'''HP-UX''' (from "Hewlett Packard Unix") is a [[proprietary software|proprietary]] implementation of the [[Unix]] [[operating system]] developed by [[Hewlett Packard Enterprise]]; current versions support [[HPE Integrity Servers]], based on [[Intel]]'s [[Itanium]] architecture. It is based on [[Unix System V]] (initially [[Unix System III|System III]]) and first released in 1984.

Earlier versions of HP-UX supported the [[HP Integral PC]] and [[HP 9000]] Series 200, 300, and 400 computer systems based on the [[Motorola 68000]] series of processors, the HP 9000 Series 500 computers based on HP's proprietary [[HP FOCUS|FOCUS]] architecture, and later HP 9000 Series models based on HP's [[PA-RISC]] [[instruction set architecture]]. HP-UX was the first Unix to offer [[access-control list]]s for file access permissions as an alternative to the standard Unix permissions system.{{citation needed|date=September 2015}} HP-UX was also among the first Unix systems to include a built-in [[logical volume management|logical volume manager]].{{citation needed|date=September 2015}} 

HP has had a long partnership with [[Veritas Software]], and uses [[Veritas File System|VxFS]] as the primary [[file system]]. It is one of three commercial operating systems that have versions certified to [[The Open Group]]'s [[Single UNIX Specification|UNIX 03 standard]] (the others are [[macOS]] and [[IBM AIX|AIX]]).<ref>{{cite web|url=https://www.opengroup.org/openbrand/register/xy.htm|title=UNIX 03 - The Open Brand Register|access-date=2023-03-22|publisher=[[The Open Group]]}}</ref>

Following the discontinuation of Itanium processors, HP-UX is set to reach [[End-of-life product|end-of-life]] by December 2025.<ref>{{Cite web |last=Sanders |first=James |date=2019-02-01 |title=Save the date: Itanium will finally die at the end of 2025 |url=https://www.techrepublic.com/article/save-the-date-itanium-will-finally-die-at-the-end-of-2025/ |access-date=2024-11-21 |website=TechRepublic |language=en-US}}</ref>

==Characteristics==
{{news release section|date=August 2012}}
HP-UX 11i offers a common shared disks for its clustered file system. [[HP Serviceguard]] is the [[Computer cluster|cluster]] solution for HP-UX. HP Global Workload Management adjusts workloads to optimize performance, and integrates with Instant Capacity on Demand so installed resources can be paid for in 30-minute increments as needed for peak workload demands.

HP-UX offers [[operating system-level virtualization]] features such as hardware partitions, isolated OS virtual partitions on cell-based servers, and [[HP Integrity Virtual Machines]] (HPVM) on all Integrity servers.  HPVM supports guests running on HP-UX 11i v3 hosts&nbsp;– guests can run [[Linux]], [[Windows Server]], [[OpenVMS]] or HP-UX.  HP supports online VM guest migration, where encryption can secure the guest contents during migration.

HP-UX 11i v3 scales as follows (on a SuperDome 2 with 32 Intel Itanium 9560 processors):

* 256 [[Central processing unit|processor cores]]
* 8 [[Terabyte|TB]] main [[Random-access memory|memory]]
* 32 TB maximum [[file system]]
* 16 TB maximum [[Computer file|file]] size
* 128 million [[zettabytes|ZB]]&mdash;16 million [[Logical unit number|logical units]] each up to 8&nbsp;ZB.<ref>{{Cite web|url=https://h20195.www2.hpe.com/v2/GetPDF.aspx/c04111649.pdf|title=QuickSpecs for HP-UX 11i v3|access-date=2019-05-04|website=hpe.com}}</ref>
<!--Interesting history (so I will not delete, just not sure where to move), but in the wrong place, as not according to WP Tru64 is discontinued as of 2012 and its page is unavailable, but TruCluster's page is available, and I'm not sure of its status:
  
With the acquisition of [[Compaq]] in 2001, HP obtained another Unix-based system, [[Tru64 Unix]] for [[AlphaServer]] hardware platform. HP continues to sell Tru64 UNIX, together with [[TruCluster]] software, but discontinued AlphaServer manufacturing in 2007.
-->

==Security==
The 11i v2 release introduced kernel-based [[Intrusion detection system|intrusion detection]], strong [[random number generation]], [[stack buffer overflow]] protection, security partitioning, role-based access management, and various open-source security tools.

HP classifies the operating system's security features into three categories: data, system and identity:<ref>{{cite web|url=http://www8.hp.com/ca/en/products/servers/hp-ux.html?compURI=1473753|title=Protect your environment|access-date=2014-07-22|publisher=[[Hewlett-Packard]]|archive-date=2014-07-27|archive-url=https://web.archive.org/web/20140727042420/http://www8.hp.com/ca/en/products/servers/hp-ux.html?compURI=1473753|url-status=dead}}</ref>

===Context dependent files===
Release 6.x (together with 3.x) introduced the context dependent files (CDF) feature, a method of allowing a [[fileserver]] to serve different configurations and binaries (and even architectures) to different client machines in a heterogeneous environment. A directory containing such files had its [[setuid|suid]] bit set and was made hidden from both ordinary and root processes under normal use. Such a scheme was sometimes exploited by intruders to hide malicious programs or data.<ref>[http://www.selftesttraining.com/hp-certifications.html HP certifications]</ref> CDFs and the CDF filesystem were dropped with release 10.0.

==Supported hardware platforms==
{{Missing information|section|something|date=July 2013}}
HP-UX operating systems supports a variety of [[PA-RISC]] systems. The 11.0 added support for [[HPE Integrity Servers|Integrity]]-based servers for the transition from PA-RISC to [[Itanium]]. HP-UX 11i v1.5 is the first version that supported Itanium. On the introduction of HP-UX 11i v2 the operating system supported both of these architectures.<ref>{{cite web |title=HP-UX 11i compatibility for HPE Integrity and HP 9000 servers |url=https://h20195.www2.hpe.com/V2/GetPDF.aspx/4AA1-1392ENW.pdf |archive-url=https://ghostarchive.org/archive/20221009/https://h20195.www2.hpe.com/V2/GetPDF.aspx/4AA1-1392ENW.pdf |archive-date=2022-10-09 |url-status=live |publisher=Hewlett-Packard |access-date=9 March 2019}}</ref>

===BL series===
HP-UX 11i supports [[HPE Integrity Servers]] of HP BL server blade family. These servers use the Intel [[Itanium]] architecture.

===CX series===
HP-UX 11i v2 and 11i v3 support HP's CX series servers. CX stands for carrier grade and is used mainly for telco industry with -48V DC support and is NEBS certified. Both of these systems contain [[Itanium]] Mad6M processors and are discontinued.

===RX series===
HP-UX supports HP's RX series of servers.{{citation needed|date=February 2018}}

==Release history==
Prior to the release of HP-UX version 11.11, HP used a decimal [[Software versioning|version numbering]] scheme with the first number giving the major release and the number following the decimal showing the minor release. With 11.11, HP made a [[marketing]] decision to name their releases 11''i'' followed by a v(''decimal-number'') for the version. The ''i'' was intended to indicate the OS is [[Internet]]-enabled, but the effective result was a dual version-numbering scheme.

;1.0 (1982): First release for [[HP 9000]] Series 500. HP-UX for Series 500 was substantially different from HP-UX for any other HP machines, as it was layered atop a Series 500 specific operating system called SUNOS (unrelated to [[Sun Microsystems]]' [[SunOS]]).<ref name="wang">{{ cite journal | url=https://archive.org/details/Hewlett-Packard_Journal_Vol._35_No._3_1984-03_Hewlett-Packard/page/n6/mode/1up | title=HP-UX: Implementation of UNIX on the HP 9000 Series 500 Computer Systems | last1=Wang | first1=Scott W.

The exact System III UNIX semantics and syntax are kept, but the HP-UX intrinsics are implemented using SUN kernel support instead of porting the Bell Laboratories kernel implementation to the Series 500. }}</ref>
;1.0 (1984): AT&T System III based. Support for the [[HP Integral PC]] (HP 9807A). The kernel runs from ROM; other commands are disk based.
;2.0 (1984): First release for HP's early [[Motorola 68000]]-based workstations (HP 9816U, HP 9826U, HP 9836U)
;5.0 (1985): AT&T System V based. Distinct versions were available for the Integral PC, the Series 200/300 and the Series 500. Introduced the proprietary ''Starbase'' graphics API for the Series 200, 300 and 500. The Series 300 5.x releases included a proprietary [[windowing system]] built on top of Starbase named ''HP Windows/9000'', which was also available as an optional extra for Series 500 hardware.<ref>{{cite web|url=http://hparchive.com/Catalogs/HP-Catalog-1987.pdf |archive-url=https://ghostarchive.org/archive/20221009/http://hparchive.com/Catalogs/HP-Catalog-1987.pdf |archive-date=2022-10-09 |url-status=live|title=HP Catalog 1987|date=1987|publisher=Hewlett-Packard|access-date=2021-10-26}}</ref>
;3.x (1988): HP 9000 Series 600/800 only. Note: 2.x/3.x (for Series 600/800) were developed in parallel with 5.x/6.x (for Series 200/300/400), so, for example, 3.x was really contemporary with 6.x. The two lines were united at HP-UX 7.x.
;6.x (1988): Support for HP 9000 Series 300 only. Introduced sockets from [[4.3BSD]].  This version (together with 3.x) also introduced the above-discussed context dependent files (CDF), which were removed in release 10 because of their security risks. The 6.2 release added [[X Window System|X11]], superseding HP Windows/9000 and X10.<ref>{{cite web|url=http://vtda.org/docs/computing/HP/UNIX/98592-90000_StarbaseProgrammingWithX11.pdf |archive-url=https://ghostarchive.org/archive/20221009/http://vtda.org/docs/computing/HP/UNIX/98592-90000_StarbaseProgrammingWithX11.pdf |archive-date=2022-10-09 |url-status=live|title=Starbase Programming With X11|date=1988|publisher=Hewlett-Packard|access-date=2021-10-26}}</ref> 6.5 allowed Starbase programs to run alongside X11 programs.

;8.x (January 1991): Support for HP 9000 Series 300/400 600/700/800 systems.<ref name="ADA94"/> Shared libraries introduced. [[Image:HP-UX Install QIC.jpg|thumb|right|HP-UX 9.0 installation software on QIC cartridge, 1992]] 
;9.x (July 1992): 9.00, 9.02, 9.04 (Series 600/800), 9.01, 9.03, 9.05, 9.07 (Series 300/400/700), 9.08, 9.09, 9.09+ (Series 700 only), 9.10 (Series 300/400 only). These provided support for the HP 9000 Series 300, 700 and 800 systems. Introduced [[SAM (HP-UX)|System Administration Manager (SAM)]]. The [[Logical Volume Manager]] (LVM) was presented in 9.00 for the Series 800. Adopted the [[Visual User Environment]] desktop. 
;10.0 (1995): This major release saw a convergence of the operating system between the HP 9000 Series 700 (workstation) and Series 800 (server) systems, dropping support for previous lines. There was also a significant change in the layout in the system files and directories, based on the [[AT&T Corporation|AT&T]] [[SVR4|UNIX System V Release 4]] standard. Applications were removed from /usr and moved under /opt; startup configuration files were placed under /etc/rc.config.d; users were moved to /home from /users. Software for HP-UX was now packaged, shipped, installed, and removed via the [[Software Distributor]] (SD) tools. LVM was also  made available for Series 700.
;10.10 (1996): Introduced the [[Common Desktop Environment]]. UNIX95 compliance.<ref>{{cite web|url=http://www.unixguide.net/hp/faq/3.3.shtml |title=HP-UX FAQ |publisher=unixguide.net |access-date=2019-10-26}}</ref>
;10.20 (1996):{{anchor|10.20 (1996)}} This release included support for 64-bit [[PA-RISC]] 2.0 processors. [[Pluggable Authentication Module]]s (PAM) were introduced for use within [[Common Desktop Environment|CDE]]. The root file system could be configured to use the [[Veritas File System]] (VxFS).

HFS File System|page=8{{hyp}}1|date=August 1992|publisher=[[Hewlett-Packard]]}}</ref> until version 11.23. 10.20 also supported 32-bit user and group identifiers. The prior limit was 60,000, or 16-bit. This and earlier releases of HP-UX are now effectively obsolete, and support by HP ended on June 30, 2003.<ref>{{cite web|url=http://www.hp.com/softwarereleases/releases-media2/latest/aps/1202/intro.htm |title=HP-UX media release |publisher=Hp.com |access-date=2013-01-30}}</ref>
;10.24: This is a ''Virtual Vault'' release of HP-UX, providing enhanced security features.  Virtual Vault is a compartmentalised operating system in which each file is assigned a compartment and processes only have access to files in the appropriate compartment and unlike most other UNIX systems the superuser (or root) does not have complete access to the system without following correct procedures.
;10.30 (1997): This was primarily a developer release with various incremental enhancements. It provided the first support for kernel threads, with a 1:1 thread model (each user thread is bound to one kernel thread).
;11.00 (1997): The first HP-UX release to also support 64-bit addressing. It could still run 32-bit applications on a 64-bit system. It supported [[symmetric multiprocessing]], [[Fibre Channel]], and [[Network File System|NFS]] PV3. It also included tools and documentation to convert 32-bit code to 64-bit.
;11.04: ''Virtual Vault'' release.
;11.10: This was a limited release to support the HP 9000 V2500 SCA (Scalable Computing Architecture) and V2600 SCA servers. It also added JFS 3.3, AutoFS, a new ftpd, and support for up to 128 CPUs. It was not available separately.
;11.11 (2000){{snd}} 11i v1: This release of HP-UX introduced the concept of Operating Environments. It was released in December 2000.  These are bundled groups of layered applications intended for use with a general category of usage. The available types were the Mission Critical, Enterprise, Internet, Technical Computing, and Minimal Technical OEs. (The last two were intended for [[HP 9000]] workstations.) The main enhancements with this release were support for hard partitions, [[Gigabit Ethernet]], [[Network File System|NFS]] over [[Internet protocol suite|TCP/IP]], [[loadable kernel module]]s, dynamic kernel tunable parameters, kernel event Notifications, and protected stacks.
;11.20 (2001){{snd}} 11i v1.5: This release of HP-UX was the first to support the new line of [[Itanium]]-based (IA-64) systems. It was not intended for ''mission critical'' computing environments and did not support HP's ServiceGuard cluster software. It provided support for running PA-RISC compiled applications on Itanium systems, and for [[VERITAS Software|Veritas]] Volume Manager 3.1.
;11.22 (2002){{snd}} 11i v1.6: An incremental release of the [[Itanium]] version of HP-UX. This version achieved 64-way [[scalability]], ''m:n'' [[thread (computing)|threads]], added more dynamic kernel tunable parameters, and supported HP's Logical Volume Manager on Itanium. It was built from the 11i v1 source code stream.
;11.23 (2003){{snd}} 11i v2: The original release of this version was in September 2003 to support the Itanium-based systems. In September 2004 the OS was updated to provide support for both Itanium and PA-RISC systems.  Besides running on Itanium systems, this release includes support for [[ccNUMA]], web-based kernel and device configuration, [[IPv6]], and stronger random number generation.
;11.31 (2007){{snd}} 11i v3: This release supports both PA-RISC and Itanium.<ref>{{cite web | author=Staff | date=2007-03-14 | url=http://h20338.www2.hp.com/hpux11i/downloads/HP-UX_Binary_Compatibility.pdf | title=HP-UX 11i compatibility for HP Integrity and HP 9000 servers | publisher=HP | access-date=2008-07-24 | url-status=dead | archive-url=https://web.archive.org/web/20081024031028/http://h20338.www2.hp.com/hpux11i/downloads/HP-UX_Binary_Compatibility.pdf | archive-date=2008-10-24 }}</ref> It was released on February 15, 2007.<ref>{{cite news
