Hi Andre,

I would check your initrd for the proper modules (sata_*.ko maybe?). It
sounds like they aren't getting loaded via the init script in your
initrd.

Do you have an "alias scsi_hostadapter <something>" line in your
/etc/modprobe.conf file?

The /dev/mapper/* devices are getting created because "vgscan" and
"vgchange -ay" isn't finding any volume groups (the SATA disk can't be
found).

Subject: [rhelv5-list] rhels5.1 dev-mapper and raid1

Hi,

On a HP Proliant dl-140-g3 with Adaptec SATA controller I'm trying to
install RHELS5.1 . Both SATA disks are configured in a RAID 1 set (via
the SATA controller internal setup utility), properly recognized as 1
device during RH installation and mapped in /dev/mapper . Creating a
/boot partition and a LVM2 VG group on the dev-mapper device. All going
well, but when rebooting the system after installation, it does not
setup de dev-mapper device. RH sees both disks as separate disks
(/dev/sda and /dev/sdb), not as during installation as a device-mapper
device. Any ideas how to correct this?

Tia,
Andre
