System Cloning

Cloning allows administrators to take a snapshot of a fully installed and configured system. Later, administrators can

automatically install and configure other systems without the need to go through the set of installation and configuration

steps. After a system's configuration has been saved, administrators can apply it manually or automatically to other systems

at any time.

System cloning combined with user-defined scripts, which allow for customized scripts to be executed during different

phases of the installation process, allow administrators to perform an unattended installation and configuration of a system.

Administrators can use cloning for repetitive installations and configurations on multiple systems.

Remote Installation Service (RIS)

The Tru64 UNIX Server Extensions includes the Remote Installation Service (RIS). The RIS sets up a framework on a Tru64

UNIX server system that enables other Tru64 UNIX client systems to do a full, update, or cloned installation (except New

Hardware Delivery) of the operating system software and the Worldwide Language Support software over the network from

the server system. Additional software (part of option software) can be loaded onto the client system from the RIS server

system after the client has been installed. BOOTP is the boot protocol used to initiate the installations. Because of the high

bandwidth requirements, RIS is supported only in local area network environments that use Ethernet, Gigabit Ethernet,

FDDI, and Token Ring network addresses.

A RIS client can be booted from the following interfaces:

Internal Ethernet

The DE422 and DE425 EISA Ethernet option cards

The DE203, DE204, and DE205 ISA Ethernet option cards

The DE434, DE435, and DE436, DE500, DE504, DE600, DE602 PCI Ethernet option cards

The DEFEA EISA family of FDDI option cards

The DEFPA PCI family of FDDI option cards

The DETRA Token Ring option card

Firmware Requirements for RIS Option Cards

Console firmware and all option firmware in the DMS or RIS server and in every client system must be compatible with the

version of Tru64 UNIX system software that will be running on that system.

See the Release Notes Overview included with the Console Firmware CD-ROM, which is packaged along with the Tru64

UNIX Operating System software kit (QA-6ADAA-H8), to determine firmware version compatibility.

Dataless Configurations

The Tru64 UNIX Server Extensions include support to install and operate systems in a dataless configuration. A server

system maintains the root, /usr, and /var file systems for all client systems. The server maintains one copy of root for each

client. The /usr file system is exported read-only and is shared by all clients registered in the environment. Each client has its

own /var file system. Dataless clients access the file systems maintained on the server using NFS. A minimum of one disk

drive is required on each client for dumping and swapping.

The Dataless Management Utility (dmu) enables the server to register and manage the software areas used by Tru64 UNIX

dataless clients. BOOTP is the protocol used to boot the clients and mount the remote file systems.
