Hi,

The odd thing is that dropping into a shell and using lsblk shows the target RAID volume and another on the same controller as /dev/sda1 and /dev/sdb1. The RAID partitions also appear in the output of `cat /dev/partitions` ...
This is a problem for the installer. The running RAID blocks the two disks and makes them unusable for the installer. While the installer is smart enough to handle some cases, like Linux software raid it uses itself, it isn't smart enough to shutdown every raid implementation.
To make the installer work you have to disable the RAID or zero out the metadata (either at the start or end of the disk) so no raid is started. The disks should then appear in the installer. The installer needs to see a plain /dev/sda, /dev/sdb, ... instead of /dev/cciss/c0d0 and similar.
Hope that helps, Goswin von Brederlow
