HP-UX History

Here is some recent releases from Wikipedia:

11.11 (2000)
Also known as 11i, 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, NFS over TCP/IP, Loadable Kernel Modules, dynamic kernel tunable parameters, kernel event Notifications, and protected stacks.
11.20 (2001)
Also known as 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 did provide support for running PA-RISC compiled applications on IA-64 systems, and for Veritas Volume Manager 3.1.
11.22 (2002)
An incremental release of the Itanium version of HP-UX, it was designated 11i v1.6. This version achieved 64-way scalability, MxN threads, added more dynamic kernel tunable parameters, and supported HP's Logical Volume Manager on IA-64. It was built from the 11i v1 source code stream.
11.23 (2003)
The original release of this version was in September 2003 to support the Itanium-based systems. This version is also identified as 11i v2. In September 2004 the OS was updated to provide support for both Itanium and PA-RISC systems. Besides running on IA-64 systems, this release includes support for ccNUMA, web-based kernel and device configuration, IPv6 and a strong random number generation.
11.31 (2007)
This release is also identified as 11i v3. This release supports both PA-RISC and IA-64.[5] It was released on February 15, 2007.[6] Major new features include native multipathing support, a unified file cache, NFS v4, Veritas ClusterFS, multi-volume VxFS, and integrated virtualization. Hyperthreading is supported on Itanium systems with Montecito processors. HP-UX 11i v3 conforms to the The Open Group's UNIX 03 standard.[7]

[Sep 10, 2010] IT Resource Center forums - sudo for HPUX

Jun 3, 2008


My HPUX (11.23) didn't come with sudo on it.
Is there a reliable source, which I can donwload it from?

Ivan Krastev

Go to and search for sudo. ixSudo one of the bundles available as part of the Internet Express package... just select the one for the OS revision you're running.


Download ixSudo - part of Internet Express package -


1. You dowload only the portions of the Internet Express package that you want. If you just want sudo, then just download ixSudo from the Internet Express download page.

2. Configuration is the same. It's still sudo. HP just built it and packaged it. The only slightly weird thing about it that the sudoers file is actually stored in /opt/iexpress/sudo/etc. There is a symlink, /etc/sudoers, that points to it.

[Sep 25, 2006] AlphaServer Users Face Decisions on Hardware

HOUSTON -- Hewlett-Packard will sell its last new AlphaServer system late next month - a plan that has been forcing users of the technology to decide whether to make one last hardware upgrade or move to a new platform.

Martha Roberts, a systems manager at a financial services firm that she asked not be identified, said at the HP Technology Forum last week that her company has opted to stick with AlphaServers for now.

She said the firm recently spent millions of dollars to purchase more than 20 of the systems after determining that it would be more cost-effective to keep running its custom-built applications on the soon-to-be-discontinued hardware and HP's OpenVMS operating system.

The AlphaServer line is also a proven and reliable technology, Roberts added. The systems were originally developed by the former Digital Equipment Corp. and were acquired by HP when it bought Compaq Computer Corp., which had purchased Digital.

HP, which has ported OpenVMS to its Itanium-based Integrity server line, plans to continue supporting the AlphaServer systems at least until 2011, said Dennis Bak, a product planner in the vendor's AlphaServer life-cycle management group.

Roberts said the new Alpha­Servers that her firm bought will be used until the end-of-support date at a minimum and possibly longer. "I've got servers that I'm replacing right now that are 14 years old," she said.

Mike Trimbach, an OpenVMS manager at Computer Sciences Corp. in El Segundo, Calif., runs AlphaServers at a customer site. Trimbach said his client is evaluating whether to upgrade to the latest AlphaServers or switch to the Integrity line. He added that the potential cost of migrating applications will be the deciding issue. "It may be more cost-effective to just go with the last Alpha," Trimbach said.

After the Oct. 27 cutoff date for AlphaServer orders, users may still be able to get surplus systems from HP or some of its resellers, Bak said. But once sales end, availability will become less certain, he added.

Although HP will continue to develop and support OpenVMS on the Integrity line, the same can't be said for Tru64 Unix, an operating system that has consistently been praised by users for its clustering and file management capabilities. Several years ago, HP considered moving Tru64's clustering technology and file system into HP-UX, but the company rejected that idea, in part because doing so would have forced all HP-UX users to upgrade.

Instead, HP has been offering its ServiceGuard fail-over software with HP-UX, along with a file system that was developed by Veritas Software Corp., which is now owned by Symantec Corp.

If a system in a ServiceGuard cluster goes down, its processing workload is shifted to other servers. But each system requires its own copy of HP-UX, which increases management overhead. That isn't the case with clusters based on Tru64, according to HP.

However, HP officials said at last week's conference that over time, they expect corporate users to rely more on virtualization technology than on clustering.
