Configure I/O Ports

Use this page to configure I/O ports that are connected to selected host attachments.

Introduction

You can change I/O ports to one of the following options: FcAl, FcSf, or FICON. Changes to the configuration of any I/O ports that already have host attachments that are assigned might prevent those hosts from accessing data using those ports.

Note: ESCON is not supported for the DS6000.

FICON: Select this if you plan to connect one or more S/390 hosts using a FICON S/390 channel to the DS6000 either directly or through a FICON switch.
FcSf: Select this if you plan to connect one or more open systems hosts to the DS6000 through a fabric switch, or if you plan to connect one or more S/390 hosts running LINUX on an FCP S/390 channel.
FcAl: Select this if you plan to connect an open systems host directly to the DS6000 without going through a fabric switch.
Unknown: Select this if the type is unknown.

# of Host Attachments

I/O Port Location

The location that provides the physical link. The value of the location code (R1-I3-C2-T1) is a combination of a rack, enclosure, processor card, and port, where the format is R[1 - 2]-I[1 - 8]-C[1 - 6]-T[0 - 3].
