How to create new partition in Linux
Create New partition or new mount point in linux
If you are using vmware workstation then you can add additional disk. I have added disk
Verify the partitions available on the server: fdisk -l

Choose which device you wish to use (such as /dev/sda or /dev/sdb) Run fdisk /dev/sdX (where X is the device you would like to add the partition to) Lets create partition for /dev/sdb device

Type 'n' to create a new partition. Specify where you would like the partition to end and start. You can set the number of MB of the partition instead of the end cylinder. For example: +1000M Type 'p' to view the partition, and type 'w' to save the partition

Format the partition by doing: mkfs -t ext3 /dev/sdb1

Create new directory to mount the partition
1 2 | [root@asm ~]# mkdir /u01[root@asm ~]# |
Mount the directory
1 2 | [root@asm ~]# mount /dev/sdb1 /u01[root@asm ~]# |
Verify if the partition available. Here we can see partition created as /u01

Edit the fstab to mount the directory automatically.
