HP-UX Unix on PA-RISC

Overview

HP-UX is HP’s commercial Unix operating system for its PA-RISC workstations and servers. First released during the 1980s for the earliest PA-RISC servers and their predecessors, the latest HP-UX in version 11i from the 2000s runs on most PA-RISC 1.1 and 2.0 and Itanium 2 computers from HP.

From the beginning, HP-UX was the Unix developed by HP for it’s HP 9000 800 Series servers and 700 Series workstations. Most PA-RISC computers were shipped with Unix and geared towards technical and business applications on Unix, including CAD, CAM, analysis and data processing.

HP-UX started as a server operating system and featured separate releases or separate versions for PA-RISC workstations, up to the popular HP-UX 10.20 from 1996. Starting with HP-UX 11.00, there were unified releases for servers and workstations. HP-UX 11.0 also marked the first complete 64-bit HP Unix with support for the features of 64-bit PA-8x00 processors.

Early HP-UX releases up to 9.0 were strongly based on BSD Unix and close to HPBSD. With HP-UX 10 onward, it became close to System V Unix (SVR4), a trend of the 1990s. There were many HP-UX Unix versions before that, from first PA-RISC HP-UX 1.0 in 1986 to HP-UX 9 in 1992.

HP-UX 11i

HP-UX 11i is the last HP Unix that was offered by HP for its PA-RISC and Itanium based computers. It was first released in 2000 and was developed into multiple different streams and operating systems over the years. There were different versions of HP-UX 11i targeting different system families and processors:

from archive.org

In these 11.x versions, HP distinguished between several operating environments (OEs) with different HP-UX functionalities: Minimal Technical Computing Operating Environment (TCOE) for workstations and servers as well as the Internet, Enterprise and Mission Critical OEs for servers. HP-UX 11i was called 11.11 before, when HP started another rebrand of products.

HP-UX 11i v3 (11.31)

HP-UX 11i v3 was released from 2007 onwards, it was similar to v2 but supported only 64-bit PA-RISC servers and Itanium 2 servers. Support for many other older servers was dropped, including even some of rp server family.

HP-UX 11i v2 (11.23)

HP-UX 11i v2, released in 2005, supported the later 64-bit PA-RISC servers with rp-designations and Itanium 2 servers and workstations. Support for 32-bit PA-RISC 1.1 systems was dropped completely along with many of the 64-bit PA-RISC 2.0 computers with only lettered model names (B-Class, C-Class).

HP-UX 11.00

Version 11.00 of HP-UX was the first 64-bit HP Unix, released in 1997. It ran on both 32-bit and 64-bit PA-RISC computers and supported most lettered servers and workstations plus some of the older 700s and 800s systems. 11.00 can run in either 64-bit or 32-bit mode on systems with 64-bit PA-RISC 2.0 processors like the PA-8000 or in 32-bit mode on all PA-RISC 1.1 processors. There was supposedly scant support for workstations in the original 1997 release of 11.00 that was developed by the HP Server division – to be added later with extensions.

Full 64-bit computing was defined as having a 64-bit CPU with 64-bit registers and data paths, 64-bit memory addressing, 64-bit Direct Memory Access, and a 64-bit kernel, required for high-performance, resource-intensive applications, and applications such as databases and OLTP that can use the scalability and memory addressing of 64-bit. HP-UX 11.0 was the first to do it on PA-RISC computers – first started on HP 9000 servers.

Features of HP-UX 11.00

In a similar vain to 32-bit HP-UX 10.20, there were Extensions Packs (EP) and Additional Core Enhancements (ACEs) that added support for hardware in HP-UX 11. Some 64-bit systems were only supported in 32-bit mode in original 11.00 from 1997, with 64-bit support added later.

HP-UX 11.0 supported many 64-bit workstations and most 32-bit PA-RISC workstations with at least PA-7100LC CPUs. Support for HP 9000 servers was generally solid with only very old 1980s servers unsupported that did not have at least a PA-7000.

HP-UX 10

©1996 HP, from archive.org

HP-UX 10 was the HP Unix version with the best performance and support for 32-bit PA-RISC workstations and servers. A variety of different versions were released by HP between 1995 and 1997 that however had a short shelf-life due to fears of possible Y2K bugs. HP offered an upgrade path to HP-UX 11 and exchange CDs for affected systems.

HP-UX 10 in its various guises supported almost all 32-bit 700 Series workstations, most of the lettered systems and still most of the older 800 Series servers. 10.01 was the last version to officially support PA-RISC 1.0 computers.

HP-UX 10.20

HP-UX 10.20 was released in August 1996, and was the HP Unix release that supported almost all 32-bit PA-RISC workstations and servers. For HP-UX, 10.20 was quite fast on all supported machines with at least 64 MB RAM. It was discontinued by HP in 2002 and obsoleted in 2003.

Features of HP-UX 10.20:

Different releases were made in HP-UX 10.20 for HP 9000 700 workstations and HP 9000 800 servers. Several extensions to 10.20 were shipped between 1997 and 1999 by HP to add hardware support, most often through HP-UX Additional Core Enhancements (ACEs).

  1. HP 9000 Servers (10.20): In July and August 1997, Hardware Extensions CDs were shipped to extend supported server systems to include T600, K370, and K570 servers and improve fibre-channel (FC) support
  2. HP 9000 Workstations (10.20): Additional Core Enhancements (ACEs) were shipped to upgrade hardware support and add new features to 10.20:
    • ACE 9912: B2000, C3600, J5600, J6000, J7000, VISUALIZE-fxe, IDE CD drives, USB devices
    • ACE 9906: B1000, C3000, and J5000 workstations and USB; Euro, LVD SCSI, Super I/O
    • ACE 9806: C360 workstation, PCI Visualize-EG graphics, Visualize-fx hardware texture mapping, Y2K fixes
    • ACE 9804: J2240 workstations
    • ACE 9802: Visualize-EG 2D, fixes for Y2K compliance,
    • ACE 9707: OpenGL; B132L+, B180L, C200, C240 workstations, Ultra SCSI, 100 Base-T Ethernet, Visualize-FX, OpenFL
  3. HP 9000 Servers (10.30): Released in 1997 with several updates and enhancements to 10.20, focused on 800 Series servers. It added kernel (POSIX) threads, support for NFS version 3 (PV3), streams in TCP/IP, ASE, PPP and Y2K compliance. HP-UX 10.30 was not intended for workstations and was discontinued by HP in 1998 and obsoleted in 1999.

HP-UX 10.20 supported most 32-bit HP 9000 models, Hardware Enhancements bundles (HWE) were shipped (ACEs) to support newer PA-8x00 based systems in 32-bit. Most HP 9000 graphics options and HP I/O devices and networking adapters integrated on HP 9000s were supported. Support for PA-RISC 1.0 and older 800 servers from the 80s was dropped.

HP-UX 10.10

HP-UX 10.10 was released in 1996 and apparently a feature-only release with few enhancements to HP-UX 10.00. It was discontinued by HP in 2000 and obsoleted in 2002.

New features and upgrades in HP-UX 10.10 included:

Supported hardware is unclear but probably the same as HP-UX 10.00. HP-UX 10.10 was the last stable OS release for several older Series 800 servers: 840S, 825S, 835S/SE, 845S/SE, 850S, 855S, 860S, 865S, 870S/x00, 822S, 832S, 842S, 852S, 890.

HP-UX 10.00

HP-UX 10.0 (or 10.01) was released in 1995, first as an on-demand New Business Release (NBR) for new HP 9000 hardware acquisitions and automatically shipped as General Business Release (GBR) for existing installations. There were different products for HP-UX 10 on workstations and servers. HP-UX 10.01 was discontinued by HP in 2000 and obsoleted in 2003.

The file system structure in HP-UX 10 was moved to a SVR4 (System V Release 4) layout, which was becoming a UNIX standard. Software and licenses integrated into HP-UX included OSF Distributed Computing Environment (DCE), Streams and XTI over TCP/IP (ARPA/9000), NFS, NCS, X.11, Motif and HP VUE (Visual User Environment). HP-UX 10.0 was binary compatible from HP-UX 9.0. New features and upgrades in HP-UX 10.0 included:

HP-UX 10.0 supported all currently orderable HP 9000 Server and Workstation systems and added support in the General Business Release for more systems case by case.

HP supported HP-UX 9.0 in parallel to 10.0 due to the large installed HP-UX 9 userbase. While HP-UX 10.0 was released, HP supported new workstations and graphics in HP-UX 9.07 and marketed a clear upgrade path. At HP-UX 10.01 discontinuance in 2000, HP recommended directly upgrading to 11.00 (and not 10.20).

HP-UX 10.0 was probably the last HP-UX to support the early HP 9000 800 servers based on PA-RISC 1.0, though it is not totally clear which systems were exactly (still) supported.

HP-UX 9

HP-UX 9 was released between 1992 and 1994 and was a popular and stable version of HP-UX for PA-RISC 1.0 and 1.1 32-bit workstations and servers in the 700 and 800 Series. Again there different releases for workstations and servers in HP-UX 9, like in HP-UX 8 before: 700 Series workstations had odd version numbers, 800 Series servers even versions. From the first release HP-UX 9 included PA-7100 support, POSIX shell, the graphical HP VUE 3.0 environment.

The last HP-UX 9 versions were discontinued in May 1998 and obsoleted, as HP-UX 9 was supposedly not Y2K-ready for the coming change of the century. HP suggested an update to HP-UX 10.20 to ensure proper system operation in the Year 2000. HP-UX 9 was supposedly that last HP Unix that was strongly BSD-based, before switching to System V flavour in 10.x

Most of HP-UX 9 and earlier versions were released prior to the Web-era of HP technical information so definite documentation is a bit hard to come by.

HP-UX 9 for Workstations

HP-UX 9 was the second major release for the PA-RISC workstations and supported most of the HP 9000 Series 700 workstations well. From the first release, it apparently supported the PA-7000 705, 710 and 720, 730, 750.

HP-UX 9.01 was released in 1993 and added hardware support for PA-7100-based 725 and 735, 755 workstations and 742i, 745i and 747i VME boards

Also supported are the PA-RISC upgrade for Motorola 68000-based Models 425s and 425t, 1GB, 2GB, and 525MB SCSI drives, CRX48Z graphics and JIS (Japanese) keyboards.

from archive.org

HP-UX 9.03 was released in 1993 and was required for several newly released HP hardware, including PA-7100LC 712 workstation, floppy-disk support (SCSI?), device drivers for LASI chipset,

Software-wise, HP-UX 9.03 enhanced support for BOOTP and TFTP, smart shutdown, changes to SAM cluster configuration, and reduced the kernel and base OS footprint.

HP-UX 9.05 was released in 1993 9.05 is primarily a hardware release that provides support for the following computers and devices

It added support for the 32-bit PA-7100LC 715 and 725, and the PA-7150 735, 755 workstations. The PA-7100LC VME workstations 743i and 748i are also supported with 9.05. Additional support was added for HCRX graphics, 1GB half-height SCSI and 2GB SCSI drives.

HP-UX 9.07 was also released in 1993 and added hardware support for the PA-7200 J200, J210 and possibly C100, C110 workstations and multi-buffered X11.

HP-UX 9.09 was released in 1994 and probably not widely shipped. It supposedly was a B-level Security release with very strict security controls (mandatory security). These B1 versions were separate products parallel to the other HP-UX 9 releases.

HP-UX 9 for Series 800

The separate product stream of HP-UX 9 started with version 9.00 in 1992 which included support for the new PA-7100 servers. For the HP-UX 9 server version only very sparse information remains.

HP-UX 9.00 was released in July 1992 and added support for PA-7100 processors, a POSIX shell, VUE 3.0, fastlinks and ioscan(1) and model(1) commands plus the Logical Volume Manager (LVM) for disk management.

HP-UX 9.02 was released in 1993 and added hardware support.

HP-UX 9.04 was released in November 1993 and discontinued by HP in 1997 and obsoleted at the end 1998. It also added hardware support.

HP-UX 9.06 was supposedly released in 1994 but it is not clear if it was a released product or internal version (plan).

HP-UX 9.08 was released in 1994 and probably not widely shipped. It supposedly was a B-level Security release with very strict security controls (mandatory security). These B1 versions were separate products parallel to the other HP-UX 9 releases.

HP-UX 8

HP-UX 8 was the HP Unix for the new 32-bit PA-7000 and PA-7100 computers, released in 1991. The codebases for 700s workstations and 800s servers were different in HP-UX 8 with separate releases for workstations (odd version numbers) and servers (even versions). HP-UX 8 was the first HP-UX to support SMP multiprocessing in the server versions starting with HP-UX 8.06.

HP-UX 8 for Workstations

In 1991 and 1992, the first true HP 9000 700 workstations based on PA-RISC 1.1 PA-7000 CPUs were released. HP-UX 8 was the first support for these workstations and architecture.

HP-UX 8.01 was released in 1991 and only sold to developers to create/test programs. It supported the HP 9000 720, 730 and 750 workstations, with other hardware support unclear.

HP-UX 8.05 was released in July 1991, a partial release, not considered complete and documented as interim at the time of shipments. Supported systems again included the HP 9000 720, 730 and 750 workstation systems.

HP-UX 8.07 was released in January 1992 as the final 8.0 release for workstations and supported the new HP 9000 705, 710 as well as the 720, 730 and 750 systems. Hardware support was added for CRX, CRX-24, Dual-CRX, CD-ROM, 2.0GB drives, EISA cards (X.25, 802.5, FDDI), DDS tape drives. Software support was added for AAPI audio API

There might have been a Trusted Systems HP-UX 8.09 version with B1 mandatory security.

HP-UX 8 for Servers

HP-UX 8 supported many of the original PA-RISC server systems in the HP 9000 800 series.

HP-UX 8.00 was released in January 1991. Not much more information is findable these days other than it supporting some (most?) of the older HP 9000 800 servers such as 825, 855 et al.

HP-UX 8.02 was released in April 1992 and was rewritten to work on the new, lettered HP 9000 800 Nova servers – the F, G, H and I-Class (8x7).

HP-UX 8.06 was released in 1992 and is a HP-UX 8.0 with additional code to handle multiple processors of the HP 9000 870 with up to four PCX processors.

HP-UX 8.04 and HP-UX 8.08 were released in 1991 and 1992 and were described as security versions of 8.0 without additional hardware or software support.

Older HP-UX

There were even older versions of HP-UX Unix released between 1984 and 1990 for the various product families shipped by HP during that time. Releases were often architecture-specific and numbering was not very coherent – for example HP-UX 3.0 for PA-RISC was released in parallel to HP-UX 6.0 for Motorola 68000. This was apparently unified with HP-UX 7 or HP-UX 8.

HP-UX 7

HP-UX versions 7 were released from 1989 to 1990, mostly for Motorola 68000 systems. Apparently, HP-UX 7.03 supported PA-RISC systems in some way, probably the 800 Series servers. There is not much verifiable information on this though.

HP-UX 3

HP-UX 3.0 was released in 1988, in parallel to the 68000-specific HP-UX 6.0, it supported (apparently) at least the HP 9000 825, 835 and 850. The 3.x versions of HP-UX were apparently PA-RISC-only releases for early 800/600 Series servers.

Sources from 1989 mention several nasty bugs in an HP-UX 3.01 release on the 850 server. It also supported an HP-implementation of X11.

HP-UX 2

HP-UX 2, released in 1987, was either the first or second release for the PA-RISC Series 800 servers. It apparently supported the first HP 9000 840 and other early HP 9000 825, 835 and 850 servers. There were at least HP-UX 2.0 and HP-UX 2.1 releases for these PA-RISC 1.0 systems, strongly BSD-influenced. They also supported the workstation 825 and 835 with graphics hardware — when the server 800s were marketed as 635SV and 645SV for a (confusing) time.

HP-UX 1

Some sources mention a HP-UX 1.0 as being the first HP-UX for PA-RISC HP 9000 840, released in 1986. This HP-UX was supposedly strongly BSD-based, in contrast to the AT&T HP-UX 1.0 for Series 500. Since versioning and naming was in flux during that time, maybe it was a pre-release of the product that became HP-UX 2.0, bundled with first 840 servers.

Other HP-UX

The first HP-UX 1.0 was released in 1983 for the HP FOCUS and was supposedly very different to other HP-UX versions, based on an AT&T kernel. There was another HP-UX 1.0 in 1984 for the HP Integral PC (on ROM) before the 1.0 for PA-RISC in 1986.

HP-UX 5.0 was released in 1985 and supported the Motorola-based Series 200 and 300 as well as the FOCUS HP 9000 500, for which it was the last supported HP-UX (5.3). HP-UX for the FOCUS 500 Series was the first commercial UNIX supporting a multi-processor, multi-user system in the early 1980s. SMP for PA-RISC was supported only much later in HP-UX.

HP-UX 6.0 from 1986 was for Motorola 68000 systems, before unifying with PA-RISC in 7.0.

References

Most of the documentation and references disappeared during the 2010s from the web. Much information has been gleaned from (slowly disappearing) USEnet postings from the 1980s and early 1990s in comp.sys.hp.hpux, especially for older versions of HP-UX.
