UE3500 installed with the Solaris 2.6 3/98 or 5/98 
End User Cluster will fail to boot with a message similar
to:

cannot load drivers for
sbus@2,0/sunw,socal@c,10000/ss@0,0/ssd@w21000020370eaf1c,0:a


This will be seen if any cluster lower than Entire Distribution
is selected.

You can install just the End User Cluster or any cluster lower than
Entire distribution of Solaris 2.6 3/98 or 5/98 on an Ultra Enterprise 
3500, but you must also add the SUNWssadv and SUNWhea packages to make 
it work.  

	SUNWhea		SunOS Header Files
	SUNWssadv	SPARCstorage Array Drivers

During the installation of Solaris 2.6 3/98 or 5/98, select the 
Customize software button and select the SUNWssadv and SUNWhea 
packages.  Adding these two packages will allow the installation to boot.
