how to make mirror rz8 and rz9

[mac2008_1]

当前系统盘是rz8,未做镜像，分了4个区

voldisk list
DEVICE TYPE DISK GROUP STATUS
rz10 sliced swapdisk rootdg online
rz11 sliced disk02 rootdg online
rz8a nopriv rz8a rootdg online
rz8b nopriv rz8b rootdg online
rz8e simple - - online invalid
rz8g nopriv rz8g rootdg online

我现在添加了1块盘rz9,并且分区大小已经按照rz8模式分好

# voldisk list
DEVICE TYPE DISK GROUP STATUS
rz10 sliced swapdisk rootdg online
rz11 sliced disk02 rootdg online
rz8a nopriv rz8a rootdg online
rz8b nopriv rz8b rootdg online
rz8e simple - - online invalid
rz8g nopriv rz8g rootdg online
rz9a nopriv rz9a rootdg online
rz9b nopriv rz9b rootdg online
rz9g nopriv rz9g rootdg online

现在我想把系统盘rz8 和rz9 做镜像，我该怎么做？？？

# volprint -ht -g rootdg
DG NAME GROUP-ID
DM NAME DEVICE TYPE PRIVLEN PUBLEN PUBPATH
V NAME USETYPE KSTATE STATE LENGTH READPOL PREFPLEX
PL NAME VOLUME KSTATE STATE LENGTH LAYOUT ST-WIDTH MODE
SD NAME PLEX PLOFFS DISKOFFS LENGTH DISK-NAME DEVICE

in short : you don't
You can mirror volumes not physical disks

looks like version v4.x ?
I'v no test system so i can't try the actual steps myself.

you may use "voldiskadm" (- Menu interface for LSM disk administration)
to
1. Add or initialize one or more disks
( add to the diskgroup)
6. Mirror volumes on a disk
