df -h shows /dev/mapper/ddf1...devices


i installed RHEL 5.7 on DL 320 G5 server. i configured RAID 1 on adapter ICH7 SATA RAID Embedded controller from BIOS. it correclty setup as RAID1 i can see while booting. In BIOS controller name is
Intel® 82801GR Integrated Serial ATA Host Controller

while installation it showed me /dev/mapper/ddf1 devices to configure. after installation i can see in df -h, long device name format.

you can see attachment.

and under fdisk -l. it showed two seperate disk. i.e /dev/sda and /dev/sdb. each with 160 GB .
see attachment for long device name format.

i can see using dmraid command ddf devices are mapped to /dev/sda and /sdb respectively.

so i need cciss driver for above controller.

kindly help
