Splitting rpool mirror disk in ZFS

Hi,

I have Solaris-10 (release-7) box without any non global zone. I have a very critical change after couple of days from application side. For safer side, we want to keep few level of backups just in case of faliure. This server is having three pool

Code:

root@prod_ddoa01:/# zpool list
NAME SIZE USED AVAIL CAP HEALTH ALTROOT
cvs_app_pool 165G 159G 6.50G 96% ONLINE -
iw_app_pool 1.11T 739G 400G 64% ONLINE -
rpool 136G 109G 26.6G 80% ONLINE -
root@prod_ddoa01:/#

I will create a lu copy with lucreate. Apart from it, can I pull one disk out of the server while I shut down the server ? Just in case of failure of application, I will pull out disk_0 and insert disk_1 (which was pulled out) and bring server up. Does it make sense ?
Also, I am not sure if lu will conflict with this procedure. And if I follow it, do I need to run some commands to break zfs rpool mirror ?

DPM-GETSPACEMD(1)					    DPM Administrator Commands						 DPM-GETSPACEMD(1)

NAME

       dpm-getspacemd - get space metadata

SYNOPSIS

       dpm-getspacemd --space_token s_token

       dpm-getspacemd [ --token_desc u_token ]

       dpm-getspacemd --help

DESCRIPTION

       dpm-getspacemd  gets  the  space  metadata  for a given space token or a space token description.  If none of the options is specified, the
       metadata for all the space tokens accessible by the user will be listed.  For each token, it displays three lines. The first one gives  the
       space token, the user description and the poolname associated with it.

       The second one gives the space usage restriction, either a DN or a list of VOMS FQANs.

       The  third  one	gives  the  size of the space, the amount of free space, the remaining space lifetime, the retention policy and the access
       latency.

       s_token
	      specifies the space token returned by a previous reservespace request.

       u_token
	      specifies the user provided description associated with a previous reservespace request.
