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@xxxxxxxxxx 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:
