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

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

       /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: Limits  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, rootdg is presumed.  Changes the default for subsequent volume
       creation,  depending  on the option argument. If the option argument is
       yes, all subsequent volumes created using the  volassist	 command  will
       automatically  be  created  as mirrored volumes. If the option argument
       supplied is no, mirroring will be turned	 off  for  future  volumes  by
       default.	  Displays  current default status for mirroring.  Mirrors 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 unmirrored 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.

       The volmirror command is generally called from the voldiskadm menus. It
       is not an interactive command and once called, will continue until com‐
       pletion of the operation or until a failure is detected.

					Note

       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  sup‐
       plied  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 mirror‐
       ing  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 these 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.  The
       following command mirrors the contents of the disk named disk01 to  any
       available  space	 on  any available disk. Subsequent calls to volassist
       will cause created volumes to be mirrored by default.  volmirror -d yes
       disk01  The  following  command	displays the current status of default
       mirroring. It prints the string yes if mirroring is  currently  enabled
       or  no, if not.	volmirror -D The following command mirrors any volumes
       on disk02 onto disk03.  volmirror disk02 disk03
