To Anyone Who Can Help:

I am having a problem when trying to boot after a power off.
I am running 4.2 BSD on a VAX 750.  I have one RP06 and one RM80
disk which I have set up as follows:
     RM80   -   hp0a   -  /
                hp0g   -  /usr
     RP06   -   hp1g   -  the users file system
              (I also have a backup boot on hp1a)

Up until six weeks ago these disks were the opposite of what they
are now -- the RP06 was hp0 and held / and /usr, the RM80 was empty
except for a boot (we had no users).  When I needed to establish users
on this system I switched the disks so that the RP06 would hold the 
users, since it was larger.

Since that time we have had three occasions where I had to bring
the system up from a complete power down.  Each time I have not
been able to boot off the RM80.  I get to the '%%' prompt and it
goes no farther.  Seems to me it's getting to the boot, but not
reading it.  The only way I have been able to bring the system up
is to make the RP06 disk 0, the RM80 disk 1, boot off the RP06, come 
up to single user, switch the disks back, halt the system then reboot.
When I do that it comes back up off the RM80.

I do not understand why I can't boot off the RM80 after the power
down.  If I shutdown the system at any other time (without powering
off) I'm fine and can boot from the RM80.

I mounted hp1a and did a 'sum' on that boot and the boot on hp0a--they
are the same.  The first time this happened the CE was here and I
talked to him about the problem.  He said he didn't understand what
was happening, but that it didn't make any sense.  I agree, it makes
no sense!!

Do any of you have any idea what's happening and what I can do about
it.
