Partitioning the Storwize V3700 system disk
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. Figure 1 shows an example of the different options for the fdisk utility.
