Alex,

try a minimum boot using >>> B/1 and then in SYSBOOT> SET STARTUP_P1 "MIN"
This will skip execution of SYSTARTUP_VMS.COM and should allow you to log in on OPA0:

Comment out UCX$STARTUP, reset STARTUP_P1 to "" and reboot.

Then try to manually execute UCX$STARTUP, if it hangs, you can now abort it via CTRL-Y
