volmirror(8) System Manager's Manual volmirror(8)
NAME
volmirror - Mirrors 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: 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
completion 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 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 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
FILES
The defaults file for volassist parameters.
