							B-15 Intel ICH7R SATA RAIDRAID Migration InstructionsImportant
A Create from Existing Disk operation will delete all existing data from the
added disk and the data cannot be recovered. It is critical to backup all
important data on the added disk before proceeding. However, during the
migration process, the data on the source disk is preserved. The Intel Matrix Storage Console offers the flexibility to upgrade from a single Serial
ATA (SATA) hard drive to RAID configuration when an additional SATA hard drive is
added to the system. This process will create a new RAID volume from an existing
disk. However, several important steps must be followed at the time the system is
first configured in order to take advantage of RAID when upgrading to a second
SATA hard drive:
1.BIOS must be configured for RAID before installing Windows XP on the
single SATA hard drive. Refer to On Chip SATA Setting for properly
setting of the BIOS.
2.Install the Intel Application Accelerator RAID Driver during Windows Setup.
Refer to Installing Software for instructions on installing the driver dur-
ing Windows Setup.
3.Install the Intel Matrix Storage Console after the operating system is installed.
To create a volume from an existing disk, complete the following steps:
After the Intel Matrix Storage Console has been successfully installed and the sys-
tem has rebooted, click on the Intel Application Accelerator shortcut link (Start --> All
Programs --> Intel Matrix Storage Manager --> Intel Matrix Storage Console)
and the following window will appear:7528v1.0-B_ICH7R RAID.p65  2008/2/1, 下午 04:3115

B-16Create RAID Volume from Existing Disk
To create a RAID volume from an existing disk, choose Action --> Create RAID
Volume from Existing Hard Drive.The Create RAID Volume from Existing Hard Drive Wizard pops up to lead you
for the following procedure. Click Next to continue.7528v1.0-B_ICH7R RAID.p65  2008/2/1, 下午 04:3116 
						

							B-17 Intel ICH7R SATA RAID
(1) Step 1: Configure Volume
Here you can configure the new RAID volume by entering the volume name, selecting
the RAID level and strip size.† RAID Volume Name:
A desired RAID volume name needs to be typed in where the ‘RAID_Volume1’ text
currently appears above. The RAID volume name has a maximum limit of 16 characters.
The RAID volume name must also be in English alphanumeric ASCII characters.
† RAID Level:
Select the desired RAID level:
RAID 0 (Performance) –A volume optimized for performance will allow you to
access your data more quickly.
RAID 1 (Redundancy) –A volume optimized for data redundancy will provide
you with a realtime duplicate copy of your data. Note:
Only half of the available volume space will be avail-
able for data storage.
RAID 5 (Useful) –RAID 5 can be used on three or more disks, with zero
or more spare-disks. The resulting RAID-5 device size
will be (N-1)*S, where N is the how many drive, S is the
size of the smallest drive in the array. If one of the disks
fail, all data are still intact. It can rebuild the disk from
the parity information. If spare disks are available, re-
construction will begin immediately after the device
failure. If two disks fail simultaneously, all data are lost.
RAID-5 can survive one disk failure, but not two or
more. Both read and write performance usually
increase, but can be hard to predict how much. Reads
are similar to RAID-0 reads, writes can be either rather7528v1.0-B_ICH7R RAID.p65  2008/2/1, 下午 04:3117

B-18expensive (requiring read-in prior to write, in order to
be able to calculate the correct parity information), or
similar to RAID-1 writes. The write efficiency depends
heavily on the amount of memory in the machine, and
the usage pattern of the array. Heavily scattered writes
are bound to be more expensive.
RAID 10 (Mirrored Stripes) –A RAID 1 array of two RAID 0 arrays.
† Strip Sizes:
Select the desired strip size setting. As indicated, the optimal setting is 128KB. Se-
lecting any other option may result in performance degradation. Even though 128KB
is the recommended setting for most users, you should choose the strip size value
which is best suited to your specific RAID usage model. The most typical strip size
settings are:
4KB: For specialized usage models requiring 4KB strips
8KB: For specialized usage models requiring 8KB strips
16KB: Best for sequential transfers
32KB: Good for sequential transfers
64KB: Good general purpose strip size
128KB: Best performance for most desktops and workstations
(2) Select the source disk
Then select the source disk that you wish to use and then click “--->” to move it to the
Selected field. Then click Next to continue.
It is very important to note which disk is the source disk (the one containing all of the
information to be migrated) and which one is the target disk. On a RAID Ready
system, this can be determined by making a note during POST of which port (e.g. Port
0 or Port 1) the single disk is attached to.
You can also use the Intel Application Accelerator RAID Edition utility before the
second disk is installed to verify the Port and serial number of the drive that contains
all the data.7528v1.0-B_ICH7R RAID.p65  2008/2/1, 下午 04:3118

(3) Select Member Hard Drive(s)
Then select the member disk (the target disk) that you wish to use and then click “-
-->” to move it to the Selected field. Then click Next to continue.
Please note that the existing data on the selected hard drive(s) will be deleted
permanently. Do not forget to back up all the important data before continuing.7528v1.0-B_ICH7R RAID.p65  2008/2/1, 下午 04:3119 
						

							MS-7528 Mainboard
B-20(4) Specify Volume Size
Specify the amount of available array space to be used by the new RAID volume. You
may enter the amount in the space or use the slider to specify. It is recommended you
use 100% of the available space for the optimized usage. For RAID 0 volume, if you
do not specify 100% of the hard drive space, the rest hard drive space will be
worked as RAID 1 volume, which is the new technology called Intel Matrix RAID. Then
click Next to continue.(5) Start Creating RAID Volume from Existing Hard Drive Wizard
Before you continue the procedure of RAID volume creation from existing hard drive,
read the dialogue box below carefully. Please note that once you click Finish, the
existing data on the selected hard drive(s) will be deleted permanently and this
operation cannot be undone. It is critical that you backup all important data before
selecting Finish to start the migration process.7528v1.0-B_ICH7R RAID.p65  2008/2/1, 下午 04:3120 
						

							B-21 Intel ICH7R SATA RAID
(6) Start Migration
The migration process may take up to two hours to complete depending on the size
of the disks being used and the strip size selected. A dialogue window will appear
stating that the migration process may take considerable time to complete, meanwhile
a popup dialogue at the taskbar will also show the migration status. While you can still
continue using your computer during the migration process, once the migration proc-
ess starts, it cannot be stopped. If the migration process gets interrupted and your
system is rebooted for any reason, it will pick up the migration process where it left
off. You will be provided with an estimated completion time (the remaining time will
depend on your system) once the migration process starts.
The following screen appears if the migration process is completed successfully.
Then you have to reboot your system to use the full capacity of the new volume.7528v1.0-B_ICH7R RAID.p65  2008/2/1, 下午 04:3121

B-22A RAID 1, RAID 5 or RAID 10 volume is reported as degraded when one of its hard
drive members fails or is temporarily disconnected, and data mirroring is lost. As a
result, the system can only utilize theremaining functional hard drive member. To re-
establish data mirroring and restore data redundancy, refer to the procedure below
that corresponds to the current situation.
Missing Hard Drive Member
1. Make sure the system is powered off.
2. Reconnect the hard drive.
3. Reboot the system to Windows; the rebuild will occur automatically.
Failed Hard Drive Member
1. Make sure the system is powered off.
2. Replace the failed hard drive with a new one that is of equal or greater
capacity.
3. Reboot the system to Intel RAID Option ROM by press  and  keys
simultaneously during the Power-On Self Test (POST).Degraded RAID Array
4. Select the port of the destination disk for rebuilding, and then press ENTER.7528v1.0-B_ICH7R RAID.p65  2008/2/1, 下午 04:3122
