Accessing the storage unit using FCP for a zSeries host
This section lists the high level steps you must take to access the storage unit
using FCP.

Setting up the storage unit for zSeries hosts running Linux
This topic provides instructions for setting up the storage unit for zSeries hosts
running Linux.
You must collect the following software configuration information to prepare a Linux
system for accessing the storage unit through fibre-channel:
v Host name of the server hosting the Linux system
v Device address and CHPID of the FCP port that is attached to the Linux machine
v Worldwide port name (WWPN) of the FCP port on the zSeries
v Fibre-channel port on the storage unit
v WWPN of the fibre-channel port on the storage unit
You can obtain the data from the hardware management console (HMC), the IBM
TotalStorage DS Storage Manager, and the SAN switch. Figure 46 shows examples
of the prerequisite information you must have to run FCP Linux on the zSeries.

To set up the LUNs for use with your Linux system, you first must define the system
to the storage unit. You can do this through the IBM TotalStorage DS Storage
Manager.
Note: These instructions assume that you are familiar with the IBM TotalStorage
