Hi,

Yesterday evening, I tested the debian-installer rc2 on a shared SCSI
system i.e.

node1 (no internal disks)
node2 (no internal disks)
box with shared SCSI disks (both nodes connected to the same bus)

Some notes:
* To avoid interference:
   - SCSI BIOS on node1 sees only SCSI IDs 2 and 3
   - SCSI BIOS on node2 sees only SCSI IDs 4 and 5
* The bootloader sees what the SCSI BIOS presents i.e. 2 disks.
* Linux itself recognises the 4 disks on each host[*]

[*] I don't know how I can tell Linux to ignore some disks.

As node1 was already installed some time ago, I only installed
node2. Installation took place on "/dev/sdc" and went fine. At the end
however, there is the question to install grub in the MBR or not. I
wondered what _the_ MBR was as both /dev/sda and /dev/sdb were already
bootable (RAID1 setup). As I was installing on /dev/sdc, I thought
that it would setup grub on the MBR of /dev/sdc, so I confirmed. I saw
that grub-install was called on hd0 so I knew something was wrong
i.e. it was writing to the MBR of /dev/sda. I corrected the problem on
node1 and installed grub manually on node2 (/dev/sdc) using a grub
floppy.

Question: Wouldn't it be good to present a list of disks so that the
user can select the disk whose MBR should be changed?


cu,
