HP-UX 11i (Hewlett Packard Unix) is Hewlett-Packard's proprietary implementation of the Unix operating system, based on System V (initially System III). It runs on the HP 9000 PA-RISC-based range of processors and HP Integrity Intel's Itanium-based systems, and was also available for later Apollo/Domain systems. Earlier versions also ran on the HP 9000 Series 200, 300, and 400 computer systems based on the Motorola 68000 series of processors, as well as the HP 9000 Series 500 computers based on HP's proprietary FOCUS processor architecture.
HP-UX was the first Unix to use access control lists for file access permissions rather than the standard Unix permissions system. HP-UX was also among the first Unix systems to include a built-in logical volume manager. HP has had a long partnership with VERITAS, and they use VxFS as their primary file system. For legacy as well as technical reasons, however, the file system used for the boot kernel remained Hi Performance FileSystem (HPFS; a variant of UFS) until the release of version 11.23 and so this older technology has continued to receive support from HP.
Identifying the Version of the HP-UX Operating System
The internal name for HP-UX 11i is reported by the uname command with the -r option. The external and internal names for the HP-UX 11i operating system are shown here.
.
HP-UX 11i B.11.11
HP-UX 11i v 1.5 B.11.20
HP-UX 11i v 1.6 B.11.22
HP-UX 11i v 2 B.11.23
The current shipping release is HP-UX 11i v3 with Update 3 (0809). HP-UX 11i v3 currently is credited with leadership in observed performance, high availability and manageability.[1] Version 3 of the HP-UX 11i operating system will scale as follows:
128 processor cores
2 TB main memory
32 TB maximum file system
16 TB maximum file size
100 million ZB storage
Key Points
HP-UX operating systems are based on the UNIX operating
system, the HP-UX stems from the System V version which was developed at the University of California at Berkeley. Some basic key points follow:
• The kernel of an HP-UX system is in the /stand directory.
• The file used to resolve hostname to IP under HP-UX is /etc/nsswitch.conf
• HP-UX features a pseudo-swap reservation policy.
• Allow you to tune some kernel parameters.
• The secure ttys database is /etc/securetty for HP-UX
