Partitioning Devices

After the device parameters have been changed, you can set the partitions. In a Red Hat
®
Linux environment, one LU can be divided into a maximum of four primary partitions.
Instead of primary partitions, you can make a maximum of one extended partition.
To partition the devices:
1. Type fdisk/dev/<device_name> (for example, fdisk/dev/sda, where sda is the
device name).
1. Select p to display the present partitions.
2. Select n to make a new partition. You can make up to four primary partitions, or as an
alternative, 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.
3. Select w to write the partition information to disk and complete the fdisk command.
4. Other commands that you might want to use include:
– To remove partitions, select d.
– To stop a change, select q.
5. Repeat the above steps for each device.
