Chapter 1. Getting Started with PC Server 330 13

Arranging Your Workspace

To get the most from your server, arrange both the equipment you use and your work area to suit your needs and the kind of work you do. Your comfort is of foremost importance, but light sources, air circulation, and the location of electrical outlets also can affect the way you arrange your workspace.

Comfort

Although no single working position is ideal for everyone, here are a few guidelines to help you find a position that suits you best.

Sitting in the same position for a long time can cause fatigue. A good chair can make a big difference. The backrest and seat should adjust independently and provide good support. The seat should have a curved front to relieve pressure on the thighs. Adjust the seat so that your thighs are parallel to the floor and your feet are either flat on the floor or on a footrest.

When using the keyboard, keep your forearms parallel to the floor and your wrists in a neutral, comfortable position. Try to keep a light touch on the keyboard and your hands and fingers relaxed. You can change the angle of the keyboard for maximum comfort by adjusting the position of the keyboard feet.

Viewing Distance

Lower Back Support

Seat Height

Adjust the monitor so the top of the screen is at, or slightly below, eye level. Place the monitor at a comfortable viewing distance,

14 PC Server 330 User's Handbook

Arranging Your Workspace

usually 51 to 61 cm (20 to 24 in.), and position it so you can view it without having to twist your body. Also position other equipment you use regularly, such as the telephone or a mouse, within easy reach.

Glare and Lighting

Position the monitor to minimize glare and reflections from overhead lights, windows, and other light sources. Even reflected light from shiny surfaces can cause annoying reflections on your monitor screen. Place the monitor at right angles to windows and other light sources, when possible. Reduce overhead lighting, if necessary, by turning off lights or using lower wattage bulbs. If you install the monitor near a window, use curtains or blinds to block the sunlight. You might have to adjust the Brightness and Contrast controls on the monitor as the room lighting changes throughout the day.

Where it is impossible to avoid reflections or to adjust the lighting, an antiglare filter placed over the screen might be helpful. However, these filters might affect the clarity of the image on the screen; try them only after you have exhausted other methods of reducing glare.

Dust buildup compounds problems associated with glare. Remember to clean your monitor screen periodically using a soft cloth moistened with a nonabrasive liquid glass cleaner.

Air Circulation

Your server and monitor produce heat. Your server has one or more fans that pull in fresh air and force out hot air. The monitor lets hot air escape through vents. Blocking the air vents can cause overheating, which might result in a malfunction or damage. Place the server and monitor so that nothing blocks the air vents; usually, 51 mm (2 in.) of air space is sufficient. Also, make sure the vented air is not blowing on someone else.

Chapter 1. Getting Started with PC Server 330 15

Getting Help on the World Wide Web

Electrical Outlets and Cable Lengths

The location of electrical outlets and the length of power cords and cables that connect to the monitor, printer, and other devices might determine the final placement of your server.

When arranging your workspace:

 Avoid the use of extension cords. When possible, plug the

server power cord directly into an electrical outlet.

 Keep power cords and cables neatly routed away from

walkways and other areas where they might get kicked accidentally.

Monitoring Status of the Adapter in the Local System

You can view the configuration or monitor the ServeRAID adapter in the local system by using the Administration and Monitoring Utility. This utility supports the following operating systems.

 OS/2  Novell NetWare  Windows NT

Because the monitoring programs reside on top of your operating system, you can perform tasks such as the following from your active operating system Desktop:

 Select the adapter that you want to monitor  View information about the states of drives connected to the

adapter and change the drive state

 Replace a defunct hard disk drive

Refer to the README file on the IBM PC ServeRAID Device Driver, Administration and Monitoring Diskette for instructions on how to install and use these monitoring programs.

Chapter 2. Configuring Your Disk Arrays 23

Monitoring Status of the Adapter in a Remote System

The ServeRAID adapter can be remotely monitored using the Client/Server environment which is supported by using TCP/IP. The Server part of the Client/Server environment runs on the system containing the adapter and is supported by the following operating systems.

 Novell NetWare  Windows NT  OS/2  SCO OpenServer

The Client part of the Client/Server environment runs in the following Windows environments:

 Windows NT Server Version 3.51  Windows NT Workstation Version 3.51

 Windows 95

The Client program includes many of the functions contained in the IBM PC ServeRAID configuration program, such as, adding or removing capacity dynamically when creating or deleting an array. You can start the Administration and Monitoring program from your active operating system Desktop.

This monitoring program allows you to view the ServeRAID configuration and associated devices, reassign a drive to replace a defunct drive, create a logical drive, create an array, and delete an array.

24 PC Server 330 User's Handbook

In addition, in an array that contains only one logical drive, and the total number of logical drives in all arrays is less than eight, you can change the logical drive RAID level from level 0 to level 5 (or level 5 to level 0). The logical drive is not accessible during the conversion process. Make sure that you backup your data before initializing a RAID conversion process.

Note: In the event of a power loss or a hard disk drive failure, the

data in the logical drive undergoing the RAID conversion can be lost.

Refer to the README file on the IBM PC ServeRAID Device Driver, Administration and Monitoring Diskette for instructions on how to install and use this monitoring utility program.

Device Drivers

Device drivers are programs designed to support a specific type of hardware device. They provide instructions that enable the server to interact with the device, or to take advantage of a device's special feature. The ServeRAID adapter requires the installation of device drivers.

Configuring Your Disk Arrays

The ServeRAID configuration program allows you to view the current disk-array configuration, change or delete existing arrays, create and initialize new disk arrays, and perform many other disk-array tasks.

You must configure your disk-arrays before you install your operating system. Once your disk-arrays are configured, you must run the Administration and Monitoring program appropriate for your operating system to receive messages and warnings regarding the status of the logical and physical hard disk drives.

Starting the Configuration Program

1. To start the ServeRAID configuration program, insert the ServeRAID Adapter Configuration Diskette into the primary

Chapter 2. Configuring Your Disk Arrays 25

diskette drive and turn on the system. If the system is already turned on, press Ctrl+Alt+Del.

Each time your system starts, the ServeRAID adapter performs a power-on self-test (POST). The POST checks the configuration information on the adapter and on the configured hard disk drives.

 If POST does not detect changes in the adapter

configuration or an adapter hardware problem, continue with step 2 on page 27.

 If POST detects changes in the adapter configuration or

detects an adapter hardware problem, error messages appear on the screen. Refer to “ServeRAID Adapter POST and Setup Messages” on page 282, then return here and continue with step 2 on page 27.

26 PC Server 330 User's Handbook

2. If you have more than one ServeRAID adapter installed in your system, the following screen appears. You can install a maximum of three ServeRAID adapters in your system and you must configure each adapter separately.

Note: It is good practice to synchronize logical drives with

RAID levels 1 and 5 weekly.

 Select Rebuild/Device Management to rebuild logical drives.

When you replace a defunct drive in a critical (CRT) logical drive, the data is rebuilt on the new physical drive before the state of the logical drive is changed to OKY. The rebuild operation is supported only for RAID levels 1 and 5. You also can use this option to define or redefine the state of a physical drive, display drive information, and clear the device-error table.

 Select Advanced Functions to change the write policy (the way

data is written to the drive), to save your configuration information to a diskette, to restore your configuration from a diskette, or to change ServeRAID adapter parameters.

2. You can select any of the choices that appear on the menu.

3. The Bay/Array selection list shows 15 bays for each of the adapter's three channels. For each bay that contains a drive, the

Chapter 2. Configuring Your Disk Arrays 31

list indicates the physical drive state and the array in which the drive is grouped. For example, in the illustration, the drive in Channel 2, Bay 1 has a drive state of ONL (online) and is a part of Array B. Selections are made from this list to determine which bays (hard disk drives) are in your arrays.

Notes:

a. The Bay/Array area on the screen does not reflect the

physical configuration of the server. In your server, you have one “bank” of hot-swap drive bays, bank C. The default numbering for the hot-swap drive bays is numbered 1 through 6 (from top to bottom). Refer to “Installing Internal Drives” on page 149. for the physical location of the hard disk drives.

b. The internal drives in your server come connected to

Internal Channel 3 of the ServeRAID adapter. To attach external devices to your server, you can use the

External Channel 1 connector. You can also attach external devices to a separately purchased cable, and then connect the cable from the Internal Channel 2 connector on the adapter and out the back of your server, either through the knockout panel or by removing an expansion slot cover.

c. The Bay Number corresponds to the SCSI ID of the device

plus 1.

4. The Array list indicates the array ID and the size (in megabytes) of the array. When a drive is being rebuilt, this area and the Logical Drive list area show the progression of the rebuild process.

5. The Logical Drive list identifies the logical drive installed (for example, A1), including the size of the logical drive, the RAID level assigned to the logical drive, the date the logical drive was created, the status of the logical drive, and its write policy.

Note: Logical drives are numbered 0 through 7 in ascending

order from top to bottom. They are position dependent, for example, logical drive 3 will always display on the fourth line (B0) even if logical drives 0, 1, and 2 are deleted.

32 PC Server 330 User's Handbook

6. The information area tells you the action you can perform on this screen or pop-up.

Logical Drive States

The state of a logical drive is determined by the state of its physical drives. Replacing a defunct drive with a good drive changes the state of the logical drive from offline (OFL) to critical (CRT) or good (OKY). When you replace a physical defunct drive in a critical (CRT) logical drive, the data is rebuilt on the new physical drive before the state of the logical drive is changed to OKY.

State Meaning CRT A logical drive that is defined as RAID level 1 or 5

contains a defunct physical drive. A critical (CRT) logical drive is accessible despite a physical drive failure.

FRE The drive is not defined. LDM The logical drive is undergoing a RAID level change. This

state is available only in the remote system of the Administration and Monitoring program.

OKY The drive is in a good functional state. OFL The logical drive is offline and not accessible. This state

occurs if one or more physical drives in a nonredundant logical drive (RAID level 0) is defunct. This state also occurs when two or more physical drives in a redundant logical drive (RAID levels 1 and 5) are defunct.

SYS Reserved state used by the ServeRAID adapter. Note: If the logical drive is critical, you must replace and rebuild

the defunct drive.

Physical Device States

The Bay/Array selection list defines the physical devices connected to each channel as follows:

State Meaning CDR A CD-ROM drive is installed.

Chapter 2. Configuring Your Disk Arrays 33

DDD A drive in the Online (ONL) or Rebuild (RBL) state has

become defunct; it does not respond to commands, which means that the adapter cannot communicate properly with the drive.

A hard disk drive in the DDD state does not necessarily mean that the drive needs to be replaced. In order to determine if the drive should be replaced, you should do the following:

1. Check to ensure that all cables connected to the backplane and to the hard disk drive are connected properly. Also, check to ensure all cable inside the server are connected properly.

2. Make sure tha the hot-swap drive trays are seated properly in the drive bay.

If the hard disk drive still does not function after you have performed these steps, replace the drive.

DHS A hot-Spare or standby hot-spare drive enters the Defunct

Hot-spare (DHS) state if it fails to respond to the adapter commands.

EMP No device is present in the bay. This state is represented

with dashes (– – –) on the ServeRAID configuration screen, or a blank space on the Administration and Monitor screen.

HSP A hot-spare drive is a hard disk drive that is defined for

automatic use when a similar drive fails. The drive capacity of the replacement HSP drive must be equal to or greater than the capacity of the drive being replaced. You must have at least four hard disk drives if you want a hot spare and RAID level 5.

ONL The drive is online and part of an array. RBL The drive is being rebuilt. A physical hard drive can

enter the RBL state if:

 A good working drive replaces a defunct (DDD) drive

that is part of the critical (CRT) logical drive. At the end of a successful rebuild, the state of the physical

34 PC Server 330 User's Handbook

drive becomes online (ONL), and the state of the corresponding logical drives changes to OKY.

 The HSP or SHS drive is added to the array and the

state changes from HSP or SHS to RBL. At the same time, the DDD drive is removed from the array and its state changes to DHS from DDD. The ServeRAID adapter will then automatically reconstruct data in the RBL drive. The state of the corresponding logical drive remains in CRT (if RAID level 1 or 5) or OFL (if RAID level 0) during the rebuild process. When the rebuild completes successfully, the device state changes from RBL to ONL and the logical drive state changes from CRT to OKY.

 A Ready (RDY) or Standby (SBY) drive replaces a

defunct (DDD) drive that is part of the critical (CRT) logical drive. The state of the RDY or SBY drive becomes RBL. When the rebuild completes successfully, the state changes to ONL. The DDD drive is removed from the logical drive and becomes DHS.

For more information on rebuilding a drive, refer to “Important Information for Rebuilding a Logical Drive” on page 60.

RDY A ready drive is recognized by the adapter and is

available for definition. A RDY drive becomes EMP when the drive is physically removed from the bay.

SBY A standby drive is a hard disk drive that has been spun

down by the adapter. Devices such as tape drives and CD-ROM drives are also considered to be in a Standby state.

SHS A standby hot-spare is a hot-spare drive that has been

spun down by the adapter. If a drive becomes defunct and no suitable hot-spare drive is available, a standby hot-spare of the appropriate size spins up, and enters the RBL state. You must have at least four hard disk drives, if you want a standby hot-spare and RAID level 5.

TAP A tape drive is installed.

Chapter 2. Configuring Your Disk Arrays 37

Creating/Deleting Disk Arrays

This section contains the common tasks for configuring disk arrays. Procedures to complete these tasks are in this section as follows:

 “Creating a Disk Array” on page 40.  “Defining Logical Drives” on page 41.  “Defining a Hot-Spare Drive” on page 47.  “Deleting a Disk Array” on page 49.  “Deleting a Logical Drive” on page 51.  “Redefining Space in an Array” on page 52.  “Setting Device States” on page 54.

You can create disk arrays from your existing drives, and define and delete logical drives. Later, you can add storage capacity to your server without disturbing existing data by installing additional hard disk drives and creating additional arrays. You can use the remote mode of Administration and Monitoring program or the ServeRAID configuration program to create a disk array.

Using the remote mode of the Administration and Monitoring program, you can add a logical drive to an existing array, if the array has free space to create the logical drive. You can also create a new array to add additional logical drives. By adding additional logical drives, you can dynamically add capacity to your server, if your operating system supports it. Refer to the README file on the Device Driver/Administration and Monitoring diskette for instructions on using the Administration and Monitoring program.

Understanding Logical Drives

It is helpful to understand how the system manages logical drives and how many you can define.

When you create an array, you are combining several hard disk drives into one storage area. The array then can be used as a single logical drive or can be subdivided into several logical drives. A logical drive of a disk array can be any size you choose within the size limitations of the array. Each ServeRAID adapter supports up to eight independent arrays and a total of eight logical drives.

38 PC Server 330 User's Handbook

Each array can be formed from a maximum of 8 or 16 drives. An array can span all channels.

Note: When the strip unit size is 8 K or 16 K, the maximum

number of physical drives in an array is 16. When the strip unit size is 32 K or 64 K, the maximum number of physical drives in an array is eight.

Understanding Hard Disk Drive Capacities

It is important to understand the implications of hard disk drive capacities and how they influence the way you create disk arrays.

Although the drives in the disk array can be of different capacities (for example 1 GB or 2 GB), they are treated in the disk array configuration as if they all have the same capacity, that is, the capacity of the smallest disk drive. Therefore, if you have four drives of 1 GB, 1 GB, 1 GB, and 2 GB grouped in one disk array, the total capacity of the array is 1 GB times 4, or 4 GB (instead of the 5 GB physically available).

Notes:

1. With RAID level 0, the total capacity of the array without protection would be 4 GB. With RAID level 1 protection, the usable data capacity would be 2 GB. With RAID level 5 protection, the usable data capacity would be 3 GB.

2. When referring to hard-disk-drive capacity, GB means 1 000 000 000 bytes; total user-accessible capacity may vary depending on operating environment.

Chapter 2. Configuring Your Disk Arrays 39

Creating a Disk Array

To create a disk array:

1. Start the ServeRAID configuration program (refer to “Starting the Configuration Program” on page 25).

Note: If you want to create an array using hard disk drives in

an existing array, refer to “Redefining Space in an Array” on page 52.

2. Select Create/Delete Array/Log Drive from the Main Menu and press Enter.

3. Select Create Disk Array from the Create/Delete Array menu. The cursor will be active in the Bay/Array selection list.

5. When you have selected all the drives you want to include in

the array, press Esc. The cursor will become active in the menu. Note: When the stripe unit size is 8 K or 16 K, the maximum

number of drives in an array is 16. When the stripe unit size is 32 K or 64 K, the maximum number of drives in an array is eight.

6. If you have drives you did not use in the array and you want to create another array, you can do one of the following:

 Define the logical drive or drives for that array; then create

another array and its logical drives. Refer to “Defining Logical Drives.”

 Create another array now by repeating steps 2 through 5 in

this procedure; then define logical drives for all arrays. Note: You must define at least one logical drive for each

array created before you can exit from the ServeRAID configuration program.

7. If you change your mind after selecting the drives for an array, you can delete the array (by selecting Delete Disk Array from the Create/Delete Array menu) and then begin again.

Defining Logical Drives

You cannot leave the ServeRAID configuration program until you define the logical drives for any created arrays.

To define a logical drive:

1. Start the ServeRAID configuration program (refer to “Starting the Configuration Program” on page 25).

3. Use the Up Arrow (↑) key or the Down Arrow (↓) key to highlight the array you want to define; then press Enter. The Select RAID Level pop-up window appears, and the cursor is active in the window.

4. Select a RAID level from the pop-up window and press Enter.

Notes:

a. The system automatically assigns RAID level 0 to any

logical drives defined in an array containing only one hard disk drive. When this is the case, the Select RAID Level pop-up window will not appear.

b. If you have two hard disk drives in the array, the Select

RAID Level pop-up window appears, but RAID level 5 is not selectable. You need at least three hard disk drives in an array to assign RAID level 5 to one of the logical drives.

c. You can define more than one logical drive for your array.

The maximum number of logical drives you can define is eight. If you plan to change RAID levels using the remote mode of the Administration and Monitoring program, the

42 PC Server 330 User's Handbook

maximum number of logical drives you can define is seven. The RAID conversion procedure requires one free logical drive.

d. The maximum number of physical drives in an array is

eight or 16, depending on the stripe unit size. When the stripe unit size is 8 K or 16 K, the maximum number of drives in an array is 16. When the stripe unit size is 32 K or 64 K, the maximum number of drives in an array is eight.

5. Use the Up Arrow (↑) key or the Down Arrow (↓) key to highlight the RAID level you want to assign to the logical drives, then press Enter.

Note: The RAID level you assign to a logical drive can

influence the space needed for that drive, therefore; you must assign a RAID level before you enter the size of the logical drive.

The Logical Drive list contains the drive ID and the size (the total number of MB in the array) of the array, the size of each logical drive, the RAID level you assign to that logical drive, and the date that you created the logical drive.

The status of the logical drive also is shown. OKY means that the drive is in a good functional state. CRT means that you must replace the defunct hard disk drive and rebuild the drive.

Chapter 2. Configuring Your Disk Arrays 43

(You will receive a message telling you the drive is in a CRT state if you are running the Administration and Monitoring program.) OFL means that the logical drive is unrecoverable; the data in that drive is lost.

If this is the first logical drive to be defined, the Logical Drive Size pop-up window shows the amount of space in the array that is available for additional logical drives.

If other logical drives have been defined, the Allocation Table appears, showing the logical drive sizes already created, and the amount of free space available.

6. Type the size, in megabytes, that you want for the logical drive;

then press Enter. The Confirm pop-up window appears asking you to confirm your action.

The information about the new logical drive appears in the Logical Drive list.

Note: The size appearing in the Logical Drive list might be

different from the size you typed. The size of a logical drive is determined by a number of factors, but basically the size must be divisible by the number of data drives in the array.

Consider the following scenarios:

Scenario 1

The array consists of three 1 GB drives. You assign RAID level 0 (which uses all the drives in the array with no parity storage), and type 1ððð MB. The number in the Size (MB) field will show 999, which is the number closest to and lower than 1000 that is divisible by 3.

Scenario 2:

The array consists of three 1 GB drives. You assign RAID level 1, which provides a disk mirroring that stripes data across all drives in the array. Because the data is mirrored, the capacity of the logical drive is 50 percent of the physical capacity of the hard disk drives grouped in the array. Type 1ððð MB; the number in the Size (MB) field will be 999. The physical capacity used is 2000 MB, twice that of the logical drive size. The

44 PC Server 330 User's Handbook

number that is closest to or lower than 2000 and divisible by 3 is

1998. The logical drive size is 999, which is 50% of the physical capacity.

Scenario 3

The array consists of three 1 GB drives and you assign RAID level 5. Data is striped across all three drives in the array, but the space equivalent to that of one drive is used for redundant storage. Therefore, if you type 1ððð MB, the number in the Size (MB) field remains 1000 because it is divisible by 2 (drives), which is the space available for data.

If you do not use the entire array for this logical drive, you can create another by assigning either the same or a different RAID level for an additional logical drive. You can have as many as eight logical drives among eight disk arrays.

7. To define more logical drives, repeat steps 1 through 6 of this procedure.

8. To leave this screen, select Exit or press Esc.

9. To ensure that your server operates correctly, you must select Initialize Logical Drive for proper operation. This sets the drive to a predetermined state. The initialization process overwrites any data on the drive with zeros.

a. Select Initialize/Synchronize Log Drive from the Main

Menu, then select Initialize Logical Drive.

b. Select the logical drives you want to initialize from the

Logical Drive list by pressing the Spacebar (the selected drives will appear highlighted). To start the initialization, press Enter. The Confirm pop-up window appears, asking you to confirm your action.

Attention: If you select Yes in the Confirm pop-up window, information in the logical drive will be overwritten with zeros.

Chapter 2. Configuring Your Disk Arrays 45

c. Select Yes to confirm that you want to initialize the logical

drive. The initialization process begins. You can see its progress in

the Pct. Int. (percent initialized) column of the Logical Drive list.

d. To stop the initialization at any time, press Esc. Then, press

Esc again to return to the previous menu, or press Enter to continue initializing the drive.

e. If you defined the drive as RAID level 5, you must

synchronize the drive before storing data.

f. Select Initialize/Synchronize Log Drive from the Main

Menu; then, select Synchronize Logical Drive. Note: Once synchronization starts, it cannot be interrupted

until the operation is complete.

Your logical drives are now created and ready for use.

10. To back up the disk-array configuration to diskette, you will need a 3.5-inch, formatted diskette. To back up the disk array configuration:

a. Select Advanced Functions from the Main Menu.

b. Select Backup config. to diskette.

Follow the instructions on the screen. A pop-up window shows the default file name of CONFIG. You can change the file name by typing over the default. The Backup program will assign a file-name extension of .ips.

Redefining Space in an Array

You can redefine space in a disk array in a number of ways. For example, you can combine a number of small logical drives to create a larger one, or you can redefine the existing logical drive into several smaller drives. Also, you can install additional hard disk drives and create a larger logical drive than was possible with the existing storage capacity.

One method to redefine space in an array is to change the RAID level assigned to a logical drive. For example, if you assigned RAID level 1 to a logical drive and then decided you needed the capacity offered with RAID level 5, you can use this procedure to replace the existing logical drive with a logical drive assigned the new RAID level.

To redefine the space in a disk array, first you must delete the existing array.

Attention: In all cases, when you delete an array, all the data and programs in the array are lost.

Note: You will need a blank 3.5-inch formatted diskette to back up

the configuration file, as described in this procedure.

1. Back up all data and programs in the array. Note: Back up the data before you delete the existing array.

You might want to use a high-speed back up device, such as a tape drive, to back up large amounts of data.

2. If needed, install additional hard disk drives. Refer to “Understanding Hard Disk Drive Capacities” on page 39 for information about drive sizes.

52 PC Server 330 User's Handbook

3. Start the ServeRAID configuration program (refer to “Starting the Configuration Program” on page 25).

4. To delete the existing array:

a. Select Create/Delete Array/Log Drive from the Main Menu.

b. Select Delete Disk Array. The cursor will be active in the

Bay/Array selection list.

c. Select the array that you want to delete.

d. Press Del. The Confirm pop-up window appears.

Attention: All the data in the array is lost during this procedure. Be sure to back up all data and programs that you want to save.

e. Select Yes to delete the array. Select No if you do not want

to delete the array. Note: To use the hard disks from the existing array when

creating a new array, you must confirm the deletion of the existing array. After you make your selection, the Confirm pop-up window disappears, and the cursor becomes active in the menu.

5. If you want to define a hot-spare drive, refer to “Setting Device States” on page 54 for step-by-step instructions.

6. To create a new disk array and define logical drives, refer to “Creating a Disk Array” on page 40 for instructions.

7. After you have established the new array and logical drive or drives, select Initialize/Synchronize Log Drive from the Main Menu; then, select Initialize Logical Drive to prepare the drives in the array to receive data. This sets the drive to a predetermined state. Any data existing in the drive is overwritten with zeros.

8. If you defined the drive as RAID level 5, you must synchronize the drive before storing data. Select Initialize/Synchronize Log

Drive from the Main Menu; then, select Synchronize Logical Drive.

Note: After synchronization starts, you cannot interrupt it until

the operation is complete.

Chapter 2. Configuring Your Disk Arrays 53

9. When the synchronization process completes, insert a blank

3.5-inch formatted diskette in the primary diskette drive and select Advanced Functions from the Main Menu; then, select Backup config. to diskette. Follow the instructions on the screen.

10. Exit the ServeRAID configuration program by pressing Esc or selecting Exit from the Main Menu. A Confirm pop-up window appears asking you to confirm your action.

11. Reinstall your operating system and device drivers, then restore your data and programs.

Maintaining Your Disk Arrays

This section contains procedures for defining the state of a hard disk drive, information about the status indicators for logical and hard disk drives, and instructions for replacing defunct drives. It also contains procedures for displaying drive information and erasing the device error table. This section provides information about the status indicators for logical and hard disk drives, and the results of a hard disk drive failure. It also contains procedures for defining the state of a hard disk drive and replacing defunct drives.

Results of a Hard Disk Drive Failure

Depending on the circumstances, a drive failure can result in several possible situations.

Scenario 1:

 Only one hard disk drive fails.  A hot-spare drive is defined that is the same size as the failed

drive.

The hot spare will take over immediately. Note: Any logical drives with RAID level 0 are blocked during the

Rebuild process and remain blocked until the rebuild process completes. The ServeRAID configuration program unblocks all drives at the end of the rebuild operation.

All data in logical drives assigned RAID level 0 will be lost.

56 PC Server 330 User's Handbook

Scenario 2:

 Only one hard disk drive fails.  A hot-spare drive is not defined or is smaller than the failed

drive.

 The logical drives in the array are assigned RAID levels 0, 1,

and 5, or a combination of these three levels.

All data in logical drives assigned RAID level 0 will be lost. In this array, the logical drives that are assigned RAID level 1 or 5 will be in Critical (CRT) state. The logical drives assigned RAID level 0 will be in the Offline (OFL) state.

Scenario 3:

If more than one drive in an array fails, all the data is lost in all of the logical drives of the array. For this reason, it is important that you replace and rebuild a DDD drive as soon as possible.

Logical and Hard Disk Drive Status Indications

The status of the hard disk drive determines the status of the logical drives in the array in which the hard disk is grouped.

 A single hard disk drive failure, (indicated by a DDD state in

the Bay/Array selection list), generates a CRT state for the array's logical drives that are assigned levels 1 and 5. Data in logical drives with a CRT state is not lost, but you must replace the failing hard disk drive promptly and perform a Rebuild operation. If two hard disk drives fail, all of the data in the array is lost.

After you install a new hard disk drive, the Rebuild process changes the drive state from DDD to RBL, if the array contains a CRT logical drive. After the Rebuild process completes, the hard disk drive state changes from RBL to ONL.

 A multiple hard disk drive failure causes logical drives in that

array to have an OFL state. This means that data is lost in all the logical drives in that array, regardless of which RAID level is assigned.

Chapter 2. Configuring Your Disk Arrays 57

Replacing a Faulty Drive

If you are not using or installing a SCSI-2 Fast Hot Swap Drive Tray III or a SCSI-2 Fast/Wide Hot Swap Drive Tray III, check your manufacturers instructions for specific details for detecting a failing hard disk drive.

Note: The LEDs on the SCSI-2 Fast Hot Swap Drive Tray III or the

SCSI-2 Fast/Wide Hot Swap Drive Tray III provide information about the status of the drive.

supplied to the drive. The hot-swap drive can be removed safely.

Check the drive for damage. If the drive is not damaged, check the position of the drive. If it is not inserted correctly, reposition the drive. Verify that the drive is positioned correctly.

If you are using one of the Administration and Monitoring programs provided with your ServeRAID adapter, you can use it to identify the defunct drive and designate a drive to replace the defunct drive without restarting the server. Refer to the README file on the Device Driver/Administration and Monitoring diskette for instructions for your operating system.

Do the following steps to replace a faulty drive using the ServeRAID configuration program:

1. Start the ServeRAID configuration program (refer to “Starting the Configuration Program” on page 25).

If the drive failed while the system was powered down, a message appears the next time you turn on the system.

2. Physically replace the drive or assign a hot-spare or other appropriate drive as a replacement.

Attention: Removing the wrong hard disk drive can cause loss of all data in the array.

3. If you are assigning a hot-spare or another appropriate drive to replace the defunct drive, go to “Important Information for Rebuilding a Logical Drive.”

Chapter 2. Configuring Your Disk Arrays 59

4. If you are physically replacing the hard disk drive, refer to your manufacturers installation instructions.

Important Information for Rebuilding a Logical Drive

Review this section before you rebuild a logical drive.

 If the logical drive is critical, you must rebuild the defunct hard

disk drive.

 Data in a logical drive assigned or defined RAID level 0 is lost

during a rebuild. If you backed up your data before the drive failed, you can restore the data to the new drive.

 If a physical hard disk drive being rebuilt is part of a logical

drive defined as RAID level 0, 1 or 5, any RAID level 0 drive is blocked to external access during the rebuild.

– If you initiated the rebuild through the Administration and

Monitoring program, you must unblock the RAID level 0 drive when the rebuild is complete.

– If you initiated the rebuild through the ServeRAID

configuration program and the rebuild was interrupted, drives with RAID Level 0 can be unblocked by restarting the server.

 Only one rebuild operation can take place at a time.  The hard disk drive being rebuilt must be the same size or

larger than the failed drive.

 If multiple hot-spare drives are available, the adapter searches

all bays on each Channel for a hot-spare drive of the appropriate size; the first one found enters the Rebuild state.

 An automatic hot-spare rebuild will take place if:

– The physical drive that failed is part of a RAID level 1 or 5

logical drive.

– A HSP or SHP drive is available the moment the drive fails

and no rebuild, synchronization, or RAID level change operation is in progress.

 Under the following circumstances, a Rebuild operation can be

completed quickly:

60 PC Server 330 User's Handbook

– The defunct (DDD) drive was not defective. – The drive is in the same bay. – No write operations or configuration changes have occurred

that require rebuilding data in that drive.

Rebuilding a Logical Drive

If you are using one of the Administration Monitoring programs provided with your ServeRAID adapter, you can identify the defunct drive and designate a drive to replace the defunct drive without restarting the server. Refer to the README file on the Device Driver/Administration and Monitoring diskette for instructions on your operating system.

To replace a faulty drive using the ServeRAID configuration program:

1. Start the ServeRAID configuration program (refer to “Starting the Configuration Program” on page 25).

The Device Error Table, located in the adapter's NVRAM, collects statistics on the number and type of errors that occurred on all hard disk drives attached to the ServeRAID adapter.

 Soft Error displays the number of SCSI Check Condition

status messages returned from the drive (except Unit Attention) since the Device Error Table was last cleared.

 Hard Error displays the number of SCSI I/O processor

errors that occurred on the drive since the Device Error Table was last cleared. It also indicates if the drive exceeded the Predictive Failure Analysis (PFA) threshold.

Note: If the drive exceeded the PFA threshold, the hard

disk reports a change in the operating conditions. Continue with operation and call for service within 24 hours. For RAID level 0, back up your logical drives.

 Parity Error displays the number of parity errors that

occurred on the SCSI bus since the Device Error Table was last cleared.

 Misc Error displays the number of other errors (such as

selection timeout, unexpected bus free, or SCSI phase error) that occurred on the drive since the Device Error Table was last cleared.

5. Press Esc to return to the previous menu.

Note: The status of the hard disk drive determines the status of the

logical drives in the array in which the hard disk drive is grouped.

After correcting a problem with the disk array, you might want to clear the Device Error Table so that you can identify any subsequent errors quickly. Select Erase Device Error Table from the Rebuild/Device Management menu and press Enter to clear the table.

Additional Disk-Array Tasks

This section contains procedures for performing additional, less common, disk-array tasks. You can select and of the following:

 Back up configuration to diskette

Chapter 2. Configuring Your Disk Arrays 63

 Restore configuration to diskette  Change the write policy  Change the RAID parameters  Run Subsystem diagnostic test  Format a drive  Reset the adapter configuration

 Configuration Synchronization

 Display/Change the ServeRAID adapter parameters

Attention: Notices appear throughout this section to alert you about potential loss of data. Similar warning messages appear on the screens for these procedures. Read these warnings carefully before answering yes to the confirmations requested by the ServeRAID configuration program.

Backing Up Your Disk-Array Configuration

The ServeRAID adapter maintains a record of the disk-array configuration information in its nonvolatile RAM (NVRAM) and electrically erasable programmable read-only memory (EEPROM) module. The disk-array configuration is vital information. To protect this information, back up the information to diskette as soon as you have completed your tasks. You need a blank, 3.5-inch formatted diskette.

To back up the disk-array configuration information to diskette:

1. Label a blank diskette “Disk Array Configuration Backup” and date it.

2. Start the ServeRAID configuration program (refer to “Starting the Configuration Program” on page 25).

3. Select Advanced Functions from the Main Menu and press Enter.

4. Select Backup config. to diskette and press Enter.

5. Remove the ServeRAID configuration diskette from the drive and insert the blank diskette.

6. Follow the instructions on the screen.

64 PC Server 330 User's Handbook

Restoring the Disk-Array Configuration

To restore the disk-array configuration information in the ServeRAID adapter, use the ServeRAID Adapter Configuration Diskette and an up-to-date Disk Array Configuration Backup diskette.

Note: Because dynamic changes in the configuration of your disk

array occur due to hot-spare drive replacement or other drive maintenance activity, the configuration backup information on the diskette might be different from that stored in the adapter. Therefore, it is important that you back up the disk-array configuration information frequently, to keep the backup information on the diskette current.

Chapter 2. Configuring Your Disk Arrays 65

To restore the ServeRAID configuration information:

1. Start the ServeRAID configuration program (refer to “Starting the Configuration Program” on page 25).

2. Select Advanced Functions from the Main Menu and press Enter.

3. Select Restore config. from diskette and press Enter.

4. Enter the file name of the backed-up configuration in the box at the bottom of the screen and press Enter.

5. The Confirm pop-up window appears.

6. Select Yes to restore the configuration information. Select No to return to the previous menu.

7. Press Esc to return to the Main Menu.

Changing the Write Policy

When you configure a logical drive, the ServeRAID adapter sets the write policy to write-through (WT) mode, where the completion status is sent after the data is written to the hard disk drive. Under certain workloads, you can improve performance by changing this write policy to write-back (WB) mode, where the completion status is sent after the data is copied to cache memory, but before the data is actually written to the storage device.

Although you might gain performance with write-back mode, it creates a greater risk of losing data due to a power failure. This is because the system gets a completion status message when the data reaches cache memory, but before data is actually written to the hard disk drive.

If you change the write policy to write-back, wait at least 10 seconds after your last operation before you turn off your system. It takes that long for the system to move the data from the cache memory to the storage device. Failure to follow this practice can result in lost data.

66 PC Server 330 User's Handbook

To change the write policy:

1. Start the ServeRAID configuration program (refer to “Starting the Configuration Program” on page 25).

2. Select Advanced Functions from the Main Menu.

3. Select Change Write Policy from the Advanced Functions menu. The cursor will be active in the Logical Drive list.

5. Locate the Wrt pol field in the Logical Drive list. The write policy is shown as either write-through (WT), which

is the default setting, or write-back (WB).

6. Select the logical drive whose write policy you want to change. Attention: If you change the write policy to WB, wait at least

10 seconds after your last operation before you turn off your system. It takes that long for the system to move the data from the cache memory to the storage device. Failure to follow this practice can result in lost data.

7. Press Enter to change the write policy. Notice that WT changes to WB. You can press Enter to toggle

between WT and WB.

8. Press Esc. The Confirm pop-up window appears asking you to confirm your action.

The default settings are:

 Stripe Unit Size — 8 K

Attention: After the stripe-unit size is chosen and data is stored in the logical drives, the stripe-unit size cannot be changed without destroying data in the logical drives.

The stripe-unit size is the amount of data written on a given disk before writing on the next disk. To maximize the overall performance, choose the stripe-unit size such that the stripe-unit size is close to the size of the system I/O request. The default is set to 8 K data bytes. You can set the stripe-unit size to 8 K, 16 K, 32 K, or 64 K.

Chapter 2. Configuring Your Disk Arrays 69

– When the stripe-unit size is set to 8 K or 16 K, the

maximum number of drives in an array is 16.

– When the stripe-unit size is set to 32 K or 64 K, the

maximum number of drives in an array is eight.

 Rebuild Priority – High

Rebuild priority can be set to high, medium, or low. When the rebuild request is set to high, the rebuild I/O request gets high priority in the execution order.

When the rebuild request is set to medium in a heavily loaded system, the medium-priority rebuild can reduce the disk rebuild time at the expense of degraded handling of I/O requests.

When the rebuild priority is set to low in a moderate to heavily loaded system, low rebuild priority will increase the disk rebuild time but provides better system performance.

Note: You can change the rebuild priority without affecting

data in the logical drives.

 Unattended Mode – Off

You can enable the adapter to accept changes in the configuration without user input. Unattended mode is useful when the server operates remotely.

When Unattended Mode is Off, the program waits for user input.

When Unattended Mode is set to On and the hard disk drive is found in a location other than the one defined in the adapter configuration, the program pauses briefly for user input, then, rearranges the configuration information to correct the logical drive configuration. Unattended mode also clears any blocked drives.

70 PC Server 330 User's Handbook

 Read Ahead — On

Normally, the ServeRAID adapter transfers data from disk to its local cache in steps of stripe-unit size. This provides excellent overall performance when workloads tend to be sequential. However, if the workload is random and system I/O requests are smaller than the stripe-unit size, reading ahead to the end of the stripe unit will result in lower performance.

When read-ahead is set to Off, the size of data transfer from the disk to local cache is equal to the system I/O request size, and no read-ahead to the end of the stripe unit is performed.

Notes:

a. You can change the read-ahead setting without destroying

data in a logical drive.

b. When you save the configuration information on a diskette,

the RAID parameters are saved also.

Chapter 2. Configuring Your Disk Arrays 71

Unattended Mode of Operation

You can enable the adapter to accept changes in the configuration without user input. When this mode is enabled (refer to “Display/Change the ServeRAID Adapter Parameters” on page 79 for information), the adapter pauses briefly to permit a user to override the default action; then the adapter makes the necessary changes. Unattended mode, also clears any blocked drives. This mode is useful when the server operates remotely.

The adapter “chooses” an action that is equivalent to pressing one of the function keys in the following order.

F5: The server continues the startup operation after identifying the drive that is defunct. For example, a HSP drive failed to respond during POST. Startup continues without the HSP drive; its drive state will display as DHS.

F6: When a drive has been removed from the server, for example, for maintenance or security, and was returned, but in a different bay, the adapter adjusts the configuration to the drive's new location.

F7: An adapter with stored configuration information that does not match that of the configured drives present, import the configuration information from the drives. Refer to “ServeRAID Adapter Messages” on page 282 for more information.

72 PC Server 330 User's Handbook

RAID Subsystem Diagnostic Tests

The ServeRAID Subsystem Diagnostic program provides several utility programs that you can use to test the ServeRAID adapter and the devices connected to it.

To run the RAID diagnostic utility programs, do the following:

1. Start the ServeRAID configuration program (refer to “Starting the Configuration Program” on page 25).

2. Select Advanced Functions from the Main Menu.

3. Select IBM RAID Subsystem Diagnostic.

4. Select the diagnostic test that you want to run and press Enter.

 Run Adapter Self-Test runs diagnostic tests on the

ServeRAID adapter. Note: Restart your server after the self-test is complete.

 SCSI Device Self-Test runs diagnostic tests on the SCSI

devices attached to the ServeRAID adapter.

 Drive Media Test verifies that all sectors on the hard disk

drive can be accessed. The drive must be in the RDY or HSP state.

 Format Drive performs a low-level format on a hard disk

drive. For more information, see “Formatting Drives” on page 74.

5. Follow the instructions on the screen.

Chapter 2. Configuring Your Disk Arrays 73

Formatting Drives

You can perform a low-level format on drives with Ready (RDY) Empty (EMP), Standby (SBY), Standby Hot-Spare (SHS), or Hot-Spare (HSP) states.

Note: The Format Drive choice on the IBM ServeRAID Subsystems

Diagnostics menu provides a low-level format. If you install a new hard disk drive that requires a standard format, use the Format command provided by your operating system.

To perform a low-level format:

1. Start the ServeRAID configuration program (refer to “Starting the Configuration Program” on page 25).

2. Select Advanced Functions from the Main Menu and press Enter.

3. Select IBM RAID Subsystem Diagnostics from the Advanced Functions menu.

Attention: A low-level format erases all data and programs from the hard disk drive. Before proceeding, back up any data and programs that you want to save.

4. Select Format Drive and press Enter. You can perform a low-level format on more than one drive at a

time.

Note: If formatting is interrupted, the state of the drive being

formatted might appear as Empty (EMP) on the ServeRAID configuration screen in the Bay/Array selection list. Select the drive and format it again.

74 PC Server 330 User's Handbook

Resetting the Adapter Configuration

The RAID configuration information stored in the adapter's NVRAM is critical to the reliable operation of the disk array. Therefore, to protect the integrity of the configuration information, the configuration information is also stored in the adapter EEPROM and on each hard disk drive in a RBL or ONL state defined in the adapter NVRAM configuration. Each time the configuration information is changed, all corresponding copies are updated.

During POST, if the configuration information in the adapter's NVRAM, EEPROM, or configured hard disk drives does not match, an error message appears. (Refer to “ServeRAID Adapter POST and Setup Messages” on page 282 for more information.)

The Init/View Synchronize Configuration menu enables you to view or reset parameters.
