RAID Overview
This section provides a brief overview of the types of RAID configurations that Embedded RAID supports.
The first step in creating a RAID storage configuration is to configure drives in drive groups (also known as arrays). As
defined for Embedded RAID, a drive group is a group of one to eight physical disks that is seen by the host computer
system as one large disk drive, or virtual drive. Only one RAID level can be assigned to a drive group.




A RAID 0 drive group consists of one to eight drives.
A RAID 1 drive group consists of two drives.
A RAID 5 drive group consists of three to eight drives.
A RAID 10 drive group consists of four, six, or eight drives.
NOTE
Some hardware configurations do not support eight drives.
Depending on the hardware, the actual maximum number of drives
for RAID 0, RAID 5 and RAID 10 drive groups can be fewer than eight.
You can use any of these three strategies when creating RAID drive groups and virtual drives:


Maximize Fault Tolerance – You can maximize fault tolerance to protect against loss of data by creating a RAID 1
drive group with mirroring. All data is written to the primary drive in the drive group and is also written (mirrored)
to a second drive.
Maximize Virtual Drive Performance – You can maximize virtual drive performance by creating a RAID 0 drive
group with striping. Data is broken into segments and can be simultaneously written to or read from several
different stripes on several different drives in the drive group.
RAID 10 drive groups combine both striping and mirroring to provide high data transfer rates and
data redundancy.

Maximize Storage Capacity – You can maximize storage capacity when selecting a RAID level. Striping alone
(RAID 0) requires less storage space than mirrored data (RAID 1) or distributed parity (RAID 5). RAID 5, which
provides redundancy for one drive failure without duplicating the contents of entire drives, requires less space
than RAID 1.

1.2.1
RAID Overview
RAID 0 Description
RAID 0 provides disk striping across all drives in the drive group. RAID 0 does not provide any data redundancy, but
does offer the best performance of any RAID level. RAID 0 breaks up data into smaller segments called strips, and then
stripes the data segments across each drive in the drive group. The size of each data segment is determined by the
strip size, which is 64 KB.
NOTE
It is possible to create each disk as a single-drive RAID 0 drive group.
However, spanning across single drive RAID 0 drive groups is
not supported.
By breaking up a large file into smaller segments, and writing or reading from several drives at once, the Embedded
MegaRAID Software utility can read or write the file faster. This feature makes RAID 0 ideal for applications that require
high bandwidth but do not require fault tolerance.
Uses
Provides high data throughput, especially for large files; any environment that does not require fault tolerance
Strong Points
Provides increased data throughput for large files; no capacity loss penalty for parity
Weak Points
Does not provide fault tolerance; all data lost if any drive fails
Drives
One to eight

RAID 1 Description
RAID 1 duplicates all data from one drive to a second drive. RAID 1 provides complete data redundancy, but at the cost
of doubling the required data storage capacity.
Uses
Databases or any other mission critical environment that requires fault tolerance
Strong Points
Provides complete data redundancy; RAID 1 is ideal for any application that requires fault tolerance
Weak Points
Requires twice as many drives; performance is impaired during drive rebuilds
Drives

Segment 3 Duplicated
Segment 4 Duplicated
RAID 5 Description
RAID 5 includes disk striping at the block level and parity. Parity is the data’s property of being odd or even, and parity
checking is used to detect errors in the data. In RAID 5, the parity information is distributed to all drives. RAID 5 is best
suited for networks that perform a lot of small input/output (I/O) transactions simultaneously.
NOTE
RAID 5 is a premium feature. You might need to install a software key
to enable RAID 5. The key you need depends on your supplier. Contact
your supplier for more information.
RAID 5 addresses the bottleneck issue for random I/O operations. Because each drive contains both data and parity,
numerous writes can take place concurrently.
Uses
Provides high data throughput. Use RAID 5 for transaction processing applications because each drive can read
and write independently. If a drive fails, the RAID controller uses the parity drive to recreate all missing
information. Use also for office automation and online customer service that requires fault tolerance. Use for
any application that has high read request rates but low write request rates.
Strong Points
Provides data redundancy, high read rates, and good performance in most environments. Provides redundancy
with lowest loss of capacity.
Weak Points
Not well suited to tasks requiring lot of small writes. Drive performance will be reduced if a drive is being rebuilt
or a background initialization is in progress. Environments with few processes do not perform as well because
the RAID overhead is not offset by the performance gains in handling simultaneous processes.
Drives
Three to eight.

1.2.4
RAID Overview
RAID 10 Description
RAID 10, a combination of RAID 1 and RAID 0, has mirrored drives. It breaks up data into smaller blocks, and then
stripes the blocks of data to each RAID 1 RAID set. Each RAID 1 RAID set then duplicates its data to its other drive. The
size of each block is determined by the strip size parameter, which is 64 KB. RAID 10 can sustain one drive failure in
each drive group while maintaining data integrity.
NOTE
On a RAID 10 drive group, you can create only one virtual drive, and
that virtual drive must occupy the entire space of the RAID 10
drive group.
Uses
Works best for data storage that must have 100 percent redundancy of RAID 1 (mirrored drive groups) and that
also needs the enhanced I/O performance of RAID 0 (striped drive groups); RAID 10 works well for
medium-sized databases or any environment that requires a higher degree of fault tolerance and moderate to
medium capacity
Strong Points
Provides both high data transfer rates and complete data redundancy
Weak Points
Requires twice as many drives
Drives
Four, six, or eight

Linux Driver Installation
Updating the Red Hat Linux Driver (Generic)
Perform the following steps to update the Red Hat Linux driver or to install the Red Hat Linux driver in an existing
system booted from a standard SATA drive or systems with the Embedded Software RAID stack.
1.
Boot the system with the Red Hat Linux Installation CD from the primary controller or disk.
The Red Hat Introductory screen appears.
2.
Mount the driver update diskette (DUD) using the following command:
#mount /dev/fd0 /mnt/floppy
3.
Unzip the modules.cgz file that is on the DUD to get driver images for different Red Hat operating systems:
#mkdir -p /home/megasr
#cd /home/megasr
#cp /mnt/floppy/modules.cgz 
#gunizip -S .cgz modules.cgz
This action generates a new file named modules:
#cpio -ivd < modules
This action provides the following driver images:
<kernel version>/megasr.o
<kernel version>smp/megasr.o
<kernel version>BOOT/megasr.o
4.
Update the Megasr driver module for the required kernels using the following commands:
#cd /home/megasr
If the /lib/modules/<kernel version>/update/ directory is present, use the following command:
# cp <kernel version>/megasr.[o/ko]
/lib/modules/<kernel version>/update/megasr.[o/ko]
If the /lib/modules/<kernel version>/update/ directory is not present, use the following command:
# cp <kernel version>/megasr.[o/ko]
/lib/modules/<kernel version>
/kernel/drivers/scsi/megasr.[o/ko]
5.
Create a Megasr driver entry in the configuration file. The Red Hat configuration file is /etc/modules.conf.
If the Megasr entry is not present in /etc/modules.conf, add the following line:
alias scsi_hostadapter megasr
If the ahci SCSI driver entry (located on the following paragraph) is present in /etc/modules.conf, remove
it. It must be removed; otherwise, the ahci driver would take control of the RAID controller without checking the
subsystem device or Vendor ID. The ahci SCSI driver entry is the following:
alias scsi_hostadapter ahci
6.
Create a new initrd image for the required kernel.
Red Hat installation uses the mk_initrd command to create an initrd image. The following command
creates an initrd image for the <kernel version>smp kernel in the boot directory. Refer to the
mk_initrd man page for more information. The command is:
#mkinitrd /boot/initrd<kernel version>smp.img.new
<kernel version>smp

Modify the lilo.conf/grub.conf file by adding newly created initrd images as new entries in the
/etc/lilo.conf file.
The suggested method is to copy an existing lilo entry in the file and paste it as a new one. Then modify its
kernel image name, initrd image name, and label name.
Sample Lilo Entry
image=/boot/vmlinux-<kernel version>smp label=linuxnew
initrd=/boot/initrd-<kernel version>smp.img.new 
read-only appended=root=LABEL=/ ”
Sample Grub Entry
title Red Hat Linux (<kernel version> with Megasr driver)
root (hd0,0)
kernel /vmlinuz-<kernel version> ro root=LABEL=/
initrd /initrd-<kernel version>.img.new
8.
Update the boot loader. If the boot loader is Lilo, run the lilo command to update the boot loader:
#lilo
9.
2.2.5
Reboot the system to the new boot loader entry.
Enabling RAID Mode during Red Hat Linux 5 Driver Installation
This section documents how to load the RHEL5 operating system drivers so the drivers recognize RAID mode and
support RAID 0, 1, 5, and 10 functionality.
On servers with on-board, AHCI-based SATA controllers, the controllers can be set to HBA mode or RAID mode using
the system BIOS. The system BIOS changes the PCI sub-system IDs based on the selected mode. The MegaRAID
software RAID (megasr) driver can be set to RAID mode for the AHCI-based SATA controllers and support RAID levels 0,
1, 5, and 10. The megasr driver considers all four PCI IDs to decide whether the driver supports the controller.
In Red Hat Enterprise Linux 5 (RHEL 5), however, the native AHCI driver Linux kernel looks only at the vendor ID and
the device ID, and ignores the subsystem IDs. As a result, RHEL 5 ignores the RAID mode, and does not support RAID
mode. The RHEL 5 installation process loads the native AHCI driver even when the megasr DUD is present. Also, the
process includes AHCI in the initrd (during which a temporary file system is loaded into memory in the Linux kernel
boot process).
Perform the following steps to load the RHEL5 operating system drivers so they recognize the RAID mode.
1.
Use the noprobe option at the installation kernel boot prompt, in addition to the dd option.
This step prevents AHCI from loading ahead of megasr, allowing you to install RHEL 5 on the megasr virtual drive.
The following string is an example of the noprobe option:
boot: linux dd noprobe=ata1 noprobe=ata2 noprobe=ata3 noprobe=ata4
At the last installation step, after all the packages are installed, RHEL5 prompts you to reboot. At this point, the
initrd is built with the AHCI driver. You must add megasr and delete ahci from initrd before you reboot.
2.
Press Ctrl+Alt+F2.
This step takes you to a text console prompt.
3.
Before you reboot, perform these steps:
a.
b.
c.
d.
e.
f.
Press Ctrl+Alt+F2 to go to the text console.
Enter the command: cat /proc/partitions to get the major and minor number of the floppy drive.
Enter the command: mknod /dev/sd(x) b major minor
Create a directory (for example, mkdir swr).
Mount the floppy drive to that directory with the mount /dev/sd(x) swr command.
Run the ./replaceachi.sh script.

Set Boot Devices
Selects the virtual drive to use as the boot device.
Rebuild Rate
The percentage of central processing unit (CPU) resources devoted to rebuilding data onto a
new drive after a drive in a storage configuration has failed. The default value is 30 percent.
Background Initialization (BGI)
Rate
Background initialization is a check for media errors on the drives when you create a virtual
drive. It is an automatic operation that starts five minutes after you create the virtual drive. This
check ensures that striped data segments are the same on all of the drives in the drive group.
The default value is 30 percent.
Consistency Check Rate
A consistency check is an operation that verifies that all stripes in a virtual drive with a
redundant RAID level are consistent and that automatically fixes any errors. The consistency
check rate is the rate at which consistency check operations are run on a computer system. The
default value is 30 percent.
Disk Coercion
Drive coercion is a tool for forcing drives of varying capacities to the same capacity so they can
be used in a drive group. The coercion mode options are None, 128MB-way, and 1GB-way. The
number you choose depends on how much the drives from various vendors vary in their
actual size.
Read Ahead
When disk Read Ahead is On, extra data is read sequentially ahead of the data that is actually
requested, and this extra data is stored in cache memory. If the additional read-ahead data is
then requested, it can be read faster from the cache than from the disk directly. This setting
speeds up reads for sequential data, but there is little improvement when accessing
random data.
Disk WC
You can disable the disk write cache option when you create a virtual drive, but you can enable
this option later using the configuration utilities. When the disk Write Cache is On, a write
transaction is considered to be complete when all the data has been written to the disk cache.
When disk Write Cache is Off, the write transaction is complete only when the data has been
written to the disk.
Auto Rebuild
Auto-rebuild allows a failed drive to be replaced and the data automatically rebuilt by
hot-swapping the drive in the same drive bay. The RAID drive group continues to handle
requests while the rebuild occurs.

Use drives with the same capacity when you create a storage configuration. If you use drives with different capacities
in the same drive group, the CU limits each drive to the capacity of the smallest drive.
The number of physical drives in a specific array determines the possible RAID levels that you can implement with
the array.




RAID 0 requires from one to eight physical drives.
RAID 1 requires two physical drives.
RAID 5 required three to eight physical drives.
RAID 10 requires four, six, or eight physical drives.
NOTE
The stripe size is read-only. You cannot change the settings for
this property.
Follow these steps to access the Virtual Drive Management screen and create a virtual drive configuration.

Select Drives From – The sources that you can use to select drives for the virtual drive. The options are
Unconfigured Capacity and Free Capacity.
Select Drives – Select this button and a screen appears that lists Unconfigured Good drives or free capacity,
depending on the value you selected in the Select Drive From field.
Virtual Drive Name – Enter the name of the virtual drive.
Virtual Drive Size – Enter the capacity of the virtual drive. Normally, this value is the full capacity of the drive.
You can specify a smaller capacity if you want to create other virtual drives on the same drive group.
Virtual Drive Size Unit – Enter the unit of capacity you want to use for the virtual drive. The options are MB,
GB, and TB.
Stripe Size – A stripe consists of the data segments that the RAID controller writes across multiple drives, not
including parity drives. The default is 64 KB. This setting is read-only.
Read Ahead – When disk Read Ahead is On, extra data is read sequentially ahead of the data that is actually
requested, and this extra data is stored in cache memory. If the additional read-ahead data is then requested,
it can be read faster from the cache than from the disk directly. This setting speeds up reads for sequential
data, but there is little improvement when accessing random data.

Managing Virtual Drives
Disk WC – You can disable the disk write cache option when you create a virtual drive, but you can enable
this option later using the configuration utilities. When the disk Write Cache is On, a write transaction is
considered to be complete when all the data has been written to the disk cache. When disk Write Cache is Off,
the write transaction is complete only when the data has been written to the disk.
— Disable Background Initialization – Use this option to select the amount of system resources dedicated to
background initialization of virtual drives connected to the selected controller.

MegaCLI CT Overview
Chapter 5: MegaCLI Command Tool
This chapter describes the commands for the MegaCLI Command Tool and how to use them.
The MegaCLI Command Tool (CT) is a command line interface application that you can use to configure and maintain
storage configurations created with Embedded RAID.
NOTE
5.1
The MegaCLI CT utility runs in the Microsoft® Windows® operating
environment and the Linux™ operating environment. For DOS, the
utility is called MegaDCLI CT, and it supports a subset of the full
command set.
MegaCLI CT Overview
MegaCLI CT and MegaDCLI CT are command line interface applications you can use to configure and manage storage
configurations under Embedded RAID. You can use these command tools to perform the following tasks:

Exception Handling
Set Virtual Drive Properties (-LDSetProp)
Virtual Drive Reconstruction (-LDRecon)
NOTE
The Embedded RAID utility does not support Write Policy, Read Policy,
or I/O Policy. Software RAID supports only enabling and disabling the
drive’s write cache and read-ahead functions.
NOTE
MegaCLI CT for Embedded RAID does not support the concept of disk
enclosures, except for a default Enclosure 0 (E0). Some of the
commands support an E0:Sn syntax that enables you to specify a drive
in a particular “slot” in this default enclosure.
Exception Handling
MegaCLI CT exits with exit code 0 for all successful operations. In case of failure, it exits with exit code 1 to 255,
depending on the failure conditions. For example, assume that a rebuild is started on three physical drives. MegaCLI
CT successfully starts rebuilding the first drive but fails to start rebuilding the second drive. If this happens, MegaCLI
CT does not attempt to start rebuilding the third drive; instead, it exits with an error exit code. In this case, the error
code is EXIT_ERR_START_RBLD. So even if the command was partially successful, an error code is still generated.
Some operations, such as GetNumberOfAdapters or GetNumberofLogicaldrives return with the actual
number of controllers or virtual drives. These return values are special cases and do not reflect any error conditions
based on the return code, which in these cases contains meaningful values.

Configuration Commands
Configuration Commands
You can use the commands in this section to create storage configurations.
5.7.1
Add RAID 0, RAID 1, or RAID 5 Configuration
Use the command in Table 15 to add a RAID level 0, 1, or 5 configuration to the existing configuration on the selected
adapter. For RAID level 10, see Section 5.7.3, Add RAID 10 Configuration, on page 75.
Table 15 Add RAID 0, 1, or 5 Configuration
Syntax
MegaCLI –CfgLDAdd -R0|-R1|-R5[[E0]:Sn] [-szXXXXXXXX [-szYYYYYYYY [...]]]
[-strpszM] [-Hsp[E5:S5,...]] [–afterLdX] -aN
Description
Adds a RAID level 0, 1 or 5 configuration to a specified adapter. Even if no configuration is present, you
have the option to write the configuration to the adapter.

–Rx[[E0]:Sn] – Used to specify the RAID level and the physical drive enclosure/slot numbers for a
drive group.
NOTE No enclosure number is needed for simple swap configurations, in which a drive is not part of an
enclosure. For example, in a RAID 1 configuration with a drive in slot 2 that is not in an enclosure, and a
drive in an enclosure in slot 3, the syntax is -R1[:2,1:3].




–strpszM – Used (optionally) to specify a stripe size. You can set the stripe size to 64 KB.
–Hsp[Ex:Sx,…] – Used to create a global hot spare, with physical drive enclosure/slot
numbers specified.
–szXXXX – Used to specify the size of a virtual drive, where XXXX is a decimal number of MB.
However, the actual size of the virtual drive might be smaller, because the driver requires the number
of blocks from physical drives in each virtual drive to be aligned to the stripe size. This option can also
be used to create a configuration on the free space available in the array.
-AfterLdX – Used to specify which free slot should be used (optional). By default, MegaCLI CT uses
the first free slot available in the array. This option has no meaning if the array is not already used
for configuration.

NOTE
The MegaCLI CT does not support spanning across these single-drive
RAID 0 configurations.
Table 16 Configure Each Disk as RAID 0
5.7.3
Syntax
MegaCLI –CfgEachDskRAID0 [{WT | WB}] [{NORA | RA | ADRA}] [{Direct |
Cached}] [{-strpszM} -aN|-a0,1,2|-aALL
Description
Configures each physical disk in Unconfigured-Good state as RAID 0 on this controller.
The options {WT |WB} {NORA | RA | ADRA} {Direct | Cached} must be entered in the
sequence that is shown.

WT – Used to select Write-through caching, in which a write transaction is considered to be complete
when all the data has been written to the disk cache.

WB – Used to select Write-back caching, in which the write transaction is complete only when the
data has been written to the disk.

NORA – Used to select Normal Read Ahead caching, which specifies that the controller reads only the
requested data and does not read ahead for the current virtual drive.

RA – Used to select Read Ahead caching, which specifies that data is read sequentially ahead of the
data that is actually requested and is stored in a cache. If the additional read-ahead data is then
requested, it can be read faster from the cache than from the disk directly. Read-Ahead supplies
sequential data faster, but is not as effective when accessing random data.

ADRA – Used to select Adaptive Read Ahead, which specifies that the controller begins using Read
Ahead caching if the two most recent disk accesses occurred in sequential sectors. If all read requests
are random, the algorithm reverts to No Read Ahead; however, all requests are still evaluated for
possible sequential operation.
If you select Read Ahead, there is a danger that data could be lost if the power fails before the cached
data is written to disk.

Direct – Used to specify that the controller does not buffer reads in cache memory. Data is
transferred to cache and the host concurrently. If the same data block is read again, it comes from
cache memory.

Cached – Used to specify that the controller buffers all reads in cache memory.

{-strpszM} – Used to specify the size of the segments written to each drive in the configuration.
You can set the stripe size to 64 KB.
Add RAID 10 Configuration
Use the command in Table 17 to add a RAID 10 configuration to the existing configuration on the selected adapter.
For RAID levels 0, 1, or 5, see Section 5.7.1, Add RAID 0, RAID 1, or RAID 5 Configuration, on page 74.
NOTE
On a RAID 10 array, you can create only one virtual drive, and that
virtual drive must occupy the entire space of the RAID 10 array.
Table 17 Add RAID 10 Configuration
Syntax
MegaCLI –CfgSpanAdd -R10| –Array0[E0:Sn] –Array1[E0:Sn] [...] [{WT | WB}]
[{NORA | RA | ADRA}] [{Direct | Cached}] [{-strpszM}] -aN
Description
Creates a RAID level 10 (spanned) configuration from the specified arrays. Even if no configuration is
present, you must use this option to write the configuration to the adapter.
Multiple arrays are specified using the –ArrayX[E0:Sn,...] option. (Note that X starts from 0, not 1.)
All the arrays must have the same number of physical drives. At least two arrays must be provided. The
options {WT |WB} {NORA | RA | ADRA} {Direct | Cached} must be entered in the sequence
that is shown.

Overview
Chapter 6: MegaRAID Storage Manager Overview and Installation
MegaRAID Storage Manager (MSM) is a configuration and monitoring utility used with Embedded MegaRAID
Software. This chapter provides a brief overview of the MegaRAID Storage Manager and explains how to install it on
the supported operating systems.
6.1
Overview
MegaRAID Storage Manager can be installed either on the local system which contains the MegaRAID controllers that
you wish to monitor, or on a remote system such as a workstation or a laptop with network connectivity to the system
you wish to monitor. Because of this, the system hardware and software requirements for installing MegaRAID Storage
Manager might differ from the system requirements for the MegaRAID controller(s) you are using.
MegaRAID Storage Manager enables you to configure, monitor, and maintain storage configurations created under
Embedded RAID. The MegaRAID Storage Manager graphical user interface (GUI) makes it easy for you to create and
manage storage configurations.
NOTE
6.1.1
MegaRAID Storage Manager can manage a wide range of MegaRAID
controllers. Some MegaRAID Storage Manager features are not
applicable for Embedded RAID.
Creating Storage Configurations
MegaRAID Storage Manager enables you to easily configure the controllers, disk drives, and virtual disks on your
workstation or server. The Simple Configuration mode and the Advanced Configuration mode greatly simplify the
process of creating drive groups and virtual drives. You can use these configuration modes to create the best possible
configuration with the available hardware.
You can create the following types of configurations:


Simple configuration specifies a limited number of settings and has the system select drives for you. This option
is the easiest way to create a virtual drive.
Advanced configuration lets you choose additional settings and customize virtual drive creation. This option
provides greater flexibility when creating virtual drives for your specific requirements.
See Section 7.1, Creating a New Storage Configuration, on page 90, for the procedures used to create
storage configurations.
6.1.2
Monitoring Storage Devices
MegaRAID Storage Manager displays the status of virtual disks, physical disks, and other storage devices on the
workstation or server that you are monitoring. System errors and events are recorded in an event log file and are
displayed on the screen. Special device icons appear on the screen to notify you of disk failures and other events that
require immediate attention.
6.1.3
Maintaining Storage Configurations
You can use MegaRAID Storage Manager to perform system maintenance tasks such as running consistency checks
on arrays that support redundancy.

Hardware and Software Requirements
Hardware and Software Requirements
MegaRAID Storage Manager has the following hardware requirements:


PC-compatible computer with an IA-32 (32-bit) Intel Architecture processor or an EM64T (64-bit) processor and at
least 128 MB of system memory
NOTE
LSI recommends that you use at least 1 GB of system memory.
Physical drive with at least 50 MB of available free space
MegaRAID Storage Manager supports these operating systems:





Microsoft Windows Server 2003, 2008, and 2008R2
Microsoft Windows Workstation 7
Microsoft Windows Vista Workstation
Red Hat Enterprise Linux (RHEL) 5 and 6
SuSE Linux Enterprise Server (SLES) 10 and 11, with latest updates and service packs
NOTE
MegaRAID Storage Manager supports the RHEL6 operating system
(OS) with a few prerequisites. By nature, the RHEL6 OS default
installation deploys only limited inbox libraries though it is shipped in
the CD image for the full installation. This design from the RHEL6 OS
adds an overhead for the Java® application programming users, and a
few required libraries are not deployed during the default RHEL6
operating system installation. Because of this, users need to port the
application in to the native 64-bit version.
Refer to your server documentation and to the operating system documentation for more information on hardware
requirements and operating system requirements.
6.3

Creating a New Storage Configuration
Chapter 7: Configuration
This chapter explains how to use MegaRAID Storage Manager to create and modify storage configurations on LSI
RAID controllers.
The LSI RAID controllers support RAID 0, RAID 1, RAID 5, and RAID 10 storage configurations. The Configuration
Wizard allows you to create new storage configurations and modify the configurations. To learn more about RAID and
RAID levels, see Section 1.2, RAID Overview, on page 9.
NOTE
7.1
You cannot create or modify a storage configuration unless you are
logged on to a server with administrator privileges.
Creating a New Storage Configuration
You can use the MegaRAID Storage Manager to create new storage configurations on systems with LSI RAID
controllers. You can create the following types of configurations:


Simple configuration specifies a limited number of settings and has the system select drives for you. This option
is the easiest way to create a virtual drive.
Advanced configuration lets you choose additional settings and customize virtual drive creation. This option
provides greater flexibility when creating virtual drives for your specific requirements.
This section describes the virtual drive parameters and explains how to create simple storage configurations and
advanced storage configurations.
7.1.1
Selecting Virtual Drive Settings
This section describes the virtual drive settings that you can select when you use the advanced configuration
procedure to create virtual drives. Change these parameters only if you have a specific reason for doing so. It is usually
best to leave them at their default settings.

Initialization State – Initialization prepares the storage medium for use. Specify the initialization status:
— No Initialization: (the default) The new configuration is not initialized and the existing data on the drives is
not overwritten.
— Fast Initialization: This option allows you to start writing data to the virtual drive immediately.
— Full Initialization: A complete initialization is done on the new configuration. You cannot write data to the
new virtual drive until the initialization is complete. This can take a long time if the drives are large.
NOTE


New RAID 5 virtual drives require at least five drives for a background
initialization to start.
Stripe size – The setting is 64 KB only.
Read policy – Specify the read policy for this virtual drive:
— No read ahead: (the default) Disables the read ahead capability. Read ahead capability allows the controller to
read sequentially ahead of requested data and to store the additional data in cache memory, anticipating
that the data will be needed soon. Read ahead capability speeds up reads for sequential data, but there is
little improvement when accessing random data.

Embedded MegaRAID Software User Guide



Creating a New Storage Configuration
Write policy – Specify the write policy for this virtual drive:
— Write Through: In this mode, the controller sends a data transfer completion signal to the host when the drive
subsystem has received all the data in a transaction. This option eliminates the risk of losing cached data in
case of power failure.
— Always Write Back: In this mode, the controller sends a data transfer completion signal to the host when the
disk cache has received all the data in a transaction.
I/O policy – The I/O policy applies to reads on a specific virtual drive. It does not affect the read ahead cache.
— Direct IO: (the default) In this mode, reads are not buffered in cache memory. Data is transferred to the cache
and the host concurrently. If the same data block is read again, it comes from cache memory.
Cached IO provides faster processing, and Direct IO ensures that the cache and the host contain the
same data.


7.1.2
Access policy – Select the type of data access that is allowed for this virtual drive.
— Read/Write: (the default) Allow read/write access. This setting is the default.
— Read Only: Allow read-only access.
— Blocked: Do not allow access.
Disk cache policy – Select a cache setting for this drive:
— Enabled: Enable the disk cache.
— Disabled: Disable the disk cache.
— Unchanged: (the default) Leave the current disk cache policy unchanged.
Creating a Virtual Drive Using Simple Configuration
Simple configuration is the quickest and easiest way to create a new storage configuration. When you select simple
configuration mode, the system creates the best configuration possible using the available drives.
NOTE
You cannot created RAID 10 spanned drives using the simple
configuration procedure. To create RAID 10 spanned drives, use the
advanced configuration procedure described in Section 7.1.3,
Creating a Virtual Drive Using Advanced Configuration, on page 94.
Follow these steps to create a new storage configuration in simple configuration mode.

Running a Patrol Read
Running a Patrol Read
A patrol read periodically verifies all sectors of drives connected to a controller, including the system reserved area in
the RAID configured drives. A patrol read can be used for all RAID levels and for all hot spare drives. This operation is
initiated only when the controller is idle for a defined time period and has no other background activities.
You can set the patrol read properties and start the patrol read operation, or you can start the patrol read without
changing the properties.
To set the patrol read properties and then start a patrol read, follow these steps:
1.
Click a controller icon in the left panel of the MegaRAID Storage Manager main menu screen.

Initializing a Virtual Drive
Chapter 9: Maintaining and Managing Storage Configurations
This chapter explains how to use Embedded RAID to maintain and manage storage configurations.
9.1
Initializing a Virtual Drive
To initialize a virtual drive after completing the configuration process, follow these steps:
1.
Select the Logical tab in the left panel of the MegaRAID Storage Manager main menu screen, and click the icon of
the virtual drive that you want to initialize.
2.
Select Go To > Virtual Drive > Start Initialization.
The initialize dialog box appears.
3.
Select the virtual drive(s) to initialize.
CAUTION
4.
Initialization erases all data on the virtual drive. Make sure to back
up any data you want to keep before you initialize. Make sure the
operating system is not installed on the virtual drive you
are initializing.
Select the Fast Initialization check box if you want to use this option.
If you leave the box unchecked, MegaRAID Storage Manager runs a Full Initialization on the virtual drive. For more
information, see Section 9.1.1, Running a Group Initialization, on page 120.
5.
Click Start to begin the initialization.
You can monitor the progress of the initialization. For more information, see Section 8.8, Monitoring Rebuilds and
Other Processes, on page 118.
9.1.1
Running a Group Initialization
Initialization prepares the storage medium for use. You can run an initialization on multiple drives at one time. Follow
these steps to run a group initialization.
1.
Click Manage > Initialize.

3.
Click Start.
You can monitor the progress of the group initialization. See Section 8.8, Monitoring Rebuilds and Other
Processes, on page 118, for more information.
9.2
Running a Consistency Check
The Consistency Check operation verifies correctness of the data in virtual drives that use RAID levels 1, 5, and 10.
(RAID 0 does not provide data redundancy). For example, in a system with parity, checking consistency means
computing the data on one drive and comparing the results to the contents of the parity drive.
You should run a consistency check on fault-tolerant virtual drives periodically. You must run the consistency check if
you suspect that the virtual drive data might be corrupted. Be sure to back up the data before running a consistency
check if you think the data might be corrupted.
To run a consistency check, first set the consistency check properties and then schedule the consistency check. This
section explains how to set the properties, schedule the check, and run the consistency check.

Scanning for New Drives
Scanning for New Drives
You can use the Scan for Foreign Configuration option to find drives with foreign configurations. A foreign
configuration is a RAID configuration that already exists on a replacement set of physical disks that you install in a
computer system. In addition, if one or more drives are removed from a configuration, by a cable pull or drive removal,
for example, the configuration on those drives is considered a foreign configuration by the RAID controller. Drives that
are foreign are listed on the physical drives list with a special symbol in MegaRAID Storage Manager.
The utility allows you to import the existing configuration to the RAID controller or clear the configuration so you can
create a new configuration using these drives. You can preview the foreign configuration before you decide whether to
import it.
MegaRAID Storage Manager normally detects newly installed drives and displays icons for them in the MegaRAID
Storage Manager main menu screen. If for some reason MegaRAID Storage Manager does not detect a new drive (or
drives), you can use the Scan for Foreign Configuration command to find it.
Follow these steps to scan for a foreign configuration:
1.
Select a controller icon in the left panel of the MegaRAID Storage Manager main menu screen.
2.
Select Go To > Controller > Scan for Foreign Configuration.
If MegaRAID Storage Manager detects any new drives, it displays a list of them on the screen. If not, it notifies you
that no foreign configuration is found.
3.
9.4
Follow the instructions on the screen to complete the drive detection.
Rebuilding a Drive
If a single drive in a RAID 1, RAID 5, or RAID 10 virtual drive fails, the system is protected from data loss. If hot spare
disks are available, a failed drive is rebuilt automatically without any user intervention. A failed drive must be replaced,
and the data on the drive must be rebuilt on a new drive to restore the system to fault tolerance. (You can choose to
rebuild the data on the failed drive if the drive is still operational.) If hot spare drives are available, the failed drive is
rebuilt automatically without any user intervention.
If a drive has failed, a red circle appears to the right of the drive icon:
. A small yellow circle appears to the right
of the icon of the virtual drive that uses this drive:
. This indicates that the virtual drive is in a degraded state; the
data is still safe, but data could be lost if another drive fails.
Follow these steps if you need to rebuild a drive:
1.
Right-click the icon of the failed drive, and select Rebuild.
2.
Click Yes when the warning message appears.
If the drive is still good, a rebuild starts. You can monitor the progress of the rebuild in the Group Show Progress
window by selecting Manage > Show Progress.
If the drive cannot be rebuilt, an error message appears. Continue with the next step.
3.
Shut down the system, disconnect the power cord, and open the computer case.
4.
Replace the failed drive with a new drive of equal capacity.
5.
Close the computer case, reconnect the power cord, and restart the computer.
6.
Restart MegaRAID Storage Manager.
When the new drive spins up, the drive icon changes back to normal status, and the rebuild process begins
automatically. You can monitor the progress of the rebuild in the Group Show Progress window by selecting
Manage > Show Progress.

Making a Drive Offline or Missing
Making a Drive Offline or Missing
If a drive is currently part of a redundant configuration and you want to use it in another configuration, you can use
MegaRAID Storage Manager commands to remove the drive from the first configuration and change the drive state to
Unconfigured Good.
CAUTION
After you perform this procedure, all data on that drive is lost.
To remove the drive from the configuration without harming the data on the virtual drive, follow these steps:
1.
In the MegaRAID Storage Manager main menu, click Go To > Physical Drive > Make Drive (O)ffline.
The drive status changes to Offline.
2.
Click Go To > Physical Drive > (M)ark Drive as Missing.
The drive status changes to Unconfigured Good.
CAUTION
3.
After you perform this step, the data on this drive is no longer valid.
If necessary, create a hot spare drive for the virtual drive from which you have removed the drive.
When a hot spare is available, the data on the virtual drive is then rebuilt. You can now use the removed drive for
another configuration.
CAUTION
If MegaRAID Storage Manager detects that a drive in a virtual drive has
failed, it makes the drive offline. If this happens, you must remove the
drive and replace it. You can make the drive so that another
configuration cannot use it by using the Mark physical disk as
missing command and the Rescan command.
