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 ?

You can try

Code:
# zpool split

if your release has that functionality.

This function is starting with release 9, while my release is 7.
If I shut down server and remove disk (physically) from server and then bring up server, that should work ?
And if this works, how will I attach (resynch) both disk after my activity got completed and I reinserted disk inside server ?
