Before you begin
Read this information before beginning your installation.
Before you begin your installation, print and complete a Configuration worksheet for your
storage system to gather the information that the software setup process requires. The
configuration worksheet is provided in the Data ONTAP Software Setup Guide for your version
of Data ONTAP, which is available on the IBM® N series support website:
www.ibm.com/storage/support/nseries/
If you are configuring a storage system as part of a high-availability configuration, some
information types must be unique for each storage system mode in the configuration, and
some information types must be identical on both storage system nodes. If you have a
high-availability configuration, IBM recommends that you print and complete two copies of
the configuration worksheet, one for each system node.

v Verify that all expansion unit IDs are correct and sequential in the individual loop(s) or
stack(s), as described in “Setting storage expansion unit shelf IDs.”
v Verify that the speed switches are set correctly, if applicable.
Note: SAS storage expansion units, such as EXN3000, EXN3200, and EXN3500, do not
have speed switches.
If this system was configured by manufacturing, there are labels on the outside of the
packaging carton and on the side of the storage expansion unit chassis to indicate which
loop (1-4) and on which node (A or B) that expansion unit should be located. Make certain
the storage expansion units are placed and cabled according to these labels.
Setting storage expansion unit shelf IDs
Use these instructions to set the storage expansion unit shelf IDs.
Setting SAS expansion unit shelf IDs
A unique shelf ID (from 00 to 98) is required for each SAS storage expansion unit in a SAS
stack.
If your storage system has SAS and FC storage expansion units, the shelf IDs do not need to
be unique between the SAS and FC expansion units. (FC expansion unit shelf IDs continue to
be unique within each FC loop. SAS expansion unit shelf IDs continue to be unique to all
other SAS expansion units in the storage system.)

Connecting the system to expansion units
Use the cabling diagrams in this section to connect the N6200 series filer to the expansion
units.
The following cabling diagrams show a common multipath cabling configuration using
optional quad-port SAS adapters (installed in PCI slot 1) SAS ports on your N7x50T series
filer controller nodes. Multipath storage for high availability configurations provides
redundancy for the path from each controller to every storage expansion unit in the
configuration.
“Dual enclosure HA, all protocols (FC and NAS)” on page 17 shows SAS and ACP cabling for
a dual-enclosure HA pair.
For detailed information about cabling N series SAS storage expansion units, such as the
EXN3000, EXN3200, or EXN3500, refer to the IBM System Storage N series Universal SAS and
ACP Cabling Guide. The SAS ports and ACP ports on the SAS storage expansion unit IOMs are
designated by square and circle symbols. All cabling is done in reference to connecting to
either square or circle ports. SAS connectivity does not use the concept of In and Out ports.
Important: If you are connecting to EXN1000, EXN2000 or EXN4000 storage expansion units:
v When using onboard Fibre Channel ports to connect to EXN1000, EXN2000, or EXN4000
storage expansion units, the onboard ports must be set to initiator mode. For more
information, see "Configuring for initiator mode" in the N7x50T Series Hardware and Service
Guide.
v SFPs must be used when connecting fiber cables.
v If you have a MetroCluster configuration, you must connect to EXN1000, EXN2000, or
EXN4000 storage expansion units. SAS storage expansion units are not supported for
N7x50T series MetroCluster configurations.
16
Notes:
1. For SAN systems with quad-port host bus adapters (HBAs), see the Multipath and
Dual-Path Cabling Information document on the IBM N series support website:
www.ibm.com/storage/support/nseries/
2. For required port usage and specifications for optional adapter cards supported by your
N7x50T series system, refer to the IBM System Storage N Series Introduction and Planning
Guide.
Dual enclosure HA, all protocols (FC and NAS)
The following instructions provide an example for cabling a dual-enclosure HA pair.
The following steps show an overview of the cabling of a N7x50T series dual-enclosure HA

Installing the power cables
Use these instructions to install the power cables for the N7x50T series filer.
1. Make sure all power supply switches on the N7x50T series filer and any attached
expansion units are in the Off position.
2. For all storage systems that are being installed, connect the power cords to all power
supply unit (PSU1 and PSU2) power receptacles using power cord retainer clips as shown
below, making sure to slide the clip all the way forward on the plug.
3. Connect the power cords to the power sources, making sure that the two power supplies
are connected to separate AC sources. This ensures redundant power.
Attention: Do not power on the system at this time.

n620024
Note: The N7x50T series storage system has no requirement or provision for grounding.
For proper grounding of expansion units, see the Installation and Setup Instructions for the
expansion unit.
Setting up and booting the system
Use these instructions to set up and boot the N7x50T series filer.
1. Make sure the Configuration worksheet from the Data ONTAP Software Setup Guide for
7-Mode is completed and available for use.
Note: IBM recommends that you print a copy of this worksheet from the Data ONTAP
Software Setup Guide for 7-Mode.
2. Check that your system is properly set up. Make sure that the expansion unit IDs and
speed switches are properly set, and that the cabling is correct for your configuration.
3. Start a console session for each controller module.
Installation and setup instructions
21
4. Turn on the power to only the expansion units, making sure you turn them on within 5
minutes of each other.
5. After you have powered on the storage expansion units, turn on the N7x50T series filer
controller modules.
Note: It takes the LEDs on the system power supplies a few seconds to illuminate.
The system begins to boot, and then it stops at the first installation question, which is
displayed on the console window.
6. Use the console interface to answer the setup questions for each controller module in
your system. Use the data you collected with the Configuration worksheet.
7. After you complete the setup, check the licenses on the N7x50T series controller modules
by entering the following command:
license
Add any missing licenses by entering the following command for each missing license:
license add <license_code>
where <license_code> is the license code for the product.
Note: Clustering must be licensed on both nodes in an N7x50T series HA pair.
8. Reboot the nodes by entering the following command:
reboot
9. Enable clustering by entering the following command on one node's console:
cf enable
10. Check each node's status by entering the following command:
cf status
Initial setup is now complete for a high availability N7x50T series filer.
Refer to the Data ONTAP 7-Mode High Availability and MetroCluster Configuration Guide for
7-Mode to verify that the system is set up correctly and ready to operate.
11. IBM recommends that you enable AutoSupport and then use the AutoSupport feature to
view the health of the system.

Appendix. Troubleshooting and additional resources
In this section you can find troubleshooting tips and a list of additional resources for the
N7x50T series filer.
Troubleshooting tips
Use these instructions if your N7x50T series system does not boot when you power it on.
Follow these troubleshooting tips in the order shown here.
1. Look for a description on the console. Follow the instructions, if provided, on the console.
2. Check all cables and connections, making sure that they are secure.
3. Ensure that power is supplied and is reaching your system from the power source.
4. Check the power supplies on your system and attached storage expansion units. If the
LEDs on a power supply are not illuminated, remove the power supply and reinstall it,
making sure that it connects with the backplane.
5. Verify disk compatibility and check the disk shelf IDs for your storage expansion units:
v For Fibre Channel storage expansion units:
Within each loop, the storage expansion unit with disk shelf ID 1 must be directly
connected to your system. All other storage expansion units within each loop must have
unique IDs (between 2 and 7) and must be placed in consecutive order.
v For SAS storage expansion units:
All storage expansion units must have unique shelf IDs between 00 and 98.
For more information about shelf ID requirements, see the Hardware and Service Guide for
your N series IBM N series storage expansion unit.
6. Ensure that the storage expansion unit speeds are set correctly:
v EXN1000, set to 2 Gb
v EXN4000, set to 4 Gb or 2 Gb, as necessary
Note: SAS storage expansion units do not have speed switches.
7. Turn off your system and storage expansion units, and then turn on the storage expansion
units. Check the Hardware and Service Guide for your N series storage expansion units for
information about LED responses.
8. Use the system-level diagnostics to check the disks. For more information, see the IBM
System Storage N series System-Level Diagnostics Guide.
9. If your system does not boot successfully, it might not have the boot image downloaded
on the boot device. Call IBM Service and Support at 1-800-IBM-SERV (1-800-426-7378).
