1 Getting Started
This chapter provides basic information about the InterRAID-8e disk array cabinet. Read
this information before setting up the cabinet. The setup chapters for deskside and rackmount cabinets assume the system base unit is already set up.
u
To set up the deskside cabinet, see Chapter 2, “Setting Up InterRAID-8e Deskside.”
u
To set up the rack-mount cabinet, see Chapter 3, “Setting Up InterRAID-8e RackMount.”
InterRAID-8e Features
The following provides a brief description of the features of the InterRAID-8e disk array
cabinets.
Door Lock
The front door uses a door lock to prevent unauthorized access to the internal components.
Two keys are provided with the cabinet. To unlock the door, insert the key and turn it
counterclockwise. To lock the door, turn the key clockwise.
1
Cabinet Monitoring
The cabinet uses an intelligent interface (microprocessor) to alert the user in the event of an
abnormal system condition. The microprocessor resides on the SCSI bus and communicates
the level of fault-tolerance to the user through software, LEDs, and audible alarms. The
microprocessor monitors the working status of the cabinet’s disk drives, power supplies,
cooling fans and temperature, and continually reports to the LEDs and the Information
Control Panel.
The microprocessor uses the SCSI Accessed Fault-Tolerant Enclosure (SAF-TE) method to
communicate abnormal system conditions. SAF-TE provides more detailed status
information than simple working or failed status. SAF-TE allows the microprocessor to
report items such as cooling fan speed and temperature.
Information Control Panel
The Information Control Panel (ICP) has a liquid crystal display and five function keys to
allow you to monitor the power supplies, fans, microprocessor, and cabinet temperature.
You can also silence the audible alarm, view component system status, read the firmware
revision level, and establish a passcode to protect SCSI ID options.
2
Ultra SCSI Bus Termination
The Ultra SCSI bus is the pathway over which disk drive data and status signals transmit
between the MegaRAID controller and the disk array cabinet. To function properly, the bus
must be terminated at both ends. The MegaRAID controller in the host system provides
termination for one end of the bus. The I/O interface boards in the disk array cabinet
provides termination for the other end.
I/O Interface Board
The I/O interface board connects between the disk array’s bus and the MegaRAID controller
board via two 68-pin very high density (VHD) SCSI connectors. The connectors are labeled
Channel 0 and Channel 1.
Channel 0
Bus Configurations
The InterRAID-8e cabinet uses Ultra Wide SCSI cable configurations for single-bus or
dual-bus operation. Separate internal modules in the disk array cabinet define the bus
configuration.
u
The InterRAID-8e with the dual-bus module provides two separate channels for the
cabinet’s disk drive slots. The top or left cabinet slots connect to one of the channels,
and the bottom or right slots connect to the other channel.
u
The InterRAID-8e with the single-bus module provides one channel for the cabinet’s
disk drive slots.
I/O Interface
Board
Channel 1
MegaRAID Controllers
The MegaRAID controller board that resides in the system base unit incorporates a 32-bit
RISC processor. The processor controls all functions including SCSI bus transfers, RAID
processing, configuration, data striping, error recovery, and drive building.
The MegaRAID controller features either two or three Ultra SCSI chips that provide the data
channels for connecting disk array cabinets. Each chip provides one channel. The use of the
channels depends on the cabinet’s bus configuration and the system base unit.
u
Dual-bus cabinets require two of the channels to be connected (Channel 0 and 1) to the
cabinet.
u
Single-bus cabinets use only one of the channels (Channel 0).
u
Some systems feature internal RAID, which uses one or two of the channels.
Chapters 2 and 3 provide additional information about connecting cabinets to the controller.
Applicable Intergraph Systems
3
The InterRAID-8e is available in deskside or rack-mount configurations for various systems.
The deskside cabinet is available as a dual-bus only. The rack-mount version is available as

Returning Equipment to Intergraph Computer Systems
Some malfunctioning equipment cannot be repaired in the field, and you must return it to
Intergraph Computer Systems for repair. Follow the steps in the next sections to obtain a
Returned Goods Authorization (RGA) log number, complete the RGA form and shipping
label, and repackage the equipment.
4
Obtain an RGA Log Number
The RGA log number must be included with the shipment for Intergraph Computer Systems
to properly track the repair work and return the equipment.
To obtain an RGA log number:
1. Determine the serial number of the system. The serial number is located on a white bar
code identification label on the back of the base unit.
2. Call the Customer Response Center at 1-800-633-7248, and identify your call to the
operator as a Warranty Call. Give the operator the serial number of the system, and you
will be given an RGA log number.
Complete the RGA Form and Shipping Label
The RGA form must accompany all returned equipment. When the service activity has been
completed by Intergraph Computer Systems, the repaired or replaced equipment will be
shipped to the address listed on the RGA form.
To complete the RGA form and shipping label:
1. Copy the RGA form at the back of this guide.
2. Complete the form, entering the RGA log number obtained from the Customer Response
Center. Ensure that the address in the From section is the location to which you want
the equipment to be returned.
3. Pack the equipment as described in this chapter.
4. Place the RGA form in the shipping box containing the equipment.
5. Copy the repair depot shipping labels at the back of this guide.
6. Add the RGA log number to a shipping label and affix it to the shipping box containing
the equipment.
7. Ship the box containing the equipment to Intergraph Computer Systems.
NOTE Parts damaged during shipping and parts not covered by the warranty are liable for repair
charges.
Repackage Disk Drives for Separate Shipment
If you need to return only the RAID disk drives, but not the disk array cabinet, they can be
returned separately. The disk drives cannot be returned in the box that shipped with the
cabinet. They must be returned in a specially designed multi-pack box for disk drive
shipment. The Intergraph multi-pack box provides the required protection needed when
shipping the disk drives by themselves.
CAUTION Pack the RAID disk drives in the Intergraph multi-pack drive box for transportation. If the
drives are not packed into this box, they could be damaged during shipment.
If you do not have an Intergraph multi-pack box, call the Intergraph Order Desk at
1-800-543-1054.
Repackage Disk Drives and Cabinet
Use the original Intergraph packaging in which your equipment was shipped. The disk drive
box fits inside the shipping carton.
CAUTION Pack all equipment in the original boxes for transportation to avoid damage during shipment.
To repack the equipment:
1. Power down the disk array cabinet and wait for the RAID disk drives to completely stop
spinning. The disk drives could be damaged if removed while still spinning.
2. Remove all of the RAID disk drives from the cabinet. Handle the disk drives carefully
and by the edges only.
3. Place each disk drive into an antistatic bag and seal the bag.

u
Allow at least a three-inch clearance in back of the cabinet for air circulation.
u
Place the cabinet on a hard, flat surface (not on carpet).
u
Ensure the surface will support the weight of the cabinets with all RAID disk drives
installed. A fully loaded deskside cabinet weighs approximately 70 pounds.
Connect the cables to the cabinet and to the controller as described next.
Connecting the Cables
This section describes connecting the RAID SCSI cables from the MegaRAID controllers to
the disk array cabinets. Information for choosing and connecting a power cord is also
included.
NOTE Keep track of the cabinet attached to each channel of the MegaRAID controllers. The drives
in each cabinet must be labeled according to their channel and controller as described later in
this chapter.
CAUTION The deskside InterRAID-8e can use RAID SCSI cables of only 1 meter. If you attach cables
longer than 1 meter to the cabinet, the cabinet and controller will not operate reliably.
CAUTION The disk array cabinets must not be daisy-chained to each other. If you attach cables in this
manner, the cabinet and controller may not operate reliably. Intergraph Computer Systems
does not recommend daisy-chaining cabinets.
TDZ-610 and InterServe 6x5 Systems
Connect the RAID SCSI cables to the disk array cabinet and MegaRAID controller as

Installing and Labeling RAID Disk Drives
The InterRAID-8e cabinet supports up to eight 1.0-inch or 1.6-inch high, 3.5-inch form
factor RAID disk drives. Capacities include 4 GB, 9 GB, and higher as the disk drives
become available. The slots of the InterRAID-8e cabinet are numbered from 1 to 8, starting
with the bottom slot. The drive SCSI ID’s of the InterRAID-8e cabinet by default are
numbered 0, 1, 2, 4, 5, 6, 8, and 9, starting with the bottom slot. The SCSI ID if SAF-TE
card by default is 3.
CAUTION High-capacity RAID disk drives are susceptible to physical shock. Handle all disk drives
carefully and avoid unnecessary handling.
To install and label the RAID disk drives:
1. Unlock the front panel door using the key for the InterRAID-8e cabinet.
2. Remove the RAID disk drives from the drive boxes.
CAUTION Carefully insert the disk drives to avoid damaging the connector.
3. Install the RAID disk drives into the cabinet as follows.
−
Extend the drive latching clips and slide the drive into the slot.
−
Push between the latching clips until the drive connects.
−
Close the drive latching clips until they snap into place, locking the drive into the
slot.
4. Label the installed drives as described below. Use the peel-off labels from the Drive

Powering On and Configuring the System
To prevent accidental power off or on, the power switch is recessed and not accessible with
the door closed and locked. Before starting the system for the first time, read the following
important operating and software notices.
Important Operating Notices
u
In some instances, the audible alarm sounds when you power on the InterRAID-8e
cabinet. To silence the alarm, press the Menu and Enter keys on the Information
Control Panel. See Chapter 9, “InterRAID-8e Power Supply Failures,” for information
about alarm conditions.
u
Always power on the InterRAID-8e cabinet and wait for the audible beep before
powering on the system base unit.
u
If you turn off the power to the system base unit before completing the setup procedures,
you must reload the operating system. Once you power on the system base unit, do not
power off the system without completing Windows NT Server installation.
u
Always power off the system base unit before powering off the InterRAID-8e cabinet. If
you power off the cabinet first, the MegaRAID controller board will read the drives as
dead the next time you power on the system.
20
Important Software Notices
u
You must complete the Windows NT Server installation before using the system.
Intergraph Computer Systems installs the MegaRAID BIOS configuration and Power
Console utilities on your system before shipment. Power Console provides valuable
information about the InterRAID-8e disk array, and can help you pinpoint any problems
that may occur in disk array operation. Power Console installation is described in
Appendix B of this guide, and in the hardware documentation delivered with your
server.
u
Intergraph Computer Systems recommends that you add a shortcut to Power Console to
the Windows NT Startup menu (Start/Programs/Startup). See Windows NT Help for
information on adding a shortcut to a menu on the Start menu.
u
The MegaRAID controller board has two types of write caching: write-through and
write-back. Write-through caching reduces the risk of data loss in the event of a power
failure. Write-back caching improves performance, but the drawback is potential data
loss if power fails. Intergraph Computer Systems recommends connection to a UPS to
guard against data loss.
u
Intergraph Computer Systems typically configures the MegaRAID controller board to
RAID level 5. MegaRAID controllers support RAID levels 0, 1, 3, 5, 10 (0+1), 30, and
50.
To power on and configure the system:
1. Power on the InterRAID-8e cabinet and wait for the audible beep. After the power-on
self-test completes, the Drive Status and Channel Mode LEDs remain green.
NOTE The Power Status LED remains amber and the LCD screen displays Non-Redundant Power
when only one power supply is present, or if more than four drives are used with two power
supplies.
2. Power on the system base unit and the monitor.
3. Configure the MegaRAID controllers installed in the system. The System Setup
contains basic information to configure the disk array appropriate for the system. See
Chapter 5, “Using the MegaRAID BIOS Configuration Utility” in this document for
details about specific procedures.
CAUTION After you configure the RAID disk drives, it is important that you backup the configuration to a
diskette. The diskette will be helpful in the event the configuration should become lost. See
the “Saving and Restoring a Configuration” section in Chapter 5.”
Use Disk Administrator in Windows NT to partition and format the disk space not used by
the operating system. When prompted to create a Signature File, select Yes. See the
Windows NT Server System Guide for information on using Disk Administrator.

controller. The dual-bus cabinet uses two channels from the MegaRAID controller. The
following sections describe the details for connecting the cabinets.
NOTE Single-bus cabinets are not available for the StudioZ RAX systems.
CAUTION The rack-mount disk array cabinet can use RAID SCSI cables up to 2 meters. If you attach
cables longer than 2 meters to the cabinet, the cabinet and controller will not operate reliably.
Single-Bus Cabinets
Keep track of the cabinet attached to each channel of the MegaRAID controller. The drives
in each cabinet must be labeled according to their channel as described later in this chapter.
The channel usage and availability of the primary controller are as follows:
u
TDZ-612 RAX, RenderRAX, InterServe 6x5R -- These systems do not use a primary
controller.
u
InterServe 8400 -- Channels 0 and 1 are used for internal RAID section. Channels 0
and 1 are not available for connecting a cabinet.
u
InterServe 8000 -- Channels 0 and 1 are used for internal RAID section. Channels 0
and 1 are not available for connecting a cabinet.
The channels available on secondary controllers are as follows:
u
TDZ-612 RAX, RenderRAX, InterServe 6x5R -- Channels 0 and 1 are available for
connecting cabinets. Channel 2 is not available.
u
InterServe 8400, 8000 -- Channels 0 and 1 are available for connecting cabinets.
Channel 2 is available if the Channel 2 access cable is installed.
To connect RAID SCSI cables:
1. Connect the RAID SCSI cable to an available channel on the primary or secondary
MegaRAID controller. Connect the other end of the cable to the lower right connector

Keep track of the cabinet attached to each channel of the MegaRAID controller. The drives
in each cabinet must be labeled according to their channel as described later in this chapter.
The cable connections from the primary controller differ for each system as described below.
The internal RAID section uses one or two channels of the primary controller, and those
channels are not available for attaching an external cable.
u
TDZ-612 RAX, RenderRAX, InterServe 6x5R -- These systems do not use a primary
controller.
32
u
InterServe 8400 -- Channels 0 and 1 are used for internal RAID section. Channels 0
and 1 are not available for connecting RAID SCSI cables to one disk array cabinet.
u
InterServe 8000 -- Channels 0 and 1 are used for internal RAID section. Channels 0
and 1 are not available for connecting a cabinet.
The channels available on secondary controllers are as follows:
u
TDZ-612 RAX, RenderRAX, InterServe 6x5R -- Channels 0 and 1 are available for
connecting cabinets. Channel 2 is not available.
u
InterServe 8400, 8000 -- Channels 0 and 1 are available for connecting cabinets.
Channel 2 is available if the Channel 2 access cable is installed.
u
StudioZ RAX -- Channels 1 and 2 of the controller in PCI slot 4 are used for the internal
RAID section, and Channel 0 is not available. Controllers in PCI slot 5 through 7 use
Channels 0 and 1 to connect cabinets, and Channel 2 is not available.
To connect cables:
1. Connect the RAID SCSI cable Channel 0 on the primary or secondary MegaRAID
controller. Connect the other end of the cable to the Channel 0 connector on the
InterRAID-8e cabinet. Repeat for Channel 1.
2. Secure the cables using the thumb screws (finger tight only). Failure to secure the
cables properly can result in intermittent problems with the cabinet or the MegaRAID
controller.
The following figure shows connecting cables to Channel 0 and 1 of a controller.
Channel 0
Channel 1
NOTE Ensure that the 2 meter cables connect to the right side of the InterRAID cabinet. The
InterRAID-8e cabinet contains special extender circuitry that supports longer (2 meter) cable
lengths connected only on the right side of the cabinet. Do not connect 2 meter cables to the
left side of the cabinet.

3. Route the cables through the cable handler (if installed) or other retaining devices, such
as clips, cable ties, etc.
4. Choose the proper power cord for the cabinet depending on your country. See the Power
Supply Cord Selection instruction sheet included in the accessory pack.
5. Connect the power cord to the InterRAID-8e cabinet and to the facility power outlet, AC
distribution box, or uninterruptible power supply (UPS).
CAUTION If the system does not connect to a UPS, data loss can occur if there is a power failure.
Installing and Labeling RAID Disk Drives
The InterRAID-8e cabinet supports up to eight 1.0-inch or 1.6-inch high, 3.5-inch form
factor RAID disk drives. Capacities include 4 GB, 9 GB, and higher as the disk drives
become available. The slots of the InterRAID-8e cabinet are numbered from 1 to 8, starting
with the right slot.
CAUTION High-capacity RAID disk drives are susceptible to physical shock. Handle all disk drives
carefully and avoid unnecessary handling.
To install and label the RAID disk drives:
33
1. Unlock the front panel door using the key for the InterRAID-8e cabinet.
2. Remove the RAID disk drives from the drive boxes.
CAUTION Carefully insert the disk drives to avoid damaging the connector.
3. Install the RAID disk drives into the cabinet as follows.
−
Extend the drive latching clips and slide the drive into the slot.
−
Push between the latching clips until the drive connects.
−
Close the drive latching clips until they snap into place, locking the drive into the
slot.
4. Label the installed drives as described below. Use the peel-off labels from the Drive
Labeling instruction sheet and fill in the information for each drive.
The left side of the disk drive label identifies the disk drive size (in GB). The label has
blank spaces for the numbers to indicate the MegaRAID controller board (ADP),
channel (CH), and SCSI ID (ID).
34
x GB
ADP
x GB
ADP
NOTE The label sheets do not include the numbers 3 and 7 for SCSI IDs. These ID numbers are
used by the disk array and for the MegaRAID controller board.
In a single-bus InterRAID-8e cabinet, all eight RAID disk drives connect to a single
channel. Use the following table to label the drives:
Disk Drive Label
ADP X CH X ID 9 8 (left)
ADP X CH X ID 8 7
ADP X CH X ID 6 6
ADP X CH X ID 5 5
ADP X CH X ID 4 4
ADP X CH X ID 2 3
ADP X CH X ID 1 2
ADP X CH X ID 0 1 (right)
In a dual-bus InterRAID-8e cabinet, the right four RAID disk drives connect to one
channel and the left four RAID disk drives connect to another channel. The following
table shows the channel and ID numbers used for drives installed in a cabinet.

Powering On and Configuring the System
To prevent accidental power off or on, the power switch is recessed and not accessible with
the door closed and locked. Before starting the system for the first time, read the following
important operating and software notices.
Important Operating Notices
u
In some instances, the audible alarm sounds when you power on the InterRAID-8e
cabinet. To silence the alarm, press the Menu and Enter keys of the Information
Control Panel. See Chapter 9, “InterRAID-8e Power Supply Failures,” for information
about alarm conditions.
u
Always power on the InterRAID-8e cabinet and wait for the audible beep before
powering on the system base unit.
u
If you turn off the power to the system base unit before completing the setup procedures,
you must reload the operating system. Once you power on the system base unit, do not
power off the system without completing Windows NT Server installation.
u
Always power off the system base unit before powering off the InterRAID-8e cabinet. If
you power off the cabinet first, the MegaRAID controller board will read the drives as
dead the next time you power on the system.
35
Important Software Notices
u
You must complete the Windows NT Server installation before using the system.
Intergraph Computer Systems installs the MegaRAID BIOS configuration and Power
Console utilities on your system before shipment. Power Console provides valuable
information about the InterRAID-8e disk array, and can help you pinpoint any problems
that may occur in disk array operation. Power Console installation is described in
Appendix B of this guide, and in the hardware documentation delivered with your
server.
u
Intergraph Computer Systems recommends that you add a shortcut to Power Console to
the Windows NT Startup menu (Start/Programs/Startup). See Windows NT Help for
information on adding a shortcut to a menu on the Start menu.
u
The MegaRAID controller board has two types of write caching: write-through and
write-back. Write-through caching reduces the risk of data loss in the event of a power
failure. Write-back caching improves performance, but the drawback is potential data
loss if power fails. Intergraph Computer Systems recommends connection to a UPS to
guard against data loss.
u
Intergraph Computer Systems typically configures the MegaRAID controller board to
RAID level 5. MegaRAID controllers support RAID levels 0, 1, 3, 5, 10 (0+1), 30, and
50.
36
To power on and configure the system:
1. Power on the InterRAID-8e cabinet and wait for the audible beep. After the power-on
self-test completes, the Drive Status and Channel Mode LEDs remain green.
NOTE The Power Status LED remains amber and the LCD screen displays Non-Redundant Power
when only one power supply is present, or if more than four drives are used with two power
supplies.
2. Power on the system base unit and the monitor.
3. Configure the MegaRAID controllers installed in the system. The System Setup
contains basic information to configure the disk array appropriate for the system. See
Chapter 5, “Using the MegaRAID BIOS Configuration Utility” in this document for
details about specific procedures.
CAUTION After you configure the RAID disk drives, it is important that you backup the configuration to a
diskette. The diskette will be helpful in the event the configuration should become lost. See
the “Saving and Restoring a Configuration” section in Chapter 5.”
4. Use Disk Administrator in Windows NT to partition and format the disk space not used
by the operating system. When prompted to create a Signature File, select Yes. See the
Windows NT Server System Guide for information on using Disk Administrator.
4 Using the Information Control Panel
You can use the Information Control Panel (ICP) to silence the audible alarm, and monitor
the power supplies, fans, microprocessor, and cabinet temperature. Other menu functions let
you view component system status, read the firmware revision level, and establish a passcode
to protect SCSI ID options.
The liquid crystal display provides a four line by twenty character display. Of the five
function keys, two move the Menu Selector up or down. The
or returns to the main menu,
ESCAPE backs up one level or cancels an action.

indicated by OK, Missing, or Failed. If you receive a hardware error, display the ICP Main
menu and choose Hardware menu, then select Component Status and use the up or down
arrow keys to view a complete list of the components.
During normal operation, if one of the power supplies fails, a continuous alarm sounds and a
warning message displays. The message tells you that the state of the power supply system is
no longer redundant. Display the Component Status menu to determine which power supply
has failed. Identify the failed unit by the power supply LED. Replace the failed power
supply to return the system to a redundant state.
Configuration Info
This option displays the cabinet type (SAF-TE) for the InterRAID-8e cabinet, and displays
information about the current RAID firmware, including product name, slot assignment,
RAM version, ROM version, and ID (in Hex format). The SAF-TE controller executes
RAM and ROM firmware code to monitor the cabinet. The following is an example display:
PROD: InterRAID-8e SAF-TE

SCSI ID
SCSI ID displays the ID that is set for each disk drive slot. Intergraph Computer Systems
recommends that you do not change any SCSI ID settings, even though SCSI IDs 0 through
15 are available and can be changed at the SCSI ID menu. If you change a SCSI ID setting,
you must turn off power to the InterRAID-8e cabinet and wait 30 seconds before turning on
power again for those settings to take effect. Be sure to turn off the power to the system base
unit before you turn off power to the InterRAID-8e cabinet.
NOTE If you turn off the power to the InterRAID-8e cabinet and then power off the system base unit,
the RAID controller will mark offline all drives in the array.
Set Upper and Lower Slot IDs
NOTE Disk drive SCSI IDs cannot be set individually with these menu selections.
Intergraph Computer Systems recommends that you do not change the SCSI ID settings. If
necessary, you can set SCSI IDs manually for each group of slots from a pre-defined table of
IDs. The currently set IDs will display on the ICP. Refer to the following example:
0123
Lower 4 0124
4567
4568
5678
The IDs will be assigned sequentially beginning with the lowest slot in the group. Choose
“Set Lower Slot IDs” or “Set Upper Slot IDs” for the appropriate slots and press the ENTER
key.
41
Reset Default IDs
Choosing the Reset Default IDs option from the SCSI ID menu will automatically set the
SCSI IDs to IDs 0, 1, 2, and 4 for the disk drives, and ID 3 for the SAF-TE. SCSI IDs for
the drives will be the same for both SCSI bus channels.
NOTE ID 3 is normally reserved for the InterRAID-8e SAF-TE board. The SAF-TE board contains
the control and monitoring electronics for the disk array. The SAF-TE board resides in one of
the two slots located in the top bay of the InterRAID-8e cabinet. The SAF-TE board ID uses
“OB” to indicate Off Bus (off line) mode. However, if SAF-TE is off line, the LEDs and other
error reporting signals will not function properly.
Heat Threshold
NOTE The Heat Threshold value is pre-set at the factory and should not be changed unless directed
by Intergraph Computer Systems Technical Support. The default setting is 116 degrees F
(47 degrees C).
Choose this option to change the temperature value for the temperature monitoring system.
If the temperature exceeds the set value, a Temperature Threshold Exceeded message
displays in the ICP. The RAID cabinet alarm sounds continuously until the problem is
corrected.
SAF-TE Chain ID
This option is for configuring the SAF-TE board for master and slave modes when cabinets
are daisy chained. Intergraph does not recommend daisy chaining InterRAID-8e cabinets.
The default setting for SAF-TE Chain ID is None.
Change Passcode
NOTE Lock mode is disabled until a passcode is entered. To enable lock mode, enter the default
passcode.
This option allows an administrator to create or change a passcode to protect access to the
SCSI ID menu, Heat Threshold, Change Passcode, and Lock (or Unlock) features.

5 Using the MegaRAID BIOS
Configuration Utility
This chapter describes how to use the MegaRAID BIOS Configuration Utility (hereafter
referred to as MegaRAID BIOS) to configure disk arrays and logical drives. This utility is
executed instead of booting the operating system. Refer to Appendix B, “Software Updates”
for installing the MegaRAID BIOS configuration utility.
The topics in this chapter include the following:
u
Identifying controller assignments
u
Starting MegaRAID BIOS
u
Identifying Management menu options
u
Exiting MegaRAID BIOS
u
Management menu tree
u
Configuring arrays and logical drives
43
u
Rebuilding critical logical drives
u
Using a pre-loaded SCSI drive “as-is”
u
Saving and restoring a configuration
NOTE If you need to load the new driver, follow the applicable instructions in Appendix B, “Software
Updates.”
Identifying Controller Assignments
CAUTION The number assigned to the controller changes according to the number of installed
controllers. Note that MegaRAID BIOS refers to controllers as “Adapters.”
MegaRAID BIOS detects the presence of RAID controllers and assigns the controller
numbers in a unique way. The assignments also vary depending on the system boot device.
Fixed Hard Disk Drive
Intergraph systems that include a MegaRAID controller but use a fixed disk drive on a
separate controller as a boot device are covered in this section.

Ultra SCSI Choose this option to enable or disable Ultra SCSI. Default is disabled.
Format Menu
Choose Format from the Management menu to low-level format one or more physical drives.
WARNING Formatting a hard drive destroys all data on the drive.
Since most SCSI disk drives are low-level formatted at the factory, this step is usually not
necessary. You must format a disk only if one of the following applies:
u
The disk drive was not low-level formatted at the factory.
u
There are an excessive number of media errors detected on the disk drive.
You do not need to use the Format option to erase existing information on your SCSI disks,
such as a DOS partition. That information is erased when you initialize the logical drive(s).
Rebuild Menu
Choose Rebuild from the Management menu to rebuild one or more failed disk drives.
Check Consistency Menu
Choose this option from the Management menu to verify the redundancy data in logical
drives using RAID levels 1, 3, or 5.

Configuring Arrays and Logical Drives
You can configure physical arrays and logical drives with Setup using the following options:
u
Easy Configuration
u
New Configuration
u
View/Add Configuration
Each configuration method requires a different level of user input. Steps 3 through 5 below
are discussed for each configuration type. Generally, the operations proceed as follows:
1. Choose a configuration method.
2. Designate hotspares (optional).
3. Create arrays using the available physical drives.
4. Define logical drives using the space in the arrays.
5. Save the configuration information.
6. Initialize the new logical drives.
7. Formatting physical drives.
Choosing a Configuration Method
Easy Configuration
In Easy Configuration, each physical array you create is associated with exactly one logical
drive, and you can modify the following parameters:
u
RAID level
u
Stripe size
u
Cache write policy
u
Read policy
u
I/O policy
If there are already logical drives configured when you select Easy Configuration, their
configuration information is not disturbed. You can define a maximum of eight (8) logical
drives per MegaRAID controller.
Configuration
New
57
In New Configuration, you can modify the following logical drive parameters:
u
RAID level
u
Cache write policy
u
Read policy
u
I/O policy
u
Logical drive size
u
Spanning of arrays
u
FlexRAID Virtual Sizing
If you select New Configuration, the existing configuration information on the selected
controller is destroyed when the new configuration is saved.
View/Add Configuration
View/Add Configuration allows you to control the same logical drive parameters as New
Configuration without disturbing the existing configuration information.
58
Designating Drives as Hotspares
Hotspares are physical drives that are powered up with the RAID drives, and usually stay in
a standby state. If a disk drive used in a RAID logical drive fails, a hotspare will
automatically take its place and the data on the failed drive is reconstructed on the hotspare.
Hotspares can be used for level 1, 3 and 5 RAID. Each MegaRAID controller supports up to
eight hotspares. There are two methods for designating physical drives as hotspares:
u
Press F4 while creating arrays in Easy, New or View/Add Configuration mode.
u
From the Objects/Physical Drive menu, select a physical drive and press ENTER. Then,
select Make Hotspare.
When you choose any configuration option, a list of all physical devices connected to the
current controller displays, as shown below:
Press the arrow keys to highlight a disk drive that has a READY indicator and press F4 to
designate the drive as a hotspare. The indicator changes to HOTSP. The second method for
designating physical drives as hotspares is to select Objects from the Management menu, and
then select Physical Drive. A physical drive selection screen will appear. Select a disk drive
and press
ENTER to display the action menu for the drive.
Press the arrow keys to select Make Hotspare and press ENTER. The indicator for the selected
drive changes to HOTSP.
Using Easy Configuration
Follow the steps below to create arrays using Easy Configuration. In Easy Configuration,
each array is associated with exactly one logical drive. You can define a maximum of eight
(8) logical drives per MegaRAID controller.
To use Easy Configuration:
1. Choose Configure from the Management menu.
2. Choose Easy Configuration from the Configure menu. The array selection menu
displays:
59
Hot key information displays at the bottom of the screen. The hot key functions are as
follows:
F2 Display the manufacturer data and error count for the highlighted drive.
F3 Display the logical drives that have been configured so far.
F4 Designate the highlighted drive as a hotspare.
3. Press the arrow keys to highlight specific physical drives. Press the spacebar to
associate the highlighted physical drive with the current array. The indicator for the
selected drive changes from READY to ONLIN A[array number]-[drive number]. For
example, ONLIN A2-3 means disk array 2, drive 3.
Add physical drives to the current array as desired. Try to use drives of the same
capacity in a specific array. If you use drives with different capacities in an array, all
drives in the array are treated as if they have the capacity of the smallest drive in the
array.
60
The number of physical drives in a specific array determines the RAID levels that can be
implemented with the array.
RAID 0 requires one to eight physical drives per array.
RAID 1 requires exactly two physical drives per array.
RAID 3 requires three to eight physical drives per array.
RAID 5 requires three to eight physical drives per array.
4. Press
ENTER when you are finished creating the current array. The logical drive
configuration screen displays.
The window at the top of the screen shows the logical drive that is currently being
configured as well as any existing logical drives. The column headings are as follows:
LD The logical drive number
RAID The RAID level
Size The logical drive size
#Stripes The number of stripes (physical drives) in the
associated physical array
StrpSz The stripe size
Drive-State The state of the logical drive
5. Set the RAID level for the logical drive. Highlight RAID and press
ENTER. The
available RAID levels for the current logical drive are displayed. Select a RAID level
and press
ENTER to confirm.
Do not use RAID 3 for any logical drive that is to be used as a DOS volume.
6. Set the stripe size when this feature becomes available. Set cache write policy, read
policy, and I/O (cache) policy from the Advanced Menu from the bottom window of the
logical drive configuration screen.
The Advanced menu options are as follows:
61
Option
Description
Stripe Size This option sets the stripe size from 2 KB to 128 KB.
Write Policy This option sets the caching method to write-back or write-through. In
Write-back caching, the controller sends a data transfer completion
signal to the host when the controller cache has received all the data in
a transaction.
In Write-through caching, the controller sends a data transfer
completion signal to the host when the disk subsystem has received all
the data in a transaction. This is the default setting.
Write-through caching has a data security advantage over write-back
caching. Write-back caching has a performance advantage over writethrough caching.
Read Policy This option enables the SCSI read-ahead feature for the logical drive.
You can set this parameter to Normal, Read-ahead, or Adaptive.
Normal specifies that the controller does not use read-ahead for the
current logical drive.
Read-ahead specifies that the controller uses read-ahead for the current
logical drive. This is the default setting.
Adaptive specifies that the controller begins using read-ahead if the
two most recent disk accesses occurred in sequential sectors.
Cache Policy This parameter enables the controller cache during data transfers
involving the selected logical drive.
Cached I/O specifies that the controller cache is used. This is the
default setting.
Direct I/O specifies that the controller cache is not used.
7. After setting the options, press
ESC to exit the Advanced Menu.
62
8. When you finish defining the current logical drive, highlight Accept from the bottom
window of the logical drive configuration screen, and press
ENTER. The array selection
screen displays if there are any unconfigured disk drives left.
9. Repeat steps 3 through 8 to configure another array and logical drive. MegaRAID
supports up to eight logical drives per controller. If you are finished configuring logical
drives, press
ESC to exit Easy Configuration. A list of the currently configured logical
drives displays:
After you respond to the Save prompt, you will return to the Configure menu.
10. Initialize the logical drives you have just configured as discussed later in this chapter.
Using New Configuration
Follow the steps below to create arrays using New Configuration. The New Configuration
option allows you to associate logical drives with partial and/or multiple physical arrays (the
latter is called spanning of arrays). To use the spanning feature and keep the existing
configuration, use View/Add/Delete Configuration.
Choosing the New Configuration option erases the existing configuration information on the
selected controller.
To use New Configuration:
1. Choose Configure from the Management menu.
2. Choose New Configuration from the Configure menu. An array selection menu shows
the devices connected to the current controller.
Hot key information appears at the bottom of the screen. The hot key functions are as
follows:
F2 Display the manufacturer data and error count for the highlighted drive.
F3 Display the logical drives that have been configured.
F4 Designate the highlighted drive as a hotspare .
F10 Display the logical drive configuration screen.
3. Press the arrow keys to highlight specific physical drives. Press the spacebar to
associate the highlighted physical drive with the current array. The indicator for the
selected drive changes from READY to ONLIN A[array number]-[drive number]. For
example, ONLIN A2-3 means disk array 2, drive 3.
63
Add physical drives to the current array as desired. Try to use drives of the same
capacity in a specific array. If you use drives with different capacities in an array, all the
drives in the array are treated as if they have the capacity of the smallest drive in the
array.
The number of physical drives in a specific array determines the RAID levels that can be
implemented with the array.
RAID 0 requires one to eight physical drives per array.
RAID 1 requires exactly two physical drives per array.
RAID 3 requires three to eight physical drives per array.
RAID 5 requires three to eight physical drives per array.
4. Press
ENTER when you finish creating the current array. To continue defining arrays,
repeat step 3. To begin logical drive configuration, go to step 5.
5. Press
F10 to configure logical drives. The logical drive configuration screen displays as
shown:
64
The window at the top of the screen shows the logical drive that is currently being
configured as well as any existing logical drives. The column headings are as follows:
LD The logical drive number
RAID The RAID level

press
Do not use RAID 3 for any logical drive to be used as a DOS volume.
7. Set the spanning mode for the current logical drive. Highlight Span from the bottom
window of the logical drive configuration screen, and press
ENTER. The choices are as
follows:
CanSpan Array spanning is enabled for the current logical drive. The logical drive can
occupy space in more than one array.
NoSpan Array spanning is disabled for the current logical drive. The logical drive can
occupy space in only one array.
For two arrays to be spannable, they must have the same stripe width (they must contain
the same number of physical drives) and must be consecutively numbered. If Array 2
contains four disk drives, it can be spanned only with Array 1 and/or Array 3, and only
if Arrays 1 and 3 also contain four disk drives. If the two criteria for spanning are met,
MegaRAID automatically allows spanning. If the criteria are not met, the Span setting
makes no difference for the current logical drive. Highlight a spanning option and press
ENTER.
65
The spanning options are:
Configuring RAID 10, RAID 30, or RAID 50 Logical Drives.
Configure RAID 10 by spanning two to four contiguous arrays, each containing one
RAID 1 logical drive. The RAID 1 logical drives must have the same stripe size. For
example, you can use the span option to configure up to four pairs of RAID 1 drives. Up
to eight physical drives can appear as one large RAID 1 logical drive.
Configure RAID 30 by spanning two to four contiguous arrays, each containing one
RAID 3 logical drive. The RAID 3 logical drives must have the same stripe size.
Configure RAID 50 by spanning two to four contiguous arrays, each containing one
RAID 5 logical drives. The RAID 5 logical drives must have the same stripe size.
8. Set the logical drive size. Move the cursor to Size from the bottom of the logical drive
configuration screen, and press
ENTER.
By default, the logical drive size is set to all available space in the array(s) being
associated with the current logical drive, thus accounting for the Span setting and for
partially used array space. For example, if the previous logical drive used only a part of
the space in an array, the current logical drive size is set to the remaining space by
default.
9. Select Advanced from the bottom window of the logical drive configuration screen to set
the remaining options.
NOTE For a description of the options, refer to the table in “Using Easy Configuration.”
10. After setting the options, press ESC to exit the Advanced Menu.

Rebuilding Critical Logical Drives
NOTE Logical drives are sometimes referred to as “a pack.”
If a disk drive fails in an array that is configured as a RAID 1, 3, or 5 logical drive, you can
reconstruct the data that was on the failed drive by first replacing the drive. You can then
rebuild the logical drive.
The rebuild types are as follows:
73
Type
Automatic
Rebuild
Description
MegaRAID automatically tries to use hotspares to rebuild failed disk
drives. Display the Objects menu, Physical Drive option screen while a
rebuild is in progress. The drive indicator for the hotspare disk drive
changes to REBLD A[array number]-[drive number], indicating the disk
drive to be replaced.

ESC to return to the
Management menu.
Using a Pre-loaded SCSI Drive “As-is”
CAUTION To use a pre-loaded drive in the manner described here, you must make it the first logical
drive defined (for example: LD1) on the controller to which it is connected.
You may have a SCSI disk drive that is already loaded with software. The drive may be a
boot disk containing an operating system. You can use the MegaRAID controller as a SCSI
adapter for such a drive by performing the following steps.
To use a pre-loaded SCSI drive:
1. Connect the SCSI drive to one of the channels on the MegaRAID controller, with proper
termination and target ID settings.
2. Boot the system and start Setup by pressing
3. Choose Easy Configuration from the Configure menu.
4. Press the cursor keys to highlight the pre-loaded drive.
CTRL+M.
5. Press the spacebar. The pre-loaded drive should now become an array element.
6. Press
ENTER. You have now declared the pre-loaded drive as a one-disk array. Display
the logical drive configuration screen.
7. Set the read policy and cache policy option on the Advanced menu.
8. Exit the Advanced menu. Highlight Accept and press
9. Press
ESC and choose Yes at the Save prompt.
ENTER.
10. Exit Setup and reboot.
Set the host system to boot from SCSI, if such a setting is available.
Saving and Restoring a Configuration
The MegaRAID configuration manager allows you to save the MegaRAID controller’s drive
configurations to a diskette. You should always back up the hardware configuration for
every InterRAID cabinet connected to the system. This section also describes how to restore
a lost hardware configuration to the MegaRAID controller.
Save Configuration to Diskette
To save a configuration to diskette:
1. Ensure the boot sequence for the system is A:, C:.
2. Insert the bootable MegaRAID diskette containing confmgr.exe into the floppy disk
drive.
3. Restart the system. Key in confmgr at the command prompt. The MegaRAID PCI
Adapter Configuration Manager displays:
MegaRAID PCI Adapter Configuration Manager Ver x.xx [July 8 1996].
Adapter 1 found at Base port = 0xec10 Irq= 0xb
75
Save Config to File 1 Restore Config from File 2
Display Adapter Config 3 Display File Config 4
Exit 5
Enter Option -
4. To save the configuration, key in 1 and follow the instructions on the screen. Use a file
name with fewer than twenty characters including the .MEG extension. The following
displays:
Saving configuration...
Press Any Key to Continue.
5. Choose another option, or press 5 to exit.
Restore Configuration to MegaRAID Controller
The MegaRAID configuration manager also allows you to restore to the MegaRAID
controller board a configuration that was corrupted or otherwise lost. The restored
configuration file must match the hardware configuration. MegaRAID assumes the number
of physical drives installed in the InterRAID cabinet is the same as the number of drives
configured in the configuration file.
76
To restore a configuration to the MegaRAID controller:
1. At the MegaRAID PCI Adapter Configuration Manager menu, key in 2.
CAUTION In the next step, key in only a MegaRAID configuration file. Restoring any other file will
overwrite the binary code for setting the registers, causing damage to the RAID controller
board. The board must be replaced.
2. Key in the filename for the configuration file at the prompt. Do not include directory
paths. If you used a .MEG extension as part of the filename, include the extension. The
configuration is read from the file and saved on the RAID controller board.
3. Press 5 to exit the configuration manager.
4. Remove the MegaRAID diskette and restart the system.
6 Using the Power Console GUI
This chapter describes how to use MegaRAID Power Console. Power Console is an object-
oriented graphics user’s interface (GUI) used to configure and monitor RAID systems
locally. Intergraph Computer Systems includes Power Console on the MegaRAID diskette
delivered with the InterRAID cabinets.
NOTE If you need to reload the MegaRAID driver, follow the instructions in Appendix B “Software
Updates.”
Power Console allows you to control and monitor the status of hard disk drives and the
RAID enclosure. You should understand basic terminology associated with RAID. Refer to
Chapter 8 and the glossary for information on RAID concepts and terminology. The topics
in this chapter include:
u
Identifying Controller Assignments
u
Starting Power Console
u
Identifying Power Console Options
u
Performing Power Console Tasks
77
u
Securing Power Console
Identifying Controller Assignments
If you have more than one MegaRAID controller (referred to as “Adapter” in Power
Console) in a host system, be sure to configure at least one logical drive on every MegaRAID
controller in the host system before you access the controllers from Power Console.
NOTE You can also set up the logical drives as discussed in Chapter 5 using the MegaRAID BIOS
Configuration utility.
Power Console detects the presence of MegaRAID controllers and assigns the controller
numbers in a unique way. The assignments also vary depending on the system’s boot device.
Fixed Hard Disk Drive
Intergraph systems that include a MegaRAID controller but use a fixed disk drive on a
separate controller as a boot device are covered in this section.
78
The following tables show how Power Console lists from one to five installed controllers.

InterServe 615, 625, 635, 645 Systems
InterServe 615, 625, 635, 645 systems are shipped from Intergraph Computer Systems with
RAID controllers installed in PCI slots 1 through 5 which should remain in these slots. On a
system with multiple RAID controllers, always use the RAID controller in PCI slot 1 as the
boot controller. On a system with one RAID controller, the controller resides in PCI slot 1.
The following tables show how Power Console lists the installed controllers.

NOTE The toolbox provides convenient access to the features. In lieu of the toolbox you can select
the same features using the top menu bar. Chapter 7 describes the options of the top menu
bar.
The following table defines some terms you will see while configuring drives and running
Power Console.
READY Disk drive ready for configuration
OPTIMAL Disk drive ready for use
ONLINE Disk drive ready for use
REBUILD Disk drive to be replaced
OFFLINE Unformatted drive
PACK Configured pack
DRIVES Number of drives in a pack
SIZE Size of the packs (in megabytes)
HOTSP Disk drive configured as hot spare (standby) drive
EMPTY No disk drive installed
DEGRADED A logical drive has encountered a problem
FAIL A disk drive has failed

Identifying Power Console Options
Power Console executes from any workstation and runs under Microsoft Windows NT. The
topics discussed in this section include:
u
Configuration Icons
u
Drag and Drop Icons
u
Logical Drives Icons and Logical Drive x menu
u
Channels Icons and Channel x menu
Configuration Icons
The icons are described below.
Display configuration; click on this icon to display the current RAID system
configuration. For example:
Print; click on this icon to make a hardcopy of the current configuration.
Auto configuration; click on this icon to allow MegaRAID to configure the
RAID subsystem.
Custom configuration; click on this icon to allow you to configure the RAID
subsystem.
Reset; click on this icon to clear the RAID configuration on the
currently selected controller. A confirmation dialog appears as follows:
Click on OK to reset the configuration or Cancel to abort the process.
83
View log; click here to display a list of MegaRAID activities.
Rebuild rate; click on this icon to set the RAID rebuild drive rate.
Rescan; when you click on this icon, the currently selected MegaRAID
controller rescans its SCSI channels to ensure drive configuration information is current.
Drag and Drop Icons
The icons are described below.
Rebuild disk; drag the physical drive icon that represents the drive to be rebuilt
to this icon to rebuild the selected drive.
84
Initialize logical drive; drag the logical drive icon that represents the drive to
be initialized to this icon.
CAUTION If you reset your configuration by mistake, you can recover it by reconfiguring the physical
drives into the same array and logical drive structure they were in, or by saving the
configuration without initializing. Another method is to save the configuration to a floppy.
Logical drive parity check; drag the logical drive icon to this icon to check
parity.
CAUTION Any parity inconsistency will automatically be corrected. This could cause loss or corruption
of data.
Trash; drag the drive icon that represents the drive to be deleted to this icon,
and then drop it.
Logical Drives Icons and Logical Drive x Menu
The following are the logical drives icons:
Status
The indictor light on each logical drive icon indicates its status.
u
Green indicates normal operation.
u
Yellow indicates that the drive performance is degraded.
u
Red indicates a failed drive.
With the cursor placed over one of the device icons, click the right mouse button to display
the Logical Drive x menu. The menu has a list of actions that can be applied to the selected
device. Refer to the following figure:
Logical Drive x Menu
You can perform RAID tasks on preconfigured RAID logical drives without halting system
operations. You can select any bolded option from the Logical Drive x pull down menu as
shown in the following dialog:
85
Change Config and
Add Drive Options
Trash Icon
Change Config and Add Drive options extend from the Advanced Menu. For more details
on these options, refer to “Creating an Array” in this chapter.
NOTE The trash can icon in the lower right corner of the MegaRAID Power Console dialog is
available for you to use. For example, to delete a physical drive from a RAID logical drive,
drag and drop a physical drive over the trash can icon.
86
Channels Icons and Channel x Menu
The channels icons consist of a stack of drive icons where each device on a SCSI channel is
represented by a disk, CD-ROM, or tape drive icon. The channel indicator light on each
channel icon indicates the status of that channel.
u
Green indicates normal operation.
u
Yellow indicates that the drive performance is degraded.
u
Red indicates a failed drive.
With the cursor over a configured device, click the right mouse button to display the Channel
x pull down menu. The menu lists the bolded options available for that physical device.
Pull Down Menu
for Channel
x
The Deactivate option lasts for 60 seconds when invoked. During this period, the RAID
controller ceases to issue commands on the SCSI bus for a selected channel. By idling the
bus activity in this manner, it assures data integrity when hot swapping disk drives.
CAUTION After a drive fails, do not place the drive back ONLINE or you will get data errors. You
should investigate why the device went offline and correct the problem.
