Thanks for all the info, but I'm afraid that my sparc knowledge is 
insufficient here. Let's see if anyone on the debian-sparc list can help.

From the logs I can see that the esp_scsi module does get loaded, but it 
does not seem to detect anything at all. Either something is missing 
(basic scsi drivers?), or the hardware is just not supported by this 
driver. I've googled around a bit but that did not help either.

We sometimes advise to netboot sparc systems where the CD is not 
recognized, but that won't help if the harddisk is on the same 
bus/controller and needs the same driver.

Anyone any idea what could be missing or if this hardware is supported by 
linux at all? Here's basic hardware info; the installation report [1] has 
more extensive logs.

5-slot Sun Enterprise E3500, No Keyboard
OpenBoot 3.2.24, 4096 MB memory installed, Serial #12336266.
Ethernet address 8:0:20:bc:3c:8a, Host ID: 80bc3c8a.

{a} ok probe-scsi-all

Target 6 
  Unit 0  Removable Read Only device  TOSHIBA XM6201TASUN32XCD110312/12/97
Target e 
  Unit 0   Disk     SEAGATE ST373405LC      22033EK1BBDY

Once we figure out what's needed, fixing the installer to support that is 
probably trivial. The trick is in the first part.

Two things that may yet help:
- the output of lsmod after hardware detection (to see if anything obvious
  is not loaded)
- just manually trying to modprobe any driver under
  /lib/modules/../kernel/drivers/scsi and checking dmesg after each for
  some sign of life
