

  -a  Mirror all existing volumes for the specified disk group.

DESCRIPTION
  The volmirror command provides a mechanism to mirror all the contents of a
  specified disk, to mirror all currently un-mirrored volumes in the
  specified disk group, or to change or display the current defaults for
  mirroring.  All volumes that have only a single plex (mirror copy), will be
  mirrored by adding an additional plex.

  Volumes containing subdisks that reside on more than one disk will not be
  mirrored by volmirror.

  volmirror is generally called from the voldiskadm menus.  It is not an
  interactive command and once called, will continue until completion of the
  operation or until a failure is detected.  Due to the nature of generating
  mirror copies of volumes, this command may take a considerable time to
  complete.

  In the first listed form of the command, the disk media name is supplied on
  the command line to volmirror.  That name is taken to be the only disk from
  which volumes should be mirrored.  In the case of mirroring volumes from a
  specified disk, only simple single-subdisk volumes are mirrored.

  In the first and second listed forms of the command, the new_medianame ...
  parameter identifies a new disk media name or set of names.  The mirroring
  operation being performed will use the names as targets on which to
  allocate the mirrors.	 An error will result if the same disk is specified
  for both the source and target disk and if no other viable targets are
  supplied.

EXAMPLES
  The following are examples of the use of the volmirror command.

   1.  This invocation will cause the disk named disk01 to have its contents
       mirrored to any available space on any available disk.  Subsequent
       calls to volassist will cause created volumes to be mirrored by
       default:


	    /usr/sbin/volmirror -d yes disk01

   2.  This command will display the current status of default mirroring.  It
       will output the string yes, if mirroring is currently enabled or no if
       not:


	    /usr/sbin/volmirror -D

   3.  This will cause any volumes on disk02 to be mirrored to disk03:


	    /usr/sbin/volmirror disk02 disk03
