Safety notices vii

Rack safety

Rack installation

DANGER

Observe the following precautions when working on or around your IT rack system:

v Heavy equipment - personal injury or equipment damage might

result if mishandled.

v Always lower the leveling pads on the rack cabinet.

v Always install stabilizer brackets on the rack cabinet.

v To avoid hazardous conditions due to uneven mechanical

loading, always install the heaviest devices in the bottom of the rack cabinet. Always install servers and optional devices starting from the bottom of the rack cabinet.

v Rack-mounted devices are not to be used as shelves or work

spaces. Do not place objects on top of rack-mounted devices.

(R001 part 1 of 2)

v Each rack cabinet might have more than one power cord. Be

sure to disconnect all power cords in the rack cabinet when directed to disconnect power during servicing.

v Connect all devices installed in a rack cabinet to power devices

installed in the same rack cabinet. Do not plug a power cord from a device installed in one rack cabinet into a power device installed in a different rack cabinet.

v An electrical outlet that is not correctly wired could place

hazardous voltage on the metal parts of the system or the devices that attach to the system. It is the responsibility of the customer to ensure that the outlet is correctly wired and grounded to prevent an electrical shock.

viii IBM System Storage: N6200 Series Hardware and Service Guide

CAUTION:

v Do not install a unit in a rack where the internal rack ambient temperatures

will exceed the manufacturer's recommended ambient temperature for all your rack-mounted devices.

v Do not install a unit in a rack where the air flow is compromised. Ensure that

air flow is not blocked or reduced on any side, front, or back of a unit used for air flow through the unit.

v Consideration should be given to the connection of the equipment to the

supply circuit so that overloading of the circuits does not compromise the supply wiring or overcurrent protection. To provide the correct power connection to a rack, refer to the rating labels located on the equipment in the rack to determine the total power requirement of the supply circuit.

v (For sliding drawers.) Do not pull out or install any drawer or feature if the rack

stabilizer brackets are not attached to the rack. Do not pull out more than one drawer at a time. The rack might become unstable if you pull out more than one drawer at a time.

v (For fixed drawers) This drawer is a fixed drawer and should not be moved for

servicing unless specified by manufacturer. Attempting to move the drawer partially or completely out of the rack may cause the rack to become unstable or cause the drawer to fall out of the rack.

(R001 part 2 of 2)

Safety notices ix

Rack relocation (19" rack)

CAUTION: Removing components from the upper positions in the rack cabinet improves rack stability during relocation. Follow these general guidelines whenever you relocate a populated rack cabinet within a room or building:

v Reduce the weight of the rack cabinet by removing equipment starting at the

top of the rack cabinet. When possible, restore the rack cabinet to the configuration of the rack cabinet as you received it. If this configuration is not known, you must do the following:

– Remove all devices in the 32U position and above.

– Ensure that the heaviest devices are installed in the bottom of the rack

cabinet.

– Ensure that there are no empty U-levels between devices installed in the

rack cabinet below the 32U level.

– If the rack cabinet you are relocating is part of a suite of rack cabinets,

detach the rack cabinet from the suite.

– Inspect the route that you plan to take when moving the rack to eliminate

potential hazards.

– Verify that the route that you choose can support the weight of the loaded

rack cabinet. Refer to the documentation that came with your rack cabinet for the weight of a loaded rack cabinet.

– Verify that all door openings are at least 760 x 2030 mm (30 x 80 in.).

– Ensure that all devices, shelves, drawers, doors, and cables are secure.

– Ensure that the four leveling pads are raised to their highest position.

– Ensure that there is no stabilizer bracket installed on the rack cabinet

during movement.

– Do not use a ramp inclined at more than ten degrees.

– Once the rack cabinet is in the new location, do the following:

- Lower the four leveling pads.

- Install stabilizer brackets on the rack cabinet.

- If you removed any devices from the rack cabinet, repopulate the rack cabinet from the lowest position to the highest position.

– If a long distance relocation is required, restore the rack cabinet to the

configuration of the rack cabinet as you received it. Pack the rack cabinet in the original packaging material, or equivalent. Also, lower the leveling pads to raise the casters off of the pallet and bolt the rack cabinet to the pallet.

(R002)

x IBM System Storage: N6200 Series Hardware and Service Guide

Handling fiber-optic cables

Before you use fiber-optic cables, read the following precautions.

Attention: To avoid damage to the fiber-optic cables, follow these guidelines:

v Do not route the cable along a folding cable-management arm.

v When attaching to a device on slide rails, leave enough slack in the cable so that

it does not bend to a radius of less than 38 mm (1.5 in.) when extended or become pinched when retracted.

v Route the cable away from places where it can be snagged by other devices in

the rack cabinet.

v Do not overtighten the cable straps or bend the cables to a radius of less than 38

mm (1.5 in.).

v Do not put excess weight on the cable at the connection point. Be sure that the

cable is well supported.

Fire suppression systems

A fire suppression system is the responsibility of the customer. The customer's own insurance underwriter, local fire marshal, or a local building inspector, or both, should be consulted in selecting a fire suppression system that provides the correct level of coverage and protection.

IBM designs and manufactures equipment to internal and external standards that require certain environments for reliable operation. Because IBM does not test any equipment for compatibility with fire suppression systems, IBM does not make compatibility claims of any kind nor does IBM provide recommendations on fire suppression systems.

Terminology and conventions used in this document

This guide uses the following terminology, command conventions, format conventions and keyboard conventions.

In this document, the term gateway describes IBM N series storage systems that have been ordered with gateway functionality. Gateways support various types of storage, and they are used with third-party disk storage systems. In this case, disk storage for customer data and the RAID controller functionality is provided by the back-end disk storage system. A gateway might also be used with disk storage expansion units specifically designed for the IBM N series models.

The term filer describes IBM N series storage systems that either contain internal disk storage or attach to disk storage expansion units specifically designed for the IBM N series storage systems. Filer storage systems do not support using third-party disk storage systems.

The terms system or storage system refer to either a gateway by itself or a filer, either by itself or with additional disk drives.

Active/active and high-availability terms

active/active configuration

In the Data ONTAP 7.2 and 7.3 release families, refers to a pair of storage systems (sometimes called nodes) configured to serve data for each other if one of the two systems stops functioning. Also sometimes referred to as active/active pairs.

cluster

In the Data ONTAP 7.1 release family, refers to a pair of storage systems (sometimes called nodes) configured to serve data for each other if one of the two systems stops functioning. In Data ONTAP 8.x ,acluster is a group of connected nodes (storage systems) that share a global namespace and that you can manage as a single virtual server or multiple virtual servers, providing performance, reliability, and scalability benefits.

HA (high availability)

In Data ONTAP 8.x, the recovery capability provided by a pair of nodes (storage systems), called an HA pair, that are configured to serve data for each other if one of the two nodes stops functioning.

HA pair

In Data ONTAP 8.x, a pair of nodes (storage systems) configured to serve data for each other if one of the two nodes stops functioning.

Storage terms

ACP Alternate Control Path is a protocol that enables Data ONTAP to manage

and control the storage expansion unit storage subsystem using a separate network from the data path, so management communication is not dependent on the data path being intact and available.

AT-FCX

The controller module of the EXN1000 serial advanced technology attachment (SATA) storage expansion unit.

Preparing for the installation 3

Handling static-sensitive devices

CAUTION: This system uses electronic components that are sensitive to static electricity. Static discharge from your clothing or other fixtures around you can damage these components. Put on an antistatic ESD strap and grounding leash to free yourself of static electricity before touching any electronic components.

Attention: Static electricity can damage electronic devices and your system. To

avoid damage, keep static-sensitive devices in their static-protective packages until you are ready to install them.

To reduce the possibility of electrostatic discharge (ESD), observe the following precautions:

v Limit your movement. Movement can cause static electricity to build up around

you.

v Handle the device carefully, holding it by its edges or its frame.

v Do not touch solder joints, pins, or exposed printed circuitry.

v Do not leave the device where others can handle and possibly damage the

device.

v While the device is still in its static-protective package, touch it to an unpainted

metal part of the system unit for at least two seconds. This drains static electricity from the package and from your body.

v Remove the device from its package and install it directly into your system unit

without setting it down. If it is necessary to set the device down, place it in its static-protective package. Do not place the device on your system unit cover or on a metal table. Take additional care when handling devices during cold weather because heating reduces indoor humidity and increases static electricity.

Planning and organizing the installation

This section identifies the shipment contents and the rules and regulations you need to observe for the proper installation of your system. It also provides an overview of the entire system installation process and the appropriate documentation references for the procedures.

DANGER

The weight of this part or unit is between 30.9 and 36.4 kg (68 and 80 lb). It takes three persons to safely lift this part or unit.

v Install the system at the bottom of your configuration, so that stacks or loops

extend above your system.

DANGER

To avoid hazardous conditions due to uneven mechanical loading, always install the heaviest devices in the bottom of the rack cabinet. Always install servers and optional devices starting from the bottom of the rack cabinet. (R001 part 1 of 2)

v When installing storage expansion units in a rack, do not exceed the maximum

storage limit for your system.

v Make sure that the ID on the back panel of each storage expansion unit matches

the ID specified on its label.

v Always install the storage expansion units fully loaded. Do not remove disk

drives to reduce the weight.

Guide to the installation process

The following table provides a guide to the filer installation process.

Attention: 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. 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.

If you are configuring a storage system as part of a high-availability (or active/active) 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 (or active/active) configuration, IBM recommends that you print and complete two copies of the configuration worksheet, one for each system node.

Refer to the Installation and Setup Instructions that shipped with your system and storage expansion units for complete installation details.

Note: The initial hardware installation of an N6200 series gateway is performed by IBM. Additional installation services can be performed by IBM through an IBM services offering. Contact your IBM representative for more information.

Configuring the Fibre Channel port

Each N6200 series system controller module provides two independent Fibre Channel ports, identified as 0c and 0d. SFPs must be firmly seated in all four ports before connecting cables.

The Fibre Channel ports can operate in target or initiator mode. Fibre Channel ports do not support mixed initiator/target mode. The default mode for the ports is initiator mode. You do not need to configure the ports to use them in initiator mode.

The Fibre Channel ports should be used in initiator mode to communicate with tape backup devices, such as in a TapeSAN backup configuration.

Fibre Channel ports on HBAs cannot be configured in target mode. They can only be used in initiator mode.

Configuring for initiator mode

About this task

To configure the system back to initiator mode, complete the following steps.

Procedure

1. Set the specified onboard ports to operate in initiator mode by entering the

following command:

fcadmin config -t initiator adapter

where adapter is the port number. You can specify more than one port.

Example: The following example sets onboard ports 0c and 0d to initiator mode.

fcadmin config -t initiator 0c 0d

2. Reboot the system by entering the following command:

reboot

3. Verify that the Fibre Channel ports are online and configured in the correct

state for your configuration by entering the following command:

12. The next step depends on your system configuration:

If your system has... Then...

One controller module in the chassis Reconnect the power cables to the power

supplies and to the power sources, and then turn on the power.

Two controller modules in the chassis The node already began rebooting; go to the

next step.

13. Enter one of the following commands at the firmware prompt:

v If you are configuring DHCP, enter the following command: ifconfig e0a

-auto

v If you are configuring manual connections, enter the following command:

ifconfig e0a -addr=filer_addr -mask=netmask -gw=gateway -dns=dns_addr

-domain=dns_domain

filer_addr is the IP address of the storage system.

netmask is the network mask of the storage system.

gateway is the gateway for the storage system.

dns_addr is the IP address of a name server on your network.

dns_domain is the Domain Name System (DNS) domain name. If you use this

optional parameter, you do not need a fully qualified domain name in the netboot server URL; you need only the server's host name.

Note: To netboot the node when your system is running in 7-Mode, use an IP address that is not the management IP address for the target.

Note: Other parameters might be necessary for your interface. Enter help ifconfig at the firmware prompt for details.

14. At the firmware prompt, enter the following command: netboot http://path_to_web-accessible_directory/netboot/kernel

15. Select the Install new software first option from the displayed menu. This menu option downloads and installs the new Data ONTAP image to the boot device. If you are prompted to continue the procedure, enter y when prompted.

16. Enter y when you see the following prompt:

This procedure is not supported for Non-Disruptive Upgrade on an HA pair. Do you want to continue? [y|no]y

17. Enter the path to the image.tgz when you see the following prompt:

What is the URL for the package? http://path_to_web-accessible_directory/image.tgz

18. Restore the backup configuration by entering y and then entering the IP address of the server containing the varfs.tgz file when you see the following screen:

**************************************************************** * Restore Backup Configuration * * This procedure only applies to storage controllers that * * are configures as an HA pair. * ** * Choose Yes to restore the "varfs" backup configuration * * from the SSH server. Refer to the Boot Device Replacement * * guide for more details. * * Choose No to skip the backup and recovery and return to the * * boot menu. * ****************************************************************

Do you want to restore the backup configuration now? {y|n} y

Start the restore_backup procedure on this node’s HA partner. The restore configuration has been copied from the HA partner to this node, would you like to use this restored copy now? {y|n}

19. Copy the varfs.tgz file from the HA partner node to the target node by

entering the following command from the partner node console:

restore_backup target_node.netboot_IP.address

Use the same IP address that was assigned to the target node and used for the netboot command.

20. Finish the restore backup on the target node by entering y when you see the

following screen:

The restore configuration has been copied from the HA partner to this node, would you like to use this restored copy now? {y|n} y CF device: /dev/ad0 found... Checking /dev/ad0s1 file system... success. Mounting /dev/ad0s1 to /cfcard... success. Checking /cfcard/x86/freebsd mount point... success. Restoring backup configuration...

21. Reboot the target node by entering the following command on the target node

console: boot_ontap

22. After the target node has rebooted and is displaying the Waiting for giveback message, complete the procedure by entering the following command on the partner node's console: cf giveback

Installing the boot device and transferring system files disruptively using netboot in a 7-Mode system:

You can transfer the system files and restore configuration information to your system by using netboot to copy the system files to the replacement boot device.

Before you begin

Important: This procedure is disruptive, even when using it with a system in an

HA configuration. You may experience a service outage or possible data loss during the procedure. IBM recommends using the nondisruptive procedure for HA configurations running Data ONTAP 8.0.1 and later in 7-Mode.

For copying system files to the boot device, you must have the following:

v The blank replacement boot device you received from your provider.

v Access to an HTTP server.
