Adding a new disk and mount it automatically.
Step-1 Add virtual disk to vmware server.
=========================================
Step-2 Bounce the box
=========================================
Step-3 Make sure the new hard drive should be identified by your linux box.
=========================================
As following example, you can see I added /dev/sdc worth of 20GB.
[root@oem ~]# fdisk -l
Disk /dev/sda: 10.7 GB, 10737418240 bytes
255 heads, 63 sectors/track, 1305 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes
Device Boot Start End Blocks Id System
/dev/sda1 * 1 19 152586 83 Linux
/dev/sda2 20 1305 10329795 8e Linux LVM
Disk /dev/sdb: 21.4 GB, 21474836480 bytes
255 heads, 63 sectors/track, 2610 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes
Device Boot Start End Blocks Id System
/dev/sdb1 1 2610 20964793+ 83 Linux
Disk /dev/sdc: 21.4 GB, 21474836480 bytes
255 heads, 63 sectors/track, 2610 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes
Disk /dev/sdc doesn’t contain a valid partition table
Step-4 Create the partition as following.
=========================================
[root@oem ~]# fdisk /dev/sdc
Device contains neither a valid DOS partition table, nor Sun, SGI or OSF disklab el
Building a new DOS disklabel. Changes will remain in memory only,
until you decide to write them. After that, of course, the previous
content won’t be recoverable.
The number of cylinders for this disk is set to 2610.
There is nothing wrong with that, but this is larger than 1024,
and could in certain setups cause problems with:
1) software that runs at boot time (e.g., old versions of LILO)
2) booting and partitioning software from other OSs
(e.g., DOS FDISK, OS/2 FDISK)

[root@oem ~]#
Step-5 Validate the partition as following:
===========================================
In following information, you are seeing /dev/sdc1, this is the new partition that I created just now.
[root@oem ~]# fdisk -l
Disk /dev/sda: 10.7 GB, 10737418240 bytes
255 heads, 63 sectors/track, 1305 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes
Device Boot Start End Blocks Id System
/dev/sda1 * 1 19 152586 83 Linux
/dev/sda2 20 1305 10329795 8e Linux LVM
Disk /dev/sdb: 21.4 GB, 21474836480 bytes
255 heads, 63 sectors/track, 2610 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes
Device Boot Start End Blocks Id System
/dev/sdb1 1 2610 20964793+ 83 Linux
Disk /dev/sdc: 21.4 GB, 21474836480 bytes
255 heads, 63 sectors/track, 2610 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes
Device Boot Start End Blocks Id System
/dev/sdc1 1 2610 20964793+ 83 Linux
[root@oem ~]#
Step-6 Create ext3 file system as following.
=====================================================
[root@oem ~]# mke2fs -j /dev/sdc1
mke2fs 1.39 (29-May-2006)
Filesystem label=
OS type: Linux
Block size=4096 (log=2)
Fragment size=4096 (log=2)
2621440 inodes, 5241198 blocks
262059 blocks (5.00%) reserved for the super user
First data block=0
Maximum filesystem blocks=4294967296
160 block groups
32768 blocks per group, 32768 fragments per group
16384 inodes per group
Superblock backups stored on blocks:
32768, 98304, 163840, 229376, 294912, 819200, 884736, 1605632, 2654208,
4096000
Writing inode tables: done
Creating journal (32768 blocks): done
Writing superblocks and filesystem accounting information: done
This filesystem will be automatically checked every 27 mounts or
180 days, whichever comes first. Use tune2fs -c or -i to override.
[root@oem ~]#
Step-7 Create the mount folder.
==================================================
[root@oem ~]#
[root@oem ~]# cd /
[root@oem /]# mkdir u02
[root@oem /]# ls -rlt /u02
total 0
[root@oem /]#
Step-8 Mount the file system to /u02 manually for test
======================================================
[root@oem /]# mount /dev/sdc1 /u02
[root@oem /]# df -k /u02
Filesystem 1K-blocks Used Available Use% Mounted on
/dev/sdc1 20635700 176200 19411264 1% /u02
[root@oem /]#
[root@oem /]# df -k
Filesystem 1K-blocks Used Available Use% Mounted on
/dev/mapper/VolGroup00-LogVol00
7935392 5385392 2140400 72% /
/dev/sda1 147764 12189 127946 9% /boot
tmpfs 601112 0 601112 0% /dev/shm
/dev/sdb1 20635700 18561860 1025604 95% /u01
/dev/sdc1 20635700 176200 19411264 1% /u02
[root@oem /]#
Step-9 Mount the filesystem automatically, when your Linux starts
=================================================================
Put following entry in /etc/fstab
/dev/sdc1 /u02 ext3 rw 0 0
Step-10 Validate whether automount is working or not by bouncing the instance.
