1-4 HP Smart Array 5300 Controller User Guide

Board Components and Features

Overview of Array Accelerator Features

The array accelerator is a high performance, battery-backed, 100-MHz SDRAM

DIMM cache module.

Array controllers use cache to store read data from the hard drives. The system can

later access this read data. The controller firmware uses the read-ahead and most

recently used caching algorithms.

Array controllers also use cache to complete drive write operations more quickly.

This use of the cache has further performance benefits:

• If the system requires data that still resides in write cache, the controller delivers this data from the cache. This process is quicker than delivering the data from a drive.

• If the system writes new data to the same location, the controller overwrites the cache contents. This eliminates a drive write operation.

• If the system performs a RAID 1 procedure, the controller gets mirrored data from the cache instead of from host memory.

• If the system performs a RAID 5 procedure, the write cache collects enough data blocks from several write accesses to carry out a full stripe write to the hard drives. This operation eliminates the need to calculate and update parity information each time that a data block is written to the drive.

With a battery-backed cache available, the array controller can complete the following operations more rapidly:

• Array capacity expansion—the expansion of a logical drive volume to include more hard drives

• Stripe size migration—the adjustment of the size of data blocks within a stripe, done to improve performance

• RAID level migration—the adjustment of RAID level to improve the fault tolerance of the array

HP Smart Array 5300 Controller User Guide 1-5

Board Components and Features

For each of these operations, data has to be reorganized among hard drives, and must be saved to non-volatile storage during the operation. (For further details of these operations, refer to Chapter 7, Appendix D, and Appendix E.) Without batterybacked cache, the data can only be stored at empty locations within the drive array, so these operations cannot occur at all if the array is full.

If the array controller or server fails before cached data can be stored on the array, the array accelerator and its integrated batteries may be removed from one array controller and installed on another controller of the same type. Any data in the array accelerator that has not been written to the hard drive will be transferred to the other array controller.

Other features of the array accelerator include:

• Cache capacity of 96-MB or 224-MB (32 MB of the cache is used for transfer buffer)

• Adjustable read/write ratio (usually set during array configuration as described in Chapter 7, but can be changed at any time)

• Error checking and correcting (ECC) memory, providing single-bit data correction

Sometimes, the Automatic Performance Tuning feature disables the array accelerator. You can also disable the array accelerator manually through the Array Configuration Utility (refer to Chapter 7 for details).

Batteries

The array accelerator cache has two rechargeable and replaceable NiMH battery packs. If the array accelerator is removed from the array controller, the battery packs maintain any cached data on the array accelerator for up to four continuous days.

1-6 HP Smart Array 5300 Controller User Guide

Board Components and Features

Figure 1-5: Battery packs

This data protection (and the time limit) also applies if an equipment failure or power outage occurs. When power is restored to the system, an initialization process writes the preserved data to the hard drives.

The batteries are continuously recharged using a trickle-charging process whenever the system power is on. Under normal operating conditions, a battery pack lasts for three years before replacement is necessary.

IMPORTANT: The batteries on a new array controller may have a low charge when the controller board is first installed. In this case, a Power-On Self-Test (POST) message 1794 is displayed when the server is powered up (refer to Appendix G), indicating that the array accelerator is temporarily disabled. No action is required on your part, since the internal circuitry automatically recharges the batteries and enables the cache. The recharge process takes less than four hours. The array controller will function properly during this time, although without the performance advantage of the array accelerator. When the batteries are charged to an acceptable capacity, the array accelerator is automatically enabled.

For battery replacement instructions, refer to Chapter 9.

HP Smart Array 5300 Controller User Guide 1-7

Board Components and Features

PCI System Interface

Smart Array 5300 controllers interface to the server through a high-performance 64-bit PCI bus that:

• Runs at 66 MHz

• Provides a high-speed path (up to 528 MB/s) between the system board and the

controller

• Includes two parity protection signals

The Smart Array 5300 Controller is a PCI Bus Master device conforming to Rev. 2.2 of the PCI Local Bus Specification. As a bus master device, it takes control of the PCI bus during high-speed transfers, freeing the system processor to handle application processing or other types of tasks.

For maximum performance, HP recommends that you use only 66-MHz devices on any given 66-MHz PCI bus. Combining 66-MHz and 33-MHz devices on a PCI bus will decrease the overall bandwidth to 33-MHz speeds.

SCSI Support

The Smart Array 5300 Controller supports drives that conform to Wide Ultra3 and Wide Ultra2 standards. Although Wide Ultra2 devices operate at a different maximum speed from Wide Ultra3 devices, operating speeds are unaffected if they are connected to the same SCSI bus because they both use low voltage differential (LVD) signaling.

Fault Management Features

The array controller and the network operating system support several fault management and data reliability features that minimize the impact of hard drive defects on your system.

1-8 HP Smart Array 5300 Controller User Guide

Board Components and Features

• Auto-Reliability Monitoring (ARM) is a background process that scans hard

drives for bad sectors in fault-tolerant logical drives. ARM also verifies the consistency of parity data in logical drives that are using RAID 5 or RAID ADG. This process assures that you can recover all data successfully if a drive failure occurs in the future. ARM operates only when you select a fault-tolerant configuration (RAID 1 or higher).

• Dynamic sector repair by the controller automatically remaps any sectors that

have media faults (detected either during normal operation or by auto reliability monitoring).

• S.M.A.R.T. is an industry-standard diagnostic and failure-prediction feature of

hard drives, developed in collaboration with the hard drive industry. It monitors several factors that can be used to predict imminent hard drive failure due to mechanical causes. Such factors include the condition of the read/write head, the seek error rate, and the spin-up time. When a threshold value is exceeded for one of these factors, the drive sends an alert that failure is imminent. Thus, the user can back up data and replace the drive before drive failure occurs.

NOTE: An online spare does not become active and start rebuilding when the imminent failure alert is sent, because the degraded drive has not actually failed yet and is still online. The online spare is activated only after a drive in the array has failed.

• Drive failure alert features cause an alert message to be displayed on the

system monitor when drive failure occurs. Different server models use different messages for different situations. These messages are described in your server documentation.

• Interim data recovery occurs if a drive fails in fault-tolerant configurations

(RAID 1 or higher). In this situation, the system will still process I/O requests, but at a reduced performance level. Replace the failed drive as soon as possible to restore performance and full fault tolerance for that logical drive. Otherwise, if another hard drive fails before data has been rebuilt, the logical volume will fail and data will be lost. Refer to Appendix E for more information about recovering from drive failure.

• POST or the Array Diagnostics Utility will also reveal imminent drive failure.

HP Smart Array 5300 Controller User Guide 1-9

Board Components and Features

• Recovery ROM is a redundancy feature that ensures continuous system availability by providing a backup ROM. This feature protects against corruption of a ROM image (caused, for example, by power fluctuation during ROM upgrade). If corruption occurs, the server automatically restarts using the remaining good copy of the ROM image.

When you upgrade the ROM, the inactive image (the one not being used by the system) is upgraded. There is not normally any noticeable difference in operation. When you use Recovery ROM for the first time, however, both ROM images are upgraded, causing a boot delay of about 60 seconds.

Other options, such as Insight Manager, provide additional drive failure features. Refer to your authorized reseller for more information about these products.

Figure 2-2: Controller installation in an already configured system

2-2 HP Smart Array 5300 Controller User Guide

Preparing the Server

Before installing the controller in the server, back up all data. This step is mandatory if you are moving non-arrayed SCSI drives to a Smart Array controller, because data is not preserved during a move between array controllers and non-array controllers.

WARNING: To reduce the risk of personal injury or damage to the equipment, consult the safety information and user documentation provided with your computer before attempting the installation.

Many computers are capable of producing energy levels that are considered hazardous. These computers are intended to be serviced by qualified personnel trained to deal with those hazards. Do not remove enclosures or attempt to bypass any interlocks that may be provided for the purpose of removing these hazardous conditions.

Installing the Hardware

If your server supports hot-pluggable devices, go directly to the section, “Installing the Smart Array Controller.”

To prepare a server that does not support hot-pluggable devices:

1. Close all applications.

2. Power down the server.

CAUTION: In systems using external data storage, be sure that the server is the first unit powered down and the last unit to be powered back up. Doing this ensures that the system will not erroneously mark the drives as “failed.”

3. Power down any peripheral devices that are attached to the server.

HP Smart Array 5300 Controller User Guide 3-1

Installing the Hardware

4. Unplug the AC power cord from the outlet, and then from the server.

IMPORTANT: If you will be replacing a Smart controller with a Smart Array controller, see the “External Cabling for HP Servers” section to determine the external cabling requirements.

5. Disconnect any peripheral devices from the server.

WARNING: To reduce the risk of personal injury from hot surfaces, allow the internal system components and hot-plug hard drives to cool before touching them.

CAUTION: Electrostatic discharge (ESD) can damage electronic components.

Be sure that you are properly grounded before continuing the installation procedure. See Appendix B for ESD information.

Installing the Smart Array Controller

1. Remove or open the access panel.

2. Select an available 66-MHz PCI slot. Slots that use a 64-bit interface may

provide higher performance.

3. Remove the slot cover or open the hot-plug latch. Save the retaining screw, if one is present.

4. Slide the controller board along the slot alignment guide.

3-2 HP Smart Array 5300 Controller User Guide

Installing the Hardware

Figure 3-1: Installing a Smart Array 5300 Controller

NOTE: Your server may look slightly different from the one illustrated.

5. Press the controller board firmly into the slot so that the contacts on the board

edge are properly seated in the system board connector.

6. Secure the board in place with the hot-plug latch or retaining screw.

7. Continue by following the instructions given in “Connecting the Cables.”

Connecting the Cables

Each port on the controller supports up to 14 drives. Ports 1 and 2 each have two SCSI connectors, one for external storage units and one for internal hard drives in the server. The two connectors for a given port cannot be used simultaneously. Ports 3 and 4 (present on the 5304 model, and also on the 5302 model with an attached 2- to 4-channel adapter) are only for external storage units.

Peripherals attached to any of the connectors must have a unique SCSI ID value in the range of 0 to 15 (except ID 7, which is reserved for controller use). The SCSI ID value determines the priority given to the device when it attempts to use the SCSI bus.

HP Smart Array 5300 Controller User Guide 3-3

Installing the Hardware

On HP and Compaq-branded products that support hot-pluggable drives, the SCSI IDs for peripherals are automatically set. For non-hot-pluggable devices, the IDs must be set manually by using switches or jumpers on the device itself.

IMPORTANT: When replacing an existing Smart controller with a Smart Array controller without reconfiguring the arrays, all of the drives should be connected exactly as they were on the old controller (port 1 to port 1, controller 1 to controller 1, and so on).

SCSI buses require termination on both ends to prevent signal degradation. In HP and Compaq-branded servers and storage systems, however, the controller, SCSI cable, and backplane already provide this termination.

Internal Cabling for HP Servers

1. If the device is not hot pluggable, power down the system.

2. Install drives into the removable media bays on the server. Drives that are to be

grouped in the same array should have the same capacity.

For detailed drive installation instructions, consult the documentation that accompanied your drives.

The exact procedure from this point depends upon whether the device is hot pluggable.

— If the drives are hot pluggable, go to step 3.

— If the drives are not hot pluggable, go to step 4.

3. Attach the internal point-to-point SCSI cable (provided with your server) from an internal port of the controller to the hot-plug drive cage.

For duplex drive cage options, use both internal ports.

The hot-pluggable drives are now ready to use.

4. For each SCSI bus, manually set the SCSI ID on each drive to a unique value in the range of 0 to 15, except 7 (which is reserved for controller use). For detailed instructions, consult the documentation that is provided with the drive.

5. Attach the multi-device SCSI cable from the internal port 1 or port 2 of the Smart Array controller to the non-hot-pluggable hard drives.

3-4 HP Smart Array 5300 Controller User Guide

The multi-device cable may have been provided with your server. If you need additional cables, order the cable option kit, Part Number 166389-B21. This cable is equipped to terminate either Wide Ultra3 or Wide Ultra2 drives.

CAUTION: Cable assembly 148785-001 is included in option kit 166389-B21 and is required with Wide Ultra3 drives. Failure to use this cable may result in reduced performance and/or data loss.

For additional information about drive installation, see Appendix E.

External Cabling for HP Servers

All HP and Compaq-branded Storage Enclosure models include external SCSI cables. Check the connector type on your storage device to identify the cable type needed. See Figure 3-2 and Table 3-1 for details.

Up to four SCSI ports may be available for connection to external storage devices depending on whether the 2- to 4-channel adapter is attached and whether internal drives are connected to the array controller.

1. On the rear of the server, connect the cable to the VHDCI connector on the Smart Array controller, and then tighten the lock screws on the cable connector.

IMPORTANT: Offset VHDCI cables must be used with the Smart Array 5300 controller. Early versions of the VHDCI cables do not accommodate side-by-side connection of the cables to the Smart Array 5300 controller. If your storage enclosure did not include the Offset VHDCI cables, you may need to order these. See Table 4-1 for part numbers.

NOTE: Do not use a port externally if it is already being used internally.

2. Attach the other end of the cable to the storage enclosure, and then tighten the lock screws on the cable connector.

3. Replace the access panel and secure it with the thumbscrews, as required.

CAUTION: Do not operate the server with the access panel removed for extended periods of time. This precaution is to protect thermally sensitive components by ensuring the proper airflow through the server, and also to minimize personal contact with hazardous energy levels.

Updating the System Firmware

To update the system firmware, the System ROMPaq utility is used.

NOTE: This utility is not to be confused with the Options ROMPaq utility (refer to Chapter 5), which is used to update the firmware on server options and SCSI drives.

This utility has two main sources:

• The SmartStart CD that is either shipped with your server or available directly

from HP

• The downloadable SoftPaq file on the HP website

If your server has a bootable CD-ROM drive, you can run System ROMPaq directly from the CD. Otherwise, you must run System ROMPaq from a diskette created from either the CD or from the SoftPaq file.

IMPORTANT: Compare the version numbers of the System ROMPaq utility from these two sources. If the CD version is older, use the SoftPaq file instead.

Running System ROMPaq from the CD

1. Boot the server from the SmartStart CD.

2. On the System Utilities screen, select Run ROMPaq.

HP Smart Array 5300 Controller User Guide 4-3

Updating the Controller Firmware

You can update the firmware on HP and Compaq-branded options by using the Options ROMPaq utility. There are two versions of this utility: Options ROMPaq for Array Controllers, and Options ROMPaq for Internal (SCSI Attached) Drives.

If you purchased your server with an array controller already installed, you do not need to run this utility during server installation. However, if you have older Smart Array Controllers or other HP or Compaq-branded options (such as drives), run Options ROMPaq to make sure that these devices have the latest firmware. HP recommends that you run the latest Options ROMPaq on all HP or Compaq-branded array controllers whenever new versions of the utility are released.

The Options ROMPaq utility has three main sources:

• The SmartStart CD

• The Smart Array Controller Support Software CD

• The downloadable SoftPaq file on the HP website

If your server has a bootable CD-ROM drive, you can run Options ROMPaq directly from the CD. Otherwise, you must run Options ROMPaq from a diskette created from the CD or from the SoftPaq file.

IMPORTANT: Compare the version numbers of the Options ROMPaq utility from these sources. If the CD version is older, use the SoftPaq file instead.

HP Smart Array 5300 Controller User Guide 5-5

Updating the Controller Firmware

Updating the System Partition

If you are installing the controller on a server that was previously configured with SCU, you must now use this utility to update the system partition.

NOTE: If your server uses the ROM-Based Setup Utility (RBSU), you do not need to run SCU.

SCU is provided on both the SmartStart CD and the Smart Array Controller Support Software CD. Compare the SCU version numbers from these two sources and use the most recent version.

NOTE: Before updating Novell NetWare volumes or partitions, remember these tips to optimize system performance:

• If you want to use hardware-based RAID, do not select mirroring while using

INSTALL.NLM or NWCONFIG.NLM.

• Novell recommends that you create volumes with a 64-kbyte block size to decrease the

amount of RAM required to mount the volume, and use the Block Sub-Allocation feature to allow disk space to be allocated more efficiently.

• Linear memory provides the best system performance in the NetWare environment. If you

previously used SCU to configure your server, this option would have been the default. To check that the system is using linear memory, run SCU and view the Memory settings. Confirm that a linear option is selected under the Base Memory option.

1. Restart the server from the CD.

2. If the CD-ROM drive is bootable, go to step 5. Otherwise, locate the CD-ROM

drive:\SYSCFDSK\US directory, run the file QRST5.EXE, and follow the onscreen instructions to create four SCU diskettes.

3. Insert SCU diskette #1 into the server diskette drive.

4. Restart the system.

5. Select System Configuration Utility from the menu or list of icons that is

displayed.

6. Follow the on-screen instructions to update or create and populate a system partition.

7. Exit from SCU. If the server does not reboot or a CD error message is displayed, press the Ctrl+Alt+Del keys to continue and reboot the server.

5-6 HP Smart Array 5300 Controller User Guide

After installing the controller hardware and updating the controller firmware:

• Configure the system by using either the ROM-Based Setup Utility (RBSU) or

the System Configuration Utility (SCU), following the procedure given in the server user guide.

• Set the boot controller by using RBSU or the Option ROM Configuration for

Arrays (ORCA) utility (described in this chapter).

• Create at least one logical drive by using ORCA or ACU (as described in

Chapter 7).

Using RBSU

RBSU is a system configuration utility that is embedded in the system ROM, and is customized for the server that it is installed on. Update RBSU when necessary by using System ROMPaq.

CAUTION: Not all servers support RBSU. Do not flash an RBSU-ROM image onto a server that is already configured with SCU unless the update instructions specifically state that upgrading from SCU to RBSU is supported. If the upgrade is not supported, the consequences of upgrading are unpredictable and you may lose data.

Setting the Controller Order

HP Smart Array 5300 Controller User Guide 6-1

Setting the Controller Order

To use RBSU:

1. Power up the server.

2. Press the F9 key when prompted during system startup.

5. When you have finished using the utility, press the Esc key, and then press the F10 key to confirm that you want to exit RBSU.

Using ORCA

Part of the startup sequence of a server is the Power-On Self-Test (POST). If the array controller in the server supports ORCA, POST temporarily halts and an ORCA prompt message is displayed for about five seconds. (If ORCA is not supported, the prompt message is not displayed and the system continues with the startup sequence.)

1. Power up the server and let the system startup sequence begin.

2. While the prompt message is on the screen, press the F8 key to start ORCA.

HP Smart Array 5300 Controller User Guide 6-3

Configuring an Array

HP provides four utilities for configuring an array:

• Option ROM Configuration for Arrays (ORCA)—a simple ROM-based

configuration utility that runs on all operating systems

• Array Configuration Utility (ACU)—a versatile configuration utility that

provides maximum control over configuration parameters

• Array Configuration Utility 6.0 (ACU 6.0)—a browser-based version of ACU

• NetWare Online Array Configuration Utility (CPQONLIN)—a menu-driven

utility for NetWare

The following limitations apply to all configuration methods:

• For the most efficient use of drive space, do not mix drives of different capacity

within the same array. Each configuration utility treats all physical drives in an array as if they have the same capacity as the smallest drive in the array. Excess capacity of larger drives is wasted because it is unavailable for data storage.

• The probability that an array will experience a hard drive failure increases with

the number of hard drives in the array (for more detailed information, refer to Appendix F). If you configure an array with RAID 5, keep the probability of failure acceptably low by using no more than 14 drives.

This chapter describes how to use ORCA, ACU, and CPQONLIN. For detailed information about using ACU 6.0, refer to the HP Array Configuration Utility 6.0 User Guide. For background information about drive arrays and fault-tolerance (RAID) methods, refer to Appendix D.

Using ORCA

When a computer system is powered up, part of the startup sequence is the Power-On Self-Test (POST). Any array controllers that are in the system are initialized while POST is running. If the array controller supports ORCA, POST temporarily halts and an ORCA prompt message is displayed for about five seconds. (If ORCA is not supported, the prompt message is not displayed and the system continues with the startup sequence.)

While the prompt is displayed, press the F8 key to start ORCA. The ORCA main menu is displayed, allowing you to select the boot controller for the system, or to create, view, or delete a logical drive.

You can now create another logical drive by repeating the previous steps.

NOTE: Raw logical drives are invisible to the operating system. To make the new logical drives available for data storage, format the logical drive using the instructions given in your operating system documentation.

Using ACU

The Array Configuration Utility is located on the Smart Array Controller Support Software CD and on the SmartStart CD. You can run ACU directly from one of these CDs, or—if the server you are configuring is running the Microsoft Windows NT or Windows 2000 operating system—you can download ACU onto your server and run it online.

When you start ACU, it checks the configuration of every controller and drive array. If an array is not configured optimally, the ACU configuration wizard opens and guides you through the configuration process. The wizard also helps you to configure any new controllers, assign unused physical drives to existing arrays (without destroying data), and configure any unused space present on an array into another logical drive. ACU allows you to create up to 32 logical drives per array.

If a problem arises during the configuration process, ACU displays an error message describing the problem. If the following warning message is displayed along with an error code number, call your local HP technical support number for assistance:

Internal Error Has Occurred

For technical support phone numbers, refer to the “About This Guide” section.

Secondary Screens

Controller Settings Screen

To display this screen, click Settings in the Controller box (Figure 7-6) on the main ACU screen.

This screen allows you to set the rebuild priority, expand priority, and accelerator read/write ratio.

Figure 7-9: Controller Settings screen

The settings that you select for Rebuild Priority and Expand Priority will not affect the performance of an idle system. However, they will affect performance on a busy system:

• On the High settings, the controller will give preference to the rebuild or expansion process over normal I/O operations.

• On the Low settings, the controller will rebuild or expand only when the controller is idle. However, this setting leaves the array vulnerable to drive failure for a longer time than the High setting.

The Accelerator Ratio settings determine the amount of memory allocated to the read and write caches. Some applications may perform better with a larger write cache; others may perform better with a larger read cache. If your controller does not have a battery-backed array accelerator, only read cache will be available (the ratio will always be 100% Read / 0% Write).

(RAID overhead is not needed for RAID 0.)

The default logical drive size first shown in this box is the maximum available for your drive array. To create more than one logical drive on the array, reduce the logical drive size by typing a smaller number in the scroll box. ACU allows you to create up to 32 logical drives per array.

Use larger stripe sizes for best performance

Use smaller stripes for RAID 5

Click Advanced to display the Create Logical Drive – Advanced Features screen, where you can enable or disable the maximum boot size for a logical drive. The default boot size is 32 sectors (16 kbytes) per track, and the maximum boot size is 63 sectors per track.

Figure 7-12: Create Logical Drive – Advanced Features screen

7-14 HP Smart Array 5300 Controller User Guide

Configuring an Array

Some operating systems need to use the maximum boot size to be able to create large boot partitions. For example, enabling the maximum boot size on a logical drive in the Windows NT 4.0 operating system allows you to create a bootable partition with a maximum size of 8 GB.

NOTE: Enabling the maximum boot size may decrease performance of the logical drive.

Modify Logical Drive Screen

Typical Manual Configuration Procedures in ACU

When you launch ACU to configure a new array, a configuration wizard opens to allow rapid, automatic array configuration. However, you can bypass the wizard and manually:

• Create a new array.

• Expand the capacity of an array.

• Extend the capacity of a logical drive.

• Migrate to a different RAID level or stripe size.

Creating a New Array

There are three stages in the procedure for manually creating a new array:

1. Configure the controller settings.

2. Assign physical drives of the same size to an array.

7-16 HP Smart Array 5300 Controller User Guide

Configuring an Array

3. Create one or more logical drives on the array.

For this example, assume that you have ten 9.1-GB drives connected to your controller. You want to make two arrays:

• Array A: seven 9.1-GB drives with a spare, configured with RAID 5 fault

tolerance

• Array B: two 9.1-GB drives in a RAID 1+0 fault-tolerance configuration

Configuring the Controller Settings

1. On the main ACU screen, select the controller to be used from the drop-down list

in the Controller Selection box. (Alternatively, click Controller on the menu bar, and then click Select.)

2. Click Controller Settings.

The Controller Settings screen is displayed (Figure 7-9).

3. Select the rebuild priority, expand priority, and accelerator ratio.

4. Click Done to return to the main ACU screen.

Assigning Physical Drives of the Same Size to an Array

1. Click Create Array in the Controller box.

The Create Drive Array screen is displayed (Figure 7-10).

2. Select the drives that are to constitute the array from the drive list in the left

panel.

— Do not assign a group of physical drives to the same array unless they are of

the same capacity. If the drives have different capacities, the excess capacity of the larger drives cannot be used by the array and is wasted.

— The probability that an array will experience a drive failure increases with

the number of drives in the array. HP recommends that no more than 14 drives be used per array in RAID 5 configurations.

For this example, select the seven drives on Port 1 with SCSI IDs 0 through 6.

HP Smart Array 5300 Controller User Guide 7-17

Configuring an Array

3. Click the Assign Drive to Array button (Figure 7-15) in the middle of the screen.

Figure 7-15: Assign Drive to Array button

4. Select the drive at Port 1: SCSI ID 7 and click the Assign Spare to Array button in the lower middle part of the screen.

NOTE: You can share any given spare among several arrays. You can also assign several spares to just one array, or share one group of spares among several arrays. In all such cases, be sure that the capacity of each spare is large enough for each array that it is assigned to. (The capacity of a spare must be no less than that of any other drives in the same array.)

The Create Drive Array screen now looks like Figure 7-16.

Figure 7-16: Example Array A with Spare

5. Click Done to return to the main ACU screen.

7-18 HP Smart Array 5300 Controller User Guide

Configuring an Array

The Logical Configuration View window now looks like Figure 7-17.

Figure 7-17: Logical Configuration View of Example Array

6. Select the controller icon, and then click Create Array to create Array B.

7. Repeat the previous steps to assign both remaining 9.1-GB drives to array B.

8. Click Done to return to the main ACU screen.

In this example, each array was created using drives from the same SCSI port. You can get better performance by installing the correct capacity drives in other ports before running the ACU, and then selecting drives from more than one port to build the array.

Creating One or More Logical Drives on the Array

1. Select the Array A icon or the Unused Space icon under Array A in the Logical

Configuration View window (Figure 7-17).

2. Click Create Logical Drive in the Array box.

3. On the Create Logical Drive screen (Figure 7-11), select RAID 5.

4. Select Enable, if this radio button is active.

5. Change the stripe size, if desired (and if possible for your controller model).

6. The default values in the Logical Drive Size box create a single logical drive on

the array. For this example, accept the default values.

7. Click Done to return to the main ACU screen.

8. Save the new settings by clicking Controller on the menu bar and selecting Save

Configuration.

HP Smart Array 5300 Controller User Guide 7-19

Configuring an Array

9. Create a logical drive on Array B:

a. Select the Array B icon or the Unused Space icon under Array B in the

Logical Configuration View window.

b. Repeat steps 2 through 7. This time, select RAID 1+0 as the fault-tolerance

method in step 3.

c. Save the configuration, as in step 8.

The main ACU screen now looks like Figure 7-18.

Figure 7-18: Example configuration with two arrays

NOTE: The capacity shown for each logical drive is the free capacity available for data

storage. This value excludes the amount used for fault tolerance.

Expanding Array Capacity

Array capacity expansion is the addition of storage capacity to a pre-existing array. The capacity of logical drives on the array does not change, and existing data is not changed.

7-20 HP Smart Array 5300 Controller User Guide

Configuring an Array

During capacity expansion, ACU automatically redistributes existing logical drives across all of the physical drives in the expanded array. If the array being expanded has more than one logical drive, data is redistributed one logical drive at a time. Newly created logical drives are not available until capacity expansion has finished.

CAUTION: Do not exchange the controller or array accelerator board during array capacity expansion. Interrupting expansion in this way causes irretrievable data loss.

NOTE: The expansion process takes about 15 minutes per gigabyte. Data can still be read from or written to any logical drive on the controller during an expansion, although performance might be reduced. However, a controller can perform only one expansion, extension, or migration at any given time.

There are three stages in the procedure for expanding an array:

1. Back up all data on the array. Although array expansion is unlikely to cause data

loss, observing this precaution will provide additional data protection.

2. Install the new physical drives. The capacity of each new drive must be no less

than that of the drives that are currently in the array.

IMPORTANT: Do not assign a group of physical drives to the same array unless they are of the same capacity. If the drives have different capacities, the excess capacity of the larger drives cannot be used by the array and is wasted.

3. Assign the new physical drives to an existing array. When the expansion process

is complete, the extra capacity can be used to increase the size of an existing logical drive (refer to the “Extending Logical Drive Capacity” section) or to create a new logical drive.

For example, consider a controller with the two arrays that were made in the example given in the “Creating a New Array” section:

• Array A—seven 9.1-GB drives in a RAID 5 configuration with a spare

• Array B—two 9.1-GB drives in a RAID 1+0 configuration without a spare

HP Smart Array 5300 Controller User Guide 7-21

Configuring an Array

Now you install a 9.1-GB drive, and want to expand Array A to include this new drive. This scenario is represented in Figure 7-19.

Figure 7-19: Starting an array expansion

To expand Array A and create a second logical drive on this array:

1. Select Array A in the Logical Configuration View window.

2. Click Expand in the Array box.

3. In the left-hand panel of the Expand Array A window, select the unassigned

9.1-GB drive.

4. Click the button in the middle of the screen (Assign Drive to Array).

5. Click Next. The screen shown in Figure 7-20 is displayed.

7-22 HP Smart Array 5300 Controller User Guide

Configuring an Array

Figure 7-20: Create Logical Drives screen

6. Click Create Logical Drive.

7. Set the fault tolerance, stripe size, array accelerator, and size for the second

logical drive that you want to create on Array A.

8. Click Done to return to the Create Logical Drives screen.

9. Click Done again to return to the main ACU screen.

10. On the menu bar, select Controller, Save Configuration. The settings for the

new logical drive are saved and the capacity expansion process begins.

NOTE: The new logical drive is not built until after the controller has finished the capacity expansion process on Array A. This takes about 15 minutes per gigabyte. Data can still be read from or written to any other existing logical drive on the controller, although performance might be reduced. However, a controller can perform only one expansion, extension, or migration at any given time.

Extending Logical Drive Capacity

Logical drive capacity extension is the addition of storage capacity to an existing logical drive. For logical drive extension to be possible, sufficient free capacity must exist on the array. If necessary, create free capacity by deleting existing logical drives on the array or by performing an array expansion (for details, refer to “Expanding Array Capacity”).

HP Smart Array 5300 Controller User Guide 7-23

Configuring an Array

The Windows NT 4.0 operating system supports online logical drive capacity extension. Some operating systems also support offline capacity extension. Before extending logical drives, check the operating system documentation for current information, or contact your operating system vendor.

NOTE: The extension process takes about 15 minutes per gigabyte. Data can still be read from or written to any logical drive on the controller during an extension, although performance might be reduced. However, a controller can perform only one expansion, extension, or migration at any given time.

To extend the capacity of a logical drive:

1. Back up all data on the array. Although array expansion is unlikely to cause data loss, observing this precaution will provide additional data protection.

2. If you are extending the capacity while offline:

a. Restart the server from the software CD provided in the controller kit.

b. Open ACU from the CD.

3. Select the logical drive in the Logical Configuration View window.

4. Click Extend in the Logical Drive box.

The Extend Logical Drive screen displays the current capacity and overhead of the selected logical drive. The unshaded region on the slider scale shows the free capacity on the array that is available for extension.

5. Move the slider control to increase the size of the logical drive.

NOTE: You cannot reduce the size of the logical drive from this screen.

6. Click Done to return to the main ACU screen.

7. To save the logical drive settings, click Controller on the menu bar and select

Save Configuration.

A progress bar in the lower right-hand corner of the screen shows the status of the extension process.

7-24 HP Smart Array 5300 Controller User Guide

8. Make the extra capacity of the logical drive available to the operating system by

one of the following methods:

— Create a new partition in the logical drive by using the operating system

partitioning software.

— Increase the size of an existing partition by using the operating system

partitioning software or third-party partitioning tools.

Migrating RAID Level or Stripe Size

NOTE: Before migrating the stripe size, check that the memory available to the array

accelerator is no smaller than the lowest common multiple of the total stripe sizes of the two different configurations.

For example, consider the change from an 11-drive RAID 5 logical volume to a 14-drive RAID 1+0 logical volume. If each configuration uses the corresponding default stripe width, the block size changes from 16 kbytes per stripe to 128 kbytes per stripe.

• A full stripe in the RAID 5 configuration contains 160 kbytes (ten of the drives contain user

data; one drive contains parity data).

• A full stripe in the RAID 1+0 configuration contains 896 kbytes.

The lowest common multiple of the two stripe sizes is 4480 kbytes, and this figure represents the minimum amount of memory that must be available to the array accelerator.

Configuring an Array

To migrate to a different RAID level or stripe size:

1. Back up all data on the logical drive. Although migration is unlikely to cause

data loss, observing this precaution provides extra security. The backup data may also be needed if the number of sectors needs to be increased (this fact will be determined in step 8).

2. Check that the array accelerator batteries (if present) are fully charged.

NOTE: The migration process takes about 15 minutes per gigabyte. Data can still be read from or written to any logical drive on the controller during a migration, although performance might be reduced. However, a controller can perform only one expansion, extension, or migration at any given time.

3. If your controller has a battery-backed write cache, check the Controller

Settings screen in ACU to confirm that the write cache is enabled.

4. Select the logical drive in the Logical Configuration View window.

HP Smart Array 5300 Controller User Guide 7-25

Configuring an Array

5. Click Migrate in the Logical Drive box.

6. Change the RAID level by selecting the appropriate check box.

7. Change the stripe size (Table 7-3 gives the optimum stripe size for specific

situations).

8. Click Done to return to the main ACU screen.

If you get a message stating that the number of sectors needs to be increased:

a. Delete the old logical volume.

b. Reconfigure the array as a new logical volume with the new fault-tolerance

method and stripe size that you had selected.

c. Copy the backed-up data (from step 1) into the new logical volume.

9. To save the new settings, click Controller on the menu bar and select Save

Configuration.

Using CPQONLIN

HP Smart Array 5300 Controller User Guide 7-31

Configuring an Array

Adding Spare Drives

To add spare drives to an array, the array controller must have at least one attached drive that is either unassigned or is assigned as a spare to another array.

You can:

• Assign a different online spare to each array on the controller.

• Share one online spare among several arrays on the same controller, for efficient

use of drive capacity.

• Assign several online spares to just one array.

• Share several online spares among several arrays; this method provides the

greatest amount of protection for the largest number of arrays.

IMPORTANT: Assigning several spares to an array lets you postpone replacement of faulty drives, but it does not increase the fault-tolerance level of any logical drives in the array. For example, a logical drive in a RAID 5 configuration suffers irretrievable data loss if two physical drives fail simultaneously, regardless of the number of spare drives assigned.

Any drive that you assign as an online spare for an array operates as the spare for every fault-tolerant logical drive within the array.

When you select Assign Spare, only drives that qualify will be displayed; for example, drives with too small a capacity are not listed. If a drive that you expect to see is not listed, press the Tab key (to switch to the physical drive view) and check the capacity of the drive.

To add a spare:

1. In the Logical Configuration View panel, highlight the array that needs a spare, and then press the Enter key.

2. Choose Assign Spare in the Array Options menu, and then press the Enter key.

3. Select the drive that you want as the spare, and then press the Enter key.

4. Choose Stripe Size and then press the Enter key.

5. Choose the stripe size that you want and then press the Enter key.

6. Press the Esc key to accept the settings and return to the main manual

configuration screen.

Configuring the Controller Settings

The Controller Settings option allows you to choose the drive rebuild priority, expansion priority, and accelerator ratio for all arrays on the controller.

• With a low priority setting, a rebuild or expansion takes place only when the

array controller is not busy handling normal I/O requests. This setting has minimal effect on normal I/O operations. However, there is an increased risk that data will be lost if another physical drive fails while the rebuild is in progress.

Configuring an Array

• With a high priority setting, the rebuild or expansion occurs at the expense of

normal I/O operations. Although performance is affected, this setting provides better data protection because the array is vulnerable to additional drive failures for a shorter time.

NOTE: Logical drives can be rebuilt only if they are configured for fault tolerance (RAID 1+0, RAID 5, or RAID ADG). Drive rebuild begins automatically after you have replaced a failed physical drive in the array.

The accelerator read/write ratio determines the amount of memory allocated to the read and write caches on the array accelerator. Different applications have different optimum settings. Some controllers (especially those without battery-backed write cache) do not allow this ratio to be changed.

HP Smart Array 5300 Controller User Guide 7-33

Configuring an Array

Enabling RAID ADG

You can enable RAID ADG on a Smart Array 5300 Controller by installing a software key. Alternatively, if you have an older version of the controller, you can install a hardware enabler module on the controller board.

Using the Software Key

1. Confirm that the array accelerator has a capacity of at least 64 MB.

2. Close all applications and utilities on the server containing the controller.

3. Insert the CD from the RAID ADG option software kit into the CD-ROM drive.

4. Reboot the server.

5. If necessary, upgrade the controller firmware to the version provided on the CD,

and then reboot the server. (This step is required, for example, if the controller is a Smart Array 5300 with a current firmware version less than 2.72.)

NOTE: If the firmware on the controller is newer than that on the CD, the flash utility does not replace it with the earlier firmware from the CD.

6. Select Array Configuration Utility 6.0 from the CD menu.

This action opens ACU 6.0, the browser-based version of the Array Configuration Utility (ACU).

IMPORTANT: Use the version of ACU 6.0 that is provided on the CD. The software key cannot be installed using versions of ACU 6.0 earlier than 1.40, nor can it be installed using ACU.

7. When the utility has loaded, select the controller that is to be used to configure RAID ADG.

8. Select License Key Management.

9. Select Enter License Key.

10. Enter the 25-character license key (provided on the CD sleeve) and click Submit.

If you wish, you can now configure the controller using ACU 6.0.

11. Exit ACU 6.0, remove the CD, and reboot the server.

For further instructions or clarifications regarding the software key installation procedure, refer to the ACU 6.0 online help.

Using the Enabler Module

The connector for the RAID ADG Enabler Module is located at the corner of the controller board near the array accelerator connector socket, as shown in Figure 9-14. The module attaches to the controller board with the narrow tab (circled in Figure 9-15) nearest to the corner of the controller board. This tab can be pressed outwards during installation to allow the module to be more readily inserted into the board. The clips at each end of the module fit into the slots on the board.

Federal Communications Commission Notice

Part 15 of the Federal Communications Commission (FCC) Rules and Regulations has established Radio Frequency (RF) emission limits to provide an interference-free radio frequency spectrum. Many electronic devices, including computers, generate RF energy incidental to their intended function and are, therefore, covered by these rules. These rules place computers and related peripheral devices into two classes, A and B, depending upon their intended installation. Class A devices are those that may reasonably be expected to be installed in a business or commercial environment. Class B devices are those that may reasonably be expected to be installed in a residential environment (for example, personal computers). The FCC requires devices in both classes to bear a label indicating the interference potential of the device as well as additional operating instructions for the user.

The rating label on the device shows the classification (A or B) of the equipment. Class B devices have an FCC logo or FCC ID on the label. Class A devices do not have an FCC logo or FCC ID on the label. After the Class of the device is determined, refer to the corresponding statement in the following sections.
