Chapter 1. Introducing the SSA RAID Adapter

1.0 Chapter 1. Introducing the SSA RAID Adapter

The IBM SSA RAID Adapter for PC Servers is a PCI bus-master adapter that serves as the interface between systems using the

Peripheral Component Interconnect (PCI) architecture and devices using the Serial Storage Architecture (SSA). The SSA RAID

Adapter provides RAID functions.

SSA

1.1 SSA

SSA is a high-performance serial-interconnect technology used to connect I/O devices and host adapters. SSA is an open

standard, and SSA specifications have been approved by the SSA Industry Association and are in the process of being approved as

an ANSI standard through the ANSI X3T10.1 subcommittee. SSA retains the SCSI-2 commands, queuing model, status, and sense

bytes.

In SSA subsystems, transmissions to several destinations are multiplexed; the effective bandwidth is further increased by spatial

reuse of the individual links. Commands are forwarded automatically from device to device along a loop until the target device is

reached. Multiple commands can be travelling around the loop simultaneously.

The Adapter Card

1.2 The Adapter Card

The adapter provides 4 SSA ports for the attachment of storage devices such as hard disk drives. Each port operates at 20 MB/s

full-duplex using point-to-point copper cables up to 25 meters long.

On the adapter card, there is a light next to the pair of SSA connectors (port 1 and port 2) for each SSA loop.

The light is on continuously when power is turned on to the adapter and both ports for that loop are operational; that is, the

devices connected next to the adapter in the loop have power turned on to them, are connected correctly to the adapter, and are

operational.

The light flashes continuously if one of the ports is not operational. That occurs when the cable to that port is not connected

correctly or the device connected next to the adapter in the loop is not operational.

The light is off if both ports are not operational

On the front panel of the adapter and on one of its modules are labels on which is printed the 15-character SSA unique ID of the

adapter.

RAID

1.3 RAID

array

RAID (redundant array of independent disks) is the technology of grouping several hard disk drives into an

that is defined as a

single logical disk drive. This grouping technique greatly increases logical-disk capacity and data availability. In addition, if one disk

fails, the system continues to run (except in the case of RAID-0), with no operator intervention required, at reduced performance.

hot swapping

The failed disk can be replaced without turning off the server (

The SSA RAID Adapter provides RAID functions within the interface between your server and its disk drives. Disk drives connected

to the adapter can be configured as individual drives, as members of a RAID-0, RAID-1, or RAID-5 array, or as hot spares for future

use in an array. The members of an array can be disk drives only; that is, an array cannot be a member of another array.

If you need some basic information about RAID technology, refer to Appendix C, "Introducing SSA and RAID" in topic C.0.

Installing the Adapter Card

2.1 Installing the Adapter Card

Attention: Remove all power from your PC server and any attached devices before removing the cover.

User's Handbook

To install the adapter card, refer to the documentation that came with your PC server. The

for your server

describes how to install an adapter. Perform the steps described in that book, ensuring that you perform the actions relating to the

static-protective package correctly. When choosing a slot for the SSA RAID Adapter, take note of the following restrictions and

recommendations:

The SSA RAID Adapter card is a long PCI adapter card. On some models of PC Server, there is only one slot in which a long

PCI adapter card can be installed without interference with the heat sink on the processor. In these models, if might be

necessary to move previously installed adapter cards before installing the SSA RAID Adapter card.

If you are installing one or two SSA RAID Adapter cards in a PC Server 720, to obtain the best performance, use the primary PCI

bus (slots 6 and 7). If, because one or both of these slots is already occupied, you cannot use the primary bus for all the SSA

RAID Adapter cards that you are installing, use the secondary PCI bus (slots 1 through 5) for all the SSA RAID Adapter cards.

If you want to boot from an SSA disk drive and the system has a SCSI PCI adapter, you must install the SSA adapter in a PCI

slot with a higher priority than the slot used by the SCSI adapter. In some servers, slots with lower numbers have higher priority,

User's Handbook

in other servers, higher numbers mean higher priority; the

for your server describes which rule applies.

Connecting the Disk Drives

2.2 Connecting the Disk Drives

Each of the 2 pairs of SSA ports can attach up to 48 dual-port devices in a closed loop. Only one SSA adapter can be included in a

loop.

"SSA Loops and Links" in topic C.1.1 provides a general description of SSA loops and some rules for cabling valid configurations.

To connect the cables:

1. Connect the cables from the devices to the appropriate pair of connectors on the adapter card.

2. Turn the retaining screws on the SSA cable connectors fully clockwise to ensure that a good ground connection is made.

Configuring the Disk Drives

2.3 Configuring the Disk Drives

Turn power on to the server unit and to the devices. Your system automatically performs the PCI configuration tasks, which

recognize the new adapter and devices during the boot process.

SSA RAID Adapter Installation and User's Guide.

Installing an Operating System

2.4 Installing an Operating System

If an operating system is already loaded in your server, go to the next section, "Installing the Device Drivers and Utility Programs" in

topic 2.5.

If you are installing an operating system on your new SSA RAID subsystem:

1. Boot DOS by:

a. Inserting the PC-DOS Configurator and Utilities diskette provided with the adapter

b. Turning power off and on again to the server.

When the 'CBIOS is currently disabled' message is displayed, press the tab key; this enables the CBIOS.

2. Run the configuration utility which is provided on the PC-DOS Configurator and Utilities diskette. (The details of this procedure

are given in Chapter 3, "Configuring SSA Subsystems" in topic 3.0.) This defines the way that the adapter uses the disk drives

that are attached to it.

Notes:

a. Systems cannot access SSA disk drives until you have used the configuration utility to attach the disk drives and arrays.

b. Installing an operating system on a single disk drive or RAID-1 array can give better performance.

3. Install the new operating system using the installation instructions provided with the operating system.

Note: Some operating systems have restrictions on partition size.

4. Install the device drivers and utility programs; how to do this is described in "Installing the Device Drivers and Utility Programs" in

topic 2.5.

5. The SSA subsystem is now ready for use with your system.

SSA RAID Adapter Installation and User's Guide.

Installing the Device Drivers and Utility Programs

2.5 Installing the Device Drivers and Utility Programs

A README.TXT file on the SSA RAID Adapter diskette for your operating system provides detailed instructions on installing the

device drivers.

Unless you have just installed an operating system, you must configure your disk arrays before you can use them with your system.

Chapter 3, "Configuring SSA Subsystems" in topic 3.0 describes how to do this.

When you have configured your disk arrays, the SSA subsystem will be ready for use with your system.

The format in which the Event/Error Logger reports errors is controlled by the file EVNCTRLF.TXT in the install directory (which, by

default, is c:\issa). Details of the settings and how to change them are contained in the header of the control file.

Selecting Your Boot Device

2.6 Selecting Your Boot Device

To boot from an SSA disk drive: during the boot process, if the message CBIOS disabled appears, press the tab key. After this

action, whenever you boot your server, it will boot from the primary SSA disk drive and the message CBIOS enabled will appear.

To return to booting from the previous default device: if the message CBIOS enabled appears, press the tab key.

If you have problems booting from an SSA disk drive, refer to "Basic Problems" in topic 4.1.

Chapter 3. Configuring SSA Subsystems

3.0 Chapter 3. Configuring SSA Subsystems

Before new SSA disk drives can be used by the operating system, you must configure them into the SSA subsystem. You use the

configuration utility (which is provided on each of the diskettes supplied with the adapter) to do this. The actions that you must

perform are:

1. Accept the new disk drives into the subsystem

2. Configure disk arrays, if required

3. Attach the disk arrays or individual disk drives to your system.

The following sections describe the details of these actions.

Attaching Resources

3.4 Attaching Resources

A resource is a disk drive that is to be accessed individually or an array of disk drives.

Before attaching an array, ensure that it has finished the rebuilding process and that no problems occurred during this process.

Any problems are shown in the attributes of the array; "Viewing Resources and Their Attributes" in topic 5.3 describes how to see

this information.

To attach a resource to your system:

1. From the SSA Main Menu screen, select System Resources.

A list, initially blank, of the resources attached to the system is displayed; the resources are listed in drive-address order. (Drive

attached

addresses are allocated by the configurator.) Only resources that are

can be accessed by the operating system.

immediately above this one) and press Insert.

To add a resource to the end of the list, highlight the space below the current end of the list and press Insert.

Notes:

1) If you are going to boot from an SSA disk drive, that disk drive must be at the top of the list. For details of the requirements

for booting from an SSA disk drive, refer to the README.TXT file on the Device Driver and Utilities diskette for your operating

system.

2) At the position in the list that you choose for the new resource, there must be a large enough gap in the sequence of drive

addresses. If the gap is not large enough:

For OS/2, the system creates a large enough gap by adjusting downward the drive addresses of resources below the

gap.

For Novell NetWare, the system rejects your choice of that position.

For Windows NT, the system gives a warning that you might destroy data by selecting that position.

Basic Problems

4.1 Basic Problems

If the system cannot work with the adapter, check the following:

Is CMOS setup required to enable PCI bus parameters

Is the adapter installed in a bus-master PCI slot

Are all the cables connected correctly

Does the configuration follow the SSA rules for this adapter

If the system cannot access the SSA disk drives, check the following:

Is power turned on to the disk drives

Has the configuration utility been run for all the required disk drives, and do they appear in the list of attached resources

Are the disk drives connected in a loop, either from SSA loop A port 1 to SSA loop A port 2, or from SSA loop B port 1 to SSA

loop B port 2?

Is the light next to the adapter-loop ports on, showing that both ports are operational

If the system fails to boot from an SSA disk drive, check the following:

That there isnot an IDE disk drive installed

That there isnot a SCSI adapter with BIOS enabled installed in a higher-priority PCI slot than the SSA adapter

That the CBIOS enable

That the SSA device drivers are loaded before the SCSI device driver

That the address (drive letter) of the partition from which you are trying to boot has not changed. (Adding extra drives can cause

the addresses of existing drives to be changed.)

Array Problems

4.2 Array Problems

Many problems within an array are not seen by the users of the server. The RAID-1 and RAID-5 functions provide a continuing

service to the users even when a member of an array has failed. However, unless the failure is corrected, a second failure within

that array could cause the whole array to become unavailable. Therefore, it is very important that you check the error log for the

adapter regularly. You could do this by making such a check part of the startup procedure for your operating system.

If you are using OS/2, a pop-up window appears when an error is logged for the adapter or the disk drives attached to it. Also, the

pop-up window appears every hour while an error likely to affect the operation of the array remains on the log. The pop-up window

recommends that you check the entries in the error log.

To check the error log:

1. Start the configuration utility by executing the following program:

For OS/2: ISSACFG

For Novell NetWare: load ISSACFG

For Windows NT: ISSACFG

For DOS: ISSACFG

or, if it is available, double click on the SSA Configurator icon.

2. From the Main Menu, select Event/Error Logger and then Analyze SSA Event Log.

The current list of errors appears in a new window:

In this example, four disk drives are connected between ports A1 and A2 of the adapter, in a loop, in the order shown. There are

no disks connected to ports B1 and B2.

If a dotted line appears in the list of disk drives, it indicates that the SSA loop is broken at that place.

2. You can identify a disk drive by highlighting its entry in this list and pressing F9. This causes the Check light on the disk drive to

flash (if it is not on already) and a > symbol appears beside the entry in the list. Pressing F10 stops the light flashing.

3. Highlight the entry for the disk drive that you are going to replace and press F4.

This puts that disk drive into service mode; the Check light on the disk drive comes on (it might be on already) and a + symbol

appears beside the entry in the list. Only one disk can be in service mode at a time.

5. Highlight the entry for the disk drive that you are have just replaced and press F4.

This removes that disk drive from service mode.

6. Press Esc to return to the Main Menu. (Leaving the Service Aids window automatically removes any disk drive from service

mode.)

7. If the disk drive that failed was a member of an array for which no hot spare was available, the entry for the failed disk drive in the

list of members of the array is replaced with

You must add the new disk drive to the array by exchanging this entry

with that for the new disk drive, using the procedure described in

"Exchanging a Member of an Array" in topic 5.5.

If the disk drive that failed was a member of an array for which a hot spare was available, the hot spare will have been exchanged

automatically with the faulty disk drive. You can either:

SSA Loop Configurations that Are Not Valid

B.1 SSA Loop Configurations that Are Not Valid

Note: This section is related to SRN 48000.

SRN 48000 shows that the SSA loop contains more devices or adapters than are allowed.

Each of the 2 pairs of SSA ports on a SSA RAID Adapter can attach up to 48 devices in a closed loop.

Only one SSA RAID Adapter adapter can be included in a loop.

If the SRN occurred when you turned on the server:

1. Turn off the server.

2. Review the configuration that you are trying to make, and determine why that configuration is not valid.

3. Correct your configuration by reconfiguring the SSA cables or by removing the excess devices or adapters from the loop.

4. Turn on the server.

If the SRN occurred because additional devices or adapters were added to a working SSA loop:

1. Remove the additional devices or adapters that are causing the problem, and put the loop back into its original working

configuration.

It is important that you do these actions

Note:

, because they enable the configuration code to reset itself from the effects of the

error.

2. Review the configuration that you are trying to make, and determine why that configuration is not valid.

3. Correct your configuration by reconfiguring the SSA cables or by removing the excess devices or adapters from the loop.

Serial Storage Architecture (SSA)

C.1 Serial Storage Architecture (SSA)

Serial Storage Architecture (SSA) is an industry-standard interface that provides high-performance fault-tolerant attachment of I/O

storage devices. SSA is an open standard, and SSA specifications have been approved by the SSA Industry Association and are in

the process of being approved as an ANSI standard through the ANSI X3T10.1 subcommittee.

In SSA subsystems, transmissions to several destinations are multiplexed; the effective bandwidth is further increased by spatial

reuse of the individual links. Commands are forwarded automatically from device to device along a loop until the target device is

reached. Multiple commands can be travelling around the loop simultaneously. SSA retains the SCSI-2 commands, queuing model,

and status and sense bytes.

Subtopics

C.1.2 Rules for SSA Loops

C.1 - 1

SSA RAID Adapter Installation and User's Guide.

SSA Loops and Links

C.1.1 SSA Loops and Links

In the simplest SSA configuration, SSA devices are connected through two or more SSA links to an SSA adapter that is located in

the system unit. The devices, SSA links, and SSA adapter are configured in loops. Each loop provides a data path that starts at one

connector of the SSA adapter and passes through a link (SSA cable) to the devices. The loop continues through the devices, then

returns through another link to a second connector on the SSA adapter.

The maximum permitted length for an external cable that connects two SSA nodes (for example, disk drives) is 25 meters (82 feet).

Details of the rules for configuring SSA loops are given for each SSA adapter in "Rules for SSA Loops" in topic C.1.2.

Subtopics

SSA RAID Adapter Installation and User's Guide.

Loops and Data Paths

C.1.1.1 Loops and Data Paths

All devices that are attached to an SSA adapter card 1 are connected through SSA links 2 . The SSA links are configured in

loops. Data and commands to a particular device pass through all other devices on the link between the adapter and the target

device.

Data can travel in either direction round a loop. The adapter can, therefore, get access to the devices 3 (disk drives in this

example) through two data paths. The system cannot detect which data path is being used.

If a disk drive fails, or is turned off, the loop is broken, and one of the data paths to a particular disk drive is no longer available. The

disk drives on the remains of the loop continue to work, but an error is reported to the system.

In the diagram, disk drive number 3 has failed. Disk drives 1 and 2 can communicate with the system only through connector A1 of

the SSA adapter. Disk drives 4 through 8 can communicate only through connector A2 of the SSA adapter.

C.1.1.1 - 1

SSA RAID Adapter Installation and User's Guide.

Loops and Data Paths

If two or more disk drives are turned off, fail, or are removed from the loop, some disk drives might become isolated from the SSA

adapter.

In the diagram, disk drives 3 and 7 have been removed. Disk drives 1 and 2 can communicate with the system only through

connector A1 of the SSA adapter. Disk drive number 8 can communicate with the system only through connector A2 of the SSA

adapter. Disk drives 4, 5, and 6 are isolated from the SSA adapter.

connectors B1 and B2).

A maximum of 48 devices can be connected in a particular SSA loop

RAID technology stores data across groups of disk drives that are known as

using, this method of data storage provides the data redundancy that is needed for a secure system, and can allow faster retrieval

of data through multiple channel access. Also, if a disk drive fails, you can normally exchange that disk drive without interruption of

normal system operation.

The disk arrays can provide data redundancy that ensures that no data is lost if one disk drive in the array fails. The method that is

used to write data to an array is related to the level of RAID that you are using. Disk arrays are contained in array subsystems. You

can configure your subsystem with one or more arrays.

The SSA RAID Adapter provides RAID-0, RAID-1, and RAID-5 facilities and access to individual SSA disk drives that are not

configured as members of an array.

RAID-0

C.2.1 RAID-0

RAID-0 is also known as striping, it does not provide redundancy and, therefore, cannot survive the failure of a member. It does

provide a single large data space with the operations spread evenly across members. Short operations usually involve only one

member, longer transfers use several simultaneously and can, therefore, give higher data rates.

C.2.1 - 1

SSA RAID Adapter Installation and User's Guide.

RAID-1

C.2.2 RAID-1

RAID-1 is also known as mirroring or dual copy. It provides redundancy with better performance than a single disk, but requires real

disk capacity of two times the data size.

A RAID-1 array has two disk drive members. If the members have different capacities, the resulting RAID-1 array has the capacity

of the smaller member. Each data block of the array is written on each of the two members.

If one member fails, operations continue, to the good member. Performance is degraded for read operations (because read

operations cannot now be shared between the two members), and improved for write operations (because only a single member is

written). So a mixed workload may not show any change in overall performance. When a member returns or it is replaced (either

manually or automatically by the hot-spare mechanism), a rebuild occurs. This rebuild is performed in parallel with any activity to the

array.

C.2.2 - 1

SSA RAID Adapter Installation and User's Guide.

RAID-5

C.2.3 RAID-5

RAID-5 arrays write strips of data across all but one member of the array. Parity for the other strips is written on the last member.

The members of the array are used in rotation for the parity data.

RAID-5 arrays offer data protection , good throughput, and require fewer disks than RAID-1.

C.2.3 - 1

SSA RAID Adapter Installation and User's Guide.

Hot Spares

C.2.4 Hot Spares

A hot-spare disk drive is a disk drive that is defined for automatic use if a disk drive within an array fails. The hot-spare must have a

storage capacity greater than or equal to that of the smallest member of an array. You can define as many hot spares as you want.

Any RAID-1 and RAID-5 array on an adapter can use the hot-spare disk drives on that adapter.

If a disk drive within an array fails, at the next write operation to the array, the adapter automatically uses a hot spare instead of the

failed disk drive, and rebuilds the data that was on the failed disk on to the hot spare.

Disk Array States

C.2.5 Disk Array States

A disk array can be in one of several states. Those states are described here.

Subtopics

C.2.5.1 Good State

C.2.5.2 Exposed State

C.2.5.3 Degraded State

C.2.5.4 Rebuilding State

C.2.5.5 Offline State

C.2.5 - 1

SSA RAID Adapter Installation and User's Guide.

Good State

C.2.5.1 Good State

A disk array is in the Good state when all the member disk drives of that disk array are present and functioning correctly.

C.2.5.1 - 1

SSA RAID Adapter Installation and User's Guide.

Exposed State

C.2.5.2 Exposed State

A disk array enters the Exposed state when a member disk drive becomes missing (logically or physically) from that array. When a

disk array is in the Exposed state, you can reintroduce the missing disk drive, or exchange it for a new one. If necessary, the array

management software rebuilds the data that was on the original disk drive before it became missing, then writes that rebuilt data to

the replacement disk drive. When the data is correct, the array management software returns the disk array to the Good state.

Read Operations while in the Exposed State: When a read operation is performed on a disk array that is in the Exposed state, the

array management software recreates (rebuilds) the data that was contained on the missing disk drive.

Write Operations while in the Exposed State: When a write command is sent to a disk array that is in the Exposed state, the state of

the array is changed to Degraded.

C.2.5.2 - 1

SSA RAID Adapter Installation and User's Guide.

Degraded State

C.2.5.3 Degraded State

A disk array enters the Degraded state if, while in the Exposed state, it receives a write command.

If a hot spare disk drive is enabled and available, when the first write command is sent, the array management software immediately

exchanges the missing disk for the hot spare, rebuilds the data on it, and returns the disk to the Good state.

If no hot spare disk drive is available, and a write operation is performed on the array, the disk array remains in the Degraded state

until you take action to return that disk array to the Good state. While in this state, there is an exposure to data loss if a write

operation cannot be completed because of a loss of electrical power, for example. Therefore, it is recommended that you always

have a hot spare available.

If no hot spare disk drive is available, you exchange the failed disk drive for a new one. The array management software starts a

rebuild operation to write the original data to the new disk drive from the data that is contained in the other disk drives of the array.

This action returns the disk array to the Good state.

Attention: In this mode of operation, one data check can cause the loss of a large amount of data (more than 64 KB). The array

management software must do a complete rebuild of the disk array to recover the data.

C.2.5.3 - 1

SSA RAID Adapter Installation and User's Guide.

Rebuilding State

C.2.5.4 Rebuilding State

A disk array enters Rebuilding state after a missing disk has been replaced. When the disk array is in this state, all the member disk

drives are present, but the data and parity are being rebuilt on the replaced disk drive. The array management software allows read

and write operations on a disk drive that is in Rebuilding state. If the power fails before the rebuilding is complete, the array

management software continues the rebuilding operation when the power returns for those strips not yet rebuilt.

C.2.5.4 - 1

SSA RAID Adapter Installation and User's Guide.

Offline State

C.2.5.5 Offline State

A disk array enters Offline state when two or more disk drives become missing. Read and write operations are not allowed.

Production Status

D.1.1 Production Status

Each Machine is manufactured from new parts, or new and serviceable used parts (which perform like new parts). In some cases,

the Machine may not be new and may have been previously installed. Regardless of the Machine's production status, IBM's

warranty terms apply.

D.1.1 - 1

SSA RAID Adapter Installation and User's Guide.

The IBM Warranty

D.1.2 The IBM Warranty

IBM warrants that each Machine 1) is free from defects in materials and workmanship and 2) conforms to IBM's Official Published

Specifications. IBM calculates the expiration of the warranty period from the Machine's Date of Installation. The date on your receipt

is the Date of Installation, unless IBM or your reseller informs you otherwise.

During the warranty period, IBM or your reseller will provide warranty service under the type of service designated for the Machine

and will manage and install engineering changes that apply to the Machine. IBM or your reseller will specify the type of service.

For a feature, conversion, or upgrade, IBM or your reseller may require that the Machine on which it is installed be 1) the designated,

serial-numbered Machine and 2) at an engineering-change level compatible with the feature, conversion, or upgrade. Some of

these transactions (called "Net-Priced" transactions) may include additional parts and associated replacement parts that are

provided on an exchange basis. All removed parts become the property of IBM and must be returned to IBM.

Replacement parts assume the remaining warranty of the parts they replace.

If a Machine does not function as warranted during the warranty period, IBM or your reseller will repair or replace it (with a Machine

that is at least functionally equivalent) without charge. If IBM or your reseller is unable to do so, you may return it to your place of

purchase and your money will be refunded.

If you transfer a Machine to another user, warranty service is available to that user for the remainder of the warranty period. You

should give your proof of purchase and this Statement to that user.

D.1.2 - 1

SSA RAID Adapter Installation and User's Guide.

Warranty Service

D.1.3 Warranty Service

To obtain warranty service for the Machine, you should contact your reseller or call IBM. In the United States, call IBM at

1-800-772-2227. In Canada, call IBM at 1-800-565-3344. You may be required to present proof of purchase.

Depending on the Machine, the service may be 1) a "Repair" service at your location (called "On-site") or at one of IBM's or a

reseller's service locations (called "Carry-in") or 2) an "Exchange" service, either On-site or Carry-in.

When a type of service involves the exchange of a Machine or part, the item IBM or your reseller replaces becomes its property and

the replacement becomes yours. The replacement may not be new, but will be in good working order and at least functionally

equivalent to the item replaced.

It is your responsibility to:

1. obtain authorization from the owner (for example, your lessor) to have IBM or your reseller service a Machine that you do not own;

2. where applicable, before service is provided --

a. follow the problem determination, problem analysis, and service request procedures that IBM or your reseller provide,

b. secure all programs, data, and funds contained in a Machine,

c. inform IBM or your reseller of changes in a Machine's location, and

d. for a Machine with exchange service, remove all features, parts, options, alterations, and attachments not under warranty

service. Also, the Machine must be free of any legal obligations or restrictions that prevent its exchange; and

3. be responsible for loss of, or damage to, a Machine in transit when you are responsible for the transportation charges.
