General checkout

The server diagnostic programs are stored in upgradable read-only memory (ROM) on the system board. These programs are the primary method of testing the major components of the server: the system board, Ethernet controller, video controller, RAM, keyboard, mouse (pointing device), diskette drive, serial port, and parallel port. You can also use them to test some external devices. See “Diagnostic programs” on page 11.

Also, if you cannot determine whether a problem is caused by the hardware or by the software, you can run the diagnostic programs to confirm that the hardware is working properly.

When you run the diagnostic programs, a single problem might cause several error messages. When this occurs, work to correct the cause of the first error message. After the cause of the first error message is corrected, the other error messages might not occur the next time you run the test.

A failed system might be part of a shared DASD cluster (two or more systems sharing the same external storage device(s)). Prior to running diagnostics, verify that the failing system is not part of a shared DASD cluster.

A system might be part of a cluster if:

 The customer identifies the system as part of a

cluster.

 One or more external storage units are attached to

the system and at least one of the attached storage

units is additionally attached to another system or

unidentifiable source.

 One or more systems are located near the failing

system.

If the failing system is suspect to be part of a shared DASD cluster, all diagnostic tests can be run except diagnostic tests which tests the storage unit (DASD residing in the storage unit) or the storage adapter attached to the storage unit.

8 Netfinity Server HMM

Notes

1. For systems that are part of a shared DASD cluster, run one test at a time in looped mode. Do not run all tests in looped mode, as this could enable the DASD diagnostic tests.

2. If multiple error codes are displayed, diagnose the first error code displayed.

3. If the computer hangs with a POST error, go to the “Symptom-to-FRU index” on page 285.

4. If the computer hangs and no error is displayed, go to “Undetermined problems” on page 325.

5. Power Supply problems, see “Symptom-to-FRU index” on page 285.

6. Safety information, see “Safety information” on page 340.

7. For intermittent problems, check the error log; see, “Error logs” on page 31.

001

IS THE SYSTEM PART OF A CLUSTER? Yes No

002

Go to Step 004.

003

Schedule maintenance with the customer. Shut down all systems related to the cluster. Run storage test.

004

– Power-off the computer and all external devices. – Check all cables and power cords. – Set all display controls to the middle position. – Power-on all external devices. – Power-on the computer. – Record any POST error messages displayed on the

screen. If an error is displayed, look up the first error in the “Symptom-to-FRU index” on page 285.

– Check the information LED panel System Error LED; if

on, see “Information panel system error LED” on page 290.

– Check the System Error Log. If an error was recorded

by the system, see “Symptom-to-FRU index” on page 285.

– Start the Diagnostic Programs. See “Running diagnostic

programs” on page 14.

– Check for the following responses:

1. One beep.

(Step 004 continues)

Netfinity 5500 M20 - Type 8662

004 (continued)

2. Readable instructions or the Main Menu.

DID YOU RECEIVE BOTH OF THE CORRECT RESPONSES? Yes No

005

Find the failure symptom in “Symptom-to-FRU index” on page 285. Or, use remote video mode to monitor and access POST or to look at the System Error Log. See “Using remote video mode to monitor and access POST” on page 58.

006

– Run the Diagnostic Programs. If necessary, refer to

“Running diagnostic programs” on page 14. If you receive an error, go to “Symptom-to-FRU index” on page 285. If the diagnostics completed successfully and you still suspect a problem, see “Undetermined problems” on page 325.

Note

A single problem might cause several error messages. When this occurs, work to correct the cause of the first error message. After the cause of the first error message is corrected, the other error messages might not occur the next time you run the test.

To run the Diagnostic Programs, see “Running diagnostic programs” on page 14.

For a list of error codes and messages, see “Symptom-to-FRU index” on page 285.

Power-on self-test (POST)

When you turn on the server, it performs a series of tests to check the operation of server components and some of the options installed in the server. This series of tests is called the power-on self-test or POST.

POST does the following:

 Checks the operation of some basic system board

operations

 Checks the memory  Compares the current server configuration with the

stored server configuration information

Netfinity 5500 M20 - Type 8662

 Configures PCI adapters  Starts the video operation  Verifies that drives (such as the diskette, CD-ROM,

and hard disk drives) are connected properly

If you have a power-on password or administrator password set, you must type the password and press Enter, when prompted, before POST will continue.

While the memory is being tested, the amount of available memory appears on the screen. These numbers advance as the server progresses through POST and the final number that appears on the screen represents the total amount of memory available. If POST finishes without detecting any problems, a single beep sounds, the first screen of the operating system or application program appears, and the System POST Complete (OK) light is illuminated on the information LED panel.

If POST detects a problem, more than one beep sounds and an error message appears on the screen.

Note

For a list of error codes and messages, see “Symptom-to-FRU index” on page 285.

POST beep codes

POST generates beep codes to indicate successful completion or the detection of a problem.

 One beep indicates the successful completion of

POST.

 More than one beep indicates that POST detected a

problem. For a list of error codes and messages, see “Symptom-to-FRU index” on page 285.

Error messages - descriptions

Error messages indicate that a problem exists; they are not intended to be used to identify a failing part. Troubleshooting and servicing of complex problems indicated by error messages should be performed by trained service personnel.

Hardware error messages that occur can be text, numeric, or both. Messages generated by the software generally are text messages, but they also can be numeric.

POST error messages:

POST error messages occur during startup when POST finds a problem with the hardware or detects a change in the hardware configuration. For a list of error codes and messages, see “Symptom-to-FRU index” on page 285.

Diagnostic error messages:

Diagnostic error messages occur when a test finds a problem with the server hardware. These error messages are alphanumeric and they are saved temporarily in the Test Log and logged in the System Error Log when diagnostics are run. For a list of error codes and messages, see “Symptom-to-FRU index” on page 285.

Software-generated error messages:

These messages occur if a problem or conflict is found by an application program, the operating system, or both. Messages are generally text messages, but they also can be numeric. For information about these error messages, refer to the documentation that comes with the software.

System error log

The System Error Log contains all error and warning messages issued during POST and all system status messages from the Netfinity Advanced System Management Processor. See “System error log” on page 31 for information about how to view the System Error Log.

Option diskettes

An optional device or adapter might come with an Option Diskette. Option Diskettes usually contain option-specific diagnostic test programs or configuration files.

If the optional device or adapter comes with an Option Diskette, follow the instructions that come with the option. Different instructions apply depending on whether the Option Diskette is startable or not.

Netfinity 5500 M20 - Type 8662

Configuration overview

You play a key role in how the server allocates resources to organize and interconnect hardware devices and software programs. This allocation process is referred to as

configuration.

server depend on the number and types of devices and programs that you install.

The server supports several types of adapters and SCSI devices. Because of this flexibility, you can choose from among many adapters and devices that comply with any of the following standards:

 Peripheral Component Interconnect (PCI)  Industry Standard Architecture (ISA)  Small Computer System Interface (SCSI)

In general, the greater the number and variety of hardware devices and software programs that you install in the server, the more you will have to interact with the server and the devices to correctly configure the system.

The server comes with the following hardware configuration utility programs:

 Configuration/Setup Utility

With the built-in Configuration/Setup Utility program, you can configure system board functions, such as serial and parallel port assignments; change interrupt request (IRQ) settings; and change the startup sequence for drives that you install. You also can use this utility program to set passwords for starting up the server and accessing the Configuration/Setup Utility program.

 ServeRAID

You can use ServeRAID programs to define and maintain the disk arrays. You can also use these programs to configure SCSI devices (such as hot-swap drives) that are attached to the ServeRAID controller on the system board. Refer to “ServeRAID system board controller” on page 66 for complete instructions.

Before installing a new device or program, read the documentation that comes with it. Reading the instructions helps you to determine the steps required for installation and configuration. The following actions are typically, but not always, required to configure the server.

1. Run the Configuration/Setup Utility program and record the current configuration settings.

2. Set jumpers or switches on the server system board. See “Changing jumper positions” on page 176 and

“System board jumpers” on page 280.

3. Set jumpers or switches on the device. See the device installation instructions.

The steps required to configure the

20 Netfinity Server HMM

4. Install the device in the server. See “Locations/Removals” on page 160. If you install an ISA adapter that is not a Plug and

Play device, select the Plug and Play choice on the main menu of the Configuration/Setup Utility program to assign the ISA legacy resources. See “Plug and Play” on page 31 for more information.

5. Install software programs. See the installation instructions that come with the

software.

6. Resolve configuration conflicts. See “Resolving configuration conflicts” on page 33.

Configuration/Setup Utility program

For most configurations, the server will operate using the default system settings. You need to change the settings only to resolve configuration conflicts or to enable or change device functions (for example, defining diskette types, and so on).

When you want or need to change the default settings, the Configuration/Setup Utility program provides a convenient way to display and change the settings.

After you run and exit from the Configuration/Setup Utility program, configuration information is stored in nonvolatile random-access memory (NVRAM). While the server is off, the configuration information remains available for the next system startup.

Always run the Configuration/Setup Utility program if you add, remove, or relocate any hardware option, or if you receive an error message instructing you to do so. Review this information and the information that comes with the option before making changes.

Finally, should you ever need to restore the default configuration, the default configuration can be loaded by starting the system and then pressing the reset button four times, waiting 15 seconds between each press. Once the configuration has reset to the default, it must be saved in Setup to be stored in CMOS.

To start the Configuration/Setup Utility program:

1. Turn on the server and watch the screen.

2. When the message Press F1 for Configuration/Setup appears, press F1.

Netfinity 5500 M20 - Type 8662

Note

If you enter the power-on password and an administrator (supervisor-level) password is also set, a limited version of the menu appears. To see the full menu, you must restart the server and enter the administrator password when you are prompted to enter a password. See “System security” on page 25 for additional information.

The Configuration/Setup Utility program main menu appears. For information about the menu, see “Configuration/Setup Utility main menu.”

Configuring options

Before installing a new device or program, read the documentation that comes with it. Reading the instructions helps you to determine the steps that are required for installation and configuration. The following list provides a preview of the actions that might be required to configure the server.

1. Run the Configuration/Setup Utility program and record the current configuration settings.

See “Configuration/Setup Utility program” on page 21.

2. Set jumpers or switches on the server system board. See “Changing jumper positions” on page 176 and

“System board jumpers” on page 280.

3. Set jumpers or switches on the device. See the instructions that came with the adapter.

4. Install the adapter in the server. See “Adapters” on page 161.

5. Install software programs. See the installation instructions that came with the

software.

6. Resolve configuration conflicts. See “Resolving configuration conflicts” on page 33.

32 Netfinity Server HMM

Configuring ISA and PCI adapters

You cannot assign an ISA adapter to the same interrupt that you have assigned to a PCI adapter. This is because the Netfinity 5500 M20 does not support interrupt sharing among PCI and ISA adapters.

If a situation occurs where you need an additional interrupt, you can use an interrupt from another function that you might not need, such as COM2 (Interrupt 3).

To configure ISA adapters, select Plug and Play and follow the instructions on the screen. See “Plug and Play” on page 31 and “Plug and Play technology” on page 164 for additional information.

PCI devices automatically communicate with the server configuration information. This usually results in automatic configuration of a PCI device. If a conflict does occur, see “Resolving configuration conflicts.”

Multiple-function PCI adapters use more than one interrupt. When you install one of these adapters, review the IRQ assignments in the Configuration/Setup Utility programs (see “PCI routing” on page 23). Verify that the IRQ assignments are correct.

The Netfinity 5500 M20 uses a rotational interrupt technique to configure PCI adapters. This technique enables you to install a variety of PCI adapters that currently do not support sharing of PCI interrupts.

Resolving configuration conflicts

The resources used by the server consist of IRQs, DMA, I/O ports addresses, and memory. This information is useful when a resource configuration conflict occurs.

Conflicts in the configuration occur if:

 A device is installed that requires the same resource

as another device. (For example, a conflict occurs when two adapters try to write to the same address space.)

 A device resource is changed (for example, changing

jumper settings).

 A device function is changed (for example, assigning

COM1

to two serial ports).

 A software program is installed that requires the same

resource as a hardware device.

The steps required to resolve a configuration error are determined by the number and variety of hardware devices and software programs that you install. If a hardware configuration error is detected, a message appears after the server completes POST and before the operating system is loaded. You can bypass the error by pressing Esc while the error message is displayed.

Netfinity 5500 M20 - Type 8662

configuration error

The Configuration/Setup Utility program configures the system hardware and PCI IRQs. The program does not consider the requirements of the operating system or the application programs. See “Resolving software configuration conflicts” on page 34 for additional information.

Resolving hardware configuration conflicts:

Use the following information to help resolve hardware configuration conflicts:

1. Run the Configuration/Setup Utility program to view and change resources used by the system board functions and the installed options. Record the current settings before making any changes. (See “Configuration/Setup Utility program” on page 21 for instructions.)

2. Determine which adapter or device is causing the conflict.

3. Change adapter jumpers or switches. Some devices use jumpers and switches to define the system resources that the devices need. If the settings are incorrect or set to use a resource that cannot be shared, a conflict occurs and the device will remain deactivated by the configuration program.

4. Remove the device or adapter. Some configurations are not supported. If you must remove an adapter, see “Adapters” on page 161.

Resolving software configuration conflicts:

The memory-address space and IRQs used by some hardware options might conflict with addresses defined for use through application programs or the expanded memory specification (EMS). (EMS is used only with DOS.)

If a conflict exists, one or more of the following conditions might exist:

 The system cannot load the operating system.  The system does not work.  An application program does not operate, or it returns

an error.

 Screen messages indicate a conflict exists.

To resolve conflicts, you can change the software or hardware configuration.

Note

Start the Configuration/Setup Utility program to view the addresses used by the system board functions. (See “Configuration/Setup Utility program” on page 21 for instructions.)

34 Netfinity Server HMM

The best way to resolve memory-address conflicts is to change the addresses used by the application program or the device driver. You can use the Configuration/Setup Utility program to change addresses.

If a device driver is causing a memory-address conflict, refer to the operating system documentation or the documentation that comes with the device drivers.

Configuring the ethernet controller

The Netfinity 5500 M20 server comes with an Ethernet controller on the system board. The Ethernet controller provides 10BASE-T and 100BASE-TX support through the RJ-45 connector on the back of the server. When you connect the server to the network, the Ethernet controller automatically detects the data-transfer rate (10 Mbps or 100 Mbps) on the network and then sets the controller to operate at the appropriate rate. That is, the Ethernet controller will adjust to the network data rate, whether the data rate is standard Ethernet (10BASE-T), Fast Ethernet (100BASE-TX), half duplex (HDX), or full duplex (FDX). This process is also known as auto-negotiation. This auto-negotiation occurs without requiring software intervention. The controller supports half-duplex (HDX) and full-duplex (FDX) modes at both speeds.

However, auto-negotiation works only if the hub or switch at the other end of the network also supports auto-negotiation. If the hub or switch does not support auto-negotiation, the speed (10 Mbps or 100 Mbps) will still be detected correctly, but half-duplex mode will always be selected. A full-duplex switch that does not support auto-negotiation will not attach to the Netfinity 5500 M20 server in full-duplex mode. In this case, if you want the network to operate in full-duplex mode, you must manually override the settings to obtain a full-duplex connection. Refer to the Ethernet documentation for additional information.

Attention

 The 10BASE-T Ethernet and the 100BASE-TX

Fast Ethernet cabling in the network must be Category 5 or higher to meet various standards, including electromagnetic compatibility.

 You must install a device driver to enable the

operating system to address the Ethernet controller. Use ServerGuide to install this device driver. Refer to the ServerGuide package for instructions on installing device drivers.

Fast Ethernet operates at a data rate of 100 Mbps; that is, ten times faster than standard Ethernet. However, except for the different operating speeds, Fast Ethernet and standard Ethernet are structurally identical. Applications

Netfinity 5500 M20 - Type 8662 35

and protocols that are currently installed on a standard Ethernet system can be seamlessly migrated to a Fast Ethernet system. (In a very small number of cases, minor tuning might be required to adjust the application to the faster response time of a Fast Ethernet system.) Because of the equivalence of the two types of Ethernet, mixed Ethernet and Fast Ethernet systems also can be designed and implemented.

The bandwidth required at each workstation connected to a server is generally far less than the bandwidth required at the server. This is because the server might have to handle the bandwidth of multiple workstations at the same time. A cost-effective solution to the bandwidth requirements of this type of system is a mixed Ethernet and Fast Ethernet network. This mixed network consists of standard Ethernet connections at the workstations and Fast Ethernet connections at the servers.

The Ethernet controller is a PCI device, and is therefore a Plug and Play device. You do not have to set any jumpers or configure the controller for the operating system before you use the Ethernet controller.

The Ethernet controller supports the auto-detection mode only. When you install the device drivers and configure the Ethernet controller for use with the operating system, do not select the 10BASE-T mode. To ensure proper operation of the controller, always select the default parameters provided.

Notes

The Ethernet controller supports the operating systems that the server supports. To find out which operating systems the server supports, go to the following World Wide Web address:

http://www.ibm.com/pc/us/netfinity/

If you need additional Ethernet connections, you can install an Ethernet adapter, such as an IBM 10/100 Ethernet adapter. Review the network adapter documentation for any additional configuration requirements.

Note

If you are installing an IBM 10/100 Ethernet adapter, be sure to run the Ethernet diagnostics and record the server's Ethernet configuration information before you install the adapter.

Ethernet cable specifications

The Ethernet controller on the system board provides 10BASE-T and 100BASE-TX support through the RJ-45 connector on the back of the server. When you connect the server to the network, the Ethernet controller

36 Netfinity Server HMM

automatically detects the data-transfer rate (10 Mbps or 100 Mbps) on the network and then sets the controller to operate at the appropriate rate.

The following information describes the specifications for the unshielded twisted-pair (UTP) cable that can be used to connect the server to an IEEE Standard 802.3 network.

To connect the server 10BASE-T or 100BASE-TX port to a 10BASE-T or 100BASE-TX port on a repeater, use a UTP cable with RJ-45 connectors at both ends. An EIA/TIA-568 Category 5 cable must be used for 10BASE-T and 100BASE-TX.

Attention

The 10BASE-T Ethernet and the 100BASE-TX Fast Ethernet cabling in the network must be Category 5 or higher to meet various standards, including electromagnetic compatibility.

The cables used in 10BASE-T or 100BASE-TX link segments do not require grounding. However, all devices connected to the cables must be grounded.

Connect the appropriate type of UTP cable to the repeater.

 If the port on the repeater is a crossover port (also

called an MDI-X port), use a UTP cable that is wired as a straight-through cable.

 If the port on the repeater is not a crossover port

(also known as an MDI port), use a UTP cable that is wired as a crossover cable.

Do not use telephone extension cables to connect the server to a repeater. The wire pairs in those cables are not twisted, and the cables do not meet other requirements for use in a 10BASE-T or 100BASE-TX network. You can identify telephone extension cables by their flat and thin appearance. UTP cables are rounder and thicker than telephone extension cables.

Table 1 on page 38 describes the specifications for UTP cables used in 10BASE-T and 100BASE-TX link segments. Cables for these link segments must be certified as EIA/TIA-568 Category 5.

, the hub has an X port.

If the Ethernet activity light is off:

a. Make sure that the hub and network are

operating, and that the correct device drivers are loaded.

b. There might be a defective Ethernet connector or

cable, or a problem with the hub.

3. Make sure that you are using the correct device drivers that come with the server.

4. Check for operating system-specific causes for the problem.

5. Test the Ethernet controller or adapter.

Netfinity 5500 M20 - Type 8662 39

How you test the Ethernet controller or adapter depends on which operating system is being used (see “Configuring the ethernet controller” on page 35).

Failover for redundant Ethernet

The Netfinity 5500 M20 has an integrated Ethernet controller. The IBM Netfinity 10/100 Fault Tolerant Adapter is an optional redundant network interface card (NIC adapter) that you can install in the server. If you install this NIC adapter and connect it to the same logical segment as the primary Ethernet controller, you can configure the server to support a can configure either the integrated Ethernet controller or the NIC adapter as the primary Ethernet controller. In failover mode, if the primary Ethernet controller detects a link failure, all Ethernet traffic associated with it is switched to the redundant (secondary) controller. This switching occurs without any user intervention. Applications with active sessions do not experience any data loss. When the primary link is restored to an operational state, the Ethernet traffic automatically switches back to the primary Ethernet controller.

Note that only one controller in the redundant pair is active at any given time. For example, if the primary Ethernet controller is active, then the secondary Ethernet controller cannot be used for any other network operation.

Note

The operating system determines the maximum number of IBM Netfinity 10/100 Fault Tolerant Adapters that you can install in the server. See the documentation that comes with the adapter for more information.

failover

function. You

Special considerations when combining failover and hot-plug functions:

If the operating system supports hot-plug PCI adapters and the optional redundant NIC adapter is installed in a hot-plug PCI slot, you can replace the NIC adapter without powering off the server — even if it is the primary Ethernet controller. Disconnecting the Ethernet cable from the primary Ethernet controller will cause the Ethernet traffic to be automatically switched to the secondary Ethernet controller. This can be very useful when a network problem is caused by faulty adapter hardware or when you want to upgrade the primary adapter hardware.

40 Netfinity Server HMM

Configuring for failover:

The failover feature currently is supported by OS/2, Windows NT, and IntraNetWare. The setup required for each operating system follows.

OS/2

1. Add the redundant NIC adapter according to the instructions provided with the adapter and in “Adapters” on page 161.

2. Use the ServerGuide CDs to install the AMD PCNet Ethernet Family adapter device driver.

3. Using the MPTS Utility program, select the driver from the list and select the Edit button.

Note

Only one driver instance needs to be loaded for each redundant pair of Ethernet controllers.

4. Change the PermaNet Server Feature keyword to TRUE and specify the Primary and Standby slots that contain the redundant pair. Refer to “System board component locations” on page 279 for the locations and slot numbers of the PCI slots. The integrated controller is located in slot E (PCI primary bus 0, slot

14).

5. To enable the writing of messages to the IBMCOM\LANTRAN.LOG file when a failover occurs:

a. Copy the file PCNETOS2.EXE from the root

directory of the diskette created using the ServerGuide CDs to the hard disk drive.

b. Add the following statement to the CONFIG.SYS

file:

Run=d:\path\PCNETOS2.EXE

where d and which you copied PCNETOS2.EXE.

6. Restart the server.

6. Select the adapter pair you want and then select OK. Note that the integrated Ethernet controller is located at PCI primary bus 0, slot 14.

7. Select Close to exit from the Network setup. When you restart the server, the failover function will

be in effect.

If a failover occurs, a message is written to the Windows NT Event Viewer log. If the DMI instrumentation code for the integrated Ethernet controller is active (PCNET.EXE was run), a pop-up message is generated also.

IntraNetWare

1. Add the redundant NIC adapter according to the instructions provided with the adapter and in “Adapters” on page 161.

2. Load the device driver by using the following command:

LOAD d:\path\PCNTNW.LAN PRIMARY=x SECONDARY=y

where d and driver is located, and x and y are the PCI slot numbers where the redundant pair is located.

The slot number associated with the integrated Ethernet controller can vary depending upon the configuration of the server. To determine the slot number, load the driver with no parameters. The driver will display the available slot numbers. The slot number that is greater than 10000 will be the slot number of integrated Ethernet controller. When the slot number of the integrated Ethernet controller is determined, reload the driver with the appropriate parameters.

3. When the driver is loaded, bind it to a protocol stack.

Light path diagnostics

The light path diagnostics built into the server allow you to quickly identify the type of system error that occurred. The server is designed so that any LEDs that are illuminated remain illuminated when the server shuts down as long as the ac power source is good and the power supplies can supply +5V dc current to the server. This feature helps you isolate the problem if an error causes the server to shut down.

The light path diagnostics begin with the System Error LED on the information LED panel. (See the illustration in “Information LED panel” on page 205.) When this light is illuminated, use the following information to isolate the problem.

Netfinity Advanced System Management Processor

The following information is about the Netfinity Advanced System Management Processor that is integrated in the Netfinity 5500 M20. It also describes how to access the Netfinity Advanced System Management Processor without Netfinity Manager.

Note

To use all of the functions of the Netfinity Advanced System Management Processor, you must install the Advanced System Management service for Netfinity Manager. You also will need a user-provided modem attached to serial port A to use the remote functions. Refer to “Serial ports” on page 189 for information about serial port A.

The Advanced System Management service gives you the ability to configure and monitor many features of the server's Netfinity Advanced System Management Processor. You can connect to, and directly access and control, the Netfinity Advanced System Management Processor of a remote system. With the Advanced System Management service you can configure Advanced System Management service events (such as POST, loader, and operating system timeouts; and critical temperature and

52 Netfinity Server HMM

voltage failures). If any of these events occur, the Advanced System Management service can be configured to automatically forward a Netfinity alert in one of three ways:

 Alert forwarded to another Netfinity system  Alert forwarded to a standard numeric pager  Alert forwarded to an alphanumeric pager

In addition, with the Advanced System Management service you can remotely monitor, record, and replay all textual data generated by a remote system during POST. While monitoring a remote system during POST, you can enter key commands on the keyboard that will then be relayed to the remote system.

The Netfinity Manager software is included in the ServerGuide package. Refer to the documentation that comes with ServerGuide for information on how to install the Netfinity Manager software. Then, refer to the online Netfinity documentation or the online

Management Service for Netfinity Manager User’s Guide

for information on using the Netfinity Advanced System Management Processor.

(built into the Netfinity 5500 M20)

 Netfinity Manager or Client Services for Netfinity

Manager, version 5.10.4 or later

 2 MB of available hard disk drive space

Accessing the Netfinity Advanced System Management Processor without Netfinity Manager:

If for some reason you are unable to use Netfinity Manager to access and manage the Netfinity Advanced System Management Processor, you can use a terminal program and a modem to connect directly to the Netfinity Advanced System Management Processor. This modem should be connected to management port C. (See “Management port C” on page 190.) When connected, you will be able to access a variety of monitor, configuration, and error log data. You can also power the remote (Netfinity 5500 M20) system on or off, shutdown and restart the server, and initiate remote video mode on the Netfinity Advanced System Management Processor. Remote video mode enables you to remotely monitor all textual output generated during POST. All POST data will be displayed

Netfinity 5500 M20 - Type 8662

in the terminal program window as the remote system completes POST. While you are monitoring POST on the remote system, all local (terminal program) keystrokes are relayed automatically to the remote system, enabling you to use POST utilities (such as system configuration, RAID Mini-Configuration program, and diagnostic programs) that can be accessed during POST.

To use a terminal program to establish a connection with the Netfinity Advanced System Management Processor:

1. Use a terminal program to establish a connection with the Netfinity Advanced System Management Processor modem. The modem settings you should use are:

Understanding RAID technology

RAID is the technology of grouping several hard disk drives in a computer into an one or more logical drives. Each the operating system as a single drive. This grouping technique greatly enhances logical-drive capacity and performance beyond the physical limitations of a single hard disk drive.

When multiple physical hard disk drives are grouped into a logical drive, the ServeRAID controller can transfer data in parallel from the multiple drives in the array. This parallel transfer yields data-transfer rates that are many times higher than with nonarrayed drives. This increased speed makes the system better able to meet the amount of work in a given amount of time) or productivity needs of the multiple-user network environment.

The ability to respond to multiple data requests provides not only an impressive increase in throughput, but also a decrease in response time. The combination of parallel transfers and simultaneous responses to multiple requests allows disk arrays to provide a high level of performance in network environments.

Interleave depth and stripe-unit size:

With RAID technology, data is hard disk drives. This data-distribution scheme complements the way the operating system requests data.

The granularity at which data from one file is stored on one drive of the array before subsequent data is stored on the next drive of the array is called the

You can control the interleave depth and maximize the performance of a ServeRAID controller by setting a stripe-unit size that is close to the size of the system I/O requests. You can set the stripe-unit size to 8 KB, 16 KB, 32 KB, or 64 KB. For example, performance in transaction-based environments, which typically involve large blocks of data, might be optimal when the stripe-unit size is set to 32 KB or 64 KB; however, performance in file and print environments, which typically involve multiple small blocks of data, might be optimal when the stripe-unit size is set to 8 KB or 16 KB.

The collection, in logical order of these stripe units, from the first drive of the array to the last drive of the array, is

Netfinity 5500 M20 - Type 8662

The ServeRAID adapters and controllers support RAID level-0, RAID level-1, Enhanced RAID level-1, and RAID level-5.

RAID level-0:

RAID level-0 stripes the data across all the drives in the array. This offers substantial speed enhancement, but provides for no data redundancy. RAID level-0 provides the largest capacity of the RAID levels offered, because no room is taken up for redundant data or data-parity storage.

The following illustration shows data arranged in an array of three hard disk drives defined as one RAID level-0 logical drive. Notice that the data is striped across all the drives in the array, but no copies of the data or parity information is stored.

Stripe 1 Block 1 Block 2 Block 3 Stripe 2 Block 4 Block 5 Block 6 Stripe 3 Block 7 Block 8 Block 9

A hard disk failure within the array results in loss of data in the logical drive assigned RAID level-0, but

logical drive

. If there are logical drives assigned RAID

only in that

level-1 or level-5 in the same array, they will not lose data.

Note

The ServeRAID controller automatically assigns RAID level-0 to all logical drives in an array containing only one hard disk drive.

When you replace a failed drive, the ServeRAID controller can rebuild all the RAID level-1 and RAID level-5 logical drives automatically onto the replacement hard disk drive. However, any data stored in a failed RAID level-0 logical drive is lost.

Though the risk of data loss is present, you might want to assign RAID level-0 to one of the logical drives to take advantage of the speed offered with this RAID level. You could use this logical drive to enter data that is backed up each day and for which safety is not of primary importance, that is, data that can be easily re-created. You also might want to use a RAID level-0 logical drive when the work being done requires maximum capacity.

RAID level-1:

RAID level-1 provides 100% data redundancy and requires two hard disk drives. With RAID level-1, the first half of a stripe is the original data; the second half of a stripe is a

mirror

(copy) of the data, but

written to another drive. Because the data is mirrored, the capacity of the logical

drive when assigned RAID level-1 is 50% of the physical capacity of the two hard disk drives in the array.

The following illustration shows data arranged in an array of two hard disk drives defined as one RAID level-1 logical drive. Notice that the data on Drive B is a mirror copy of the data on Drive A.

Drive A

Data Stripe 1 Block 1 Mirror Stripe

Data Stripe 2 Block 2 Mirror Stripe

Data Stripe 3 Block 3 Mirror Stripe

Drive B

Block 1

Block 2

Block 3

If one of the hard disk drives fails, the ServeRAID controller switches read and write requests to the remaining functional drive in the array.

Enhanced RAID level-1:

When you group more than two physical drives into an array and select RAID level-1, the ServeRAID controller automatically assigns the IBM Enhanced RAID level-1 to the array.

The Enhanced RAID level-1 combines mirroring with data striping. This RAID level stripes data and copies of the data across all the drives in the array. As with the standard RAID level-1, the data is mirrored, and the capacity of the logical drive is 50% of the physical capacity of the grouping of hard disk drives in the array.

The Enhanced RAID level-1 requires a minimum of three drives and, depending upon the stripe-unit size, supports a maximum of eight or 16 drives.

The following illustration shows data arranged in an array with three hard disk drives. The logical drive is assigned the Enhanced RAID level-1. Notice that the first stripe is the data stripe and the second stripe is the mirror (copy) of the first data stripe, but shifted one drive.

RAID level-5:

Block 3 Block 1 Block 2

Block 6 Block 4 Block 5

RAID level-5 requires a minimum of three

hard disk drives. This RAID level stripes data and parity across all drives in the array. When an array is assigned RAID level-5, the capacity of the logical drive is reduced by one drive (for data-parity storage).

RAID level-5 is generally the most desirable choice, because it offers both data protection and increased throughput. RAID level-5 gives higher capacity than RAID level-1, but RAID level-1 offers better performance.

The following illustration shows data arranged in an array with three hard disk drives. The logical drive is assigned RAID level-5. Notice that the storage of the data parity also is striped, and it shifts from drive to drive.

2. Continue with one of the following:  “Configuration mode”

 “Information mode” on page 78

Configuration mode:

You can use the Configuration mode to create up to eight independent disk arrays for each ServeRAID controller. The Configuration mode provides two configuration paths:

Express Configuration

and

Custom Configuration

Netfinity 5500 M20 - Type 8662

Express Configuration provides a quick and easy path for you to automatically configure the ServeRAID controller. This choice creates the most efficient ServeRAID configuration based on the number and capacity of the Ready drives available in the system. If four or more Ready drives of the same capacity are available, this choice also will define a

hot-spare drive

for the ServeRAID adapter or controller. A hot-spare drive is a physical drive that is defined for automatic use when a similar drive fails.

The Express Configuration choice groups up to 16 Ready drives of the same capacity into one disk array and defines one logical drive for each array. This choice defines the size of the logical drive, based on the amount of free space available, and it assigns the highest RAID level possible, based on the number of physical drives available.

For example, if the server contains one 1024 MB Ready drive, two 2150 MB Ready drives, and four 4300 MB Ready drives, Express Configuration will create three arrays and one hot-spare drive as follows:

Array A: The total capacity of this array is 1024 MB

(1 x 1024 MB) and it contains one 1024 MB RAID level-0 logical drive.

Array B: The total capacity of this array is 4300 MB

(2 x 2150 MB) and it contains one 2150 MB RAID level-1 logical drive.

Array C: The total capacity of this array is 12900 MB

(3 x 4300 MB) and it contains one 8600 MB RAID level-5 logical drive.

Hot Spare: Express Configuration defines one of the four

4300 MB drives as a hot-spare drive, as follows:

 When there are four or more Ready

drives of the same capacity, Express Configuration groups three of the drives into one array (as in Array C) and defines one of the drives as a hot spare.

 A hot-spare drive must be of equal or

greater capacity than the drive that it is intended to replace. In this configuration, the 4300 MB drive can replace any failed drives in Array B or Array C.

Using Express Configuration

To use the Express Configuration path:

1. Select the ServeRAID controller that you want to configure in the Main Tree.

2. Select the Express Configuration radio button.

3. Select the Next button.

4. Review the information that appears on the Configuration Summary screen.

74 Netfinity Server HMM

Notes

1. Some operating systems have size limitations for logical drives. Before you save the configuration, you might want to verify that the size of the logical drive is appropriate for the operating system. See the operating system documentation for more detailed information.

2. To change the configuration, select a Modify icon button.

5. Select the Apply button to accept and save the configuration.

6. If you have not already done so, install the operating system. See the server documentation or the documentation provided with the operating system for more information.

After you install the operating system, see “ServeRAID device drivers and utility programs (installation)” on page 130 (or see the installation instructions provided with the server) for information about installing the ServeRAID device drivers and utility programs.

Learning about custom configuration:

The Custom Configuration path allows you to manually configure the ServeRAID subsystem. Using this path, you can select the drives that you want to include in each array, define the number and size of the logical drives for each array, and select the drives that you want to use as hot spares.

Before you select the Custom Configuration path, consider the following:

 If you are not familiar with the IBM implementation of

RAID technology, you might want to review the information provided in “Understanding RAID technology” on page 67 before you begin.

 Each ServeRAID controller supports a maximum of

eight arrays.

 Each ServeRAID controller supports a maximum of

eight logical drives. When you create an array, you group hard disk drives

into one storage area. You can define this storage area as a single into several logical drives. Each logical drive appears to the operating system as a single physical hard disk drive.

If you have only one array, you can define it as a single logical drive, or you can divide it into several logical drives. Typically, the first logical drive defined on the first ServeRAID adapter or controller found by

logical

drive, or you can subdivide it

Netfinity 5500 M20 - Type 8662

the basic input/output system (BIOS) during startup will be the startup (boot) drive.

If you have two or more arrays, each array can be one logical drive, or you can divide each array into multiple logical drives, as long as the total number of logical drives for all of the arrays does not exceed eight.

Note

Independent of the RAID logical drives, most operating systems allow you to partition the logical drives further.

 The optimal way to create arrays is to use hard disk

drives that have the same capacity. Hard disk drive capacities influence the way you

create arrays. Drives in an array can be of different capacities (1 GB

, or 2 GB, for example), but RAID controllers treat them as if they all have the capacity of the

smallest

disk drive.

For example, if you group three 1 GB drives and one 2 GB drive into an array, the total capacity of the array is 1 GB times 4, or 4 GB, not the 5 GB physically available. Similarly, if you group three 2 GB drives and one 1 GB drive into an array, the total capacity of that array is 4 GB, not the 7 GB physically available.

 A hot-spare drive is a disk drive that is defined for

automatic use in the event of a drive failure. The hot-spare drive must be of equal or greater capacity than the drive that it is intended to replace. If a physical drive fails and it is part of a RAID level-1 or RAID level-5 logical drive, the ServeRAID controller automatically starts to rebuild the data on the hot-spare drive.

 You can include a maximum of 16 physical drives in

an array when the stripe-unit size is set to 8 KB (the default setting) or 16KB, and you can include a maximum of 8 physical drives in an array when the stripe-unit size is set to 32KB or 64KB. (See “Interleave depth and stripe-unit size” on page 67 and page 90 for more information.)

Using custom configuration:

To use the Custom Configuration path:

1. Select the ServeRAID controller that you want to configure in the Main Tree.

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

76 Netfinity Server HMM

2. Select the Custom Configuration radio button.

3. Select the Next button.

4. Using the right mouse button, select the drive or SCSI Channel icons in the Main Tree to select the drives that you want to add to the arrays, delete from the arrays, or define as hot-spare drives; then, select a choice from the pop-up list.

Drag the drive or SCSI Channel icon from the Main Tree and drop it on the Array or Hot-Spare Drive icon in the Main Panel on the right. If you change your mind, you can drag the icons back to the Main Tree to remove them from the configuration.

5. After you select the data drives for the arrays and define the hot-spare drives, select the Next button.

If you change your mind, you can:

 Remove a specific drive from a newly defined

array or delete an entire newly defined array. To do this, select the Back button, use the right mouse button to select the specific drive or Array icon in the Main Panel on the right, and then select Remove from New Array or Delete New Array.

 Remove a specific hot-spare drive or all newly

defined hot-spare drives. To do this, select the Back button, use the right mouse button to select the Hot-Spare Drive icon in the Main Panel on the right, and then select Remove New

Hot-Spare Drive or Remove All New Hot-Spare Drives.

6. Select a RAID level for the logical drive from the RAID pull-down menu in the Main Panel. (See “Supported RAID levels” on page 67 for descriptions of the supported levels.)

7. Move the sliding bar in the Main Panel from right to left to allot data and parity space for the logical drive.

Notes

1. You can define from one to eight logical drives.

2. Some operating systems have size limitations for logical drives. Before you save the configuration, you might want to verify that the size of the logical drive is appropriate for the operating system. See the operating system documentation for more detailed information.

3. Typically, the first logical drive defined on the first ServeRAID adapter or controller found by system BIOS during startup will be the startup (boot) drive.

Netfinity 5500 M20 - Type 8662 77

8. If free space is available and you want to define another logical drive, click on the Add Logical Drive button in the Main Panel.

9. Repeat steps 6, 7, and 8 for each logical drive that you want to define; then, continue with step 10.

10. Select the Next button.

11. Review the information that appears on the Configuration Summary screen.

Note

To change the configuration, select a Modify icon button.

12. Select the Apply button to accept and save the configuration.

13. If you have not already done so, install the operating system. See the server documentation or the documentation provided with the operating system for more information.

After you install the operating system, see “ServeRAID device drivers and utility programs (installation)” on page 130 (or the installation instructions provided with the server) for information about installing the ServeRAID device drivers and utility programs.

Menu bar:

Descriptions of the choices available from the Menu Bar are as follows:

File The File pull-down menu contains the

following choices in the Information mode:

 Save Configuration Event Log: Select

this choice to save configuration event information (such as the start time and completion time for a rebuild operation) to a file.

 Clear Configuration Event Log:

Select this choice to erase the event information stored in the Configuration Event Log.

 Exit: Select this choice to exit from the

ServeRAID Configuration Program.

View The View pull-down menu contains the

following choices in both the Information and Configuration modes:

 Small Icons: This is the default setting.

When you select this choice, small icons appear in the Main Tree on the left and the Main Panel on the right.

 Large Icons: Select this choice to

display large icons in the Main Tree on the left and the Main Panel on the right.

 Options: Select this choice to change

the Initialization and Synchronization mode, as follows:

86 Netfinity Server HMM

– Basic: This is the default setting.

When this mode is Enabled, the configuration program automatically initializes each new logical drive and prevents access to the manual initialization and synchronization functions. This choice also forces the synchronization of all new RAID level-5 logical drives attached to older ServeRAID adapter or controller models that do not support the auto-synchronization feature.

– Advanced: When Enabled, this

choice lets you select to automatically initialize new logical drives and force the synchronization of all new RAID level-5 logical drives before exiting the ServeRAID Configuration Program.

Attention

If you disable Automatic Initialization, the ServeRAID Configuration Program will not initialize each logical drive (by writing zeros to the first 1024 sectors of the logical drive) when it is created. You still must initialize all newly defined logical drives before storing data. If you disable the synchronization feature and the level of firmware being used by the ServeRAID adapter or controller does not support the auto-synchronization feature, you still must synchronize all RAID level-5 logical drives before storing data.

Actions All choices available from the Actions

pull-down menu also are available from the pop-up lists that appear when you use the right mouse button and select the object in the Main Tree.

The following choices appear on the Actions pull-down menu when you select a ServeRAID controller from the Main Tree:

 Configure the ServeRAID Controller:

This choice is available in the Information mode only. It appears on the pull-down menu when there are

Netfinity 5500 M20 - Type 8662

Ready drives and logical-drive slots still available for the ServeRAID controller.

 Configure for Clustering: This choice

is available in the Information mode only. You can select this choice to define the ServeRAID controller for use in a high-availability, shared-disk cluster environment. Detailed instructions for using the clustering features are provided in the

IBM Netfinity High-Availability Cluster Solution Installation and User's Guide

. You can obtain a copy of this manual at the following address on the World Wide Web:

http://www.ibm.com/pc/us/ netfinity/clustering

 Initialize the Controller Configuration:

This choice is available in both the Configuration and Information modes. Select this choice to delete the ServeRAID controller configuration.

Attention

After you initialize the controller configuration, you will not have access to any data stored on the logical drives attached to the selected ServeRAID adapter or controller.

This choice deletes the existing configuration information, sets all functional hard disk drives attached to the controller to the Ready state, and deletes all logical drives defined for the controller.

This choice

does not

change any of the ServeRAID adapter or controller settings (such as the stripe-unit size, rebuild rate, and so on) from their current or customized values.

 Copy the Configuration from the

Drives to the Controller: This choice

is available in the Information mode only; it copies the configuration information stored on the hard disk drives to the ServeRAID controller. This function is useful when you import previously configured drives from another system, or when you replace the ServeRAID adapter or controller.

 Disable or Enable Read-Ahead Cache

Mode: These choices are available in

the Information mode only. When read-ahead cache is set to Enabled (default setting), the ServeRAID controller transfers data from a disk to its local cache in increments equal to the stripe-unit size. This provides excellent overall performance when workloads are steady and sequential. However, if the workload is random or the system I/O requests are smaller than the stripe-unit size, reading ahead to the end of the stripe might degrade performance. When read-ahead cache is set to Disabled, the ServeRAID controller transfers data from a disk to local cache in increments equal to the system I/O request size, without reading ahead to the end of the stripe.

 Change the Rebuild Rate: This choice

is available in the Information mode only. You can select this choice to set the priority for Rebuild operations to High (default), Medium, or Low.

– When the rebuild rate is set to

High, the rebuild I/O request gets high priority in the execution order.

– When the rebuild request is set

from High to Medium in a heavily loaded system, it can increase the rebuild time, but provide better system performance.

– When the rebuild request is set

from High or Medium to Low in a moderate to heavily loaded system, it can increase the disk rebuild time, but provide better system performance.

 Change the Stripe-Unit Size: This

choice is available in the Information mode only.

Attention

After you configure an array and store data on the logical drives, you cannot change the stripe-unit size 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 a size

Netfinity 5500 M20 - Type 8662 89

that is close to the size of the system I/O request. You can set the stripe-unit size to 8 KB, 16 KB, 32 KB, or 64 KB. When the stripe-unit size is 8 KB (the default setting) or 16 KB, the maximum number of physical drives supported in an array is 16. When the stripe-unit size is 32 KB or 64 KB, the maximum number of physical drives supported in an array is eight. (See “Interleave depth and stripe-unit size” on page 67 for more information.)

 Scan for New or Removed Ready

Drives: This choice is available in the

Information mode only. When you select this choice, the configuration program scans all channels on the ServeRAID controller for new or removed Ready drives.

The following choices appear on the Actions pull-down menu when you select the Arrays icon or a specific array icon from the Main Tree:

 Create an Array: This choice appears

in the Information mode if you select the Arrays icon and Ready drives are available. When you select this choice, the configuration program switches from the Information mode to the Configuration mode.

 Delete All Arrays: This choice is

available in the Information mode only. It appears on the Actions pull-down menu if you select the Arrays icon from the Main Tree and arrays are defined for the controller.

 Delete Array: This choice is available

in the Information mode only. It appears on the Actions pull-down menu when you select a specific array icon from the Main Tree.

The following choices appear on the Actions pull-down menu when you select the Logical Drives icon or a specific logical drive icon from the Main Tree:

 Create a Logical Drive in Array: This

choice appears on the Actions pull-down menu in the Information mode if you select the Logical Drives icon and free space is available in one or more arrays.

 Change Write-Cache Mode to Write

Through or Write Back: These

choices are available in the Information

90 Netfinity Server HMM

mode when you select a specific logical drive icon from the Main Tree.

When this feature is set to the write-through mode, the completion status of a write command is sent

after

the data is written to the hard disk drive. Under certain workloads, you can improve performance by changing this setting to the write-back mode, where the completion status of a write command is sent to cache memory, but

after

the data is copied

before

the data is

actually written to the storage device.

Attention

1. You might lose data if a power outage occurs while using the write-back mode without a battery-backup cache device.

2. If you do not have a battery-backup cache installed and Enabled and you set this feature to the write-back mode, wait at least 10 seconds after the last operation before you turn off the system. Failure to follow this practice can result in lost data.

 Synchronize: This choice is available

in the Information mode when you select a logical drive from the Main Tree and the following conditions are both true:

– The ServeRAID adapter or

controller does not support the auto-synchronization feature.

– You previously selected Options

from the View pull-down menu and disabled the “Synchronize all new

RAID level-5 logical drives” setting. Synchronizing a logical drive verifies that the data redundancy for the logical drive is correct. You must synchronize all RAID level-5 logical drives before storing data. (See page 79 for more information.)

 Initialize: This choice is available in the

Information mode when you select a logical drive from the Main Tree and you previously selected Options from the View pull-down menu and disabled the “Automatically initialize new logical drives” setting.

Netfinity 5500 M20 - Type 8662

 Unblock the Logical Drive: This

choice appears in the Information mode when you select a specific logical drive that is in the Blocked state. You can select this choice to change the Drive Access setting for the RAID level-0 logical drive from Blocked to Unblocked. During a rebuild operation, the ServeRAID controller sets the state of any RAID level-0 logical drives associated with a failed array to the Blocked state.

The following choice appears on the Actions pull-down menu when you select a hot-spare drive from the Main Tree:

 Remove from Hot-Spare State: This

choice is available in the Information mode only. Select this choice to remove a hot-spare drive from the configuration and set the drive state back to Ready.

The following choices appear on the Actions pull-down menu when you select a physical drive, a physical drive icon, or a SCSI channel icon from the Main Tree:

 Set Drive State to Hot Spare: This

choice is available in the Information mode only. It appears when the physical drive that you select from the Main Tree is in the Ready state. You can select this choice to add the drive to the configuration and to change its state from Ready to Hot Spare.

 Set Drive State to Online: This choice

appears in the Information mode, and you can use it to change the state of a drive from Defunct to Online.

Attention

You might lose data by setting a Defunct physical drive that is part of an array to Online.
