HP-UX : Hardware Path

Image
Before this, we discuss about how to check model or processor and today we will talk about the hardware path. In HP-UX , after boot process, the kernel assign every hardware to unique HP-UX hardware path, based on where the component is physically installed. The picture below, described each part of 1 hardware path all about. ok, lets go with hands-on. We can check the hardware path using ioscan command, lets say we want to check disk, we execute this # ioscan -fC disk                       // the options C is a "class" and f is a "full" Class     I H/W Path       Driver S/W State   H/W Type     Description ========================================================== ===================== disk      0 0/0/2/0.0.0.0 sdisk   CLAIMED     DEVI...

HP-UX : Server Model and Processor Details.

Image
Today , i will share command to check model and processor in HP-UX. Sometimes, when you attending interview, the interviewer will ask you how to check server model in hpux and how to determine the processor.This command you can execute if you want check the server model: # model ia64 hp server rx2620 ok here, the server model is hp server r2620 with itanium 64 processor family. ok, now, lets check the processor detail for this model. # machinfo CPU info: 1 Intel(R) Itanium 2 processor (1.6 GHz, 3 MB)           400 MT/s bus, CPU version A2 Memory: 4076 MB (3.98 GB) Firmware info:    Firmware revision: 04.29    FP SWA driver revision: 1.18    IPMI is supported on this system.    BMC firmware revision: 4.04 Platform info:    Model:               ...

HW : Itanium The Different

Image
The Itanium processor chip was developed by an HP/Intel partnership to serve as a successor to both the IA32 architecture currently used in most Intel-based servers, and the PA-RISC technology that has been the cornerstone of HP’s HP-UX server and workstation offerings. The Itanium 2 architecture uses a variety of techniques to increase parallelism—the ability to execute multiple instructions during each machine cycle. Parallelism improves performance because it allows multiple instructions to be executed simultaneously. The Itanium architecture is designed to make certain the processor can execute as many instructions per cycle as possible. A key to the high performance of Itanium chips is the design philosophy at the heart of the Itanium processor family, Explicitly Parallel Instruction Computing (EPIC). The EPIC philosophy is a big reason why Itanium processors are different from other 64-bit processors, providing much higher instruction-level parallelism without unaccep...
