Partitioning the devices
In a Linux environment, one LUN can be divided into a maximum of four primary partitions (using
fdisk
) or maximum of one extended partition.
After the device parameters have been set, the next step is to set the partitions. To partition the
devices:
1.
Enter
fdisk/dev/
device_name
.
Example
# fdisk/dev/sda
2.
Select
p
to display the present partitions.
3.
Select
n
to make a new partition. You can make up to four primary partitions or you can make
one extended partition. The extended partition can be divided into a maximum of 11 logical
partitions, which can be assigned partition numbers from 5 to 15.
4.
Select
w
to write the partition information to disk and complete the
fdisk
command.
5.
Other commands that you might want to use include:
d
to remove partitions
q
to stop a change
6.
Repeat steps 1–5 for each device.
Creating the file systems
The supported file system for Linux is
ext2
