Attention: Make sure that all storage expansion unit 1Gb/2Gb(/4Gb) switches
are set to the 2Gb or 4Gb, if supported, position. If necessary, refer to the
documents that came with the storage expansion unit for information about
checking and changing the switch setting.
For information that describes how to connect your N7000 series filer to storage
expansion units using the onboard Fibre Channel ports, see the Installation and
Setup Instructions that came with your system.
Attention: If you are using optional adapter cards instead of the onboard Fibre
Channel ports to connect your filer to storage expansion units, see the cabling
instructions described in "Cabling your system using a Fibre Channel expansion
adapter."
Attention: Dual-path Fibre Channel cabling is supported for the N7000 series
filers. Dual-path 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 cabling, see
the Installation and Setup Instructions that came with your system.
Cabling your system using a Fibre Channel expansion adapter
This section describes how to cable your filer storage system using a dual-port
optical Fibre Channel expansion adapter for storage expansion unit (disk shelf)
storage.
Attention: If you are connecting to a stack or stacks of SAS storage expansion
units, such as the EXN3000 or EXN3500, refer to the cabling instructions provided
in the IBM System Storage Universal SAS and ACP Cabling Guide.
This section describes the following tasks:
v "Cabling a single storage system controller"
v "Cabling an active/active or high availability pair" on page 12
For more information about the adapter cards supported by your N7000 series
system, see the appropriate "Optional adapter cards" appendix in the IBM System
Storage N series Introduction and Planning Guide. This guide, as well as Data ONTAP
documentation, is available on the IBM N series support website, which is accessed
and navigated as described in "Websites" on page xx.
Important: If you are not using the onboard ports for storage, then you must set
your onboard ports to Target mode, as described in the Data ONTAP Block Access
Management Guide for your version of Data ONTAP.
Note: The illustrations in the following sections show storage system connections
to EXN2000 or EXN4000 storage expansion units. In EXN1000 storage expansion
units, the positions of the In and Out ports are reversed from those of the
EXN2000 and EXN4000.
