Extend new disks in RAID1

ML350 G5 - E200i controller - SAS-disks
Windows SBS2003. OS on 2 separate disks.
Had 2 x 76 GB datadisks in RAID 1
Changed them 1 by 1 to now 146 GB
The ACU now see "the old 76 GB" + 70 GB unassigned.
Can I extend the array on the fly (and how ?)- or must I backup data, break the mirror, reconfigure and restore the BackUp ?
