I have a machine that's been configured as follows using its BIOS tools:
SATA-0 is a 160 GiB drive used as boot SATA-1 and SATA-2 are both 500 GiB drives and were configured as a RAID-1 in BIOS.
When the system boots up, BIOS reports 1 160 GiB SATA drive, and 1 Logical volume as RAID-1 ID#0 500 GiB, which is what I would expect it to report, as the two drives are now raided together.
However, when I boot into the Centos installer and I get to configuring the partitions, it lists both sda, sdb, and sdc as available. Both sdb and sdc are 500 GiB. I would've expected to only see one drive for the RAID setup.
Can someone explain why I see both drives and how am I supposed to configure them? I thought if I configured the BIOS to raid them, I wouldn't have to do anything in the OS other than to format the thing and expect it to work.
