Linux redhat: basic info


I need some help here, Im totally new to linux servers.
I need to know how to get basic info (Redhat Linux, IBM Server :

1) How to know how many hdd is inside the server:
I tried below, but didnt get the info:
[root@em1]# df -kl
Filesystem 1K-blocks Used Available Use% Mounted on
/dev/sda2 302382416 3159664 283862604 2% /
/dev/sda1 178884 13318 156331 8% /boot
none 4117768 0 4117768 0% /dev/shm
51606140 85952 48898748 1% /export/home1
1562102048 108298312 1374453568 8% /export/home2

2) How to get info same as unix "format" command?
3) How to know what raid is the server?
4) How to know whether there are any cold or hot spare configured?
5) How to get the linux version? From uname -a i get kernel version.
6) how to know the application running inside?

more info on hardware or software will be use full.

There are so many books about red hat server administration...why don't you read one.

fdisk -l will show the harddrives/partitions
cat /proc/partitons will show partitions
cat /etc/mtab - mounted partitions
cat /proc/mdstat - if using software raid with mdadm
use lvm tools for volume groups
check bios/controller interface for hardware raid
yum or rpm will help regarding installed software
uname -a shows also the system version
