Table 1-1 Definitions of Terms


HSx device

A self-contained, intelligent, mass storage subsystem that lets computers in an OpenVMS Cluster 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 I64 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, the hardware device cannot serve the OpenVMS I64 operating environment DVD.

The InfoServer utility can serve both DVDs and CDs (for OpenVMS I64 and OpenVMS Alpha systems, respectively). The systems connected to the same LAN can boot the OpenVMS operating system from a virtual drive (instead of the local drive) using the InfoServer utility. For more information about the InfoServer utility, see the HP OpenVMS Version 8.3 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 (OE) DVD included with your OpenVMS distribution kit, which contains the OpenVMS operating system and the installation and other procedures described in this manual.

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 booted. During an installation or upgrade, this is the source drive. After installation, 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.
