SYSBOOT> USE DEFAULT
The USE DEFAULT command specifies that default values should be used for all parameters.
3.
To avoid starting all layered products on a system that is not tuned for them, possibly causing
the system to hang, set the STARTUP_P1 system parameter as follows:
SYSBOOT> SET STARTUP_P1 "MIN"
4.
Enter the following command to ensure that the operating system does not record for
subsequent system reboots the STARTUP_P1 parameter change you made in step 3:
SYSBOOT> SET WRITESYSPARAMS 0
5.
Enter the following command to continue booting:
SYSBOOT> CONTINUE
6.
When the system finishes booting, determine which changed parameter caused the problem
and reset the parameter value. If you specified the value for the parameter in the AUTOGEN
parameter file MODPARAMS.DAT, fix the value in that file and run AUTOGEN. For more
information, see the HP OpenVMS System Manager's Manual, Volume 2: Tuning, Monitoring,
and Complex Systems.
7.
After your system runs for at least 24 hours, run AUTOGEN in feedback mode, following
the steps described in
. Be sure to examine the
AGEN$PARAMS.REPORT, as recommended. If necessary, modify system parameters as
instructed in
. If you need assistance, contact your software support
representative. Once you feel confident that the problem is corrected, and AUTOGEN has
been run through the SETPARAMS phase, reboot the system.

B.6.12.2 Booting Without Startup and Login Procedures
If the system does not complete the startup procedures or does not allow you to log in, you might
need to bypass the startup and login procedures. The startup and login procedures provided by
HP should always work. However, if you introduce an error when you modify the startup or
login procedure, you could accidentally lock yourself out of the system.
How to Perform This Task
1.
Begin the conversational boot by entering the following command at the EFI Shell prompt,
where fsn: (such as fs1:) is the device associated with the system disk:
Shell> fsn:\efi\vms\vms_loader.efi -flags 0,1
2.
Enter the following command at the SYSBOOT> prompt:
SYSBOOT> SET/STARTUP OPA0:
3.
Enter the following command to ensure that the operating system does not record for
subsequent system reboots the STARTUP_P1 parameter change you made in step 2:
SYSBOOT> SET WRITESYSPARAMS 0
4.
Enter the following command to continue booting:
