Partitioning a SCSI device
You can partition SCSI devices that are attached through an FCP channel in the same way that you can partition SCSI attached devices on other platforms.
About this task
Use the fdisk command to partition a SCSI disk, not fdasd.
udev creates device nodes for partitions automatically. For the SCSI disk /dev/sda, the partition device nodes are called /dev/sda1, /dev/sda2, /dev/sda3, and so on.
Example
To partition a SCSI disk with a device node /dev/sda issue:
# fdisk /dev/sda
