Partitioning the system disk on the enclosure

Use this information when you set up the system disk partitions.

Before you create a file system, partition the disk by using the fdisk utility. You must specify the special device file of the disk you want to partition when you run fdisk. Example of different options for the fdisk utility shows an example of the different options for the fdisk utility.

Note: If you are using the Subsystem Device Driver (SDD), your path in the example is /dev/vpathb instead of /dev/sdb.

Figure 1. Example of different options for the fdisk utility

# fdisk /dev/sdb

Example of a primary partition on the disk /dev/sdb shows an example of a primary partition on the disk /dev/sdb.

Note: If you are using the SDD, your path in the example is /dev/vpathb instead of /dev/sdb.
