Hi

I am with one problem that I couldn't find solution at the intenet. 

My server is HP ML 110 G5 with Embedded Raid. By lspci , I can see that
it's a  "RAID bus controller: Intel Corporation 82801 SATA RAID
Controller (rev 02)". I am using centos 5

I can see that RAID is not working because there isn?t volume at
/dev/mapper/, just "control".

"[Backup_DrClin ~]# cd /dev/mapper/

[Backup_DrClin mapper]# ls

control

[Backup_DrClin mapper]#"

The device mapper was load at boot:

[Backup_DrClin log]# grep device-mapper dmesg

device-mapper: uevent: version 1.0.3

device-mapper: ioctl: 4.11.5-ioctl (2007-12-12) initialised:
dm-devel at redhat.com

device-mapper: multipath: version 1.0.5 loaded

[Backup_DrClin log]#

I Try to activate dmraid, but no work:

[Backup_DrClin mapper]# dmraid -ay

RAID set "ddf1_Raid_1_Mirror" was not activated

ERROR: device "ddf1_Raid_1_Mirror" could not be found

[Backup_DrClin mapper]#

I can see at logs : (/var/log/messages

Feb  3 08:31:35 Backup_DrClin kernel: device-mapper: table: 253:0:
mirror: Device lookup failure

Feb  3 08:31:35 Backup_DrClin kernel: device-mapper: ioctl: error adding
target to table

Feb  3 08:31:35 Backup_DrClin kernel: device-mapper: ioctl: device
doesn't appear to be in the dev hash table.
