How to retrive information if HW / OS is 32 or 64 bit?

[Herbert Loevenich]

I would like to capture the information about Hardware architecture
e.g. 9000/800:32/64
and the installed Operating System
e.g. HP-UX:32 B.11.00

The most important information i would like to
retrive the information if it is 32 or 64 bit,
hardware and which OS version has been installed. This information is visible in software distributor, but i would like to get it from command line.

You can use #uname -a command. For more detail refer the man pages of uname .

The following table gives what hardware can officially run what

As far as the command line is concerned:

# getconf KERNEL_BITS (current OS bits)

# getconf HW_CPU_SUPP_BITS (whether your system is capable of running 32 or 64 bit. If it can run both it will answer

32/64

Unfortunately uname -a doesn't give the detailed information.
HP-UX a7server B.11.00 A 9000/800 2007074959 two-user license

I'm looking for 32/64 bit.

Hi Herbert,

Use "model" to find the hardware type.

Use "getconf KERNEL_BITS" to get 32 or 64 bit.

Use "uname -a" to get OS version.

To find out if kernel supports 64bit binaries by issuing
# file /stand/vmunix
# getconf KERNEL_BITS

To find out the processor info:
# ioscan -fnkC processor
# echo "selclass qualifier cpu;infolog" | /usr/sbin/cstm | grep "CPU Module"

processor type:
# model

processor speed:
# echo itick_per_usec/D | adb -k /stand/vmunix /dev/mem

To find out OS details:
# uname -a

[T G Manikandan]

#getconf KERNEL_BITS for the present OS bit

#getconf HW_CPU_SUPP_BITS

#getconf HW_32_64_CAPABLE

Also you can check /etc/.supported_bits to check whether you machine can support 64 bits



Thanks
