How to Replace disk in a mirrored rpool in Solaris 10

Hi ,

would like to ask our experts here how to replace a failed disk in my rpool. Server is an  SUN FIRE X4170 M2 running on Solaris 10 9/10 s10x_u9wos_14a X86. Thank you so much for any help.

These is how my zpool and format output looks like.

# zpool status

 pool: rpool

 state: DEGRADED

status: One or more devices has been removed by the administrator.

       Sufficient replicas exist for the pool to continue functioning in a

       degraded state.

action: Online the device using 'zpool online' or replace the device with

       'zpool replace'.

 scrub: none requested
