I have an alphastation 600 with DU 4.0D and just added a Seagate 18.2 GB ultra-SCSI external 
disk drive -- my first such experience.  I installed and partitioned the disk and can use it 
now, but the installation was less than smooth as it wasn't clear to me -- and still isn't -- as 
to where the Dynamic Device Recognition leaves off and where I get involved.  The documentation 
isn't clear on this issue.  This is what I did:
1. After I installed the drive and powered up ( external drive was turned on first), the disk 		
   wasn't initially recognized by the system.  It should have been, right?  I ended up rebooting 
   using genvnumix, and when I did the disk was recognized and the MAKEDEV had been done.  The   
   DEC System docs say that a reboot isn't necessary with DDR.  What am I missing?
2.  Since I rebooted with genvmunix, I thought I might have to edit the configuration file DELTA
    to include the new device.  I ran sizer and found the entry 
    #UNSUPPORTED  msb0   at eisa0   slot 4       in /tmp/DELTA
    
    I changed this to:  device disk  msb0   at eisa0   slot 4  (in DELTA)
     and tried to rebuild the kernel with doconfig -c DELTA.  This didn't get far so I took out 	
     the new device entry and tried again, this time successfully.  Apparently the               
     configuration file doesn't need the new entry since the device was already recognized. 
     
3.  I went on to label and partition the drive with the widget, then made a file system with     
    newfs and mounted it.  
Although the disk is working, my experience has left me wondering how a "proper" installation 
should go.  I'd appreciate any advice on how to procede with my next disk installation, and 
comments on exactly what DDR does.
TIA
