HP BA322 90087 - Manual (Page 182)

NOTE: The file must be contiguous and movefile operations on the file must be disabled. If the
file is not contiguous, use the DCL command COPY/CONTIGUOUS (or similar) to re-create a
contiguous version of the file. To disable movefile operations, use the DCL command SET
FILE/NOMOVE. This prevents bootstrap failures that could result from the normal and expected
operations of disk defragmentation tools.
To start the Writeboot utility, enter the following command:
$ RUN SYS$SYSTEM:WRITEBOOT
The utility prompts you as follows:
Update VAX portion of boot block (default is Y):
Update Alpha portion of boot block (default is Y):
Answer N (NO) to the VAX prompt. If you answer Y (YES) to update the Alpha boot block, the
utility prompts you for the Alpha boot file:
Enter Alpha boot file:
Specify device-name:[VMS$COMMON.SYSEXE]APB.EXE in response to this prompt, where
device-name indicates the device on which the system disk is mounted. The utility writes the
specified information to the boot block on the system disk. For more information, see the HP
OpenVMS System Manager's Manual, Volume 1: Essentials.
