You can use a SCSI disk there, but then, depending on the model and
capacity, you need to set some parameters in /etc (IIRC some format.dat
file) to make it known to SunOS. Typically, those machines where used as
diskless clients from a bootp server with sufficient storage. The client
boots from the network and receives a tftpboot image which then pulls in
the SunOS kernel and uses NFS to mount some /export/root, /export/swap and
/usr file systems. /export/root and /export/swap are per-system instances
of the root file system and swap file for the client, /usr is usually
readonly for all clients.
Unless you have a boot media (QIC24 tape or floppies) and can hook an
external drive to the machine, you better set up a server for diskless
clients. This can also be a Sparc machine.

The above is correct behaviour. With the diag switch set to NORM, the
machine expects a keyboard/mouse and monitor; it will then usually wait
for a boot command at the ">" prompt. Typing "b le()" attempts to boot
from the server; "b st(0,,0)" would boot a QIC tape to be connected, "b
(0,3,0)/vmunix" should boot a disk connected to SCSI with normal settings
IIRC. You should also see a ">" prompt after self test at the serial
