Hardware to software RAID migration

We have hardware RAID configured on our T6320 server and two LDOMs are running on this server. One of our disk got failed and replaced. After replacemnt the newly installed disk not detected by RAID controlled so Oracle suggested to upgrade the REM firmware. As this is the standalone production server, we do not want to take risk on REM upgrade. So we are planning for migrating the h/w RAID to software RAID. Kindly suggest how to perform this migration without disturbing LDOMs running on this server.
