Hi, what is concept of core in ibm platform? I want to know how to find out no of core in cpu in aix i. Wheather any specification is there? Each physical processor may support multiple virtual processors.

Each virtual processor is an entity with its own interrupt ID, capable of executing independent threads. Displays 1 if the specified processor is fully on-line. Displays 0 if the specified processor is non-inter- ruptible, spare, off-line, faulted or powered off. Use silent mode when using psrinfo in shell scripts. When combined with the -v option, reports additional information about each physical processor. Displays additional information about the specified processors, including: processor type, floating point unit type and clock speed.

If any of this information cannot be determined, psrinfo displays unknown. When combined with the -p option, reports additional information about each physical processor.

Allows you to relocate logically or physically a disk device to a new hardware location without having to change its device special file.

HP-UX 11i version 3 expands your ability to replace hardware components on a running instance of HP-UX without having to shut down or reboot. There are also other important considerations when adding and removing PCI cards. When an HP-UX system panic crash occurs, a memory dump is usually written to disk so that, if necessary, an analysis can be done to determine what caused the crash. On servers with very large amounts of memory, the process of writing memory contents to disk can take a very long time.

If you have multiple devices configured for memory dump, HP-UX can be configured to split the task of dumping memory and write to the devices in parallel. New Processor Terminology. Server Nomenclature. PCI Cards. Longer User and Group Names. With STM version C. You must boot the nPartition into nPars mode to operate these utilities. For example, if you have three virtual partitions, each with one bound CPU, and two unbound CPUs not assigned to any of the partitions, this is a total of five CPUs in the server.

The data on unbound CPUs is repeated for each virtual partition. Therefore, adding up the numbers results in a total of nine CPUs for the server when there are actually only five physical CPUs.

Ignite-UX version B. For example, the tape cannot be used with the vparboot -I command. Ignite-UX and other Curses Applications On the virtual console, when using applications that use curses, such as the terminal versions of Ignite-UX and SAM, do not press Ctrl-A to toggle to the console display window of another virtual partition while you are still within the curses application.

This is especially applicable when you are using vparboot -I and the Ignite-UX application to install vPars. As with most curses applications, if you get a garbled display, you can press Ctrl-L to refresh the display. ServiceGuard ServiceGuard is supported with vPars. However, because ServiceGuard is used to guard against hardware failures as well as software failures, its functionality will be reduced if a cluster includes multiple virtual partitions within the same server.

Such configurations are not recommended. By default, a hard partition has only one serial port. For a hard partition that runs vPars, the serial port can be owned by at most one virtual partition.

Therefore, on the hard partition, the UPS can communicate with only the virtual partition that owns the serial port. Processor Sets vPars A. Therefore, to avoid unintentionally removing unbound CPUs from a non-default pset, initially create the partition that will be running Processor Sets using only bound CPUs. The vPars Monitor keeps track of the OS time for each virtual partition relative to the real-time clock.

If you change the real-time clock, you need to run the vPars Monitor command toddriftreset to reset the drifts relative to the real-time clock.

If the machine is then booted into a vPars environment, the OS time of all the virtual partitions will be advanced. Administrators should ensure that the RTC is adjusted accordingly before booting the machine from standalone mode into a vPars environment and vice versa. For more information, see the vparutil 1M manpage. For vPars A. System-wide stable storage and the setboot command On a non-vPars server, the setboot command allows you to read from and write to the system-wide stable storage of non-volatile memory.
