Battery-Backed Cache Module Overview

The battery-backed cache module is a high-performance, 100-MHz SDRAM DIMM read/write cache that increases performance in database and fault-tolerant configurations.

Caching Functions

To enable faster data access from disk storage, the cache module performs two types of caching:

• Posted-write caching—the controller writes user data in the cache memory on the module rather than directly to the drives. Later, when the system is idle, the controller writes the data to the drive array.

• Read-ahead caching—the controller detects sequential array access, reads ahead into the next sequence of data, and stores the data in the read-ahead cache. Then, if the next read access is for the cached data, the controller immediately loads the data into system memory, avoiding the latency of a disk access.

Batteries

The cache module has two rechargeable and replaceable NiMH battery packs that protect cached data during equipment failure or power outage:

• Up to 3 days protection for 256-MB cache DIMMs

• Up to for 4 days protection for 128-MB cache DIMMs

Under normal operating conditions, the battery packs should operate for 3 years before replacement is necessary. The batteries recharge continuously when the system is powered on.

NOTE: Temperature, age, and cache size may affect battery life.

The batteries also preserve data when you remove the cache module from the controller. After you reinstall the cache module, and power is restored, the initialization process writes the preserved data to the array. This feature is important for data stored in the posted-write cache, but not yet written to an array.

Controller Display

Each MSA500 array controller in the MSA500 system contains an integrated LCD display. This module displays informational and error messages, shows the current status of the module, and provides an interface for user input. The system combines traditional POST messages issued by PCI-based array controllers with runtime event notification messages for this new set of controller display messages. The display module consists of the following components:

• A two-line, 20-column display text window

• Four buttons

• Two LEDs

Types of Messages

The display module is capable of storing up to 100 messages. When the message log is full, the system deletes the oldest message to make room for the most recent one.

The types of messages include:

Installation and Operation

• Error Messages—Error messages indicate a problem that may require user action.

The Fault LED illuminates when you view an error message. It also illuminates to indicate that an unviewed error message is in the queue and was followed by other types of messages. When scrolling backwards to view all error messages, the LED illuminates only when an error message is in the text display window.

• Informational Messages—Informational messages provide feedback on non-critical changes.

• User Input Messages—User input messages indicate an issue that requires a choice. The user can choose a selection before the end of a time-out period or allow the controller to default to a standard choice. User input messages only occur during system power up.

The Fault LED flashes when a user input message is in the text display window and requires input. If the user does not provide input within the time-out period, the message remains, but the LED stops flashing.

HP StorageWorks Modular Smart Array 500 System User Guide 2-15

Installation and Operation

For a complete list of messages and their meanings, refer to Appendix C, “Display Messages.”

Using the Interface

• Scrolling—To view older messages, scroll backwards with the Up button (indicated by the up arrow). To view newer messages, scroll forwards with the Down button (indicated by the down arrow).

The arrival of new messages supersedes the display of any previous messages. When a new message arrives, the display ignores its previous scrolling position and presents the new message.

• Selecting User Input Options—User input messages present the user with a choice and define the options in the text display window. Select one of the options by pushing the left button (indicated by the left arrow) or the right button (indicated by the right arrow).

• Deleting Messages—To delete a message, scroll to the message, then press the left and right buttons simultaneously.

Hot-Plug SCSI Hard Drive Options

Observe the following guidelines when adding SCSI hard drives:

• If only one SCSI hard drive is used, install it in the bay with the lowest number.

• Hot-plug hard drives must be 1-inch universal SCSI types.

• Drives must be the same capacity to provide the greatest storage space efficiency

when drives are grouped together into the same drive array.

Removing Hard Drive Blanks

CAUTION: Always populate bays with either a component or blank. Proper airflow

can be maintained only when the bays are populated. Operating the system with unpopulated bays can lead to improper cooling and thermal damage.

To remove a hard drive blank:

To install a blank, align the blank with the empty bay and push the blank inward until it locks into place.

3-2 HP StorageWorks Modular Smart Array 500 System User Guide

Replacing Hot-Plug SCSI Hard Drives

CAUTION: If you must replace a hot-plug drive, follow the guidelines in this section.

Failure to do so can result in data loss and can void the warranty.

RAID 0 is not a fault-tolerant configuration. Never remove a drive from a RAID 0 array unless it has failed. Drive failure is indicated by an amber drive failure LED. In a RAID 0 configuration, removal of an operating drive results in data loss. To remove a drive without losing data, always back up the entire array, replace the drive, and restore the entire array. Backing up a single drive and replacing it does not restore the array.

Some instances exist in which you may replace a drive in RAID 1, 5, and ADG configurations. To determine when drive replacement is possible without data loss, use the hot-plug SCSI hard drive LEDs combination table in Chapter 1, “Component Identification.”

Follow these additional guidelines when replacing drives:

• Never remove more than one drive at a time (or two drives if you are using ADG). When you replace a drive, the controller uses data from the other drives

in the array to reconstruct data on the replacement drive. If you remove more than one drive, a complete data set is not available to reconstruct data on the replacement drive(s) and permanent data loss could occur.

Hardware Options Installation

• Never remove a drive while the controller is rebuilding another drive. Each drive has an online LED that flashes green while the drive is being rebuilt. The controller requires the data from all other drives to rebuild the replacement drive.

• If the system has an online spare drive, wait for it to complete rebuilding before replacing the failed drive. When a drive fails, the online spare becomes

active and begins rebuilding as a replacement drive. After the online spare has completed Automatic Data Recovery (the online LED is continuously lit), replace the failed drive with a new replacement drive. Do not replace the failed drive with the online spare. The system automatically rebuilds the replacement drive and resets the spare drive to an available state.

• If you replace a drive while the system is off, it may be necessary to rebuild the replaced drive.

HP StorageWorks Modular Smart Array 500 System User Guide 3-3

Hardware Options Installation

To replace a drive:

1. Be sure that the online and activity LEDs on the failed drive are both off.

2. Remove the failed drive.

3. Install the new replacement drive.

CAUTION: Data loss can occur if the drive is not firmly seated.

3-4 HP StorageWorks Modular Smart Array 500 System User Guide

4. Be sure that the drive LEDs illuminate one at a time and then turn off together to indicate that the system has recognized the new drive.

In fault-tolerant configurations, allow the replacement drive to be reconstructed automatically with data from the other drives. While reconstruction is in progress, the online LED flashes.

Universal Hot-Plug Tape Drive Option

HP StorageWorks Modular Smart Array 500 Controller Option

The system ships with one MSA500 controller. To provide redundancy and maximize storage system uptime, install a second Smart Array controller.

Observe the following guidelines:

• If a controller has more than one cache DIMM, be sure that both DIMMs have the same memory capacity.

• Always upgrade the cache in both controllers in a system with redundant controllers.

• In a system with a redundant controller, be sure that both controllers have the same number of DIMMs and that all DIMMs have the same memory capacity.

• To configure a MSA500 system for controller redundancy, both controllers must execute the same version of firmware. If the controllers have different firmware versions, the system responds as follows:

— In a hot-plug addition of the second controller, the system clones the

firmware version of the active controller onto the second controller. After the second controller is reset, the controllers become redundant.

— In a non-hot-plug addition of the second controller, the system examines the

firmware versions of both controllers at power up and clones the most recent version from one controller to the other controller.

For more information about upgrading firmware, refer to Chapter 4, “Configuration and Utilities.”

Server Utilities

HP utilities provide reporting functions that enable event-focused management and diagnostics. To install and run these utilities, refer to the server documentation.

• Diagnostics Utility—This utility tests and verifies proper operation of the system hardware. If problems are found, the utility isolates failure(s) down to the replaceable part, whenever possible. When an operating system is installed with SmartStart Version 5.30 or later, the Diagnostics and utilities are installed on a partition of the hard drive that contains the operating system. (This hard drive may or may not be located in the storage system.) Always access these utilities when a system configuration error is detected during POST.

• INSPECT Utility—This utility provides a report detailing system information.

• Insight Manager 7—This Web-based application enables system administrators

to accomplish normal administrative tasks from any remote location, using a Web browser. Insight Manager 7 provides device management capabilities that consolidate and integrate management data from HP and third-party devices.

Configuration and Utilities

• Insight Management Agents—These agents enable easy manageability of the server through Insight Manager 7 software and third-party SNMP management platforms. Management agents monitor key subsystems that are instrumental in making health, configuration, and performance data available to the agent software. The agents act upon that data by initiating alarms in the event of faults. The agents also provide updated management information, such as network interface or subsystem performance statistics, to the management systems.

HP StorageWorks Modular Smart Array 500 System User Guide 4-1

Configuration and Utilities

• Survey Utility—This utility gathers critical hardware and software information on servers running Microsoft Windows and Novell NetWare operating systems. If a significant change occurs between data-gathering intervals, the Survey Utility marks the previous information and overwrites the Survey text files to reflect the latest changes in the configuration.

Recovery Server Option

The HP ProLiant Essentials Recovery Server Option (RSO) software kit supports a standby recovery server configuration. This configuration comprises two identical (and identically configured) ProLiant servers connected to a common MSA500 system and a common network. One of the servers (the primary) supports network clients by default. The other server remains in a preboot stage during normal use and acts as a backup (recovery) server. All hard drive storage is located in the shared storage system. The storage system also contains a single copy of the operating system and all the applications, drivers, and data.

When a system fault occurs in either the server or operating system, RSO automatically takes the primary server offline and initializes the recovery server to take over operations. While the recovery server is supporting network clients, the primary server can be repaired at leisure.

For more information about configuring RSO, refer to the HP ProLiant Essentials Recovery Server Option User Guide that ships with the software.

For installation procedures, refer to the HP ProLiant Essentials Recovery Server Option Pack Installation Instructions that ships with the software.

ROM Functions and Utilities

Each MSA500 controller has a ROM that contains the controller firmware.

Recovery ROM

The Recovery ROM feature stores two complete firmware images in the ROM: one active image and one backup image. When the controller is powering up, it checks both firmware images to be sure they are valid. If either image is invalid, the system overwrites the invalid image with the valid image. This process, commonly called auto-flashing, is performed automatically by the controller and does not require any user intervention. The controller display provides messages for the status of this process.

Firmware Upgrades

The ROM flash tool enables system administrators to efficiently upgrade array controller ROM images. This tool has the following features:

• Supports Microsoft® Windows NT® 4.0, Windows® 2000, Novell NetWare (offline only), and Linux operating systems

Configuration and Utilities

• Integrates with other software maintenance, deployment, and operating system tools

• Automatically checks for hardware, firmware, and operating system dependencies, and installs only the correct ROM upgrades required by each target controller

For firmware procedures, refer to the SmartStart CD.

HP StorageWorks Modular Smart Array 500 System User Guide 4-3

Configuration and Utilities

Controller Firmware Auto Cloning

In a redundant controller configuration, both controllers must execute the same version of firmware. During power up (or when a redundant controller is installed as a hot-plug procedure), the system compares the controller firmware versions. If the versions differ, the controller displays a user input message seeking to initiate Controller Firmware Auto Cloning. If 60 seconds elapse with no user input, cloning begins automatically, and the system overwrites one firmware version with the other version.

When the cloning is complete, the system resets the modified controller. After the modified controller powers up, the controllers begin operating in redundant mode.

The system clones firmware based on the following criteria:

• Non-Hot-Plug Cloning—If the system powers up with both controllers installed, the system clones the most recent firmware version from either controller.

• Hot-Plug Cloning—If the system is operating and an optional redundant controller is installed, the system clones the firmware version from the primary controller, regardless of which firmware version is more recent. This cloning method ensures that all host-initiated I/O remains uninterrupted during system operation.

• Incompatible Version Cloning—If a specific version of firmware is incompatible with certain hardware revisions of a controller, the system displays the user input message seeking to initiate Controller Firmware Auto Cloning and clones the most recent firmware version that is compatible with both controllers.

IMPORTANT: During incompatible version cloning, the system does not reset the updated controller if the controller is operating and processing I/O. In this case, the system does not enter redundant mode and provides an informational message on the controller display. To configure redundancy, cycle the system power. Refer to “System Power Down” in Chapter 3.

Selective Storage Presentation

SSP is a controller firmware feature that enables the administrator to control access from multiple hosts to logical drives on the MSA500 system. The administrator selects which server host or hosts can access the stored data, restricting access as needed to assure data integrity and security.

Each logical drive on the controller has an access control list that contains the IDs of the server host adapters that have access to the drive. If a server attempts to send commands to a logical drive without access authority, the controller rejects the command.

The configuration utility maps the IDs of server host adapters to connection names and sets up access control lists for logical drives based on the adapter IDs.

SSP Hardware Configurations

To configure the hardware for SSP, use SCSI cables to connect each server to the 2-Port or 4-Port Shared Storage Module installed in the storage system. Boot volumes for individual servers can reside on server drives or storage system drives.

Configuration and Utilities

Firmware Requirements

For Selective Storage Presentation (SSP) support on the MSA500 system, be sure the following firmware versions are present:

• MSA500 Controller firmware Version 1.66 or later

• Smart Array 532, 5i, or 5i+ Controller firmware Version 2.36 or later

For the most recent firmware, refer to the software CD that ships with the MSA500 system or refer to

Enabling SSP

After choosing the configuration that best suits your needs, enable SSP with ACU Version 6.0 or later. Locate ACU on the SmartStart CD. For instructions, refer to the HP Array Configuration Utility User Guide on the Documentation CD.

Array Configuration Utility

ACU Version 6.0 (or later) is a browser-based utility with the following features:

• Supports online array capacity expansion, logical drive capacity extension, assignment of online spares, and RAID or stripe size migration

• Suggests the optimum configuration for an unconfigured system

• Provides different operating modes, enabling faster configuration or greater

control over the configuration options

• Remains available any time that the server is on

• Displays on-screen tips for individual steps of a configuration procedure

The minimum display settings for optimum performance are 800 × 600 resolution

and 256 colors. The server must have Microsoft Internet Explorer 5.5 (with Service Pack 1) installed and be running Microsoft Windows 2000, Windows NT 4.0, or Linux. Refer to the README.TXT file for further information about browser and Linux support.

For more information about ACU Version 6.0 (or later), refer to the HP Array Configuration Utility User Guide on the Documentation CD.

Moving Array Controller Drives and Arrays

CAUTION: Back up all data before removing drives or changing configurations.

Failure to do so could result in permanent loss of data. Before moving drives and arrays, run ACU.

4-6 HP StorageWorks Modular Smart Array 500 System User Guide

Configuration and Utilities

Drives can be moved to other ID positions on the same array controller. You can also move a complete array from one controller to another, even if the controllers are on different servers or storage devices. Arrays on different controllers can also be moved to another controller.

Before moving drives, observe the following requirements:

• No drives are failed, missing, or degraded.

• The move does not result in more than 14 physical drives.

• No more than 32 logical volumes are configured for a controller.

• The array must be in its original configuration with no active spare drives.

• Capacity expansion is not running.

• Controller firmware is the latest version (recommended).

• Controller is a Smart Array controller.

Before moving an array from one controller to another, observe these additional requirements:

• All drives in the array must be moved at the same time.

• Drive positions of the destination controller must match original drive positions.

When all requirements are met:

1. Power down the system. Refer to “System Power Down” in Chapter 3.

2. Move the drives. Refer to “Hot-Plug SCSI Hard Drive Options” in Chapter 3.

3. Power up the system. Refer to “System Power Up” in this chapter.

A #86 controller display message should appear, indicating that drive positions were changed and the configuration was updated. If a #121 controller display (no volumes) message is displayed, power down the system immediately to avoid data loss, and return the drives to their original locations.

For more information about display messages, refer to Appendix C, “Display Messages.”

4. Check the new drive configuration by running ACU. Refer to the HP Array Configuration Utility User Guide on the Documentation CD.

Configuration and Utilities

Expanding and Extending Capacity

CAUTION: Back up all data before removing drives or changing configurations.

Failure to do so could result in permanent loss of data. Before moving drives and arrays, run ACU.

Array Capacity Expansion is the addition of physical drives to an array that has already been configured. The capacity of these added physical drives may then be added to an existing logical drive on the array (capacity extension; refer to the next paragraph), or it may be configured into a new logical drive.

Logical Drive Capacity Extension is the enlargement of an existing logical drive after the corresponding array has undergone capacity expansion.

Use ACU to perform capacity expansion and extension. A data backup and restoration cycle is not required, even in non-fault-tolerant configurations.

With hot-plug drives, you can perform expansion online. Online extension is only possible with operating system support.

IMPORTANT: When extending a logical drive under Microsoft Windows 2000, upgrade the disk to DYNAMIC before creating a partition on that disk. If the disk already has a partition when it is upgraded to DYNAMIC, Windows 2000 may not allow logical drive extension. Refer

to the Windows 2000 documentation for details about DYNAMIC and BASIC disks.

IMPORTANT: Microsoft Windows NT 4.0 only allows four partitions on each logical drive.

Additional drive space created may not be accessible if the four partitions per logical drive limit are exceeded.

IMPORTANT: If you are running Microsoft Windows 2000 with Microsoft Cluster Services (MSCS), logical drive extensions are not recommended. MSCS requires that disks be configured as BASIC in logical disk manager. In order to take advantage of logical drive extension, the drives would have to be configured as DYNAMIC when the volume is initially created. Because of the differences in requirements for MSCS and the logical drive extension feature, we recommend you do not perform a logical drive extension on a storage enclosure that is part of a Microsoft Cluster.

— If you choose high priority, drive rebuilding occurs faster, at the expense of

normal I/O operations.

Accelerator Ratio

The MSA500 controller has an onboard cache called an Array Accelerator, which performs both write-posting and read-ahead caching. The setting in CPQONLIN determines the amount of memory allocated to the read and write caches. For example, if the Accelerator Ratio is set to Read 75%:Write 25%, 75% of Array Accelerator cache is dedicated to read-ahead cache and 25% is dedicated to the writeposting cache. This option can be modified from the controller Settings menu.

Expanding an Array

During an expand, performance may be slightly degraded. In most cases, however, any potential degradation is offset by the addition of physical drives. Some tips for expanding include:

• Perform the expand process during periods of low server use. If you must expand during peak periods, ACU for NetWare enables you to set the priority of the expand. Setting the priority to LOW affects performance the least, but it takes longer for the new space to become available.

• When expanding, always add drives with a capacity equal to or greater than the capacity of the smallest drive in the array. Adding larger drives wastes space because only the space that is equal to the smallest drive size can be used.

HP StorageWorks Modular Smart Array 500 System User Guide 4-13

Configuration and Utilities

Adding or Configuring Spare Drives

When adding a spare drive to an array, there must be an unassigned drive or a drive already assigned as a spare on another array. You can assign a single spare to any number of arrays or assign separate spares. When you select Assign Spare Drive, only drives that qualify will appear (for example, only those spares that are large enough will appear). If drives that you expect to see do not appear, switch to the physical drive view (Tab key), and check the size of the drives. The capacity of the spare must be equal to or greater than the capacity of the smallest drive in the array.

Online RAID and Stripe Migration

Using CPQONLIN, you can modify both the RAID level and stripe size of an existing logical drive while online. To migrate a drive:

1. Select the drive setting option under the logical drive menu for the drive you intend to modify.

2. Select the new RAID level and/or stripe size from the choices presented to you. If the new settings are valid, the migration will begin when you save the changes.

Failed Drives or Interim Recovery Mode

If a drive fails and hardware fault tolerance is enabled, operation continues. Replace the drive as soon as possible. Select a logical drive and press the F3 key to monitor the status of drive recovery.

4-14 HP StorageWorks Modular Smart Array 500 System User Guide

Configuration and Utilities

Drive status messages include:

• Interim Recovery: The logical drive is operating, but a failed drive has not been replaced. Replace drive as soon as possible.

• Ready for Recovery: The logical drives are queued for recovery. This status is displayed when another logical drive is already rebuilding or expanding.

• Rebuilding: The array is operating and rebuilding a replacement drive or an online spare, if one was assigned.

• Logical Drive Failed: If you have one or more logical drives that are not protected by fault tolerance in an array, the data on these logical drives will be lost. ACU shows the logical drives as FAILED. After drive replacement, any fault-tolerant logical drives rebuild. The logical drives that were not protected (FAILED) become available for data (the devices are reactivated automatically). If you have a backup of the data, restore the data now.

If you do not replace the failed drive, the only option using ACU is to delete logical drives. Do not delete logical drives that contain valid data. Doing so results in data loss.

HP StorageWorks Modular Smart Array 500 System User Guide 4-15

Configuration and Utilities

NOTE: A failed status can occur on drives protected by fault tolerance if two or more physical drives fail concurrently.

Some status messages are available without pressing the F3 key. For example, on the Main menu, the FAILED status appears next to the logical drive that has failed.

EXPANDING and REBUILDING appear next to the array in which the activity is occurring.

Handling Disk Drive Failures

If the MSA500 controller was configured with hardware fault tolerance, complete the following steps after a disk drive failure.

1. Determine which physical drive failed. On hot-plug drives in a ProLiant server or storage system, failure is indicated by an amber drive failure LED on each drive tray.

2. If the unit containing the failed drive does not support hot-plug drives, perform a normal system shutdown.

3. Remove the failed drive and replace it with a drive that is of the same capacity. For hot-plug drives, after you secure the drive in the bay, the LEDs on the drive each flash once in an alternating pattern to indicate that the connection was successful. The online LED flashes, indicating that the controller recognized the drive replacement and began the recovery process.

4. Power up the server, if applicable.

5. The MSA500 controller firmware reconstructs the information on the new drive,

based on information from the remaining physical drives in the logical drive. While reconstructing the data on hot-plug drives, the online LED flashes. When the drive rebuild is complete, the online LED is illuminated.

6. NetWare cannot detect a single physical drive failure when using hardware-based fault tolerance; NetWare determines that the data is still valid and accessible during the rebuilding process. However, the driver knows that a physical drive has failed. A message is printed on the console notifying the user that a physical drive is in a degraded state. CPQONLIN will also show the drive has failed.

Optimizing Array Controller Performance

To improve system performance, keep these tips in mind before creating NetWare volumes or partitions:

• If you selected a fault-tolerance option, such as mirroring or distributed data guarding, when using the System Configuration Utility, do not select mirroring while using INSTALL.NLM. The fault-tolerance capabilities of the MSA500 controller provide performance improvements and automatic data recovery features.

• Novell recommends creating volumes with a 64-KB block size and using the Block Sub-Allocation feature of NetWare. Using a large block size decreases the amount of RAM required to mount the volume, while Block Sub-Allocation allows NetWare to allocate disk space more efficiently.
