must be initialized, causing the loss of ALL DATA on this drive."
you may not have a partition table on that drive or the partition table on the drive
may not be recognizable by the partitioning software used in the installation
program.
No matter what type of installation you are performing, backups of the existing
data on your systems should always be made.
12. Advanced Storage Options
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.
