Terminology
Some of the terms you need to understand as you read this guide are defined as
follows:
Disk array: A set of disk drives and a specialized array controller. The array
controller keeps track of how data is distributed across the drives.
Drive group: A set of drives logically tied together and addressed as a single unit.
ECU: EISA (System) Configuration Utility is used to configure EISA option boards.
JBOD: Sometimes referred to as "just a bunch of disks." Each drive operates
independently and is seen by the operating system as a single drive. There is no data
redundancy in this RAID configuration.
Logical RAID drive: A section of storage space presented to the host operating
system as a single physical drive.
RAID: An acronym for a redundant array of independent (sometimes referred to as
inexpensive) disks.
RAID level: A numerical designator (0 to 5) assigned to each scheme of data
management possible in an array of drives. RAID levels supported by the SWXCR
controller include the following: RAID 0, RAID 0 + 1, RAID 1, and RAID 5.
SBB: System building block. A modular carrier plus the individual mechanical and
electromechanical interface required to mount it into a standard shelf. Any device
conforming to shelf mechanical and electrical standards is considered an SBB.
Write-Back caching: A caching policy in which the controller acknowledges that a
write operation has completed successfully before data is written to the disks. If you
choose this caching policy, you may increase the I/O performance of your RAID
subsystem, but if there is a power failure, you lose data in cache that is not yet written
to the disks.

About this Guide

Write-Through caching: A caching policy in which the data is written to disk before
the controller acknowledges that a write operation is completed successfully. If you
choose this caching policy and there is a power failure, you minimize the chance of
data loss.

StorageWorks RAID Array 200 Subsystem Family

RAID Overview
RAID (redundant array of independent disks) is a modular, integrated, end-user
solution that provides three main benefits:
•

Improved data availability

•

Improved I/O performance

•

Increased scaleability

A RAID array is a set of multiple disk drives and a specialized array controller that
manages how data is distributed across disk drives.
Data for a given file is divided into segments, which can be written across multiple
drives. A segment is a group of blocks that is continuous data which can be stored on
a disk drive. By using more than one drive, the array can provide higher data transfer
rates when compared to a single large drive. Depending on the RAID level used,
arrays can also provide redundancy to protect data availability.
As you configure your subsystem, select the RAID level appropriate for your
computing environment.

Raid Levels
RAID 0, 1, 0 + 1, 5 and JBOD are supported by the StorageWorks RAID Array 200
Subsystem Family and offer data redundancy/performance.

Raid 0
RAID 0 stripes data across the drives in the array, one segment at a time. RAID 0
offers a high I/O rate, but is a nonredundant configuration. No array parity
information is generated for reconstructing data if a drive fails.

Raid 1
RAID 1 transparently mirrors data by writing data to two drives simultaneously. This
is the simplest way of to achieve data redundancy. The cost of data storage is greater
than for a single drive, since double the disk space is required. However, RAID 1 is a
consideration for users where reliability is most important.

1-4

Chapter 1

Raid 0 + 1
RAID 0 + 1 is achieved in a multidrive RAID set by the combination of striping
mirrored sets. RAID 0 + 1 provides data redundancy and is beneficial for any critical
high-availability application. If a drive fails in a RAID 0 + 1 array, you can continue
to use the array normally since data from its mirrored drive is automatically retrieved.

Raid 5
RAID 5 combines striping (writing data across the set of drives) and storing parity
across all drives. If a drive fails in a RAID 5 array, you can continue to use the array
normally since the array controller automatically regenerates the data from the failed
drive using data and parity blocks from other operational drives. All data remains
accessible even when one drive fails.

JBOD
JBOD is an acronym for "just a bunch of drives." This mode allows a disk drive to be
accessed independently similar to using a non-RAID SCSI disk controller. This mode
does not provide any data redundancy.

1-5

StorageWorks RAID Array 200 Subsystem Family

Logical RAID Drive States
The logical RAID drive or grouping of drives can be in different states. There are four
possible states as shown in Figure 1-1 and described in Table 1-1.

Figure 1-1. Logical RAID Drive State Diagram

Table 1-1. Logical RAID Drive States

1-6

States

Description

Optimal

The array is operating at an optimal level. This is the
condition during normal operation.

Degraded

The logical RAID drive is operating in degraded mode. The
array is still functioning, but a single drive could have
failed. This state is only valid for RAID levels that provide
redundancy (1, 0 + 1, 3, and 5). To return the logical RAID
drive unit to optimal, rebuild (reconstruction) of the data
must be done.

Dead

The logical RAID drive unit is no longer functioning. This
is typical when two or more drives have failed.

Rebuild (Reconstruction)

The controller is currently rebuilding the logical RAID drive
unit using good data and parity information. This state is
valid only for RAID levels, 1, 0 + 1, 3, and 5 which provide
redundancy.

Chapter 1

Drive Number and RAID Level
The choice of RAID level for logical RAID drives depends on the number of drives
within a drive group. The following table lists the RAID levels for drive group and
RAID level requirements.

Using the EISA Configuration Utility
Introduction
This chapter describes the major steps for running the EISA Configuration Utility
(ECU). Your system documentation may call this utility the System Configuration
Utility (SCU).
You use the ECU to configure your system's EISA nonvolatile memory whenever you
add or remove EISA controllers. When you boot your system, the system BIOS uses
the contents of the EISA nonvolatile memory to initialize your system's EISA
controllers.

Order of Installation
We recommended you install your subsystem in this order:
1.

Run the ECU.

Install the RAID controller.

Connect the cables and storage pedestal(s).

Label and install the disk drives.

To install a second controller (1-channel or 3-channel), repeat the above installation
procedures. If you have two controllers, Controller 1 is the controller that is in the
EISA slot with the lowest EISA slot number and Controller 2 is the other controller.

2-1

StorageWorks RAID Array 200 Subsystem Family

Background
Use the Standalone RAID Array 200 Software to configure and maintain your
StorageWorks RAID Array 200 Subsystem.
Before you can use your RAID subsystem, you must configure the disks into drive
groups, and then configure logical RAID drives (see the terminology section of this
guide) at a particular RAID level using the Standalone RAID Array 200 Software.
Once you complete the configuration process, the configuration data is saved in the
RAID controller's flash EEPROM/NVRAM (the controller's memory). However, you
should also save the configuration data to a file on a diskette so that you can restore it
in case the controller is ever replaced.

5-1

StorageWorks RAID Array 200 Subsystem Family

System Requirements
You must have the following to run the utility:
•

An Intel or Alpha AXP system with a VGA monitor and a keyboard

•

One floppy disk drive (3.5-inch, 1.44 MB)

•

SWXCR controller installed and all disk drives connected and powered on.

Before You Begin
Make a backup copy of the Standalone RAID Array 200 Software diskettes (the Intel
x86 or AXP diskette, whichever you are using on your system) on a PC using this
procedure.

5-2

Copy the diskette using the MS-DOS diskcopy command (see your MS-DOS
manual for detailed instructions on how to use this command).

Label the new diskette and store the original diskette in a safe place.

utilities. During the procedure, you use the utilities to perform the
following steps:

5-8

•

Configure one or more drive groups

•

Configure one or more logical RAID drives
−

Specify RAID levels

−

Specify caching policy

•

Initialize drives with RAID parity information

•

Specify a hot spare drive if you choose to include one

Chapter 5

Initial Configuration of the RAID Controller
At the initial installation, set the Fault Management and Battery Backup options. You
only need to set these options once.
For the Fault Management option, consider the following:
•

as shown in Figure 5-5.

As each drive group is arranged, its
information is added to the table.

When you have set up all your
drive groups, go on to the next step
to create logical RAID drives.

To continue the configuration of a new disk array, specify the logical RAID drives.

5-22

Chapter 5

Creating a Logical RAID Drive
A logical RAID drive is presented to the host operating system as one physical drive.
To the operating system, there is no difference between a controller logical RAID
drive and a single physical drive on a conventional disk controller. A logical RAID
drive consists of part or all of any drive group.
______________________ NOTE ____________________________
For a RAID 5 configuration, the controller must use some of the space for
parity information. When you specify the size, calculate the usable space
according to this formula:
usable space = total space * (N-1/N) where N is the number of drives in
the drive group.

Step
1

Action
Select the Define Logical Drive option.

Result
A screen shows the drive groups
available for selection as logical RAID
drives.

Select the Create Logical Drive option.

A pop-up window displays the RAID
levels available for that logical RAID
drive. Unavailable levels are still
visible but you cannot select them.

Select the RAID level for the logical
RAID drive.

A pop-up window displays the usable
size of the logical RAID drive.

Enter a size for the new logical RAID
drive.

The status block is updated with the
RAID level and size of the logical
RAID drive.

Confirm that you want to create this
logical RAID drive. Select Yes.

The system adds the logical RAID
drive to the list at the lower-left of the
screen.

Continued on the next page.

5-23

StorageWorks RAID Array 200 Subsystem Family

Step
6

policy is Write-Thru (Through).

The cursor moves to the right-hand
column of the list of logical RAID
drives and highlights the Write-Thru
of the first logical RAID drive.

To change the cache policy, select the
Toggle Write Policy option on the menu.
NOTE: Digital strongly recommends a
Write-Through caching policy to eliminate
the chance of data loss due to a power
failure. See the Terminology section in the
About this Guide portion of this manual.

Chapter 5

Initializing a Logical RAID Drive
Before you can use a logical RAID drive, it must be initialized to ensure consistent
RAID parity information. For RAID levels that provide redundancy, this step is
crucial to ensure that the RAID parity information is consistent from the beginning.
_____________________ CAUTION ___________________________
Do not initialize a logical RAID drive if it has valid data. Initialization
overwrites and destroys all data.

After you initialize a logical RAID drive, do not change or rearrange the physical
drives or cables. Otherwise, all data in the drive group can be lost.

Chapter 5

Manual Rebuild of a Drive (Reconstruction)
A rebuild is a process of recreating data on a new drive in a configuration with a
redundant RAID level (for example, RAID 1, RAID 0 + 1, and RAID 5). If your
logical RAID drive was configured with a RAID level that does not support data
redundancy, all data is lost if a drive fails.
There are three ways to rebuild a drive.
With a Hot Spare
If you defined a spare drive, when a SCSI drive fails, the RAID controller
automatically starts to rebuild the information on a hot spare. A hot spare is set to
write only so data is not corrupted during the rebuild.
With a Hot Swap
If you replace a drive while the RAID subsystem is operating and you enabled the
Fault Management option (as described earlier in this chapter) the RAID controller
automatically starts the rebuild. This operation is called a hot swap.
______________________ NOTE ____________________________
It may take up to one minute for the automatic rebuild to begin.

For a Manual Rebuild
You can rebuild a SCSI drive that you failed manually or a drive that could not be
rebuilt because either an automatic rebuild is in progress or the Fault Management
option was not enabled.

5-45

StorageWorks RAID Array 200 Subsystem Family

______________________ NOTE____________________________
To minimize the chance of data loss due to a second drive failure, upon
detection of a drive failure, replace the drive as soon as possible.

To manually rebuild data of a failed physical drive (if you have not defined a hot
spare drive), follow these steps.

Step
1

Action
Remove the failed drive from the RAID
subsystem and replace it with a new drive.

Result

Go to the main menu and select the Rebuild
option.

The system displays a screen
with the drive matrix, showing
the drives and their status.
The new drive is recognized by
the system and spun up. The
status of the new drive remains
FLD (failed) until the rebuild
begins.

5-46

Select the drive to be rebuilt. The drive you
select must have a FLD (failed) status.

The rebuild status bar gradually
fills as the process completes.

When the bar displays 100%, press any key to
continue.

The system returns you to the
main menu.

Chapter 5

Viewing the Bad Blocks on a Drive
During a rebuild, the bad block table receives entries from a rebuild with errors. If
you are using the Rebuild option to rebuild a disk and the rebuild fails, the drive
remains in the WOL (write only) state. You can use the Bad Block Table option to
view the bad blocks.
Step
1

Action
Select the Tools option from the
main menu.

Result
The system displays the Tools menu as
shown in Figure 5-7.

Select the Bad Block Table option
from the Tools menu.

The system displays the View Bad Block
Table menu at the lower-left side of the
screen. You can select one of these
options:

•

View Rebuild BBT

•

View Write Back BBT

Select the View Rebuild BBT.

The system displays bad blocks on the
logical RAID drive including the block
number and the number of consecutive bad
blocks encountered.

Press any key to return to the View
Bad Block Table menu.

Table once it is read. You can save it to a
file.

Press the ESC key to return to the
main menu.

The system displays the main menu.

If you have Write-Back cache enabled, the bad block table receives information on
any errors encountered during a write. You can use the View Write Back BBT option
on the View Bad Block Table menu to view this information. This option works like
the View Rebuild BBT described above.

5-47

StorageWorks RAID Array 200 Subsystem Family

Making a Drive Optimal
In some circumstances described in the Troubleshooting Your Subsystem section of
Chapter 6, you may have to use the Make Optimal option to change the state of a
drive from failed (FLD) to (OPT) optimal. If you use this method to change the state
of a drive instead of using the Rebuild option, the drive may contain faulty data.
_____________________CAUTION __________________________
When you use this option, ensure the integrity of the data stored on all
logical RAID drive(s) that use the failed drive. For example, do the
following:
• For drives with a redundant RAID level (RAID 1, 0 + 1, or 5), use the
Parity Check option from the Tools menu.
• Run an operating system file integrity check.
• Run a data integrity check of your files (application-specific).
If corrupted files are detected, you have to restore data from backups.

To change the status of a drive to optimal, use these steps.

5-48

Step
1

Action
Select the Tools option from the
main menu.

Result
The system displays the Tools menu as

Troubleshooting Your Subsystem
This section contains troubleshooting information to correct problems that may be easy to fix. It
also directs you to the appropriate documentation for further troubleshooting if needed.

Before You Begin Troubleshooting
_______________________ NOTE_____________________________
Always turn off the power to your system before you turn off the power to
your storage pedestal(s).

To determine what the problem with your SWXCR controller is when using packaging other than
the StorageWorks pedestal or shelves, follow these steps:
1.

Turn off your host system.

Turn off the power to your pedestal, shelves, and drives.

Check to see that the SCSI cables are connected correctly to the storage pedestal,
shelves, and drives. Check for proper SCSI cable termination.

If you are using the StorageWorks storage pedestal or shelves with your SWXCR controller,
follow these steps:
1.

Turn off your host system.

Turn off power to your StorageWorks pedestal or shelves.

Check to see that the SCSI cables are connected correctly. Refer to Chapters 3
and 4, for proper cabling instructions.

Turn the StorageWorks pedestal or shelves back on.

6-9

StorageWorks RAID Array 200 Subsystem Family

Verify that all the drives LEDs flash on when you turn the power on.

Verify that the two LED indicators on the power supplies are on.

Turn on your system and see if the problem is now resolved.

Troubleshooting Techniques
When the controller or subsystem does not operate correctly, use the information in this section to
diagnose the problem. The troubleshooting techniques described do not identify all possible
problems with the SWXCR controller or StorageWorks pedestal or shelves, nor do the corrective
actions suggested correct all problems.
To use Table 6-4, follow these steps:
1.

Note the symptoms of the problem displayed by the controller, storage pedestal,
or shelves.

See if the description of the problem in the Symptom column in Table 6-4 is
similar to yours.

Check the conditions for that symptom in the Possible Cause(s) column. If more
than one possible cause is given, check all of the possible causes in the order
listed.

Follow the directions in the Action(s) to Take column.
