17.12.1. FCP Devices
FCP
(
Fibre Channel protocol
) devices enable IBM System z to use SCSI devices rather than DASD
devices.
FCP
(
Fibre Channel protocol
) devices provide a switched fabric topology that enables zSeries
systems to use SCSI LUNs as disk devices in addition to traditional DASD devices.
Typically, an operating system is loaded, and the automatic probing and defining of hardware is done
by the OS. However, because of the flexibility of configurations associated with FCP, IBM System z
requires that any FCP (Fibre Channel protocol) device be entered manually (either in the installation
program interactively, or specified as unique parameter entries in the CMS conf file) in order for the
installation program to recognize the hardware. The values entered here are unique to each site in
which they are setup.
Note
Interactive creation of a zFCP device is only possible in the graphical mode installer. It is
not possible to interactively configure a zFCP device in a text-only install.
Each value entered should be verified as correct, as any mistakes made may cause the system not to
operate properly.
For more information on these values, refer to the hardware documentation that came with your
system and check with the system administrator who has setup the network for this system.
