Hi
Should be doable.

The easiest thing is to put the 18Gb disk into an external SCSI box and 
then connect it with the appropriate cable to the external SCSI connector 
which is present on most Suns earlier than the Ultra 5. Fitting it inside 
the chasis will depend on the type of SCSI disk and the model of Sparc box.

The following is what what SCSI connectors are on which Sparc machines. 
It's off the top of my head so could be somewhat wrong:

Sun SparcStations 1, 2, IPC, IPX 
	50 pin internal and 50 pin high density external
	(beware of running hot drives in the IPC and IPX boxes)

Sun SparcStations 4, 5, 10, 20
	SCA (80 pin) internal and 50 pin high density external

Sun Ultras 1, 2
	SCA (80 pin) internal and 50 pin high density external

Sun Ultras 5, 10
	No SCSI onboard - you'll need an addon card.


If the machine has had Solaris on it then the default boot device will 
probably be a internal hard disk with SCSI ID3. You can change this in 
the OpenBoot PROM, eg "boot disk1" if you've set the root drive to be 
SCSI ID1. You can make this permenant with "setenv boot-device=disk1". 
There is an OpenBoot FAQ at:

And the following sites will also be of use:
