1 Introduction and General Information Intended Audience To use this product you should have experience in configuring computer equipment. For example, you should be able to install and configure the operating system (OS) to recognize peripherals and you should be able to use software utilities to configure and troubleshoot those installed components.
(the available capacity is only half of the installed capacity). RAID 1 requires a minimum of two disks. Figure 2. RAID 1 – Disk Mirroring Intel RAID SRCU31 Users Guide...
RAID 4 - Data Striping with a Dedicated Parity Drive RAID 4 (Figure 3) works in the same way as RAID 0. The data is striped across the hard disk drives and the controller calculates redundancy data (parity information) that is stored on a separate hard disk drive (P1, P2).
RAID 4 and RAID 5 are particularly suitable for systems with medium to large capacity requirements, due to their efficient ratio of installed and available capacity. RAID 5 requires a minimum of three disks. Figure 4. RAID 5 Intel RAID SRCU31 Users Guide...
RAID 10 - Combination of RAID 1 and RAID 0 RAID 10 is a combination of RAID 0 (Performance) and RAID 1 (Data Security). Unlike RAID 4 and RAID 5, there is no need to calculate parity information. RAID 10 disk arrays offer good performance and data security (Figure 5).
3. Select a drive(s) using <Shift> and arrow keys. Chaining is grayed out before selecting two drives and is available after selecting two drives. 4. Select “Chaining” and press <Enter>. The System will configure the chain set that is now a logical drive. Intel RAID SRCU31 Users Guide...
On the next higher level are the logical drives. Logical drives are introduced to obtain full independence of the physical coordinates of a physical device. This is necessary to easily change the Intel RAID Controller SRCU31 and the channels, IDs, without loosing the data and the information on a specific disk array.
This complete transparency represents the easiest way to operate disk arrays under the operating system. Neither operating system nor the PCI computer need to be involved in the administration of these complex disk array configurations. Intel RAID SRCU31 Users Guide...
Using CD-ROMs, DATs, Tapes, etc. A SCSI device that is not a SCSI hard disk drive or a removable hard disk drive, or that does not behave like one, is called a Non-Direct Access Device. Such a device is not configured with StorCon and does not become a logical drive or host drive.
2 Getting Started What is the Intel RAID Controller SRCU31 Firmware? We refer to firmware as the operating system that controls the Intel RAID Controller SRCU31 with all its functions and capabilities. The firmware exclusively runs on the Intel RAID Controller SRCU31 and is stored in the Flash-RAM on the Intel RAID Controller SRCU31 PCB.
Server Board The RAID firmware has already been programmed into the memory. Prior to installing the Intel RAID Controller SRCU31 into the computer, an approved memory module must be installed in the controller. For a list of approved memory modules refer to:...
The Intel RAID Controller SRCU31 normally comes ready to be immediately installed into the computer server board. However, you may need to reprogram the RAID Firmware that’s located in the flash memory of the Intel RAID Controller SRCU31. Refer to Chapter 7, Firmware Update, for a normal reprogram of the firmware.
Take all precautions to prevent ESD damage before handling the Intel RAID Controller SRCU31. b. Power off all system components and disconnect their power cords.
Remove the Intel RAID Controller SRCU31 from your system. d. On jumper block J7A1, move jumper from position 1-2 to position 2-3. Reinstall the Intel RAID Controller SRCU31 in the PCI slot in which it was previously installed. Reattach the SCSI drives to the adapter card.
How Many Hard Disk Drives Should Be Integrated Into the Disk Array? The number of physical drives the Intel RAID Controller SRCU31 can run determines the maximum number of physical drives in a disk array. The minimum number of hard disk drives required for any array depends of the RAID level you wish to realize.
Hot Fix drive. Intel RAID Controller Hardware Features This section provides a summary of the key features, configuration options, and support interface technology supported by the Intel RAID Controller SRCU31. Architecture Features (HW) Table 3.
This section provides information on supported SCSI technology and form factors. Supported Hard Disk Drive Technology The Intel RAID Controller SRCU31 supports up to 15 different SCSI devices (single hard disk drives, drive enclosures, controllers, CD-ROM’s, tapes, etc). In certain configurations, this number is reduced.
Low Voltage Differential (LVD) Support The Intel RAID Controller SRCU31 supports Ultra-2 LVD SCSI operating at up to 80MB/sec and Ultra160 LVD SCSI operating at up to 160MB/sec. Table 7. Supported SCSI Hard Disk Drive Standards Maximum Cable Length (meters)
Support for Non-Hard Disk Drive SCSI Devices (Non-Direct Access Devices) The Intel RAID Controller SRCU31 will pass through to the host operating system direct access to non-direct access SCSI devices that are connected to a SCSI bus (channel) of the RAID Controller.
Optional RAID Features Implemented in the Intel RAID Controller SRCU31 Adapter Device Limitation Support • RAID Arrays contain Host Drives (at least 1 and up to 16 maximum) Hard Disk Drives up to 30 maximum spanning both channels (all host drives that are...
Firmware Disk Array Operational States for RAID 4/5 An array drive under the Intel RAID Controller SRCU31 firmware operating system can assume seven different operational states: Idle, Ready, Fail, Build, Rebuild, Expand, and Error. Table 9 describes the operational states for RAID 4/5 while Figure 7 is the operational state diagram for RAID 4/5.
This is the normal state of a disk array. Methods for Hard Disk Drive Replacement The Intel RAID Controller SRCU31 and the Intel RAID Controller SRCU31 firmware offer a variety of methods to replace a defective hard disk drive. When to use them depends on the physical environment of the server.

PCI slot number, for example, “[PCI 0/3] 4 MB RAM detected.” The number after the “/” is the slot number of the controller. This will help determine the order of the Intel RAID Controller SRCU31s and which host adapter number is assigned to them by UnixWare.
/etc directory. Before you can use them you have to create a special device file named /dev/ rsrch by means of “link.” This device file has to be placed on a device of an Intel RAID Controller SRCU31 host drive.
Windows 9x/NT/2000, StorCon’s user interface is character-oriented and available for all operating systems. Information on StorCon+ is found in Chapter 8, Storage Console Plus. StorCon is also part of the Intel RAID Controller SRCU31’s Flash-RAM and can be loaded at system boot level by pressing <Ctrl> + <G>.
The StorCon program is available for various operating systems (NetWare 5.1, Windows NT, Windows 2000, Windows 95/98, Linux, and SCO UnixWare). It can be used either locally or remotely. All Intel RAID Controller SRCU31s in a network can be monitored and serviced from one or several workstation(s).
1. Ensure that Windows has been configured to meet all the requirements of the RAID Software Suite setup. 2. If the Intel RAID Controller SRCU31 has not been installed into the computer, then install it before continuing. Consult Chapter 2 for details when installing the Intel RAID Controller SRCU31.
Uninstalling the RAID Software Suite WARNING Uninstalling the RAID Software Suite from a computer that has the operating system installed on a host drive or pass-through disk will result in the inability to reboot the operating system. This could result in data loss. To remove the RAID Software Suite from Windows 2000 follow the instructions below.
5. After file removal finishes, reboot the computer to complete the uninstall. Loading the StorCon Program Under Windows 95/98 The StorCon program for Windows 95/98 is part of the Intel RAID Controller SRCU31 System CD-ROM. To load the program under Windows 95/98, type the following command at the prompt: StorCon <Enter>...
MON4NETB.DLL). The StorCon Program The structure of the Intel RAID Controller SRCU31 firmware has four different levels of hierarchy. Level 1 where the Physical Devices are found, level 2 containing the Logical Drives (made up of one or several physical drives), level 3, the Array Drives, and finally, level 4, the Host Drives.
Table 14 lists the host drive types that can be created with the Intel RAID Controller SRCU31 Firmware. Table 14. Host Drive Types Minimum Number of Hard Disk Type of Host Drives Drive Description of Host Drive Required Disk 1:1 assignment: host drive to hard disk drive (sometimes also called JBOD)
Figure 13. Remote Machine Select Controller After the login procedure StorCon displays a list of Intel RAID Controller SRCU31s which are installed in the server (in this example one SRCU31, see Figure 14). This list includes controller name, the PCI Bus system (0=primary, 1=secondary, etc.) and the PCI slot number, the controller’s features (C=Chaining, 0=RAID 0, 1=RAID 1, 4=RAID 4, 5=RAID 5, 10=RAID 10), and the firmware level.
Use Save Information to create a complete protocol file of the current RAID subsystem including all settings of the Intel RAID Controller SRCU31 and the drives. This file can be used for remote diagnosis.
2. Use “Repair Array Drives” to repair array drives which have failed drives. 3. Use “Configure Controller” to setup the Intel RAID Controller SRCU31. Here, you can change the cache settings, termination, and memory test, etc. 4. Use “Configure Physical Devices” to initialize the devices at the physical level, for example, change the SCSI protocol, transfer rates, etc.
Figure 17. Physical Drive Statistics Use “Cache Statistics” to view the utilization of the Intel RAID Controller SRCU31’s caches (read cache and write cache). This menu also displays the size of the cache in KB and the settings of both caches (on or off). The figures for “cache hits” show how often requests can be serviced out of the cache, for example, without triggering an immediate disk I/O.
The Retries counter records the number of retries to a hard disk drive (the counter is incremented by one unit whenever the Intel RAID Controller SRCU31 retries to access a hard disk drive. If the counter continues to increase, it is likely that the cable is not adequate for the selected data transfer rate (cable is too long, of poor quality or connectors are of poor quality) or that the SCSI bus is not properly terminated (too many terminators on the cable or a missing terminator).
The Grown Defects counter records the number of media defects that have occurred since the device was first operated with an Intel RAID Controller SRCU31. A hard disk drive is in good condition when it has 0 grown defects. Any value greater than 0 indicates a grown defect condition.
Figure 22. Save Information At the end of this protocol is a chronological listing of boot messages and other events stored in the Flash-RAM of the Intel RAID Controller SRCU31. If the buffer is full, the oldest events are deleted first.
Apart from minor differences, this menu option is identical to menu option Configure Host Drives in Advanced Setup, Chapter 7. In Express Setup, the user may not select a stripe size (defaults to 128 KB) or use the Split/Merge functions. Intel RAID SRCU31 Users Guide...
Host Drive States After clicking on Configure Host Drives, StorCon displays a list of existing host drives. In a new system this list shows no host drive entries. In the example in Figure 24 one host drive is available, and it is a RAID 5 array drive (with approximate 17 GB capacity). The status is ready, meaning that this host drive is fully available and redundant.
Page 94
Pressing <F4> delivers level-by-level detailed information on a host drive and its components. This may assist in getting an overview of a specific host drive. After pressing <F5>, the Intel RAID Controller SRCU31 switches the LEDs (if available) of the hard disk drives belonging to that host drive on and off.
In the Choose Type window in Figure 25 all host drive types are displayed (the possible types depend on the number of selected hard disk drives and the firmware level of the Intel RAID Controller SRCU31). Finish the selection by pressing <Enter>.
Figure 28. Drive Status After leaving StorCon or after pressing <F10> (for refresh) the Intel RAID Controller SRCU31 begins the build process on the new host drive. In our example it calculates the parity information and writes it to the hard disk drives.
Page 97
StorCon has to write new header information on the host drives. All data will be lost from the original host drive. The Split Host Drive menu is only available if StorCon is loaded with <Ctrl> + <G> from the Intel RAID Controller SRCU31’s Flash-RAM.
Page 98
Intel RAID Controller SRCU31’s Flash-RAM. Partition Host Drive: This option is not available when loading StorCon from the Flash-RAM of the Intel RAID Controller SRCU31. Before you can partition a new host drive it may become necessary to first reboot the system. The partitioning menu has similar functions as the MS-DOS program FDISK.
Repair Array Drives This function allows the online repair of array drives which show failed drives. After selecting this menu option, StorCon displays a summary of all installed array drives and the number of array drives which are in critical states (Figure 30). In the example in Figure 31 there is one array drive in the Fail state.
See Figure 35. Figure 35. Array Drive Summary The Error state of an array drive is critical. There are several procedures in the Intel RAID Controller SRCU31’s firmware to handle such cases and bring back the array drive into operation without losing data.
Intel RAID Controller SRCU31s is very easy and secure, even if the SCSI IDs and channels are changed. Simply connect the hard disk drives to the new Intel RAID Controller SRCU31, and the host drives will be automatically available. See Figure 37.
Possible SCSI IDs for the channel Firmware Update The firmware, BIOS and StorCon program of the Intel RAID Controller SRCU31 are stored in Flash-RAM which is part of the Intel RAID Controller SRCU31 hardware. In contrast to EPROMs, Flash-RAMs can be reprogrammed many times without the complicated UV-light erasing procedure.
Intel RAID Controller SRCU31. Through this channel the subsystem can report its temperature and the power supply status to the Intel RAID Controller SRCU31. The major objective of SAF-TE or SES is auto hot plug. In contrast to hot plug, auto hot plug allows a defective drive to be simply removed from the subsystem and the replacement unit installed in its place.
(disk shuttles, cables, terminators, etc.). Advanced Settings Within Advanced Settings there are three settings which control the configuration and address behavior of the Intel RAID Controller SRCU31’s BIOS and DPMEM. See Figure 40 and Table 16 for setting details. Figure 40. Advanced Settings Dialog...
The DPMEM address is always above 1 MB. Clear Log Buffer The Intel RAID Controller SRCU31 records certain events in a logging buffer which is part of the Flash-RAM. Clear all events in the buffer when using the Intel RAID Controller SRCU31 in a new system.
This helps to physically identify a specific drive in an array of many drives. By pressing <F8> you can repair the configuration data of a physical drive. If the Intel RAID Controller SRCU31 should ever display during the boot sequence a message like “Detected Primary Configuration Data error, using Secondary,”...
You should always check that they are all “Enabled” or “On.” If the hard disk drive you have selected is an Ultra1 60 device and the Intel RAID Controller SRCU31 has Ultra160 SCSI channels, <F4> “Advanced Configuration,” allows you to configure the so-called “Domain Validation”...
WARNING This option destroys all data on the hard disk. This option checks of the surfaces of the hard disk drive media. The Intel RAID Controller SRCU31 writes and reads certain data patterns and checks them for correctness. After confirming the security request, a progress information is displayed. You can interrupt the Check Surface option by pressing <Esc>.
Enclosure Status After selecting this option you can either view the Enclosure Status or view/configure the enclosure slots. Before you can use the auto hot plug with a SAF-TE subsystem, you must configure the subsystem (more precisely its intelligence, the so-called SEP SAF-TE Enclosure Processor). See Figure 45.
Configure Logical Drives Logical drives (hierarchy level 2) are installed in the Advanced Setup menu. The Configure Logical Drives screen is shown in Figure 48. Figure 48. Select Logical Drive Keyboard Commands Use the <F4> key to lists all hard disk drives of a logical drive. If it is a logical drive of the type Disk, it only consists of one single hard disk drive.
8000 MB. When data is written to this logical drive, the first hard disk drive is filled first, then the second, and so on. Although it is not advisable, logical drives of the type Chain can also be components of array drives. Intel RAID SRCU31 Users Guide...
RAID 10 RAID 0 Combined with RAID 1 Intel RAID Controller SRCU31 can manage up to 35 array drives (with different RAID levels) simultaneously. Obviously, the number of hard disk drives will limit the number of parallel arrays that can be used.
The additional capacity is introduced as a new host drive. If a logical drive fails during the expansion, the expansion process continues until the expansion is finished and the array drive changes into the fail state. Intel RAID SRCU31 Users Guide...
Add RAID 1 Component This function allows you to add to a logical drive which is member of an array drive, another logical drive as a mirror drive (RAID 1). Example: You have configured an array drive with 4 logical drives. One logical drive has failed and the array drive has gone into the fail state.
Obviously, no other hard disk drive may fail until all data has entirely been reconstructed on the hot fix drive (because the system is operating without redundancy) without the array drive going into error mode. Intel RAID SRCU31 Users Guide...
✏ NOTE In some literature, hot fix drives are also referred to as hot spare drives. You can also add or remove hot spare drives using StorCon+. Remove Hot Fix Drive This option allows you to remove a hot fix drive from an existing array drive. Hot Fix Pool Access By selecting the Hot Fix Pool Access option, the access of a specific array drive to the hot fix pool can be enabled or disabled.
For a striping array (RAID 0, 4, 5, 10), the master drive (indicated by “M”) is the first logical drive in the array (see Figure 59). For a RAID 1 array (mirroring) the master drive is the first logical drive in the array that contains the valid data copied to the second logical drive. Intel RAID SRCU31 Users Guide...
After pressing <Enter>, StorCon displays a list of possible RAID levels. See Figure 58. Then StorCon prompts you for the stripe size. This is the size of the stripes into which the data is divided. Valid values are 16KB, 32KB, 64KB or 128KB. The default is 128KB. See Figure 59. Figure 58.
Intel RAID Controller SRCU31’s alarm signal, or because no one checked the file server) increases the risk of data loss should a second hard disk drive fail. Therefore, new redundancy should be created as soon as possible and in an entirely automated manner.
Split/Merge Host Drives and Partition Host Drive are only available if StorCon is loaded with <Ctrl> + <G> from the Intel RAID Controller SRCU31’s Flash-RAM. The additional capacity resulting from an online capacity expansion is shown as another host drive. If you expanded the capacity of the array drive a second time, there would be three host drives belonging to the same array drive.
This option creates a valid and consistent master boot record on the selected host drive and should be carried out on any new host drive on which Windows NT is installed. Never use it on host drives containing valid data, otherwise all data will be lost. Intel RAID SRCU31 Users Guide...
Supported protocols: IPX/SPX, TCP/IP, NetBIOS. • The access to the Intel RAID Controller SRCU31 can be protected by password. The password is encrypted. To install the StorCon+, use the Intel RAID Controller SRCU31 tools program on the Intel RAID Controller SRCU31 System CD-ROM.

SIOP (0-7) WARNING The SCSI bus termination of the Intel RAID Controller SRCU31 must match the existing SCSI cabling and cable termination. If the Intel RAID Controller SRCU31 represents one end of the SCSI bus, its termination must be ON or AUTO. If you change the termination to OFF, it is likely that the SCSI bus will be unstable and the connected devices may fail.
. All data will be lost. Direct Access Devices Direct access devices can be initialized and subsequently used for logical drives. The Intel RAID Controller SRCU31 caches the I/Os of these devices. Logical drives are the components of array drives. These devices are represented in the physical configuration window in Figure 79 and in Table 22.

✏ NOTE The maximum synchronous data transfer rate between a SCSI device and the Intel RAID Controller SRCU31 can be limited. This limitation may become necessary if a particular SCSI cabling does not allow the maximum rate the controller and the drive could achieve. Adjust the synchronous transfer rate in the SCSI parameters / Initialize menu (pdisk_parameters).
SCSI parameters / Initialize menu (pdisk_parameters). De-Initialize a Physical Disk De-initializing a physical drive removes the Intel RAID Controller SRCU31 initialization sectors (terms_initialization). The physical drive cannot be member of a logical drive once it is deinitialized.
Non Direct Access Devices (Raw Devices) Non direct access devices cannot become components of logical drives, array drives or host drives. These devices are controlled by a software driver (for example, an ASPI module), the operating system or by an application. Non direct access devices cannot be initialized or configured in StorCon+.
Create a New Host Drive. Double click to create a new host drive. Normal Host Drive This host drive belongs to the selected Intel RAID Controller SRCU31 on a non-clustering I/O channel. Array Drives Array drives consist of logical drives. They can be fault tolerant, depending on the RAID level.
Physical drives are hard disk drives. Setting changes are not possible here. If you want to change the settings, you must do so in the physical configuration window. Table 28. Physical Drive Icon Physical Disk Use the Physical Configuration window to change disk settings. Intel RAID SRCU31 Users Guide...
Drive No The host drive number. The host drives are reported to the system in order, beginning with the lowest Drive Number. If the corresponding Intel RAID Controller SRCU31 is the first controller in the system, the system will boot from the host drive with the lowest number.
(RAID 0, 5, 10) Data written on RAID 0, 4, 5, or 10 drives is distributed over all drives (striping). The striping size can only be changed at the time the drive is created (standard setting is 32KB). Intel RAID SRCU31 Users Guide...
Invalid/Missing (RAID 1) These two values show the number of invalid/missing drives. In this condition invalid drives exist during the build process (initial copy of data from the master to the slave). Pool Hot Fix Indicates when the pool hot fix (terms_hot_fix) access is enabled or disabled. A pool hot fix drive is a spare drive within the so-called hot fix pool.
To prevent the operating system from crashing and to hinder the unintentional deletion of drives, all partitions on the host drive (and its related host drives if it is split into several host drives) must be deleted before the host drive can be removed. Intel RAID SRCU31 Users Guide...
Create a New Host Drive Double click on the new host drive icon. Only host drives are “visible” to the operating system. The structure of the host drives is not known to the operating system. The operating system does not recognize that a given host drive consists of a number of hard disk drives forming a disk array. To the operating system this host drive simply appears as one single hard disk drive with the capacity of the disk array.
(terms_termination) or hardware error from a defective drive or an overheated drive. After removing the reason of the data corruption you can carry out parity recalculate (logical_precalc) to ensure that the parity information of this disk array becomes valid. Figure 90. Parity Verify Intel RAID SRCU31 Users Guide...
Parity Recalculate Click the right mouse button on the array drive icon. A parity recalculate can be used to repair parity errors which have been previously detected with the parity verify command (logical_pverify). A parity recalculation initiates the same process used for a build on an array drive.

Figure 92. Logical Configuration If you want to add additional drives to the array drive, select them from the box on the left side of the window. It is possible to add more than one drive at a time. If no physical drives are offered, you have to use the “Hot Plug: Add Disk” function first, to add new drives.
(assuming there is no hot fix drive installed in the system). The time without redundancy should be kept as short as possible, not including the time needed to set up the array drive (state build). Intel RAID SRCU31 Users Guide...
Intel RAID Controller SRCU31’s alarm signal, or because no one checked the file server) increases the risk of data loss should a second hard disk drive fail. Therefore, new redundancy should be created as soon as possible and in an entirely automated manner.
After confirmation the logical drive is removed. If the RAID 1 array drive consists of two drives, the RAID 1 array drive disappears and only one logical drive is left. You can create a new RAID 1 array drive by selecting add RAID 1 (logical_add_raid1). Intel RAID SRCU31 Users Guide...
I/O channel as the defective one. The array drive’s state is error and normally all data would be lost. Intel RAID Controller SRCU31 includes some functions that allow the patch of this array drive from the error state into the fail sate. Before the actual patch, the defective drive has to be physically removed from the array drive.
You can monitor the progress of the array build/rebuild by clicking the right mouse button on the host drive and then selecting progress information. ✏ NOTE User traffic on an array drive that is in the build/rebuild state, slows down the build/rebuild process.

(hotplug_replace_drive) function. If a hot fix drive has previously been assigned to an array drive, the Intel RAID Controller SRCU31 will automatically replace the defective drive and start the reconstruction of the data and the redundant information. Therefore, under these circumstances the fail state is only temporary and will be eliminated by the controller itself.
