NOTE If any of the listed parts are missing or damaged, call the Intergraph Customer Response
Center at 1-800-633-7248.
Identifying the Operating System Disk Drives
The box containing the operating system disk drives is labeled, “This box contains disk
drives loaded with operating system software...” Each operating system drive is labeled with
the SCSI ID number. If additional cabinets are purchased, the RAID disk drives for these
cabinets will not contain the operating system software and will not be labeled.
CAUTION Do not remove the RAID disk drives from the antistatic bags until you are ready to install
them in the InterRAID cabinet.
Selecting a Location
The InterRAID cabinets can be placed side-by-side or stacked. Keep the following in mind
when selecting a location.
u
Allow six inches of space in front of the cabinet for the door to open.
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, as follows:
−
InterRAID-6 weighs approximately 38 pounds.
−
InterRAID-8, rack-mount, weighs approximately 84 pounds.
−
InterRAID-8, tower, weighs approximately 75 pounds.
−
InterRAID-12 weighs approximately 75 pounds.
Describing Common Disk Array Features
The following features are common to the InterRAID-6, InterRAID-8, and InterRAID-12
expansion solutions.
RAID Controller Board
The RAID controller board incorporates a 32-bit RISC processor to control all functions
including SCSI bus transfers, RAID processing, configuration, data striping, error recovery,
and drive building.
Smart 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
cabinet monitors its disk drives, power supplies, cooling fans and temperature and
continually reports to the LEDs and the Information Control Panel.
NOTE The InterRAID-6 cabinet does not have an Information Control Panel.
SAF-TE Cabinet Monitoring
SCSI Accessed Fault-Tolerant Enclosure (SAF-TE) is a new method to alert the user of
abnormal system conditions. SAF-TE, in addition to the Smart Cabinet monitoring
functions listed above, allows reporting to the system of the cooling fan revolutions per
minute, power supply voltages and temperature in degrees, number of insertions per slot, and
number of powerup hours.
3
Door Lock
The front door uses an integrated 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.
NOTE After inserting the key into the lock, the key can only be removed when the door is locked.
Describing Applicable Intergraph Systems
The dual-channel InterRAID-8 is available as a deskside (tower) unit, and the rack-mount
version is available as dual-channel and single-channel, depending on the system to which it
is attached.

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
Always power on the InterRAID-6 cabinet and wait for the audible beep before powering
on the system base unit.
u
If you are installing RAID disk drives that are partially loaded with the Windows NT
Server operating system, you must complete installation of the operating system before
configuring your RAID disk array. If you do not complete installation, or if you turn off
the power to the system base unit before completing the Windows NT Server 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-6 cabinet. If
you power off the cabinet first, the RAID controller board will read the drives as dead
the next time you power on the system. Refer to Chapter 5 “Using DAC InterRAID
Utilities,” or Chapter 6 “Using MegaRAID BIOS” and Chapter 7, “Using Power
Console.”
Important Soft ware Notices
u
For DTP Server systems, Intergraph installs the Microsoft Windows NT Server
operating system software and prepares it for final configuration by users.
u
For desktop and deskside systems other than the DTP Server, the disk drives are
delivered with Microsoft Windows NT Server operating system software partially
installed. You must complete Windows NT Server installation before using the system.
u
The RAID controller board has two types of write caching: write-back and writethrough. 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 recommends connection to a UPS to guard against data
loss.
u
Intergraph configures the RAID controller board to RAID level 5. RAID controllers
support RAID levels 0, 1, 5, 6 (0+1), and 7. The MegaRAID controller, in addition to

Placi ng Cabinets
To place the cabinets side-by-side:
1. Place the feet on the bottom of the cabinet as described in the Feet Installation sheet.
2. Set the cabinet a few inches away from the existing cabinets.
30
To stack the cabinets:
1. If existing InterRAID cabinets are not already stacked, remove the RAID disk drives
from them and place the drives on an antistatic surface.
CAUTION Keep track of the drive locations. You must install the drives in the same cabinets and slots
from which you remove them.
2. To rotate the Information Control Panel on the cabinet door, open the cabinet door and
remove the folded section of ribbon cable from the slit in the Mylar on the back of the
door.
3. Using a 5/16-inch nutdriver, remove the hex nuts from the corners of the Information
Control Panel.
4. Rotate the Information Control Panel one-quarter turn counterclockwise and re-attach it
to the door with the hex nuts. Do not overtighten the nuts.
5. Close the cabinet door.
6. Place the rubber pads from the accessory pack into the recessed locations on the left side
(as viewed from the front) of the cabinet.
7. Place the bottom cabinet on its rubber pads on a flat, hard surface (not on carpet).
8. For each additional InterRAID cabinet you want to stack, repeat steps 2 through 6 and
place the additional cabinet on top of the previous cabinet.
CAUTION You may stack up to four InterRAID cabinets in a single stack.
9. If you removed RAID disk drives from existing InterRAID cabinets, replace them.
Setting Up Host
The following provides instructions for setting up the host system for use with an
InterRAID-12 Expansion Solution RAID controller board.
To setup the host for use with InterRAID-12:
1. If your Expansion Solution came with a RAID controller board, install it into the
appropriate PCI slot in the system’s base unit. Refer to Chapter 1, “Getting Started,” for
PCI slot designations. Refer to your system’s documentation for instructions on opening
the base unit, taking precautions against electrostatic discharge, and installing option
boards.
−
On InterServe 6x systems, the primary RAID controller is installed in PCI slot 3.
Install additional (secondary) controllers in PCI slots 4, 5, and 6.
−
On InterServe 6xx systems, the primary RAID controller is installed in PCI slot 3.
Install additional (secondary) controllers in PCI slots 2, 1, and 6 (in that order). If
PCI slot 6 is not available, use PCI slot 5.
−
For Intergraph deskside systems with internal RAID, the internal RAID subsystem
already contains the boot disk drives. The primary RAID controller connects to the
internal RAID subsystem.
−
For Intergraph deskside systems with an internal hard disk drive, the internal hard
disk drive is the boot disk drive and does not require connection to a primary RAID
controller. Any external disk arrays and associated RAID controllers are secondary.
2. For stacked cabinets, route the RAID SCSI cables and power cables through the cable
guides on the back of each cabinet.
Installing the RAID Disk Drives
The InterRAID-12 cabinet contains up to twelve 1.0-inch high, 3.5-inch form factor RAID
disk drives. Supported capacities include 1 GB, 2 GB, 4 GB, and higher as the disk drives
become available. Contact an Intergraph sales representative for drive availability. The lefthand side of the disk drive label identifies the disk drive size.
31
NOTE Intergraph attaches a SCSI ID number to the disk drive label to identify each of the boot disk
drives. All other disk drives are for data storage and do not specify a SCSI ID number.
CAUTION Ensure you install the boot disk drives into the InterRAID-12 cabinet that connects to the
primary RAID controller board.
To install the RAID disk drives:
1. Unlock the front panel door using the key for the InterRAID-12 cabinet.
2. Remove the RAID disk drives from the carton labeled, “This box contains disk drives
loaded with operating system software ...” The first three drives (ID 0, 1, 2) contain the
operating system.
The following table shows the order in which to install the boot disk drives:
Disk Drive Label

4. Install the remaining RAID disk drives without labels into the primary cabinet. You can
install them in any order as long as the slots are filled sequentially upward (for example,
do not install drives in slots 5 and 7, leaving slot 6 empty).
If necessary, fill in the label information for each RAID disk drive. Refer to the Drive
Labeling instruction sheet. The disk drive label has blank spaces for you to apply the
appropriate numbers to indicate the RAID controller board number (ADP X), channel
number (CHN Y), and SCSI ID number (ID Z). In the table below, Intergraph reserves
SCSI ID 3 for the entire disk array. The lower six RAID disk drives connect to channel
0, and the upper six RAID disk drives connect to channel 1.
Use the following table to label the drives:
33

6. If you have additional cabinets, install the RAID disk drives and complete the drive
label information as appropriate.
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
Always power on the InterRAID-12 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-12 cabinet. If
you power off the cabinet first, the RAID controller board will read the drives as dead
the next time you power on the system. Refer to Chapter 5 “Using DAC InterRAID
Utilities,” or Chapter 6 “Using MegaRAID BIOS” and Chapter 7, “Using Power
Console.”
34
Important Soft ware Notices
u
You must complete the Windows NT Server installation before using the system.
u
The RAID controller board has two types of write caching: write-back and writethrough. 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 is interrupted. Intergraph recommends connection to a UPS to guard
against data loss.
u
Intergraph configures the RAID controller board to RAID level 5. RAID controllers
support RAID levels 0, 1, 5, 6 (0+1), and 7. The MegaRAID controller, in addition to
the other levels, also supports RAID level 3.
To power on and configure the system:
1. Power on the InterRAID-12 cabinet and wait for the audible beep.
2. Power on the system base unit and the monitor.
3. Complete the Windows NT Server installation. Refer to the system’s setup or
configuration documentation.
4. Install the proper software utilities available for the RAID controller board installed in
the system.
For DAC960P and DAC960PD boards, install the DACADM and DACMON utilities.
Refer to Chapter 5, “Using DAC InterRAID Utilities.”
For MegaRAID boards, install the MegaRAID BIOS and Power Console utilities. Refer
to Chapter 6, “Using MegaRAID BIOS” and Chapter 7, “Using Power Console.”
WARNING After you configure the RAID disk drives, it is very important that you backup the
configuration to a diskette. It will be very helpful for future use in the event the
configuration should become lost. Refer to Chapter 5 “Using DAC InterRAID Utilities,”
or Chapter 6 “Using MegaRAID BIOS” and Chapter 7, “Using Power Console.”
5. If necessary, configure the RAID controller board to your preferences. Refer to Chapter
5 “Using DAC InterRAID Utilities,” or Chapter 6 “Using MegaRAID BIOS” and
Chapter 7, “Using Power Console.”
6. 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. Refer to
the Windows NT Server System Guide for information on using Disk Administrator.
5 Using DAC InterRAID Utilities
This chapter pertains only to systems containing either the DAC960P or DAC960PD
controller. If your system contains the MegaRAID controller, refer to Chapter 6.
NOTE Chapter 1 describes how to determine which RAID controller shipped with your system.
This chapter describes how to upgrade the DAC960 driver and use the RAID Basic
Input/Output System (BIOS) and all of the DAC960 Configuration Utility (DACCF) options.
The “Common DACCF Procedures” section contains procedures such as enabling automatic
rebuild, changing the write policy, configuring additional disk arrays, and recovering
unusable (DED) disk drives.
Intergraph includes DACCF on a diskette delivered with the InterRAID cabinets. Other
available utilities include the Disk Array Controller Administrator (DACADM) and the Disk
Array Controller Monitor (DACMON).
NOTE If you need to load the new driver, follow the applicable instructions in the following section
for Windows NT 3.51 or Windows NT 4.00. The DAC960 driver resides on the same diskette

u
System Drive
Select Adapter and System Drive have their own unique dialogs, whereas the Device
Selection dialog is common for all of the other entries.
The Device Selection dialog shows a matrix of the drives connected to the various channels
of the selected RAID controller board. The left-most column of the corresponds to SCSI ID
0. The SCSI ID increments by one number for each column. The letters STBY, DEAD, and
ONLN indicate standby, dead, and online. During rebuild, a box with dashes indicates the
rebuild process is occurring. A blank box indicates that a disk drive was not found for that
channel location and SCSI ID.
NOTE SCSI ID3 is blank to indicate it is reserved for the entire disk array.
Select Adapter
Use Select Adapter to select the RAID controller board for information or to perform an
action. The available DAC960 controller boards on the system are displayed as Adapter 1,
Adapter 2, etc. in the small boxes.
Commands are executed only on the selected board. If a RAID controller board is not found,
the message “Not Installed” appears in the box.
Drive Information
Use this option to provide information about the disk drives connected to the selected RAID
controller board in a system. The horizontal bar represents the SCSI channel and the box
represents a drive. The box also indicates the drive status. Select a drive to view
information on soft error, hard error, parity error, drive model, or select OK to exit.

RAID controller board. The information displayed includes the system drive number, RAID
level, write policy size, and status. The System Drive option also indicates system drives
that are Online, Offline or in a Critical state.
40
DACMON Overview
The DACMON utility monitors the activities of the RAID controller board in the system and
records the activities in the Event Viewer. DACMON will fail to run if the RAID controller
board is not present. DACMON displays the status of the RAID controller board, the disk
drives, and the progress of any rebuild operations.
Starting DACMON
The DACMON icon must be included in Startup for activation under the Windows NT
operating system.
To create a DACMON icon:
1. Open Startup.
2. From File menu in Program Manager, select New. The dialog displays.
3. Select Program Item. The dialog displays.
4. In the Description box, type dacmon.
5. In the Command Line box, type dacmon.
6. Select OK. The dialog closes. The next time the system reboots, the minimized
DACMON icon appears in the lower left corner of the display.
To view output from the Event Viewer:
1. Under Administrative Tools, select Event Viewer.
2. At Log, select Application. The messages appear concerning the activities of the RAID
controller board and the time of the event.
RAID BIOS Setup
The RAID controller board contains its own BIOS separate from the system BIOS. Refer to
the system’s hardware documentation for information regarding the system BIOS for the
host server.
NOTE The DAC960P and DAC960PD boards use the same BIOS.
Startup Sequence
During power up, the RAID controller board’s BIOS displays a sign-on message with its
version number and date. The sign-on message looks similar to the following:
DAC960P(D) BIOS Version x.xx--
Thereafter, the BIOS tries to locate the RAID disk array controller. Once located, the BIOS
determines if the controller firmware is operational. The RAID BIOS also looks for any
initialization error message that may be posted by the controller firmware. If it finds a
message, it displays one of the following errors on the screen and aborts the installation
process.
DAC960 fatal error--memory test failed
DAC960 fatal error--command interface test failed
DAC960 hardware error--run diagnostics to pinpoint error
DAC960 firmware checksum error--reload firmware
If any of these messages displays, call the Customer Response Center at
1-800-633-7248 for assistance.
41
Error Conditions While Checking the Drives
If the firmware finds a valid DAC960 configuration, but it does not match the SCSI drives
currently installed, one or more of the following messages display:
Unidentified device found at channel x....
Device identified for chn x, tgt y found at chn x’, tgt y’
SCSI device at chn x, tgt y not responding
If any of the above messages displays, the firmware stops the initialization process, except to
find other mismatches. Then, the BIOS displays the following:
DAC960 Configuration Checksum error-run configuration utility
Mismatch between NVRAM and Flash EEPROM configuration
At the next stage the following message may appear:
Recovery from mirror race in progress
The above message displays if the firmware detects that the system powered off abruptly,
letting some incomplete write operations occur.
The following messages may also appear:
42
Adapter cannot recover from mirror race!
Some system drives are inconsistent!
If the firmware fails to respond to the BIOS inquiry within two minutes, the following
message displays:
DAC960 not responding--no drives installed.
The BIOS then inquires for the firmware version and other information, and displays the
following message:
DAC960 firmware version x.xx
One or more of the following messages display if the firmware reports the error conditions:
Warning: X system drives are offline
Warning: X system drives are critical
Warning: The following SCSI devices are dead--chn x, tgt y...
No system drives found: None installed
X system drives installed
The BIOS repeats the same process for additional DAC960 controllers present in the system.
Then, when possible, it proceeds to boot from the first system drive on the primary RAID
controller board.
Overview of DACCF
To use DACCF, you should be familiar with MS-DOS and understand the basic terminology
associated with RAID. Refer to Chapter 10 and the glossary for basic information about
RAID concepts and terminology.
The non-volatile memory and flash EEPROM on the RAID controller board stores the
DACCF configuration data. When you restart the system, the RAID controller (DAC960P
or DAC960PD) uses this information to define the RAID configuration to the operating
system.
Throughout the utility, a banner at the top of the display shows the title, version number,
date, controller name, slot number, and firmware version. At the bottom of every display,
DACCF indicates the actions you can take for each menu option. Additionally, information
boxes describe possible actions not allowed. Warning boxes display when the next action
could destroy data on the drives, erase configurations, or has other serious system
consequences.
The following table defines the terms you will see while running DACCF and configuring
drives.
RDY Disk drive ready for configuration
CDR CD-ROM drive
TAP Tape drive
UNF Unformatted drive
PAK Configured packs
DRVS Number of drives in a pack
SIZE Size of the packs (in megabytes)
ONL Drive online (part of pack)
DED Failed drive
RBD Rebuilding
WRO Rebuilding (write only)
FMT Formatting
SBY Standby drive

Starting DACCF
You must run DACCF from a diskette. The boot sequence of the system must be A:, C:. If it
is not, refer to the system’s hardware documentation for instructions to change the boot
sequence.
To start the DACCF utility:
1. Insert the DACCF diskette into the floppy disk drive, and then restart the system.
2. At the command prompt, execute DACCF by keying in daccf.
DACCF detects the drives connected to the RAID controller board. A display similar to

01. Automatic Configuration
Use the Automatic Configuration option in the DACCF Main Menu only when three to eight
disk drives of the same capacity are attached to the RAID controller; the drives can be in
different disk arrays. This function aborts after displaying an error message if the drive
capacities are different.
Automatic Configuration creates a single pack using all of the drives, and then creates a
single RAID Level 5 system drive when you select the write policy for the system drive. The
system disk drive number is 0. You can define a maximum of eight (8) system drives per
DAC960 RAID controller.
To perform automatic configuration:
1. From the DACCF Main Menu, select Automatic Configuration. If a valid configuration
exists, a warning message displays:
A valid configuration exists. Proceeding further will destroy
this configuration.
ENTER to select the
2. Select YES in the confirmation window to proceed. Select NO to return to the Main
Menu.
After selecting YES, the RAID controller examines the total capacity of each drive
connected to the controller. If all the drives are the same, this message displays:
Do you want to have Write Caching enabled?
3. Selecting YES sets the write policy to Write-back. Selecting NO sets the write policy to
Write-through. Write-through caching is required when re-installing the operating
system (the installation will fail if set to Write-back). After an installation, you can reset
it to Write-back.
CAUTION 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 during a power
failure. Without a UPS, a power failure can corrupt a disk drive resulting in lost data.

The Pak/Drvs column (top left) lists all the current arranged packs and their sizes. The size
specified for each pack is the sum of the capacity of the drives in the pack.
NOTE If the drives in a pack are not the same size, then the size of the pack is a product of the
number of drives in the pack and the smallest drive in the pack.
The Sys Drv column (lower left) lists all the created system drives, their sizes, RAID levels,
and write policies. If you have not defined a system drive, the Sys Drv column is empty.
The column updates as you define the system drives.
NOTE Drives in an arranged pack that have not been configured into a system drive will be
automatically configured as standby (SBY) drives.
The System Drive Definition menu has two options: Create System Drive and Toggle Write
Policy. The following instructions allow you to create a system drive.
DAC960 System Drive Size Limit
If your system has InterRAID disk arrays that use a DAC960P or DAC960PD RAID
controller board with version 2.x (or previous) firmware, be aware of the following
limitations:
u
You cannot create a system (logical) drive larger than 32,768 MB.
u
You can create a pack larger than 32,768 MB. However, if you do so, and then try to
create a system drive larger than 32,768 MB, the attempt to create the system drive will
fail.
WARNING If you try to create a system drive larger than 32,768 MB, the Mylex DACCF utility
program will insert your original drive size (default) and not create a system drive.
You can work around these limitations as follows:
1. Create one or more packs, with each pack containing up to eight disk drives of any size,
as required.
2. Divide each pack into system drives, with each system drive less than or equal to 32,768
MB.
3. Initialize the system drives.
53
If you require the entire amount of disk space to appear as a single system drive, rather than
as multiple 32 GB (or smaller) system drives, you can combine the smaller drives into a
logical volume using the Windows NT Disk Administrator. Combining the drives in this
way does not affect the speed or capacity of the disk subsystem.
NOTE The terms
To create a system drive:
1. You can define a maximum of eight (8) system drives per DAC960 RAID controller.
From the System Drive Definition menu, select Create System Drive. The first arranged
pack in the Pak/Drvs column highlights, and the RAID Levels display as follows.
RAID Level
RAID 0
RAID 1
RAID 5
RAID 6
RAID 7
system drive
and
logical drive
are used interchangeably.
54
The following table briefly describes the supported RAID levels.
RAID
Level
Description
0 Data is striped across several physical drives, yielding higher performance
than is possible with individual drives. This level does not provide
redundancy.
1 Drives are paired and mirrored. All data is 100 percent duplicated on an
equivalent drive.
5 Data is striped across several physical drives. For data redundancy, drives
are encoded with rotated XOR redundancy. Parity is spread across all drives.
6 (0+1) Combines RAID Level 0 and RAID Level 1
7 Drives are seen independently as with any disk controller, or spanned and
seen as a single disk. This option does not provide redundancy.
NOTE Refer to Chapter 10 for detailed information about the various RAID levels.
Valid RAID levels are determined by the number of drives in the selected pack. You
can choose valid RAID levels only for the highlighted pack.
2. Select a RAID level for the highlighted pack, and then press
ENTER. The Enter Size
window shows the maximum possible size for the system drive being defined.
NOTE The size you specify is the actual size of the system drive, which includes the overhead for
the RAID level and redundancy. The size of the system drive is what the operating system
recognizes and uses. If you do not specify the size as the total available capacity, then you
can define another system drive on the same pack. The maximum size of a system drive is
32,768 MB.
3. Enter the size for the system drive. Two windows display as shown.
System Drive# = 0
RAID Level = 5
Capacity = 3039 MB
Do you want to create
this system drive?
NO
YES
NOTE Spanning a system drive across multiple packs is automatically done when the size of the
packs are the same.
55
4. Select YES to create the system drive as defined. The system drive information displays
in the Sys Drv column.
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. If you want to change the policy to write-back for systems with a UPS
attached, refer to the instructions for changing the write policy in this section.
5. To create another system drive on a different pack, or on the unused space of the same
pack, repeat steps 1 through 4 above. If the space is insufficient on a partially defined
pack, a message explaining this condition displays when you try to define a system
drive.
6. After creating all the system drives, press
ESC twice. When the Save Configuration
window displays, select YES to save the configuration to flash EEPROM.
CAUTION If you select NO in the Save Configuration window, the currently defined configuration is
entirely discarded, and the program returns to the DACCF Main Menu.
NOTE If you press
and the program returns to the New Configuration menu. You can continue later with the
configuration process.
ESC in the Save Configuration window, the defined configuration remains intact
7. Initialize all of the new system drives. Refer to "05. Initialize System Drive" in this
chapter.
8. Ensure the Array Encl MGMT I/F option is set to Enabled to allow automatic disk drive
rebuild. Refer to “09. Advanced Functions,” in this chapter for more information about
the Array Encl MGMT I/F option and other hardware parameters.
The following instructions allow you to change the write policy for the system drives.
To change the write policy of a system drive:
1. From the System Drive Definition menu, select Toggle Write Policy. The write policy
of the first system drive highlights in the Write Mode column.
2. Press
ENTER to toggle the policy. For each system drive policy you need to change,
select the policy and press
ENTER.
3. Once you change the write policy on all the desired system drives, press
the System Drive Definition menu.
4. Press
ESC again to save the configuration.
ESC to return to

Intergraph recommends that you use the automatic rebuild feature, rather than rebuild the
replacement disks manually. Systems using a redundant RAID level without standby drives
in place pose a risk should one of the online drives suddenly fail. The disk array will
continue to function without interruption, but the RAID system cannot tolerate further
physical drive failures, since data on the drives is no longer redundant. In order to make the
system redundant, you must replace and rebuild the failed disk drive.
NOTE The Rebuild option only works in systems with redundant system drives. If you attempt to
rebuild a drive in a non-redundant system, errors will occur.
To manually rebuild a new disk drive:
1. From the DACCF Main Menu, select Rebuild. A menu similar to the following
displays. The drive marked dead (DED) indicates a replacement disk drive.

When the rebuild completes, a message displays stating that the rebuild was a success, or
that errors occurred. If errors occur, open the Bad Block Table as described in “07. Tools”
in this chapter.
05. Initialize System Drive
Once a system drive is created (refer to “02. New Configuration” for details), it must be
initialized before the system can use it. The process fills the drives with initialized data and
synchronizes redundancy (mirror or parity). Errors can result if you fail to initialize a
system drive. For example, the drive may not function properly, fail to boot, fail to install
the operating system, or fail the consistency check. Also, a change in the size of the system
drives or packs requires that you initialize a system drive.
NOTE The initialization process is much faster with write-back cache enabled. You can enable
write-back cache for this process, and then disable it after initialization, if desired. Refer to
“03. View/Update Configuration” and select Define System Drive to change the write policy.
Once the system drive initialization starts, it cannot be aborted.
To initialize a system drive:
1. From the DACCF Main Menu, select Initialize System Drive. A list of system drives
displays with the first system drive highlighted. The following message also displays:
60

<Enter> to select. After selecting the required System drive(s),
move to the ‘START’ box and hit <Enter> to proceed with the
Initialization.
!!Warning: Initialization of the System drives will destroy data
on drives.
2. Press
ENTER to select the system drive. If multiple system drives exist, press ENTER on
each for simultaneous initialization. A check mark indicates the selected system drives.
3. After selecting all the system drives to be initialized, select the Start box and then press
ENTER. The following message displays:
Do you want to proceed with initialization?
4. Select YES to initialize all of the selected system drives. A progress bar indicates each
system drive initialized.
5. When the initialization of all system drives completes, press any key to save the
configuration and return to the DACCF Main Menu.
6. Ensure the Array Encl MGMT I/F option is set to Enabled. Refer to “09. Advanced
Functions,” in this chapter for more information about the Array Encl MGMT I/F option
and other hardware parameters.
06. Consistency Check
Use the Consistency Check option in the DACCF Main Menu to verify data consistency on
redundant system drives. You should always execute a Consistency Check after a system
crash or power interruption.

1. From the DACCF Main Menu, select Consistency Check. A list of current system
drives displays.
2. Use the cursor keys to select a system drive, and press
ENTER. If the system drive you
select is not a redundant drive, the following message displays:
Cannot Check consistency of a non-redundant System drive
If the selected drive is redundant, the consistency check starts. When the consistency
check completes, a message displays the results. If inconsistent blocks were found, the
following message displays.
Do you want to restore consistency?
3. Select YES to restore consistency to the system drive.
NOTE Restoring consistency could mean loss of data in the blocks that were found inconsistent.
4. After restoring consistency, select another drive to check, or exit to the DACCF Main
Menu.

Hardware Parameters
When you select Hardware Parameters, a menu similar to the following displays. Use the
arrow keys to select a parameter, and press
ENTER to toggle the settings.
67
Hardware Par ameters
Battery Backup Disabaled
Array Enclosure Man agement Enabled
StorageWorks Fault MGMT. (TM) Disabled
NOTE The default hardware parameters are: Battery Backup = Disabled, Array Enclosure
Management. I/F (AEMI) = Enabled, StorageWorks Fault MGMTI/F = Disabled.
The InterRAID-6, InterRAID-8, and InterRAID-12 disk arrays do not support the Battery
Backup option. Intergraph recommends connection to a UPS to guard against data loss.
The Array Enclosure Management I/F option should be set to Enabled each time you create a
new configuration. This option allows the Windows NT Server operating system to
recognize a failed drive and to begin the automatic on-line rebuild of the drive. Intergraph
recommends the automatic rebuild capability for every InterRAID configuration.
The StorageWorks Fault Management option is not used by the InterRAID-6, InterRAID-8,
and InterRAID-12 disk arrays. The default is Disabled.
68
Physical Parameters
When you select Physical Parameters, a menu similar to the following displays. The three
physical parameters that can be set are Default rebuild rate, the Stripe size (K bytes), and
Controller read ahead. Use the arrow keys to select a parameter, and press
ENTER to toggle
the settings.
Physical Par ameters
Default Rebuild Rate 50
Stripe Size (K bytes) 8
Controller read ahead Enabled
NOTE The default physical parameters are: Default rebuild rate = 50, Stripe size (K bytes) = 8,
Controller read ahead = Enabled.
Use the Default rebuild rate option to change the rebuild rate from 0 to 50. A rebuild rate of
50 is the maximum. A higher value assigns a higher priority to the rebuild activity rather
than the other activities, resulting in a faster drive rebuild, but slower disk performance. If
the rebuild needs the least priority, set the rebuild rate to 0 to increase performance for other
activities.
The Stripe size (K bytes) option changes the way of accessing the information on the drives.
Stripe sizes of 8K, 16K, 32K and 64K are supported. A higher stripe size results in a higher
sequential throughput and a slightly reduced random throughput.
WARNING When you select a different stripe size, all existing data on the drives will be lost.
Back up the drives before changing the stripe size.
The Controller read ahead option, when set to Enabled, directs the controller to read the data
from the block requested and from one block ahead. This method of reading data assumes
that the subsequent block of data will soon be requested. The Controller read ahead option is
Enabled by default and will increase the performance of read operations.
SCSI Xfr Parameters
The SCSI Xfr Parameters menu allows you to change Data transfer rate and Command
tagging parameters for each channel on the current RAID controller board. When you select
the SCSI Xfr Parameters from the Edit/View Parameters menu, you are prompted to select a
channel. After selecting the channel, the following menu displays.
SCSI Xfr Paramet ers
Data transfer rate 10 MHz
Command tagging Enabled
SCSI data bus width 16 Bit
NOTE The default SCSI Xfr parameters are: Data transfer rate = 10 MHz, Command tagging =
Enabled, SCSI data bus width = 16 Bit.
The Data transfer rate option sets the default SCSI negotiation rate for the selected SCSI
channel. The options are 10 MHz, 8 MHz, 5 MHz, and Asynchronous. The default is 10
MHz for the disk drives.
The Command tagging option enables or disables command tagging support for the selected
SCSI channel. The default is set to Enabled.
The SCSI data bus width option allows you to select either 8 Bit or 16 Bit parameters.
Verify that 16 Bit is enabled.
Startup Parameters
69
The options for the Startup Parameters (Spin up option, Number of devices per spin, and
Delay) can be used to set up the way the disk drives spin initially. However, by default, the
InterRAID cabinet power supplies manage how the drives spin up, so these options do not
need changing. The disk drives spin up one at a time, with a four-second delay between spin
up. If you change the Spin up parameter to Automatic, then the Devices per spin and Delay
parameters can also be changed. The following menu shows the startup parameters.
NOTE This parameter only applies to the disk drives in the disk array, not to other SCSI devices.
Startup Para meters
Spin up option On power
Number of devices per spin 0
Delay (seconds) 0
NOTE The default startup parameters are: Spin up option = On power, Number of devices per spin
= 0, Delay (seconds) = 0.
70
10. Diagnostics
The last option in the DACCF Main Menu is for performing system level diagnostics on the
selected RAID controller. Diagnostics are reserved for Intergraph field engineer use only.
An engineer can access the diagnostics with an uppercase Y as supported under DACCF
version 3.10.
NOTE Before running the diagnostics, refer to the README file on the DACCF diskette for
limitations and warnings about the diagnostics.
Error Conditions
During startup, DACCF may report the following types of messages:
u
Installation aborted errors
u
NVRAM/Flash configuration mismatch errors
u
Controller checksum errors
The following sections describe the errors.
Installation Aborted Errors
If reporting an installation abort condition, the following message displays:
Installation aborted
The cause of this error includes a faulty SCSI cabling, SCSI channel, controller, or improper
power to the disk drives. This error also occurs if you power off the InterRAID cabinet
before the system.
To recover from an aborted installation:
1. Press any key. A list of all the disk drives displays. The state of all the drives whose
state changed since the last time the InterRAID cabinet was powered off also displays.
2. Press the
system drive and other associated information already stored.
3. Power off the system and power off the InterRAID cabinet. Then, restart the InterRAID
cabinet and the system.

S key to save the configuration.
4. Power off the system and power off the InterRAID cabinet. Then, restart the InterRAID
cabinet and the system.
Controller Checksum Errors
If a configuration checksum error is present, DACCF displays the following message,
advising the user to reset the RAID to a default configuration.
The controller configuration table has a checksum error. This may
be due to corruption in the configuration tables stored in the
controller’s FLASH memory. To overcome this problem the
configuration table has to be restored to the default values. Then
rerun the utility and restore the required configuration from a
previously backed up file using menu options under “Tools.” If
there is no backup then the controller parameters have to be set to
the required values using “Advanced Functions” option from the “Main
Menu.” Setting wrong values may cause data loss!
To recover from the controller checksum error:
1. Press the
2. Exit DACCF, power off the system and power off the InterRAID cabinet.
