7.3.38 FICON link incident reporting

FICON link incident reporting allows an operating system image (without operator
intervention) to register for link incident reports. Table 7-36 lists the minimum support
requirements for this function.

7.3.39 FCP provides increased performance

The FCP LIC is modified to help provide increased I/O operations per second for both small
and large block sizes, and to support 16-Gbps link speeds.
For more information about FCP channel performance, see the performance technical papers
on the z Systems I/O connectivity website at:

7.3.40 N_Port ID Virtualization

N_Port ID Virtualization (NPIV) allows multiple system images (in LPARs or z/VM guests) to
use a single FCP channel as though each were the sole user of the channel. This feature, first
introduced with z9 EC, can be used with earlier FICON features that have been carried
forward from earlier servers.
Table 7-37 lists the minimum support requirements for NPIV.
