Customizing the Operating System
5.2 Modifying Site-Specific Startup Command Procedures
3. If necessary, add a MOUNT command to mount the disk or disks that are
to hold the secondary page and swap files. Disks other than the system disk
are not yet mounted at the time SYPAGSWPFILES.COM is invoked. For
information about the MOUNT command, refer to the MOUNT section of the
OpenVMS System Management Utilities Reference Manual.
4. Add the following command to make it easier to invoke SYSGEN:
$ SYSGEN := $SYSGEN
5. Add commands in the following format to SYPAGSWPFILES.COM to install
the secondary files each time the system boots.
For page files, use the following format:
SYSGEN INSTALL file-spec /PAGEFILE
For swap files, use the following format:
SYSGEN INSTALL file-spec /SWAPFILE
The INSTALL command activates secondary page and swap files. Page and
swap files not located in SYS$SYSTEM must be installed each time the
system boots.
Example
The following commands in SYPAGSWPFILES.COM install secondary page and
swap files on the device DUA10: with the logical name PAGE_SWAP:
$ MOUNT/SYSTEM/NOASSIST DUA10: SYS2 PAGE_SWAP
$ SYSGEN := $SYSGEN
$ SYSGEN INSTALL PAGE_SWAP:[SYSTEM]PAGEFILE1.SYS/PAGEFILE
$ if $status then write sys$output "Installed page file PAGEFILE1.SYS"
$ SYSGEN INSTALL PAGE_SWAP:[SYSTEM]SWAPFILE1.SYS/SWAPFILE
$ if $status then write sys$output "Installed swap file swapfile1.sys"
5.2.4 Modifying SYCONFIG.COM to Configure Devices
You can add commands to SYCONFIG.COM to perform site-specific device
configuration, including connecting nonstandard devices and suppressing
autoconfiguration.
5.2.4.1 Connecting Nonstandard Devices
Standard devices are automatically connected and configured by STARTUP.COM
each time the system boots. Nonstandard devices (devices not supplied by
Compaq) are not automatically connected and configured; you must connect
and configure these devices manually by entering certain commands. To
execute these commands each time the system starts up, add the commands
to SYCONFIG.COM.
On VAX systems, add SYSGEN CONNECT commands. For more information
about connecting devices, see Section 8.4. For more information about the
SYSGEN CONNECT command, refer to the SYSGEN section of the OpenVMS
System Management Utilities Reference Manual.
On Alpha systems, add SYSMAN IO CONNECT commands. For more
information about connecting devices, see Section 8.4. For more information
about the SYSMAN IO CONNECT command, refer to the SYSMAN section of the
OpenVMS System Management Utilities Reference Manual.
