volmirror - Mirrors volumes on a disk or control default
/usr/sbin/volmirror [-g diskgroup] [-d yes|no] medianame
/usr/sbin/volmirror [-g diskgroup] [-d yes|no] -a
/usr/sbin/volmirror [-g diskgroup] [-d yes|no]
/usr/sbin/volmirror [-g diskgroup] -D
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
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 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
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.
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
