Command to find the harddisk information
I tried to find the harddisk information using the command hdparm -i /dev/sda. But I couldn't get the info. Is there any similar command to find the harddisk serial number.

The uppercase -I switch yields much more information:

Code:
hdparm -I /dev/sda | awk '/Serial Number/{print $1" "$2" "$3}'

The below error message I got.

Code:
hdparm -I /dev/sda | awk '/Serial Number/{print $1" "$2" "$3}'
 HDIO_DRIVE_CMD(identify) failed: Invalid argument

Also, I tried to install the sdparm though its a scsi disk and got the below output with no clue.
l] or <start_byte>:<start_bit>:<num_bits>[=val].
Code:
[root@smasitappl001 /]# sdparm -i /dev/sda
    /dev/sda: IBM  ServeRAID M5014  2.12

Usually you have to use something specific from the RAID manufacturer to see through the RAID to the individual drives. For example: Installing ServeRAID Manager

You can also get some information from /sys in linux:

Code:
$ cat /sys/class/block/sda/device/model
ST3160812AS

$

That may not include the serial number however.

I have a different /sys hierarchy than Corona688 and I see no serial number in /sys. I can get the serial with the hdparm command though.
Code:
#
# cat /sys/block/sda/device/model
WDC WD800JD-75MS
# hdparm -I /dev/sda | awk '/Serial Number/{print $1" "$2" "$3}'
Serial Number: WD-WMAM9TM63898
