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

NAME
volrootmir - Mirror areas necessary for booting to a new disk SYNOPSIS
/usr/sbin/volrootmir [-a] [nconfig=count] target_disk [swap=target_partition] OPTIONS
Specifies that all volumes on the system disk be mirrored, not just the root and swap volumes, rootvol and swapvol. DESCRIPTION
The volrootmir script causes a mirror copy of areas of the root disk involved in booting to be made on the specified target disk. When used without the -a option, volrootmir adds mirrors of the root and swap volumes 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, the swap attribute must be used to specify a separate target for the swap mirror. The target disk(s) must be at least as large as the sum of the sizes of rootvol and swapvol. Also, the physical disk should not have any disk partition in use. This script can be called from the voldiskadm menus by choosing the Mirror volumes on a disk operation. ATTRIBUTES
Specifies the number of log copies and copies of the configuration database, for example, nconfig=2. Specifies that the swap volume, swapvol, be mirrored on a separate disk, as specified by target_partition. EXAMPLES
The following command mirrors the rootvol and swapvol volumes onto the target disk, dsk3. This command will fail if swapvol is on a differ- ent disk from rootvol. # volrootmir dsk3 The following command mirrors rootvol, swapvol, and any other volumes on the root disk onto the target disk, dsk3. This command will fail if swapvol is on a different disk from rootvol. # volrootmir -a dsk3 The following command mirrors rootvol on disk dsk3, swapvol onto partition dsk7d, and any other volumes on the root disk onto disk dsk3. This command will fail if swapvol is on the same disk as rootvol. # volrootmir -a dsk3 swap=dsk7d The following command mirrors rootvol onto disk dsk3 and swapvol onto partition dsk7d. This command will fail if swapvol is on the same disk as rootvol. # volrootmir dsk3 swap=dsk7d SEE ALSO
