command console Alpha DS20E VMS7.3-2

[robert70]

How do you set the auto_action to "halt" from "restart". The Alpha reboots and doesn't allow me to see the >>> 3 chevron prompt? can you change console values at the dollar prompt $ when the system is up?

[robert70]

ignore my last question - resolved this with CTRL P - obvious when uou know how!

2nd question what console commands to I need to type to get the Alpha to boot of my system disk DKB0: when I type in BOOT at the 3 chevrons?
Currently the system has a semi boot eg I need to do a @sys$system:startup to complete? what value is et incorrectly for this?

[robert70]

my "boot_osflags" is set at 0
"boot reset" OFF
thanks

Roger,

to boot from DKB0 by default, use

>>> set bootdef_dev dkb0

If looks like your system is set for a minimum startup (STARTUP_P1="MIN"). You can correct this with:

>>> b -fl ,1 ! where =0 for [SYS0.]
SYSBOOT> SHOW STARTUP_P1 ! show current value
SYSBOOT> SET . ""
SYSBOOT> CONTINUE

or you can do this (for the next boot) from the DCL prompt:

$ MC SYSGEN
SYSGEN> USE CURRENT
SYSGEN> SET STARTUP_P1 ""
SYSGEN> WRITE CURRENT
SYSGEN> EXIT

[robert70]

that is set"" already?
it has happened since i did
b -fl 0,1
set/startup opa0:
set window_system 0
continue

Roger,

then you have to do:

>>> b -fl 0,1
SYSBOOT> SET/STARTUP=SYS$SYSTEM:STARTUP.COM
SYSBOOT> SET WINDOW_SYSTEM 1
SYSBOOT> CONT

You have a parameter called WRITESYSPARAMS, if you had done

b -fl 0,1
set/startup opa0:
set window_system 0
set writesysparams 0
continue

you would not have kept this value.

$ mc sysgen help sys_parameters writesysparams

SYS_PARAMETERS

WRITESYSPARAMS

On VAX systems, WRITESYSPARAMS indicates that parameters are
modified during SYSBOOT and are written out to VAXVMSSYS.PAR by
STARTUP.COM.

On Alpha systems, WRITESYSPARAMS indicates that parameters are
modified during SYSBOOT and are written out to ALPHAVMSSYS.PAR by
STARTUP.COM.

This special parameter is used by HP and is subject to change. Do
not change this parameter unless HP recommends that you do so.

WRITESYSPARAMS is a DYNAMIC parameter.

If you use "@sys$system:shutdown" and answer NO to the reboot prompt the console will settle to the ">>>" prompt. You can also use the halt button (leave enabled) to pause the automatic restart cycle.
