Viewing the LUNs for zSeries hosts running Linux

This section provides instructions for viewing a list of the LUNs for zSeries hosts that are running Linux.

You must collect the following software configuration information to prepare a Linux system for accessing the storage unit through a fibre channel:

Host name of the server hosting the Linux system
Device address and CHPID of the FCP port that is attached to the Linux machine
Worldwide port name (WWPN) of the FCP port on the zSeries^®
Fibre-channel port on the storage unit
WWPN of the fibre-channel port on the storage unit

You can obtain that information from the hardware management console (HMC), the IBM^® System Storage™ DS Storage Manager, and the SAN switch. Figure 1 shows examples of the prerequisite information that you must obtain to run FCP Linux on the zSeries.

Figure 1. Example of prerequisite information for FCP Linux on zSeries

Linux hostname linuxa
CHPID of the FCP port on the z800 15
WWPN of the FCP port on the z800 50:05:07:64:01:40:01:7d
FC port on the storage unit Enclosure 3 Slot 1
WWPN of the FC port on the storage unit 50:05:07:63:00:c8:95:89

To view the LUNS that aref the volumes assigned to your Linux system, use the IBM System Storage DS Storage Manager.
