HP-UX

Overview

HP-UX is HP’s Unix operating system. First released in 1986 on the HP 9000/500 series with HP FOCUS CPUs, HP-UX in its current version 11i runs on most PA-RISC 1.1 and 2.0 and Itanium 2 computers from HP.

Until version 9.x HP-UX had very strong BSD Unix influences (and supposedly was very close to HPBSD); from versions 10.x onward it became more close to the System V line of Unix (SVR4). The PA-RISC version of HP-UX including 10.20 were split into different releases for workstations (HP 9000/700) and servers (800). HP-UX 10.20 was quite popular, since it ran very smoothly on older systems and had support for most available PA-RISC hardware.

From HP-UX 11.00 onward, unified releases were made for servers and workstations (700s and 800s). The 11 line of HP-UX was the first complete 64-bit version with support for the 64-bit features 64-bit PA-8x00 processors.

HP-UX 10.20

HP-UX 10.20 is quite fast on all supported machines with at least 64 MB RAM. Most administration tasks can be done using the sam system administration manager: e.g., adding devices, configuring the kernel, X server, network and mounting filesystems.

Different releases were made for HP 9000/700 workstations and the HP 9000/800 servers.

HP-UX 11.00

Version 11.00 is HP’s first Unix to implement a full 64-bit kernel. Nevertheless, it still runs on a number of systems featuring a 32-bit CPU. All HP 9000/800 servers with at least a PA-7000 should be supported, although some expansion options have been discontinued for those systems. Official support for HP 9000/700 workstations was only continued for those systems featuring at least a PA-7100LC CPU. With careful review of the newer OS patches older systems with e.g., PA-7100 and PA-7150 CPUs can also be made to run 11.00.

11.00 can run in either 64-bit or 32-bit mode on systems with a PA2.0 processor (i.e. at least PA-8000) or in 32-bit mode on all PA1.1 processors.

HP-UX 11i

Version 11i is the latest HP-UX release for PA-RISC and Itanium based computers. There are different versions of HP-UX 11i targeting different system families.

↑ up

HP-UX 11i v1 (11.11)

The original HP-UX 11i release supporting most 64-bit PA-RISC systems and many older 32-bit servers and workstations. Some even older 32-bit PA-RISC systems were officially unsupported but could be made to work with some v1 releases.

Supported systems

HP-UX 11i v1.5 (11.20) and v1.6 (11.22)

Special HP-UX 11i versions supporting the first generation Itanium and several early Itanium 2 systems.

HP-UX 11i v2 (11.23)

11i v2 supports the later 64-bit PA-RISC servers (with rp-designations) and Itanium 2 servers and workstations

HP-UX 11i v3 (11.31)

HP-UX 11i release: similar to v2 but supporting only the latest 64-bit PA-RISC servers and Itanium 2 servers.
