I had two hard disk fail on two servers in two week!
They ask me for harddisk serial number.
How to check that in Linux shell?
To see which harddisk I am using:
[root@srv8 home2]# df -h Filesystem Size Used Avail Use% Mounted on /dev/sda6 57G 3.8G 50G 7% / /dev/sda2 251M 29M 210M 12% /boot /dev/sda3 50G 22G 26G 46% /var /dev/sda5 10G 155M 9.3G 2% /tmp /dev/sdc1 1.3T 44G 1.2T 4% /home /dev/sdc2 1.5T 351M 1.4T 1% /home2
So I am using sda and sdc
And how many harddisk do I have:
[root@srv8 ~]# fdisk -lDisk /dev/sda: 128.0 GB, 128035676160 bytes 255 heads, 63 sectors/track, 15566 cylinders Units = cylinders of 16065 * 512 = 8225280 bytes

OK I need the serial number for sdb
[root@srv8 home2]# smartctl -i /dev/sdb -bash: smartctl: command not found
Now I have to install
[root@srv8 home2]# yum install smartctl Loaded plugins: fastestmirror Loading mirror speeds from cached hostfile * base: ftp.plusline.de * extras: ftp.plusline.de * rpmforge: ftp-stud.fht-esslingen.de * updates: ftp.plusline.de Excluding Packages in global exclude list Finished Setting up Install Process No package smartctl available. Nothing to do
That did not work!
OK then
[root@srv8 home2]# whatprovides smartctl -bash: whatprovides: command not found [root@srv8 home2]# [root@srv8 home2]# yum whatprovides smartctl Loaded plugins: fastestmirror Loading mirror speeds from cached hostfile * base: ftp.plusline.de * extras: ftp.plusline.de * rpmforge: ftp-stud.fht-esslingen.de * updates: ftp.plusline.de Excluding Packages in global exclude list Finished Warning: 3.0.x versions of yum would erroneously match against filenames. You can use "*/smartctl" and/or "*bin/smartctl" to get that behaviour No Matches found
hmmm linux is about to never give up!

YES!

And now the magic is working!
