events.
Information Notication: Send all events. Notication For No Event: Notify user if no event occurs within 24
hours.
SNMP Traps Conguration: To enable the RAID controller to send the SNMP traps to client SNMP manager using the IP address assigned to the operating system, such as Net-SNMP manager, you can simply use the SNMP
function on the ArcHttp proxy server software. To enable the RAID controller SNMP traps sending function, click on the “SNMP Conguration” link. The Archttp proxy only provide one direction
to send the trap to the SNMP manager without needing to install
the SNMP extension agent on the host. If SNMP manager requests
to query the SNMP information from RAID controller, please refer
the Appendix C "SNMP Operation & Installation". The “SNMP traps Conguration” menu will be shown as following:
113
ARCHTTP PROXY SERVER INSTALLATION
When you open the SNMP traps conguration page, you will see the
following settings:
(1). SNMP Trap Congurations
Enter the SNMP trap IP address.
(2). SNMP System Congurations
Community name acts as a password to screen accesses to the SNMP agent of a particular network device. Type the community
names of the SNMP agent in this eld. Before access is granted to
a request station, this station must incorporate a valid community name into its request; otherwise, the SNMP agent will deny access
to the system. Most network devices use “public” as default of their
community names. This value is case-sensitive.
(3). SNMP Trap Notication Congurations
Before the client side SNMP manager application accepts the 6Gb/ s SATA RAID controller traps, it is necessary to integrate the MIB into the management application’s database of events and status indicator codes. This process is known as compiling the MIB into
the application. This process is highly vendor-specic and should be
well-covered in the User’s Guide of your SNMP application. Ensure the compilation process successfully integrates the contents of the
areca_SATA.mib le into the traps database. Please refer to Appen-
dix C of “SNMP Operation & Installation”. The MIBs le resides at:
<CD-ROM>\packages\SNMP_MIBs on the software CD.
Note:
Event Notication Table refer to Appendix D. After you conrm and submit congurations, you can use "Generate Test Event" feature to make sure these settings are
correct.
• Rescan Device Conguration:
Let's assume you've put all Areca RAID adapters to a system. The Archttp scans the RAID adapters on the system and create an individual adapter icon located on left column of the Archttp
Congurations screen. This adapter icon is for user to launch web
browser RAID manager. If there is any RAID adapter missed on the
system start-up, you can use the "Rescan Device" function. The
114
"Rescan Device" function is a procedure which forces the archttp to
rescan the targets to allow a missed RAID adapter to be added.
Collect Support Data:
Areca has added the “Collect Support Data” option on the Archttp proxy server utility to download a support le (le name:ctlrxx­xxxxx.log) with all necessary information (system information, conguration, disk information, eventlog). The “Collect Support Data” function will be automatically started when ERROR or
SERIOUS event has occurred.

6. Web Browser-based Conguration
Before using the rmware-based browser McRAID storage manager, do the initial setup and installation of this product. If you need to boot up
the operating system from a RAID volume set, you must rst create a
RAID volume by using McBIOS RAID manager. Please refer to section
3.3 “Using Quick Volume /Raid Setup” conguration for information on
creating this initial volume set.
The McRAID storage manager is rmware-based utility, which is acces­sible via the web browser installed on your operating system. The web browser-based McRAID storage manager is a HTML-based application, which utilizes the browser (IE, Safari, Netscape and Mozilla etc) in­stalled on your monitor station.
It can be accessed through the in-band PCIe 2.0 bus or out-of-band LAN port. The in-band method can launch the web browser-based
McRAID storage manager via archttp proxy server. The rmware-
embedded web browser-based McRAID storage manager allows local or remote to access it from any standard internet browser via a LAN
or WAN with no software or patches required. The rmware contains
SMTP manager monitors all system events and user can select either
single or multiple user notications to be sent via LAN with “Plain Eng­lish” e-mails. The rmware-embedded SNMP agent allows remote to
monitor events via LAN with no SNMP agent required.

128 volumes is the default mode for SAS RAID controller, the 16
volumes mode is used for support roaming this raidset to 3Gb/s SATA RAID controllers. The 3Gb/s SATA RAID controller is de-
signed to support up to 16 volumes only. You have to use “Max 16 volumes” on the raidset mode if you plan to roam this raidset
between 6Gb/s SATA RAID controller and 3Gb/s SATA RAID con­troller.
Note:
To create RAID 30/50/60 volume, you need create multiple
RAID sets rst (up to 8 RAID sets) with the same disk numbers on each RAID set. The max no. disk drives per RAID set: 24 for RAID 0/10(1E)/3/5/6/30/50/60.
6.5.2 Delete Raid Set
To delete a RAID set, click on the “Deleted Raid Set” link. A “Select The RAID Set To Delete” screen is displayed showing all exist RAID sets in the current controller. Click the RAID set num-
ber which you want to delete in the select column on the delete
screen. Then, click the “Conrm The Operation” check box and click on the “Submit” button in the screen to delete it. The volume sets included in the “Delete RAID Set”. It will be deleted by this
action. But for the Raid 30/50/60, you need to delete the volumes belonging to those RAID sets.
6.5.3 Expand Raid Set
Instead of deleting a RAID set and recreating it with additional
disk drives, the “Expand Raid Set” function allows the users to
add disk drives to the RAID set that have already been created.
To expand a RAID set:
122
WEB BROWSER-BASED CONFIGURATION
Select the “Expand Raid Set” option. If there is an available disk, then the “Select SATA Drives For Raid Set Expansion” screen
appears.
Select the target RAID set by clicking on the appropriate radio button. Select the target disk by clicking on the appropriate check

RAID set. The new additional capacity can be utilized by one or more volume sets. The volume sets associated with this RAID set appear for you to have chance to modify RAID level or stripe size.
Follow the instruction presented in the “Modify Volume Set ” to modify the volume sets; operation system specic utilities may be required to expand operating system partitions.
Note:
1. Once the “Expand Raid Set” process has started, user can
not stop it. The process must be completed.
2. If a disk drive fails during RAID set expansion and a hot
spare is available, an auto rebuild operation will occur after
the RAID set expansion completes.
3. RAID 30/50/60 does not support the "Expand Raid set".
4. RAID set expansion is a quite critical process, we strongly recommend customer backup data before expand. Unex-
pected accident may cause serious data corruption.
6.5.4 Ofine Raid Set
This function is for customer being able to unmount and remount a multi-disk volume. All Hdds of the selected RAID set will be put
into ofine state, spun down and fault LED in fast blinking mode.
User can remove those Hdds and insert new Hdds on those empty slots without needing power down the controller.

6.5.9 Rescue Raid Set
When the system is powered off in the RAID set update/creation
period, the conguration possibly could disappear due to this ab­normal condition. The “RESCUE” function can recover the missing
RAID set information. The RAID controller uses the time as the RAID set signature. The RAID set may have different time after
the RAID set is recovered. The “SIGANT” function can regenerate
the signature for the RAID set.
Caution:
Please contact us to make sure if you need to use rescue
function. Improperly usage may cause conguration
corruption.

WEB BROWSER-BASED CONFIGURATION
6.6 Volume Set Functions
A volume set is seen by the host system as a single logical device. It is organized in a RAID level with one or more physical disks. RAID level refers to the level of data performance and protection of a volume set. A volume set capacity can consume all or a portion of the disk capacity available in a RAID set. Multiple volume sets
can exist on a group of disks in a RAID set. Additional volume sets created in a specied RAID set will reside on all the physical disks
in the RAID set. Thus each volume set on the RAID set will have its data spread evenly across all the disks in the RAID set.
The following summaries are the volume set features for the 6Gb/s SATA RAID controller.
1. Volume sets of different RAID levels may coexist on the same RAID set and up to 128 volume sets per controller.
2. Up to 128 volume sets can be created in a RAID set.
3. The maximum addressable size of a single volume set is not lim­ited to 2TB, because the controller is capable of 64-bit LBA mode.
However the operating system itself may not be capable of ad­dressing more than 2TB.
See Areca website ftp://ftp.areca.com.tw/RaidCards/Docu-
ments/Manual_Spec/ Over2TB_050721.ZIP le for details.
6.6.1 Create Volume Set (0/1/10/3/5/6)
To create volume set from RAID set system, move the cursor bar
to the main menu and click on the “Create Volume Set” link. The “Select The Raid Set To Create On It” screen will show all RAID
set number. Tick on a RAID set number that you want to create
and then click on the “Submit” button.
The new create volume set attribute allows user to select the Volume Name, RAID Level, Capacity, Greater Two TB Volume Support, Initialization Mode, Strip Size, Cache Mode, Tagged Command Queuing, and SCSI Channel/SCSI ID/SCSI Lun.
127
WEB BROWSER-BASED CONFIGURATION
• Volume Name
The default volume name will always appear as “ARC-12x4-VOL”. You can rename the volume set providing it does not exceed the
15 characters limit.
• Volume Raid Level Set the Raid Level for the volume set. Highlight the desired RAID level from the available RAID levels option.
• Capacity
The maximum volume size is the default initial setting. Enter the appropriate volume size to t your application.
• Greater Two TB Volume Support
If volume capacity will exceed 2TB, controller will show the "Greater Two TB Volume Support" sub-menu. Greater Two TB Volume Support option: "No", "64bit LBA" and "4K Block".
- No
It keeps the volume size with max. 2TB limitation.
- 64bit LBA This option uses 16 bytes CDB instead of 10 bytes. The
maximum volume capacity is up to 512TB.
This option works on different OS which supports 16 bytes CDB. Such as: Windows 2003 with SP1 or later
Linux kernel 2.6.x or later
128
WEB BROWSER-BASED CONFIGURATION
- 4K Block
It changes the sector size from default 512 bytes to 4k bytes. The maximum volume capacity is up to 16TB. This option works
under Windows platform only. And it can not be converted to
“Dynamic Disk”, because 4k sector size is not a standard format.
For more details, please download Over2TB manual from http://www.areca.com.tw/support/main.htm
• Initialization Mode
This option is used to dene “Background Initialization”, “Fore­ground Initialization” or “No Init (To Rescue Volume)”. When “Background Initialization”, the initialization proceeds as a
background task, the volume set is fully accessible for system reads and writes. The operating system can instantly access to the newly created arrays without requiring a reboot and waiting
the initialization complete. When “Foreground Initialization”, the
initialization proceeds must be completed before the volume set ready for system accesses. There is no initialization happened
when you select “No Init” option. “No Init“ is for customer to
rescue volume without losing data in the disk.
• Stripe Size
This parameter sets the size of the stripe written to each disk in a RAID 0, 1, 10, 5, 6, 50 or 60 logical drive. You can set the
stripe size to 4 KB, 8 KB, 16 KB, 32 KB, 64 KB, 128 KB, 256KB, 512KB, or 1024KB. A larger stripe size produces better read
performance, especially if your computer does mostly sequential reads. However, if you are sure that your computer does ran­dom reads more often, select a smaller stripe size.
Note:
RAID level 3 and 30 can’t modify the cache strip size.
• Cache Mode
The 6Gb/s SATA RAID controller supports “Write Through” and “Write Back” cache.
129
WEB BROWSER-BASED CONFIGURATION
•Volume Write Protection
When "Volume Write Protection" is enabled on the "Modify Volume Set", host commands fail if they are issued to a volume
in that RAID controller and attempt to modify a volume's data or attributes. Volume Write Protection is used primarily for customer-initiated disaster recovery testing.
• Volume IO Mode:
The Cache IO and Direct IO cache policies apply to read on a
specic virtual disk. The volume IO mode options are as follows:
- Cache Io
Species that all reads are buffered in the controller cache
memory.
- Direct Io
Species that reads are not buffered in cache memory. When
using direct IO mode, data is transferred to the controller cache memory and the host system simultaneously during a read request.
If a subsequent read request requires data from the same data block, it can be read directly from the controller cache memory.
• Tagged Command Queuing
The “Enabled” option is useful for enhancing overall system
performance under multi-tasking operating systems. The Command Tag (Drive Channel) function controls the SATA command tag queuing support for each drive channel. This
function should normally remain “Enabled”. “Disabled” this
function only when using SATA drives that do not support command tag queuing.
• SCSI Channel/SCSI ID/SCSI Lun
SCSI Channel: The 6Gb/s SATA RAID controller function is simu­lated as an external SCSI RAID controller. The host bus is repre­sented as a SCSI channel. Choose the SCSI Channel. SCSI ID: Each SCSI device attached to the SCSI card, as well as the card itself, must be assigned an unique SCSI ID number. A SCSI channel can connect up to 15 devices. The 6Gb/s SATA RAID controller is a large SCSI device. Assign an ID from a list of SCSI IDs.
130
WEB BROWSER-BASED CONFIGURATION
SCSI LUN: Each SCSI ID can support up to 8 LUNs. Most 6Gb/s
SATA controllers treat each LUN like a SATA disk.

function can support the “Volume Modication” function. To expand the last volume set capacity, move the cursor bar to the “Capacity” item and entry the capacity size. When nished the above action, click on the "Sumbit" button to complete the action. The last volume set starts to expand its capacity.
To expand an existing volume noticed:
Only the last volume can expand capacity.
When expand volume capacity, you can’t modify stripe size or
modify RAID level simultaneously.
You can expand volume capacity, but can’t reduce volume capacity size.
After volume expansion, the volume capacity can't be decreased.
For greater 2TB expansion:
If your system installed in the volume, don't expand the volume capacity greater 2TB; except your OS and RAID
controller can support boot up from a greater 2TB capacity device.
Expand over 2TB used LBA64 mode. Please make sure your OS supports LBA64 before expand it.
6.6.4.2 Volume Set Migration
Migrating occurs when a volume set is migrating from one RAID level to another, when a volume set strip size changes, or when a disk is added to a RAID set. Migration state is displayed in the
volume state area of the “Volume Set Information” screen.

Note:
1. If the volume is RAID level 30, 50, or 60, you can not change the volume to another RAID level. If the volume is RAID level 0, 1, 10(1E), 3, 5, or 6, you can not change the volume to RAID level 30, 50, or 60.
2.Power failure may damage the migration data. Please backup the RAID data before you start the migration function.
6.6.5 Check Volume Set
To check a volume set from a RAID set:
(1). Click on the “Check Volume Set” link.
(2). Click on the volume set from the list that you wish to check.
Click on “Conrm The Operation” and click on the “Submit” but­ton. Use this option to verify the correctness of the redundant
data in a volume set. For example, in a system with dedicated
parity, volume set check means computing the parity of the data disk drives and comparing the results to the contents of the dedicated parity disk drive. The checking percentage can also be
viewed by clicking on “RAID Set Hierarchy” in the main menu.
6.6.6 Schedule Volume Check
A volume check is a process that veries the integrity of redun­dant data. To verify RAID 3, 5, 6, 30, 50 or 60 redundancy, a volume check reads all associated data blocks, computes parity,
reads parity, and veries that the computed parity matches the
read parity.
Volume checks are very important because they detect and cor­rect parity errors or bad disk blocks in the drive. A consistency check forces every block on a volume to be read, and any bad blocks are marked; those blocks are not used again. This is criti­cal and important because a bad disk block can prevent a disk rebuild from completing. We strongly recommend that you run consistency checks on a regular basis—at least once per week ( set on ‘Scheduler). Volume checks degrade performance, so you
can also run them when the system is idle (set by “Checking After System Idle”).

Note:
Please make sure of the inconsistency source generated by parity error or bad block before you click the recovery method. Otherwise, you will lose the recovery data.
6.6.7 Stop Volume Set Check
Use this option to stop the “Check Volume Set” function.
6.7 Physical Drive
Choose this option to select a physical disk from the main menu and then perform the operations listed below.
6.7.1 Create Pass-Through Disk
To create pass-through disk, move the mouse cursor to the main
menu and click on the “Create Pass-Through” link. The relative
setting function screen appears. A pass-through disk is not con-
trolled by the 6Gb/s SATA RAID controller rmware; it can’t be a
part of a volume set. The disk is available to the operating system

as an individual disk. It is typically used on a system where the operating system is on a disk not controlled by the RAID rm­ware. The user can also select the Cache Mode, Tagged Command
Queuing, and SCSI channel/SCSI_ID/SCSI_LUN for this pass-
through disk.
6.7.2 Modify Pass-Through Disk
Use this option to modify the pass-through disk attribute. The user can modify the Cache Mode, Tagged Command Queuing, and
SCSI Channel/ID/LUN on an existing pass-through disk.
To modify the pass-through drive attribute from the pass-through
drive pool, move the mouse cursor bar and click on the “Modify Pass-Through” link. The “Select The Pass Through Disk For Modi­cation” screen appears mark the check box for the pass-through disk from the pass-through drive pool and click on the “Submit” button to select drive. When the “Enter Pass-Through Disk Attri­bute” screen appears, modify the drive attribute values, as you want. After you complete the selection, mark the check box for “Conrm The Operation” and click on the “Submit” button to com-
plete the selection action.
