Chapter 1. Getting started
Introducing IBM Director
This topic provides an overview of IBM Director.
IBM Director is an integrated suite of tools that provide you with comprehensive
system-management capabilities to maximize system availability and lower IT
costs. Its open, industry-standard design supports the management of a variety of
hardware and operating systems, including most Intel
systems and certain IBM System i, System p, System x, and System z servers.
IBM Director automates many of the processes that are required to manage
systems proactively, including capacity planning, asset tracking, preventive
maintenance, diagnostic monitoring, troubleshooting, and more. It has a graphical
user interface that provides easy access to both local and remote systems.
IBM Director can be used in environments with multiple operating systems and
integrated with robust workgroup and enterprise management software from IBM

IBM Director environment
IBM Director is designed to manage a complex environment that contains
numerous servers, desktop computers, workstations, mobile computers (notebook
computers), and assorted devices. IBM Director can manage up to 5000 Level-2
systems.
An IBM Director environment contains the following groups of hardware:
v One or more servers on which IBM Director Server is installed. Such servers are
called management servers.
v Servers, workstations, desktop computers, and mobile computers that are
managed by IBM Director. Such systems are called managed systems.
v Network devices, printers, or computers that have Simple Network Management
Protocol (SNMP) agents installed or embedded. Such devices are called SNMP
devices.
v Additional managed objects such as platforms and chassis. Collectively, all
managed systems, devices, and objects are referred to as managed objects.

cluster is a group of independent computer systems that work together as a
A
single logical system. A client interacts with a cluster as though it is a single server.
In other words, a cluster is a group of computers linked together in such a way
that they share and manage a set of resources that can support a number of users
at the same time.
The ServeRAID high-availability clustering solution is based on a two-server
cluster, where both servers can access the same storage devices, but only one
server at a time controls the storage devices shared by both servers. If one of the
two running servers fails, the remaining server automatically assumes control of
the shared resources managed by the failed server while still controlling its own
resources at the same time. The failed server can then be repaired offline without

managed by the failed server are still online to the clients.
When the failed server is operational again, it can be placed back into the cluster;
the resources are reallocated between the two servers and the cluster resumes
normal operation.
You will need clustering hardware and software to configure a cluster. You can

Understanding unattended mode
Unattended mode is a setting that alters how the ServeRAID Manager startup code
(that is, BIOS) handles failures during a system startup. Examples of possible
failures during the startup are the following:
v The BIOS cannot communicate with the controller.
v A physical drive state has changed.
v A logical drive state has changed.
You can set unattended mode: either Disabled or Enabled. The default is Disabled.
When unattended mode is disabled and the BIOS detects a failure, the system
remains at the recovery option screen and waits for the user to respond.
When unattended mode is enabled and the BIOS detects a failure, the system waits
for 30 seconds for the user to respond to the recovery options screen. If no user
Chapter 3. Using ServeRAID Manager 29
responds, the BIOS automatically selects the first recovery option in the list and
continues the system startup process. This mode is useful for remote systems
where a user is not present for system startups.
Consider carefully whether to enable unattended mode. Depending on how you
use the system, unattended mode might be undesirable.
For example, consider a system that includes an enclosure of multiple physical
drives. If the enclosure is turned off when you start the system, the BIOS reports a
drive failure. If unattended mode is enabled, the BIOS accepts a recovery option
that changes the configuration. When the system restarts with the enclosure turned
on, the configuration is no longer correct and the system no longer works as
originally configured.
You can change unattended mode with the ServeRAID Manager in bootable-CD
mode only.
Note: If you are configuring your system for clustering, you must enable
unattended mode. If you use the ServeRAID Manager to enable your system
for clustering, the ServeRAID Manager automatically enables unattended
mode.

Understanding RAID technology
Redundant array of independent disk (RAID) is the technology of grouping several
physical drives in a computer into an array that you can define as one or more
logical drives. Each logical drive appears to the operating system as a single drive.
This grouping technique greatly enhances logical-drive capacity and performance
beyond the physical limitations of a single physical drive.
When you group multiple physical drives 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
throughput (the amount of data processed 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 increase in
throughput, but also a decrease in response time. The combination of parallel
transfers and simultaneous responses to multiple requests enables disk arrays to
provide a high level of performance in network environments.

Understanding stripe-unit size
With RAID technology, data is striped across an array of physical drives. This
data-distribution scheme complements the way the operating system requests data.
The granularity at which data is stored on one drive of the array before subsequent
data is stored on the next drive of the array is called the stripe-unit size .
You can set the stripe-unit size to 8 KB, 16 KB, 32 KB, or 64 KB. You can maximize
the performance of your ServeRAID controller by setting the stripe-unit size to a
32 ServeRAID Manager Installation and User's Guide
value that is close to the size of the system I/O requests. 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 ServeRAID-7t, ServeRAID-8i, ServeRAID-8k/8k-l, and
HostRAID controllers do not support an 8 KB stripe-unit size. The ServeRAID-7t
ServeRAID-8i, and ServeRAID-8k/8k-l controllers support these additional
stripe-unit sizes: 128 KB, 256 KB, 512 KB, and 1024 KB.
The collection of stripe units, from the first drive of the array to the last drive of
the array, is called a stripe.
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.
You can set the stripe-unit size to 8 KB, 16 KB, 32 KB, or 64 KB. The default setting
is 8 KB data bytes.
v When the stripe-unit size is 8 KB or 16 KB, the maximum number of physical
drives in an array is 16.
v If you have a ServeRAID-3H or ServeRAID-3HB controller using ServeRAID
firmware (version 4.0, or later) and the stripe-unit size is 32 KB or 64 KB, the
maximum number of physical drives in an array is 16. Otherwise, when the
stripe-unit size is 32 KB or 64 KB, the maximum number of physical drives in an
array is 8.
v If you have a ServeRAID-4 controller and the stripe-unit size is set to 32 KB or
64 KB, the maximum number of physical drives in an array is 16.

Understanding RAID level-0
RAID level-0 stripes the data across all the drives in the array. This offers
substantial speed enhancement, but provides no data redundancy. RAID level-0
provides the largest storage capacity of the RAID levels that are offered, because
no room is taken for redundant data or data-parity storage.
RAID level-0 requires a minimum of one drive and, depending upon the level of
firmware and the stripe-unit size, supports a maximum of 8 or 16 drives.
For ServeRAID-8i, ServeRAID-8k/8k-l, ServeRAID-7t, and
HostRAID controllers, RAID level-0 requires a minimum of two drives.
The following illustration shows an example of a RAID level-0 logical drive.
Chapter 3. Using ServeRAID Manager 33
RAID level-0 example
Start with two physical drives.
Create an array using the two physical drives.
Then create a logical drive within that array.
The data is striped across the drives, creating blocks. Notice that the data is striped
across all the drives in the array, but no redundant data is stored.
A physical drive failure within the array results in loss of data in the logical drive
assigned RAID level-0, but only in that logical drive. If you have logical drives
assigned RAID level-1, 1E, 5, or 5E in the same array, they will not lose data.
If you have an array that contains only one physical drive, you can assign
Note:
only RAID level-0 to the logical drive in that array.
When you replace a failed drive, the controller can rebuild all the RAID level-1, 1E,
5, 5E, and 5EE logical drives automatically onto the replacement physical drive.
However, any data stored in a failed RAID level-0 logical drive is lost.
Although 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 this RAID level offers. Yo u
can use this logical drive to store data that you back up each day and can re-create
easily. You also might want to use a RAID level-0 logical drive when you require
maximum capacity.

Understanding RAID level-1
RAID level-1 uses data mirroring. Tw o physical drives are combined into an array,
and data is striped across the array. The first half of a stripe is the original data;
the second half of a stripe is a mirror (that is, a copy) of the data, but it is written
to the other drive in the RAID level-1 array.
RAID level-1 provides data redundancy and high levels of performance, but the
storage capacity is diminished. Because the data is mirrored, the capacity of the
logical drive when assigned RAID level-1 is 50% of the array capacity.
RAID level-1 requires two physical drives.
The following illustration shows an example of a RAID level-1 logical drive.
RAID level-1 example
Start with two physical drives.
Create an array using the two physical drives.
Chapter 3. Using ServeRAID Manager 35
Then create a logical drive within that array.
The data is striped across the drives, creating blocks. Notice that the data on the
drive on the right is a copy of the data on the drive on the left.
With RAID level-1, if one of the physical drives fails, the controller switches read
and write requests to the remaining functional drive in the RAID level-1 array.
Advantages and disadvantages
RAID level-1 offers the following advantages and disadvantages.

Understanding RAID level-1 Enhanced
RAID level-1 Enhanced (RAID level-1E) combines mirroring and data striping. This
RAID level stripes data and copies of the data across all of 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 array capacity.
RAID level-1E has a similar profile to RAID level-1; it provides data redundancy
and high levels of performance, but the storage capacity is diminished. However,
RAID level-1E allows a larger number of physical drives to be used.
RAID level-1E requires a minimum of three drives and, depending upon the level
of firmware and the stripe-unit size, supports a maximum of 8 or 16 drives.
36 ServeRAID Manager Installation and User's Guide
The following illustration is an example of a RAID level-1E logical drive.
RAID level-1 Enhanced example
Start with three physical drives.
Create an array using the physical drives.
Then create a logical drive within that array.
The data is striped across the drives, creating blocks. Notice that the stripe labeled
* is the data stripe and the stripe labeled ** is the copy of the preceding data
stripe. Also, notice that each block on the mirror stripe is shifted one drive.
With RAID level-1E, if one of the physical drives fails, the controller switches read
and write requests to the remaining functional drives in the RAID level-1E array.

Understanding RAID level-5
RAID level-5 stripes data and parity across all drives in the array.
RAID level-5 offers both data protection and increased throughput. When you
assign RAID level-5 to an array, the capacity of the array is reduced by the
capacity of one drive (for data-parity storage). RAID level-5 gives you higher
capacity than RAID level-1, but RAID level-1 offers better performance.
RAID level-5 requires a minimum of three drives and, depending upon the level of
firmware and the stripe-unit size, supports a maximum of 8 or 16 drives.
The following illustration is an example of a RAID level-5 logical drive.
RAID level-5 example
Start with four physical drives.
Create an array using three of the physical drives, leaving the fourth as a hot-spare
drive.
Then create a logical drive within that array.
The data is striped across the drives, creating blocks.
Notice that the storage of the data parity (denoted by *) also is striped, and it
shifts from drive to drive.
A parity block ( *) contains a representation of the data from the other blocks in
the same stripe. For example, the parity block in the first stripe contains data
representation of blocks 1 and 2.
38 ServeRAID Manager Installation and User's Guide
If a physical drive fails in the array, the data from the failed physical drive is
reconstructed onto the hot-spare drive.

Understanding RAID level-5 Enhanced
Note: This RAID level is not available on all controllers.
RAID level-5E is the same as RAID level-5 with a built-in spare drive. Like RAID
level-5, this RAID level stripes data and parity across all of the drives in the array.
RAID level-5E offers both data protection and increased throughput. When an
array is assigned RAID level-5E, the capacity of the logical drive is reduced by the
capacity of two physical drives in the array (one for parity and one for the spare).
Reading from and writing to four physical drives is more efficient than reading
from and writing to three physical drives and an idle hot spare. Therefore, RAID
level-5E provides a higher level of performance than RAID level-5.
Chapter 3. Using ServeRAID Manager 39
The spare drive is actually part of the RAID level-5E array, as shown in the
following example. With such a configuration, you cannot share the spare drive
with other arrays. If you want a spare drive for any other array, you must have
another spare drive for those arrays.
RAID level-5E requires a minimum of four drives and, depending upon the level
of firmware and the stripe-unit size, supports a maximum of 8 or 16 drives. RAID
level-5E is also firmware-specific.
Note: For RAID level-5E, you can have only one logical drive in an array. When
using RAID level-5E, you can have a maximum of seven logical drives on
the controller.
The following illustration is an example of a RAID level-5E logical drive.
RAID level-5 Enhanced example
Start with four physical drives.
Create an array using all four physical drives.
Then create a logical drive (labeled as 1) within the array. Notice that the
distributed spare drive is the free space (labeled as 2) shown below the logical
drive.
The data is striped across the drives, creating blocks in the logical drive. The
storage of the data parity (denoted by * ) is striped, and it shifts from drive to
drive as it does in RAID level-5. Notice that the spare drive is not striped.
If a physical drive fails in the array, the data from the failed drive is reconstructed.
The array undergoes compression, and the distributed spare drive becomes part of
the array. The logical drive remains RAID level-5E.
When you replace the failed drive, the data for the logical drive decompresses and
returns to the original striping scheme.
40 ServeRAID Manager Installation and User's Guide
If you use a RAID level-5E logical drive in a failover or cluster configuration, the
RAID level-5E logical drive will not failover while undergoing compression or
decompression.

Understanding RAID level-5EE
Note: This feature is not supported on all controllers.
RAID level-5EE is similar to RAID level-5E but with a more efficient distributed
spare and faster rebuild times. Like RAID level-5E, this RAID level stripes data
and parity across all of the drives in the array.
RAID level-5EE offers both data protection and increased throughput. When an
array is assigned RAID level-5EE, the capacity of the logical drive is reduced by
the capacity of two physical drives in the array: one for parity and one for the
spare.
The spare drive is part of the RAID level-5EE array. However, unlike RAID
level-5E, which uses contiguous free space for the spare, a RAID level-5EE spare is
interleaved with the parity blocks, as shown in the following example. This allows
Chapter 3. Using ServeRAID Manager 41
data to be reconstructed more quickly if a physical drive in the array fails. With
such a configuration, you cannot share the spare drive with other arrays. If you
want a spare drive for any other array, you must have another spare drive for
those arrays.
RAID level-5EE requires a minimum of four drives and, depending upon the level
of firmware and the stripe-unit size, supports a maximum of 8 or 16 drives. RAID
level-5EE is also firmware-specific.
Note: For RAID level-5EE, you can have only one logical drive in an array.
The following illustration is an example of a RAID level-5EE logical drive.
RAID level-5EE example
Start with four physical drives.
Create an array using all four physical drives.
Then create a logical drive within the array.
The data is striped across the drives, creating blocks in the logical drive. The
storage of the data parity (denoted by *) is striped, and it shifts from drive to
drive as it does in RAID level-5E. The spare drive (denoted by S) is interleaved
with the parity blocks, and it also shifts from drive to drive.
If a physical drive fails in the array, the data from the failed drive is reconstructed.
The array undergoes compaction, and the distributed spare drive becomes part of
the array. The logical drive remains RAID level-5EE.

Understanding RAID level-6
RAID level-6 is similar to RAID level-5 but with two sets of parity information
instead of one. RAID level-6 stripes blocks of data and parity across all drives in
the array like RAID level-5, but adds a second set of parity information for each
block of data.
When you assign RAID level-6 to an array, the capacity of the array is reduced for
data-parity storage (the exact amount depends on the size of the drives in the
array). The second set of parity information is added to improve fault tolerance.
RAID level-6 can handle two simultaneous drive failures, where other single RAID
levels can handle, at most, only one.
RAID level-6 requires a minimum of four drives and supports a maximum of 16
drives. The maximum stripe-unit size depends on the number of drives in the
array.
The following illustration is an example of a RAID level-6 logical drive.
Chapter 3. Using ServeRAID Manager 43
RAID level-6 example
Start with six physical drives.
Create a logical drive using four physical drives, leaving two for hot spare drives.
The data is striped across the drives, creating blocks in the logical drive. The
storage of the data parity (denoted by * and **) is striped, and it shifts from drive
to drive as it does in RAID level-5.
If a physical drive fails in the array, the logical drive is degraded but remains fault
tolerant.
If a second physical drive fails in the array, the data from the failed drives are
reconstructed onto the hot-spare drives, and the data for the logical drive return to
the original striping scheme.

Understanding RAID level-x0
Note: RAID level-x0 is not available on all controllers.
RAID level-x0 refers to RAID level-00, 10, 1E0, 50 and 60. RAID level-x0 uses an
array of arrays, or a spanned array. The operating system uses the spanned array
logical drive in the same way as a regular array logical drive.
RAID level-x0 allows more physical drives in an array. The benefits of doing so are
larger logical drives, increased performance, and increased reliability. RAID level-0,
10, 1E, 5, 5E, and 6 cannot use more than 16 physical drives in an array; however,
RAID level-1E0, 50, and 60 support 60 to 128 drives.
RAID level-x0 requires a minimum of two drives and supports a maximum of 60
to 128 drives, depending on the controller.
The following illustration is an example of a RAID level-10 logical drive.
Chapter 3. Using ServeRAID Manager 45
RAID level-10 example
Start with six physical drives.
Create three arrays (labeled A, B, and C), each array using two physical drives.
Then create a spanned array (labeled as *) that spans the three arrays.
A sub-logical drive is created within each array (A, B, and C). Then the data is
striped across the physical drives in the array, creating blocks.
Notice that, in each array, the data on the drive on the right is a copy of the data
on the drive on the left. This is because the sub-logical drives (A, B, and C) are
RAID level-1 in a RAID level-10 implementation (see the following table).
Then create a logical drive within the spanned array (*).
The data is striped across this logical drive, creating blocks ( 1- 12). Notice that
none of these blocks are redundant. This is because the logical drive is RAID
level-0 in a RAID level-x0 implementation (see the following table).
RAID level Sub-logical drive Spanned array logical drive

RAID level Sub-logical drive Spanned array logical drive
60 RAID level-6 RAID level-0
With RAID level-10, 1E0, and 50, if one of the physical drives fails in a sub-logical
drive, the ServeRAID controller switches read and write requests to the remaining
functional drives in the sub-logical drive. With RAID level-60, if one or two of the
physical drives fails in a sub-logical drive, the ServeRAID controller switches read
and write requests to the remaining functional drives in the sub-logical drive. With
RAID level-00, a physical drive failure within the sub-logical drive results in loss of
data.
Advantages and disadvantages
RAID level-x0 offers the following advantages and disadvantages.
Advantages Disadvantages
v Supports up to 60 physical drives on SCSI
controllers
v Supports up to 128 physical drives on

For ServeRAID SAS controllers (8i/8k/8k-l) and the ServeRAID-7t S ATA controller,
the ServeRAID Manager supports the following RAID volume types:
v Simple Volume - a single disk drive or segment; not redundant.
v Spanned Volume - two or more disk drives or segment with the same or
different capacity, connected end-to-end. A spanned volume offers no
redundancy or performance advantage over a single drive.
v RAID Volume - two or more logical drives with the same RAID level,
connected end-to-end. The logical drives may have the same or different
capacity and are not striped together; they may be redundant, depending on the
RAID level.
Notes:
Chapter 3. Using ServeRAID Manager 47
– You must create the individual logical drives before you create a
RAID Volume. Use the Configuration wizard to create the logical
drives; then, run the Configuration wizard again to create the RAID
Volume.
– When you create a RAID Volume, the ServeRAID Manager replaces
the individual logical drives with a single RAID Volume icon in the
Logical devices view; then, it reports the logical drives as deleted in
the event viewer. The event message is normal and does not indicate a
loss of data.

or segment used for storage in a RAID system; it is not redundant.
Complete the following steps to create a simple volume:
1. In the Physical devices view, click
(online physical drive).
2. Right-click Create simple volume.
3. Click Yes to confirm.

Selecting a RAID level and tuning performance
Disk arrays are used to improve performance and reliability. The amount of
improvement depends on the application programs that you run on the server and
the RAID levels that you assign to the logical drive.
Each RAID level provides different levels of fault-tolerance (data redundancy),
utilization of physical drive capacity, and read and write performance. In addition,
the RAID levels differ in regard to the minimum and maximum number of
physical drives that are supported.
When selecting a RAID level for your system, consider the following factors.

Example: Total disk capacity
Physical drives in an array can be of different capacities (1 GB, or 2 GB, for
example). The sum of the physical drives’ capacity grouped in an array is the total
disk capacity.
For example, if you group two 2 GB drives and one 3 GB drive into an array, the
total disk capacity is the 7 GB physically available.
2 GB 2 GB 3 GB
50 ServeRAID Manager Installation and User's Guide
Similarly, if you group three 2 GB drives and 1 GB drive into an array, the total
disk capacity is the 7 GB physically available.
More information
v Example: Usable and unusable capacity
Example: Usable and unusable capacity
Physical drive capacities influence the way you create arrays and logical drives.
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 physical
drive.
For example, if you group two 2 GB drives and one 3 GB drive into an array, the
usable capacity of the array is 2 GB times 3, or 6 GB, not the 7 GB physically
available. The 7 GB is the total disk capacity. In the following diagram, usable
capacity is labeled as 1 and unusable capacity is labeled as 2.
2 GB 2 GB 3 GB
Similarly, if you group three 2 GB drives and 1 GB drive into an array, the usable
capacity of that array is 4 GB, not the 7 GB physically available. The 7 GB is the
total disk capacity. The remaining capacity left on the three 2 GB drive is unusable
capacity.
The optimal way to create arrays is to use physical drives that have the same
capacity. Doing so avoids unusable capacity
For the ServeRAID-8i, ServeRAID-8k/8k-l, and ServeRAID-7t controllers, usable
capacity is the same as the total disk capacity. That is, you can use the remaining
space to define another logical drive. The segments that make up the logical drive
must be the same size on each physical drive. For example, you can group two 1
GB segments with the remaining space from the previous example to define a 3 GB
logical drive. In the following diagram, the new logical drive is labeled 2; 4 GB of
usable capacity remain, 2 GB on each drive, labeled 3.

before configuring ServeRAID.
In the Configuration wizard, you can choose from two paths to configure your
ServeRAID subsystem:
v Click Express configuration for a quick and easy path for you to automatically
configure your ServeRAID controller. This path creates the most efficient
ServeRAID configuration based on the number and capacity of the ready
physical drives available in your system. If four or more ready drives of the
same capacity are available, this choice also will define a hot-spare drive.
Express configuration does the following:
– Creates arrays by grouping together same-sized physical drives.
– Creates one logical drive per array up to 2 terabytes (TB) maximum.
– Assigns a RAID level based on the number of physical drives in an array:
- An array with a single physical drive is assigned RAID level-0.
- An array with two physical drives is assigned RAID level-1.
- An array with three or more physical drives is assigned RAID level-5.
© Copyright IBM Corp. 1999, 2006 63
Note: If the physical drive size exceeds 2TB, Express configuration removes
drives until the size is less than 2 TB. It creates an additional array
with the left-over drive(s).
– Designates a hot-spare drive for the controller. If one or more arrays has four
or more physical drives, the largest-sized drive from those arrays will be
designated the hot-spare drive.

configure your controller. This path creates the most efficient configuration based
on the number and capacity of the ready physical drives available in your
system. If four or more ready drives of the same capacity are available, this
choice also will define a hot-spare drive.
Express configuration does the following:
– Creates one logical drive, up to 2 terabytes (TB) maximum, by grouping
together same-sized physical drives.
Note: If the physical drive size exceeds 2 terabytes (TB), Express
configuration removes drives until the size is less than 2 terabytes (TB).
It creates an additional logical drive with the left-over drive(s).
– Assigns a RAID level based on the number of available physical drives:
- A logical drive with a single physical drive is assigned RAID level-0.
- A logical drive with two physical drives is assigned RAID level-1.
- A logical drive with three physical drives is assigned RAID level-5.
For HostRAID controllers, Express configuration creates a RAID level-1
logical drive.
– Designates a hot-spare drive for the controller. If four or more ready drives
are available, the largest drive will be designated the hot-spare drive.

Example: Express configuration: If your server contains the following:
v One 1024 MB ready drive,
v Two 2150 MB ready drives,
v 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.
Notes:
1. 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.
2. 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. Array A is not
redundant, therefore a hot-spare drive is not used.

Configuring NetWare user authentication
NetWare user authentication may be configured in one of two ways: out-of-box
authentication and NDS authentication. The two methods are mutually exclusive.
Out-of-box authentication
Out-of-box authentication works as follows:
v Administrative access is exclusively granted to the ‘Admin’ user account, which
must be defined within the NetWare Bindery context of the server running the
ServeRAID Manager agent.
v User access is granted to all Bindery and NetWare Directory Services (NDS) user
accounts. For NDS users, the user account must reside within the same tree as
the server running the ServeRAID Manager agent.
logging into the ServeRAID Manager, NDS users must provide the fully
When
distinguished account name.
NDS authentication
NDS authentication is based on NDS group membership. To set up NDS group
membership, create and populate a NDS group for storage administration. After
you install the ServeRAID Manager, edit the ServeRAID Manager agent properties
file to restrict authentication to the new group.
For example:
1. Choose the group name ″.CN=StorageAdmins.O=Acme″.
Note: The group must reside within the same NDS tree as the server running
the ServeRAID Manager agent.
2. Using the Novell Administration utility, add the appropriate users to the new
group.
3. Add the following entry to the SYS:\RAIDMAN\RaidAgent.pps file:
agent.group.NetWareStorageAdmin=< fully distinguished group name>The
new entry should look like this :
agent.group.NetWareStorageAdmin=.CN=StorageAdmins.O=Acme
4. Restart the server.
Limited
user access is granted to all NDS user accounts.

Attention: Do not attempt a hot-replace operation on Windows 2000, Windows
Server 2003, or NetWare by hot-removing a failed controller and then hot-adding a
new controller. Loss of data can occur. If a controller fails on these operating
systems, you must shut down the server to replace the controller.

reestablish the original configuration on the new controller.
If you are replacing a controller in a cluster environment, you must first configure
the cluster parameters by using the ″ Configure for clustering″ action. The cluster
parameters are the following:
v The controller name
v The partner controller name
v The SCSI initiator IDs
After you have configured these parameters, you can use ″Copy configuration
from drives″ to copy the configuration from only the non-shared drives into the
new controller.
