vi 3ware Serial ATA RAID Controller User Guide for the Power Mac G5
About this User Guide This document, 3ware Serial ATA RAID Controller User Guide for the Power Mac G5, provides instructions for configuring and maintaining RAID units on your 3ware 9590SE-4ME RAID controller. This guide assumes that you have already installed your controller in your system and connected it to your 3ware® Sidecar external enclosure. If you have not yet done so, see the installation guide that came with your controller.
Table 1: Chapters and Appendices in this User Guide Chapter/Appendix Description 5. Configuring Units Describes how to configure new units and spares, change existing configurations, and set unit policies. 6. Maintaining Units Describes how to check unit and drive status, review alarms and errors, schedule background maintenance tasks, and manually start them, when necessary or desirable. Includes explanations of initialization, verify, rebuild, and self-tests. 7.
1 Getting Started with Your 3ware RAID Controller Setting up your 3ware RAID controller involves these main steps: • Physically Install the Controller and Drives • Install the 3ware Driver and Disk Management Software • Configure the RAID Unit and Drives • Set Up Management and Maintenance Features Tip: When you are first setting up your system, you may want to review “System Requirements” on page 5.
Chapter 1. Getting Started with Your 3ware RAID Controller these features allow you to begin using your newly configured units right away. You can review and change these features as a final step in your initial setup, or you can make changes to them later, at your convenience.
Initial Settings for Policies and Background Tasks The table below lists the default settings for policies. These settings are used if you do not explicitly change the policy settings.
2 Introducing the 3ware® 9590SE-4ME RAID Controller The 3ware 9590SE-4ME RAID controller is a 4-lane (x4) PCI Express® card. It can be installed in any of the available x4 or x8 PCI Express slots on your Power Mac® G5 (PowerPC™-based). (The x16 slot is normally reserved for your graphics card.) It features: • Support for up to 4 SATA drives. • AMCC’s remote management software, 3ware Disk Manager 2 (3DM®2) which simplifies storage configuration and management through a web browser.
System Requirements System Requirements 3ware 9590SE-4ME RAID controllers require the following: • Drives Drives must be 3.5" and meet serial ATA 150 (SATA-1) or serial ATA 300 (SATA 2) Gb/s standards. SATA 2 drives will have better performance. A list of drives that have been tested is available at http://www.3ware.com/products/cables.asp • Operating System and Computer Mac OS 10.4 or later, running in a Power Mac G5 (PowerPC-based) with PCI Express.
Chapter 2. Introducing the 3ware® 9590SE-4ME RAID Controller Understanding RAID Concepts and Levels 3ware RAID controllers use a Redundant Array of Inexpensive Disks (RAID) to increase your storage system’s performance and provide fault tolerance (protection against data loss).
Understanding RAID Concepts and Levels Available RAID Configurations The following RAID levels and configurations are available for drives attached to a 9590SE-4ME 3ware RAID controller: • • • • • • RAID 0 RAID 1 RAID 5 RAID 10 Single Disk Hot Spare For how to configure RAID units, see “Configuring a New Unit” on page 34. RAID 0 RAID 0 provides improved performance, but no fault tolerance.
Chapter 2. Introducing the 3ware® 9590SE-4ME RAID Controller preserving the data on one drive if the other drive fails. Fault tolerance is a basic requirement for critical systems like web and database servers. 3ware uses a patented technology, TwinStor®, on RAID 1 arrays for improved performance during sequential read operations. With TwinStor technology, read performance is twice the speed of a single drive during sequential read operation.
Understanding RAID Concepts and Levels RAID 10 RAID 10 is a combination of striped and mirrored arrays for fault tolerance and high performance. When drives are configured as a striped mirrored array, the disks are configured using both RAID 0 and RAID 1 techniques, thus the name RAID 10 (see Figure 4). A minimum of four drives are required to use this technique. The first two drives are mirrored as a fault tolerant array using RAID 1.
Chapter 2. Introducing the 3ware® 9590SE-4ME RAID Controller Determining What RAID Level to Use Your choice of which type of RAID unit (array) to create will depend on your needs. You may wish to maximize speed of access, total amount of storage, or redundant protection of data. Each type of RAID unit offers a different blend of these characteristics. The following table provides a brief summary of RAID type characteristics.
3ware Tools for Configuration and Management Through drive coercion, the capacity used for each drive is rounded down so that drives from differing manufacturers are more likely to be able to be used as spares for each other. The capacity used for each drive is rounded down to the nearest GB for drives under 45 GB (45,000,000,000 bytes), and rounded down to the nearest 5 GB for drives over 45 GB. For example, a 44.3 GB drive will be rounded down to 44 GB, and a 123 GB drive will be rounded down to 120 GB.
Chapter 2. Introducing the 3ware® 9590SE-4ME RAID Controller Monitoring, Maintenance, and Troubleshooting Features Several 3ware RAID controller features aid in monitoring and troubleshooting your drives. • SMART Monitoring (Self-Monitoring, Analysis and Reporting Technology) automatically checks a disk drive's health every 24 hours and reports potential problems. This allows you to take proactive steps to prevent impending disk crashes.
Monitoring, Maintenance, and Troubleshooting Features • Drive Locate. You can issue drive locate commands that blink the LEDs for particular drives, so that you can quickly identify what drive needs to be checked or replaced. (For more information, see “Locating a Drive by Blinking Its LED” on page 81.) • Auto Rebuild. For times when you do not have a spare available, setting the Auto Rebuild policy allows rebuilds to occur with an available drive or with a failed drive.
3 3DM 2 (3ware Disk Manager) Introduction Note: 3DM 2 includes software developed by the OpenSSL Project for use in the OpenSSL Toolkit (http://www.openssl.org/). 3ware Disk Manager 2 (3DM 2) allows you to manage and view the status of your 3ware RAID controller and associated drives. There are two parts to 3DM: a process, that runs in the background on the computer where you have installed your 3ware controller, and a web application that can be used to access it.
Browser Requirements for 3DM Browser Requirements for 3DM 3DM runs in most current web browsers. Tested and supported browsers include: • Safari 2.0.4 or newer • Firefox 1.5.0.4 or newer Additional requirements: • JavaScript must be enabled • Cookies must be enabled • For best viewing, use a screen resolution of 1024 X 768 or greater, and set colors to 16 bit color or greater.
Chapter 3. 3DM 2 (3ware Disk Manager) Introduction Uninstalling 3DM on the Macintosh You can remove 3DM from your Macintosh by using the uninstall command located in the AMCC folder.

Passwords are case sensitive. You can only change passwords if you are logged in as Administrator.
Chapter 3. 3DM 2 (3ware Disk Manager) Introduction • Information will send e-mails for all events • Warning will send e-mail for events with severity of Warning and Error. • Error will send e-mail for events with severity of Error only. For more information about events and alarms, see “Viewing Alarms, Errors, and Other Events” on page 66. (Note: Events are listed on the 3DM page called “Alarms.”) Event notification can be set up during 3DM installation, and can be changed on the 3DM 2 Settings page.
Setting Up 3DM Preferences To enable or disable remote access 1 Click 3DM 2 Settings on the menu bar. 2 In the Remote Access section of the 3DM 2 Settings page, select either Enabled or Disabled in the Allow Remote Connections field. The page refreshes, and a message at the top of the screen confirms that remote access has been enabled or disabled. Setting the Incoming Port # You can set the port which 3DM uses to listen for incoming messages.
4 Configuring Your Controller This section describes how to view details about the controller, check its status, and change configuration settings that affect the controller and all of the drives connected to it.
Viewing Information About a Controller Figure 9. Controller Summary Page Tip: If you are managing controllers remotely, the list of controllers is for the machine with the IP or URL you entered in the browser address bar. 2 To see more details about a particular controller, click the ID link for that controller to display the Controller Details page. Figure 10.
Chapter 4. Configuring Your Controller Note: Throughout this documentation, the term current controller is used to refer to the controller currently selected in this drop-down list. Viewing Controller Policies You can view the current state of controller policies in 3DM, in the Other Controller Settings section at the bottom of the Controller Settings page (See Figure 11.) Only the Auto Rebuild, Auto-Carving, and Carve Size policies can be changed on this page.
About Controller Policies About Controller Policies The following policies affect all units and drives on a controller and can be adjusted as appropriate for your equipment. Controller policies are shown at the bottom of the Controller Settings page. • Auto Rebuild. Determines whether the Auto Rebuild policy is enabled or disabled. When disabled, degraded units can only be rebuilt with designated spares.
Chapter 4. Configuring Your Controller To enable Auto Rebuild through 3DM 1 Choose Management > Controller Settings from the menu bar in 3DM. 2 In the Other Controller Settings section at the bottom of the screen, select the Enabled option for Auto Rebuild. The page refreshes, and a message at the top confirms the change you have made.
Setting the Size of Volumes Created with Auto-Carving 2 Create a new unit or migrate an existing unit to include the drives you want to use. If the combined capacity of the drives exceeds the carve size, a number of volumes will be created. 3 Verify the creation of the volumes. In 3DM 2, the number of volumes is shown on the Unit Details page. 4 Verify that the volumes appear in the operating system. They will appear as additional drives.
5 Configuring Units This section includes information and procedures on configuring units attached to your 3ware RAID controller.
Configuring a New Unit Configuration Options When Creating a Unit This section provides an overview of the choices you have when configuring a new unit. For step-by-step instructions, see “Creating a Unit” on page 37.
Chapter 5. Configuring Units Name of the unit (optional) Units can be given names. These names will be visible in 3DM. Stripe size, if appropriate for the RAID level In general, smaller stripe sizes are better for sequential I/O, such as video, and larger stripe sizes are better for random I/O (such as databases). Striping size is not applicable for RAID 1, because it is a mirrored array without striping. Using the default stripe size of 64KB usually gives you the best performance for mixed I/Os.
Configuring a New Unit Creating a Unit In 3DM, creating a unit starts from the Management > Maintenance page (Figure 12). Figure 12. 3DM Maintenance Page To create a unit 1 In 3DM, choose Management > Maintenance. 2 In the Available Drives list, select the drives you want to include in the unit by marking the checkbox in front of the Port number for each one. If you are creating single drive units (single disks or hot spares), you can configure multiple drives at once. 3 Click Create Unit.
Chapter 5. Configuring Units 4 In the Type field, select the RAID configuration you want. 5 If stripe size applies to the RAID type you select, select a Stripe Size. (Stripe size does not apply to RAID 1.) 6 Optional: In the Name box, enter a name for the unit (up to 21 characters, including dashes and underscores). 7 Make changes to the unit policies, as desired. You can enable or disable the Write Cache, Auto Verify, and Continue on Source Error During Rebuild.
Configuring a New Unit To initialize and partition your unit 1 In the Mac OS message, click Initialize. Figure 14. Disk Insertion Message from the Mac OS 2 When the Macintosh Disk Utility window opens, find and select the drive that represents your RAID unit. Figure 15. Macintosh Disk Utility Window with New RAID Unit www.3ware.
Chapter 5. Configuring Units 3 In the Disk Utility Window, select the Partition tab. Figure 16. Macintosh Disk Utility Window, Partition Tab 4 In the Volume Scheme column, click Current to show the drop-down menu and select the number of partitions that you want your RAID unit to have. Tip: If you only want one volume, select 1 Partition. (Each partition will appear as a separate drive on your computer.) Figure 17.
Configuring a New Unit 5 On the right, specify a volume name and then click Partition. Figure 18. Defining the Volume in the Macintosh Disk Utility a) Enter a name b) Click Partition 6 When a message asks you to confirm you want to partition the disk, click Partition. Figure 19. Confirmation Message to Create the Partition You will see a series of messages appear toward the bottom of the Disk Utility window as the RAID unit is first partitioned and then formatted.
Chapter 5. Configuring Units Figure 20. Macintosh Disk Utility Showing Partitioning Progress Messages appear here as the unit is formatted. When the partitioning is complete, icons for each new volume appear on your desktop. They are now ready for use. You can now close the Macintosh Disk Utility window. Your RAID unit is ready for use. Creating a Hot Spare You can designate an available drive as a hot spare.
Naming a Unit Note: 3ware’s 9000 series RAID controllers use drive coercion so that drives from differing manufacturers and with slightly different capacities are more likely to be able to be used as spares for each other. Drive coercion slightly decreases the usable capacity of a drive that is used in redundant units. The capacity used for each drive is rounded down to the nearest GB for drives under 45 GB (45,000,000,000 bytes), and rounded down to the nearest 5 GBytes for drives over 45 GB.
Chapter 5. Configuring Units 4 In the text box, enter or type over the name shown. A name can be up to 21 characters, and can include dashes and underscores. 5 Click the Save Names button. Note: If you want to cancel your change before saving it, click the Reset Names button. Setting Unit Policies The following polices are set when you create a unit, and can be adjusted later through settings on the Management > Controller Settings pages of 3DM.
Setting Unit Policies • StorSave Profile. Determines what StorSave profile is used for the unit. Three profiles are available: Protection, Balanced, and Performance. For details, see “Setting the StorSave Profile for a Unit” on page 48. Figure 21. Unit Policies on Controller Settings Page in 3DM Enabling and Disabling the Unit Write Cache Write cache is used to store data locally in memory on the drive before it is written to the disk drive media, allowing the computer to continue with its next task.
Chapter 5. Configuring Units To enable or disable unit write cache through 3DM 1 Choose Management > Controller Settings from the menu bar in 3DM. 2 In the Unit Policies section of the Controller Settings page, check the Write Cache box to enable it for the designated unit. The page refreshes, and a message at the top confirms the change you have made. A message will caution you about enabling write cache without a BBU.
Setting Unit Policies Setting Continue on Source Error During Rebuild The Continue on Source Error During Rebuild policy is available for units which are redundant. (For units which are not redundant, this option is not shown on the screen.) When this policy is set, ECC (Error Correcting Code) errors are ignored when they are encountered during a rebuild. (ECC errors are typically defects that have been detected in the drive since initialization.
Chapter 5. Configuring Units Note: Not all drives support NCQ. If a drive does not support NCQ, the policy setting for the controller is ignored. To enable or disable queuing for a unit through 3DM 1 Choose Management > Controller Settings from the menu bar in 3DM. 2 In the Unit Policies section of the Controller Settings page, enable queuing by checking the box under “Queuing” for the designated unit; disable it by unchecking the box.
Setting Unit Policies • FUA (Force Unit Access). FUA commands are a way that the RAID controller or a program (such as a database program) can ensure that data is actually written to the disk drive media, and is not stored in cache. When a write command is followed with a FUA command, then the disk drive will only issue “command complete” to the controller once the data is written to media. When performance is considered more important than protection, it may be desirable to ignore FUA commands.
Chapter 5. Configuring Units Changing An Existing Configuration You can convert one RAID configuration into another while the unit is online. This process is known as RAID Level Migration (RLM). You can use RAID Level Migration to make two main types of configuration changes: • RAID Level (for example, a RAID 1 to a RAID 5) • Unit Capacity Expansion (for example, adding a 4th drive to a 3-drive RAID 5) You can also use RLM to change the stripe size of a unit.
Changing An Existing Configuration Figure 22. RAID Level Migration Example Typically, a unit is reconfigured with the same or more storage capacity. Sometimes additional drives are added. The following table shows valid reconfigurations, some of which will require the addition of more drives.
Chapter 5. Configuring Units Changing RAID Level You can use migrate to change the RAID level of an existing unit while the unit is online, without experiencing any data loss. When you change a RAID level, you may also add one or more drives to the unit. You can also migrate to change the unit's stripe size. For example, a four-drive RAID 5 with a 64KB stripe size can be migrated to a four-drive RAID 5 with 256KB stripe size. The steps below describe how to change a RAID level in 3DM2.
Changing An Existing Configuration Expanding Unit Capacity You can expand a unit's capacity by adding one or more drives to it without changing the RAID level, except for singles and RAID 1 units. (Since a single can only have one drive, and a RAID 1 can only have two drives, if you add a drive to either, the RAID level must be changed.) For a RAID 5 with 3 drives, you can change the capacity by adding a forth drive.
Chapter 5. Configuring Units Note: This step can only be done after the system has completed the migration or online capacity process. The operating system will not see the capacity until that process is complete. To inform the operating system that a unit has been changed 1 Unmount the file system from the unit. Launch the Macintosh Disk Utility, select the unit, and click the Unmount button the toolbar, or select the icon for the unit on the desktop and drag it to the trash.
Deleting a Unit 2 Backup any data you want to keep. 3 Unmount the unit. Launch the Macintosh Disk Utility, select the unit, and click the Unmount button the toolbar, or select the icon for the unit on the desktop and drag it to the trash. This step is very important. If a unit is not unmounted and you delete it, it is the equivalent of physically yanking a hard drive out from under the operating system. You could lose data, the system could hang, or the controller could reset.
Chapter 5. Configuring Units Figure 24. Unit Successfully Deleted through 3DM Removing a Unit Removing a unit allows you to safely remove drives from a controller in order to move the unit to another controller or to store the drives for safekeeping purposes. This process is sometimes referred to as “array roaming.” When you remove a unit (in contrast to deleting a unit), information about the unit remains intact on the drives.
Moving a Unit from One Controller to Another Launch the Macintosh Disk Utility, select the unit, and click the Unmount button the toolbar, or select the icon for the unit on the desktop and drag it to the trash. This step is very important. If a unit is not unmounted and you remove it, it is the equivalent of physically yanking a hard drive out from under the operating system. You could lose data, the system could hang, or the controller could reset. 3 In 3DM, choose Management > Maintenance.
Chapter 5. Configuring Units Adding a Drive You can add a drive to your 3ware Sidecar and make it available through 3DM without powering down the system. To add a drive 1 Insert the drive in your 3ware Sidecar. (For details, see 3ware Sidecar Kit with the 9590SE-ME: Installation Guide.) 2 In 3DM, choose Management > Maintenance. 3 On the Maintenance page, click Rescan Controller. The drive will appear in the list of available drives.
Removing a Drive 3 When 3DM asks you to confirm that you want to remove the drive, click OK. Figure 25. Removing a Drive in 3DM You can now remove the drive from your system. If you removed a drive that was part of a unit, the unit may become degraded, as shown in (Figure 26). Figure 26. Result of Removing Drive from Unit in 3DM www.3ware.
Chapter 5. Configuring Units Rescanning the Controller When you make a change by physically adding or removing drives or units, you can have 3DM rescan the controller to update the list of units and available drives shown on the Maintenance page. This is useful in a variety of circumstances. For example, if you add new drives to the controller, you can make them available by rescanning the controller.
6 Maintaining Units 3ware RAID controllers include a number of features in the firmware that help maintain the integrity of your drives, check for errors, repair bad sectors, and rebuild units when drives degrade. In addition, 3ware Disk Manager (3DM) provide tools to let you check unit and drive status, and manually start background maintenance tasks. 3DM also lets you review alarms and errors and schedule background maintenance tasks.
Chapter 6. Maintaining Units Figure 27.
Checking Unit and Drive Status Enclosure LED Status Indicators The LEDs on your enclosure also provide status information about your drives and units. Table 8: Meaning of LED Colors and Behavior Color Drive Status Solid green OK Blinking green Identify This occurs when you have used the Identify command in 3DM to locate a particular drive or unit. (See “Locating a Drive by Blinking Its LED” on page 81.
Chapter 6. Maintaining Units • Initializing. The unit is in the process of writing to all of the disks in the unit in order to make the array fault tolerant. For more information, see “About Initialization” on page 69. • Initializing-Paused. The unit is set to initialize, however scheduling is enabled and the present time is not during a scheduled timeslot. Initializing will start at the next scheduled time slot.
About Degraded Units About Degraded Units Fault tolerant RAID units provide data redundancy by duplicating information on multiple drives. These RAID units make it possible to continue use even if one of the drives in the unit has failed. • RAID 1 and 10 units each use mirroring to achieve fault tolerance. Identical data is stored on two or more drives to protect against drive failure.
Chapter 6. Maintaining Units Alarms, Errors, and Other Events 3DM provides several levels of detail about alarms, errors, and other events: • A summary log of all events and notifications on the Alarms page • A detailed error listing, available for download from the Controller Details page • SMART data for individual drives Viewing Alarms, Errors, and Other Events The Alarms page in 3DM shows a log of all events (also called Asynchronous Event Notifications, or AENs) that have occurred on units.
Alarms, Errors, and Other Events Downloading an Error Log You can download an error log containing information from the firmware log. This can be useful when troubleshooting certain types of problems. For example, you might want to send the saved file to 3ware Customer Support for assistance when troubleshooting. To download the error log 1 In 3DM, choose Information > Controller Details from the menu bar. 2 Make sure the correct controller is displayed in the Select Controller field in the menu bar.
Chapter 6. Maintaining Units Background Tasks Background tasks are maintenance tasks that help maintain the integrity of your drives and data. These tasks include • Initialization of units • Verification of units • Rebuilds when units have become degraded • Migration of an on-line RAID from one RAID configuration to another • Self-tests You can set up your system so that these tasks occur as they are needed, or you can create schedules so that they occur during non-peak times.
Background Tasks About Initialization For 3ware SATA RAID controllers, initialize means to put the redundant data on the drives of redundant units into a known state so that data can be recovered in the event of a disk drive failure. For RAID 1 and 10, initialization copies the data from the lower port to the higher port. For RAID 5, initialization calculates the RAID 5 parity and writes it to disk. This is sometimes referred to as background initialization or resynching, and does not erase user data.
Chapter 6. Maintaining Units Initialization of RAID 1 and RAID 10 Units RAID 1 and RAID 10 units do not need to be initialized when they are created to be fault tolerant and are immediately available for use with full performance when created. Initialization of RAID 1, RAID 10 units will take place automatically the first time the unit is verified. Initialization of a RAID 1 unit results in data from one disk (the disk on the lower port number) being copied to the other disk.
Background Tasks What Verification Does For a RAID 1 or RAID 10 unit, a verify compares the data of one mirror with the other. For RAID 5, a verify calculates RAID 5 parity and compares it to what is written on the disk drive. Verification checks each sector on a drive. This is important, because day-today use of the media may leave many sectors on a drive unused or unchecked for long periods of time. This can result in errors occurring during user operation.
Chapter 6. Maintaining Units How Errors Are Handled Verification makes use of the same error checking and error repair techniques used during ordinary use of drives configured through 3ware RAID controllers. When verification encounters an error, the controller typically retries the command. If there are cable CRC errors, there may be multiple retries including downgrade of the UDMA mode. If the error persists and is unrepairable (e.g., ECC errors), an error notification is issued to indicate the problem.
Background Tasks To verify a unit through 3DM 1 In 3DM, choose Management > Maintenance. 2 In the Unit Maintenance section of the Maintenance page, select the unit you want to verify and click Verify Unit. 3DM puts the selected unit in verifying mode. If verify scheduling is not enabled on the Scheduling page, the verification process begins almost immediately. If verify scheduling is enabled, the unit will not start actively verifying until the next scheduled time.
Chapter 6. Maintaining Units Note: If a rebuild fails, check the Alarms page for the reason. If there was an ECC error on the source disk, you can force the rebuild to continue by checking the Overwrite ECC Error policy on the Controller Settings page in 3DM and then running Rebuild again. This will cause uncorrectable blocks to be rewritten, but the data may be incorrect. It is recommended that you execute a file system check when the rebuild completes.
Background Tasks Cancelling a Rebuild and Restarting It with a Different Drive You can cancel a rebuild by using the Remove Drive link on the Maintenance page. Note: If you want to pause the rebuild process through 3DM, you can do so by setting or changing the rebuild schedule on the Scheduling page. If you set a schedule for rebuilds that does not include the current time, the rebuild process will pause.
Chapter 6. Maintaining Units Background Task Prioritization Although migration tasks follow the same schedule as rebuild and initialization tasks, they are always given the highest priority because of the controller and disk resources required during migration. Once a unit is put into the migration state, it must be allowed to complete the process. While migrating, rebuilds or verifies to the unit are not permitted. Rebuilding preempts verify operations.
Scheduling Background Tasks Tip: If you want to change a scheduled task, you first remove the scheduled item and then add it back with the desired day, time, and duration. Note: Setting up the Scheduling window does not actually request background tasks. It simply specifies when they can run. For more information about the background tasks themselves, see “Background Tasks” on page 68. You can also set the rate at which background tasks are performed compared to I/O tasks.
Chapter 6. Maintaining Units Figure 29. Selecting Task Schedules to View Turning On or Off Use of a Task Schedule Turning on the schedule for Rebuild/Migrate and Verify tasks forces rebuilds, migrates, and verifies to be performed only during the time specified by the schedule. If the schedule is not turned on, rebuilds, migration, initialization, and verify can happen whenever they are required or are manually started.
Scheduling Background Tasks 3 In the Schedule Rebuild Tasks section, select the appropriate setting: Follow Schedule or Ignore Schedule. The illustration below shows this setting for the rebuild task schedule. Note: Self-test schedules cannot be turned off in this way. To disable self-tests you must either remove all schedule times, or uncheck the tests listed in the Tasks column. For more information, see “Selecting Self-tests to be Performed” on page 80.
Chapter 6. Maintaining Units To add a task schedule slot 1 Choose Management > Schedule from the menu bar. The Scheduling page appears, showing the schedule for Rebuild/Migrate Tasks. 2 To view Verify Tasks or Self-test Tasks, select it from the drop-down list at the top of the page. 3 Scroll to the section of the Scheduling page that shows the task you want to add. 4 In the fields at the bottom of the section, select the Day, Time, and Duration for the task. 5 Click the Add New Slot button.
Locating a Drive by Blinking Its LED 3 Check the boxes next to the self-tests you want to be performed. To disable self-tests Unlike scheduling of rebuilds and verifies, scheduling of self-tests is always enabled. To disable self-tests you must either remove all schedule times, or uncheck the tests listed in the Tasks column. Locating a Drive by Blinking Its LED You can easily identify the drives in a unit, or an individual drive, by causing the LEDs associated with the drives to blink.
Chapter 6. Maintaining Units To blink the LEDs for all drives in a unit 1 Choose from the main menu in 3DM. 2 On the list of units, locate the unit you want to identify. 3 Check the box in the Identify column. The LEDs associated with each drive in the unit begin blinking on the enclosure.

By default, queuing is disabled.
Chapter 8. 3DM 2 Reference • Smallest usable spare. • Smallest usable unconfigured (available) drive. • Smallest usable failed drive. For additional information, see “Setting the Auto Rebuild Policy” on page 31. Auto-Carving. Auto-carving can be enabled or disabled by selecting the appropriate radio button. When this feature is enabled, any unit that is over a specified size (known as the carve size) will be broken down into multiple volumes of that size, plus a remainder volume.
Scheduling page Scheduling page Figure 38. Scheduling Page The Scheduling page appears when you choose Management > Scheduling from the menu bar. The Scheduling page lets you set up a schedule for when background tasks (rebuild, migrate, initialize, verify, and self-test) should occur. Background tasks can have impact on the performance of your system, so you may prefer to schedule them at times when they will be least disruptive, such as in the middle of the night or on a weekend.
Chapter 8. 3DM 2 Reference Follow Schedule/Ignore Schedule. You can enable or disable the schedule for the Rebuild/Migrate and Verify tasks by selecting either Follow Schedule or Ignore Schedule. When schedules are set to be ignored, these tasks can be performed at any time, and are not restricted to the scheduled times. For details about the different background tasks, see “Background Tasks” on page 68. Task Schedules Initially, 7 schedule slots are defined, for 24 hours each.
Maintenance page Check SMART Thresholds. This test checks to see whether SMART thresholds have been exceeded. The SMART thresholds indicate when a drive is likely to fail, based on the number of errors that have been recorded through SMART (Self-Monitoring, Analysis and Reporting Technology). If any of the disk drives have detected a “threshold exceeded” condition, then an AEN is logged to the 3DM Alarms page. Moreover, if anything unusual is found during any self-test, it will be logged as an Alarm.
Chapter 8. 3DM 2 Reference Rescan Controller The Rescan Controller button scans the ports on the controller. Rescanning updates the list of available drives shown and updates the status of all ports. If error conditions have been fixed, the status is updated to reflect that. Rescanning is useful in variety of maintenance tasks. For example, if you physically plug in a drive and want the controller to recognize the newly plugged in drive, Rescan will find it.

Chapter 9.
Error and Notification Messages Error and Notification Message Details 0001 Controller reset occurred The 3ware RAID controller has detected a soft reset from the device driver. If the 3ware RAID controller fails to respond to the device driver within a reasonable amount of time, the device driver may issue a soft reset to the 3ware RAID controller and retry the command packet. For more information, see http://www.3ware.com/KB/article.aspx?id=14923.
Chapter 9. Troubleshooting 0006 Incomplete unit detected At power-on initialization time, or during a rescan, the 3ware RAID controller performs a “rollcall” of all drives attached to the card. After detection of the drives, the 3ware RAID controller then uses an internal algorithm to logically connect drives that belong to the same unit. If after rollcall a member of a unit is not found, the INCOMPLETE UNIT message is sent.
Error and Notification Messages controller detects this condition, it notifies you, prior to entering the recovery phase, by displaying this message. Possible causes of drive timeouts (also known as APORT time-outs) include a bad or intermittent disk drive, power cable or interface cable. For links to drive manufacturer diagnostic utilities and troubleshooting advice, see http://www.3ware.com/KB/article.aspx?id=14924.
Chapter 9. Troubleshooting 000E Initialize failed The 3ware RAID controller was unable to complete the initialization. This error can be caused by unrecoverable drive errors. If this unit was a redundant unit, and the 'initialize failed' happened because of a problem on a particular disk drive, then the unit will be degraded on that disk drive's port.
Error and Notification Messages 001E Unit inoperable Drive removal caused a unit to become inoperable. This message is sent after offline unit timer expires (20 seconds); if the unit becomes operational before the timer expires (20 seconds) there will be no message since there were no IO errors. 001F Unit Operational Drive insertion caused a unit that was inoperable to become operational again. Any data that was on that unit will still be there.
Chapter 9. Troubleshooting The fact that a sector repair message has been sent to you is an indication of the presence of grown defects on a particular drive. While typical modern disk drives are designed to allow several hundred grown defects, special attention should be paid to any drive in a unit that begins to indicate sector repair messages. This may be an indication of a drive that is beginning to fail.
Error and Notification Messages 0027 DCB checksum error detected The 3ware RAID controller stores certain configuration parameters on a reserved area of each disk drive called the Drive Configuration Block (DCB). As part of power-on initialization, the 3ware RAID controller performs a checksum of the DCB area to ensure consistency. If this error occurs, please contact 3ware technical support. The drive’s DCB has been corrupted.
Chapter 9. Troubleshooting by improper shutdown of the unit. This possibility applies to RAID 1, 10, and 5. A rebuild will re-synchronize the unit When this message is generated, redundant units will be automatically initialized. The initialize will not erase user data, but will recalculate and rewrite user parity data. For more information on the Initialize function, see “About Initialization” on page 69.
Error and Notification Messages jumpered in the wrong place. The converter must be correctly jumpered to correspond to UDMA 100 or 133 drives. For a list of compatible drives, see http://www.3ware.com/products/compatibility_sata.asp. 0032 Spare capacity too small for some units This message is sent by the controller when it finds a valid hot spare but the capacity is not sufficient to use it for a drive replacement for existing units.
Chapter 9. Troubleshooting 0038 SO-DIMM not detected This message applies to the 3ware 9500S controller which has removable memory. This message will be sent if there is no SODIMM memory connected to the controller. In this case, the controller is inoperable and cannot be used until a compatible SO-DIMM is put on the controller. For a list of SODIMMs compatible with the 9500S, see http://www.3ware.com/KB/article.aspx?id=11748. Other 3ware controller models do not have memory that can be removed.
Error and Notification Messages 003D Verify paused This message will be sent when the verify operation is paused. Verifies are normally paused for ten minutes after a system first boots up and during non-scheduled times when scheduling is enabled. 003E Migration paused This message is sent when migration is paused. Migration follows the rebuild schedule. For more information, see “Scheduling Background Tasks” on page 76.
Chapter 9. Troubleshooting 0043 Backup DCB read error detected This message will be sent when the controller sees a latent error in the backup Disk Configuration Block (DCB). A scrubbing activity will be started to repair any sector errors on getting this error. An effort is made to read the backup DCB even when the primary DCB is successfully read.
Error and Notification Messages the 3ware RAID controller. This indicates that the Battery Backup Unit must be replaced. 0049 Battery temperature is normal The Battery Backup Unit measures and evaluates the battery pack temperature on a continuous basis. If the temperature falls outside the acceptable range then comes back within the acceptable range, this message will be posted to the host.
Chapter 9. Troubleshooting 004E Battery capacity test started This message is posted when the Battery Backup Unit starts a battery test. The test estimates the battery capacity in hours, which is how long the Battery Backup Unit can back up the 3ware RAID controller. This test performs a full battery charge/discharge/re-charge cycle and may take up to 20 hours to complete.
Error and Notification Messages 0055 Battery charging started This message is posted when the Battery Backup Unit starts a battery charge cycle. 0056 Battery charging completed This message is posted when the Battery Backup Unit completes a battery charge cycle. 0057 Battery charging fault This message is posted when the charger of the Battery Backup Unit has detected a battery fault during a charge cycle. The Battery Backup Unit becomes not ready and is unable to backup the 3ware RAID controller.
Chapter 9. Troubleshooting 005D Battery health check failed The Battery Backup Unit periodically evaluates the health of the battery and its ability to backup the 3ware RAID controller in case of a power failure. This message is posted when the result of the health test is below the fault threshold. This indicates that the battery pack must be replaced. The Battery Backup Unit becomes not ready and is unable to backup the 3ware RAID controller.
