Tray Overviews

The Sun StorageTek 2540 Array, the Sun StorageTek 2530 Array, and the Sun StorageTek 2501 Array are a family of storage products that provide high-capacity, high-reliability storage in a compact configuration.

The Sun StorageTek 2540 Array is a modular, rackmountable controller tray. It is scalable from a single dual-controller tray (1x1) configuration to a maximum configuration of 1x3 with two additional drive expansion trays behind one controller tray.

All three of the trays can be installed in the following cabinets:

■ Sun Rack 900/1000 cabinet

■ Sun StorageTek Expansion cabinet

■ Any 19-inch wide, 4-post, EIA-compatible rack or cabinet with a front-to-back

depth between vertical cabinet rails of 61 cm to 91 cm (24 in. to 36 in.). The cabinet can have threaded or unthreaded cabinet rails.

The Sun StorageTek 2540 Array and the Sun StorageTek 2530 Array contain disk drives for storing data and controllers that provide the interface between a management and/or data host and the disk drives. The Sun StorageTek 2540 Array provides a Fibre Channel connection from the data host to the controller. The Sun StorageTek 2530 Array provides a Serial Attached SCSI (SAS) connection from the data host to the controller.

The Sun StorageTek 2501 Array drive expansion tray provides additional storage. You can attach the drive expansion tray to either the Sun StorageTek 2540 Array or the Sun StorageTek 2530 Array.

Rear-Access Components of the Trays

Components that are accessed from the rear of the Sun StorageTek 2540 Array and the Sun StorageTek 2530 Array controller trays include:

■ Controller Modules – Two removable controller modules.

■ Power-fan assembly – Two removable power supply modules with cooling fans.

The power-fan assembly is identical and interchangeable to the power-fan assemblies used for Sun StorageTek 2501 Array drive expansion tray.

FIGURE 1-4 Controller Tray Rear-Access Components

2. Power-Fan Assembly Modules

Components that are accessed from the rear of the Sun StorageTek 2501 Array drive expansion tray are:

■ I/O Modules (IOMs) – Two removable input/output modules

■ Power-fan assemblies – Two removable power supply modules with cooling

fans. The power-fan assembly is identical and interchangeable to the power-fan assemblies used for Sun StorageTek 2540 Array and the Sun StorageTek 2540 Array.

Chapter 1 Tray Overviews 5

FIGURE 1-5 Drive Expansion Tray Rear-Access Components

1. IOM Modules

2. Power-Fan Assembly Modules

Controllers

The Sun StorageTek 2540 Array and the Sun StorageTek 2530 Array have two controllers. The controllers manage the input/output (I/O) between the volumes and the data host. The controllers have an Ethernet connection to the management host for out-of-band management and contain a battery that provides backup power to the 1 GB DIMM cache memory for up to three days in the event of a power loss.

Because each controller tray contains two controllers, the data path through one controller can fail and the other controller provides a redundant data path to all of the disk drives. If a controller fails, you can replace the failed controller while the power is applied and the storage array is processing data (a hot swap). The system automatically updates the firmware for the new controller so that it matches the configuration database.

Each controller has a media access control (MAC) address that identifies it on the network. The MAC address for a controller is on a label on the controller. The MAC address label is attached to the controller in two places: at the top of the tray and at the rear of the tray.

The tray ID numbers are set by the trays themselves on first power on. However, you can change the setting through the Common Array Manager software. The tray ID numbers on both of the controllers in one controller tray are identical under optimal operating conditions.

Sun StorageTek 2540 Array

This Fibre Channel (FC) controller tray provides the following capabilities:

6 Sun StorageTek 2500 Series Array Hardware Installation Guide • March 2007

■ Two data host connectors per controller that can support either a fiber-optic

interface or a copper interface with 1, 2, or 4 Gb/s data host connection speed

■ One drive expansion tray Serial Attached SCSI (SAS) connector with 3 Gb/s drive

expansion tray connection speed

■ 512-MB or 1-GB mirrored cache

■ Maximum connection of 36 disk drives (one controller tray and two drive

expansion trays)

When fiber-optic cables are used to connect to the data host, a Small Form-factor Pluggable (SFP) transceiver is required to make the connection.

5. Not Used

SFP Transceivers

You can connect the Sun StorageTek 2540 Array to either copper host interface cables or fiber-optic host interface cables. If you use fiber-optic cables, you must install an SFP transceiver in each interface connector on the controller where a fiber-optic cable is to be installed. The SFP transceiver is required to translate the optical signals from the fiber-optic cable into digital signals for the controller.

Note – The SFP transceiver shown might look different from those that are shipped

with your controller tray. The difference does not affect transceiver performance.

Controller Tray and Drive Expansion Tray PowerFan Assembly

The power-fan assembly for the Sun StorageTek 2540 Array, the Sun StorageTek 2530 Array, and the Sun StorageTek 2501 Array is identical and interchangeable.

Note – A minimum of two disk drives must be operating in a controller tray or a

drive expansion tray to avoid generating a power-fan assembly error.

The power-fan assembly contains an integrated cooling fan. The power supply provides power to the internal components by converting incoming AC voltage to DC voltage. The fan circulates air inside of the tray by pulling air in through the vents on the front of the assembly and pushing the air out of the vents on the back of each fan.

Each tray contains two power-fan assemblies. If one power supply is turned off or malfunctions, the other power supply maintains electrical power to the tray. Likewise, the fans provide redundant cooling. If one of the fans in either fan housing fails, the remaining fan continues to provide sufficient cooling to operate the tray. The remaining fan runs at a higher speed until the failed fan is replaced. Replace the failed fan as soon as possible.

Chapter 1 Tray Overviews 9

Sun StorageTek 2501 Array

The drive expansion tray expands the storage capacity of a storage array. The controllers in the controller tray can connect to the drive expansion tray and access the disk drives in the drive expansion tray for additional storage. A drive expansion tray contains both physical components (disk drives, IOMs, and power-fan assemblies) and logical components (virtual disks and volumes).

Drive Expansion Tray IOM

The drive expansion tray contains two IOMs that provide the interface between the disk drives in the drive expansion tray and the controllers in the controller tray. The IOM also monitors sub-system parameters. Each controller in the controller tray connects to an IOM.

If one IOM fails, the other IOM provides a redundant data path to the disk drives. You can replace a failed IOM while the power to the storage array is turned on and the storage array is processing data (a hot swap).

Drive Expansion Tray IOM Connectors

The IOM connects to the controller tray and drive expansion trays with SAS cables. Each IOM in a drive expansion tray has two SAS expansion connectors. One connector shows an up arrow, and the other connector shows a down arrow.

FIGURE 1-9 SAS Connectors on the Drive Expansion Tray IOM

When connecting the SAS cable from an IOM in one drive expansion tray to an IOM in another drive expansion tray, connect from a down arrow to an up arrow. If the cable is plugged into two connectors with arrows of the same direction, communication between the two drive expansion trays is lost.

Caution – Potential loss of data access – Never remove a power-fan assembly, a

controller module, or a disk drive unless the Service Action Allowed LED is turned on or you are given specific instructions to do so by the Common Array Manager software Service Advisor.

If a module fails and must be replaced, the Service Action Required LED on that module turns on to indicate that a service action is required. The Service Action Allowed LED also will turn on if it is safe to remove the module. If there are data availability dependencies or other conditions that dictate that a module should not be removed, the Service Action Allowed LED remains off.

The Service Action Allowed LED automatically turns on or turns off as conditions change. In most cases, the Service Action Allowed LED turns on when the Service Action Required (Fault) LED is turned on for a module.

Note – If the Service Action Required (Fault) LED is turned on but the Service

Action Allowed LED is turned off for a particular module, you might have to service another component first. Check the Common Array Manager software Service Advisor to determine the action you should take.

Disk Drives

Disk drives for the Sun StorageTek 2500 Series Array have three components: a hard drive, a hard drive carrier, and an adapter card for connecting the disk drive to the midplane. The disk drives can be Serial Advance Technology Attachment (SATA) disk drives, Fibre Channel (FC) disk drives, or SAS disk drives.

Controller trays or drive expansion trays hold up to 12 disk drives, for a maximum of 36 disk drives in a storage array. To reach the maximum of 36 disk drives, the storage array must consist of one controller tray and two drive expansion trays.

Access to disk drives is from the front of the tray.

Refer to the storage array release notes for supported drives.

Note – The disk drives in your tray might differ in appearance from those shown

here. The variation does not affect their function.

Preparing for the Installation

Use the following procedures to prepare for installation:

■ “Preparing the Universal Rail Kit” on page 24

■ “Preparing the Tray” on page 25

■ “Preparing the Cabinet” on page 26

Preparing the Universal Rail Kit

Use the universal rail kit to mount the Sun StorageTek 2500 Series Array trays in any of the following cabinets:

■ Any standard Sun cabinet, such as the Sun Rack 900/1000 cabinet

■ Any 19-inch wide, 4-post, EIA-compatible rack or cabinet with a front-to-back

depth between vertical cabinet rails of 24-36 inches (with threaded or unthreaded cabinet rails).

■ The Sun StorageTek Expansion cabinet

Unpacking the Universal Rail Kit

Unpack the universal rail kit and check the contents.

The universal rail kit (part number 594-2489-02) comes with pre-assembled rails and contains the following items:

■ Left rail assembly

■ Right rail assembly

■ 10 8-32x3/8” panhead screws with lockwashers

■ 4 M4 flathead screws

■ 4 cabinet rail adapter plates (used for unthreaded cabinet rails only)

Loosening the Rail Adjustment Screws

To loosen the adjustment screws on the left and right rails:

Use a flathead screwdriver to loosen the two rail adjustment screws on each rail to allow adjustment of each rail length (

24 Sun StorageTek 2500 Series Array Hardware Installation Guide • March 2007

FIGURE 2-1).

FIGURE 2-1 Loosening the Rail Screws to Adjust the Rail Length

Note – The rails are preconfigured to adjust to cabinet rail depths of between 24

inches (609.6 mm) and 34 inches (863.6 mm).

Preparing the Tray

Caution – Two people are needed to lift and move the tray. Use care to avoid injury.

A traycan weigh up to 54.3 pounds (24.6 kg).

1. Unpack the tray.

2. Check the contents of the box for the following items:

■ Sun StorageTek 2500 Series Arraytrays (controller or expansion)

■ Ship kit for the controller tray

■ One pair left and right end caps (plastic bezels)

■ Four 4 Gbps FC SFPs (2 per FC Controller module)

Preparing the Cabinet

Select the cabinet in which you will be installing the array. Be sure the cabinet is installed as described in the installation instructions provided with it.

1. Stabilize the cabinet as described in the cabinet documentation.

2. If the cabinet has casters, make sure the casters are locked to prevent the cabinet from rolling.

3. Remove or open the front panel.

4. Remove or open the vented back panel.

Planning the Order of the Tray Installation

Install the trays starting with the controller tray at the lowest available 2RU tray slot in the cabinet. Next, install the expansion trays for the first controller tray. If room remains in the cabinet, repeat for the next controller and expansion trays.

Starting at the bottom distributes the weight correctly in the cabinet.

26 Sun StorageTek 2500 Series Array Hardware Installation Guide • March 2007

Attaching the Rails to a Cabinet

Depending on the type of cabinetin which you will install the tray, use one of the following procedures to attach the rails:

■ “Attaching the Universal Rail Kit to a Standard Sun or 19-Inch Cabinet With

Threaded Cabinet Rails” on page 27

■ “Attaching the Universal Rail Kit to a Standard 19-Inch Cabinet With Unthreaded

Cabinet Rails” on page 31

Each tray requires two standard mounting rack units (2RU) of vertical space in the cabinet. Each standard mounting rack unit (RU) has three mounting holes in the left and right cabinet rails. The top mounting hole of the lower RU is always closest to the bottom mounting hole of the upper RU, hence the divsion between RUs on a cabinet rail is between the two closeest mounting holes in a grouping.

The universal rails have an adjustable depth of 24” to 34”.

Attaching the Universal Rail Kit to a Standard Sun or 19-Inch Cabinet With Threaded Cabinet Rails

This procedure describes the steps to attach the universal rail kit to:

■ All standard Sun cabinets, including the Sun Rack 900/1000 cabinets

■ Sun StorageTek Expansion cabinets

■ All 19-inch wide, 4-post EIA-compatible racks and cabinets with the following

cabinet rail types:

■ M5 threaded

■ M6 threaded

■ 10-32 threaded

■ 12-24 threaded

■ circular unthreaded

1. To attach the universal rail kit to a cabinet withthese cabinet rail typesPosition

the front flange of the left universal rail behind the left front cabinet rail (

FIGURE 2-2).

Chapter 2 Installing Trays 27

Note – The RUs are not labeled on all racks, as they are on the Sun cabinets. The

rule of thumb to remember is that the division of RUs passes between the two closest rail holes in each set of holes (see FIGURE 2-2).

FIGURE 2-2 Positioning the Front of the Left Rail Behind the Left Front Cabinet Rail

2. Insert the 8-32 screws through the center holes in each RU of the rack into the

top and bottom holes in the Universal rail (

FIGURE 2-3).

These screws pass through the cabinet rail holes and screw into threaded holes in the Universal rail.

28 Sun StorageTek 2500 Series Array Hardware Installation Guide • March 2007

FIGURE 2-3 Securing the Left Rail to the Front of the Cabinet

3. Repeat Step 1 and Step 2 for the right rail.

Attaching the Universal Rail Kit to a Standard 19-Inch Cabinet With Unthreaded Cabinet Rails

This procedure describes the steps to attach the universal rail kit to:

Chapter 2 Installing Trays 31

■ All 19-inch wide, 4-post EIA-compatible racks and cabinets with unthreaded

cabinet rails (square hole racks).

To attach the universal rail kit to a cabinet with unthreaded cabinet rails, follow these steps first for the left rail and then for the right rail:

1. Hook a cabinet rail adapter plate over the front of the cabinet rail. (

FIGURE 2-6 Inserting the Cabinet Rail Adapter Plate on the Cabinet Rail

FIGURE 2-6)

Position the adapter plate over of the 2RU slot in which the tray is to be mounted. The hook on the top of the adapter plate hooks into the top hole of the upper RU. The flat flange on the bottom of the adapter plate fits into the bottom hole of the lower RU (

32 Sun StorageTek 2500 Series Array Hardware Installation Guide • March 2007

FIGURE 2-7).

FIGURE 2-7 Adapter plate in place on the Cabinet Rail.

2. Slide the front flange of the universal rail between the front cabinet rail and the top hook of the rail adater plate (

FIGURE 2-8).

Chapter 2 Installing Trays 33

FIGURE 2-8 Slide the flange of the rail behind the cabinet rail and between that and the

hook of the rail adapter plat.e, as shown.

3. Insert and tighten two 8-32 screws through the top and bottom holes in the adapter plate, through the cabinet rail, and into the top and bottom threaded holes in the universal rail mounting flange (

FIGURE 2-9).

34 Sun StorageTek 2500 Series Array Hardware Installation Guide • March 2007

FIGURE 2-9 Securing the Rail to the Front left of the Cabinet

4. Repeat Step 1 through Step 3 on the corresponding cabinet rail at the back of

the cabinet (

FIGURE 2-10).

Mounting the rail on the back of the cabinet is the same as mounting it to the front, after you extend the rail the necessary length to reach the rear cabinet rail.

Chapter 2 Installing Trays 35

FIGURE 2-10 Adjusting the Length of the Rail at the Back of the Cabinet

5. Insert and tighten two 8-32 screws through the top and bottom holes in the adpater plate, back cabinet rail, and universal rail mounting flange (

FIGURE 2-11).

The screws passes through the unthreaded holes of the adapter plate and cabinet rail mounting rail and screw into the threaded holes of the rail mounting flange.

36 Sun StorageTek 2500 Series Array Hardware Installation Guide • March 2007

FIGURE 2-11 Securing the Rail to the Back of the Cabinet

For extra stability, you can tighten the rail screws as in FIGURE 2-1.

6. Repeat Step 1 through Step 5 to install the right rail.

Installing a Tray in a Cabinet

Install the controller tray in the first empty 2RU slot at the bottom of the cabinet. If you are installing expansion trays, continue installing the trays from the bottom up.

1. Using two people, one at each side of the tray, carefully lift and rest the tray on the bottom ledge of the left and right rails (

Caution – Use care to avoid injury. A tray can weigh up to 55 pounds (25 kg).

FIGURE 2-12).

Chapter 2 Installing Trays 37

FIGURE 2-12 Positioning the Tray in the Cabinet

2. Carefully slide the tray into the cabinet until the front mounting flanges on the tray touch the vertical face of the cabinet (

38 Sun StorageTek 2500 Series Array Hardware Installation Guide • March 2007

FIGURE 2-13).

FIGURE 2-13 Array Controller Tray Installed

The tray has mounting flanges on both sides with three mounting holes in them. The top and bottom holes are large enough to fit over the heads of the screws already in the cabinet rails used to mount the universal rails. If the tray was shipped with end caps (bezels) clipped on the tray mounting flanges, remove them before sliding the tray all the way in over the mounting screw heads.

To remove an end cap , place your thumb on the lower front face of the cap and reach your forefinger underneath to the back bottom edge of the cap, then pull the cap towards you and slightly upwards.

On the rear of the array tray, a flat metal tab on each side corner slides into a special mounting clip on the rear of each universal rail, securing the back of the array tray. This makes the use of rear mounting screws to secure the tray in the rail unnecessary, especially in locations where the rack and trays are not likely to be moved. For racks that will be moved or shipped, Sun recommends that you install M4 screws through the hole in the tab and into the corresponding threaded hole in the rail as shown in

FIGURE 2-14.

Chapter 2 Installing Trays 39

FIGURE 2-14 Rail clip and rear mounting hole on rear of array tray.

3. Insert a single 8-32 pan head screw through the center hole in each front mounting flange and tighten (

40 Sun StorageTek 2500 Series Array Hardware Installation Guide • March 2007

FIGURE 2-15).

FIGURE 2-15 Securing the Tray to the Front of a Sun Rack 900/1000 Cabinet

4. Replace the end caps (bezels) that cover the mounting flanges on the front of the array tray.

On each front mounting flange, there is a small tab over which the end caps fit. The end caps have a slot on top for this tab.

a. Place the end cap over the tab so the tab can go into the slot.

b. Snap the bottom of the end cap into place.

Chapter 2 Installing Trays 41

Connecting the Power Cables

1. Verify that both power switches are turned off.

2. Verify that the circuit breakers in the cabinet are turned off.

3. Connect each power supply in the tray to a separate power source in the cabinet.

4. Connect the primary power cables from the cabinet to the external power source.

Note – Do not power on the array until you complete the procedures in this chapter.

The power-on sequence is described in detail in Chapter 4.

Intertray Cabling

This section describes how to cable a controller tray to expansion trays for several different configurations. Each controller has one expansion port ( Controller A controls drive channel 1 through the A-side drive modules; Controller B controls drive channel 2 through the B-side modules. Each drive channel provides a separate path for data transfer from the controller tray to the expansion trays; the two channels provide redundancy.

Array Configuration Naming Convention

The configuration naming convention is “controllers x trays” where the first number is the controller tray and the second is the sum of the controller tray and the number of expansion trays. For example, 1x1 is a standalone controller tray, 1x2 is the controller tray and one expansion tray, 1x is the controller tray and 2expansion trays (

TABLE 2-1).

TABLE 2-1 Controller and Expansion Tray Configurations

Configuration Identifier Controller Tray

Number of Expansion Tra ys

1x1 1 0

1x2 1 1

1x3 1 2

Note – Do not add more expansion trays than the array supports.

Use the following instructions to connect the dual-RAID controller tray to one or more expansion trays.

Chapter 2 Installing Trays 43

Connecting Expansion Trays

Keep the following points in mind when adding expansion trays to your storage array:

■ Expansion trays must be added with power to the array and I/O data transfer

turned off. If you need to add an expansion tray to an array that cannot be taken off-line, contact your Sun Technical Support representative before attempting to connect the new tray.

■ Controller and expansion trays are shipped with protective plastic plugs in the

SAS expansion ports. You must remove these before connecting cables.

■ Expansion trays are added serially, in a chain (actually two chains: channel one

through the A-side controller and modules, and channel two through the B-side controller and modules). The SAS cable from the expansion port on a controller connects to the In port (Up arrow) on an expansion tray drive module. The SAS cable from a drive module on expansion tray 1 to a corresponding drive module on expansion tray 2 connects from the Out port on expansion tray 1 to the corresponding In port on expansion tray 2. This pattern repeats for each additional drive module on a channel. See reverse cabling pattern.

■ To connect cables for maximum redundancy, controller B must be cabled to the

expansion tray B-side modules in the opposite order as the expansion tray A-side modules. That means the last drive module in the A-side chain from controller A must be the first drive module in the B-side chain from controller B. See

FIGURE 2-19 for an illustration of cabling for maximum tray level redundancy.

■ On all SAS cables, affix a label to each end of the cable. See “Drive Module Cable

Labeling” on page 47 for labeling tips.

FIGURE 2-19 for an illustration of this

44 Sun StorageTek 2500 Series Array Hardware Installation Guide • March 2007

Cabling an Expansion Tray to a Controller Tray

A Controller tray has two expansion ports, one on the Controller A module and one on the Controller B module. To connect an expansion tray, connect an SAS cable from each expansion port on the controller to each In port on the expansion tray.

FIGURE 2-18 shows a 1x2 array configuration consisting of one controller tray and one

expansion tray. Two SAS cables are required.

FIGURE 2-18 1x2 Array Configuration Cabling Example

To cable a 1x2 array configuration:

Expansion Tray

Controller Tray

1. Locate the Controller A and Controller B expansion ports at the back of the controller tray (

2. Locate the In and Out expansion ports at the A-side and B-side back of the expansion tray (

3. Connect one SAS cable between the Controller A expansion port and the Aside In port on the expansion tray (

4. Connect one SAS cable between the Controller B expansion port and the Bside In port on the expansion tray (

FIGURE 2-16).

FIGURE 2-17).

FIGURE 2-18).

Cabling an Expansion Tray to Another Expansion Tray

Each additional expansion tray is added to the preceding expansion tray by connecting SAS cables from the Out ports of the first tray to the In ports of the next tray.

FIGURE 2-19 illustrates a 1x3 array configuration consisting of one controller tray

Chapter 2 Installing Trays 45

and two expansion trays. The cable connections on the B-side are reversed (the cable from the controller A expansion port goes to the In port of expansion tray 1; the cable from the controller B expansion port goes to the In port on expansion tray 2) for maximum redundancy. This pattern continues for each additional tray you add. Two more SAS cables are required for each additional tray.

FIGURE 2-19 1x3 Array Configuration Cabling

To cable a 1x3 array configuration for maximum redundancy:

6. Connect one SAS cable between the expansion tray 2 B-side Out port and the B-side In port of expansion tray 2 (

FIGURE 2-19).

Drive Module Cable Labeling

Labels for the drive cables identify which controller ports and which expansion connections in an expansion tray you use when you attach cables between a controller and the drive modules on an expansion tray. Cable labels are useful if you need to disconnect cables to service a controller. Attach a label to each end of the cable. Use this design to create labels for drive cables:

■ Controller ID (for example, Controller A)

■ Expansion tray ID (for example, Tray A)

■ Expansion port ID (for example, In or Out)

■ Drive module ID

Example Label Abbreviation

In this example, the storage configuration has the following characteristics:

■ Drive channel 1

■ Controller A, drive channel 1

■ Drive module 1

■ Expansion Tray A (which is the left drive module), Out port

Using this design, the label includes the following information:

CtA-Dch1, Dm1-Tray_A (left), Out

Simplex Configurations

A simplex configuration is a 2530 Array with a single controller and a single backend channel. By definition, there is a single path SAS connection to the data host, and no redundancy is available. There can be expansion modules on the single backend channel.

Chapter 2 Installing Trays 47

Simplex cabling is the same as the cabling on a single channel of an ordinary array, such as that shown on the A-side in procedures in a simplex configuration are the same as those for a duplex configuration with a failed controller (with the exception of the service procedures targeted at the failed controller). These procedures are available in Service Advisor. Maintenance procedures such as firmware updates or servicing of the controller or expansion modules will cause loss of access to the array during the performing of the procedure, since there is no backup channel.

Performance and default behavior are the same as a duplex configuration with a failed or missing controller. Write cache is by nature in write-through mode because there is no cache mirroring possible.

There are three ways to establish a connection between the management host and Ethernet port 1 of an array controller:

■ “Attaching the Ethernet Ports to the LAN of the Management Host” on page 50

■ “Attaching the Ethernet Ports to the Management Host Using an Ethernet Hub”

on page 51

■ “Attaching the Ethernet Ports Directly to the Management Host With a Cross-

Over Cable” on page 51

Attaching the Ethernet Ports to the LAN of the Management Host

To attach the Ethernet ports to the local area network (LAN) of the management host:

1. Locate the Ethernet port for Controller A and Controller B at the back of the controller tray (

2. Connect Ethernet cables to the Ethernet ports of each controller.

3. Connect the other end of each Ethernet cable to the LAN on which your management host resides (preferably on the same subnet).

Attaching the Ethernet Ports to the Management Host Using an Ethernet Hub

To attach the Ethernet ports and the management port Ethernet interface to an Ethernet hub on a private subnet:

1. Locate Ethernet ports on Controller A and Controller B at the back of the controller tray (

2. Connect Ethernet cables to the Ethernet ports of each controller module.

3. Connect the other end of each Ethernet cable to an Ethernet hub.

4. Connect an Ethernet port on the management host to the Ethernet hub.

FIGURE 3-1).

Attaching the Ethernet Ports Directly to the Management Host With a Cross-Over Cable

Note – This method would typically be used only to establish temporary IP

connectivity between the management host and the controller’s Ethernet ports.

To attach the Ethernet ports directly to the management host using cross-over cables:

1. Locate the Ethernet ports for Controller A and Controller B at the back of the controller tray (

2. Obtain and connect Ethernet cross-over cables to the Ethernet port of each controller module.

3. Connect the other end of each Ethernet cable directly to your management host Ethernet ports.

Connecting Data Hosts to the 2540 Array

The Sun StorageTek 2540 Array connects to data hosts through Fibre Channel (FC) cables.

Chapter 3 Connecting the Management Host and Data Hosts 51

Note – For maximum hardware redundancy, you must install a minimum of two

HBAs in each host. Dual-port HBAs give you two paths into the storage array but do not ensure redundancy if the HBA fails.

2540 Array Data Host Connection Topologies

You can connect data hosts to access the Sun StorageTek 2540 Array directly to the array, or through Fibre Channel (FC) switches to the array. The following figures illustrate four possible host connection topologies for the 2540 Array:

■ Direct connection from a single data host server (FIGURE 3-2)

■ Direct connection from two data host servers (FIGURE 3-3)

■ Data host connection through Fiber Channel switch fabric (FIGURE 3-4)

■ Mixed connection, direct and through switch (FIGURE 3-5)

Host Cable Labeling

Labels for host cabling identify which host HBA ports and which controller ports you use when you attach cables between the host and the controller. Cable labels are useful if you need to disconnect cables to service a controller. Attach a label to each end of the cable. Use this design to create labels for host cables:

■ Host name and HBA port

■ Controller ID (for example, Controller A)

■ Host channel ID (for example, Host channel 1)

Example Label Abbreviation

In this example, the storage configuration has the following characteristics:

■ Host name is “Engineering”

■ Host HBA 1, port 1

■ Controller A, channel 1

Using this design, the label includes the following information:

Heng-HBA1/P1, CtA-Hch1

Next Steps

After you connected the management and data hosts, you can power on the trays, as described in Chapter 4.

Chapter 3 Connecting the Management Host and Data Hosts 59

CHAPTER

Powering On the Array

This chapter describes initial tray power-on procedures. Perform the following procedures in the order listed:

■ “Before Powering On” on page 61

■ “Powering On the Array” on page 62

■ “Powering Off the Array” on page 63

■ “Next Steps” on page 64

Before Powering On

You can set up a Dynamic Host Configuration Protocol (DHCP) server to issue the IP address to each controller. If a DHCP server is not available, the controller tray defaults to internal static IP addresses. (See the Sun StorageTek Common Array Manager Software Installation Guide for information about configuring IP addresses on array controllers.)

For instructions on configuring IP addresses on the array controllers, see

“Configuring the IP Address of the Array Controllers” on page 74. For instructions

on how to set up the DHCP server, see “Configuring a DHCP Server” on page 81.

Powering On the Array

Use this procedure to turn power on for all trays installed in the cabinet (FIGURE 4-1).

Note – The order in which you power up the trays is important. Be sure to power

on the controller tray last in order to ensure that the disks in the expansion trays have enough time to spin completely before being scanned by the redundant array of independent disks (RAID) controllers in the controller tray.

FIGURE 4-1 Tray Power Connectors and Switches

Controller A

1. Prepare the power cables as specified in “Connecting the Power Cables” on

page 42.

2. Turn on the cabinet circuit breakers, if applicable.

3. Press the power switches at the back of each expansion tray to the On position.

While the tray powers on, the green and amber LEDs on the front and back of the controller tray turn on and off intermittently. Depending on your configuration, it can take several minutes for the tray to power on. When the power-on sequence is complete, the LEDs are steady green.

Wait until all the disk drive indicator lights on the expansion trays are steady green before proceding to the next step.

4. Press each power switch at the back of the controller tray to the On position.

Controller B

1. Controller A power switch

2. Controller B power switch

5. Check the status of each tray.

After the power-on sequence is complete, confirm the following:

■ The green OK/Power LEDs on each drive in the tray are steady on.

62 Sun StorageTek 2500 Series Array Hardware Installation Guide • March 2007

■ The green OK/Power LED on the tray is steady on.

If all tray and drive Ok/Power LEDs are steady green and the amber Service Required LEDs are off, the power-on sequence is complete and no faults have been detected.

Powering Off the Array

The array rarely needs to be powered off. You remove power only when you plan to physically move the array to another location or are adding additional trays to a controller.

To power off the array, do the following:

1. Stop all I/O from the hosts, if connected, to the storage system.

2. Wait approximately 2 minutes until all disk drive LEDs have stopped flashing.

Note – If Disk Scrubbing is enabled, the disk drive LEDs will continue to flash after

the 2-minute period has elapsed. By waiting the 2-minute period, you ensure that the data residing in cache has been written to disk. The LED flash rate during disk scrubbing (slow, periodic blink) is different from the flash rate of I/O (fast, random).

After the 2-minute period, data residing in cache is written to disk and the battery mechanisms are disengaged.

3. Check the Cache Active LED on the controller ( outstanding cache needs to be written.

If the LED is on, there is still data that needs to be flushed and written to disk.

4. Ensure that the Cache Active LED is no longer flashing before powering off the array.

5. Press each power switch at the back of the controller tray to the Off position.

6. Press the power switches at the back of each expansion tray to the Off position.

CHAPTER

Data Hosts, HBAs, and Other Software

This chapter describes how to install data host software, HBAs, and other software on different host platforms. It contains the following sections:

■ “Data Host Software” on page 65

■ “Setting Up a Data Host On a Solaris System” on page 66

■ “Installing Data Host Software for Operating Systems Other Than Solaris” on

page 69

■ “Enabling Multipathing Software” on page 70

■ “Next Steps” on page 71

Data Host Software

The data host software contains tools that manage the data path I/O connections between the data host and the array. This includes drivers and utilities that enable array management hosts to connect to, monitor, and transfer data in a storage area network (SAN).

Note – Some management hosts can also be used as data hosts.

HBAs and Drivers

A Host Bus Adapter (HBA) is a network interface card that manages all data I/O on your data host. The specific HBAs you need depend on the data host server platform, operating system, data transport (SAS or FC), and data transfer rates used

in your storage area network. HBAs must be ordered separately, from Sun or their respective manufacturers. Sun HBAs can be ordered from:

/www.sun.com/storagetek/storage_networking/hba/

The required versions of HBAdrivers must be installed on the data host before you can set up a data host. The Sun StorageTek 2500 Series Array Release Notes lists the data host requirements for HBAs and drivers. Refer to the specific vendor HBA documentation for instructions on installing HBA drivers.

Multipathing

Data host software controls the data path between the data host and the array. Since there can be more than one path between the host and the array for redundancy, this function is called multipathing.

You must install data host software (including multipathing) on each data host that communicates with the Sun StorageTek 2500 Series Array. The multipathing software you need depends on the host platform, HBA, and the data transport (SAS or FC) in your storage area network. This information is listed in the latest version of the Sun StorageTek 2500 Series Array Release Notes.

Setting Up a Data Host On a Solaris System

The Sun StorageTek 2500 Series Array provides data path support for data hosts running Solaris, Windows 2000, Windows Server 2003, Red Hat Linux, HP-UX, NetWare, and IBM AIX operating systems. This section applies to hosts running Solaris OS 8, 9, and 10.

See the Sun StorageTek 2500 Series Array Release Notes for the latest supported operating system versions.

Chapter 5 Data Hosts, HBAs, and Other Software 71

72 Sun StorageTek 2500 Series Array Hardware Installation Guide • March 2007

CHAPTER

Configuring IP Addressing

In order for there to be an out-of-band Ethernet connection between the local management host and the array controllers, the management host and the array controllers must have valid IP addresses.

This chapter describes how to configure IP addressing on the local management host and the array controllers. It contains the following sections:

■ “About IP Addressing” on page 73

■ “Configuring the IP Address of the Array Controllers” on page 74

About IP Addressing

The Sun StorageTek 2500 Series Array is managed out-of-band by way of a standard Ethernet connection between the redundant array of independent disk (RAID) controllers and your management host.

Perform the following procedures to ensure that the local management host and the array controllers have valid IP addresses:

■ Configure IP addresses for the array controllers (see “Configuring the IP Address

of the Array Controllers” on page 74)

■ Configure an IP address for the management host (see the Sun StorageTek Common

Array Manager Software Installation Guide)

Configuring the IP Address of the Array Controllers

You can configure two types of IP addressing for the Ethernet port of each array controller:

■ Dynamic Host Configuration Protocol (DHCP) IP addressing – IP addresses for

the Ethernet port are assigned dynamically from a DHCP server running bootstrap protocol (BOOTP) services. An IP address assigned to an Ethernet port is held only as long as needed. By default, DHCP is not enabled at initial poweron, so you must connect to it using a serial console or the Common Array Manager and the controller’s static IP address, and then enable DHCP.

■ Static IP Addressing – You assign a specific IP address to the Ethernet port of each

controller. Static IP addresses remain in effect until you modify or remove them or you change the method of IP addressing for the Ethernet port to DHCP.

By default, if the array controllers cannot find a DHCP server upon initial poweron, an internal IP address is assigned to Ethernet port 1 of each controller:

■ The Ethernet port of Controller A is assigned IP address 192.168.128.101

■ The Ethernet port of Controller B is assigned IP address 192.168.128.102

■ The default subnet mask for each port is 255.255.255.0

To configure the Ethernet port on a controller with either dynamic or static IP addressing, see one of the following sections:

■ “Configuring Dynamic (DHCP) IP Addressing” on page 74

■ “Configuring Static IP Addressing” on page 75

Configuring Dynamic (DHCP) IP Addressing

If BOOTP services are available on the DHCP server at initial array power on, this server assigns a dynamic IP address for the Ethernet port on each controller.

If a DHCP server is not available, the controller tray defaults to internal static IP addresses as described in “Configuring the IP Address of the Array Controllers” on

page 74.

If you want to set up a DHCP server, refer to Appendix A for a description of how to configure BOOTP services in Sun Solaris or Microsoft Windows environments.

You can restore DHCP IP addressing to Ethernet port 1 of either controller in either of three ways:

■ Start a DHCP server on the same subnet, then reboot the 2500 Series Array.

74 Sun StorageTek 2500 Series Array Hardware Installation Guide • March 2007

■ Using the serial port interface (see “Using the Serial Port Interface to Assign IP

Addresses” on page 75)

■ Using the Sun StorageTek Common Array Manager (see the Sun StorageTek

Common Array Manager Software Installation Guide)

Configuring Static IP Addressing

There are two methods of assigning static IP addresses to the Ethernet ports of a controller:

■ The serial port interface (see “Using the Serial Port Interface to Assign IP

Addresses” on page 75)

■ The Common Array Manager (see the Sun StorageTek Common Array Manager

Software Installation Guide)

Note – It is recommended that you use the serial port interface to assign IP

addresses to the Ethernet port of each controller, if possible.

Using the Serial Port Interface to Assign IP Addresses

You can use the serial port interface on a controller to set the IP address for the Ethernet port on the controller.

To use the serial port interface to configure IP addressing for the Ethernet port of each controller, you must complete the tasks described in the following sections:

■ “To Connect a Terminal to the Serial Port” on page 75

■ “To Set Up the Terminal Emulation Program” on page 76

■ “To Establish a Connection With the Serial Port” on page 77

■ “To Configure the IP Addresses” on page 78

▼ To Connect a Terminal to the Serial Port

You will establish a serial connection to each controller, Controller A and Controller B. Two mini-DIN to RJ45 serial port cables are supplied with each controller tray.

Chapter 6 Configuring IP Addressing 75

To connect a terminal to the serial port of a controller:

1. Connect the 6-pin mini-DIN connector of the serial cable to the serial port connector (diagnostic port) on the controller (

FIGURE 1-3 on page 6).

2. Connect the RJ-45 connector of the serial cable to the serial port connector on the terminal. It may be necessary to use an RJ45-DB9 adapter between the serial cable RJ-45 connector and the serial port of the terminal.

3. For PC and laptop serial connections, you will also need to use a null modem. Connect the null modem between the serial cable or RJ45-DB9 adapter and the PC serial port.

Note – If your PC does not have a serial port, you can use a USB–Serial Port adapter

(separately available from third-party vendors; not included with 2500 Series Array ship kits).

▼ To Establish a Connection With the Serial Port

To establish a connection with the serial port and display the Service Interface menu:

1. Press Break.

Note – The array serial port requires that the break character be received. Use the

appropriate escape sequence for your terminal setup to send the required break character to the array controller, For example, you generate the Break character on some terminals by pressing the Control and Break keys simultaneously.

The serial port responds with a request to synchronize with the baud rate of the terminal:

Set baud rate: press <space> within 5 seconds

2. Press the space bar within five seconds.

The serial port confirms the established baud rate for the connection:

Baud rate set to 38400

3. Press Break (see Note above)

The serial port responds with the following message:

Press within 5 seconds: <S> for Service Interface, <BREAK> for baud rate

4. Press S to access the Service Interface menu.

Note – Send Break to synchronize the serial port to a different terminal port rate

(see Note above).

CHAPTER

Configuring a DHCP Server

This appendix describes how to configure bootstrap protocol (BOOTP) services in a Sun Solaris and Microsoft Windows environment. It contains the following sections:

■ “Before You Begin” on page 81

■ “Setting Up a Solaris DHCP Server” on page 81

■ “Setting Up a Windows 2000 Advanced Server” on page 86

Dynamic IP addresses are assigned through dynamic host control protocol (DHCP) server BOOTP services.

Before You Begin

You need each controller’s media access control (MAC) address to configure the DHCP server. The MAC address is located on the bar code label at the back of each redundant array of independent disks (RAID) controller. Since there are two controllers per array, you need two MAC addresses.

Setting Up a Solaris DHCP Server

The following procedure provides an example of how to set up a DHCP server with the BOOTP option for the Solaris 8, 9, and 10 Operating Systems. Your environment may require different steps.

1. Modify the netmasks line of the /etc/nsswitch.conf file as shown here:

#netmasks: nis [NOTFOUND=return] files netmasks: files nis [NOTFOUND=return]

2. Start the DHCP wizard by issuing the following command at the command line:

/usr/sadm/admin/bin/dhcpmgr &

The following window is displayed:

The wizard will prompt you for information related to the configuration, network address, and subnet mask of the controller tray. Select or enter the following information:

■ Data storage format: Text files

■ Nameservice to store host records: Do not manage hosts records

■ Length of lease:

■ Network Address: Network address of Controller A

■ Subnet Mask: For example, 255.255.255.0

■ Network Type: Local-Area (LAN)

■ Router: Use router discovery protocol

Your summary page should look similar to the following example:

3. Verify your configuration information and click Finish.

4. When you are prompted to configure addresses for the server, click Yes.

The Add Address to Network wizard is displayed.

5. Enter the following information:

■ Number of IP addresses

■ Name of managing server

■ Starting IP address

■ Configuration macro to be used for configuring the clients

■ Lease type

Your summary page should look similar to the following example:

Chapter A Configuring a DHCP Server 83

6. Verify your configuration information and click Finish.

The DHCP Manager displays the following:

7. In the Address Properties window, do the following:

a. In each Client ID field, enter 01 followed by the MAC address that is

printed on the back of the RAID controller. For example:

0100A0E80F924C

b. Toward the bottom of the window, select “Assign only to BOOTP clients.”
