Comments/Problems:

The server has a DRAC (Dell Remote Access Card) which allows the remote administration
of the system and which provides virtual floppy and cd-rom drives. One of them (I suppose
the cd-rom one) is supported as removable scsi device.

The two SCSI disks are configured in RAID-1 with a SCSI RAID controller which requires the
metaraid_sas module. 

In the first part of the installation, this module wasn't loaded so the removable SCSI
device was /dev/sda and the SCSI disks weren't accessible. After the "Detect hard drives"
phase, the megaraid_sas module was loaded and the RAID-1 disk were detected as /dev/sdb.

After the first reboot, the machine failed to start:

1. The initrd didn't load the megeraid_sas module, so the disk wasn't detected.

2. After booting in rescue mode, adding megaraid_sas to the list of modules to load
   (/etc/initramfs-tools/modules) and run update-initramfs, the problem was that
   megaraid_sas was loaded before the removable SCSI module so the RAID disk was
   detected as /dev/sda instead of /dev/sdb.

3. After booting again in rescue mode and changing /etc/fstab to match /dev/sda,
   the system went up.

I wonder why the installer doesn't add megaraid_sas to the list of additional modules
for initramfs if it uses that module to detect the disks? And, in any case, this will
change the order of the disk devices depending on the order with the modules are loaded.

Thanks,
