About this User Guide
This document, 3ware Serial ATA RAID Controller User Guide for Mac OS X,
provides instructions for configuring and maintaining RAID units on 3ware
9650SE and 9590SE controllers used with Mac OS X systems.
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.
If you do not have the printed copy, a PDF of the installation guide is
available on your 3ware CD, or you can download it from: http://
www.3ware.com/support/userdocs.asp. (Note that there are different
installation guides for different 3ware RAID controller models. The 9650SE4LPME is part of the 3ware Sidecar Kit.)
There are often multiple ways to accomplish the same configuration and
maintenance tasks for your 3ware RAID controller. This manual includes
instructions for performing tasks using 3ware Disk Manager 2, referred to as
3DM 2.
You can also perform many tasks at the command line, using 3ware’s
Command Line Interface (CLI). The CLI is described in a separate manual:
3ware Serial ATA RAID Controller CLI Guide. Information from both this
Users Guide and the CLI Guide are also available in the 3ware HTML
Bookshelf, available in the 3ware Documentation folder and on your 3ware
CD. (For more information, see “Using the 3ware HTML Bookshelf” on
page viii.)

Chapter 1. Getting Started with Your 3ware RAID Controller
Set Up Management and Maintenance Features
3ware RAID controllers include a number of features to help you manage and
maintain the controller and your configured units. The default settings for
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. These
features include:
• Controller and unit policies, such as Auto Rebuild, Auto Verify, use of
write cache, use of queueing mode, and selection of a StorSave profile.
• Email notification of alarms and other events
• Schedules for when background tasks will be performed, to minimize the
impact on day-to-day performance during peak usage times. (Background
tasks include rebuild, verify, initialize, migrate, and self-test.)
Details about these features are described in this documentation. When you
first set up your controller, you may want to review these sections in
particular:
• “Configuring Your Controller” on page 27
• “Setting Unit Policies” on page 42
• “Setting Background Task Rate” on page 75
Initial Settings for Policies and Background Tasks

Chapter 2. Introducing the 3ware® SATA RAID Controller
Understanding RAID Concepts and Levels
3ware RAID controllers use RAID (Redundant Array of Inexpensive Disks)
to increase your storage system’s performance and provide fault tolerance
(protection against data loss).
This section organizes information about RAID concepts and configuration
levels into the following topics:
• “RAID Concepts” on page 6
• “Available RAID Configurations” on page 7
• “Determining What RAID Level to Use” on page 10
RAID Concepts
The following concepts are important to understand when working with a
RAID controller:
•
Arrays and Units. In the storage industry, the term “array” is used to
describe two or more disk drives that appear to the operating system as a
single unit. When working with a 3ware RAID controller, “unit” is the
term used to refer to an array of disks that is configured and managed
through the 3ware software. Single-disk units can also be configured in
the 3ware software.
•
Mirroring. Mirrored arrays (RAID 1) write data to paired drives
simultaneously . If one drive fails, the data is preserved on the paired
drive. Mirroring provides data protection through redundancy. In
addition, mirroring using a 3ware RAID controller provides improved
performance because 3ware’s TwinStor technology reads from both
drives simultaneously.
•
Striping. Striping across disks allows data to be written and accessed on
more than one drive, at the same time. Striping combines each drive’s
capacity into one large volume. Striped disk arrays (RAID 0) achieve
highest transfer rates and performance at the expense of fault tolerance.
•
Distributed Parity . Parity works in combination with striping on RAID 5.
Parity information is written to each of the striped drives, in rotation.
Should a failure occur, the data on the failed drive can be reconstructed
from the data on the other drives.
Hot Swap. The process of exchanging a drive without having to shut
•
down the system. This is useful when you need to exchange a defective
drive in a redundant unit.
For definitions of other terms used throughout the documentation, see the
“Glossary”.
6 3ware Serial ATA RAID Controller User Guide for Mac OS X
Available RAID Configurations
RAID is a method of combining several hard drives into one unit. It offers
fault tolerance and higher throughput levels than a single hard drive or group
of independent hard drives. RAID levels 0, 1, 10 and 5 are th e most popular.
AMCC's 3ware controllers support RAID 0, 1, 5, 10, JBOD and Single Disk.
The information below provides a more in-depth explanation of the different
RAID levels.
For how to configure RAID units, see “Configuring a New Unit” on page 33.
RAID 0
RAID 0 provides improved performance, but no fault tolerance. Since the
data is striped across more than one disk, RAID 0 disk arrays achieve high
transfer rates because they can read and write data on more than one drive
simultaneously. The stripe size is configurable during unit creation. RAID 0
requires a minimum of two drives.
When drives are configured in a striped disk array (see Figure 2), large files
are distributed across the multiple disks using RAID 0 techniques.
Understanding RAID Concepts and Levels
Striped disk arrays give exceptional performance, particularly for data
intensive applications such as video editing, computer-aided design and
geographical information systems.
RAID 0 arrays are not fault tolerant. The loss of any drive results in the loss of
all the data in that array, and can even cause a system hang, depending on
your operating system. RAID 0 arrays are not recommended for high
availability systems unless additional precautions are taken to prevent system
hangs and data loss.
Figure 2. RAID 0 Configuration Example
RAID 1
RAID 1 provides fault tolerance and a speed advantage over non-RAID disks.
RAID 1 is also known as a mirrored array. Mirroring is done on pairs of
drives. Mirrored disk arrays write the same data to two different drives using
RAID 1 algorithms (see Figure 3). This gives your system fault tolerance by
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.
www.3ware.com 7
Chapter 2. Introducing the 3ware® SATA RAID Controller
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.
The adaptive algorithms in TwinStor technology boost performance by
distinguishing between random and sequential read requests. For the
sequential requests generated when accessing large files, both drives are used,
with the heads simultaneously reading alternating sections of the file. For the
smaller random transactions, the data is read from a single optimal drive head.
Figure 3. RAID 1 Configuration Example
RAID 5
RAID 5 provides performance, fault tolerance, high capacity, and storage
efficiency. It requires a minimum of three drives and combines striping data
with parity (exclusive OR) to restore data in case of a drive failure.
Performance and efficiency increase as the number of drives in a unit
increases.
Parity information is distributed across all of the drives in a unit rather than
being concentrated on a single disk (see Figure 4). This avoids throughput
loss due to contention for the parity drive.
RAID 5 is able to tolerate 1 drive failure in the unit.
Figure 4. RAID 5 Configuration Example
8 3ware Serial ATA RAID Controller User Guide for Mac OS X
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 5). 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. The third and fourth drives are mirrored as a second fault tolerant
array using RAID 1. The two mirrored arrays are then grouped as a striped
RAID 0 array using a two tier structure. Higher data transfer rates are
achieved by leveraging TwinStor and striping the arrays.
In addition, RAID 10 arrays offer a higher degree of fault tolerance than
RAID 1 and RAID 5, since the array can sustain multiple drive failures
without data loss. Please note that if both halves of a mirrored pair in the
RAID 10 array fail, then all of the data will be lost.
Figure 5. RAID 10 Configuration Example
Single Disk
A single drive can be configured as a unit through 3ware software. (3DM 2 or
CLI). Like disks in other RAID configurations, single disks contain 3ware
Disk Control Block (DCB) information and are seen by the OS as available
units.
Single drives are not fault tolerant and therefore not recommended for high
availability systems unless additional precautions are taken to prevent system
hangs and data loss.
Hot Spare
A hot spare is a single drive, available online, so that a redundant unit can be
automatically rebuilt in case of drive failure.

Chapter 2. Introducing the 3ware® SATA 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.
Table 3: RAID Configuration Types
RAID Type Description
RAID 0 Provides performance, but no fault tolerance.
RAID 1 Provides fault tolerance and a read speed advant age over non-
RAID disks.
RAID 5 This type of unit provides performance, fault tolerance, and high
storage efficiency. RAID 5 units can tolerate one drive failing
before losing data.
RAID 10 A combination of striped and mirrored units for fault tolerance
and high performance.
Single Disk Not a RAID type, but supported as a configuration.
Provides for maximum disk capacity with no redundancy.
You can create one or more units, depending on the number of drives you
have installed.
Using Drive Capacity Efficiently
To make the most efficient use of drive capacity, it is advisable to use drives
of the same capacity in a unit. This is because the capacity of each drive is
limited to the capacity of the smallest drive in the unit.
The total unit capacity is defined as follows:
10 3war e Ser ial AT A RAID Con tr oller User Guide for Mac OS X
3ware Tools for Configuration and Management
Table 4: Drive Capacity
RAID Level Capacity
Single Disk Capacity of the drive
RAID 0 (number of drives) X (capacity of the smallest drive)
RAID 1 Capacity of the smallest drive
RAID 5 (number of drives - 1) X (capacity of the smallest drive)
Storage efficiency increases with the number of disks:
storage efficiency = (number of drives -1)/(number of drives)
RAID 10 (number of drives / 2) X (capacity of smallest drive)
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. For more information, see the discussion of drive coercion
under “Creating a Hot Spare” on page 40.
3ware Tools for Configuration and
Management
3ware software tools let you easily configure the drives attached to your
3ware RAID controller, specifying which drives should be used together as a
RAID unit and the type of RAID configuration you want, and designating hot
spares for use if a drive degrades.
3ware provides the following tools for use in configuring and managing units
attached to the 3ware controller:
• 3DM 2 (3ware Disk Manager)
3DM runs in the background on the controller’s host system, and can be
accessed through a web browser to provide ongoing monitoring and
administration of the controller and associated drives. It can be used
locally or remotely.
For details about working with 3DM, see “3DM 2 (3ware Disk Manager)
Introduction” on page 14.
Using 3DM to manage your 3ware RAID controller is discussed
throughout this manual.
www.3ware.com 11
Chapter 2. Introducing the 3ware® SATA RAID Controller
3DM 2 is the current version of the 3ware Disk Manager . Th roughout this
documentation, it is referred to interchangeably as 3DM and 3DM 2.
• 3ware CLI (Command Line Interface)
The 3ware CLI provides the functionality available in 3DM through a
Command Line Interface. You can view unit status and version
information and perform maintenance functions such as adding or
removing drives, and reconfiguring RAID units online. You can also use
it to remotely administer controllers in a system.
The 3ware CLI is described in 3ware Serial ATA RAID Controller CLI
Guide and in the 3ware HTML Bookshelf.
Monitoring, Maintenance, and Troubleshooting Feat ures
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. SMART data is checked on all disk
drives (array members, single disks, and hot spares). Monitoring of
SMART thresholds can be turned on and off in 3DM. (For details, see
“V iewin g SMART Data About a Drive” on page 67.)
•
Verification. The verify task verifies all redundant units, and checks for
media errors on single disks, spares, and RAID 0 unit members. If the
disk drive is part of a redundant unit, error locations that are found and are
deemed repairable are rewritten with the redundant data. This forces the
drive firmware to reallocate the error sectors accordingly. (For more
information, see “About Verification” on page 70.)
•
Error Correction. Bad sectors can be dynamically repaired through error
correction (Dynamic Sector Repair). Reallocation of blocks is based
intelligently on the location of the block in relation to the stripe.
•
Scheduled Background Tasks. Initialize, rebuild, verify, and self-test
tasks can all be run in the background, at scheduled times. This lets you
choose a time for these tasks to be run when it will be least disruptive to
your system. You can also define the rate at which background tasks are
performed, specifying whether I/O tasks should be given more processing
time, or background rebuild and verify tasks should be given more
processing time. (For more information, see “Scheduling Background
Tasks” on page 76.)
•
Write Cache. Write cache can be enabled or disabled using 3DM 2 and
CLI. When write cache is enabled, data will be stored in system cache,
12 3war e Ser ial AT A RAID Con tr oller User Guide for Mac OS X
Monitoring, Maintenance, and Troub leshooting Features
3ware controller cache, and drive cache before the data is committed to
disk. This allows the system to process multiple write commands at the
same time, thus improving performance. However when data is stored in
cache, it could be lost if a power failure occurs. With a Battery Backup
Unit (BBU) installed, the cache stored on the 3ware controller can be
restored. A UPS (uninterruptable power supply) is recommended when
using write cache. (For more information, see “Enabling and Disabling
the Unit Write Cache” on page 43.)
•
StorSave™ Profiles allow you to set the level of protection versus
performance that is desired for a unit when write cache is enabled. (For
more information, see “Setting the StorSave Profile for a Unit” on
page 46.)
•
Drive and Unit Identification. Units or drives in enclosures can be
2
identified by flashing LEDs. When the I
C port on the controller has been
connected to a chassis with a Chassis Control Unit (CCU), such as the
3ware Sidecar, you can issue drive Locate commands that blink the LEDs
for particular drives, so that you can quickly identify which 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. (For more information, see “Setting the Auto
Rebuild Policy” on page 30.)

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. When the 3DM process is running,
you can use your browser to go to 3DM application pages, where you can
view status information about the controller and RAID units, create RAID
units, and perform other administrative and maintenance tasks locally or
remotely.
T wo levels of access to 3DM are provided: user and administrator . Users have
view-only access, and can check the status of drives and units. Administrators
can view and make changes, using 3DM to configure RAID units and
designate hot spares, and to perform maintenance tasks on RAID units.
In this section, information is organized into the following topics:
• Browser Requirements for 3DM
• 3DM 2 can be installed from the 3ware CD that came with your 3ware
RAID controller. You can also download the current version from the
website at http://www.3ware.com/support/download.asp. Details about
the installation are described in “Driver and Software Installation” on
page 165.
• Starting 3DM and Logging In
• Working with the 3DM Screens
• Setting Up 3DM Preferences
For details about the settings and fields on each of the 3DM 2 screens, see
“3DM 2 Reference” on page 88.
For additional information about managing and maintaining 3ware controllers
using 3DM, see the remaining chapters in this guide.
14 3war e Ser ial AT A RAID Con tr oller User Guide for Mac OS X
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.
Note: Because 3DM may be viewed in different browsers, the format and style of
the 3DM browser windows illustrated in this documentation are examples only. The
actual “look” of the windows will depend on the browser you use.
Browser Requirements for 3DM
3DM 2 can be installed from the 3ware CD that came with your 3ware RAID
controller. You can also download the current version from the website at
http://www.3ware.com/support/download.asp. Details about the installation
are described in “Driver and Software Installation” on page 165.
3DM must be installed on the system in which the controller is installed. 3DM
does not have to be installed on a remote system in order to remotely manage
the 3ware controller; you simply enter the correct URL into a browser on the
remote system. You will need to enable remote access first, however.
Starting 3DM and Logging In
Normally after installation, the 3DM process starts automatically when you
start your system.
It is a good idea to leave the 3DM process running on the system that contains
your 3ware RAID controller. That way email alerts can be sent by 3DM, and
administrators can manage the controller remotely , if remote administration is
enabled.
When 3DM is running in the background on your computer, you can access
the 3DM web application through your browser to check status information
and manage your 3ware RAID controller.
If the 3DM process does not start automatically, you can start it manually, as
described under “Starting and Stopping the 3DM Process Manually on the
Macintosh” on page 17. You will know if the process is not running, because
www.3ware.com 15
Chapter 3. 3DM 2 (3ware Disk Manager) Introduction
when you try to use the 3DM web application, you will get a page not found
error.
If you want to check the status of a controller from a different computer, see
“Viewing 3DM Remotely Using a Web Browser” on page 18.
Logging In to the 3DM Web Application
When the 3DM process is running in the background, you can log into the
3DM application pages using a brows er.
Two levels of access are provided:
• Users can check the status of the controller, units, and attached drives.
• Administrators can check status, configure, and maintain the units and
drives on the 3ware controller.
Note: Administrator and User status in 3DM is not related to Administrator/User
settings in the operating system.
To log in to the 3DM web application
1 You can start the 3DM 2 web application in one of the following ways:
• In the Finder, choose
Connect to 3DM2.webarchive.
Applications > AMCC, and then double-click
Your browser will open and go to the URL for 3DM 2.
OR
• Open your browser and enter the URL for your system.
The default URL is http://localhost:888/
You can also replace “localhost” with the IP address of the computer
that contains the 3ware controller. For example:
http://<IP address>:888/
Note: If you receive a page not found message, make sure you
entered the URL correctly. If you did, 3DM may not be running in the
background. You can start it manually, as described under “Starting
3DM on the Macintosh” on page 75.
2 The first time you start 3DM, when the security certificate message
displays, click

Starting and Stopping the 3DM Process Manually on the Macintosh
The 3DM process should start automatically after it has been installed. If it
does not, you can start it manually.
To see if the 3DM process is already running
• Open a Terminal window and type:
ps -ax | grep 3dm2 | grep -v grep
If 3DM is running, you will see it included on the output line that
displays.
To stop the 3DM process so you can restart it
1 In a Terminal window, type:
sudo killall 3dm2
2 When prompted for it, enter your administrator password.
3 Wait for a minute or so before verifying that the process has been
terminated. (It can take a couple of minutes for the process to be stopped.)
www.3ware.com 17
Chapter 3. 3DM 2 (3ware Disk Manager) Introduction
4 Verify that the process has been terminated by typing
ps -ax | grep 3dm2 | grep -v grep
The output line should not include 3DM.
5 If the process is still running, contact AMCC/3ware T echnical Support for
assistance.
To start the 3DM process manually
1 Open a Terminal window and type:
sudo /usr/sbin/3dm2
2 Enter your administrator password, when prompted for it.
The 3DM process starts.
3 Open your browser and enter the URL for your system.
The default URL is http://localhost:888/
You can also replace “localhost” with the IP address of the computer that
contains the 3ware controller. For example: http://<IP address>:888/
Viewing 3DM Remotely Using a Web Browser
When remote administration is enabled on the 3DM 2 Settings page, you can
use 3DM to check status and administer your 3ware RAID controller from a
browser on any computer, over an internet connectio n.
You do not need to install the 3DM software on the remote computer.
To connect to 3DM2 through your web browser
• In the address line of your browser, enter the URL or IP of the system
containing the 3ware RAID controller.
If you do not know the URL or IP for the system, you can contact your
network administrator, or open a Terminal window and type
Note: When using 3DM to access a remote system, the time on the
local system must match the time on the file server. If the time varies
by more than 30 minutes, it will not be possible to remotely monitor
the system (you will not be able to log in). If you are in a different time
zone, you must first change the time of the local system to match the
time of the remote system.

Enclosure Summary page provides lists the enclosures
connected to the controller and lets you drill down for more detailed status
information about each.
3DM 2 Settings page lets you set preferences, including email
The
notification for alarms, passwords, page refresh frequency, whether remote
access is permitted, and the incoming port which 3DM will use for listening.
Help lets you access information about using 3DM. The Help is context-
sensitive, so you first see information about the page you now have in view. A
Table of Contents and Index are available to help you find other information.
