intel matrix raid - how to recover failed harddisk

[dynason]

I have installed centos 5.1 on ich9do with two identical sata harddisks installed. bios raid is configured as raid 1.

if one disk failed, how to recreate the raid disk set and recover all data to the new HDD?

below is the info from dmraid
[root@dhcppc2 ~]# dmraid -r
/dev/sda: isw, "isw_bcccehjebj", GROUP, ok, 625140333 sectors, data@ 0
/dev/sdb: isw, "isw_bcccehjebj", GROUP, ok, 625140333 sectors, data@ 0

[root@dhcppc2 ~]# dmraid -s
*** Group superset isw_bcccehjebj

name : isw_bcccehjebj_Volume0
size : 625133824

You will need to enter the raid bios, shown at bootup and start the process of rebuilding from there.

And what is the way to see the rebuild status?
