Supported RAID Types

RAID is an acronym for either Redundant Array of Independent
Disks or Redundant Array of Inexpensive Disks. The goal of RAID
is to provide higher capacity, performance and/or reliability from
combinations of disk drives than it is practical to achieve with a
single drive.

1-2

Introduction

Adaptec RAID controllers support the following types of array:

RAID-0

A RAID-0 is created by striping data across two or more disk
drives. Simple striping like this creates no redundancy to protect
the data, but by sharing the load equally across multiple drives, it
does provide the best read and write performance of any RAID
type.

RAID-1

A RAID-1 must contain only two disk drives. All data stored on the
array is written to both drives. This duplication, or mirroring, of
the data provides redundancy, ensuring that if one drive fails no
data loss will occur.

1-3

Adaptec SCSI RAID 2120S/2200S Software User’s Guide

The cost of this redundancy is inefficient use of capacity, because
all data is written to both drives, only half of the total capacity is
available.

RAID-1 offers no write performance advantage over a single drive,
but read performance benefits from being able to share the load
between two drives.

RAID-5

A minimum of three drives is required to create a RAID-5. Like a
RAID-0, data is striped across the drives, however in the case of a
RAID-5, the capacity of one drive is used to store parity
information. The controller generates this parity data every time
data is written to the array, and it is distributed in stripes across all
the drives.

In the event of a drive failure, the contents of the failed drive can be
rebuilt from the data and parity on the remaining drives.

Using parity minimi zes the cap acity cost of redundancy. Since only
one drive is used to store parity, the worst case of a three-drive
RAID-5 only loses one third of the total capacity, for arrays with
more drives the lost capacity is smaller .

RAID-5 write performance is limited by the need to generate parity
data for every write. Read performance is good because the load is
spread equally across all the drives.

Introduction

RAID-10

A RAID-10 is an example of a dual-level array and is created by
using two or more equal-sized RAID-1s to create a RAID-0.

Second-Level Arrays

The top level RAID-0 shares the load among the second level
RAID-1s, improving both read and write performance. Since
second level arrays are RAID-1, only half the total capacity of the
drives in the array is available.

Second-Level Arrays

The top level RAID-0 shares the load among the second-level
RAID-5s, improving both read and write performance. The second
level RAID-5s use of parity provides efficient redundancy.

Simple Volume

A simple volume consists of a single disk drive.

Spanned Volume

A spanned volume is created by joining two or more disk drives.
The drives do not have to be of equal capacity and are connected
end-to-end. A spanned volume offers no redundancy and no
performance advantage over a single drive.

1-6

Introduction

RAID Volume

A RAID volume is created by joining two or more single-level
arrays of the same RAID type. Unlike dual-level arrays, the arrays
in a RAID volume do not have to be of equal capacity. In direct
contrast to dual-level arrays, the second-level arrays in a RAID
volume are not striped together, instead they are connected end-to­end.

Features

Optimized Disk Utilization

For simplicity the explanations of the various types of array above
describe the arrays in terms of complete drives. Typically arrays
use the same size drives, or if drives of varying capacities are used,
the capacity used on each drive is limited to that of lowest capacity
drive.

For example, a RAID-1 constructed using one 18G and one 9G
drive will only use half of the capacity of the larger drive and the
array will be limited to 9G.

Adaptec’s Optimized Disk Utilization feature allows arrays to be
created using portion of drives. These sections of drives are known
as segments and are created automatically during the array
creation process.

Within a given array each segment will be the same size, but the
segment size does not have to equal the capacity of the smallest
drive.

Any unused capacity on drives is known as available space, and
can be used in another array or arrays.

Adaptec RAID controllers use a small segment at the beginning of
each drive connected to them to store information about the drives
and arrays attached to the controller. This area is known as the
RAID signature.

Array Reconfiguration

Adaptec RAID controllers support modifying existing arrays by
expansion, migration from one array type to another and changing
the stripe size.

1-7

Adaptec SCSI RAID 2120S/2200S Software User’s Guide

Table 1-1 lists the RAID type migrations supported by Adaptec

Storage Manager.

Table 1-1 Supported Array Migrations

Current Array Type New Array Type

RAID-0 RAID-5 or 10
RAID-1 RAID-0 or 5 or 10
RAID-5 RAID-0 or 10
RAID-10 RAID-0 or 5
RAID-50 RAID-0 or 5 or 10

See Chapter 3, Adaptec Storage Manager-Browser Edition, for
instructions on modifying arrays.

Some operating systems, for example Windows XP, Windows
2000, Windows NT and Novell Netware, support Online Capacity
Expansion (OCE). That is, on completion of an array expansion, the
additional capacity can be used without rebooting the system.
Refer to your operating system documentation for instructions on
using the additional capacity.

Drive Enclosures

Adaptec RAID controllers support drive enclosures that include
either SES or SAF-TE enclosure management hardware.

Hot Spares

A hot spare is a drive that is reserved to replace a failing drive in a
redundant array. In the event of drive failure, the hot spare will
replace the failing drive and the array will be rebuilt.

Adaptec RAID controllers support two types of hot spares:

■ Global—protects every array that the drive has eno u gh

available capacity to protect.

■ Dedicated—protects only the array that it has been assigned to

protect.

1-8

Introduction

Automatic Rebuild On Replacement

Adaptec RAID controllers support a feature known as Automatic
rebuild on replacement. This may be useful in the event of a drive
failure if no hot spare is available and the failing drive is in an SES
or SAF-TE enabled drive enclosure.

When this feature is enabled (default) a rebuild of any redundant
array that the failed drive was a member of will be triggered
automatically by simply removing the failur e drive and r eplacing it
with a new drive.

SCSI Devices Supported

In addition to SCSI hard disk drives, Adaptec RAID controllers
support a wide range of SCSI devices, from CD-ROMs and tape
drives to scanners and removable media drives.

Supported Controllers

The majority of this chapter and all the other documentation
supplied with your controller describes the capabilities of the
RAID controllers listed in the left column of Table 1-2. Adaptec
Storage Manager-Browser Edition also supports other Adaptec
RAID controllers provided the RAID management software
supplied with those cards, Adaptec Storage Manager or Adaptec
Storage Manager Pro is already installed on the system.

The Adaptec RAID Configuration Utility (ARC) is an embedded
BIOS utility that includes an Array Configuration Utility (ACU)
that allows the creation, configuration, and management of arrays.
Also included are SCSISelect which supports changing SCSI device
and controller settings, and Disk Utilities to low-level format or
verify disk media.

Adaptec also provides a standalone utility to create, configure, and
manage arrays from an MS-DOS prompt. This utility is called
Array Configuration Utility (ACU) for MS-DOS and it is described
in the Adaptec SCSI RAID Software Reference Guide. This chapter
describes only the functionality of the BIOS-based ACU.

To run ARC, when prompted by the following message during the
system boot process press Ctrl+A :

Press <Ctrl><A> for Adaptec RAID Configuration Utility

2-1

Adaptec SCSI RAID 2120S/2200S Software User’s Guide

The Adaptec SCSI RAID Controller menu appears, presenting the
following options:

■ Array Configuration Utility

■ SCSISelect Utility

■ Disk Utilities

To select an option from this menu or from any of the menus
within ARC, move the cursor to the option with the Up/Down
arrow keys and press Enter. In some cases, selecting an option
displays another menu. You can return to the previous menu at
any time by pressing Esc.

The following sections discuss each of these menu options.

Using the Array Configuration Utility

The Array Configuration Utility (ACU) enables you to manage,
create, and delete arrays from the controller’s BIOS. You can also
initialize and rescan drives.

You can use the ACU to create a bootable array for the system. We
recommend that you configure the system to boot from an array
instead of from a single disk to take advantage of the redundancy
and performance features of arrays. For details on creating a
bootable array, see Deleting Arrays on page 2-4.

Note: If you are changing the configuration of a system tha t i s

already in use on a network, log all users off the system and
shut it down in an orderly manner before you start the ACU.

Managing Arrays

Use the Manage Arrays option to view array properties and
members, make an array the boot array, manage failover
assignments, and delete arrays. The following sections describe
these operations in greater detail.

Viewing Array Properties

To view the properties of an existing array:

1 At the BIOS prompt, press Ctrl+A.

2-2

Using Adaptec RAID Configuration

2 From the ARC menu, select Array Configuration Utility.
3 From the ACU menu, select Manage Arrays.
4 From the List of Arrays dialog box, select the array you want to

view information on and press Enter.
The Array Properties dialog box appears, showing detailed

information on the array. The physical disks associated with the
array are displayed here, except in the case of dual-level arrays
(RAID 10 and RAID 50, for example). For dual-level arrays,
highlight the displayed member and press Enter to display the
second level. Press Enter again to display the physical disks
associated with the array.

Note: A failed drive is displayed in a different text color.

5 Press Esc to return to the previous menu.

Making an Array Bootable

You can make an array bootable so that the system boots from the
array instead of from a stand-alone (single) disk.

To make an array bootable:

1 At the BIOS prompt, press Ctrl+A.
2 From the ARC menu, select Array Configuration Utility.
3 From the ACU menu, select Manage Arrays.
4 Select the array you want to make bootable and type Ctrl+B.

This changes the selected array’s number to 00, making it the
controller’s boot array.

5 Reboot the system.

If you are booting from the controller, bear in mind the following:

■ If the controller is not a boot device, you can disable its runtime

BIOS, see page 2-11. When the BIOS is disabled it will not
occupy any of the expansion ROM region of the system’s
memory map. This may be useful if there are several cards with
an expansion ROM (BIOS) in the system.

2-3

Adaptec SCSI RAID 2120S/2200S Software User’s Guide

!

!

■ You cannot make a non-00 array bootable if the array is in a

build/verify or reconfiguration process.

Caution: The controller always uses the lowest numbered

array as its bootable array. If you delete array 00 for any
reason, the next lowest numbered array will become the
bootable array. Use the Ctrl+B option to mark the correct
array as the bootable array (by making it array 00).

If you want to boot from a stand-alone (single) disk drive, first
create a volume on that disk.

The system BIOS provides additional tools to modify the boot
order. For more information, refer to your system documentation.

Deleting Arrays

Caution: Back up the data on an array before you delete it. All

data on the array is lost when you delete the array. Deleted
arrays cannot be restored.

To delete an existing array:

1 At the BIOS prompt, press Ctrl+A.
2 From the ARC menu, select Array Configuration Utility.
3 From the ACU menu, select Manage Arrays.
4 Select the array you wish to delete and press Delete.
5 In the Array Properties dialog box, press Delete again and

press Enter. The following prompt is displayed:

Warning!! Deleting will erase all data from the
array.
Do you still want to continue? (Yes/No):

6 Press Yes to delete the array or No to return to the previous

menu. At the Array Properties dialog box, select Delete again
and press Enter.

7 Press Esc to return to the previous menu.

Managing Failover Drive Assignments

To assign a hot spare drive to an array:

1 Select Manage Arrays from the Main menu.
2 On the List of Arrays dialog box, select the array you want to

assign a hot spare drive to, and type Ctrl+S. The Hotspare

Management for Array dialog box is displayed, which shows

the drives that can be assigned as hot spare drives.

3 Select a drive and press the Insert key to assign the drive as a

hot spare. The specified drive is displayed in the Assigned

Hotspares drives list.

4 Press Enter to save the hot spare drive assignment. The

following prompt is displayed:

Have you finished managing Hotspare drives?

5 Type Y (yes) to return to the Main menu.

To remove an assigned hot spare drive from an array:

1 Select Manage Arrays from the Main menu.
2 In the List of Arrays dialog box, select the array from which

you want to remove the assigned hot spare drive and type

Ctrl+S. The Hotspare Management for Array dialog box is

displayed, which shows a list of drives that can be assigned as

hot spare drives and a list of drives that are assigned as hot

spare drives.

3 From the Assigned Hotspares drives list, select the drive to

be removed, then press Delete. The specified drive is

displayed in the Select Hotspares drives list.

4 Press Enter to save the removed hot spare drive assignment.

The following prompt is displayed:

Have you finished managing Hotspare drives?

5 Type Y (yes) to return to the Main menu.

Adaptec SCSI RAID 2120S/2200S Software User’s Guide

Creating Arrays

Before creating arrays, make sure the disks for the array are
connected and installed in your system (or enclosure). Note that
any disks with MS-DOS partitions, disks with no usable space, or
disks that are uninitialized appear dimmed and cannot be used for
creating a new array. For information on how to initialize a disk
drive, see page 2-9.

To create an array:

1 Shut down and reboot the system.
2 At the BIOS prompt, press Ctrl+A.
3 From the ARC menu, select Array Configuration Utility.
4 From the ACU menu, select Create Array.
5 Use the Left/Right arrow keys to select a channel.
6 Select the disks for the new array and press Insert. ACU

displays the largest usable space available for each disk. You
can use available space from multiple disks for the new array.

Note: Consult Table 2-1 on page 2-7 for the maximum

number of drives that can be used for each RAID level.

To deselect any disk, highlight the disk and press Delete.

Note: ACU cannot reliably find disks or enclosures that

were powered up after system power-up.

7 Press Enter when all disks for the new array are selected. The

Array Properties menu displays.

If you install a controller into a system that has been powered
down, on startup the BIOS will announce the detected
configuration changes. If the controller does not consider these
changes risky it will present a confirmation prompt and will auto­confirm if there has been no operator input in 30 seconds. If the
controller considers that the changes are risky, you will be
prompted for further action.

2-6

Using Adaptec RAID Configuration

Assigning Array Properties

Note that you cannot change array properties from the ACU once
the array is created. To change array properties once the array is
created, use Adaptec Storage Manager.

To assign properties to the new array:

1 In the Arra y Properties menu, select an array type and press

Enter. Note that only those array types available according to

the number of drives selected are displayed. For a description of
the supported array types, see the installation guide shipped
with your controller.

The physical SCSI limitation for the controller is 15 drives per
channel. The maximum number of drives allowed and
minimum number of drives required depends on the RAID
level. Consult Table 2-1 for a listing of this information.

2 Type in an optional label for the array and press Enter.
3 Enter the desired array size. The maximum array size available

based on the segments you selected is displayed automatically.
If you want to designate a different array size, type the desired
array size and select MB (megabytes), GB (gigabytes), or TB
(terabytes) from the drop-down list. If the available space from
the selected segments is greater than the size specified, the
remaining space will be available for use in other arrays.

2-7

Adaptec SCSI RAID 2120S/2200S Software User’s Guide

4 Sel e ct the desired stripe size. The allowable stripe sizes are 16,

32, and 64 KB (the default). For RAID 50 arrays, 64 KB is the
only stripe size supported by ACU. The default stripe size gives
the best overall performance in most network environments.

5 Specify whether you want to enable read caching for the array.

This option should always be enabled to optimize performance,
unless your application is doing completely random reads,
which is unlikely.

6 Specify if you want to enable write caching for the array.

Note: By design, some controllers do not allow the use of

write caching. In such cases, the controller will not activate
write caching, regardless of the write cache setting. If this
is the case a message will be displayed that tells you the
settings have been recorded but have no effect.

Write caching options (if supported) consist of the following:

■ Enable when protected—If supported, enables the write

cache only when a battery is present and the battery’s char ge
status is OK.

■ Enable always—If supported, enables the writ e cach e even

if no battery is present or the battery’s charge status is not
OK. Note that setting an array’s write cache property to
Enable always might result in data loss or corruption if
power to the controller is lost when no battery is present or
the battery loses its charge.

■ Disable—Disables use of the write cache.

7 When you are finished, press Done.

Initializing Disk Drives

If an installed disk does not appear in the disk selection list for
creating a new array or if it appears grayed out, you may have to
initialize it before you can use it as part of an array.

Caution: Initializing a disk overwrites the partition table on

the disk and makes any data on the disk inaccessible. If the
drive is used in an array, you may not be able to use the array
again. Do not initialize a disk that is part of a boot array. The
boot array is lowest numbered array (normally 00) in the List
of Arrays dialog box.

See Viewing Array Properties on page 2-2 for information on
determining which disks are associated with a particular
array.

To initialize drives:

1 At the BIOS prompt, press Ctrl+A.
2 From the ARC menu, select Array Configuration Utility.
3 Select Initialize Drives.
4 Use the Right/Left arrow keys to select a channel.
5 Use the up and down arrow keys to highlight the disk you wish

to initialize and press Insert.

6 Repeat step 5 until all the drives to be initialized are selected.
7 Press Enter.
8 Read the warning message and ensure that you have selected

the correct disk drives to initialize. Type Y to continue.

Rescanning Disk Drives

To rescan the drives connected to the controller:

1 At the BIOS prompt, press Ctrl+A.
2 From the ARC menu, select Array Configuration Utility.
3 Select Rescan Drives.

Using the Controller Configuration Utility

To access the Controller Configuration Utility:

1 When you turn on or reboot your system, press Ctrl+A to access

ARC when prompted by the following message:

Press <Ctrl><A> for Adaptec RAID Configuration Utility

2 If multiple controllers are installed, select the controller you

want to configure and press Enter.

3 From the ARC menu, select SCSISelect Utility.

The Controller Configuration and SCSI Configuration menu
options are displayed.

4 Select Controller Configuration.

You can modify the following Controller Interface Definitions:

■ Drives Write Cache — Enables or disables the write-back

cache feature of all SCSI disk drives connected to the
controller. If Disabled, the controller will disable the write­back cache of all attached drives. If Enabled, then the
controller will enable the write-back cache of all attached
drives. If Drive Default, then the controller will not change
the write-back cache setting of any attached drives. The
default is Drive Default.

Caution: Disk drives with write-back cache enabled do

not have the benefit of battery protection and could

lose or corrupt data as a result of unexpected power
loss or drive removal.

Certain controllers may not support drives write cache. In
those cases where drives write cache is not supported,
setting the option to Enabled has no effect.

■ Runtime BIOS — Enables or disables the controller’s

runtime BIOS. The BIOS must be enabled if you want to boot
from the controller.

2-11

Adaptec SCSI RAID 2120S/2200S Software User’s Guide

If Runtime BIOS is enabled and the BBS Support and Array­based BBS Support options are disabled, the controller

BIOS is enabled and will post the lowest numbered array
(typically 00) on the first controller found as a legacy Int13h
bootable hard disk drive.

The default is Enabled.

■ Automatic rebuild on replacement — If enabled, this option

lets you replace a failed drive in the same enclosure slot in a
RAID 1, RAID 5, RAID 10 or RAID 50. Then the BIOS
recognizes that the failed drive has been replaced, initializes
the new disk, and immediately initiates a failover. Note that
this option is supported only for disks in SAF-TE enclosures
or backplanes.

The default is Enabled.

■ Array Background Consistency Check — If enabled, this

option forces the controller to constantly check all portions
of disks used by all arrays to see if the disks can return data
from the blocks. On a fully-redundant RAID 5 with no bad
segments, the controller repairs any data that cannot be
read.

The default is Disabled.

■ BBS Support — If the Runtime BIOS option and this option

are enabled and the Array-based BBS Support option is
disabled, the lowest numbered array on each controller is
posted as a BBS (BIOS Boot Specification) device.

The default is Enabled.

■ Array-based BBS Support — If Runtime BIOS, BBS

Support and this option are all enabled, the lowest

numbered three devices (typically 00, 01 and 02) on each
controller in the system are posted as BBS devices.

In a BBS-enabled system with two controllers installed, and
at least three arrays on each controller, if Array based BBS
support is enabled the “Hard drive boot order menu” will
include six entries for arrays connected to the two RAID
controllers.

2-12

Using Adaptec RAID Configuration

The Ctrl-B option in ACU moves any array to be array 00.
Using this option repeatedly allows any boot order to be
chosen.

The default is Disabled.

■ Physical Drives Display during POST— The default is

Disabled.

■ CD-ROM Boot Support — The default is Enabled.

■ Removable Media Devices Support — The default is

Enabled.

■ Alarm Control — The default is Enabled.

You cannot set the following options:

■ NVRAM State — Displays the current status of the NVRAM

cache. This option is available only for controllers that have
a battery and is for display only. In normal operation it will
display Clean.

■ Controller Memory Size — Displays the amount of memory

installed on the controller.

Using the SCSI Configuration Utility

2-13

Adaptec SCSI RAID 2120S/2200S Software User’s Guide

5 The Se lect SCSI Channel menu is displayed. Select the

appropriate channel from this menu.
You can modify the following SCSI Channel Interface

Definitions:

■ Controller SCSI Channel ID — Sets the controller’s SCSI

ID. We recommend that you leave the controller set to SCSI
ID 7, which gives it the highest priority on the SCSI channel.

■ SCSI Parity Checking — Determines whether the controller

verifies the accuracy of data transfer on the SCSI channel.
You should disable SCSI Parity Checking on the controller
and all SCSI devices if any SCSI device supported by the
controller does not support SCSI parity; otherwise, leave it
enabled. Most SCSI devices do support SCSI parity. If you
are not sure whether a device supports SCSI parity, consult
the documentation for the device.

■ Controller SCSI Channel Termination — Sets termination

on the controller card. We recommend that you leave the
default setting of Auto Mode.

■ SCSI Device Configuration — For information about these

options, see the section, SCSI Device Configuration Options.

SCSI Device Configuration Options

The SCSI device settings allow you to configur e certain paramete rs
for each device on the SCSI channel. To configure settings for a
specific device, you must know the SCSI ID assigned to that device.
If you are not sure of the SCSI ID, see Using the Disk Utilities on

page 2-15.

■ Maximum Transfer Rate — Determines the maximum data

transfer rate that the SCSI channel supports. The maximum
effective data transfer rate is doubled when Initiate Wide
Negotiation is set to Yes and 16-bit devices are attached. (Initiate
Wide Negotiation has no ef fect with 8-bit devices.)

■ Enable Disconnection — Determines whether the SCSI channel

allows the SCSI device to disconnect from the SCSI channel
(sometimes called Disconnect/Reconnect or Reselection). This
option should be enabled for maximum performance. The
default is yes.

2-14

Using Adaptec RAID Configuration

■ Initiate Wide Negotiation — Determines whether the SCSI

channel attempts 16-bit data transfer instead of 8-bit data
transfer. The effective data transfer rate is doubled when 16-bit
data transfer is used. The default is yes.

■ QAS — Determines whether QAS (Quick Arbitration and

Selection) is used to eliminate overhead and speed up data
transfers on the SCSI bus. The default is yes.

■ Packetized — Determines whether SCSI packetization

(encapsulation) is used to reduce overhead and speed data
transfer. The packetized SCSI protocol provides a method for
transferring command and status information at the maximum
rate. The default is yes.

Using the Disk Utilities

The BIOS-based Disk Utilities enable you to low-level format or
verify the disk media of your SCSI hard disks.

To access the disk utilities:

1 When you turn on or reboot your system, press Ctrl+A to access

the Adaptec RAID Configuration (ARC) utilities when
prompted by the following message:

Press <Ctrl><A> for Adaptec RAID Configuration Utility

2 If multiple controllers are installed, select the controller you

want to configure and press Enter.

3 From the ARC menu, select Disk Utilities.
4 Select the desired channel and press Enter.

After the option is selected, a list of all SCSI IDs and the devices
at each ID is displayed. After selecting a specific ID and device,
a small menu appears, displaying the following options:

■ Format Disk—Performs a low-level format on a hard disk

drive. Each hard disk drive must be low-level formatted
before you can use your operating system’s partitioning and
file preparation utilities, such as MS-DOS Fdisk and Format.

Most SCSI disk devices are preformatted at the factory and
do not need to be formatted again. The Format Disk option
is compatible with the vast majority of SCSI disk drives.

2-15

Adaptec SCSI RAID 2120S/2200S Software User’s Guide

!

The controller should not be powered of f or rebooted dur ing
a disk format. Doing so may render the disk unusable until
the format is manually restarted and completed.

Caution: A low-level format destroys all data on the

drive. Be sure to back up your data before performing
this operation. Once started, you cannot abort a low­level format.

■ Verify Disk Media — Scans the media of a disk drive for

defects. If the utility finds bad blocks on the media, it
prompts you to reassign them. If you select yes, the utility
remaps the recoverable defects and no longer uses those
blocks. You can press Esc at any time to abort the utility.

Viewing the Event Log

The BIOS-based event log stores all firmware events (configuration
changes, array creation, boot activity, and so on).

To access the event log:

1 When you turn on or reboot your system, press Ctrl+A to access

the ARC when prompted by the following message:

Press <Ctrl><A> for Adaptec RAID Configuration Utility

2 If multiple controllers are installed, select the controller you

want to configure and press Enter.

3 From the ARC menu, press Ctrl+P.
4 The Controller Service Menu appears, including the option

Controller Log Information.

5 Select Controller Log Information and press Enter. The current

log is displayed.

About Adaptec Storage Manager

Adaptec Storage Manager - Browser Edition is a web-based
application that supports managing storage either locally (at the
system in which the storage controller is installed), or remotely
(from another system).

Any system containing an Adaptec storage controller that has
Windows or Linux and a supported browser installed can be
managed locally. Supported browsers are:

■ Windows

■ Internet Explorer (IE) 5.0 or later

■ Netscape 6 or later

■ Linux

■ Adaptec-supplied and installed version of Mozilla

■ Netscape 6 or later

These same Windows and Linux systems can also be managed
remotely. This can be achieved in tw o w ay s:

■ Installing Adaptec Storage Manager on the remote system.

■ Directing the browser on the remote system to the system you

want to manage.

Note: If you want to manage from a Linux system it is

recommended that you install Adaptec Storage Manager on
the remote system and use the Adaptec-supplied version of
Mozilla as the browser.

For Unix and NetWare installations, Adaptec Storage Manager can
only be used to manage the system remotely. Local management is
supported using the CLI.

The following explanation of the software architecture will help
you understand the possible configurations and determine which
one is most appropriate for your application. Installation
instructions are included in the Adaptec SCSI RAID Installation
Guide supplied on the same CD as this document.

3-2

Adaptec Storage Manager-Browser Edition

Adaptec Storage Manager - Browser Edition consists of the three
major components:

■ A supported web browser, which should already be installed

on the system.

■ The Adaptec web service which supplies content displayed on

the web browser.

■ An Adaptec-supplied storage agent.

For a locally managed system, all three components will be
installed on the same system.

To support the remote management configurations described
below, all components must be installed on systems that have a
TCP/IP connection through which the other component(s) can be
accessed.

All communication uses Secure-HTTP (S-HTTP) or SSL protocols
to encrypt all data transmitted and ensure security. Connection
over an Ethernet network, a corporate WAN, or VPN are
supported.

Several remote management configurations are possible:

■ The browser will always be on a remote system.

■ The storage agent will always be installed on the system with

the storage controller installed.

■ The web service can be installed on the same remote system as

the browser, the system with the storage controller installed on
a third system.

The storage agent is supplied for all supported operating systems,
while the web service is available only for Windows and Linux. In
order for Adaptec Storage Manager - Browser Edition to manage
storage on a UNIX or NetWare system, the storage agent must
communicate with the Adaptec web service on a separate
Windows or Linux system.

In this configuration, the Windows or Linux system can either be
used to manage the RAID controller, or act as a server
communicating with a supported browser on a third system.

Understanding Adaptec Storage Manager

Shown below is an example of a typical Adaptec Storage Manager
screen.

.

Note: Depending on your operating system, browser , and

color scheme you may notice some differences between this
illustration and your screen.

At the top of the Adaptec Storage Manager screen is the header
frame. In this area is the name of the system that you are currently
connected to and a number of buttons that perform various actions
or open additional windows.

The action buttons are Logout and Rescan. Selecting Logout will
end your session and return you to the Login screen.

Use the Rescan button to have Adaptec Storage Manager re-read
the configuration of the system. Typically, when a rescan is
required, it will occur automatically, for example, after an array is
created.

It is possible for the system configuration to change without
Adaptec Storage Manager being notified. For example, drives
inserted/removed from a non-intelligent enclosure or an enclosur e
powered on after you logged in to Adaptec Storage Manager.

The remaining buttons: Events, Options, Help, Properties, and
Tasks open additional windows that provide more detailed
information, allow you to perform actions or change settings on a
specific aspect of your storage subsystem.

3-7

Adaptec SCSI RAID 2120S/2200S Software User’s Guide

For detailed instructions on using these buttons, see the sections

Viewing Events on page 3-20, User Interface Options on page 3-19,
Help on page 3-20, Displaying and Modifying Properties on page 3-21,

and Viewing and Creating Tasks on page 3-27.
Immediately following the header frame is a controller information

line including the model number of the first Adaptec storage
controller found in the system and the amount of cache memory
installed on that controller.

Beneath the controller information are Physical Devices and
Logical Devices views that show connected devices and existing
arrays on this controller. Click the button to compress the
information displayed for this controller. Controller information
and device views are repeated for each additional Adaptec storage
controller in the system.

Select the controller by clicking anywhere on the controller
information. When the controller is selected, the Events, Properties
and Tasks buttons change from blue to amber, indicating that
clicking any of them will bring up an additional window with
information and options specific to this controller.

Pop Up Tool Tips

If you position the cursor over a device or button a pop-up tool tip
appears. For buttons, the tips contain helpful information about the
function of the button, while for devices they display additional
information.

Physical Devices

The Physical Devices view displays information about the drives
and enclosures attached to the Adaptec storage controller. The
devices are shown organized by the channel that they are
connected to and shown in numerical order.

The display for each channel includes information on maximum
speed capability, the number of the channel on the controller, and
the number of devices found (excluding the SCSI controller).

Selecting a channel or device will turn the Events, Properties, and
Tasks buttons amber. This indicates that clicking any of these
buttons will bring up an additional window with information and
options specific to that device or channel.

3-8

Adaptec Storage Manager-Browser Edition

At the top of the Physical Devices view, grouped to the right of
View, are three view selection buttons . These buttons

select how Adaptec Storage Manager displays the physical devices
connected to this controller.

Hot Spares

Click the Hot Spare button to configure a drive or drives
as hot spares. Hot spare drives are assigned to protect redundant
arrays in the event of a drive failure. If a drive fails in a redundant
array protected by a hot spare, the array will be rebuilt using the
hot spare to replace the failing drive.

A hot spare can be assigned to protect a single array or all the
arrays on the controller.

Changing How Drives are Displayed

When Adaptec Storage Manager is loaded, the Physical Devices
view will default to display a condensed view of the controller
configuration which hides detailed information about the drives.
More information is available by either positioning the mouse
pointer over the device or clicking on the arrowhead to the left of a
row of devices.

The selected display mode button will appear in a lighter shade of
blue than the other two buttons. The default display is the Text
Description View , but in the condensed view used when
Adaptec Storage Manager is loaded, the display is the same in all
three modes.

If you change the display mode by selecting one of the other view
buttons, a yellow arrow will flash to the left of any devices where
the current condensed display prevents Adaptec Storage Manager
from showing all the information available.

An icon is always the first entry on each device line. The icon is
used to represent a hard disk drive. If a + symbol appears with the
hard disk drive icon , the drive is a hot spare. Different icons are
used to represent other devices.

3-9

Adaptec SCSI RAID 2120S/2200S Software User’s Guide

View

is the default display mode and when expanded, will show the

following information about each device:

■ Capacity of the drive

■ Drive manufacturer and model number

■ SCSI drive ID

When expanded, the Full Size Capacity View button and the
Relative Size Capacity View button represent each drive as a

bar. A drive that is not used as part of any array is shaded blue
surrounded by a dotted line.

displays a full-length bar for each drive, regardless of capacity.

displays a bar for each drive, with the largest capacity drive
full-length and the other drives proportional to the drive capacity,
relative to the largest drive.

Any part of a drive used in an array is shown as a gray segment
within the bar. Selecting any gray segment will highlight it in
amber and, in the Logical Devices view, highlight the array of
which this segment is a member.

In either the Full Size Capacity View or the Relative Size Capacity
View, a small portion at the end of the drive is shown in dark gray.

The segment at the end of the drive may vary in size from drive to
drive because, in addition to the RAID signature, the controller
also limits the usable capacity of each drive to increments of 100
MB.

This is done because hard disk drives of apparently the same
capacity from different manufacturers, or even different models
from the same manufacturer, actually vary slig htly in the true
capacity available. Although, in normal operation this is not an
issue, it can be when assigning hot spares or replacing a failed
drive.

If the controller used the maximum capacity of each drive and a
hot spare or replacement drive was just a few megabytes smaller, it
would not be able to replace the failed drive. By rounding drive
capacities down to the nearest 100 MB, this possibility i s ef fectively
eliminated.

3-10

Adaptec Storage Manager-Browser Edition

Logical Devices

As described earlier, when Adaptec Storage Manager loads, the
Logical Devices view is expanded and you can see the arrays
present on the controller.

At the top of this view are the following buttons: Create, Modify,
and Delete. Each button opens a wizard that wi ll take you thro ugh,
respectively, the steps necessary to create a new array, modify an
existing array, and delete existing arrays on this controller.

Modify allows you to:

■ Change an array from one RAID level to another

■ Expand an array

■ Change the stripe size for a RAID-0, 5, 10 or 50

For detailed instructions on using these buttons, see the sections

Creating Arrays on page 3-12, Deleting Arrays on page 3-17, and
Modifying Arrays on page 3-17.

The main area of the Logical Devices view is used to display the
arrays on this controller. It defaults to a condensed view of top
level arrays. For information on top and second-level arrays, refer
to Supported RAID T ypes on page 1-2.

Note: The Options button allows you to display second-level

arrays if you prefer.

In this condensed view, the RAID level of each device as well as
whether it is protected by a hot spare, is visible.

If a global hot spare exists, all arrays that the hot spare is large
enough to protect will show as protec ted.

In the expanded view, the icons for the arrays are arranged
vertically and alongside them are the capacity, name and type of
array.

Selecting an array by clicking on it will highlight the following in
amber:

■ All the drives or segments that form the array in the Physical

Devices view.

3-11

Adaptec SCSI RAID 2120S/2200S Software User’s Guide

■ Any second-level arrays that form a top-level array in the

Logical Devices view.

■ The Events, Properties, and Tasks buttons in the header frame.

This indicates that selecting any of these three buttons will
bring up an additional window with information and options
specific to that array.

Creating Arrays

Before you use Adaptec Storage Manager to create an array, make
sure that you understand the different types of ar rays supported,
as described in Supported RAID Types on page 1-2, and the type of
arrays that are most appropriate for your application.

Click Create to open the Create Array wizard. This wizard offers
the following options:

■ Create arrays using default settings.

■ Expand the wizard by clicking on Advanced to see additional

options and customize settings.

Using the default settings will create an array of the largest
possible capacity on the selected drives, use the default cache
setting and, if appropriate, the default stripe size.

To create an array using default settings:

1 Open the Create Array wizard by clicking Create for the

controller on which you want to create an array.

2 Select the type of array you want to create in Step 1 of 3 in the

Create Array wizard. Then click Next to move to Step 2 of 3.

3 Click the drives you want to include in the array. Selected

drives will display an amber check mark. When you have
completed your selection click Next to move to Step 3.

Note: The check marks will flash until you have selected

enough drives to create this type of array.

3-12

Adaptec Storage Manager-Browser Edition

!

4 Now you can accept the default name for the new array or enter

one of your choice. The name you choose must be unique, and
can be up to 15 standard ASCII characters in length.

5 When you click Finish, the system will create the new array. Advanced Options

Creating an array by clicking Advanced in the Cr eate Array wizard
follows the same basic process as the previous instructions, but at
each step there are additional options for you to use.

Step 1 of 3 in the Advanced area of the Create Array wizard offers
the following additional options:

■ Spanned Volumes and RAID Volumes—As described in

Chapter 1, Introduction, a spanned volume concatenates segments

from two or more drives to form a volume, while a RAID volume
concatenates two or more arrays of the same type.

■ Enable or Disable Write Caching—When write caching is

enabled, the controller stores the data in cache memory on the
controller and will accept another write to this array as soon as
the data from the previous write is safely stored in the
controller’s memory.

Since writing data to memory is much faster than writing it to
the drives, enabling write caching can significantly improve
performance. All data stored in the cache will be written to the
drives when it is most efficient for the controller.

On controllers fitted with a battery, the additional choice
“Enable when protected by battery” is available. Choosing this
option will enable write caching whenever the battery is
operating correctly, and in the event of a power failure the
battery will protect the data currently in cache.

Caution: Default setting for write cache is enabled. This

setting provides the best performance, but in the event of
power failure there is a risk of data loss.

3-13

Adaptec SCSI RAID 2120S/2200S Software User’s Guide

■ Enable Or Disable Read Caching—When enabled, the

controller will monitor read accesses to this array to try to
predict where future r eads may occur. If it detects a pattern, the
data that seems most likely to be read next will be preloaded
into the controller’s cache memory. Since reading data from
memory on the controller is much faster than reading it fr om
the drives, this can have a significant impact on performance.

This setting defaults to Enabled.

Step 2 of 3 in the Advanced area of the Create Array wizard offers
the following additional options:

■ Limit Array Capacity—This option allows you to choose the

capacity of the array you are creating. The default is to make the
array the largest possible size with the drives selected. To create
multiple arrays on a single set of drives you must use this
option to limit the size of, at a minimum, the first array.

For example, if you have two 18 GB drives, and you wish to use
them to create two 9 GB RAID-1s, you would use this option to
restrict the size of the first array you create.

Note: A RAID-1 uses two drives to create a mirror; that is

all data written to a RAID-1 is written to both drives
limiting the capacity of the array to the capacity of the
smaller drives.

■ Stripe Size—For a RAID-0, 5, 10 or 50 where data is striped

across multiple drives, stripe size determines how much data is
written on each drive for a given stripe.

Note: The default stripe size has been chosen to maximize

performance for most typical applications. Changing the
stripe size is likely to adversely affect performance.

3-14

Adaptec Storage Manager-Browser Edition

For arrays which need to be initialized such as RAID-1 and
RAID-5, advanced options allow you to select which method is
used to initialize the array and set the priority of the initialization
task.

Step 3 in the Advanced area of the Create Array wizard offers the
following initialization options:

■ Build—For a RAID-1, the data from the primary or master

drive is copied to the secondary or slave drive. For a RAID-5,
correct parity is generated for the entire array.

The advantages of building an array are that the array is
immediately available for use, and that when the build is
complete, the array operates at maximum performance. The
disadvantages are that building takes some time, for a large
array possibly many hours, and performance is impacted until
the build completes.

■ Clear—In this case, the contents of all the drives are cleared.

The advantages of clearing an array are that the process is much
faster than building and when completed, the array operates at
maximum performance. The disadvantage is that the array is
not accessible until the clear completes.

■ Quick—In this case the array is immediately available. The

advantage of quick initialization is that the array is immediately
available with no on-going build. The disadvantage is that the
write performance of a RAID-5 or RAID-50 initialized in this
way is impacted until a Verify with fix Task is run on the array.

■ Initialization Priority—This drop-down list allows you to

adjust the priority of the initialization task. The default setting
is high, and initialization will complete as fast as possible. The
other options are medium and low. Depending on what other
tasks are running on the controller, selecting either of these
options may cause the initialization to take significantly longer.

Creating and Deleting Hot Spares

Creating Hot Spares

To create a hot spare:

1 Click on the button on the Physical Devices view.
2 In the Phys ical Devices view, select the drive(s) you want to

make hot spares.

Note: You cannot select a drive that is already used in an

array as a hot spare.

3 The advanced option for the Hot Spare button describes how to

dedicate a hot spare to protect a single array.
If you wish to dedicate a hot spare to protect a si ngle array,

select the array you want the hot spare to protect. If you do not
select an array, the hot spare(s) will be global, that is they will
protect all the arrays on the controller that they are large
enough to protect.

4 Click Finish. Deleting Hot Spares

To delete a hot spare:

1 Click the Hot Spare button on the Physical Devices view.
2 In the Physical Devices view select the hot spare(s) you wish to

delete.

3 Click Finish.

3-16

Adaptec Storage Manager-Browser Edition

Deleting Arrays

To delete an array:

1 Click the Delete button on the Logical Devices view.
2 In the Logical Devices view select the array(s) you wish to

delete.

3 Click Finish.

Deleting an array destroys all the data on the array. To help
prevent you from deleting the wrong array, a dialog will pop
up listing the array(s) that you selected in step 2.

4 Check that you selected the correct array(s) before clicking Yes.

Modifying Arrays

Modify allows you to make the following changes to existing
arrays:

■ Migrate an array from one RAID level to another

■ Expand the capacity of an array

■ Change the stripe size

Some operating systems, for example Windows 2000 and W indows
XP, support Online Capacity Expansion (OCE). That is, on
completion of an array expansion, the additional capacity can be
used without rebooting the system. Refer to your operating sys tem
documentation for instructions on using the additional capacity.

Supported RAID level migrations are given in Table 3-1.

Table 3-1 Supported RAID Level Migrations

Current Array T ype New Array T ype

RAID-0 RAID-5 or 10
RAID-1 RAID-0 or 5 or 10
RAID-5 RAID-0 or 10
RAID-10 RAID-0 or 5
RAID-50 RAID-0 or 5 or 10

3-17

Adaptec SCSI RAID 2120S/2200S Software User’s Guide

The following rules apply to migration:

1 The capacity of the new array must match or exceed the

capacity of the current array.

2 If the capacity and/or RAID type of the new array requires

greater total drive capacity than the current array, the
additional capacity must be on drives that are not already used
in the current array.

To modify an array:

1 Click Modify.
2 Select the array that you wish to modify.
3 Select the RAID level that you want to migrate the array to, or if

you want to expand the capacity of the existing array, select the
current RAID level.

Optionally, click Advanced to select the stripe size you want the
new array to use, or that you want to change the existing array
to.

4 If necessary, select the additional drive(s) required for capacity

expansion, or necessary to support the new RAID level.
Optionally, click Advanced to adjust the priority for the task.

5 Click Finish.

About Adaptec Storage Manager Notifier Service

Adaptec Storage Manager - Browser Edition includes a notifier
service that enables controller events to be added to the system
event log. This service can notify users, through e-mail, of
controller events.

When you install Adaptec Storage Manager on a syst em equipped
with an Adaptec Advanced RAID controller, the notifier service is
installed and configured to log all events to the system ev ent log.
The default installation has email event notification disabled.

Notifier Service Event Levels

Adaptec Advanced RAID controllers support three event levels:

■ Critical

■ Warning

■ Informational

The level(s) of events entered in the system log and received by
each user is configured independently.

3-29

Adaptec SCSI RAID 2120S/2200S Software User’s Guide

The notifier utility is named slightly differently depending on
which operating system you are using. For all vers ions of Micr osoft
Windows the utility is named notify.exe, while for Novell
NetWare it is named notify.nlm, and for all Linux and Unix
variants it is named anotifyd.

All versions of the utility support the -c switch. This switch runs
the notifier in a configuration mode that leads you through the
steps necessary to configure the system event log and e-mail
notification.

In addition to -c, the Microsoft Windows version of the notifier
supports the switches in Table 3-2.

Table 3-2 Switches

-c Starts the notifier in configuration mode.

-? Lists the switches supported by the notifier.

-i Install - installs the notifier service. The notifier is

installed by default. If the service has been
uninstalled for any reason, this switch will install the
service and set it to start automatically from the next
boot.

-u Uninstall - removes the notifier service.

-v Version - lists the version number of the notifier

service.

-s Start - starts the notifier service.

Enabling and Configuring the Notifier Service

Before you begin to configure e-mail notification you need to have
the following information available:

■ The SMTP mail server host name or IP address.

■ The port that SMTP mail server is configured to use. The default

value of 25 was chosen because it is the default for most SMTP
mail server packages. If you are unsure ask your e-mail
administrator.

■ The SMTP e-mail address to which all returned e-mail should

be forwarded. SMTP e-mail addresses take the form
[e-mail].

■ The SMTP e-mail address of all users that need to receive event

notifications.

Before you configure the notifier be sure the notifier service and
ARCPD are stopped.

Controlling ARCPD for Windows 2000

To stop the ARCPD for Windows 2000, right click My Computer >

Introducing the Command Line Interface

To configure and manage components running on the controller,
Adaptec provides an easy-to-use graphical user interface (GUI)
called Adaptec Storage Manager as well as a command line
interface (CLI).

The CLI provides an alternative to Adaptec Storage Manager.
Through the CLI, you can perform most of the storage
management tasks that you can perform with Adaptec Storage
Manager and, in addition, some tasks not available in the GUI. To
automate testing or array creation in a production environment,
the CLI enables you to use CLI commands in Windows command
scripts and UNIX/Linux shell scripts.

This chapter describes briefly some of the commands available in
the CLI. For a full description of all the CLI commands see the
Adaptec SCSI RAID Software Reference Guide.

Accessing the Command Line Interface

You can execute the command line interface (CLI):

■ From the Windows XP, Windows 2000 or Windows NT Start

button

Note: The following procedure assumes that you accepted

the default location for the software during installation.

To access the CLI from the Windows XP(basic disk only),
Windows 2000(basic disk only) or Windows NT Start button:

1 Click the Start button and move the mouse cursor to

Programs. Click on Programs.

2 Move the mouse cursor to SMBE. The Adaptec program

group will display.

3 Move the mouse cursor to the CLI icon. Click on CLI.

■ From the NetWare server console

To access the CLI from the NetWare server console, type
aaccli at the prompt. When the system displays the CLI>
prompt, which indicates that you can now use CLI commands.

4-2

Using the Command Line Interface

■ From the UNIX/Linux prompt

To access the CLI from the UNIX/Linux prompt, display a
window and type aaccli in any directory. When the system
displays the CLI> pr ompt, you can use CLI commands. For the
commands to work in any directory, the path in the startup file
(.login or .cshrc) must include the directory where the
software is installed. See your UNIX/Linux documentation for
information on setting up directory paths in the .login and
.cshrc files.

Terminology

For a complete discussion of terminology, see the Glossary in this
guide. Table 4-1 lists and defines some terms used in this chapter
and is presented here for your ease-of-use:

Table 4-1 Terminology Chart

Term Preferred Term Definition

container array A logical disk created from

available space and made up of one
or more segments on one or more
physical disks.

chunk stripe Contiguous set of data written to

one segment before the controller
moves to the next segment.

freespace available space Space on an initialized disk that is

not in use.

partition segment Contiguous area of a physical drive

that makes up some or all of an
array.

failover disk hot spare Drive available to replace a failed

component in an array.

Before any command can be sent to a specific controller that
controller must first be opened. Only one controller may be open at
any time.

To open controller AAC0 use the following command.

CLI> open AAC0

When you have finished with the controller close it with the
following command.

AAC0> close

Creating Single-Level Arrays

This section explains how to create and work with single-level
arrays. The RAID software supports four types of single-level
containers:

■ Volume

■ RAID 0

■ RAID 1

■ RAID 5

4-4

Using the Command Line Interface

Before you can work with arrays, you must have previously
opened the controller. In addition, you must have initialized your
disk(s) to prepare for array operations.

The minimum size of an array is 10 MB.
Before creating any array, use the disk show space command

to display information about your disks. In the following example,
the Usage column indicates Free for each disk, which means that
the space on each disk consists of available space.

AAC0> disk show space

Executing: disk show space
Scsi C:ID:L Usage Size

----------- ---------- ------------­2:01:0 Free 64.0KB:8.47GB
2:02:0 Free 64.0KB:8.47GB
2:03:0 Free 64.0KB:8.47GB
2:04:0 Free 64.0KB:8.47GB

After creating an array, use the container list command to
display information about the array. In the following example, the

Num Label column indicates the array ID 0 and the array label
Venus. The Type column indicates a Volume set. The Total Size
column indicates that the array is 100 MB.

AAC0> container list

Executing: container list

Creating a Volume Set

To create a volume set, use the container create volume
command. In the following example, the volume set 0 is created on
SCSI device (2,01,0) from 100MB (megabytes) of available space.
The array’s raw cache is enabled, and the label Venus is specified.

AAC0> container create volume /cache=TRUE /label=Venus
((2,01,0), 100M)

Executing: container create volume /cache=TRUE /
label=Venus ((CHANNEL=2,ID=1,LUN=0),104,857,600)

container 0 created

Adaptec SCSI RAID 2120S/2200S Software User’s Guide

Creating a RAID 0

When creating a RAID 0, you need to determine the stripe size that
is most suitable for your environment. The stripe size attribute
indicates the number of bytes in a stripe, the amount of data
written to a segment before the I/O data stream switches to the
next segment in the stripe. The stripe size can be 16 KB, 32 KB, or
64 KB. The default stripe size is 32 KB. Note that you can use the
container reconfigure command at a later time to change the
stripe size.

To create a RAID 0, use the container create stripe
command. In the following example, the stripe set 0 is created on
SCSI device (2,01,0) from 100 MB of available space. The array’s
raw cache is enabled, and the label Mars is specified.

AAC0> container create stripe /cache=TRUE /label=Mars
((2,01,0), 100M)

Executing: container create stripe /cache=TRUE /
label="Mars" ((CHANNEL=2,ID=1,LUN=0),104,857,600 )

container 0 created

Creating a RAID 1

To create a RAID 1, use the container create new_mirror
command. In the following example, a RAID 1 is created on SCSI
devices (2,2,0), and (2,3,0) using 100 M of available space from each
SCSI device.

AAC0> container create new_mirror ((2,2,0), 100M)
(2,3,0)

Executing: container create new_mirror
((CHANNEL=2,ID=2,LUN=0),104,857,600 )
(CHANNEL=2,ID=3,LUN=0)

4-6

Using the Command Line Interface

Creating a RAID 5

When creating a RAID 5, you need to determine the stripe size that
is most suitable for your environment. See Creating a RAID 0 for
more information about determining the appropriate stripe size for
your environment.

To recreate the data of a failed disk in a RAID 5, you use a form of
redundancy called parity. When you set up parity, you initialize
the parity stripes by using a scrubbing switch (/scrub=TRUE).
Parity is set up in the background, and the disks are available
immediately.

The /scrub switch is not available in UNIX/Linux. For UNIX/
Linux, the RAID 5 is always created by building.

To create a RAID 5, use the container create raid5
command. In the following example, a RAID 5 is created on SCSI
devices (2,1,0), (2,2,0), and (2,3,0) using 100 M of available space
from each SCSI device. The /stripe_size switch specifies that each
stripe is 64 K in size.

AAC0> container create raid5 /stripe_size=64K ((2,1,0),
100M) (2,2,0) (2,3,0)

Executing: container create raid5 /stripe_size=65,536
((CHANNEL=2,ID=1,LUN=0),104,857,600)
(CHANNEL=2,ID=2,LUN=0) (CHANNEL=2,ID=3,LUN=0)

Deleting Arrays

To delete an array, use the container delete command. In the
following example, array 0 is deleted.

AAC0> container delete 0

Executing: container delete 0

After running the container delete command, use the
container list command to verify that the array was deleted.

In the following example, no arrays are found on the controller.

AAC0> container list

Executing: container list
No containers found.

Enabling Spares

A spare disk (also called a “hot spare”) is a disk that you configure
to recover data from a failed segment/disk in a redundant array.
To assign one or more spare disks for a single array, use the
container set failover command. To assign one or more
spare disks for all arrays, use the container set
global_failover command. The main characteristic of these
commands is that you must “manually” assign the spare disk to
one or more arrays. In fact, you might consider the previously
described spare mechanism as “manually set spare.”

Note: RAID 1, 5 10 and 50 use the spare assignment if a disk

fails. (RAID 1, 5, 10 and 50 are often referred to as redundant
arrays).

Automatic rebuild on replacement allows you to replace a failed
disk with a replacement disk. The controller automatically assigns
the disk you insert as a hotspare without your having to first assign
it manually using the container set failover or
container set global_failover command.

See the Adaptec SCSI RAID Software Reference Guide for more
information on the container set failover and container
set global_failover commands.

Caution: The controller deletes any data on the replacement

disk when automatic rebuild on replacement is enabled and
you remove the failed disk and insert the replacement disk in
the failed disk’s slot.

Note: The automatic spare feature works only with disks that

reside in an SAF-TE or SES enabled enclosure.

Through the CLI, you can:

■ Display a controller’s automatic rebuild on replacement status

■ Enable automatic rebuild on replacement

4-8

Using the Command Line Interface

To display a controller’s automatic rebuild on replacement status,
use the controller show automatic_failover command.
In the following example, rebuild on replacement is indicated as
DISABLED.

AAC0> controller show automatic_failover

Executing: controller show automatic_failover
Automatic failover DISABLED

To enable automatic spare, use the controller set
automatic_failover command with the /failover switch, as in

the following example:

AAC0> controller set automatic_failover

/failover_enabled=TRUE

Executing: controller set automatic_failover
/failover_enabled=TRUE

After running the controller set automatic_failover
command, use the controller show automatic_failover
command to verify that automatic rebuild on replacement has been
enabled. If necessary, you can now replace a failed disk with a
replacement disk.
