Q. How do I get detailed information about my Linux server hardware information?
A. You need to use tool called lshw to extract detailed information on the hardware configuration of the machine. It can report exact memory configuration, firmware version, main board configuration, CPU version and speed, cache configuration, bus speed, etc. on DMI-capable x86 or IA-64 systems and on some PowerPC machines.
It currently supports DMI (x86 and IA-64 only), OpenFirmware device tree (PowerPC only), PCI/AGP, CPUID (x86), IDE/ATA/ATAPI, PCMCIA (only tested on x86), SCSI and USB.
List hardware
Type the lshw at a shell prompt:
$ lshw

Similar result can be produced with command ‘dmidecode’. But the output is not so nicely formated as with lshw. :)
Is this same as lshal .. I am using that and I couldn’t find lshw

lshw is a different command I believe. You need to have the dag repositories installed on the server to have this pre-enabled. If not then you can get the lshw command installed. You can get that at the following link:-

another server is configered by 16 gb of RAM, its also show in bios but in linux 5.0 ent. its show only 4 gb. what its problem and how can i solve it.

If you are running 32bit, you will have to have “bigmem” enabled (possibly with the PAE extension?) in the kernel. I don’t know if CentOS provides this kernel or not. If not, you will have to roll your own.
If you are running 64bit, then it should detect all 16GB of memory. If it isn’t then you have a much bigger problem.
As for the SCSI tape drive, afraid I don’t have an answer without knowing a lot more about your setup. Maybe someone else will.
If you are indeed running CentOS try posting to the CentOS forum/mailing list.
Have fun!

I have used these command on centos/RHEL
lspci ( lists pci device)
lsusb ( lists usb device)
lsscsi ( lists scsi device)
systool
fdisk -l ( lists hard drive)
dmidecode ( lists hardware model, serial number, cpu, memory. This command was handy when i needed to find serial number without a visit to data center)
cat /proc/cpuinfo ( more on cpu)
cat /proc/meminfo ( more on memory)
you can find a lot of information by using dmesg|more or grep what you are looking
e.g.
dmesg | egrep ‘(SCSI|scsi0|ide0|hda|sda|serio|mice|eth0|eth1)’

How to get the hardware configuration in linux (debian )
try dmidecode commands it gives all h/w information
second to Sajeevan K. then “pipe it to more: | more” since you will get a lot of info and depending on your putty session buffer you won’t be able to scroll all the way up.
Its really worthful information. I thankful and appreciate all the commenters because Everyone wrote some useful comments in their comment
Thanks

Try using lspci |more
or try to use for update through internet using command
update-pciids
This command will update your hardware.
