†VAX specific
Compaq recommends that you define logical names for system components (for
example, public disks and directories) in executive mode, using the /EXECUTIVE_
MODE qualifier with the ASSIGN or DEFINE command. This type of logical
name, known as a trusted logical name, is available during system operations
such as the activation of privileged mode images (LOGINOUT, Mail, and so on).
For detailed information about logical name assignments and the privilege modes
(executive, kernel, supervisor, and user), refer to the OpenVMS User’s Manual.
How to Perform This Task
1. Invoke any editor to edit the file SYS$MANAGER:SYLOGICALS.COM.
2. Add logical name definitions in the following format to the end of the file,
immediately preceding the EXIT command:
DEFINE/SYSTEM/EXECUTIVE/NOLOG logical-name equivalence-name
For example:
DEFINE/SYSTEM/EXECUTIVE/NOLOG FINANCE_DISK DRAC$DRA2:
For more information about the DEFINE command, refer to the OpenVMS
DCL Dictionary.
3. Exit the editor to create a new version of the file. The highest version will
automatically be invoked by STARTUP.COM each time the system boots.
Example
$ DEFINE/SYSTEM/EXECUTIVE/NOLOG FINANCE_DISK DRAC$DRA2:
$ DEFINE/SYSTEM/EXECUTIVE/NOLOG SYSDSK SYS$SYSDEVICE:
In this example, any user on the system (and any program running on the
system) could use the name FINANCE_DISK (the logical name) in place of
DRAC$DRA2: (the physical device name). Similarly, you can refer to the system
disk (SYS$SYSDEVICE:) as SYSDSK.
