C Setting Up and Performing Network Booting
This appendix explains the steps required to enable your system to boot over the LAN using the
OpenVMS InfoServer utility, a software application available on OpenVMS Alpha (Version 8.3
or later) and OpenVMS Integrity servers (Version 8.2-1 or later) systems. It also describes how
to boot the virtual DVD/CD drive from the network.
C.1 About the OpenVMS InfoServer Utility
InfoServer network booting is supported for OpenVMS installations and upgrades on any
OpenVMS Alpha system and on any Integrity servers that support OpenVMS. For OpenVMS
Integrity server systems, InfoServer network booting is supported on all LAN cards (also referred
to as LAN devices or adapters) that are supported by EFI.
For both OpenVMS Alpha and Integrity servers Version 8.4 installations and upgrades, you can
boot from a virtual DVD/CD drive on the LAN using the OpenVMS InfoServer utility. You can
use the OpenVMS InfoServer software application on all Version 8.2-1 or later OpenVMS Integrity
server systems as well as on any OpenVMS Alpha Version 8.3 or later systems that support a
DVD drive. This support provides the additional advantage of allowing a network administrator
to upgrade multiple OpenVMS systems on the network from a single copy of the OpenVMS
distribution CD or DVD.
Using the InfoServer utility on Integrity servers for network booting requires several one-time-only
configuration steps unique to OpenVMS Integrity servers. Likewise, using the InfoServer utility
on OpenVMS Alpha servers requires an additional, one-time-only software configuration step.
Any configuration procedures that might have been performed for network booting using an
InfoServer hardware system (traditionally used by Alpha systems) are not valid for the OpenVMS
Integrity servers or OpenVMS Alpha InfoServer application.
Booting from the InfoServer utility for OpenVMS Integrity servers differs significantly from
booting from the InfoServer hardware system traditionally used by OpenVMS Alpha systems
or from the InfoServer utility on OpenVMS Alpha systems. For example, while Alpha systems
use the Maintenance Operations Protocol (MOP) to request the primary bootstrap file (APB.EXE)
to start the boot, the Integrity servers console uses the Intel Preboot Execution Environment
(PXE) bootstrap protocol in conjunction with the TCP/IP Services for OpenVMS BOOTP server
and TFTP. The Integrity servers EFI console first loads the primary bootstrap file
VMS_LOADER.EFI, which is formatted for EFI compatibility. VMS_LOADER.EFI then uses
TFTP to request the primary bootstrap IPB.EXE from the
boot server . IPB.EXE is formatted in
OpenVMS ODS file structure and is needed for booting the OpenVMS Integrity servers operating
system.
To install or upgrade the operating system over the network, OpenVMS Integrity server systems
must use the InfoServer utility that is integrated with the OpenVMS operating system. The
InfoServer hardware traditionally used by OpenVMS Alpha systems is not equipped to handle
DVD drives required for the OpenVMS Integrity servers distribution media. OpenVMS Alpha
systems can use the OpenVMS InfoServer utility or the traditional InfoServer hardware system
that is independent of OpenVMS. OpenVMS Alpha systems can boot from the distribution CD
on DVD drives (DVD drives support both DVDs and CDs).
Table C-1 summarizes the major
differences between Alpha and Integrity servers InfoServer booting.
