Chapter 1. Introduction

IBM Fibre Array Storage Technology (FAStT) solutions support the large and growing data storage requirements of business-critical applications. These scalable IBM FAStT solutions offer you data access and protection to meet your existing enterprise storage requirements and prepare for the future.

Fibre channel is a new technology, similar to a high-speed network, that you can use to connect large amounts of disk storage to a server or cluster of servers. Fibre Channel technology supports increased performance, scalability, availability, and distance for attaching storage subsystems to network servers. The storage server provides for the attachment of Fibre Channel disk drives to give superior performance and redundancy.

Fibre channel technology supports applications that require large amounts of disk storage that is shared by two or more servers. With fibre channel, you can see a higher throughput rate over longer distances than is possible with Small Computer System Interface (SCSI) or with serial storage architecture (SSA) technology.

This document describes how to install and configure the following types of IBM TotalStorage FAStT600 storage servers:

“FAStT600 Model 6LU/6LX”

“FAStT600 Model 60U/60X” on page 2

“FAStT600 Turbo Model 60U/60X” on page 2

After

you review the introductory information that is provided in this chapter, go to Chapter 2, “Installing and configuring the storage server,” on page 15 to begin the installation process.

Note:

The figures used in this document are for illustrative purposes only. In some cases, the actual device might look different from the figure.

This applies particularly in cases where the FAStT600 single-controller storage server (Model 6LU/6LX) differs from the FAStT600 dual-controller storage server (Model 60U/60X).

Handling static-sensitive devices

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

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

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

precautions:

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

Handle the device carefully. Hold 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.

While the device is still in its static-protective package, you should hold the device and touch an unpainted metal part of the system unit for at least two seconds. This drains static electricity from the package and from your body.

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.

Chapter 1. Introduction

Page 30

Take additional care when handling devices during cold weather because heating reduces indoor humidity and increases static electricity.

Best practices guidelines

ensure optimal operation of your system, always follow these best practices

guidelines:

Back up the data on your storage drives periodically.

Before any planned system shutdown or after any system changes (additions, removals, or modifications), save controller subsystem profiles as explained in the IBM FAStT Storage Manager Installation and User’s Guide for your operating system.

Ensure that your system is in an optimal state before shutting down. Never turn the power off if any fault light is lit; be sure to resolve any error conditions before you shut down the system.

During any maintenance or attended power-up procedure, carefully follow the power-up sequence listed in “Turning on the storage server” on page 46. Each component of the subsystem should be checked that it is powered-on in the proper order during this entire power-up procedure to ensure the controller will be able to optimally access all of your storage subsystems.

The storage subsystem supports simultaneous power-up to the system components; however, you should always follow the power-up sequence listed in “Turning on the storage server” on page 46 during any attended power-up procedure.

v A

storage system in an optimal state should recover automatically from an unexpected shutdown and unattended simultaneous restoration of power to system components. After power is restored, call IBM support if any of the following conditions occur:

–

The storage subsystem logical drives and arrays are not displayed in the Storage Manager graphical user interface (GUI).

–

The storage subsystem logical drives and arrays do not come online.

–

The storage subsystem logical drives and arrays seem to be degraded.

FAStT600 Model 60U/60X only: To maintain power redundancy, plug the

FAStT600 dual-controller storage server’s right and left power supplies into two independent external power circuits through ac distribution units inside a rack cabinet or directly into external receptacles. Similarly, the right and left power supplies of the FAStT drive enclosures attached to the FAStT600 storage server should be plugged into the same two independent external power circuits as the FAStT600 storage server. This ensures that the FAStT600 storage server and all its attached drive enclosures will have power if only one power circuit is available. In addition, having all the right or all the left power supplies plugged into the same power circuit will enable the components in the storage subsystem

power on simultaneously during an unattended restoration of power. See

Figure 40 on page 41 for an example of redundant power connections.

Storage server components

The topics in this section show the components of the FAStT600 storage server.

All FAStT600 storage server models support hot-swap Fibre Channel hard drive CRUs and cooling fan CRUs, so you can remove and replace these components without turning off the storage server. In addition, the FAStT600 storage server models 60X/60U support hot-swap power supplies and RAID controller CRUs.

RAID controller

Each RAID controller contains ports for SFP modules that connect to the Fibre Channel cables. Two of the SFP ports (Host 1 and Host 2) are for host server attachment. On the FAStT600 Model 60U/60X, each RAID controller also has an additional port that connects FAStT EXP drive expansion units to the storage server.

Each RAID controller also contains a battery to maintain cache data in the event of a power failure. For more information, see “Cache memory and RAID controller battery” on page 54.

Hot-swap fans

The storage server has two interchangeable hot-swap and redundant fan CRUs. Each fan CRU contains two fans. If one fan CRU fails, the second fan CRU continues to operate. Both fan CRUs must be installed to maintain proper cooling within the storage server, even if one fan CRU is not operational.

Hot-swap power supplies

The storage server includes two hot-swap power supplies. Both power supplies must be installed to maintain proper cooling.

Exception: The FAStT600 single-controller storage server (Model 6LU/6LX)

has only one power supply. To maintain proper cooling, keep the cover on the second power supply bay.

Figure 6 shows the ports and switches on the back of the FAStT600 single-controller storage server (Model 6LU/6LX).

RAID controller

Each RAID controller contains several connectors and LEDs. Each controller has ports for SFP modules that connect to the Fibre Channel cables. Two of the ports are for host server attachment. (Each RAID controller on the FAStT600 Model 60U/60X also has an additional port that connects FAStT EXP drive expansion units to the storage server.) You first insert SFPs into the ports and then connect the Fibre Channel cables.

Host ports

The host ports are used to connect a Fibre Channel cable from the host systems. You first insert an SFP into the port and then connect a Fibre Channel cable. The two host ports in each controller are independent. They are not connected in the controller module as they would be in a hub configuration.

Ethernet port

The Ethernet port is for an RJ-45 10BASE-T or 100BASE-T Ethernet connection. Use the Ethernet connection to directly manage storage subsystems.

Expansion port (Model 60U/60X only)

The expansion port is used to connect up to three FAStT EXP drive expansion units to the RAID controllers. You first insert a SFP into the port and then connect a fibre channel cable.

Note: If you want to connect up to seven FAStT EXP drive expansion units,

you must purchase the FAStT600 Turbo option. See Table 4 on page

for more information.

Serial port

The serial port is used by service personnel to perform diagnostic operations on the RAID controllers.

Server/Enclosure ID switch

The Server ID switch settings range from 0 through 7, and you can set unique IDs ranging from 00 through 77.

Note: FAStT600 storage server and the FAStT EXP drive expansion units

are shipped with their Server ID/Enclosure ID switches set to 0 as the default. If you want to connect a FAStT600 to one or more EXP drive expansion units, you must set the Enclosure IDs of the EXPs

unique values (other than 0 or the current Server ID setting of the

FAStT600 storage server).

Note:

For controller firmware version 05.33.xx.xx, both host and expansion ports operate at 2 Gbps only. For controller firmware version 05.34.xx.xx and higher, the host ports can operate at either 1 or 2 Gbps (the expansion port speed is still locked at 2 Gbps only).

Heat output, airflow, and cooling

The maximum heat output of the FAStT600 is 390 watts (1330 BTU/hr). Each FAStT600 (Model 60U/60X) and FAStT EXP drive expansion units rack-mounted unit requires an airflow of 2.5 m

per minute (87 ft

per minute). The input air temperature to all racks is recommended to be in the range 10°C through 35°C (50°F through 95°F), with a recommended operating temperature of 22°C (72°F).

When racks that contain many FAStT600 units are to be installed together, the following requirements must be met to ensure that the FAStT600 units are adequately cooled:

Air enters at the front of the rack and leaves at the back. To prevent the air that

leaving the rack from entering the intake of another piece of equipment, racks must be positioned in alternate rows, back-to-back and front-to-front. This arrangement is known as “Cold Aisle / Hot Aisle” and is shown in Figure 7 on page 13.

Where racks are in rows, each rack must touch the rack that is next to it to reduce the amount of hot air that can flow around from the back of the rack into the intakes of the FAStT600 units that are in that rack. It is recommended that Suite Attach Kits be used to completely seal any gaps that remain between the racks. For details of Suite Attach Kits, contact your marketing representative.

Installing the storage server in a rack

Review the documentation that comes with the rack cabinet for safety and cabling information. When you install the storage server in a rack, consider the following factors:

Ensure that the room air temperature is below 35°C (95°F).

v Do

not block any air vents. Usually, leaving 15 cm (6 in.) of air space provides

proper airflow.

Plan the device installation starting from the bottom of the rack.

v Do

not extend more than one device out of the rack at the same time.

Remove the rack doors and side panels to provide easier access during installation.

Connect all power cords to properly wired and grounded electrical outlets.

Take precautions to prevent overloading the power outlets when you install multiple devices in a rack.

Statement 4:

≥ 18 kg

(39.7 lb)

≥ 32 kg

Setting server ID settings

The FAStT600 comes with a server ID switch that is used to identify the FAStT600

on a

Fibre Channel loop. The server ID switch is located on the back of the unit, as

shown in Figure 18 on page 23.

Note:

The Server ID switch is sometimes referred to as an “Enclosure ID” switch.

Figure 16. Rail adjustment screws

Figure 17. Server installation

IBM TotalStorage FAStT600 Fibre Channel Storage Server: Installation and User’s Guide

Page 47

Server ID switch settings set the server ID to a value from 00 - 77. Server ID switch

X1 is

for setting the ones position, and Server ID switch X10 is for setting the tens position. The settings of the two server ID switches, when used together, provide a two-digit ID of the server unit. The storage-management software uses the server

ID to

provide a correlation between the storage-management graphics and the physical storage unit. The ID indicates which physical unit corresponds to the storage-management software status.

Use Server ID switches X10 and X1 to set the server-unit ID to any value from 00 through 77.

Note: Each server unit should have a unique ID if it is going to be connected to

other FAStT EXP drive expansion units through the expansion drive loop ports. The Server ID setting is only valid for the drive loop. The amber Conflict LED (located on the right-side of the switch) will be lit if there is another unit in the drive loop that has the same ID setting as the server ID. See your storage server documentation for more information.

Configuring the storage subsystem

You must configure the storage subsystem configuration after you install the storage server in a rack. Use the information in the following sections to configure your storage subsystem configuration.

Storage subsystem management methods

Before you configure the storage subsystem, determine which method of storage subsystem management you want to use. You can manage the storage subsystems

either of two ways: Host-agent management or Direct-management.

Server ID Switch

Figure 18. Setting the Server ID

Chapter 2. Installing and configuring the storage server

Page 48

Note: If the operating system of the host server that the storage subsystem logical

drive(s) is mapped to is not the Microsoft

Windows NT

platform, you have

make an out-of-band direct management connection to the storage subsystem to set the correct host type first. Then, the server will be able to recognize the storage subsystem correctly for in-band management.

Host-agent management method:

This method requires host-agent software that is installed on the host server. The host-agent software allows the FAStT storage manager client program to manage the FAStT storage subsystem using the same Fibre Channel connections between the host server and the storage subsystem. You must install at least one management station and a software-agent host. The management station can be the host or a workstation on the Ethernet network. A management station will have the client software installed. Figure 19 shows the host-agent management method.

Direct-management method:

This method uses Ethernet connections from a management station to each controller. You must install at least one management station. The management station can be the host or a workstation on the Ethernet network. A management station will have the client software installed. Attach Ethernet cables to each management station (one pair per storage server). You will connect the cables to each controller later when you install the storage server. Figure 20 shows the direct management method.

Storage subsystems

Fibre Channel connections

FAStT600 Fibre Channel connections consist of two host Fibre Channel loops and

up to

one drive Fibre Channel loop, depending on the storage server model. These Fibre Channel connections are made through three SFP ports, which are labeled “Host 1,” “Host 2,” and “Expansion.”

Exception: The FAStT600 single-controller storage server (Model 6LU/6LX) does

not support drive loops or expansion units.

The host Fibre Channel loop provides the fibre path for host attachment. It can consist of Fibre Channel cables, SFPs, host bus adapters, Fibre Channel switches, and RAID controllers. The expansion drive Fibre Channel loop provides the fibre path to the hard disk drives (HDDs) that are outside the FAStT600 storage server

Figure 20. Direct-managed storage subsystems

Page 50

chassis. The drive Fibre Channel loop consists of Fibre Channel HDDs and optional FAStT EXP drive expansion units, Fibre Channel cables, and SFPs.

The FAStT600 dual-controller storage server (Model 60U/60X) supports redundant disk-drive-loop configurations. You can build a redundant drive loop by connecting one or more FAStT EXP drive expansion units to the redundant RAID controllers. Then, use dual fiber-optic cables to connect one expansion unit to another in a daisy-chain. For more information about adding expansion units, see “Connecting additional expansion units” on page 41.

Fibre Channel loop configurations

You must determine how the host systems will connect to the storage server. You can connect up to two host systems directly to the storage server, or you can connect more than two hosts to the fibre channel storage server through switches. The illustrations in the following sections show common host system configurations.

Note: The default is one partition. Four-partition and eight-partition configurations

are provided as option upgrades, as is the option of additional attachments

FAStT EXP drive expansion units. Contact your IBM resellers or marketing

representatives for more information.

Installing the storage subsystem configuration

Using the information gathered in the previous sections, install the host systems and host adapters.

Notes:

See the documentation provided with your host adapters for installation requirements and procedures.

Use the correct host adapter driver. For the latest supported host adapters and drivers, go to the following Web site:

www.pc.ibm.com/support

Attach

fiber-optic interface cables to each host adapter. You will connect the other end of the cables to the controller later in the installation process. For more information about handling fiber-optic cables, see “Installing fiber-optic cables” on page 36.

Note: Do not install the storage-management software at this time, if it is not

already installed. Install the storage server completely before you install the

software because you cannot test the software installation until the hardware

connected.

IBM TotalStorage FAStT600 Fibre Channel Storage Server: Installation and User’s Guide

Page 57

Chapter 3. Cabling the storage server

This chapter provides Fibre Channel and power cabling information for the storage server.

After you attach the storage server power cables, use the instructions that are provided in “Turning the storage server on and off” on page 45 for the initial startup

the storage server.

Working with SFPs and fiber-optic cables

Each RAID controller CRU contains ports for SFP modules that connect to the fiber-optic cables. Two of the SFP ports are for host server attachment. On the FAStT600 Model 60U/60X, each RAID controller also has an additional port that connects FAStT EXP drive expansion units to the storage server.

First, insert the SFP into the port, and then a insert a fiber-optic cable into the SFP. The other end of the fiber-optic cable connects to an external device. Note that SFPs are laser products.

Statement 3

CAUTION: When laser products (such as CD-ROMs, DVD drives, fiber optic devices, or transmitters) are installed, note the following:

v Do

not remove the covers. Removing the covers of the laser product could result in exposure to hazardous laser radiation. There are no serviceable parts inside the device.

Use of controls or adjustments or performance of procedures other than those specified herein might result in hazardous radiation exposure.

Danger

Handling fiber-optic cables

Before using 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.

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

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

become pinched when retracted.

| | | |

| | |

Page 58

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

v Do

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

(1.5 in.).

v Do

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

cable is well supported.

Installing SFP modules

The FAStT600 Storage Server host ports require SFP Modules. SFP modules are used to convert electrical signals to optical signals that are required for Fibre Channel transmission to and from RAID controllers. The FAStT600 Storage Server supports two types of SFP modules; one with a plastic pull-tab latch and one with a metal or plastic wire latch. After you install the SFP modules, you will use fiber-optic cables to connect the FAStT600 Storage Server to other Fibre Channel devices.

Before you install SFP modules and fiber-optic cables, read the following information:

The SFP module housing has an integral guide key designed to prevent you from inserting the SFP module improperly.

Use minimal pressure when you insert the SFP module into a port. Forcing the SFP module into a port could cause damage to the SFP module or the port.

You can insert or remove the SFP module while the port is powered on.

The operational loop performance is not affected when you install or remove an SFP module.

You must insert the SFP module into a port before you connect the fiber-optic cable.

You must remove the fiber-optic cable from the SFP module before you remove the SFP module from the port. See “Removing SFP modules” on page 36 for more information.

install an SFP module, complete the following steps.

Statement 3:

CAUTION: When laser products (such as CD-ROMs, DVD drives, fiber-optic devices, or transmitters) are installed, note the following:

v Do

not remove the covers. Removing the covers of the laser product could result in exposure to hazardous laser radiation. There are no serviceable parts inside the device.

Use of controls or adjustments or performance of procedures other than those specified herein might result in hazardous radiation exposure.

Power cabling

The FAStT600 dual-controller storage server (Model 60U/60X) uses two standard power cords, and the single-controller storage server (Model 6LU/6LX) uses only one.

You can connect the power cords to a primary power unit inside the rack, such as a properly grounded ac distribution unit, or to an external source, such as a properly grounded electrical outlet.

you have not already done so, attach the power cords, using the following

illustration for the location of the component parts.

Complete the following steps to attach the power cords.

Wrap the strain-relief clamp around the power cord approximately 20 cm (8 in.) from the power supply connection end.

Attach the power-supply nut, and tighten it securely.

Connect the power cord to the power supply.

Plug the power cord into a properly grounded electrical outlet.

Note: To maintain power redundancy on the FAStT600 dual-controller storage

server (Model 60U/60X), plug the storage server’s right and the left power supplies into two independent external power circuits through ac distribution units inside a rack cabinet or directly into external receptacles. Similarly, the right and left power supplies of the FAStT drive enclosures attached to the FAStT600 storage server should be plugged into the same two independent external power circuits as the FAStT600 storage server. See Figure 40 on page 41 for an example of redundant power cabling.

Exception: The FAStT600 single-controller storage server (Model

6LU/6LX) has only one power supply, so it does not support power redundancy.

“Turning the storage server on and off” on page 45 for the initial startup of

the storage server.

Installing the storage-management software

Install the storage-management software by using the procedures in the IBM FAStT

Storage Manager Installation and Support Guide for your operating system. Use

that document and the online help to configure the logical drives, partitions, and so

for the RAID controllers. Use your operating system documentation to make the

new logical drives accessible to the operating system.

Note: Make sure that you start the storage-management software to continuously

monitor the status of the storage server. For information about the importance of this information, see “Monitoring status through software” on page 50.

Note: You cannot connect expansion units to the FAStT600 single-controller

storage server (Model 6LU/6LX). If you are using the FAStT600 single-controller storage server, skip this section.

You can connect expansion units any time after you install the storage server, even while it is turned on and processing data. You can even install one expansion unit now and an additional expansion unit later.

Note: The standard FAStT600 dual-controller storage server (Model 60U/60X)

supports up to three FAStT EXP drive expansion units. (For EXP700 drive expansion units, you must also purchase the appropriate EXP700 drive expansion unit attachment options, as shown in Table 4 on page 3.)

Note:

you want to connect up to seven expansion units, you must purchase the Turbo option. Contact your IBM resellers or marketing representatives for more information.

Attention: You can add only new expansion units to the storage server. This

means that there must be no existing configuration information on the expansion unit that you want to install. If the expansion unit that you want to install currently contains logical drives or configured hot spares, and you want them to be part of the FAStT600 storage server, you must contact IBM for information. Improper drive migration might cause loss of configuration and other storage server problems.

connect an additional expansion unit, perform the following steps.

Note:

The following procedure is for ″cold-case″ (the FAStT600 storage server is powered down when expansion units are connected.

Follow the instructions in your expansion unit installation manual to set up and mount the new expansion unit.

Use the following procedure and Figure 41 on page 43 to connect a single expansion unit to the storage server:

Ensure that the Enclosure ID switch is set to a value different from the one set for the FAStT600 server and other drive expansion enclosures in the loop. Also, ensure that the link speeds of the expansion units are set to 2 Gb.

Use a fiber-optic cable to connect to the FC-Expansion Units port on the left RAID controller in the storage server to the In port on the left ESM board of the expansion unit.

Use a second fiber-optic cable to connect the FC-Expansion Units port on the right RAID controller in the storage server to the Out port on the right ESM board of the expansion unit.

Chapter 4. Operating the storage server

ensure optimal operation of your system, always follow these best practices

guidelines:

Periodically, perform a full backup of the data on your storage drives.

Before any planned system shutdown or after any system changes (additions, removals, or modifications), save controller subsystem profiles as explained in the Storage Manager guide for your operating system.

Ensure that your system is in an optimal state before shutting down. Never turn the power off if any fault light is lit; be sure to resolve any error conditions before you shut down the system.

v A

–

The storage subsystem logical drives and arrays are not displayed in the

Storage Manager client.

–

The storage subsystem logical drives and arrays do not come online.

–

The storage subsystem logical drives and arrays seem to be degraded.

FAStT600 models 60U/60X only: To maintain power redundancy, plug the

FAStT600 Storage Server’s right and left power supplies into two independent external power circuits through ac distribution units inside a rack cabinet or directly into external receptacles. Similarly, the right and left power supplies of the FAStT drive enclosures attached to the FAStT600 Storage Server should be plugged into the same two independent external power circuits as the FAStT600 Storage Server. This ensures that the FAStT600 Storage Server and all its attached drive enclosures will have power if only one power circuit is available. In addition, having all the right or all the left power supplies plug into the same power circuit will enable the components in the storage subsystem to power on simultaneously during an unattended restoration of power. See Figure 40 on page 41 for an example of redundant power connections.

Turning the storage server on and off

This section contains instructions for turning the storage server on and off under normal and emergency situations.

you are turning on the storage server after an emergency shutdown or power

outage, see “Restoring power after an emergency shutdown” on page 49.

| | | | | | | | | | | |

Page 70

Turning on the storage server

Important: You must turn on the drive enclosures and verify that the drive

enclosures’ FC connections are optimal by checking the indicator lights

before you turn on the FAStT600 Storage Server. The controllers might

not recognize the correct configuration if the hard disk drives are powered up after the FAStT600 Storage Server. For instructions on powering up the drive enclosures, refer to the drive enclosure documentation.

Note: Always wait at least 30 seconds between the time you turn off a power

switch and the time you turn on the power again.

Use this procedure to turn on the power for the initial startup of the storage server:

Verify that:

All communication and power cables are plugged into the back of the

storage server and a properly grounded ac electrical outlet

All hard disk drives are locked securely in place. For more information, see

“Installing hot-swap drives” on page 73.

Note: At least one drive must be present before you start the FAStT600.

Attention: If you are restarting the system after a normal shutdown, wait at

least 10 seconds before you turn on the power by using the power-on sequence

step 2.

Check the system documentation for the hardware devices that you intend to power up, and then determine the proper startup sequence. Use the following power-on sequence, where applicable:

Turn on the power to the supporting devices (for example, Ethernet switches

and management stations) before the storage server.

Attention: If you will be directly managing the storage array, you must set

the Dynamic Host Configuration Protocol (DHCP) or BOOT-P server before turning on the power. Setting up the server allows the controllers to obtain the corresponding IP address when you turn on the power to the array module. For more information, see the software installation guide for your operating system.

You must turn on the expansion units before the storage server. The controllers might not recognize the correct configuration if the drives are powered up after the storage server. For instructions on powering up the expansion units, see the expansion-unit documentation.

Turn on the power to the storage server; then restart or turn on the power to the host.

Note: Depending on your operating system, you might not have to restart

the host. For more information, see the software installation guide for your operating system.

Turn on the power to each device, based on the power-on sequence in step 2.

turn on power to the storage server, turn on the power-supply switches on the back of the storage server. You must turn on both power-supply switches to take advantage of the redundant power supplies.

Use the storage-management software and the Fault LEDs to check the overall status of the storage server and its components. All LEDs should be green on the front of the storage server. If they are not, use the storage-management software to diagnose the problem (see “Monitoring status through software” on page 50).

IBM TotalStorage FAStT600 Fibre Channel Storage Server: Installation and User’s Guide

Page 71

Note: The green Drive active LED and amber Drive fault LED below the drive

CRUs might flash intermittently as the drives spin-up. Wait until the storage server is finished powering up before checking the LEDs on the front of the storage server. For more information, see “Checking the LEDs” on page 50.

Turning off the storage server

Attention: Except in an emergency, never turn off the power if any storage server

Fault LEDs are on. Correct the fault before you turn off the power. Use the storage-management software and the Fault LEDs to check the overall status of the storage server and its components. All LEDs should be green on the front of the storage server. If they are not, use the storage-management software to diagnose the problem (see “Monitoring status through software” on page 50). This ensures that the storage server will power up correctly later. For more information, see “Troubleshooting” on page 98.

The storage server is designed to run continuously, 24 hours a day. After you turn

the storage server, do not turn it off. Turn off the power only when:

Instructions in a hardware or software procedure require you to turn off the power.

v A

service technician tells you to turn off the power.

v A

power outage or emergency situation occurs (see “Performing an emergency

shutdown” on page 49).

Statement 5

Use this procedure to turn off the power:

Before proceeding, use the storage-management software to determine the status of the system components and special instructions. The operating system software might require you to perform other procedures before you turn off the power.

Use the storage-management software to check the status of the storage server. Correct problems that are reported before you turn off the power.

Perform the following steps:

Stop all I/O activity to the storage server and attached expansion units. Make sure that:

All of the green Drive active LEDs on the front of the storage server (and

all attached expansion units) are not flashing.

Chapter 4. Operating the storage server

Page 72

The green Cache active LEDs on the back of the storage server are off.

Before the storage server is powered off, use the operating system software

either disconnect the storage server logical drives from the host or to

flush the logical drive data cache in the host server memory.

Attention: To turn off all power to the storage server, you must turn off both

power-supply switches and disconnect both power cords. Use the procedure in step 4 for the proper shutdown sequence.

Turn off the power to each device based on the following shutdown sequence:

Turn off power to the host before the storage server. If the host must stay powered on to support an existing network, see the operating system documentation for information about disconnecting the storage server logical drives from the host before the storage server is powered off.

Turn off power to the storage server before you turn off power to the expansion units. Turn off both power supply switches on the back of the storage server.

Turn off power to other supporting devices (for example, management stations, fibre-channel switches, or Ethernet switches).

Note: You do not need to perform this step if you are servicing only the

storage server.

After you perform the necessary maintenance procedures, turn on the power using the procedure in “Turning on the storage server” on page 46.

Restoring power after an unexpected shutdown

The storage server might shut down unexpectedly under any of the following conditions:

Attention: There might be data loss in each of the following cases:

The internal temperature of the storage server exceeds the maximum operating temperature (an over-temperature condition).

both fan CRUs fail or are unable to maintain an internal temperature below 70°C (158°F), one or both of the power supplies in the storage server will shut down. If both power supplies shut down, the unit is inoperable.

The storage-management software warns you if the temperature of the unit is rising, before it has risen sufficiently to shut down the power supplies. The first warning comes when the storage server internal temperature exceeds 45°C (113°F). The storage server shuts down if the temperature rises to 70°C (158°F).

There is a general power failure or a loss of power to the unit.

You are forced to shut down the storage server without performing the normal shutdown procedures (listed in “Turning off the storage server” on page 47) because of an emergency situation.

Attention: To avoid damage to the hardware, take special care when restarting

the system after an unexpected shutdown.

the storage server shuts down unexpectedly, go to “Restoring power after an

over-temperature shutdown” on page 49. Otherwise, go to “Restoring power after

emergency shutdown” on page 49.

IBM TotalStorage FAStT600 Fibre Channel Storage Server: Installation and User’s Guide

| | |

Page 73

Note: Unattended restoration of power is supported; however, if power restoration

attended, you should follow the best practices guidelines and the power

restoration sequence in “Turning on the storage server” on page 46.

Performing an emergency shutdown

Attention: Emergency situations might include fire, flood, extreme weather

conditions, or other hazardous circumstances. If a power outage or emergency situation occurs, always turn off all power switches on all computing equipment. This will help safeguard your equipment from potential damage due to electrical surges when power is restored. If the storage server loses power unexpectedly, it might be due to a hardware failure in the power system or midplane (see “Troubleshooting” on page 98).

Use this procedure to shut down the storage server during an emergency:

1. If

you have time, stop all I/O activity to the storage server by shutting down the

host or disconnecting the storage server logical drives through the host.

Check the LEDs (front and back). Make note of any Fault LEDs that are on so you can correct the problem when you turn on the power again.

Turn off all power-supply switches; then unplug the power cords from the storage server.

Restoring power after an emergency shutdown

Use this procedure to restart the storage server if you turned off the power-supply switches during an emergency shutdown, or if a power failure or a power outage occurred:

After the emergency situation is over or power is restored, check the storage server for damage. If there is no visible damage, continue with step 2; otherwise, have your system serviced.

After you have checked for damage, ensure that the power-supply switches are off; then plug in the storage-server power cords.

Complete step 2 on page 46 to determine the proper power-on sequence for your system.

Complete steps 3 and 4 on page 46 to turn on power to the devices in your system and to check the status of the storage server.

Restoring power after an over-temperature shutdown

Use this procedure to restart the storage server after an unexpected shutdown due

to an

over-temperature condition:

Make sure that the power-supply switches on the back of the storage server are turned off.

2. Do

whatever is necessary to cool the unit (replace the fans, use external fans to

cool the room, and so on).

Check all components and cables for visible damage. Do not start the storage

server if you find evidence of damage.

Complete step 2 on page 46 to determine the proper power-on sequence for your system.

When the internal temperature of the storage server is below 35°C (95°F), complete steps 3 and 4 on page 46 to turn on power to the devices in your system and to check the status of the storage server.

Chapter 4. Operating the storage server

Page 74

Monitoring status through software

Use the storage-management software to monitor the status of the storage server. Run the software constantly, and check it frequently.

Notes:

You can only monitor storage servers that are within the management domain of the storage-management software.

2. If

you do not install the Event Monitor service as part of the

storage-management software installation, the Enterprise Management window

the storage-management software must remain open. (If you close the window, you will not receive any alert notifications from the managed storage subsystems.)

For more information, see the Enterprise Management online Help.

The storage-management software provides the best way to diagnose and repair storage-server failures. The software can help you:

Determine the nature of the failure

Locate the failed component

Determine the recovery procedures to repair the failure

Although

the storage server has fault LEDs, these lights do not necessarily indicate which component has failed or needs to be replaced, or which type of recovery procedure you must perform. In some cases (such as loss of redundancy in various components), the fault LED does not turn on. Only the storage-management software can detect the failure.

For example, the recovery procedure for an IBM Predictive Failure Analysis

(PFA) flag (impending drive failure) on a drive varies depending on the drive status (hot spare, unassigned, RAID level, current logical drive status, and so on). Depending

the circumstances, a PFA flag on a drive can indicate a high risk of data loss (if the drive is in a RAID 0 volume) or a minimal risk (if the drive is unassigned). Only the storage-management software can identify the risk level and provide the necessary recovery procedures.

Note: For PFA flags, the General-system-error LED and Drive fault LEDs do not

turn on, so checking the LEDs will not notify you of the failure, even if the risk of data loss is high.

Recovering from a storage-server failure might require you to perform procedures other than replacing the component (such as backing up the logical drive or failing a drive before removing it). The storage-management software gives these procedures.

Attention: Not following the software-recovery procedures can result in data loss.

Checking the LEDs

The LEDs display the status of the storage server and components. Green LEDs indicate a normal operating status; amber LEDs indicate a possible failure.

It is

important to check all the LEDs on the front and back of the storage server when you turn on the power. In addition to checking for faults, you can use the LEDs on the front of the storage server to determine if the drives are responding to I/O transmissions from the host.

Cache memory and RAID controller battery

Each RAID controller in the FAStT600 standard storage server contains 128 MB of cache memory. Each controller in the FAStT600 Turbo storage server contains 896

MB of

cache memory.

Each controller also contains a rechargeable battery that maintains data in the cache for up to three days in the event of a power failure. The following sections describe these features and their associated LEDs.

Cache memory

Cache memory is memory that is used for intermediate storage of read and write

data on the FAStT600 dual-controller storage server’s RAID controllers (Model 60U/60X). Using cache memory can increase system performance. The data for a read operation from the host might be in the cache memory from a previous

operation (thus eliminating the need to access the drive itself), and a write operation

completed when data is written to the cache, rather than to the drives.

Note: On the FAStT600 single-controller storage server (Model 6LU/6LX), the RAID

controller’s cache memory is used for storing read data only. The controller firmware ignores a ″write-cache enabled″ setting. This protects data in the event of a controller failure, which would cause the cache to be inaccessible.

See the storage-management software documentation for information on setting cache memory options.

The RAID controller has a Cache active LED that displays the current status of the cache. The LED is on if there is data in the cache, and it is off if there is no data in the cache.

caching is enabled and the Cache active LED never comes on during I/O activity,

indicates that the cache memory has failed or the battery has failed (the green

Battery LED will be off).

Note: Always use the storage-management software to check your cache memory

settings before assuming a hardware failure.

Figure 46 shows the location of the Cache active LED on the front of the RAID controller.

RAID controller cache battery

Each RAID controller contains a sealed, rechargeable 4-volt lead-acid battery. This battery provides cache backup for up to three days in the event of a power loss.

The service life of the battery is three years, after which time the battery must be replaced. See the storage-management software for information on how to view and set the battery expiration date.

Each RAID controller has a green Battery LED on the back that indicates the battery status, as follows:

The LED is on and remains steady when the battery is fully charged.

The LED flashes when the battery is charging or performing a self-test.

The LED is off if the battery or the battery charger has failed.

The battery performs a self-test at startup and every 25 hours thereafter (during which time the Battery LED flashes). If necessary, the battery begins recharging at that time. If the battery fails the self-test, the Battery LED turns off, indicating a battery fault.

Data caching starts after the battery completes the startup tests.

Chapter 5. Installing and replacing components

This chapter provides instructions to help you install or remove customer replaceable units (CRUs), such as hot-swap drives, fans, RAID controllers, and power supplies.

For more field-replaceable unit (FRU) and Option part number information, see the following Web site:

www.ibm.com/storage/techsup.htm

Handling static-sensitive devices

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.

reduce the possibility of electrostatic discharge, observe the following

precautions:

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

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.

While the device is still in its static-protective package, touch it to an unpainted metal part of the storage server for at least two seconds. This drains static electricity from the package and from your body.

Remove the device from its package and install it directly into your storage server 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 storage server cover or any metal surface.

Take additional care when handling devices during cold weather because heating reduces indoor humidity and increases static electricity.

Upgrading your RAID controllers

This section describes the following upgrades:

“Upgrading FAStT600 Model 6LU/6LX to Model 60U/60X”

“Upgrading the FAStT600 Model 60U/60X from standard to Turbo option” on page 61

Upgrading FAStT600 Model 6LU/6LX to Model 60U/60X

upgrade from the FAStT600 single-controller storage server (Model 6LU/6LX) to

the FAStT dual-controller storage server (Model 60U/60X), you must purchase one

the following upgrade kits:

IBM FAStT600 Model 6LU/6LX Upgrade, IBM part number 24P8963

IBM FAStT600 Model 6LU/6LX Turbo Upgrade, IBM part number 24P8964

See

“FAStT600 Model 6LU/6LX” on page 1 for a description of the differences

between the two upgrade kits.

| |

| | |

| |

Page 82

The upgrade kits contain two FAStT600 controller CRUs, with cache memory battery installed, and one power supply. You must purchase additional SFPs and Fibre Channel cables separately to make Fibre Channel connections to the host ports on the second FAStT600 controller.

Use the following procedure for both upgrade kits.

Steps for upgrading from FAStT600 Model 6LU/6LX to Model 60U/60X

Before you begin:

Schedule downtime for the upgrade.

v If

you purchase additional storage capacity at the same time as the controller upgrade kit, do not connect the new drives or expansion units to the FAStT600 controllers until you complete the following tasks:

–

Finish the upgrade process

–

Verify that the upgraded storage server is in optimal state

you have premium features enabled in the existing FAStT600 storage server, ensure that you have access to the premium features key files before you begin the upgrade process. You will need to re-enable your premium features during the process.

Ensure that you have installed the latest version of FAStT Storage Manager. For more information, see the IBM FAStT Storage Manager Installation and Support

Guide for your operating system, or see the following Web site:

www-1.ibm.com/servers/storage/support/fastt/index.html

Use the Storage Manager Client to determine whether the system is in an optimal state. If it is not, fix the problem to return the system to an optimal state before you attempt the upgrade.

After the new controllers complete the boot process, the WWNN of the FAStT600 controllers will change. If you have any applications that rely on the previous WWNNs, such as FC switch zoning definitions, you must update the applications with the new WWNNs.

Complete

the following steps to upgrade from FAStT600 Model 6LU/6LX to Model

60U/60X, using either the standard or the Turbo option upgrade kit:

1. In

the Storage Manager Client, open a management connection to the

FAStT600 that you are upgrading.

Save the storage server profile to a disk location that is not in the FAStT600 that you are upgrading. In the Subsystem Management window, select View

—>

Storage Subsystem Profile. When the Storage Subsystem Profile

window opens, click Save As. The Save Profile window opens. Select an appropriate directory and choose a file name for the profile, then click Save.

Click Close to close the Storage Subsystem Profile window.

Complete any necessary server preparation tasks, because the disks will not

available during the upgrade process. For example, stop all programs,

services or processes in the host servers that access the logical drives.

Note: Make sure that you stop any background programs, services or

processes that write data to the logical drives. For example, Microsoft MSCS periodically writes to the Quorum disk.

Stop I/O to the storage server.

Unmount any mapped LUNs from the storage server.

Page 83

Note: In a Microsoft Windows

environment, remove the drive letter or the mount points of the mapped LUNs instead of unmounting the file systems.

6. If

applicable, remove the controller WWNN from the Fibre Channel switch

fabric zone definitions or any applications that use this WWNN info.

Wait one minute, then turn off the FAStT600 storage server that you are upgrading.

Label each cable that connects to the existing RAID controller CRU host ports

ensure that all cables will be properly reconnected to the new RAID

controller CRU.

Attention: Handle and install fiber-optic cables properly to avoid degraded

performance or loss of communications with devices. When working with fiber-optic cables, do not pinch them, step on them, or locate them in aisles or walkways. Do not overtighten the cable straps or bend the cables to a radius smaller than 38 mm (1.5 in.).

Remove the fibre-channel cables from the SFPs on the RAID controller CRU. (After removing the fibre-channel cables, insert their protective caps.)

10.

Remove the FAStT600 single controller CRU, as follows:

Push down on the latch (centered above the RAID controller), then pull both levers at the same time out of the locked position.

Grasp the pull-rings, then pull on the levers and remove the RAID controller.

11.

Unpack and insert the first upgrade FAStT600 controller CRU into the left-hand controller slot, which is marked “Controller A.”, as follows:

Slide the RAID controller all the way into the empty slot.

Close both levers until the latch locks into place.

12.

Remove the SFPs from host ports of the FAStT600 single-controller CRU and insert them into the host ports of the new FAStT600 controller CRU, which you installed in step 11. (Use the instructions in “Removing SFP modules” on page

and “Installing SFP modules” on page 34.)

13.

Remove the controller CRU blank from the right-hand controller slot, which is marked “Controller B.”

14.

Insert the new RAID controller into the slot marked “Controller B.”.

15.

Unpack the additional SFPs and insert them in the host ports of controller B.

16.

Remove the power supply blank from the right-hand power supply slot. Unpack and insert the upgrade power supply CRU into the slot (See “Installing a hot-swap power supply” on page 84 for more information about installing power supplies.)

17.

Reconnect the fibre-channel cables to their original host port locations in Controller A, using the instructions in “Installing fiber-optic cables” on page 36. Using the new fibre-channel cables, make the necessary fibre-channel connections to the host ports of controller B.

18.

DHCP/BootP was used to automatically set the IP address of the controller,

complete the following steps:

Record the MAC address of the upgrade controller

Modify the existing DHCP/BootP record of the RAID controller to be upgraded with the new MAC address

Notes:

Failure to modify the DHCP/BootP record will result in problems trying to manage the storage server using the existing IP address.

You must complete this step before you insert the upgrade controller into the FAStT storage server. For more information, see the instructions the appropriate IBM FAStT Storage Manager version 8.4x Installation and Support Guide.

c. If

you have created a DHCP/BootP record for controller A, you must add

one for controller B. Otherwise, you might not be able to manage controller

using the Ethernet network.

19.

Connect the power cord to the ac connector of the newly-added power supply CRU.

20.

Plug the power cord into a properly grounded electrical outlet.

21.

Turn on the power supply switches. Make sure that the green Power LED on the new power supply CRU is on, and that the amber Fault LED is off.

v If

the Power LED is off, the power-supply CRU might not be installed

correctly. Remove it, and then reinstall it.

Ensure that the electrical outlet is hot.

v If

the Fault LED is on, or if the Power LED stays off, contact your IBM

support representative.

Note:

maintain power redundancy on the FAStT600 dual-controller storage server (Model 60U/60X), plug the right and the left power supplies into two independent external power circuits through ac distribution units (inside a rack cabinet or directly into external receptacles).

Similarly, plug the right and left power supplies of any attached FAStT EXP drive expansion units into the same two independent external power circuits as the FAStT600. See Figure 40 on page 41 for an example of redundant power cabling.

22.

Wait a few minutes for the new controllers to complete the boot process.

23.

applicable, update the Fibre Channel switch fabric-zone definitions with the

newly generated controller World Wide Node Name (WWNN).

Note: If you have any other applications that rely on the previous FAStT600

controller WWNN, then you must also update the applications with the new WWNNs.

24.

Using the Storage Manager client, open a management connection to the FAStT600.

25.

Verify that the storage server does not have any errors (beside the battery failed/charging error). If there are missing LUNs, configurations, failed fibre-channel hard drives or fibre-channel hard drives that display the “need attention” icon, contact your IBM support representative.

26.

Set the enabled premium features back into an enabled and optimal state, using the existing premium features key files for the RAID controller that you removed from the original storage server.

Note: Before you complete this step, the premium features might display as

enabled, but they will be “out of compliance.”

27.

this is the Turbo upgrade option, use the Storage Manager Client to verify the firmware and NVSRAM. If the current versions are earlier than the versions that are included on the Turbo Option CD, reload the firmware and NVSRAM

the CD versions. Then, check the IBM Web site for any firmware or

NVSRAM updates.

28.

Enable full controller redundancy by making appropriate FC connections between controller B’s host ports and the HBA ports in the servers that are connected to controller A. You must also install the LUN failover driver in the host server.

Note:

the failover driver is already installed, you might have to reconfigure the failover settings, reboot the server, or both—depending upon which failover driver you used. If you do not install or reconfigure the failover driver, you will not have controller redundancy protection.

29.

the host server, reestablish the I/O connections to the mapped LUNs by

mounting the file systems or adding drive letter/mount points.

Note: You may have to reboot servers that use Microsoft Windows operating

systems to enable them to recognize the drives.

30.

this is the Turbo upgrade option, follow the Web activation instructions provided in the upgrade kit to activate the Storage Partitioning Premium Feature and register the ability to attach seven additional FAStT EXP drive expansion units.

Upgrading the FAStT600 Model 60U/60X from standard to Turbo option

you have purchased the FAStT600 Turbo option, you must replace your existing 256-MB memory controllers to 1-GB memory controllers shipped as part of the option. You should perform this upgrade with the power on as a hot-swap. It is also possible to perform this procedure as a cold-swap.

Note: A controller hot-swap replacement is when the controllers are replaced one

at a

time while the storage server is powered on. Care must be exercised to ensure a successful upgrade. Hot-swap is the preferred method for upgrading your controllers. A controller cold-swap replacement is when both controllers are replaced at the same time after the storage server is powered off. Power is turned back on to the storage server after the controllers are replaced.

This section contains the following procedures:

“Steps for hot-swap RAID controller upgrade”

“Steps for cold-swap RAID controller upgrade” on page 67

Steps for hot-swap RAID controller upgrade

Important:

You cannot hot-swap the RAID controller of a FAStT600 single-controller storage server (Model 6LU/6LX).

You must install the latest version of Storage Manager client software

the management workstation or in the host server connected to the FAStT600 that will be upgraded before you replace the old controller with the new controller. For more information, see IBM

FAStT Storage Manager Installation and Support Guide for your

operating system, or the following Web site:

www-1.ibm.com/servers/storage/support/fastt/index.html

This procedure must be done when the FAStT600 system is at a low I/O state. It is preferred that no I/Os are made to the FAStT600 server while the storage server is being upgraded.

The upgrade should be preformed when the system is in an optimal state. If it is not, fix the problem before attempting the upgrade. Use the Storage Manager client to determine if the system is in an optimal state.

You must have a management connection to the controller before attempting the upgrade because you need to use the Storage Manager client to set the controller to certain states before replacing it, and to verify its operating condition status.

You need to use the Storage Manager client to properly set the controller state by completing the following steps:

Disable controller caching.

Set the controller to offline state before replacing it.

Set the controller to online state after inserting the new controller.

Verify controller operating condition status after the new controller

brought online.

Save the configuration/profile before upgrading.

Each

RAID controller fits into the back of the storage server and has the following

components:

Battery

Cache memory

Two host ports and one expansion port

One Ethernet port

One serial port

Each

RAID controller has a unique hardware Ethernet address, which is printed on

label on the front. There is also a label giving the cache battery manufacturing

and installation dates on the top of the controller unit. Figure 48 shows the location

these items.

For information about the RAID controller cache memory and rechargeable battery, see “Cache memory and RAID controller battery” on page 54.

You must replace both controllers. Replace one controller at a time. To upgrade your RAID controller, complete the following steps:

Set the RAID controller on a dry, level surface away from magnetic fields. Save the packing material and documentation in case you need to return the RAID controller.

10.

DHCP/BootP was used to automatically set the IP address of the controller, record the MAC address of the upgrade controller and modify the existing DHCP/BootP record of the RAID controller to be upgraded with the new MAC address. Failure to modify the DHCP/BootP record will result in problems trying

manage the storage server using the existing IP address. This step must be performed before you insert the upgrade controller into the FAStT storage server.

11.

Install the new RAID controller, as follows:

Slide the RAID controller all the way into the empty slot.

Close both levers until the latch locks into place.

Attention: When you replace the old RAID controller, the

storage-management software automatically synchronizes the firmware between the existing controller and the new controller. After you replace a controller, always use the storage-management software to verify the firmware levels and nonvolatile storage random access memory (NVSRAM) files.

12.

Insert the SFPs according to the instructions in “Installing SFP modules” on page 34.

13.

Connect the fibre-channel cables to their original locations, according to the instructions in “Installing fiber-optic cables” on page 36.

14.

Wait approximately one minute, and then check the green Host Loop LED, green Expansion Loop LED, and amber Fault LED on the new RAID controller.

Note: If the Expansion Loop LED is off, the RAID controller might not be

16.

Check that the controller is online. Use either of the two following methods:

Use the Storage Manager client to verify that the controller is online (up)

and running by selecting the menu option to display the properties of the

controller that has just been replaced. If the controller is not up, you will get

controller-connection error window instead of the Controller Properties

window. Wait a minute and retry until you get the properties window.

Check the LEDs at the back of the controller. All Fault LEDs should be off

and the Host Loop and Expansion Loop LEDs should be on.

17.

the Fault LED is on, the Host Loop LED and the Expansion Loop LED stay off, or any other Fault LED is on, see the Storage Manager client for problem determination.

Note:

The battery LED may be flashing indicated battery charging is in progress.

18.

Repeat step 4 through step 17 for the second controller. However, do not continue with this step if the new controller is not in online and optimal state due to reasons other than battery charging and controller cache memory not matching.

Working with hot-swap drives

This section explains how you can increase the storage-server capacity by adding more drives or replacing existing drives with ones containing a larger capacity.

Figure 58 shows the location of the hot-swap drive bays that are accessible from the front of the storage server. To maintain proper cooling within the storage server, always keep a filler panel in each drive bay that does not contain a drive CRU.

Attention:

Never hot-swap a drive CRU when its green Activity LED is flashing. Hot-swap a drive CRU only when its amber Fault LED is completely on and not flashing or when the drive is inactive with the green Activity LED on and not flashing.

Before you install or remove drive CRUs, review the following information:

Filler panels

Storage servers without a full set of drives (14) contain filler panels in the unused drive bays. Before installing new drives, you must remove the filler

panels. Save the filler panels for future use. Each of the 14 bays must always contain either a filler panel or a drive CRU.

Drive CRUs

The RAID controller supports up to 14 (half-high or slim) 40-pin fibre-channel hard disk drives. These drives come preinstalled in drive trays. This drive-and-tray assembly is called a drive CRU. You can install the drive CRUs in the 14 drive bays on the front of the storage server.

Drive LEDs

Each drive CRU has two LEDs, which indicate the status for that particular drive. For information about the drive LED operating states and descriptions, see Figure 43 on page 51 and Table 7 on page 51.

Fibre-channel loop IDs

When you install a drive CRU in the storage server, the drive CRU connects into a printed circuit board called the midplane. The midplane automatically sets the fibre-channel loop ID to the default value 00.

Hot-swap hardware

The storage server contains hardware that you can use to replace a failed hard disk drive without turning off the storage server. Therefore, you can continue operating the system while a hard disk drive is removed or installed. These drives are known as hot-swap drives.

Slim drives

You can install slim, hot-swap drive CRUs.

Installing hot-swap drives

Before you begin: Take the following precautions.

Read the safety and handling guidelines that are provided in “Safety” on page iii and “Handling static-sensitive devices” on page 57.

Ensure that the current system configuration is working properly.

Back up all important data before you make changes to storage devices, such as hard disk drives.

Use

the following procedure to install hot-swap drives in the storage server. You can

install additional drives while the storage server is powered up and running.

Note: If you are replacing a drive, see “Replacing hot-swap drives” on page 75.

Read the instructions that come with the drive CRU.

Check for Fault LEDs. If any amber LEDs are lit, see “Checking the LEDs” on page 50 and “Troubleshooting” on page 98.

Determine the bay into which you want to install the drive.

Install the drive CRU:

Note: The hard disk drive comes with a tray already attached. Do not attempt

detach the drive 4 from the tray 3. See Figure 59 on page 74.

Chapter 5. Installing and replacing components

Page 98

Release the blue latch 1 on the drive CRU by pressing on the inside of the bottom of the tray handle. See Figure 59.

Pull the handle 2 on the tray out into the open position.

Slide the drive CRU into the empty bay until the tray handle 2 touches the storage-server bezel.

Push the tray handle 2 down into the closed (latched) position.

Check the drive LEDs.

When a drive is ready for use, the green Activity LED is either continuously

on or

rapidly flashing, and the amber Drive fault LED is off.

b. If

the amber Drive fault LED is completely on and not flashing, remove the

drive from the unit and wait 10 seconds; then reinstall the drive.

Use the Storage Manager client to configure the drive.

Update the information in “Records,” on page 101.

Replacing hot-swap drives

Drive problems include any malfunctions that delay, interrupt, or prevent successful I/O activity between the hosts and the hard disk drives. This includes transmission problems between the host controllers, the RAID controllers, and the drives. This section explains how to replace a failed drive.

Attention: Failure to replace the drives in their correct bays might result in loss of

data. If you are replacing a drive that is part of a RAID level 1 or RAID level 5 logical drive, ensure that you install the replacement drive in the correct bay.

Use the following procedure to replace hot-swap drives:

Check the hardware and software documentation that is provided with the system to see if there are restrictions regarding hard disk drive configurations. Some system fibre-channel configurations might not allow mixing different drive capacities or types within an array.

Check the Storage Manager client online help for recovery procedures for a drive that has failed. Follow the steps in the software procedure before you continue with this procedure.

Determine the location of the drive that you want to remove.

Attention: Never hot-swap a drive CRU when its green Activity LED is

flashing. Hot-swap a drive CRU only when its amber Drive fault LED is on and not flashing or when the drive is inactive with the green Activity LED on and not flashing.

the drive is not in a failed state (as indicated by a lit amber LED), manually

fail the drive using the Storage Management client before attempting to remove

from the drive slot.

Remove the drive CRU.

Press on the inside of the bottom of the tray handle to release the blue latch 1. See Figure 60 on page 76.

Pull the handle 2 on the tray 3 out into the open position.

Lift the drive CRU partially out of the bay.

d. To

avoid possible damage to the drive 4, wait at least 20 seconds before

you fully remove the drive CRU from the storage server to allow for the drive

spin down.

Chapter 5. Installing and replacing components

Page 100

Verify that there is proper identification (such as a label) on the drive CRU, and then slide it completely out of the storage server.

Install the new drive CRU.

Gently push the drive CRU into the empty bay until the tray handle 2 touches the storage-server bezel.

Push the tray handle 2 down into the closed (latched) position.

Check the drive LEDs.

When a drive is ready for use, the green Activity LED is either on continuously or rapidly flashing, and the amber Drive fault LED is off.

b. If

the amber Drive fault LED is on and not flashing, remove the drive from

the unit and wait 10 seconds; then reinstall the drive.

the drive is part of a defined RAID array, the array reconstruction (without

hot-spare) or copy-back (with hot-spare) operation automatically starts.

Upgrading drives

You can upgrade drives in the following two ways:

v By

adding drives to empty slots in the storage server (see “Installing hot-swap

drives” on page 73)

v By

replacing existing drives with larger capacity drives

Adding larger-capacity drives

This section provides guidelines for upgrading the drives in the storage server. Read the software documentation and this entire section to determine if you should use this procedure, use a modified version of this procedure, or use a different procedure that is provided by your operating system. Instructions that are provided

with your software should supersede anything stated in this document.

There are two methods for upgrading drives:

Replacing all the drives at the same time
