AHA-29160 in SPARC-Server

[Mischa Simon]

Hi everyone,

I bought a used Sun Enterprise 250 and installed my Adaptec AHA-29160 as
second SCSI card and installed Ubuntu 7.04 for Sparc on drive0
(/dev/sda) attached to the first (internal) SCSI device. 

lspci tells me:
0000:80:00.0 Host bridge: Sun Microsystems Computer Corp. Psycho PCI Bus
Module
0001:00:00.0 Host bridge: Sun Microsystems Computer Corp. Psycho PCI Bus
Module
0001:00:01.0 Bridge: Sun Microsystems Computer Corp. EBUS (rev 01)
0001:00:02.0 SCSI storage controller: Adaptec AIC-7892A U160/m (rev 02)
0001:00:03.0 SCSI storage controller: LSI Logic / Symbios Logic 53c875
(rev 14)
0001:00:03.1 SCSI storage controller: LSI Logic / Symbios Logic 53c875
(rev 14)
(and some more)

but lsscsi is only:
[0:0:0:0]    disk    FUJITSU  MAG3182L SUN18G  1111  /dev/sda
[0:0:5:0]    tape    HP       C1537A           L706  /dev/st0
[0:0:6:0]    cd/dvd  TOSHIBA  XM6201TASUN32XCD 1103  /dev/scd0
[0:0:8:0]    disk    FUJITSU  MAG3182L SUN18G  1111  /dev/sdb

but there should be two more Seagate hdds present (attached to the
AHA-29160). 

How can I tell my ubuntu that there is a second scsi card installed and
load the driver and the drives?

Thanks for your help.
