1.1

Site Preparation

Before installing the enclosure, make sure that adequate space is available in front of the enclosure for opening the front door (19 inches clearance) and around the enclosure for adequate airflow. See Figure 1–1 for specific space requirements.

Figure 1–1 Minimum Installation Clearance Measurements

EK–SMRAC–IG. C01 1–1


1.2

Unpacking the RAID Array 410 (SWXRA-Yx)

The RAID Array 410 is packed in a corrugated carton attached to a wooden shipping pallet, as shown in Figure 1–2A. Unpack the unit as follows:

NOTE

Before unpacking the equipment, inspect the shipping carton for signs of external damage. Report any damage to the local carrier and to your sales representative.

1. Remove the shipping straps (Figure 1–2A).

2. Remove the top cover (Figure 1–2B).

3. Remove the ramp from the top of the shipping carton (Figure 1–2B) and set it aside for subsequent use in moving the RAID Array 410 off the pallet.

4. Remove the two foam cushions from the top of the RAID Array 410 container

(Figure 1–2B).

5. Remove the sealed cardboard box packed beside the subsystem unit. It contains a cable and documentation.

6. Remove the cardboard carton surrounding the RAID Array 410 (Figure 1–2B).

7. Remove the plastic barrier bag (Figure 1–2C).

8. Once the RAID Array 410 is exposed (Figure 1–2D), examine the equipment for any apparent damage. Report any such problems immediately to your sales representative.

1.3

Removing the RAID Array 410 from the Pallet

Use the following procedure to remove the RAID Array 410 from the shipping pallet:

WARNING

Serious personnel injury can result if correct safety precautions are not taken during the removal procedure.

We recommend that three people perform the task of unloading the RAID Array 410 Array from its shipping pallet. Failure to use sufficient personnel can result in personnel injury and equipment damage.

CAUTION

Do not drop the RAID Array 410 array from a height of more than two inches, as serious structural damage to the enclosure can result.

1. Attach the ramp to the shipping pallet by fitting the lip of the ramp into the groove on the pallet, as shown in Figure 1–3.

2. Lift the lock lever on each front caster to its up position so that the RAID Array 410 enclosure can be moved.

1–2 EK–SMRAC–IG. C01

Figure 1–3 Installation of Ramp on Shipping Pallet



3. Grasping the sheet metal base assembly, carefully lift the rear of the RAID Array 410 enclosure over the “hump” in the center of the pallet and then roll the RAID Array 410 enclosure off the pallet and down the ramp to the floor. If any further lifting of the RAID

Array 410 is required, grasp the sheet metal base assembly on the side and lift it carefully.

4. Retain the shipping container and all packing materials.

1.4

Placing the RAID Array 410 Enclosure

Use the following procedure to move the enclosure to its designated site:

WARNING

To prevent damage to the RAID Array and injury to personnel, make sure to provide a clear path for the casters.

1. Roll the enclosure to the desired location.

2. If required, engage the lock on each front caster to prevent the enclosure from moving.

1.5

Installing the SWXRC-04 Controller and Write-Back Cache Module

Unlock the enclosure, if necessary, using the keys provided. If the SWXRC-04 RAID Array controller and the write-back cache module have not been installed in your StorageWorks enclosure, you should install them at this time. Do so by referring to Chapter 3, Installing

the Storage Subsystem, in the SWXRC RAID Array Controller User’s Guide

(EK-SMCS1-UG), included with the subsystem.

If your system is to be configured for dual-redundant controller operation, install the second controller and associated components at this time . Refer to Chapter 3, Installing the Storage

Subsystem, in the SWXRC RAID Array Controller User’s Guide (EK-SMCS1-UG).

NOTE

Review the information contained in any Release Notes included with the system. The Release Notes contain version-specific information, including controller configuration notes. Retain the Release Notes for future reference.

1.6

Installing the PC (Program) Card in the Controller

CAUTIONS

Follow these precautions and PC (program) card handling guidelines when installing or replacing the card. Install the (PC) program card in the SWXRC-04 RAID controller after the controller has been installed in a properly grounded SWXSC-AA cabinet. Otherwise, damage to the card may result.

The PC (program) card electrostatic discharge (ESD) shield must remain installed over the card during controller operation to protect it from electrostatic discharge that may cause the contents of the card to be damaged.



Follow these electrostatic discharge (ESD) precautions when handling the PC (program) card.

• Keep the PC (program) card in its original carrying case unless installing it.

• Do not twist or bend the card.

• Do not touch the contacts.

• Keep out of direct sunlight.

• DO NOT immerse the card in water or chemicals.

• Always push the eject button to remove the card (see Figure 1–4).

• A properly worn and attached ESD strap is required for installation and removal of the card.

1.6.1 PC (Program) Card Handling Precautions

• Obtain and attach an ESD wrist strap to your wrist. Make sure the strap fits snugly on your wrist.

• Plug (or clip) the other end to your cabinet's grounding stud (or other chassis grounding point).

• Remain grounded while working with the PC (program) card.

• Remove the ESD connection from the cabinet ground stud or other chassis grounding point.

• Remove the ESD wrist strap from your wrist.

1.6.2 Installing PC (Program) Card in Controller

Refer to Figure 1–4 for the location of the PC (program) card slot, the eject button, and the

Operator Control Panel (OCP) LEDs on the controller.

For clarity, the ESD shield is not shown in the illustration. The ESD shield attaches to the controller and covers the exposed edge of the PC (program) card and the PC (program) card eject button.

Use the following procedure to install the PC (program) card:

1. Unsnap and remove the ESD shield covering the PC (program) card opening. The ESD shield covers the card opening and the card eject button. The ESD shield is secured to the controller with two “push/pull” fasteners. To remove the ESD shield, gently pull both fastener shafts outward, approximately one-eighth inch and remove the ESD shield.

2. While holding the controller RESET depressed, insert the PC (program) card (label side up). The card eject button extends when the card is fully inserted.

NOTE

Keep the RESET button depressed while inserting the card to minimize the possibility of transients damaging the card contents and also to ensure that the controller reinitializes when the button is released.



3. Replace the ESD shield over the PC (program) card. To do so, first ensure the ESD shield fastener shafts are extended outward, away from the contact surface of the ESD shield. Place the ESD shield over the PC card and eject button and insert the ESD shield fastener clasps in their mounting holes on the controller chassis. Then, gently push the fastener shafts inward, approximately one-eighth inch, to engage the fastener clasps.

Figure 1–4 PC (Program) Card Slot Location

1.7

Connecting the Controller to Computer

Follow the steps below to connect the RAID Array 410 controller to a communications

(serial) port on your Intel-based system.

1. Locate the connecting cable that came with the RAID subsystem. It has an RJ12 connector (similar to some telephone plugs) on one end and a 9-pin serial connector on the other end.

2. Plug the RJ12 connector into the maintenance port on the RAID Array 410 controller

(see Figure 1–4).

3. Plug the serial connector into an available 9-pin serial port on your Intel-based system. If your system does not have a 9-pin serial port, use the 9-pin to 25-pin adapter supplied with your StorageWorks RAID Array 410 Subsystem. Note which serial port you use, because you will need that information when using the RAID 410 Manager program to set the communications parameters.

1.8

Installing Additional Disk SBBs in the StorageWorks Enclosure

You may install additional disk SBBs in the StorageWorks enclosure at this time. To improve performance and reliability, we recommend that you install additional SBBs in the

StorageWorks enclosure from left to right, bottom to top (as viewed facing the front of the enclosure). Doing so improves reliability by permitting you to create RAIDsets that span more than one controller channel. Also, because more than one channel (bus) is being used, throughput is improved.



To install an SBB, hold it in both hands, insert it into the guide slots, and firmly push it into the shelf until the mounting tabs snap in place. Installing the SBBs in this sequence distributes the SBBs among the SCSI ports of the RAID Array 410. Figure 1–5 shows a layout of the SCSI bus ports and corresponding SCSI ID assignments in the enclosure. Refer to

Chapter 3, Configuration Rules and Restrictions, in the SWXSC-AA Office Expansion RAID

Enclosure User Guide (EK-SMCPD-UG), included with your system.

Figure 1 –5 StorageWorks SCSI Bus Port and SCSI ID Assignment

1.9

Charging the RAID Array Controller Write-back Cache Batteries

The Write-back Cache Module contains batteries that may have discharged since the time the controller was factory-installed. If you place the controller into operation and attempt to initiate RAID commands when the battery charge is low, performance may be degraded. For more information on this subject, refer to the manual, SWXRC RAID Array Controller User’s

Guide (EK-SMCS1-UG).

We recommend that you wait until the batteries are fully charged before placing the RAID

Array into operation.

We suggest you take this opportunity now to recharge the batteries. This is accomplished by doing the following:

1. Install the power cable by routing the power cable through the cable access holes at the bottom of the enclosure. Connect the female end of the power cable to the StorageWorks enclosure’s AC Power Entry Controller, located in the lower portion of the enclosure (see

Figure 1–6).

2. Connect the other end of the power cable into a 110/220 VAC line voltage source (the power supply automatically senses the voltage level and will work with either voltage).



3. Apply power to the controller, by using the power switch on the AC Power Entry Controller. You should hear a momentary audible tone (beep), and see the indicator LEDs illuminate. In addition, the controller reset button (see Figure 1–4) contains a green LED, which should flash at approximately 1 Hz. For additional information, refer to the SWXRC RAID

Array Controller User’s Guide (EK-SMCS1-UG) and the SWXSC-AA Office Expansion

RAID Enclosure User’s Guide (EK-SMCPD-UG), included with these systems.

Power on the RAID Controller. The batteries should be fully recharged within six hours.

NOTE

As an alternative to waiting six hours, you may proceed now with the installation and getting started steps described in subsequent chapters of this manual. Then, when you perform the steps described in Chapter 4, Installing and Using the RAID Array 410

Manager for Windows NT, you will be able to check the status of the batteries. This is described in Section 4.4, Setting Controller

Communications. If the battery status shows “good,” you may then continue, and create your configuration.

To protect the board from static discharge, always use proper ESD procedures. In addition, do not remove the board from its antistatic protective cover until you are ready to install the adapter.

Install the host adapter by performing the following steps:

1. Shut down your operating system.

2. When the system has halted, power down the host computer and all attached peripherals.

Disconnect power cables from the host computer.

WARNING

Failure to remove power from the host computer and peripherals can introduce a personal hazard, or can result in damage to the host computer or loss of stored data.

2. Open the computer to gain access to the motherboard, and locate an appropriate available slot to install the adapter. Refer to your computer system manual for assistance in how to gain access to the mother board and for identifying the appropriate slot in which to install the adapter. Refer to your host adapter user manual for any guidelines or restrictions regarding slot selection for the adapter.

2.1.2

Installing the Host Adapter

The following steps must be performed to successfully install the host adapter:

1. Install the host adapter board in your computer; the board connector is held in place with the screw you removed from the blank panel. Ensure that the board end plate metal tab aligns in the computer chassis opening properly; otherwise the adapter will not seat properly.

2. Replace your host computer covers; refer to your host computer manual for additional information, if necessary.


Chapter 2. Host Adapter Installation – Intel-Based System

Connect the SCSI cable to the host adapter as shown in Figure 3–1.

3. The adapter is now physically installed. Later in the installation process, you will power on your system and load the appropriate software for the required host adapter drivers.

Figure 2–1 Connecting SCSI Cable

2.2

Installing the Subsystem

1. Unlock the RAID Array Enclosure, if necessary, using the keys provided, and open the enclosure front door.

2. Turn off AC power to the enclosure.

3. Install the SCSI cable between the host system and the RAID Controller.

•

Route the right angle connector end of the cable under the SWXRA-Yx Subsystem enclosure and up through the front access hole closest to the connector on the RAID controller.

•

Install the connector with the cable dressed to the right by firmly pushing it onto the mating connector on the controller’s trilink connector. For a single controller configuration (see Figure 3–2), the other side of the trilink contains a terminator. For dual controller configurations, one trilink contains a terminator and is connected to the trilink on the other controller (see Figure 3–3) through an interconnecting SCSI cable

(BN21L-0B).



Secure the SCSI cable to the trilink on the controller by tightening the two screws on the cable connector.

Figure 2–2 SCSI Cable Connection to Controller (Single Controller)

Figure 2–3 SCSI Cable Connection to Controller (Dual Controller)



4. Connect the power cable to the storage enclosure if it has not yet been installed. Do so by connecting the female end of the power cable to the RAID Controller power controller located at the lower right front corner of the array. Plug the power cable into a 110/220

VAC line voltage source (the power supply automatically senses the voltage level and will work with either voltage).

5. If you have not already applied power to the RAID Controller for up to 6 hours, as described in Chapter One of this manual, do so at this time. Doing so will recharge the write-back cache batteries that may have discharged since the time they were factoryinstalled. The batteries should be fully recharged in the time specified. If you attempt to initiate any RAID commands when the batteries are not charged, performance may be degraded.

NOTE

We recommend that you wait until the batteries are fully charged before placing the RAID Array into operation. If you place the controller into operation and attempt to initiate RAID commands when the battery charge is low, performance may be degraded. For more information, refer to Chapter 1, Unpacking and Setting Up

Your RAID Array 410 Subsystem Components, in this guide.

2.3

Configuration Utilities

Some PCI- or EISA-system environments may require that you run configuration utilities after installing the adapter. Be sure to consult your system documentation to verify if your

EISA- or PCI-based system requires you to run such configuration utilities (e.g., EISA configuration utility).

If such utilities need to be run, follow the instructions described in your system documentation.

Adapter-specific software that is required during this process is included in your adapter package. Utilize only the adapters and software supplied with the Windows NT platform kit as these are tested and certified to function with the SWXRC-04 RAID Controller.

2.4

Loading the Adapter Driver for Use with Windows NT

The software drivers used by Windows NT for the adapter can be loaded in one of two ways, depending upon whether Windows NT is already loaded on your system. If Windows NT is not install, perform paragraph 2.4.1 followed by 2.4.2. If Windows NT is already installed, perform only paragraph 2.4.2. It is important that the software drivers supplied with the platform kit are used in the final installation of the adapter.

2.4.1

Windows NT Not Installed on System

If Windows NT was not present on the system when the adapter was installed, you should load Windows NT at this time. As part of its installation sequence, Windows NT will automatically determine that the adapter has been physically installed in the system. Windows

NT will then automatically load the appropriate Adaptec adapter driver from the Windows

NT CDROM.



After Windows NT is installed, replace the device driver and install the device driver with the one on the enclosed Windows NT disk.

2.4.2

Windows NT Previously Installed

If Windows NT was already present on the system when the adapter was installed, you need to load the appropriate Adaptec adapter driver at this time. The Adaptec driver is contained on the Adaptec Windows NT diskette.

To install the drivers, follows these steps:

1. Log into the Windows NT system with Administrator privileges.

2. Click on the Windows NT Setup icon in the main program group.

Options menu in the Windows NT Setup window.

Add/Remove SCSI Adapter function.

5. Click on the Add button in the dialog box.

6. A warning message is displayed; click on the OK button in the Confirm box.

7. From the list of adapters on the display, scroll to the end of the list, and select Other .

You may have to click on the list to reveal all of the options including the "Other" option. The Insert Disk window appears.

8. Insert the Adaptec Family Manager set diskette for Windows NT into your system's floppy drive.

9. Type, for example: A:\winnt\3_5 and Click OK. Windows NT Setup momentarily displays a window and then displays the Select OEM Option window.

10. Click OK to select the driver entry displayed in the Select OEM Option window. The

Select SCSI Adapter Option window appears.

11. Click Install to add the selected driver displayed in the Select SCSI Adapter Option window. The SCSI Adapter Setup Window appears.

12. Click Close to close the SCSI Adapter Setup Window.

13. Restart your system for the new driver to take effect.

2.5

Installing the RAID 300, 400 Series WNT Device Driver (HSZDISK.SYS Driver)

Locate the diskette labeled RAID 300, 400 Series WNT Intel Drivers. It contains the

HSZDISK.SYS driver.

Install the HSZDISK.SYS driver by performing the following steps:

2. From Windows NT, click on command prompt in the Main program group.

3. Type the drive letter corresponding to your floppy drive (e.g., A: ).

4. Change to the i386 sub-directory by typing the following command: CD \i386

5. Type the following command:



where:

“ drive_letter ” and “ NT_root_directory ” correspond to the root path of your

Windows NT system files on your system (e.g., hszinstl c:\winnt35 ).

6. The installation process copies the driver into the correct subdirectory and creates the necessary Registry entries.

2.6

Verifying the System Recognizes the Host Adapter

Part of your computer’s start-up sequence (self-test and sizing checks) includes identifying and displaying the names of the adapters installed in your system. The displays are in the form of momentary screen displays during the start up sequence. You may utilize these momentary screen displays to verify that the system recognizes the installed adapter.

The device driver is now installed. Reboot your system now to load the driver.

Although it is not a necessary step in the Getting Started process, you may want to restart your computer at this time and verify that the system recognizes the installed adapter.

Congratulations!

You may now proceed to "Installing and Using the RAID Array 410 Manager for Windows

NT," Chapter 3 this guide. Each time you reboot your system, following the completion of

"Creating RAIDsets," your Adaptec adapter will be ready for use with your system.

Completing your Configuration Setup under

Windows NT

This chapter contains instructions for how to complete your configuration set up through Disk Administrator under Windows NT.

4.1

Completing Configurations under Windows NT

In order for Windows NT to recognize new RAID Array 410 devices or changes to existing configurations, you must reboot your system to restart Windows NT.

4.1.1

Verifying that hszdisk.sys Loaded

Prior to running Disk Administrator, verify that hszdisk recognizes the devices that you created in the RAID Array 410 Subsystem.

To verify hszdisk, follow these steps:

Look for an entry for hszdisk in the Event Viewer window.

If no entry for the hszdisk appears in the Event View window, go to Chapter 2 of this guide and reinstall hszdisk.

If an entry for hszdisk appears with 0 in the Event column, similar to the screen shown in

Figure 4

−

1, the hszdisk loaded successfully and connected to at least one logical drive in the RAID Array 410. Go on to Section 4.1.3 to complete the new array configuration.

Figure 4

−−

1 How The hszdisk Entry Appears When It Loads Successfully.


Chapter 4. Completing Your Configuration Setup Under Windows NT

If an entry for hszdisk appears with a 1 in the Event column, similar to the screen shown

Figure 4

−

2, the hszdisk did not load successfully due to its not finding any logical drives. If the hszdisk did not load successfully, go to Chapter 3 of this guide, and reconfigure the array. If after reconfiguring the array, hszdisk still fails to load, contact your

Sales Representative.

Figure 4 −− 2 How The hszdisk Entry Appears When It Fails To Load.

3. Close the Event Viewer when you finish verifying hszdisk.sys.

4.1.2

Completing a New RAID Array Configuration

The steps listed in this section are necessary to complete your RAID Array installation. This section describes how to use Disk Administrator to complete a new configuration under

Windows NT. The instructions listed here are summary in nature. For additional information, refer to your Windows NT documentation.

NOTE

To safeguard critical data, backup your system using normal backup procedures before altering device partitions.

To begin, run Disk Administrator from within Windows NT by performing the following steps:

1. Select Program Manager

2. Select Administrative Tools

3. Select Disk Administrator



NOTE

The first time you run Disk Administrator after adding new disks, one or more message window(s) may appear asking you to confirm whether you want to have Disk Administrator provide its

“signature” on the new disks. Confirm doing so (by clicking on

Yes) in order to have Disk Administrator recognize these new disks. For more information on this subject, refer to your Windows

NT documentation.

Figure 4–1 shows the partial screen display for a representative configuration.

Understanding the Disk Administrator Display

Disk Administrator creates a “Bar Chart” display of your disk configuration (see

Figure 4–3), The figure shows that Windows NT has named the various devices that were created using the RAID Array 410 manager graphical user interface. Each disk device found by Windows NT is given a name, e.g., Disk 0, Disk 1, etc. There should be an entry (device) shown for each disk (JBOD) or storageset created.

Windows NT assigns disk names based on the order in which the system drivers “find” disks during Windows NT boot. The RAID Array 410 uses a special disk class driver

(HSZDISK.SYS) that connects to all SWXRC-04 disks before any other disks present in the system are connected. Therefore, the first entries in the Disk Administrator display

(see Figure 4–3) should represent all your RAID Array 410 Logical Disks.

Figure 4–3 Disk Administrator Screen Display


4–4


The figure also shows the corresponding free space for each entity. There should be an entry

(device) shown for each disk (JBOD) or storageset created.

Before proceeding, you should verify the following:

1. There should be an entry in the Disk Administrator display for each of your disks or

RAID Array 410 logical disks.

If there is not, you should go back and recheck your configuration. You may need to verify either the logical or physical (or both) configuration of your RAID Array 410.

2. The capacity shown for each device should match the size of the physical disk or the

RAID Array 410 storageset.

NOTE

Disk Administrator displays the “usable” capacity of a RAIDset and

Mirrorset, not the combined total of the physical members.

If it does not, you should recheck the logical configuration for the RAID Array 410 and its members.

To complete your configuration under Windows NT, perform the following steps:

1. Create partitions as follows:

•

For each disk shown by first select (click on) the partition area that you wish to create.

•

Then, click on the Partition pull-down menu. From the Partition pull-down menu, choose Create (see Figure 4–4).

Doing so opens the Create window (see Figure 4–5).

NOTE

A disk cannot be accessed unless it contains at least 1 valid partition that was created under disk administrator.

See Figure 4–5 Create Primary Partition Window

In the window, enter the size partition you want, then click on OK . (Depending upon the partition size you choose, a message window may appear asking you to confirm your selection.)

2. Continue to create new partitions until all disks have been partitioned.

3. Optional: Make disk logical names permanent.

The process of creating partitions assigns a logical name (the letter “C,” “D,” etc.) to each partition. These letter assignments, under Windows NT, will normally “float.”

That is, they are subject to changing (after reboot), if the disk configuration changes.

You may, however, make these assignments “permanent.” (For more information on this subject, you should consult your Windows NT documentation.) If you wish to make the letter assignments “permanent,” access the Tools pull-down menu. From the choices given, select Drive Letter then choose To Assign. This process must be repeated for each partition (drive letter) that you wish to make “permanent.”

4. When you have created all your partitions, go back to the Partition pull down menu and click on Commit Changes Now (see Figure 4–4).

A message window will then appear asking you to confirm that you wish to commit these changes.

After confirming that you wish to commit the changes, a new message screen should appear advising that the commit changes action was successful.

NOTE

A message window will appear following this step asking you if you wish to save a copy of the configuration to a floppy. You may do so at this time, as prompted by the screen display.

5. While still running Disk Administrator, click on the Tools pull-down menu, then select Format (see Figure 4–6).

The Format menu choices (see Figure 4–7) allow you to choose either FAT or

NTFS . You must select one of these file system options for the disk to be usable.

You may also choose the Quick Format option. Select OK to begin the format process. For further information regarding these options, refer to your Windows NT documentation.

A message window appears advising you when the formatting is complete.

NOTE

A third format, HPFS, is not an available choice under Disk Administrator. The HPFS format choice may only be made from a command prompt window. Refer to your Windows NT documentation for more details on this subject.

6. Continue to format each new partition until all partitions have been formatted.

7. When all partitions have been formatted, close Disk Administrator. At this point, the configuration has been completed, and is recognized by Windows NT.

4.1.3

Changes to RAID Array Configuration

NOTE

To safeguard critical data, backup your system using normal backup procedures before altering device partitions.

Do not alter partitions that contain important data.

When making changes to an existing RAID Array configuration, any existing disk partitions to be changed (or removed) must first be deleted using Windows NT Disk Administrator.

After they have been deleted, you may use the RAID Array 410 Manager to create new Storagesets (refer to the RAID Array 410 Manager for Windows NT, to make the changes).

To remove disk partitions, run Disk Administrator from within Windows NT by performing the following steps:

1. Select Program Manager

2. Select Administrative Tools

3. Select Disk Administrator

Delete the partitions you intend to change (or remove) by performing the following steps:

1. From Disk Administrator , select (click on) the partition you wish to delete.

2. Pull down the Partition menu.

3. Choose Delete , then continue.

4. Continue selecting and deleting the partitions until you have done so to all the partitions you wish to change.

5. Go back to the Partition pull down menu and click on Commit Changes Now .

6. At this point all the disks you intend to reconfigure have been deleted from Windows

NT. You may now reconfigure the RAID Array using the RAID Array 410 Manager as described in the manual RAID Array 410 Manager for Windows NT User’s Guide.



7. You now need to reboot your system for changes made thus far to be recognized by

Windows NT.

8. After rebooting, you need to perform the steps listed at the beginning of this chapter,

Section 4.1.1, Completing a New RAID Array Configuration, in order for the changes to take effect.

9. After completing the steps described in Section 4.1.1, Completing a New RAID Array

Configuration, you are done.

Accessing the Command Line Interpreter (CLI)

This chapter contains instructions for accessing the Command Line Interpreter (CLI). The CLI is used to access various maintenance and diagnostic programs.

B.1

What is the CLI?

The Command Line Interpreter (CLI) is an alternate user interface for the RAID 410 controller. Using a connection between the controller’s maintenance port and your computer system’s communications port, the CLI can be used to enter commands, access various reports, and run diagnostic tools. For additional information regarding these commands, reports, and tools, refer to the SWXRC RAID Array Controller User’s Guide (EK-SMCS1-UG).

B.2

Accessing the CLI

NOTE

Before performing the following procedures, you must exit and close the RAID Array 410 manager graphical user interface. This is necessary to permit the serial data line and associated communications port on the computer system to run with the terminal emulator program, as described below.

The CLI is accessed from your system’s Windows NT Terminal program (in the Accessories group). The Terminal program uses the serial data line that connects the maintenance port on a SWXRC-04 controller to your computer system communications port (Com1, Com2, etc.).

Although you may use a separate maintenance terminal, we recommend using the Terminal program. Doing so simplifies the procedure because the serial data line already has been connected as part of your system installation procedure. You can also use most commerciallyavailable communications programs.

The Following procedures assumes your serial data line remains connected from the

SWXRC-04 controller maintenance port to the communications port on your computer system. Follow these procedures to access the CLI:

1. Start the communications program on your system.

2. Set the communications program to use the serial port ( COM1, COM2 , etc.) that is connected to the controller.

EK–SMRAC-IG. C01 B–1

Getting Started – RAID Array 410 for Windows NT –Intel

3. Set the communications parameters to:

9600 baud

8 bits

1 stop bit

No parity

4. From your communication program, issue a connect command to establish a connection with the controller, and then press the Enter key. You should see the CLI prompt, which looks similar to

SWXRC>

From this prompt, you may issue your CLI commands. For further information regarding

CLI commands, reports, etc., refer to the SWXRC RAID Array Controller User’s Guide (EK-

SMCS1-UG).
