When I first brought up my LAVC some 6 months ago I had a similar problem.
Check to see if you have a process by the name CONFIGURE running on your
8300.  We have an 8530 and the process was absent.  It is the responsibility
of this process to find new served disks when they come on line and the
problem was that I had a "rich" SYCONFIG.COM that installed several drivers
and then had the line "$ STARTUP$AUTOCONFIGURE_ALL == 0".  This is OK with
a non-cluster system, but as one of the system management manuals points
out, if such language is used in a cluster environment, CONFIGURE does
not start up and your satellite disks cannot be seen.  BTW - if you reboot
your 8300 without shutting down the VAXstation you should then see the
missing disk(s).  Below is part of my SYCONFIG.COM file:
----------------------------------------------------------------
$!
$!      Site-specific device configuration procedure.
$!
      [---]
$ STARTUP$AUTOCONFIGURE_ALL == 0  <- the culprit
$ @SYS$SYSTEM:STARTUP CONFIGURE   <- the fix
