HP-UX 10.20 System Requirements

Besides the minimums shown below, you will have additional requirements for such things as swap space, tools, utilities, facilities, environments, applications, languages, user files, data, graphics, printing and plotting. Refer to the System Administration Tasks manual for information on these topics.

Hardware Requirements

To install HP-UX 10.20 you must have:

Title not available (Hardware Requirements )

Computer

An HP 9000 Server (Series 800) computer. This release provides specific support for Models A180 and A180C, but also supports a number of earlier Server models.

Memory

The minimum RAM for HP-UX 10.20 is 32 MB. (For some older Series 800 models, such as 8x5 which support 8 MB cards in the first slot, the RAM requirement for system loading must be configured as at least 16 MB in the first slot.) Your HP representative can assist in obtaining the proper amount of RAM. Some guidance on RAM requirements is also on the following web site: www.hp.com/esy/systems_networking/systems/services/upgrade_guidelines.html.

Source Device

Make sure that your system has an appropriate source (CD-ROM, DDS drive, or network). For tape drives, be sure the heads are clean.

Disk Drive

At least one hard-disk drive with at least the following capacities: (The install program performs an analysis of disk space needed prior to loading the software.)

1 GB or more for a general usage server system.

Other Devices

Your system can also have any HP-supported device. If you have an unsupported device connected to your system, HP assumes no responsibility in making that device function properly.

Supported Peripherals

With the disk space provision above, all disk drives that are supported as Series 700 and 800 system disks are supported for installation.

Disk arrays can be installed with HP-UX, but the installation tasks do not support configuring an array. See your array documentation for configuration information.

The HP-UX installation tools support VT100 and Wyse 60 terminals, compatible emulations, and all HP terminals.

Supported File System Types and Layouts

The HP-UX 10.20 file system layout is quite different from HP-UX 9.0xreleases. The 10.20 file system is modeled after the UNIX™ SVR4 and OSF/1 systems. This layout provides such benefits as the separation of OS software from application software, and it also resembles the UNIX standard layout used by many other computer companies.

File System Types

HP-UX 10.20 supports the following file system types:

UFS/HFS or VxFS (Journaled File System) on local disk volumes.
NFS.

Disk Layouts

The file system for a cold-installed HP-UX will be supported on the following disk layouts:

"Whole disk" (single file system, single swap partition disk layouts as on HP-UX 9.0 for Series 700).
The Logical Volume Manager (LVM).

The Logical Volume Manager is offered on both the Series 700 and Series 800 platforms. Because it helps to organize file space across multiple physical disks, you are encouraged to adopt this method of disk management. See the manual System Administration Tasks, or the lvm(7) man page for details.

For HP-UX 10.20, Series 700, Software Disk Striping arrays are not supported. SDS arrays can be converted to LVM via the utility sdstolvm. If you upgrade to HP-UX 10.20, as opposed to installing it, this conversion will be done for you automatically during the upgrade.

LVM disk striping can be set up on some volumes during the installation. However, striped volumes cannot be mirrored later on. Note that not all types of volumes may be striped. This is due to an unbalanced amount of disk space assigned to the root/boot/swap volumes on the root disk that must not be striped.

Networking Requirements

Networking capabilities are not mandatory for a 10.20 cold install unless you are loading your OS and applications from a remote system. If you are loading from a remote system, you will need the following (for the Ethernet™ interface):

A network card. If your system has multiple LAN cards, select the card that is configured onto the correct network during the install process. Only one card can be configured for install. All other cards will not be configured and cannot be used during the installation.
A network install server. This must be on the same network subnet as the system that will be booted. This may require having one server on each subnet from which to boot clients.
A functional network connection. If you have more than one LAN connection, be prepared to select the correct one with which to connect to the install server system.

Note: You cannot cold install via the network from a non-Ethernet interface.
