Attention: If you are using optional Fibre Channel adapter cards instead of the
onboard Fibre Channel ports to connect your N6200 series filer to storage
expansion units, see the cabling instructions described in "Cabling an N6200 series
system to Fibre Channel switches using a Fibre Channel expansion adapter."
Dual-path Fibre Channel cabling is supported for N6200 series filers. Dual-path
Fibre Channel cabling is designed to improve reliability, availability and
serviceability of the storage expansion units attached to the storage controller by
creating two redundant paths from each storage controller to each loop of the
storage expansion units. For more information about using dual-path Fibre
Channel cabling, see the Installation and Setup Instructions that came with your
system.
Important: If you are not using the onboard Fibre Channel ports for storage, then
you must set your onboard ports to Target mode, as described in the IBM System
Storage N series Data ONTAP Block Access Management Guide for your version of
Data ONTAP. This guide, as well as other Data ONTAP publications, is available
on the IBM N series support website, which is accessed and navigated as described
in "Websites" on page xxii.
Cabling an N6200 series system to Fibre Channel switches using
a Fibre Channel expansion adapter
About this task
This section describes how to cable an N6200 series system to Fibre Channel
switches using a dual-port optical Fibre Channel expansion adapter for expansion
unit storage. The example shown in this section illustrates the connections for a
single-enclosure HA pair, such as the N6210 2858-C20, N6240 2858-C21, N6270
2858-C22, or N6220 2858-C25.
For a list of optional adapter cards supported by your N6200 series system, refer to
the appropriate "Optional adapter cards" appendix in the IBM System Storage N
series Introduction and Planning Guide. This guide, as well as other N series and
Data ONTAP documentation, is available on the IBM N series support website,
which is accessed and navigated as described in "Websites" on page xxii.
Important: If you are not using the onboard Fibre Channel ports for storage, then
you must set your onboard Fibre Channel ports to Target mode, as described in the
IBM System Storage N series Data ONTAP Block Access Management Guide for your
version of Data ONTAP.
Note: The illustrations in the following sections show connections to EXN4000
storage expansion units. In EXN1000 storage expansion units, the positions of the
In and Out ports are reversed from those of the EXN4000.
