HP-UX Operating System
HP-UX on the V2500/V2600
HP-UX on the V2500/V2600
In general HP-UX administration tasks are performed on V-Class
servers as they are on other HP servers. One difference is that V-Class
servers run the HP-UX kernel only in 64-bit mode. This facilitates
addressing the larger memory capacity available on the V2500/V2600.
However, both 32-bit and 64-bit applications may be run simultaneously
on the server.
Displaying System Information
This section gives brief information on the model, top, and ioscan HP-
UX commands. More HP-UX information is available from the following
Web site.
http://docs.hp.com/
The model command prints the hardware series and model for the
machine it is issued on. On V2500/V2600 servers it displays information
as shown in the command example below.
#
model
9000/800/V2500
For details, see the model(1) man pages.
The top command displays information on the top processes (based on
CPU use) on the system, and lists CPU utilization data for the system’s
processors. Because V-Class servers can have many processors, you may
want to issue top -h when using this command. The -h option
suppresses printing individual lines of processor information, instead
printing only a one-line system average. This makes room on the screen
for showing the active processes running on the system. For more
information, see the top(1) man pages.
Listing the Server Hardware Configuration
The ioscan utility scans the system’s hardware and lists all hardware
found, including processors, memory, I/O devices, and interface cards. On
V-Class servers, ioscan also reports PCI controllers and the core utility
controller and its connections to the Service Support Processor. For more
details, see the ioscan (1M) man pages.
