RAIDWatch User’s Manual
User’s Manual Overview
Congratulations on your decision to use Infortrend’s RAIDWatch
management software program. This management program allows you to
control and monitor disk array subsystems from a local host, a remote
station connected through a local area network (LAN), or the Internet.
This manual discusses how to install and use RAIDWatch to manage disk
array systems incorporating Infortrend’s Fibre-to-Fibre, Fibre-to-SATA,
SCSI-to-SATA, iSCSI-to-SATA, and SCSI-to-SCSI subsystems, or the
EonRAID 2510FS series controllers. Please note that RAIDWatch does not
support drive enclosure displays manufactured by other vendors.
In addition to RAIDWatch, you can also use the on-board COM port or
LCD panel to manage the EonStor subsystems or systems that incorporate
the EonRAID disk array controllers. For more information about these
programs, see the documentation that came with your hardware.

RAIDWatch User’s Manual
Usage Conventions
Throughout this document, the following terminology usage rules apply:
•
“Controller” always refers to Infotrend RAID array controllers.
•
“Subsystem” refers to Infortrend EonStor 8-, 12-, or 16-bay RAID
array subsystems.
•
“RAIDWatch” refers to the entire program and all of its modules.
•
“RAIDWatch Manager” refers only to the management interface,
not to any other parts of the software.
•
“Root Agent” is an independent agent of the software, which
permits one management station to monitor and report the
operating status of multiple RAID systems. The Root Agent gets
information from and sends commands to one or multiple RAID
arrays.
•
“RAID Agent” is the part of the software, which allows the RAID
controller/subsystem to talk to the RAIDWatch Manager or Root
Agent. A RAID Agent communicates with the RAID array via
SCSI bus, iSCSI or Fibre channels (using the In-band protocols), or
via an Ethernet port. RAID Agents are the intermediaries between
RAID systems and the RAIDWatch program.
•
“Configuration Client” refers to the software utility that allows an
administrator to be notified of system events at any of the RAID
systems being managed. The Configuration Client also enables
centralized management of multiple arrays using a single
workstation.
Important information that users should be aware of is indicated with
the following icons:
NOTE:
These messages inform the reader of essential but non-critical
information. These messages should be read carefully as any directions
or instructions contained therein can help you avoid making mistakes.
CAUTION!
Cautionary messages should also be heeded to help you reduce the
chance of losing data or damaging the system.
xiii
RAIDWatch User’s Manual
IMPORTANT!
The Important messages emphasis on using RAIDWatch management
software.

Revision History
May 18, 2005
This manual was revised for RAIDWatch revision 2.2. RAIDWatch is now a
registered trademark of Infortrend Technology, Inc. Chapter 6 was moved
to Chapter 2 to introduce RAID and RAIDWatch considerations to user
before installation.
The program supports more operation environments that are listed in
Chapter 1. Chapter 1 also describe the new features such as the multilanguage support include English, Deutsch and Japanese for the software
GUI and online help. The auto complete feature is added. This feature saves
time when user is trying to connect a RAID system by typing in an IP
address that was previously connected in the connection window.
The typical program installation opinion is newly provided while installing
RAIDWatch. The option is fully described in Chapter 3. RAIDWatch 2.2
comes with enhanced install shield program. The graphics used to explain
the RAIDWatch installation are modified. The system requirements and
platform requirements are also being updated in this chapter.
A Quick Installation icon under Configuration category is included in
Chapter 5.
The new Chapter 6 (previously Chapter 5) was rearranged to fit the current
software version. The auto complete feature is included in the connection
window. The new agent list window combined with auto discovery function
is described in the chapter. A new function called Quick Installation is being
added in the configuration category. The explanation of using Window
commands is being added.
In Chapter 11, the event log list/configuration list functions are newly
described. Users are able to use those functions to monitor and report the
system status.
The content of Chapter 12 is enhanced with more information.
December 20, 2004
Two new functions are being added. By using RAIDWatch revision 2.1.c,
the configuration client supports the auto discovery of iSCSI models to auto
detect the available agents. The new function is fully described in Section
3.5. A restore factory defaults function is newly provided in the RAIDWatch
main program. The function description can be found in Section 7.4.
November 15, 2004
Revised for RAIDWatch revision 2.1.b. This is an initial RAIDWatch
version to support iSCSI subsystems. The cover of the manual and the
xv
RAIDWatch User’s Manual
header/footer through out the manual were modified to match the hardware
manual. Graphics for note, caution, important, and warning messages were
added. In Chapter 3, some figures for notification settings were added to
make the description more clear. The Generate Dummy Event function is
added to the Configuration Client management utility. In the same chapter,
GSM modem information for SMS message event notification function was
also added. A new Task Schedule icon was added in Chapter 4. In Chapter
5, Section 5.9: Multi-array Management was added. SCSI channel and
compatible cables were explained clearer in Chapter 8.
August 10, 2004
Revised for RAIDWatch revision 2.1. Added descriptions for new
configuration options including the NPC utility for the Applet mode
installation. Added Chapter 13: NPC Utility.
April 20, 2004
Completely revised for RAIDWatch 2.0, but still kept the manual structure.
Although software revision 2.0 has a brand new look and feel and a different
configuration access, the available configuration options are basically the
same. One chapter, Event Monitor, was removed because the functionality
was combined with GUI screen interface. The chapter for NPC functionality
was also removed because the event notifications were integrated with the
Configuration Client utility.
October 15, 2003
Chapter 13 and Chapter 14 were merged into a single chapter, Chapter 13:
Panel View. This chapter generally describes the panel view and removes
the redundant descriptions that were previously in both Chapter 13 and
Chapter 14. Part 4 of the previous edition was also removed and Chapter 13
has been included in Part 3 of the Manual.
September 29, 2003
Figure 1-1 in Chapter 1 was changed to show a rackmount enclosure.
Section 3-1 in Chapter 3 was divided into two sections: “Using Windows –
RAIDWatch Installed as In-Band” and “Using Web Browser – RAIDWatch
Installed as Applet.” Section 3.5, “Rebooting the Controller,” was also
added. Modifications to Table 14-1 were also made.
August 28, 2003
This manual was completely revised from previous editions. Previous
editions came with six chapters and six appendices; the current revision has
fourteen chapters divided into four parts and five appendices. The main
changes to this edition are given below.

RAIDWatch User’s Manual
Chapter 1 remained largely unchanged with only minor editorial corrections
that do not directly affect the content.
Chapter 2 was separated into two chapters. In the previous revision,
Chapter 2, Installation, described system and platform requirements,
installation, and different configuration options. This chapter was separated
into Chapter 2 Installation, which describes the new RAIDWatch installer,
and Chapter 3 Configuration Options in the new revision.
Chapter 3 in the old revision on Basic Operations became Chapter 4 in the
new revision. More detailed instructions on how to use RAIDWatch were
added and new screen captures included.
Chapter 4 in the old revision on Array Management has been separated into
six new chapters in the new revision. Five of the new chapters, Chapter 5 –
Chapter 9, make up Part 2 of this revision of the user’s manual and the
sections in Chapter 4 of the previous edition on S.E.S. management and IIC,
SAF-TE and Fault bus management were moved into Chapter 10 of this
revision. All these chapters have enhanced descriptions on how to manage
an array, and a series of more indicative screen captures were added.
Chapter 5 Notification Processing Center and Chapter 6 Event Monitor in
the older revisions of the user’s manual became Chapter 11 and Chapter 12,
respectively, in the new revision. The content of these chapters remained
largely unaltered with only a few minor editorial adjustments.
Appendix A in the previous revision was moved to Chapter 13 in the
current revision and is followed by a completely new chapter, Chapter 14
on EonStor storage subsystem panel view customizations.
Extracting Appendix A from the appendices reduced the number of
appendices from six to five and the names of each appendix changed to a
higher letter, e.g., Appendix B in the last revision is now Appendix A,
Appendix C is now Appendix B, etc. The content of these appendices
remained the same.

RAIDWatch Overview
1.1.1
Product Description
Infortrend’s innovated RAID manager, RAIDWatch, is a Java-based
program specifically designed for use in managing Infortrend’s RAID
subsystems.
RAIDWatch provides a user-friendly interface that graphically represents
disk array elements and simplifies the normally complicated process of
array configuration. RAIDWatch also provides real-time reporting on the
status of the entire array, thus making the task of monitoring disk arrays
virtually effortless. The functionality provided in the Event Monitor submodule in the previous RAIDWatch versions is now integrated into the
main management screen and the Configuration Client.
RAIDWatch complements the on-board console interface found on
Infortrend’s RAID controllers and a line of host-based, text mode RAID
Managers that provide the same functionality, but with greater ease of use.
The following sections describe the outstanding features of RAIDWatch and
introduce its conceptual framework.

Featured Highlights
1.2.1
Graphical User Interface (GUI)
RAIDWatch manager is designed for ease-of-use. It uses symbolic icons to
represent configuration levels, physical and logical drives, and logical
volumes on the screen, and to identify the current configuration of a disk
array system. Pull-down, right-click, and pop-up menus are used with all
command options.
You need only point-and-click a mouse button to select an icon or
command. The program also displays the current status of various disk
drives or enclosure components by changing the color of their respective
LED icons.
With an easy-to-use interface, complicated disk array operations such as
logical drive and logical volume creation, drive partitioning, and drive
partition mapping to host channels/LUNs can be completed with just a few
mouse clicks.
1.2.2
Enclosure View
Figure 1-1: Enclosure View Window
The enclosure window shown in Figure 1-1 provides real-time reporting of
the status of enclosure components, including components that can be
accessed through the front or the rear side of an enclosure. When a drive
fails, the system highlights the corresponding LED icon of the failed drive
Featured Highlights
1-3
RAIDWatch User’s Manual
by changing its display color. When you remove a drive, its icon is removed
from the enclosure window. This feature is particularly useful in cases when
a drive fails, and you need to identify its exact location for subsequent
replacement.
The enclosure window also appears in other configuration windows showing
the logical relationship between the member drives of a logical
configuration. Drives belonging to the same logical drive will be displayed
in the same color. This allows you to easily identify members of different
configurations. To see a cascaded enclosure, single click on the “JBOD”
page on top of the enclosure graphic.
1.2.3
Powerful Event Notification Function
Figure 1-2: Event Notification Function
RAIDWatch can notify system administrators of event occurrences and
status changes in the RAID system. Event Notification is managed by a
RAIDWatch’s sub-module, Configuration Client that is installed onto a
management station and runs independently from the main manager
program. Notifications can be sent via the Internet as email messages, via a
local network as a broadcast message, SNMP traps, ICQ or MSN
messenger, SMS short message, or via fax/modem as fax messages without
location constrain. To setup the event notification options, please refer to
Chapter 4 in this manual.
1.2.4
Java-based Remote Management
RAIDWatch supports local or remote management of Infortrend EonStor
subsystems over a LAN/WAN or the Internet using the TCP/IP protocol.
RAIDWatch can be highly flexible to access to a RAID subsystem. When
“Advanced” installation is chosen during the installation process, three (3)
installation schemes are available for you to select using the install shield
program. (See Figure 1-3) Below sections are the explanations of the three
options.
1-4
Featured Highlights
Chapter 1: Introduction
NOTE:
The default setting of RAIDWatch installation is using basic installation.
Basic installation is the same as Mode 1, Centralized Management, in
Advanced installation.
Figure 1-3: Installation Options
1.2.4.1 Mode One: Centralized Management
For centralized or one-to-many configurations using either the Ethernet or
in-band host connection to RAID subsystems. The root agent and submodules, including the Configuration Client and RAIDWatch Gate, are
included. Necessary RAID agents are installed onto the management
computer.
1.2.4.2 Mode Two: Stand-alone (on Host)
For configurations depending on the existing SCSI, iSCSI, or Fibre host
connection for RAIDWatch-to-RAID communications. Servers in DAS
(Direct Attached Storage) environments, SCSI host models for example,
require RAID agents for RAIDWatch commands to pass through and
communicate with RAID arrays. RAID agents are installed onto the servers
that are directly attached with a RAID subsystem.
1.2.4.3 Mode Three: Stand-alone (on Subsystems)
For remote and server-transparent management using an Ethernet
connection to EonStor subsystems or EonRAID controllers. The manager
program is installed on the RAID subsystem itself. The RAID subsystem
then uses a segregated disk space, called the “reserved space,” to store the
program files. The array is accessed by invoking a Java Applet on a web
browser that runs anywhere in the network.
Featured Highlights
1-5
RAIDWatch User’s Manual
NOTE:
RAID agents are embedded in the RAID subsystem firmware. When
subsystems are installed in Mode 2 or Mode 3, the management station
running in Mode 1 can manage the RAIDWatch components. This way,
multiple and/or distant arrays can be managed by a single management
station.
1.2.4.4 Access Requirements
Three (3) installation schemes for different access requirements are
discussed below.
NOTE:
The discussions below do not include all possibilities. RAIDWatch
supports various configurations and the combinations of machines
running components installed in any of the three different modes.
1.
A RAID Server Chosen as the Centralized Management Station:
Applied in heterogeneous environments where multiple arrays are
serving different hosts/applications and scattered in distant locations.
Access management over the network is achieved through data
exchanges between a local or remote RAIDWatch Manager station
(can be a RAID server or not) and RAID agents that are installed on
the RAID servers or RAID subsystems themselves. The management
center and the RAIDWatch station can be two different machines.
A Root agent is installed on a computer chosen to be the
management center. Figure 1-4 shows a typical connection and
Table 1-1 shows the modules installed and the installation mode
required:

Multi-Language Support
RAIDWatch is a useful RAID management tool that is being used
worldwide. The software is currently available in three languages: English,
Deutsch and Japanese. Support for other languages is under development.
The language display is easily changed using the language selection on the
program menu bar. As soon as a language is selected, the user interface,
wizards, and online help display the chosen language.
1.2.6
Password Protection
RAIDWatch Manager comes with password protection to prevent
unauthorized users from modifying the configuration of the RAID system.
With the password security feature, you have control over array settings
knowing that the currently managed disk array is safe from unauthorized
modifications because the correct password must be entered for each access
level.
The RAIDWatch management screen has a navigation tree panel that
provides access to functional windows under three major categories:
•
Information: An Information login can only access the first level,
Information.
•
Maintenance: A Maintenance (user) login can access the second
level, the Maintenance tasks.
•
Configuration: The Configuration (administrator) login has
access rights to all three levels, Configuration, Maintenance, and
Information.
NOTE:
The default password for Information categories is 1234.
Passwords for access levels can be set in the Configuration category
under the “Configuration Parameters” “Password” settings. Please
refer to Section 7.5.

Conceptual Foundation
In order for RAIDWatch to function properly, different software modules
must be correctly installed on different servers and stations in a given LAN
or WAN. If you follow the default installation during the installation
process, RAIDWatch will be installed as a centralized management tool into
your system.
1.3.1
Centralized Management (Agent-based)
Installation
1.
RAIDWatch communicates with a RAID subsystem either using the
firmware-embedded RAID agents or agents manually installed onto
a RAID-attached server. Assuming that a given network has multiple
RAID systems, RAIDWatch can communicate with RAID arrays
through the RAID agents installed on the servers or on the RAID
subsystems.
2.
A server is chosen as the main management server. When
RAIDWatch is installed onto this server using the first installation
scheme, two important modules are included, Configuration Client
and Root Agent. The Configuration Client enables automatic
notifications of system events, and the Root Agent communicates
with multiple RAID subsystems that are not directly attached to this
server.
3.
The main management server will also need Java Run-time
Environment (JRE) installed if a system administrator needs to
configure the arrays from it.
4.
Table 1-4 on page 1-11 provides a guide to what modules need to be
installed on which servers.
NOTE:
The items in the lower section of Table 1-4, JRE, web browser and/or
web server are not included with RAIDWatch management program;
therefore, they must be installed or modified by system users.

Stand-alone (on Host) Installation
Main features of the RAID-based installation method are listed
below:
1.3.3
•
RAIDWatch main programs and the RAID agents used to
communicate with a RAID subsystem over in-band
connection are installed.
•
RAIDWatch runs on the RAID-attached server as a Java
program.
Stand-alone (on Subsystem) Installation
Main features of the RAID-based installation method are listed
below:
•
Conceptual Foundation
RAIDWatch revisions 2.0 and above support installation
to array hard drives. A portion of the drive capacity
(256MB of disk space) is segregated and formatted on
each hard drive. This segregated portion is called a
“reserved space.” Once installation begins, RAIDWatch’s
main programs are automatically distributed to the
reserved space.
1-11
RAIDWatch User’s Manual
NOTE:
The RAIDWatch 2.0 or above installation only executed when hard drive
is formatted or at least one logical drive exists. Use LCD panel or RS232 terminal program to create a logical drive when you are using new
hard drive before installing RAIDWatch 2.0 or above version.
1-12
•
There is no need to install the RAIDWatch program to
your management computer.
•
If the arrays are managed by dual-redundant controllers, in
the event of single controller failure, the manager interface
can “failover” to a counterpart controller. Operators’
access to the system will not be interrupted.
•
The RAID subsystem can be accessed from a remote
station running a web browser. RAIDWatch now runs in
Java Applet mode. Applet is executed when the
connection is established between a remote browser and
the RAID subsystem. Web browsers, which are often
equipped with Java virtual machines, can interpret applets
from web servers.
•
The controller firmware has an embedded HTTP server.
Once properly configured, the controller/subsystem’s
Ethernet port behaves like an HTTP server.

RAIDWatch Considerations
Before you begin installing RAIDWatch, the following items should be
considered:
♦ Background Information – Section 2.1 on Page 2-2
♦ Definition of Terms – Section 2.2 on Page 2-2
♦ Operating with Spare Drives – Section 2.3 on Page 2-3
♦ Operating without Spare Drives – Section 2.4 on Page 2-4
♦ Before You Start – Section 2.5 on Page 2-4
Background Information
2-1
RAIDWatch User’s Manual
2.1 Background Information
Redundant Arrays of Independent Disks (RAID) is a storage technology
used to improve the processing capability of storage systems. This
technology is designed to provide reliability (i.e., “fault tolerance”) in
disk array systems and to take advantage of the performance gains
multiple disks can offer.
RAID comes with a redundancy feature that ensures fault-tolerant,
uninterrupted disk storage operations. In the event of a disk failure, disk
access will still continue normally with the failure transparent to the host
system.
RAID has several levels and multi-level configurations including RAID
10, 30, and 50. RAID levels 1, 3 and 5 are the most commonly used
levels, while RAID levels 2 and 4 are less popular. Appendix C, RAID
Levels, gives information about these levels and the benefits of each.
Infortrend disk array controllers support hot-swapping so that a failed
drive can be replaced while the disk array system continues to function.
Spares can also be assigned so that, as soon as a drive fails, the spare is
automatically configured into the array and reconstruction will
commence.
2.2 Definition of Terms
This section describes some of the disk array terms used in this
documentation.
♦ Physical drives. These are the actual drives installed into the
enclosure drive slots. These drives are displayed in Enclosure View
and the Front View of different configuration windows.
♦ Spare drives. These are physical drives that serve as backups.
When a drive fails, the spare automatically joins the array and data
reconstruction commences immediately. Dedicated and Global
Spares are shown in different colors. A Dedicated Spare appears in
the same color as other members of the logical drive it belongs to.
A Global Spare uses the default color (black). Both Dedicated and
Global Spares have an orange cross superimposed on them.
♦ Replacement drives. These are physical drives that are manually
configured into the array to replace failed drives. In the absence of
spare drives, you will need to use replacement drives to replace
defective drives before rebuilding. If a spare drive has been used to
2-2
Background Information
Chapter 2: RAIDWatch Considerations
rebuild the array, you will also need to replace the failed drive
manually to create another spare in case another drive fails.
♦ Failed drives. These are physical drives that fail due to some type
of error. Failed drives appear with red LED marks on their
respective icons.
♦ Logical drives. Logical drives are the combinations of multiple
physical drives. Combining physical drives into logical drives gives
you a disk array with a certain RAID level. To view logical drives,
select “Existing Logical Drives” under the navigation menu tree.
♦ Logical volumes. Volumes are the combinations of several logical
drives. Combining logical drives into logical volumes gives you a
single logical unit with even larger capacity. Logical volumes or
their partitions are mapped to various host LUNs. To view logical
volumes, select “Existing Logical Volumes” under the navigation
menu tree.
2.3 Operating with Spare Drives
You can assign spare drives to a particular logical drive to serve as
backup drives. When a drive fails within the logical drive, one of the
spares will be automatically configured into the logical drive, and data
reconstruction onto it will immediately commence.
The following are guidelines for disk failure recovery when a spare drive
is available:
♦ If a spare drive exists in the same logical drive, the controller will
automatically mount the spare drive and start rebuilding data in the
background.
♦ Depending on system design, it may be possible to remove a
defective drive and replace it with a new drive without shutting
down the system (hot-swapping). All EonStor subsystems support
drive hot-swapping.
♦ The replacement drive must then be assigned as a new spare drive.
Operating with Spare Drives
2-3
RAIDWatch User’s Manual
2.4 Operating without Spare Drives
The following are guidelines for disk failure recovery when a spare drive
is not available:
♦ Depending on the design of the system, it may be possible to
remove a defective drive and replace it with a new drive without
shutting down the system (hot-swapping). All EonStor subsystems
support drive hot-swapping.
♦ If the replacement drive is installed on the same channel and ID
(the original drive slot where the faulty drive was), you can then
proceed with data rebuilding.
♦ If the replacement drive is installed on a different channel or ID
(different drive slot) or the periodic drive scan function has been
disabled, you need to scan in the new drive first, and then assign it
as a spare drive of the logical drive which had a drive failure. Data
rebuilding will have to be manually initiated.
IMPORTANT!
Although the RAID system provides uninterrupted disk access even after a
disk failure, do not leave a failed drive unattended. Without replacement,
the system will not survive a second physical drive failure on the same
logical drive. A defective drive must be promptly replaced and data
rebuilt.
CAUTION!
When performing hot-swapping, be sure to remove only the defective
drive. Removing the wrong drive will result in complete, unrecoverable
data loss. Use the Enclosure View window or Logical Drive Information
window to locate exactly which physical drive has failed.
2.5 Before You Start
RAIDWatch Manager comes with password protection that prevents
unauthorized modification of the disk array configuration. During each
attempt at modifying the system configuration, the configuration will
require the correct password before proceeding.
By default, the RAIDWatch Manager station comes with a password for
login as an Information viewer. For information on how to set a password
and other security features, see the Password section of Chapter 7,
Configuration Parameters.

Before You Start
Before starting the installation, read through the notes listed below:
♦ TCP/IP must be installed and running with a valid IP address assigned to
a server. The server can either be used as a centralized management
station, a remote client using a browser to access the array, or directly
attached with a RAID system using the in-band protocols.
♦ Your system display must be running in 256 colors or higher mode
otherwise some configuration items may not be visible.
♦ Be certain that your system meets the minimum hardware and software
requirements listed in Section 3.1 System Requirements.
♦ Check to confirm that the RAID disk arrays and controllers are installed
properly. For the installation procedure, see the documentation that came
with the controller/subsystems.
♦ Follow the directions provided in the Section 3.3 Platform
Requirements, and prepare for installation and operation under different
OS environments.
3.4.2
Installing RAIDWatch
Follow these steps to install RAIDWatch on your server(s) and RAID
subsystems:
Step 1. Insert the Infortrend product CD or RAIDWatch installation CD into
your CD-ROM drive.
Step 2. If you are currently running other applications, close them before
proceeding with the setup process. This will minimize the possibility
of encountering system errors during setup.
Step 3. The RAIDWatch installer program is included in a CD-ROM that
came with your RAID controller or subsystem. An auto-run screen
provides a hot link to the installer program. (See Figure 3-1) Click
“Install RAIDWatch.”

♦
Centralized Management – Selecting this option allows you
to install the RAIDWatch software, a Root Agent, RAID
Agents, Configuration Client utility, and necessary drivers on
the computer chosen as a management center.
♦
Stand-alone (on Host) – Selecting this option will install the
In-band driver (RAID agents) for servers that are directly
attached to a RAID subsystem, and the RAIDWatch software
on the local computer.
♦
Stand-alone (on Subsystem) – This will install the software
onto the controller/subsystem itself. The EonStor subsystems
come with necessary RAID agents embedded in the firmware.
A RAID subsystem will use a small section of formatted disk
space (called the reserved space) to store software related
Software Setup
Chapter 3: Installation
files. Installed in this mode, RAIDWatch can be started by a
remote browser accessing the IP address assigned to the
subsystem’s Ethernet port.
If the Stand-alone (on Subsystem) installation was selected,
you will have to use a web browser to connect to the
RAIDWatch program. To do this, open a web browser and
enter the controller/subsystem IP address. The RAIDWatch
program can then be accessed and used to manage the storage
array.
IMPORTANT!
There is no need to configure the Peripheral Device setting if you are
trying to manage a RAID subsystem from a RAIDWatch station through
an Ethernet connection (to the EonStor subsystem’s Ethernet port). An
Ethernet connection to RAID uses TCP/IP as the communication
protocol.

3.6
In-band SCSI
3.6.1
Overview
To meet the needs of device monitoring and administration, more and more
external devices require communication with the host computers. Out-ofband connections such as RS-232C ports or an Ethernet port can be used to
achieve this goal.
An alternative way of communication is in-band SCSI, which transfers
configuration commands into supported SCSI commands and uses them to
communicate with RAID arrays over the existing SCSI or Fibre host
connections. The traditional way for controllers to communicate with the
host computer has been via software (such as RAIDWatch) using an
Ethernet connection. With in-band, integrators have more flexibility and may
use the existing host connection instead.
There are limitations on the use of in-band protocols however. In order for a
host to “see” the RAID controller/subsystem, at least one (1) logical drive
must exist and be mapped to a host ID/LUN. Otherwise, the RAID
controller/subsystem itself must be configured to appear as a peripheral
device to the host computers.
See the examples below for the procedures on configuring RAID
controller/subsystems into a peripheral device.
3.6.2
Related Configuration on Controller/Subsystem
The RAID controller or subsystem must make some adjustments as well as
the host computer's SNMP settings before the two can communicate using
SCSI commands. You can use the RS-232 terminal to change the RAID
controller settings.
Step 1. From the Main Menu, press the Up or Down buttons to select “View
and Edit Configuration Parameters.”
Step 2. Press Enter; and then use the Up or Down keys to select “Host-side
SCSI Parameters.” Then press Enter.
3-14
Program Updates
Chapter 3: Installation
The Peripheral Device Type Parameters submenu is also need to be
adjusted. Refer to the instructions below to set the proper settings for the inband protocol to work.
Step 1. First select the “Peripheral Device Type” submenu and then select
“Enclosure Services Devices <Type=0xd>.”
Figure 3-14: RS-232 Terminal Screen (I)
Step 2. Select “LUN Applicability - Undefined LUN-0’s Only” option.
Figure 3-15: RS-232 Terminal Screen (II)
Step 3. Leave other options as defaulted. In-band should work fine by
setting these two options. The adjustments necessary to use in-band
protocols have been completed.
NOTE:
Be sure to change the Peripheral Device Type to your preference after inband SCSI connection has been setup.

Starting RAIDWatch Agents
Chapter 6: Basic Operations
6.1 Starting RAIDWatch Agents
6.1.1
Under Windows 2000/2003 OSes
Once the RAIDWatch software is properly installed, the necessary software
agents start automatically under Windows operation environment each time
the host computer is started or reset, e.g., RAID Agents and Root Agents.
However, the GUI part of RAIDWatch and the Configuration Client utility
need to be manually started.
Since the majority of RAID storage applications require non-stop operation,
the Configuration Client utility, which is used to monitor and report array
conditions, should be installed on a management server that runs 24-7
operation. For a higher level of fault tolerance in case of server failure, the
Configuration Client can be installed onto more than one server. As shown
below, when installing RAIDWatch using the Advance/Centralized
Management scheme, a pair of redundant servers can be specified in the
installation wizard prompt. The configuration is done by specifying IP
addresses for a Master Host and a Slave Host.
IMPORTANT!
RAIDWatch must be manually installed (Advanced Installation, and then
choose Mode 1 installation: Centralized Management) onto both the
Master and Slave hosts. The Configuration Client functionality on the
Slave host becomes active only when the Master host fails.
Figure 6-1: Installation Wizard Prompt: Redundancy Server
Before management can be performed on a particular disk array system, you
need to first establish a connection from your array to the network or a
connection between your array and the directly attached server. Once a
connection is established successfully, management can be started.
Starting RAIDWatch Agents
6-3
RAIDWatch User’s Manual
The following discusses how to connect to a disk array. Information on
disconnection is provided at the end of this section.
6.2 Starting RAIDWatch Manager
The management software interface, RAIDWatch Manager, needs to be
started by a network or RAID systems manager regardless of which OS is
being used.
Depending on your setup, you can start RAIDWatch Manager in various
ways.
For both local and remote management, and under various OSes, starting the
program is fairly simple. Please refer to the appropriate sub-sections below
for information.
6.2.1
Locally or via LAN under Windows 2000/
2003 Environments

wish only to manage one array, simply enter the IP address to
proceed.
As soon as you input the first number of an IP address, the
screen will show the previous entries that start with the same
number by auto complete feature. You are able to choose one
you are looking for from the list or type in a new IP address.
Starting RAIDWatch Manager
6-5
RAIDWatch User’s Manual
NOTE:
If you are not certain of a RAID array’s IP address, you may rely on
the Auto Discovery option in the Configuration Client to automatically
detect the available RAID arrays that are controlled by root agents. If
the Auto Discovery option is enabled, the available RAID array will be
shown automatically in the Agent List window that is described in
later this section. To use the Auto Discovery option, please refer to
Section 4.5: Auto Discovery.
Step 4.
You may select to enable the Secure Sockets Layer (SSL)
security option by a single mouse-click on its check box. SSL
works by using a private key to encrypt data when transmitting
private documents and obtain confidential information. SSL
creates a secure connection between a client and a server, over
which any amount of data can be sent securely.
Step 5.
Enter a user name by selecting from the pull-down menu.
Each user name represents an authorized access level. Enter a
password to proceed. Leave it blank if there is no preset
password. Click OK button to start the management session.
NOTE:
Refer to Section 6.3 for the details of the three authorized access
levels.
Agent List Window
Step 1. If you would like to see the available RAID systems that are
connected to the network or a specific root agent, you may click
the Show Root Agent List button on the bottom of the
RAIDWatch Connection window. The window displays the tree
tables of the available RAID systems that are detected by Auto
Discovery function. An example of an Agent List window is
shown in Figure 6-6.

Step 3.
You may refresh the Agent List window by select Refresh
under Root Agent command menu.
Step 4.
Click on the controller that you want to manage and select an
authorized access level. Enter any necessary password and the
program will lead you to its management session.
Step 5.
If you like the system to search the available RAID systems
again, pull down the System command menu and select Auto
Discovery. (See Figure 6-8) The new search result will be
showing in the Agent List Window.

6.3 Security: Authorized Access Levels
Password protection is implemented with the Connection wizard to prevent
unauthorized access to configured arrays. This protection, which is
implemented along with the security access levels, prompts a user for the
station password the first time he or she attempts to connect to a RAID
system.
By default, no password is required to access a RAID system using the first
two
protection
levels,
“Configuration”
(Administrator)
and
“Maintenance” (User). A default password is required for the Information
login.

6.4 Look and Feel
6.4.1
Look and Feel Overview
Because RAIDWatch Manager is a Java-based GUI program, it
accommodates the “look-and-feel” standards of various OSes. At present,
Windows interface appearance is supported.
RAIDWatch Manager will auto-detect and configure to match the OS where
it is currently running.
In the event of a compatibility problem or under an unknown OS or OS
versions, the program will default to the Java look and feel.
Just like other GUI-based applications, RAIDWatch Manager works entirely
with windows, buttons, and menus to facilitate various disk array
operations. These windows follow the standard Windows look-and-feel
specifications, so that manipulating elements and windows within any
RAIDWatch Manager window generally conforms to standard procedures.

Caching Parameters
♦ Write-Back Cache
Enabled, Host Writes are cached before being distributed to
hard drives. Improves write performance, but may require
battery backup support for data integrity in a case power outage
occurs.
Disabled, Cache Write-Through. Used primarily if no cache
battery backup is installed and there is increased likelihood of a
power failure.
♦ Optimization Policy
Optimization for Random I/O. More common setting. Use this
option for environments (e.g., database maintenance) with
smaller I/O transactions.
7-4
Controller
Chapter 7: Configuration Parameters
Optimization for Sequential I/O. Used for large I/O
environments such as video recording and editing. Particularly
useful where I/O read/write must be in sequential order.
♦ Sync. Period
This option allows you to select the desired interval for the partner
controllers in a dual-controller configuration to synchronize (mirrorcopy) their cached data. RAID controllers have defaults for this;
however, this option provides more choices with the sync. period.
Controller Parameters
♦ Controller Name
A manually entered nickname for the RAID controller. This name
can also be used to recognize a RAID subsystem in an environment
where multiple RAID subsystems reside.
♦ Unique Identifier (HEX)
This is a MUST for subsystem configuration, especially for those
with dual-controllers or Fibre host ports. The unique ID is integrated
as unique Fibre Channel node name and port names. In the event of
controller failover and failback, this ID helps host-side initiators to
identify a RAID subsystem.
♦ Time Zone(GMT)
GMT (Greenwich Mean Time) is used with a 24-hour clock. To
change the clock to your local time zone, select a time from the
drop-down menu. Choose the hour later than the Greenwich mean
time following a plus (+) sign. For example, enter “+9” for Japanese

♦ Upload NVRAM to Host Disk. This allows you to backup your
controller-dependent configuration information to a system drive.
We strongly recommend using this function to save the
configuration profile whenever a configuration change is made.
♦ Save NVRAM to Disk. The configuration profile can also be saved
to array hard drives. Each array hard drive will have a replica of the
NVRAM backup in its reserved space so that when a drive fails or is
being regrouped, the backup remains intact.
♦ Restore NVRAM from Disk. Retrieve the previously saved NVRAM
backup from array hard drives.

displays if your controller/subsystem comes with dual-redundant RAID
controllers.
♦
Secondary Controller RS-232 Terminal: In a redundant controller
configuration, the RS-232C port on the Secondary controller is
normally nonfunctional. Enable this function if you wish to use the
port for debugging purposes.
NOTE:
Access to the Secondary controller only allows you to see controller
settings. In a redundant configuration, configuration changes have to be
made through the Primary controller.
7-10
♦
Remote Redundant Controller: You can enable or disable the
remote management on the redundant controller.
♦
Cache Synchronization on Write-Through: If redundant
controllers work with Write-Back caching, it is necessary to
synchronize the unfinished writes in both controllers’ memory.
Cache synchronization lets each controller keep a replica of the
unfinished writes on its partner, so that if one of the controllers fails,
the surviving controller can finish the writes.
Redundant Controller Settings
Chapter 7: Configuration Parameters
If controllers are operating using the Write-Through caching mode,
the synchronized cache operation can be manually disabled to save
system resources and achieve better performance.
NOTE:
If sync. cache is disabled, the configuration changes made through the
Primary controller is still communicated to the Secondary controller.
♦
Adaptive Write Policy: Firmware is embedded with intelligent
algorithms to detect and to adapt the array’s caching mode to the I/O
requests characteristics. The capability is described as follows:
1.
When enabled, the adaptive write policy optimizes array
performance for sequential writes.
2.
The adaptive policy temporarily disables an array’s write-caching
algorithm when handling sequential writes. Write-caching can be
unnecessary with sequential writes so that write requests can be
more efficiently fulfilled by writing data onto disk drives in the
order in which they are received.
3.
The adaptive policy changes the preset write policy of an array
when handling I/Os with heterogeneous characteristics. If the
firmware determines it is receiving write requests in sequential
order, the write-caching algorithm is disabled on the target logical
drives.
If subsequent I/Os are fragmented and received randomly, the
firmware automatically restores the original write-cache policy of
the target logical drives.
Adaptation for Redundant Controller Operation
4.
If arrays managed by a redundant-controller configuration are
configured to operate with write-back caching, cached data will be
constantly synchronized between the partner controllers. Upon
receiving sequential writes, the firmware disables write-caching on
target arrays and also the synchronized cache operation.
IMPORTANT!
The Adaptive Write Policy is applicable to subsystems working under normal
conditions. For example, if a drive fails in an array, the firmware
automatically restores the array’s original write policy.
For the setting to take effect, click Apply.

Each function is executed by a two-step procedure: Click to select a desired
value from the pull-down menu, and then click Apply for the configuration

resetting the subsystem.
Drive-side Parameters
Disk Access Delay Time (Sec): Sets the delay time before the
subsystem tries to access the hard drives after power-on. Default is 15
seconds.
Drive Check Period (Sec): This is the time interval for the controller
to check all disk drives that were on the drive buses at controller
startup. The default value is “Disabled.” Disabled means that if a
drive is removed from the bus, the controller will not know it is
missing as long as no host accesses that drive. Changing the check
time to any other value allows the controller to check all array hard
drives at the selected time interval. If any drive is then removed, the
controller will be able to know – even if no host accesses that drive.
Auto-assign Global Spare Drive: Enable this function to allow the
system to auto-assign the Global Spare drive.
SCSI Motor Spin Up. Selected when hard drives need to Spin-up by
SCSI command. By default, all hard drives will start spinning up

when powered-on. Also refer to the documentation that came with
your hard drives.
SMART: This allows you to configure SMART-related functionality.
SMART is short for “Self-Monitoring, Analysis and Reporting
Technology.” Options provided in the pull-down menu are the
actions to be taken if the SMART function detects an unstable drive.
Disk I/O Timeout (Sec): This is the time interval for the subsystem to
wait for a drive to respond to I/O requests. Selectable intervals range
from 1 to 10 seconds.
SAF-TE/SES Device Check Period (Sec): If enclosure devices in
your RAID enclosure are being monitored via SAF-TE/SES, use this
function to decide at what interval the subsystem will check the status
of these devices.
Drive Fail Swap Check Period (Sec): The subsystem scans drive
buses at this interval to check if a failed drive has been replaced.
Maximum Tag Count: The subsystem supports tag command
queuing with an adjustable maximum tag count from 1 to 128. The
default setting is “Enabled” with a maximum tag count of 32.
Host-side Parameters
Maximum Queued I/O Count: This is the arrangement of the
controller internal resources for use with a number of the current host
nexus. It is a "concurrent" nexus, so when the cache is cleared up, it
will accept a different nexus again. Many I/Os can be accessed via
the same nexus.
This function allows you to configure the maximum number of I/O
queues the controller can accept from the host computer.
LUNs per Host ID: Each SCSI ID can have up to 32 LUNs (Logical
Unit Numbers). A logical configuration of array capacity can be
presented through one of the LUNs under each host channel ID. Most
SCSI host adapters treat a LUN like another SCSI device.
An additional function is available if you are using an EonStor iSCSI
series model. (See Figure 7-11)

Login Authentication with CHAP allows you to enable or disable the
login authentication with the Challenge Handshake Authentication
Protocol (CHAP) function. CHAP enables the username and
password to be encrypted against eavesdroppers.
Disk-Array Parameters
Rebuild Priority: The rebuild priority determines how much of the
system resources are applied when rebuilding a logical drive.
Available options are Low, Normal, Improved, and High. The higher
priority takes up more system resources and the rebuild process
completes more rapidly. However, I/O performance in the meantime
is inevitably lower due to the resources consumed.
Write-Verify Options: Errors may occur when a hard drive writes
data. In order to avoid write errors, the controller can force the hard
drives to verify the written data. There are three selectable methods:
1.
Verification on LD Initialization Writes:
Performs Verify-after-Write while initializing the logical drive.
2.
Verification on LD Rebuild Writes:
Performs Verify-after-Write during the rebuilding process.
3.
Verification on LD Normal Drive Writes:
Performs Verify-after-Write during normal I/O requests.

RAIDWatch User’s Manual
Maximum Drive Response Timeout (ms): This option prepares the
array for applications featuring “no drop-frame” operations and
continuous reading such as video streaming.
In situations such as swapping a failed drive or the occurrence of bad
blocks, a read returned after 30 or 50ms would prove too long and
cause choppy audio or dropped video frames.
To ensure a response before guaranteed latency, a timeout value is
provided for processing read requests. If a timeout is reported on a
specific member of an array, the subsystem immediately retrieves
data from the parity data and other members. In this way, causes of
delay can be eliminated.
To prepare the array for AV applications, the following are
recommended:
1.
Performance with the Write-Through caching mode is better
than the Write-Back mode on subsystems equipped with
redundant RAID controllers.
2.
Arrays should not be partitioned.
3.
The priorities for Rebuild or Add-drive expansion should be
set to “low.”
4.
A maximum latency, the “Drive I/O Timeout” which
determines whether a drive has failed to respond to I/O
requests, is required as the first-level timeout.
The option comes available with an OEM append file. The following
options in the internal settings are pre-adjusted:
7-16
1.
Reads have higher priority.
2.
The Smart Sorting algorithm is disabled to avoid latency that
may arise due to sorting. The firmware is forced to receive
ordered read requests, i.e., the original receiving order.

Channel Configuration
Using RAIDWatch Manager, you can modify the configuration of any
channel on the controller. With RAID controllers like the EonRAID
2510FS, you can set the channel operation mode to host or drive, enable or
disable channel termination, set IDs, set the transfer clock rate for
synchronous communication, and select the transfer width.
Channel configuration settings are available under Physical View in the

Channel Mode
This configuration option is exclusively available with the EonRAID
2510FS series.
The EonRAID series controller allows flexible reconfigurations of its I/O
channels. An I/O channel can be assigned as Host, Drive, dedicated RCC
(RCCOM), or Drive+RCCOM channels. For example, the combination of
I/O channels may look like the following:
Dual-Redundant Controller Models
EonRAID 2510FS4RH
2 hosts and 2 drive+RCCOMs; a total of 4 I/O
channels
EonRAID 2510FS6RH
2 hosts, 2 dedicated RCCOMs, and 2 drives; a
total of 6 I/O channels

User-Configurable Channel Parameters
Chapter 8: Channel Configuration
8.2.2.
Termination
This parameter enables or disables channel SCSI termination on subsystems
featuring SCSI host channels. SCSI buses must be properly terminated at
both ends; that is, when connecting one end of a SCSI cable to a host HBA,
the termination of the channel must be enabled on the subsystem side. An
alternate configuration should be applied when multiple enclosures are
being cascaded on the host buses. An enclosure situated in the middle of a
SCSI bus should have its termination set to disabled.
8.2.3.
Default Transfer Clock (in MHz)
These parameters set the data transfer clock rate for synchronous
communication over the SCSI bus, and enable or disable wide transfer,
respectively.
Data transferred across the bus in synchronous transfer mode is clocked
using a synchronous transfer clock signal. The frequency of this signal
determines the rate at which data is transferred. For example, if the
synchronous transfer clock is 10 MHz, data transfer rate will be 10 million
bytes per second (using narrow transfer).
Data transfer across the SCSI bus can be either 8-bits or 16-bits at a time.
The former is referred to as narrow transfer, while the latter is referred to as
wide transfer. According to SCSI channel specifications, transfer speed
shown in MHz is the SCSI bus synchronous frequency. At the same
synchronous transfer clock rate, 16-bit wide transfer rate is double of 8-bit
narrow transfer rate. Please refer to the transfer speed in the table below.
Transfer Rate
Clock Speed in MHz
SCSI-320
160MHz
SCSI-160
80MHz
Table 8-3: SCSI Channels Clock Speeds
NOTE:
Infortrend’s SCSI products are backward compatible with older version
of SCSI type. However, using older versions of SCSI type may slow
down the data transferring speed and do not enjoy some of the new SCSI
features.
Under conditions in which SCSI signal quality is poor, such as with
extremely long cables, poor connections, or bad termination, it may
occasionally be necessary to reduce the synchronous transfer clock to allow
the SCSI channel to function normally. Worst case, it may be necessary to
switch to asynchronous communication mode.
User-Configurable Channel Parameters
8-5
RAIDWatch User’s Manual
Furthermore, certain older SCSI devices may only support narrow transfer
and behave abnormally when attempting to negotiate wide transfer. Under
such conditions, wide transfer may need to be disabled, forcing the
controller to use narrow transfer mode with that device.
IMPORTANT!
Every time you change the transfer speed, you must reset the controller
for the changes to take effect.
8.2.4.
ID Pool / PID / SID
The selection with PID (Primary ID) and SID (Secondary ID) only appears
with controller/subsystems that come with dual-redundant RAID controllers.
This parameter sets the IDs to appear on the host channels. Each channel
must have a unique ID in order to work properly. For a SCSI-host
subsystem, IDs range from 0 to 15. For an iSCSI-host subsystem, IDs range
from 0 to 3. For a Fibre-host controller/subsystem, IDs range from 0 to 125.
ID 0 is the default value assigned for host channels on SCSI-host and iSCSIhost subsystems and ID 112/113 is the default value assigned for host
channels on Fibre-host controller/subsystems. Preset IDs are available with
drive channels and it is recommended to keep the defaults.
For more information on host channel and drive channel IDs, please refer to
the Generic Operation Manual and the hardware documentation that came
with your controller/subsystems.
8.3 Setting the Configurations for a Channel
Step 1. Single-click under the Channel window to select a corresponding
channel. Channel icons are displayed in the left-side panel of the
configuration window. The Channel Settings configuration will
appear as two separate pages on the right side: Parameters and ID.
(See Figure 8-1).
Step 2. From the Parameters panel, specify a preferred value with
configurable items either by checking the pull-down menus or
radio buttons of the transfer clock, transfer width, termination,
and/or parity check. Be sure to click Apply for the changes to take
effect.
Step 3. If you want to assign a different ID to the selected channel, choose
the ID panel. An ID pool scroll menu will appear as shown in
Figure 8-5.

Dynamic Logical Drive Expansion
9.2.4.1.
What Is It and How Does It Work?
Before Dynamic Logical Drive Expansion, increasing the capacity of a
RAID system using traditional methods meant backing up, re-creating,
and then restoring data. Dynamic Logical Drive Expansion (a new
feature in controller firmware versions 2.11 and later) allows you to add
new hard disk drives and expand a RAID 0, 3 or 5 logical drive without
powering down the system.
9.2.4.2.
Two Modes of Dynamic LD Expansion
There are two modes of Dynamic Logical Drive Expansion.
Mode 1 Expansion is illustrated in Figure 9-6 and involves adding more
hard disk drives to a logical drive, which may require that the purchase of
an enclosure with more drive bays. The data will be re-striped onto the
original and newly added disks.
9-10
Logical Drive Management
Chapter 9: Drive Management
Figure 9-6: RAID Expansion Mode 1
In Figure 9-6 above, new drives are added to increase the capacity of a
4-Gigabyte (GB) RAID 5 logical drive. The two new drives increase the
capacity to 8GB.
Mode 2 Expansion, on the other hand, requires the same number of
higher-capacity hard disk drives for a given logical drive.
Figure 9-7: RAID Expansion Mode 2 (1/3)
Figure 9-7 above illustrates expansion of the same 4GB RAID 5 logical
drive using Mode 2 Expansion. Drives are copied and replaced, one by
one, onto three higher-capacity drives.

Chapter 9: Drive Management
When you return to the partition table, you will notice that either partition
0 or the last partition will now be larger than before.
Follow the directions in the next chapter to map the new partition to a
host LUN. The new partition must be mapped to a host LUN in order for
the HBA (host-bus adapter) to see it.
9.2.5
Adding Spare Drive Assignments
You can assign spare drives to a logical drive to serve as backups for
failed drives. In the event of a drive failure, the spare drive will be
automatically configured into the array and reconstruction (or rebuilding)
will immediately commence.
Logical drives can support multiple spare drives; however, this
configuration is rarely used due to its high cost and the uncommon
occurrences of drive failures. A practical configuration calls for one spare
drive per logical drive. After rebuilding on this drive, just replace the
failed drive and then configure the replacement as the new spare drive.
NOTE:
Adding a spare drive can be done automatically by selecting the RAID
1+Spare, RAID 3+Spare or RAID 5+Spare option from the logical
drive RAID Level selection dialog box when creating a logical drive.
These options apply to RAID 1, RAID 3, and RAID 5 levels
respectively.
9.2.5.1.
Accessing the Spare Drive Management
Screen
To open the Spare Drive Management screen, please follow these steps:
Step 1. Select the logical drive to which you wish to add a dedicated
spare from the list of the logical drives above. In the Functions
window, click the Add Disk tab. The functional window is
accessed from the Existing Logical Drives window as shown in
Figure 9-10, the Add Spare button appears next to the Add Disk
button.
Figure 9-10: The “Add Spare Drive” Button
Logical Drive Management
9-13
RAIDWatch User’s Manual
Step 2. From the Front View window, select the disk drive you want to
use as a dedicated spare with a single mouse-click.
Step 3. After selecting the drive that will be used as a spare, the selected
drive’s status will be displayed and you may click the Add Spare
button to complete the process.
NOTE:
Spare drive assignments can also be made in the Maintenance mode
window. Note that a Global Spare cannot be added in the Existing
Logical Drives window.
9.2.6
Rebuilding Logical Drives
Depending on whether or not there is a spare drive, rebuilding is initiated
automatically or must be started manually. In the presence of a spare
drive, the system automatically rebuilds onto the spare drive. This
process is done in the background, thus it is transparent to users.
However, you should replace the failed drive as soon as possible and
insert a new drive and set it as a spare just in case another drive fails and
you will need a backup drive.
In the absence of a spare drive, rebuilding must be initiated manually.
Before initiating a manual rebuild, you must first replace the failed drive.
If you install the replacement drive in the same drive slot (that is, the
same channel and ID), then you can proceed with the rebuilding process
by clicking on the Rebuild button; otherwise, you need to scan in the
drive first.
A failed drive should be replaced as soon as possible. For a RAID 3 or
RAID 5 array, two failed members will cause an irrecoverable loss of
data.
The controller/subsystem can be set to rescan the drive bus for a
replacement drive at preset intervals. The related setting can be found in
Configuration Parameters -> Other -> Drive Side Parameters -> Drive
Fail Swap Check Period in second.

Deleting an LD
If you want to delete an LD from your RAID subsystem, follow the steps
outlined below. Remember that deleting an LD results in all the data on
the LD being deleted and any data that was previously stored on the LD
will be irretrievable.
IMPORTANT!
Deleting a logical drive irretrievably wipes all data currently stored on
the logical drive.
Step 1. Select the logical drive you wish to remove with a single mouseclick. Right-click on the adjacent screen area. A command menu
will prompt as shown in Figure 9-12.

9.3.4
To Expand a Logical Volume
When members of a logical volume have free and unused capacity, the
additional capacity can be added to existing logical volumes. The unused
capacity can result from the following situations:
•
Certain amount of capacity was intentionally left unused when the
logical drives were created (configurable with maximum array
capacity).
•
Some or all of the members of a logical volume have been expanded,
either by adding new drives or copying and replacing original drives
with drives of larger capacity.
9.3.4.1.
Opening the Expand Logical Volume
Window
Step 1. Select a configured LV from the Existing Logical Volumes
window shown in Figure 9-16. As shown below, all the LVs that
have been created will appear below the Logical Volume Status
panel.
Creating and Deleting Logical Volumes
9-19
RAIDWatch User’s Manual
Figure 9-16: Existing Logical Volumes Window
Step 2. The expand command can be found by clicking the Expand tab
under the LV Parameters panel.
Figure 9-17: Logical Volume Parameters
Step 3. Available expansion size displays in a text box if there is any
amount of unused capacity.
Step 4. Click the Expand button at the bottom of the configuration panel.
The expand process should be completed in a short while because
all unused capacity in the members of a logical volume must be
made useful by the same expansion process. The expansion
process on a logical volume simply lets subsystem firmware
recognize the change in the arrangement of free capacity.
NOTE:
You may combine partitions under View and Edit LV Partition Table
by expanding the size of earlier partitions (such as increasing the size
of partition 0 so that it is as large as all partitions combined to make
one partition).
WARNING!
Combining partitions destroys existing data on all drive partitions.

9.4. Partitioning a Logical Configuration
9.4.1
Overview
Partitions can be created in both logical drives (LD) and logical volumes
(LV). Depending on your specific needs, you can partition an LD or LV
into smaller sizes or just leave it at its default size (that is, one large
partition covering the entire LD or LV).
If you intend to map an entire LD or LV to a single host LUN, then
partitioning becomes irrelevant. Partitioning can be helpful when dealing
with arrays of massive capacities and when rearranging capacities for
applications that need to be accessed by many hosts running
heterogeneous OSs.

LUN Mapping
After creating a logical drive (LD) or logical volume (LV), you can map
it as is to a host LUN; or, if partitions are set, you can map each partition
to a specific host LUN. RAIDWatch supports eight LUNs per host
channel (numbered 0 - 7), each of which appears as a single drive letter
to the host if mapped to an LD, LV, or a partition of either. Existing host
LUN mappings can also be deleted. In cases where certain mappings are
found to be useless, or the disk array needs to be reconfigured, you can
delete unwanted mappings in your system.

RAID Information
Unlike its predecessor, RAIDWatch presents access to all informational
services under one Array Status category. Users logged in using the
Information authorization will be allowed to access the information
windows while being excluded from other configuration options.
Support for device monitoring via SAF-TE, SES, and I2C data buses is
the same. However, RAIDWatch now uses a more object-oriented
approach by showing the enclosure graphics, which are identical to your
EonRAID or EonStor enclosures. RAIDWatch reads identification data
from connected arrays and presents a correct display as an enclosure
graphic. This process is automatically completed without user’s setup.
NOTE:
RAIDWatch does not support the display of drive enclosures provided
by other vendors.

Logical Drive Information
Logical Drive Information helps you to identify the physical locations
and logical relationship among disk drive members. In a massive storage
application, a logical array may consist of disk drives installed in
different drive enclosures.
The Logical Drive information is designed for today’s complicated
configurations of RAID arrays. The information window helps to achieve
the following:
♦ Having a clear idea of the logical relationship can help avoid
removing the wrong drive in the event of drive failure. A logical

drive (RAID) configuration of disk drives cannot afford two failed
disk drives.
♦ A logical drive may include members that reside on different
enclosures or different drive channels. Doing so can help reduce the
chance of downtime if a hardware failure should occur.
♦ With operations such as manual rebuild or capacity expansion using
the “Copy and Replace” methodology, it is crucial to correctly
identify an original member and a replacement drive.

About The Enclosure View Window
The RAIDWatch Enclosure View is a specialized customization that shows
a visual representation of physical RAID controller/subsystem components
in the Enclosure View window of the RAIDWatch screen. The Enclosure
View allows you to quickly determine the operational status of critical
RAID device components.
The Enclosure View window shows both the front and rear panel (e.g., the
EonRAID 2510FS controller head series, see Figure 12-1). The Enclosure
View of each RAIDWatch session defaults to the display of the connected
RAID controller or RAID subsystem. The tabbed panel provides access to
other cascaded enclosures (e.g., JBODs, the EonStor series, see Figure
12-2), so you can monitor multiple enclosures by your computer screen.

Component Information
The front and rear view of a RAID system in the Enclosure View window
presents a graphical display of different components. This window is
particularly useful in monitoring the status of the physical drives. It provides
a real-time report on the drive status, using LED colors to represent various
operating conditions.
Using the RAIDWatch Enclosure View, it is possible to obtain information
about the following RAID device components:
♦
RAID Controller – The RAID controller is the heart of any RAID
device and controls the flow of data to and from the storage
devices.
♦
I/O Channels – An I/O channel is the channel through which data
flows to and from the RAID controller.
♦
Battery Backup Unit (BBU) – The BBU provides power to the
memory cache when power outage occurs or the power supply
units fail.
NOTE:
The BBU is an optional item for some subsystem models.
♦
Power Supply Unit (PSU) – All RAID devices should come with at
least one PSU that provides power to the RAID device from the
main power source.
♦
Cooling Module – All RAID devices should come with at least one
cooling module. The cooling modules keep the RAID device
temperature down to prevent the RAID device from overheating.

LED Representations
As described earlier (see Section 12.1), the Enclosure View is a direct
representation of the physical device. Almost every major component has its
status-indicating LEDs. When a component fails (or some other event
occurs), the related LEDs will flash or change the display color. The
physical status of the LEDs will be reflected by the LEDs shown in the
Enclosure View window. That is, if an LED on the physical device changes
its display color, then the display color of the corresponding LED in the
Enclosure View window will also change.
Figure 12-4: Enclosure Tabbed Panel and Component LED Display
The definition for each LED has been completely described in the
Installation and Hardware Reference Manual that came with your RAID
controller/subsystem. Please refer to the manual to determine what the
different LEDs represent.

Enclosure View Messages
The messages shown in the Enclosure View window provide easy access to
information about components on the RAID device that is being monitored.
The message tag reports the status of major devices.
Figure 12-5: Component Information Message Tags
To generate the message tags, move the mouse cursor onto the relevant
RAID device component. For example, if you wish to determine the
operational status of a RAID subsystem, move the cursor onto the enclosure
graphic and the corresponding message tag will appear.
The enclosure front view message tag displays the current configuration of
the drive, including the channel number of the drive slot on the subsystem to
which the drives are connected, the drive’s capacity, transfer rate, and
current status.
The enclosure components displays as a summary of module operating
status. The operating status of each module is shown either as operating
normally or failed.
NOTE:
Messages do not always appear instantaneously. After the cursor has
been moved onto the component, there is usually a delay of a second
before the message tag appears.
NOTE:
More device-dependent information is provided in the System
Information window. To access the System Information window, please

13.1. The NPC Utility
13.1.1
Introduction
NPC is stands for “Notification Processing Center.” This utility is used to
send event messages when the main RAIDWatch modules are installed to a
RAID subsystem’s segregated disk capacity, the reserved space. NPC is
implemented to manage event notification functions since the Configuration
Client utility is not available with the Mode 3 installation scheme. With
Mode 3 installation, arrays are accessed directly through network
connections without installing the manager software and utilities onto a
server. The NPC utility is automatically distributed to a disk array's reserved
space when installing RAIDWatch using the Mode 3 scheme.
13.1.2
To Access the Utility
The NPC utility is easily accessed using a web browser over the network.
Step 1. Open a web browser program.
Step 2. Enter "http://<controller IP>/configure.htm" in the web
browser's URL field.
Step 3. A safe content warning message might prompt. Click Yes to
proceed. (See Figure 13-1)

Parity checking is used to detect errors in binary-coded data. The
fact that all numbers have parity is commonly used in data
communications to ensure the validity of data. This is called parity
checking.
RAID
Redundant Arrays of Independent Disks (Originally “Redundant
Arrays of Inexpensive Disks”). The use of two or more disk drives
instead of one disk, which provides better disk performance, error
recovery, and fault tolerance, and includes interleaved storage
techniques and mirroring of important data. See 0.
RAID Agent
The RAIDWatch module which manages and monitors a RAID
controller and receives RAIDWatch Manager commands via the
RAID Agent.
RAID Agent comes embedded with RAID array firmware. RAID
Agent can also be manually installed onto a server which is

are instead “hot-ready” and used to automatically replace a failed
drive. RAIDs generally support two types of spare, Local and
Global. Local Spares only replace drives that fail in the same
logical drive. Global Spares replace any drive in the RAID that
fails.
Stripe
A contiguous region of disk space. Stripes may be as small as one
sector or may be composed of many contiguous sectors.

Glossary

Striping
Also called RAID 0. A method of distributing data evenly across
all drives in an array by concatenating interleaved stripes from each
drive.
Stripe Size
(A.k.a. “chunk size.”) The smallest block of data read from or
written to a physical drive. Modern hardware implementations let
users tune this block to the typical access patterns of the most
common system applications.
Stripe Width
The number of physical drives used for a stripe. As a rule, the
wider the stripe, the better the performance.
Write-back Cache
Many modern disk controllers have several megabytes of cache on
board. Onboard cache gives the controller greater freedom in
scheduling reads and writes to disks attached to the controller. In
write-back mode, the controller reports a write operation as
complete as soon as the data is in the cache. This sequence
improves write performance at the expense of reliability. Power
failures or system crashes can result in lost data in the cache,
possibly corrupting the file system.
Write-through Cache
The opposite of write-back. When running in a write-through
mode, the controller will not report a write as complete until it is
written to the disk drives. This sequence reduces read/write
performance by forcing the controller to suspend an operation
while it satisfies the write request.

Appendix C.
RAID Levels
This appendix provides a functional description of Redundant Array of
Independent Disks (RAID). This includes information about RAID and
available RAID levels.
C.1. RAID Description
Redundant Array of Independent Disks (RAID) is a storage technology used
to improve the processing capability of storage systems. This technology is
designed to provide reliability in disk array systems and to take advantage of
the performance gains multiple disks can offer.
RAID comes with a redundancy feature that ensures fault-tolerant,
uninterrupted disk storage operations. In the event of a disk failure, disk
access will still continue normally with the failure transparent to the host
system.
RAID has several different levels and can be configured into multi-levels,
such as RAID 10, 30, and 50. RAID levels 1, 3 and 5 are the most
commonly used levels, while RAID levels 2 and 4 are rarely implemented.
The following sections described in detail each of the commonly used RAID
levels.
RAID offers the advantages of Availability, Capacity, and Performance.
Choosing the right RAID level and drive failure management can increase
data Availability, subsequently increasing system Performance and storage
Capacity. Infortrend external RAID controllers provide complete RAID
functionality and enhance drive failure management.
C.2. Non-RAID Storage
One common option for expanding disk storage capacity is simply to install
multiple disk drives into the system and then combine them end-to-end.
This method is called disk spanning.
In disk spanning, the total disk capacity is equivalent to the sum of the
capacities of all SCSI drives in the combination. This combination appears
to the system as a single logical drive. For example, combining four 1GB
drives in this way would create a single logical drive with a total disk
capacity of 4GB.
Disk spanning is considered non-RAID due to the fact that it provides
neither redundancy nor improved performance. Disk spanning is
inexpensive, flexible, and easy to implement; however, it does not improve
the performance of the drives and any single disk failure will result in total
data loss.

C.3. RAID 0
RAID 0 implements block striping where data is broken into logical blocks
and striped across several drives. Although called RAID 0, this is not a true
implementation of RAID because there is no facility for redundancy. In the
event of a disk failure, data is lost.
In block striping, the total disk capacity is equivalent to the sum of the
capacities of all drives in the array. This combination of drives appears to
the system as a single logical drive.
RAID 0 provides the highest performance without redundancy. It is fast
because data can be simultaneously transferred to/from multiple disks.
Furthermore, read/writes to different drives can be processed concurrently.

C.4. RAID 1
RAID 1 implements disk mirroring where a copy of the same data is
recorded onto two sets of striped drives. By keeping two copies of data on
separate disks or arrays, data is protected against a disk failure. If a disk on
either side fails at any time, the good disks can provide all of the data
needed, thus preventing downtime.
In disk mirroring, the total disk capacity is equivalent to half the sum of the
capacities of all drives in the combination. For example, combining four
1GB drives would create a single logical drive with a total disk capacity of
2GB. This combination of drives appears to the system as a single logical
drive.
RAID 1 is simple and easy to implement; however, it is more expensive as it
doubles the investment required for a non-redundant disk array
implementation.

Figure C-3: RAID1 Storage
In addition to the data protection RAID 1 provides, this RAID level also
improves performance. In cases where multiple concurrent I/Os are
occurring, these I/Os can be distributed between two disk copies, thus
reducing total effective data access time.
C.5. RAID 1(0+1)
RAID 1(0+1) combines RAID 0 and RAID 1 – mirroring and disk striping.
RAID (0+1) allows multiple drive failure because of the full redundancy of
the hard disk drives. If more than two hard disk drives are chosen for RAID
1, RAID (0+1) will be performed automatically.
IMPORTANT!
RAID (0+1) will not appear in the list of RAID levels supported by the
controller. If you wish to perform RAID 1, the controller will determine
whether to perform RAID 1 or RAID (0+1). This will depend on the
drive number that has been selected for the logical drive.

C.6. RAID 3
RAID 3 implements block striping with dedicated parity. This RAID level
breaks data into logical blocks, the size of a disk block, and then stripes
these blocks across several drives. One drive is dedicated to parity. In the
event a disk fails, the original data can be reconstructed from the parity
information.
In RAID 3, the total disk capacity is equivalent to the sum of the capacities
of all drives in the combination, excluding the parity drive. For example,
combining four 1GB drives would create a single logical drive with a total
disk capacity of 3GB. This combination appears to the system as a single
logical drive.
RAID 3 provides increased data transfer rates when data is being accessed
in large chunks or sequentially.
However, in write operations that do not span multiple drives, performance
is reduced since the information stored in the parity drive needs to be
recalculated and rewritten every time new data is written to any of the data
disks.

C.7. RAID 5
RAID 5 implements multiple-block striping with distributed parity. This
RAID level offers the same redundancy available in RAID 3, though the
parity information is distributed across all disks in the array. Data and
relative parity are never stored on the same disk. In the event a disk fails,
original data can be reconstructed using the available parity information.
For small I/Os, as few as one disk may be activated for improved access
speed.
RAID 5 offers both increased data transfer rates when data is being accessed
in large chunks or sequentially and reduced total effective data access time
for multiple concurrent I/Os that do not span multiple drives.

C.8. RAID 10, 30, and 50
Infortrend implements RAID 10, 30, and 50 in the form of logical volumes.
Each logical volume consists of one or more logical drives. Each member
logical drive can be composed of a different RAID level. Members of a
logical volume are striped together (RAID 0); therefore, if all members are
RAID 3 logical drives, the logical volume can be called a RAID 30 storage
configuration.
Using logical volumes to contain multiple logical drives can help manage
arrays of large capacity. It is, however, difficult to define the RAID level of
a logical volume when it includes members composed of different RAID
levels.
