Hi Joerg,

I've read all the responses to your post.  The reason they contain
questions and no answers is because you've provided insufficient detail
about your system and its RAID hardware.

This is the first example of insufficient information.  You need to
provide the model# of the Fujitsu/LSI HBA.

This is a technically incorrect description of what you have, and is the
reason for everyone's confusion.  You need to be technically accurate
here.  It sounds like what you have done is a create a RAID1 group of
two physical disks in the LSI firmware, and then on that RAID1 device
created 6 Virtual Disks.  Each virtual disk is exposed as a SCSI LUN.
Thus, the Linux kernel, the Wheezy installer, are seeing 6 disks.

Is this correct?  If not, please explain in detail what virtual devices
you are exposing from the LSI HBA.

Provide the LSI physical/virtual disk configuration information
requested above and we'll go from there.

However, the act of going through the steps required to gather said
information should inform you as to which device:partition the Lenny
installation resides on.  Once you know that device:partition number,
the rest should be straightforward.  Simply tell the Wheezy installer to
put its files on that partition.
