2.6 Mirror volumes on a disk
volumes can be mirrored to another disk with available space however it can not be used to mirror existing mirrors or mirrors spanning more than one sub disk .

To mirror volumes on a disk, make sure that the target disk has an equal or greater amount of space as the originating disk and then do the following

Select menu item 6 (Mirror volumes on a disk) from the vxdiskadm main menu.

Mirror volumes on a disk
Menu: VolumeManager/Disk/Mirror

This operation can be used to mirror volumes on a disk. These
volumes can be mirrored onto another disk or onto any
available disk space. Volumes will not be mirrored if they are
already mirrored. Also, volumes that are comprised of more than
one subdisk will not be mirrored.

Mirroring volumes from the boot disk will produce a disk that can
be used as an alternate boot disk.

Enter disk name [,list,q,?] disk02

You can choose to mirror volumes from disk disk02 onto any
available disk space, or you can choose to mirror onto a specific
disk. To mirror to a specific disk, select the name of that disk.
To mirror to any available disk space, select “any”.

Enter destination disk [,list,q,?] (default: any) disk01

Note – Be sure to always specify the destination disk when you are creating an alternate root disk. Otherwise, the volume manager will select space available in the disk group which might span disk and will result in boot failure from this disk.
