Chapter 1: Introduction
Promise Array Management (PAM) is a utility application designed
specifically for monitoring and managing Promise Technology RAID
products. PAM runs over a local area network and makes possible RAID
monitoring and management from any computer on the network and even
over Internet. This allows your IT manager to watch your RAIDs and take
care of them over the network.
PAM Components
There are three components to PAM. Depending on your installation, all
three may be on the same workstation or work separately across your
network:
Monitoring Utility ― The Monitoring Utility is a Graphic User Interface
(GUI) that reports on the condition of the RAID array. It receives and displays
reports on RAID condition and operation through the Message Server. The
Monitoring Utility works on any PC with a TCP/IP network connection to your
RAID.
When installed on the computer that operates the RAID, the Monitoring
Utility also provides a complete set of RAID management tools.
Message Server ― The Message Server is the link connecting a PC with
the Monitoring Utility. Normally, the Message Server runs on a network file
server. But it can also run on the PC controlling the RAID.
Message Agent ― The Message Agent runs on the PC that controls the
RAID. It directly monitors the RAID and sends messages through the
Message Server to all PCs running the Monitoring Utility.
1
Promise Array Management
How They Work Together
The Promise Array Management (PAM) utility provides an easy way to set
up, monitor, modify and repair your RAID. PAM works with the Promise
FastTrak card, SuperTrak card and UltraTrak RAID subsystem.
PAM watches the RAID and when significant events happen, or it discovers
a problem, the Message Agent sends a warning to the Message Server. The
Message Server passes the warning along to all PCs running the Monitoring
Utility.
Warnings appear on the PC in the form of email messages and popup alerts.
You can select either one or both. You can also select which events and
problems PAM will report.
A major benefit of PAM is that it runs over a TCP/IP network. This enables
remote monitoring of your RAIDs, including offsite monitoring over an
Internet connection.
Once you become aware of a problem, go to the RAID PC to take corrective
action. If you have more than one RAID PC on your network, PAM will
indicate which one has the problem.
PAM allows only monitoring access through the network. Management
access occurs only at the RAID PC.

In the above example, there are three Promise RAID products connected to
the company’s LAN, the same as before. But this network has no file server,
so the PAM Message Server runs on one of the networked PCs. PAM
Monitoring Utility runs on both networked PCs. If this LAN were upgraded
with a suitable router and an Internet connection, you could set up offsite
monitoring as in Figure 1-1.

Chapter 2: Installation
To install Promise Array Management (PAM) is an uncomplicated procedure,
once you understand your systems and how you want to use PAM. The
purpose of this Chapter is to help you plan and carry out your installation of
PAM.
By way of review, PAM consists of three components:
• Monitoring Utility
• Message Server
• Message Agent
These were described in the previous chapter. Before proceeding with the
installation, you must know which component goes where. If you plan to run
PAM over a network, you must know the IP addresses of each computer on
the network that will be involved in your RAID monitoring and management
activity.
Installation Locations
In the table below, possible locations are indicated for each of the three PAM
components.

Monitoring Utility
The Monitoring Utility installs on any computer you will use to monitor and
manage the RAIDs.
If your RAID runs without a network connection, install it on the RAID PC
with the rest of the PAM components.
If your RAIDs are networked, you can install the Monitoring Utility on any
computer connected to the network.
7
Promise Array Management
If your company has networked RAIDs and Internet access, you may choose
to install the Monitoring Utility on a laptop or home-based PC for dial-in
remote access.
Limit your installation to the computers of RAID users and your IT
administrator. PAM features password protection to further limit access and
provide security of your data.

Chapter 2: Installation
Message Server
The Message Server installs onto the RAID PC if your installation does not
involve a network.
If you want run PAM over a network, install the Message Server on one of
your networked computers including a file server, a networked PC or the
RAID PC.
Only one installation of the Message Server is required for PAM to work over
a network. You may install Message Server on more than one network PC or
file server, but PAM’s network configuration will only use one of them, thus
any additional installations are not necessary.
Do not install the Message Server on any PC that may be disconnected from
the network, such as a laptop or a computer that connects via the Internet.
Not only will a disconnect cause PAM to fail, but reconnecting again may
involve time-consuming network configuration.
Network configuration is discussed later in this chapter. Refer to Table 2-2
for acceptable operating systems.

Message Agent
The Message Agent installs on the RAID PC, whether your RAID is
networked or not. In order for PAM to monitor and manage a RAID, it must
have Message Agent installed.
If you have more than one PAM-compatible RAID PC on your network, you
may install a copy of Message Agent on all of them.

Operating System Support
PAM is a utility designed to run on top of previously installed Promise
controller card and RAID products. Generally, if your PC runs the Promise
card or RAID properly, it will run PAM also.
Promise Technology recommends Windows NT 4.0, 2000 and XP
Professional to take full advantage of all the features of PAM. In some
cases, you can run PAM on other Windows operating systems. This
becomes an issue when running PAM over a network where there are PCs
with different operating systems.
The table below shows which versions of Windows work with specific
Promise products and PAM components.

Network Requirements
If you plan to install PAM on a network be sure all the hosts and servers are
connected and running. That is, each of the PCs, RAIDs and Servers must
have a working network connection before you install PAM.
In order for PAM to be configured over a network, you must know the IP
(network) address of the RAID PC(s) in your system. The Message Server
uses IP addresses to communicate with the Message Agent on the RAID
PCs and the Monitoring Utility on the network PCs.
See the Appendix for help in finding the IP Address of the RAID PC.
10
Chapter 2: Installation
Installation Procedure
Before you start…
If you are installing PAM to run over a network, determine the computers and
servers onto which you will install PAM. Obtain the IP addresses of all RAID
PCs where PAM will be installed.
UltraTrak Users
The UltraTrak is an external enclosure and must be online during PAM
installation. Follow these steps before you install PAM:
1. With your UltraTrak powered down, attach a null modem cable to the
UltraTrak serial port connector and one of the COM ports on your RAID
PC.
PAM will automatically detect the UltraTrak during installation.
2. Power up the UltraTrak and wait for it to boot completely.
3. Proceed with the PAM installation.
Note
PAM will manage one UltraTrak system per PC.

7. Click the Commit button in the Information View. The Options dialog box
appears. Check the box to enable:
Initialization ― Data on all drives is set to zero, effectively erasing any
data on the disks.
Gigabyte Boundary ― The Gigabyte Boundary feature is designed for
fault tolerant arrays (RAID 1, 0+1, 3 and 5) in which a drive has failed
and the user cannot replace the drive with the same capacity or larger.
Instead, the Gigabyte Boundary feature permits the installation of a
replacement drive that is slightly smaller (within 1 gigabyte) than the
remaining working drive (for example, an 80.5GB drive would be
rounded down to 80GB). This can be helpful in the event that a drive fails
and an exact replacement model is no longer available. Without this
feature enabled, a Promise RAID product will NOT permit the use of a
replacement drive that is slightly smaller than the remaining working
drive.
For the Gigabyte Boundary feature to work, the Gigabyte Boundary
feature must be set to ON when the original array is created. When
enabled, the Gigabyte Boundary feature rounds the drive capacity of all
drives to the common whole GB drive size. For example, with the
Gigabyte Boundary feature enabled, the remaining working drives can
be 80.5GB and the replacement drive can be 80.3, since all are rounded
down to 80GB. This permits the smaller drive to be used. Please note
that users will lose a small amount of available storage capacity from
each drives in order to arrive at a common drive size.
8. When you have made your selection,
click the Commit button on the
Options dialog box.
The Array Status field in the
Information View will show that the

Chapter 4: PAM User Interface
This chapter describes PAM’s Graphic User Interface (GUI). You should
understand that PAM is software running on top of the Promise RAID BIOS
and other applications that came with your Promise RAID product. PAM
adds a graphic user interface to make RAID management functions easier to
understand and perform.
Figure 4-1. The PAM Monitor window has three views.
33
Promise Array Manager
Tree View
The Monitor window is the user interface for PAM. It has three views: Tree
View, Object View and Information View which were introduced in Chapter 3.
The Tree View displays all of the elements of your RAID system. Use it to
navigate to specific components.
Figure 4-2. An example of a RAID system in Tree View.
Normally, the Tree View is present. To close it, right-click on any object and
select Hide Pane from the popup menu. To open it again, go to View menu
and Outline.
Tree View and Component Specific Menus
In PAM, like most Windows applications, you can access the various
commands and functions by opening dropdown menus and clicking on icons.
Each time you click on a component in Tree View, PAM’s menu bar also
displays that component’s dropdown menu. Below are some examples.
34
Chapter 4: User Interface
Figure 4-3. Each item in Tree View has its own dropdown menu in the menu
bar.
Rather than access the menu bar, you can right click on the icon of the
component you are working with. The menu bar and popup menus for Tree
View items are identical.
Object View
Object View is visible whenever the Tree View is visible. The items
appearing in Object View are determined by which component you select in
icon in Tree
Tree View. In the example below, we selected a Controller
View.
Figure 4-4. Object View of a Controller’s components.
As a result, you see the components of that Controller, in this case, six
channels, an enclosure and an array. This feature makes it easy to find an
individual component as well as see what items are assigned to higher level
components. Double-click on these items to see their components in Object
View and their configuration in Information View.
35
Promise Array Manager
Information View
Information View, like Object View, changes its content depending on which
item you select in Tree View. The difference is that you use Information View
to obtain data, input settings and information.
Figure 4-5. Information View showing part of the setup for an Array.
Status Bar
The PAM Status Bar is the same as other Windows applications. It indicates
such things as the selected RAID is rebuilding, and the current user is the
Administrator (shown below).
Figure 4-6. PAM Status Bar.
Normally the Status Bar is visible. To show or hide the Status Bar, go to the
View menu and check or uncheck Status Bar.
36
Chapter 4: User Interface
Pulldown Menus
As indicated above, the left-most item of the Pulldown Menus changes
according to which component is selected in the Tree View. The Pulldown
menu and popup (right-click) menus are the same.
Main
When no item in Tree View is selected, the left-most menu item is Main.
Figure 4-7. Main Menu.
Its only function is Exit, which quits the PAM application.
View
The View menu displays or hides three items:
•
•
•
Toolbar

Preference
The Preference menu allows you to:
•
•
•
Select the font PAM displays
Select the background colors of the Views
Have PAM run automatically when your PC boots
Figure 4-10. The Preference Menu.
Fonts and colors are a matter of individual preference. PAM will display any
font properly loaded on your PC. PAM uses the Windows color palette,
allowing you to select any color your monitor can display.
If you are using PAM for remote monitoring, running PAM automatically is a
good idea. This way, your PC will be connected to the RAID and you will
receive all the alerts messages you have specified.

Controller
The Controller deals with creating new Arrays, reading events from the
memory buffer, setting cache and performance options. Array creation is
covered in the Arrays section of this chapter.
Memory Buffer Events
The Controller’s Memory Buffer records all the events that
happen on the RAID, classified as Errors, Warnings and
Information. These are very useful for diagnosing and
solving problems on your system.

Rebuild Setting
High priority (box checked) assigns most of the system resources to
rebuilding. Rebuilding goes faster, restoring redundancy sooner but
read/write requests are handled slower.
Low priority assigns most of the system resources to handling read/write
requests. Read/write requests are handled at nearly normal speed while the
rebuild takes longer.
See Rebuild an Array later in this chapter for more information on the
rebuilding process.
Controller Setting
This feature applies to the SX6000 controller with the optional battery backup
unit. When Battery Backup Support is enabled and a power failure occurs,
the SX6000 will attempt to recover cached data from the SDRAM rather than
discarding it. This includes data waiting to be written to the hard drive at the
moment of the power failure.
Cache Setting
This option applies only when write-back cache is enabled (see Array
Options later in this chapter). Enter the maximum number of seconds data is
held in cache before being written to the hard drive, called flush frequency. A
longer period tends to increase apparent read/write performance but at a
greater risk of lost data should a power failure occur.
Disk Parameters: SMART Check
SMART, an acronym for Self-Monitoring Analysis and Reporting Technology,
is a feature of the disk drive software. It monitors the internal performance of
the drive and reports to the PC when it finds a potential failure. SMART
warns you of a developing drive failure so you can replace the drive before it
actually fails.
Disk Parameters: Enable Hard Disk’s Write Cache
Increases hard disk performance by writing data to the cache first and later
to the disk.
Caution
You can lose data if a power failure occurs while data is
still in the drive’s cache.
If any of these features are grayed out, it means they are not available on
your hard drives.

Rebuild Options: Disable Hot Spare/Auto Rebuild
For mirrored arrays (RAID 1 and 0+1), this option turns off the hot spare
drive and automatic rebuilding. The default is unchecked, hot spare and
automatic rebuilding enabled.
Rebuild Options: Rebuild Rate
A High setting assigns most of the system resources to rebuilding.
Rebuilding goes faster, restoring redundancy sooner but read/write requests
are handled slower.
A Low setting assigns most of the system resources to handling read/write
requests. Read/write requests are handled at nearly normal speed while the
rebuild takes longer.
See Rebuild an Array later in this chapter for more information on the
rebuilding process.
PCI Bus Utilization
On High setting, FastTrak holds onto the PCI bus longer for data transfers to
occur.
On Low setting, FastTrak releases the PCI bus sooner for other PCI devices
to use.
Normally, no adjustment is required. However, some video capture cards
may produce a glitch during playback of audio/video files. If this happens, try
adjusting the slider.

Initialization ― Data on all drives is set to zero, erasing the disks.
Gigabyte Boundary ― The Gigabyte Boundary feature is designed for
fault tolerant arrays (RAID 1, 0+1, 3 and 5) in which a drive has failed
and the user cannot replace the drive with the same capacity or larger.
Instead, the Gigabyte Boundary feature permits the installation of a
replacement drive that is slightly smaller (within 1 gigabyte) than the
remaining working drive (for example, an 80.5GB drive would be
rounded down to 80GB). This can be helpful in the event that a drive fails
and an exact replacement model is no longer available. Without this
feature enabled, UltraTrak will NOT permit the use of a replacement
drive that is slightly smaller than the remaining working drive.
For the Gigabyte Boundary feature to work, the Gigabyte Boundary
feature must be set to ON when the original array is created. When
enabled, the Gigabyte Boundary feature rounds the drive capacity of all
drives to the common whole GB drive size. For example, with the
Gigabyte Boundary feature enabled, the remaining working drives can
be 80.5GB and the replacement drive can be 80.3, since all are rounded
down to 80GB. This permits the smaller drive to be used. Please note
that users will lose a small amount of available storage capacity from
each drives in order to arrive at a common drive size.

Scheduled Array Synchronization
Promise uses the term synchronization to mean an automated process of
checking and correcting data and parity. It applies to RAIDs 1, 0+1, 3 and 5.
Synchronizing takes place when an array is first created and then, optionally,
on a regularly scheduled basis to maintain content integrity.

Rebuild an Array
Rebuilding is the process of restoring redundancy to a RAID 1, 0+1, 3 or 5
after one of its drives has failed. When the replacement drive has been
installed, the RAID can read and write data but there is no redundancy until
the RAID has been rebuilt, that is, the new drive receives all the data and
parity of the original.
When a drive fails for any reason, the Array goes Critical. This condition is
in Tree View. The RAID
noted when you select the Array Critical icon
alarm beeps quickly to call your attention to the condition.

to Functional condition (right).
Normally, the rebuild process begins automatically when you repair or
replace the faulty disk drive. The Array recognizes the drive and begins the
process a few moments later.
If your RAID has a hot spare, the rebuild begins without waiting for a
replacement drive. Be sure to replace the faulty drive as soon as possible.
During the Rebuild process, the array is still available to read and write data
but it may run noticeably slower.

There are two options you can specify for an Array:
Automatic Sequential / Random Access Detection
This option is only available for SuperTrak SX6000. When enabled
(checked) the read-ahead cache determines if a sequential or random
input/output event is occurring and optimizes itself accordingly. Optimizing
results in better array performance.
Enable Write Back Cache
Write back cache accepts write data from the CPU and holds it briefly in
cache memory. When the computer has idle cycles, the data is written to the
hard drive. This arrangement speeds up disk performance because you can
write data to a cache much faster than to a hard disk.
While the data is in the cache, there is a risk of loss if a power failure occurs.
Using an uninterruptible power supply virtually eliminates that risk.

Appendix
IP Address
In order for PAM to be configured over a network, you must know the IP
(network) address of every component. The Message Server uses IP
addresses to communicate with the Message Agent on the RAID PCs and
the Monitoring Utility on the network PCs.
Windows XP
To find the IP network address, go to Start > Control Panel > Network
Connections > Local Area Connection > Support tab.
Figure A-1. Local Area Connection Status dialog box and Support tab.
The IP address is the means of identification of a PC on a TCP/IP network.
In the example above, the IP address is 192.168.1.108.
73
Promise Array Manager
Earlier Windows Systems
This procedure also works on Windows XP.
To find the IP network address, go to Start > Programs > Accessories >
Command Prompt. Type IPConfig and press Enter.
Figure A-2. Use the Command Prompt to find your PC’s IP address.
Locate and record the IP addresses of all PCs and Servers on your network
that will work with PAM. This document will help you recall individual PCs
when it is time to specify their connections.

Appendix
DHCP Issues
Referring to Figure A-1 above, note that it says Address Type: Assigned by
DHCP. This means that a DHCP server gave this IP address to this PC
when the PC connected to the network. DHCP stands for Dynamic Host
Configuration Protocol and refers to software that allows a file server to
assign IP addresses to computers on the network.
DHCP is very helpful in reducing the number of IP address a company or
organization requires. The DHCP server assigns an IP address to a
computer as it logs onto the network. The IP address will remain the same
until the computer logs off or disconnects for any reason, such as a power
failure. When the computer logs on again, it will receive a different IP
address.
Because IP addresses are subject to change when a DHCP server is
involved, make it a point to maintain the RAID PC network connections at all
times. When a disconnection happens for any reason, you must find the new
IP address and enter it into the Message Server. Instructions for doing this
appear under Message Server Address Change in Chapter 5.
To avoid the problems of changing IP addresses, assign a fixed IP address.
