dmraid does not recognize Intel ESRT2 drives

[Claudio Moretti]

I am trying to install Ubuntu Server on a server with a Intel S5000VSA motherboard, which carries an Intel ESRT2 RAID controller.
I have tried 2 configurations: RAID5 on 3 500GB SATA disks and RAID 1 on two of those, with the other disk set as RAID0
The installer is unable to activate those disks; in particular, with the previous RAID5 configuration the installer complained about the raid45 module missing; I have tried to rebuild the array with the RAID1 and RAID0 configuration, and now it is unable to activate the disks.
dmraid -s recognizes the arrays as ddf1 arrays, while I'm pretty sure they should be isw or lsi.

I'm attaching /var/log/syslog and the output of dmesg, dmraid -s and dmraid -s -ccc -d

You can see that dmraid segfaulted when trying to activate the devices, my guess is either because when it tried to detect the disks awk was missing, or because it is looking for the dm-raid45 module, which is no longer present in the kernel tree.

If you know of a way to solve this, please let me know.

Thanks,
Claudio
