1After all of the drives are connected to the ATA RAID Controller and it is installed in its slot, verify that the cables do not interfere with the operation of any other components in the case or block the flow of cooling air.
2Close the case and reconnect the power cables.
Check motherboard boot sequence
Using your computer???s Setup utility, ensure that your boot device precedes the Escalade ATA RAID Controller in the boot sequence. If you have other disks installed on the motherboard, theATA RAID Controller precedes them in boot order.
3ware Disk Array Configuration Utility
3ware Disk Array Configuration Utility
The 3ware Disk Array Configuration Utility allows you to create disk arrays by combining disks, deleting disks or breaking disk arrays back into their member disks. You can also specify an avail- able drive as a hot spare. If an array becomes degraded, the hot spare will automatically be substituted for the faulted drive.
Note: The BIOS will not be installed if no drives are attached to the Escalade ATA RAID Controller. The ATA RAID Controller shares one IRQ on the PCI bus.
Hot spare and hot swap
Hot Spare is the label given to a drive that is available, active and designated as a spare. This designated drive is applied automati- cally when a drive degrades and the array is rebuilt. Hot Swap is the term applied to the process of swapping out a degraded drive, pro- grammatically and using 3DM, with a
There are two methods for adding a drive as a spare. You may des- ignate a drive as a Hot Spare during the BIOS page display, or you may designate a drive as a Hot Spare through the 3DM configure page. These two methods are discussed below.
BIOS Screen
When designating spare in the BIOS screen, it is assumed that as you are creating your array, you are ???setting aside??? drive(s) as Hot Spares. This is done by using the S key on the selected drive. Leav- ing a drive undesignated results in it becoming a JBOD drive. JBOD drives become available to the operating system as distinct
3ware Escalade ATA RAID Controller Installation Guide
volumes, and, consequently, they cannot be designated as spares at a later time. If a spare is designated in the BIOS screen, the designa- tion and configuration is in effect from this point on. The spare drive will be displayed as a Hot Spare in the 3DM configuration page.
3DM Configure Page
In order to designate an available drive as a spare from the 3DM configure page, you must ensure that the drive is not a JBOD drive or part of an existing array. To designate a drive as a Hot Spare from this page, you must use one of the two following methods:
Replacing a Defective Drive with a Spare
Replace the drive at the operating system level while the system is powered. This should only be done with an approved and recog- nized hot swap
Adding a Spare Drive to an Available Port
To add a new spare, follow the same steps except you will not be required to remove a drive.
Invoking the 3ware BIOS tool
Power up or reboot your system. Before the boot phase, wait until you see a screen similar to Figure 4.

Figure 7. Selecting Drives for a Mirrored Array
3ware Escalade ATA RAID Controller Installation Guide
Determining your configuration
Hint: The capacity of each drive is limited to the capacity of the smallest drive in the array. The total array capacity is defined as follows:
RAID 0: (the number of drives) X (the capacity of the smallest drive)
RAID 1: the capacity of the smallest drive
RAID 5: (the number of drives - 1) X (capacity of the smallest drive)
RAID10: (the number of drives / 2) X (capacity of smallest drive)
Navigate to the Create Array button after selecting all the drives for the array. Hit Enter to bring up the Create Disk Array display (see Figure 8 and Figure 9 for examples). Check that the proper drives are listed.

Select RAID configuration
The Escalade ATA RAID Controller gives you a choice of four RAID configurations. Select one.
???Stripe (RAID 0): maximizes performance and capacity through a process called striping. High performance arrays write portions of a single file across multiple drives. There is no fault tolerance.
???Mirror (RAID 1): duplicates or ???mirrors??? the data on both drives. No data will be lost if one of the drives fails.
???RAID 10: combines mirroring and striping, providing both fault tolerance and high performance. RAID 10 arrays require a minimum of four drives. Configurations consist of 4, 6, 8, 10 or 12 drives.
???RAID 5: combines parity data and striping, providing fault toler- ance, high capacity and high storage efficiency. The parity data is distributed across all drives, rather than being concentrated on
3ware Escalade ATA RAID Controller Installation Guide
a single disk. RAID 5 arrays require a minimum of three
drives. Configurations consist of at least 3 drives and up to 12 drives.
3ware Disk Array Configuration
Figure 10. BIOS Initialization Screen for RAID 5
Select striping size
For a RAID 0 or RAID 10 configuration select the striping size. Sizes of 64K, 128K, 256K, 512K or 1M are selected using the Stripe Size box shown in Figure 8. RAID 5 only allows a 64K stripe size. RAID 1 does not allow the user to select the striping size.
Select write cache properties
The Escalade ATA RAID Controller gives you a choice of disabling the write cache for your disk arrays. Write cache is used to store data locally on the drive before it is written to the disk, allowing the computer to continue with its next task. Enabling the write cache
3ware Disk Array Configuration Utility
results in the most efficient access times for your computer system. There may be instances when you always want the computer to wait for the drive to write all the data to disk before going on to its next task. For this case, you must disable the write cache. To disable the write cache, select disable from the array???s Write Cache State selection. The default for Write Cache State is enable.
Confirm array configuration
Select the OK button to confirm creating the array or Cancel to reject it. The array is not actually created and no data will be over- written until you have finished making all your changes and select the F8 key.
Note: The current limitation is 2 TB for any physical or logical unit. If you attempt to create an array over 2 TB the BIOS will display the following message: ???The amount of disk space available exceeds the maxi- mum allowable capacity. The array capacity will be lim- ited to 2 TB.???
For RAID 5 Arrays
Because of the

3ware Escalade ATA RAID Controller Installation Guide
the array to be fully redundant, as it takes longer to initialize an array than it takes to write zeros to the array.
Caution: When running in initializing mode the array is not redundant. You cannot remove any drive.
For RAID 1 or 10 Arrays
RAID 1 and 10 arrays are not profiled when created, or initialized after booting into the OS. When the firmware receives the first ver- ify request, given that the array was never initialized, the initializa- tion will then begin. Any subsequent verify operations will then perform the verification of the array (check data consistency). An AEN will inform the user that the first verify is actually an initial- ization.
Specifying a Hot Spare
The Escalade ATA RAID Controller gives you the option to specify a hot spare from one of your Available Drives. If a hot spare is specified and the array degrades, an event notification will be gen- erated. The hot spare will dynamically replace the failed drive in an array without user intervention. Select a hot spare by navigating to an Available Drive. The Toggle Hot Spare verbiage at the bottom of the screen will be black if the drive can be used as a hot spare. Enter s to select the hot spare or to disable the hot spare if it is already enabled.
3ware Disk Array Configuration Utility
Note: Hot spare drives need to have the same or larger storage capacity than the RAID 1, RAID 5 or RAID 10 drives.
Changing an existing configuration
1Back up any disk arrays that contain data that you want to retain before the configuration change.
2Create new disk arrays following the instructions in the Deter- mining your configuration, Creating a disk array and Delet- ing a disk array sections. You may need to delete existing arrays to free up disks first.
3Boot, partition and format any new disk arrays or free disks.
4When you are finished configuring, restore from backup any data saved from previous disk arrays
Modifying a disk array
To modify an existing array you must first delete it then recreate it with the new drives. As with all disk array operations, there is no way to modify an existing array without overwriting data on the drives involved.
Deleting a disk array
To delete an array (see Figure 11) first select the array by navigat- ing to it and hitting Enter. An asterisk in the left most column indi- cates the array is selected.

Figure 11. Delete Disk Array Display
Navigate to the Delete Array button and hit Enter to bring up the Delete Disk Array display. Check that the correct drives are listed. Select the OK key to confirm deleting the array or Cancel to reject it. Recall that the array is not actually deleted and no data will be overwritten until you have finished making all your changes and selected the F8 key.
How to maintain or verify a disk array
The Maintain Disk Array (see Figure 12) shows the current disk array configuration that you have selected. The array???s Write Cache State can be changed. Refer to Select write cache proper- ties paragraph in the Creating a disk array section. Verify Array can be specified as no or yes. The default is no. Yes launches a fore- ground process that checks the data integrity of a fault tolerant
3ware Disk Array Configuration Utility
array. If the verify array process determines that the mirrored drives are not identical or the parity is not correct, the array is degraded and the rebuild process is launched.
Maintain Disk Array
The array listed below can have its write cache state changed. Verify checks the data integrity of a fault tolerant array.
Figure 12. Maintain Disk Array Display
Note: Fault tolerant arrays can not be verified until after they are initialized. For RAID 1 and 10 arrays the initial verify must first be done in 3DM, otherwise the initialization will not be done.
Rebuilding a mirrored disk array
Escalade ATA RAID Controllers allow you to create fault tolerant disk arrays by selecting a mirrored RAID 1 or RAID 10 array. These disk arrays store identical data on two or more drives to pro- tect against drive failure. If one or more of the drives of a mirrored
3ware Escalade ATA RAID Controller Installation Guide
array is removed, unplugged or fails on read or write requests, the array is marked as DEGRADED and the drive is marked as Not In Use or is not displayed if no longer available. (see Figure 13 and Figure 14).
You can still read and write data from a degraded disk array, but the array will not be fault tolerant until it is rebuilt using the Rebuild feature, described in the 3ware Disk Array Configuration Utility or 3DM Disk Management Utility chapters.

Escalade ATA RAID Controllers allow you to create fault tolerant RAID 5 disk arrays. These disk arrays achieve fault tolerance by using a simple (exclusive OR) function to generate the parity data

that is distributed on all drives. If one of the drives is removed, unplugged or fails on read or write requests, the array is marked as DEGRADED and the drive is marked as Not In Use or is not dis- played if no longer available (see Figure 15). When running in Degraded mode, the missing data is reconstructed from all non- degraded drives.
Figure 15. Degraded RAID 5 Array Drive When Not in Use
As in the case of RAID 1 and 10 arrays RAID 5 arrays allow you to read and write data from a degraded disk array, but the array will not be fault tolerant until it is rebuilt using the Rebuild feature. (Refer to the 3ware Disk Array Configuration Utility or 3DM Disk Management Utility chapters for more information.)
Rebuilding a mirrored or RAID 5 array with no hot spare
1Reboot the system and enter the Disk Array Configuration Utility.
3ware Disk Array Configuration Utility
2If your mirrored or RAID 5 array has a Not in Use member drive, the drive may still be usable. Try rebuilding with the Not in Use drive intact. Simply select the array and then the Rebuild button.
3Confirm that you selected the correct array by hitting OK in the Rebuild confirmation display.
4Select F8 to exit the Disk Array Configuration Utility. The array will begin rebuilding after completion of the operating sys- tem load.
5If the rebuild fails and you have no Available Drives, you must power down the system and replace the failed or Not In Use drive. Power on the system and enter the Disk Array Configu- ration Utility.
6Select an available drive to replace the faulted drive in the array by navigating the cursor over the available drive and hitting Enter (see Figure 16). An asterisk in the left most column indi- cates the drive is selected.
7Navigate to the degraded array and press Enter to select it.

8Navigate to the Rebuild Array button and press Enter (see Figure 17). A status screen will be displayed with your requested array and member drives.
9Select OK to continue.

Creating or destroying arrays will destroy all existing data on their member disk drives. Using a drive for a rebuild will overwrite data on that drive.
Data on the following drives will be destroyed.

Auto rebuild of a mirrored or RAID 5 array
If a hot spare is specified and the mirrored or RAID 5 array degrades, an event notification is generated and the hot spare dynamically replaces the failed drive in the array without user inter- vention. Rebuild will automatically be launched as a background process and an event notification will notify the user when the rebuild process is complete.
3ware Disk Array Configuration Utility
Auto rebuild on power failure
During driver startup 3ware???s auto rebuild feature sets a flag indi- cating that the driver loaded. Upon an orderly shutdown the flag is rewritten, indicating a clean shutdown. During the next system power cycle the firmware queries the flag. For a RAID 1 or 10 con- figuration, if there was a problem, the firmware degrades the sec- ondary drive in the array and starts the background rebuild of the mirrored drive. When the rebuild is complete the two halves of the mirror are redundant again. For a RAID 5 configuration, if there is a problem, the firmware starts the background verification that checks that the parity matches the data.
Cancelling and restarting a rebuild with a new drive
Currently, a rebuild cannot be cancelled using the 3DM software, but a rebuild can be aborted by physically removing the disk used to replace the degraded drive. Abort a rebuild by following the appli- cable procedure below.
If your system has hot swap carriers:
1Remove the disk while the system is powered. The rebuild will be immediately aborted.
2Go to the Configure screen and click the box in front of the disk drive that was removed. Click on Remove Drive.
3Add another drive and click on the box in front of this port. Click on Add Drive. The drive is called ???RAID Disk???.
4Click the boxes in front of the RAID Disk and the degraded array. Select Rebuild. The rebuild starts with the new disk drive.
If your system does not have hot swap carriers:
1Power down the system and remove the disk drive that caused the array to become degraded.
2Add a different disk drive to rebuild the array.
3Press Alt + F3 at Boot time to enter 3ware BIOS.
4Select the degraded array and the newly added drive.
5Select Rebuild.
3ware Escalade ATA RAID Controller Installation Guide
6 Press F8 to start a rebuild with this drive.
Note: If the rebuild is not started in the 3ware BIOS, the new drive cannot be used to rebuild the degraded array. Booting with the drive attached will make the drive appear as a single disk (JBOD) to the operating system.

Hardware installation
Q1: The rail on the ATA RAID controller doesn't fit in the case.
Use a screwdriver to remove the black end rail. It aligns and secures the ATA RAID controller in the computer chassis but is not critical for operation.
Q2: The system doesn???t begin booting (no BIOS runs) when the ATA RAID controller is installed but boots OK when the con- troller is removed.
Check the cabling between the drives and the ATA RAID controller. A cable plugged in upside down can prevent your system from run- ning its BIOS.
3ware Escalade ATA RAID Controller Installation Guide
Q3: The 3ware BIOS screen never appears.
The ATA RAID controller is not installed properly. Reinstall the hardware and reboot. There may also be a problem with the mother- board. Please check the Motherboard Compatibility List on the 3ware website at http://www.3ware.com/products/compatibility.asp to see if you motherboard has been tested by 3ware.
Q4: Some of the drives do not appear in the Disk Array Config- uration Utility???s main display.
Your drives are not connected properly to the ATA RAID controller. Check that both the power and ATA cables are connected properly and that the drives are all properly jumpered. To operate properly the ATA RAID controller requires that drives be set as Single (if available on your drive) or Master.
