Linux configuration specific commands

GerGon — Wed, 20 Jul 2005 10:41:04 GMT

Hi all,

I need to know following information by using commands via command line (text mode not graphical interface):

From question number 2 and up, assume red hat linux, please...

1. I need to know which linux flavor is running, I suppouse that it is red hat?
2. Which linux version?
3. How many cpu the server have?
4. Disk configuration, i.e. raid X?
5. Disk partitions and disk? (hp user it could by like bdf or vgdisplay)
6. How manu memory the server have?

I don't want to use dmseg; and only a specifics command line.., please!!

Thanks a lot..

Kind of a multi part question:

RAID
/bin/cat /proc/mdstat
mdadm -D /dev/md0
mdadm -D /dev/md1
mdadm -D /dev/md2
mdadm -D /dev/md3
mdadm -D /dev/md4

df -h

Are you using LVM, I know lots of LVM questions.

Varitions on the uname command such as uname -a will answer other questions

[root@shalom bin]# uname --help
Usage: uname [OPTION]...
Print certain system information. With no OPTION, same as -s.

-a, --all print all information, in the following order:
-s, --kernel-name print the kernel name
-n, --nodename print the network node hostname
-r, --kernel-release print the kernel release
-v, --kernel-version print the kernel version
-m, --machine print the machine hardware name
-p, --processor print the processor type
-i, --hardware-platform print the hardware platform
-o, --operating-system print the operating system
--help display this help and exit
--version output version information and exit

1. I need to know which linux flavor is running, I suppouse that it is red hat?
cat /etc/issue or /etc/issue.net

2. Which linux version?

cat /proc/version

3. How many cpu the server have?
cat /proc/cpuinfo

4. Disk configuration, i.e. raid X?
cat /proc/mdstat
mdadm â detail â scan

5. Disk partitions and disk? (hp user it could by like bdf or vgdisplay)
fdisk -l
parted
vgdisplay also exists
df

6. How manu memory the server have?
cat /proc/meminfo
free

Thanks for your time, Excuseme, But I'm newbie in linux.

From the next information by executing your commands, I ssume that: the server have 8 cpu's; obviously Red Hat AS 3.

But How many memory, real RAM without swap? It appear have not array disk set???

Really have 8 CPU's?

Thanks

You have 4 CPUs with hyperthreading.
You have a hardware raid and should download array configuration utility for linux (ACU).
you have 14 GB of RAM memory.

Re: Linux configuration specific commands

Ivan Ferreira — Wed, 20 Jul 2005 15:49:15 GMT

You can see that you have 8 CPU but only 4 differents Physical ID's.

You have 14 GB of memory.

Mem: 14538031104

Mem: 14.538.031.104

Re: Linux configuration specific commands

Gopi Sekar — Wed, 20 Jul 2005 22:50:58 GMT

you are having 4 physical cpus (each having HT enabled thus presenting it as 8 logical cpus). You can verify it by the physical_id column in /proc/cpuinfo. you will see that each physical id is mentioned twice.

you have 14 GB RAM memory.

You are having CCISS controller which means that you are having RAID controller. Information regarding type of RAID, version of RAID controller (5i/6i) can be found by /proc/cciss(i am not sure about this directory).
