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 ?

Specifies the name of the BIND zone for the named-xfer daemon to transfer, for example, dec.com. This option is required to pull a zone. Specifies the name of the file into which the pulled zone information is placed. This option is required to pull a zone. Specifies the current serial number of the SOA record for the zone zone_to_transfer. If serial_no is set to 0, the zone is always pulled. This option is required to pull a zone. Sets the debug level and determines the amount of debug information to be displayed. Specifies the file that will contain any debug messages from the zone pull.

See named(8) for more information. Specifies a list of Internet addresses, in dotted-quad format, from which to pull a zone. If the first host cannot be reached, the named transfer daemon tries to pull the zone from the next host listed. DESCRIPTION
The named transfer daemon, /usr/sbin/named-xfer, is a server that is usually run by the named daemon, /usr/sbin/named, but it can also be run manually with the given arguments. The named transfer daemon runs on a BIND secondary server and pulls BIND zones from a primary server. This daemon is not run by default, nor can it be started up from inetd(8). SEE ALSO
