1.1 Key Terms

Table 1-1 lists a few key terms you need to know before you install or upgrade the system.

Table 1-1 Definitions of Terms


HP Integrity Virtual Machines (Integrity VM)

Integrity VM is a soft partitioning and virtualization technology that provides operating system isolation, with sub-CPU allocation granularity and shared I/O. Integrity VM can be installed on an Integrity server or a hardware partition (nPartition) running HP-UX. OpenVMS can be one of the guest operating systems supported.

HSx device

A self-contained, intelligent, mass storage subsystem that lets computers in an OpenVMS Cluster system environment share disks. The disk on which you install or upgrade the operating system can be connected to one of these systems (for example, an HSV or HSG).


A general-purpose disk storage server. For OpenVMS Alpha systems, the InfoServer may be an independent hardware device or, beginning with OpenVMS Version 8.3, it may be a utility (software application) on an OpenVMS system. On OpenVMS Integrity server systems, the InfoServer is only available as a software application on an OpenVMS system.

The InfoServer hardware can serve CDs only (it does not support DVDs); thus, this hardware device cannot serve the OpenVMS Integrity servers operating environment (OE) DVD. The InfoServer utility can serve both DVDs and CDs (for OpenVMS Integrity servers and OpenVMS Alpha systems, respectively). The systems connected to the same LAN can use the InfoServer utility to boot the OpenVMS operating system from a virtual drive (instead of the local drive). For more information about the InfoServer utility, see the HP OpenVMS Version 8.4 New Features and Documentation Overview.

local drive

A drive on your computer system, such as a CD, DVD, or disk drive (hard drive), that is connected directly to the computer. If you have a standalone computer, it is likely that all drives connected to the computer system are local drives.

operating system media

The OpenVMS Alpha operating system CD or the OpenVMS for Integrity servers Operating Environment DVD (OE DVD) included with an OpenVMS distribution kit, which contains the OpenVMS operating system and the installation and other procedures described in this manual.


Using HP Systems Insight Manager (HP SIM), the process of installing or upgrading OpenVMS on one or more Integrity servers automatically. HP SIM initiates the process and the installation or upgrade automatically continues in the background.

source drive

The drive that holds the operating system media during an upgrade or installation. This can be a local drive or an InfoServer virtual drive. The drive contains the OpenVMS Alpha operating system CD or the OpenVMS for Integrity servers Operating Environment DVD, or a copy of it.

system disk

The disk from which OpenVMS is typically booted. During an installation or upgrade, this is the target disk because it receives files from the source drive. After installation or upgrade, the target drive is booted and becomes the system disk.

target drive

The drive that holds the target system disk during the upgrade or installation. Note: the target drive must be a hard drive, not a CD or DVD.

Virtual KVM (vKVM)

Virtual keyboard, video, and mouse feature included with Integrated Lights Out (iLO) 2 Management Processor (MP) on Integrity servers (rx2660, rx3600, and rx6600 Integrity servers and the BL860c and BL870c Server Blade products). The feature allows you to connect a virtual serial line from your PC to Integrity servers, enabling your PC, keyboard, and mouse to function as if directly connected to the server. Your window displays the contents of the Integrity server's VGA.

virtual media (vMedia)

A virtual-disk capability included with Integrated Lights Out (iLO) 2 Management Processor (MP) on Integrity servers. vMedia provides virtual devices that mimic physical hardware devices. For example, it can provide a virtual CD/DVD drive that emulates the DVD drive on a PC and connects over the network to your Integrity servers as if it were physically connected. You can use vMedia to install OpenVMS on Integrity servers that do not include a built-in DVD drive or that are physically located elsewhere. vMedia can provide the network service for HP SIM provisioning, or it can be used independently of HP SIM.
