[SunHELP] sd.conf syntax (reducing boot time)

Is there any way to restrict target/lun definition in sd.conf to a
particular SCSI controler ?

Explanations: 

I have an EMC3930 disk array with 8 SCSI channels, with 78 disks on each
channel, each channel having 1 distinct  target with 78 luns:
c8t2d0        to   c8t2d77
c20t10d0    to   c20t10d77
etc...

sd.conf  has 8 * 78 entries for the array :    
 target 2 :   lun 0 to 77
 target 10 : lun 0 to 77


The problem is that during each boot sequence, each target/luns is inquired
on EACH controler,  although it exists only on one particular controler.
The consequence is a huge boot time, due to timed-out inquiries.

I'm looking for an extra option in sd.conf to say :

controleur 8 target 2 lun 0-77
controleur 20 target 10 lun 0-77


Thanks for any help.
