can you check the behavior of your KDB50 during booting?

Hi, I am having a problem around the KDB50 of one of my VAX6k's
and need your help. If you boot from a KDB50, could you check if
the yellow indicator LEDs turn OFF for the moment that the drive is
first accessed? I am getting the error, device not accessible.
I could boot from that same path before until the moment that
I connected another RA92 and an RA81 and I switched the drive
unit numbers of two of my RA90s around. After I swapped those
unit numbers I can't get any of the drives to boot any more. My
fear is that somehow the KDB50 is dead.

So, next time you bood your VAX through a KDB50, plese watch the
yellow indicator LEDs closely. Mine go on in the early initialization
process and stay on throughout the self test. Then when the boot
sequence is entered those lights go off for a few seconds, the
red FAULT light goes on at the console. After one or two seconds
the yellow indicator LEDs go back on and FAULT light clears. Then
the typical blink pattern of the little red LED is engaged, but
at that time the VAX is already halted with that I/O error.

thanks,
-Gunther
