2.3  
Programming the Flash Memory  
The IIR controller normally comes ready to be installed into the computer motherboard  
immediately. However, you may need to reprogram the RAID firmware that is located in  
the flash memory of the IIR controller.  
There are 2 options for programming the firmware, Firmware Update or Firmware  
Recovery. Use the Firmware Update procedure to overwrite the existing firmware with a  
new image (see Appendix A.1). Use the Firmware Recovery procedure to resolve  
problems with the flash memory, for example, if the current firmware programmed in the  
flash is unusable or if a previous firmware update was inadvertently interrupted (see  
2.4  
SCSI Termination  
Termination is a commonly overlooked requirement when connecting SCSI devices  
together. When these devices are connected together, the resulting set of devices is  
typically referred to as a SCSI bus. SCSI devices such as hard disks and tape drives must  
be terminated if they are the last physical devices at either end of the SCSI bus (if nothing  
else is actively terminating the end of the bus such as a terminator or backplane). If a  
device is inserted into the middle of the SCSI bus, then it (the device itself) should not be  
terminated. Only terminate each end of the bus. The modular RAID on motherboard  
(MROMB) design lowers cost by utilizing the SCSI controller and connectors that are  
integrated into the system’s motherboard. With MROMB, termination occurs on the host  
SCSI controller.

3.3.1  
Supported Hard Drive Technology  
The IIR controller supports both Single-ended (SE) and Low Voltage Differential (LVD)  
devices but it is recommended that you use only one type of drive technology (SE or  
LVD) on any one channel at a time.  
The IIR controller supports single-ended drives which operate at up to 40MB/sec  
depending upon the speed of the drives attached.  
The IIR controller supports Ultra-2 LVD SCSI devices operating at up to 80MB/sec,  
Ultra160 LVD SCSI devices operating at up to 160MB/sec, and Ultra320 LVD SCSI  
devices operating at up to 320MB/sec.  
Note: If both SE and LVD devices are attached to the same channel/bus, the entire bus will  
operate at the single ended speed of the slowest device. See Table 3-4 for the maximum  
cable length distances that apply to each mode.  
The IIR controller is designed to use an Ultra160 or Ultra320 SCSI controller  
implementation on the motherboard and is backward compatible with older SCSI hard  
drive specifications. See Table 3-4 for the SCSI standards supported.

2. Use of the word "Narrow", preceding SCSI, Ultra SCSI, or Ultra2 SCSI (for example, Narrow  
SCSI) is optional.  
3. LVD was not defined in the original SCSI standards for this speed. If all devices on the bus  
support LVD, then 12-meters operation is possible at this speed. However, if any device on the  
bus is singled-ended only, then the entire bus switches to single-ended mode and the distances  
in the single-ended column apply.  
4. Single-ended is not defined for speeds beyond Ultra.  
After Ultra2 all new speeds are wide only.  
3.3.2  
Support for Non-Hard-Disk-Drive SCSI Devices (Non-Direct-  
Access Devices)  
The RAID controller will pass through to the host operating system direct access to non-  
direct-access SCSI devices which are connected to a SCSI bus (channel) of the RAID  
controller. The RAID controller passes through all control of these devices to the host  
operating system.  
Types of supported non-Direct-Access SCSI devices (this does not cover specific vendors  
and models):  
SAF-TE Processors  
Tape Backups  
CD-ROMs  
3.4  
RAID Array Drive Roaming  
Array Roaming allows the user the ability to move a complete RAID array from one  
computer system to another computer system and preserve the RAID configuration  
information and user data on that RAID array. ††Compatible RAID controllers must  
control the RAID subsystems of the two computer systems (see list of compatible  
controllers in this section). The transferred RAID array may be brought online while the  
target server continues to run if the hard disk drives and disk enclosure support hot plug  
capabilities; however, not all operating systems support this feature. The hard disk drives  
are not required to have the same SCSI ID in the target system that they did in the original  
system that they are removed from. The RAID array drive that is being roamed must not  
be of type Private. This includes all non-private host, array, and logical drives.  
20  
Hardware Installation and Users Guide  
 
   
Hardware Specifications and Features  
Warning: †† The SRCMRU adapter, with firmware 2.34.yy-Rzzz, is not compatible with all  
previous controllers and firmware versions. Do not attempt RAID Array Drive  
Roaming between RAID controllers that are not compatible with the SRCMRU  
controller. Unpredictable behavior may include, but is not limited to, data loss or  
corruption.  
Compatible controllers include:  
SRCU42L – Firmware version 2.34.yy-Rzzz  
SRCU31LA - Firmware version 2.3x.yy-Rzzz  
SRCU31A– Firmware version 2.3x.yy-Rzzz  
SRCU32 – Firmware version 2.3x.yy-Rzzz  
SRCMRU – Firmware version 2.3x.yy-Rzzz  
SRCZCR – Firmware version 2.3x.yy-Rzzz  
Note: Compatibility refers only to how data and RAID configuration information are written to  
the hard disks. Compatible adapters have the same data file format.  
3.5  
Optional Features  
There are no optional features for this product.  
3.6  
RAID Controller Drive Limitations (Host, Array,  
Logical, and Physical)  
The following are limitations assuming the following:  
U160 or U320 speed depending on the SCSI controller on the motherboard  
Dual channel SCSI controller  
Cabling that meets U160 or U320 specifications depending on the SCSI controller  
Physical drives are limited by the number of SCSI channels being controlled by the  
RAID controller. The firmware/software supports a maximum of 15 hard disk drives per  
channel (or 14 if one SCSI ID is being occupied by an intelligent enclosure processor).  
The maximum number of array drives is limited to 35 by the RAID firmware. The actual  
maximum limit of the SRCMRU RAID controller is 15, see Table 3-5. The firmware  
supports channel spanning where an array can consist of physical drives that are attached  
to either one or to both channels of the RAID controller. An array drive requires a  
minimum of two hard disk drives (or logical drives). Therefore the maximum array  
limitation for each RAID controller is the physical drive limit of that RAID controller  
divided by two. An array drive can contain (or have reside on it) up to a maximum of 2  
host drives.  
Hardware Installation and Users Guide  
21  
 
     
Hardware Specifications and Features  
RAID firmware limits the controller to a maximum of 30 host drives (RAID volumes) per  
controller. There is a minimum of at least one host drive per array drive. A host drive can  
only be associated with (or reside on) a single array drive. Like array drives, host drives  
can reside on hard disk drives that are isolated to a single channel or span both of the  
channels of the RAID controller.

A.1  
Firmware Update Procedure via XROM StorCon  
The Storage Console (StorCon) is a full-featured monitoring and configuration utility with  
a text-based user interface. StorCon manages all aspects of the RAID subsystem as well as  
many features of the RAID adapter. Refer to the Software Guide for more details about  
StorCon.  
You can use StorCon to update the firmware image. The menu option, Firmware Update,  
allows you to update the firmware, BIOS and expansion ROM (XROM) StorCon  
currently programmed on the flash memory of the IIR controller. Because the Flash-RAM  
can be reprogrammed many times, the software modules can be easily updated, without  
having to remove the controller from its PCI slot.  
The firmware, BIOS and XROM StorCon are part of the file, SRC_RXFW.xxx, where the  
file extension xxx indicates the version stepping. The current firmware file can be found  
on the RAID Software Suite CD-ROM. To get the latest firmware for the IIR controller,  
Note: The Firmware Update option is not available when StorCon is accessing the IIR  
Controller remotely.  
Follow the procedure below to update the firmware via XROM StorCon.  
1. Download the firmware image containing the latest programs/drivers from the  
website. Format a 3.5” HD disk (1.44MB) and copy the SRC_RXFW file onto the  
disk.  
2. With the adapter installed in the system, boot the computer and press <Ctrl>+<G>  
when prompted to enter the BIOS version of StorCon.  
3. Select the applicable IIR controller and press <Enter>.  
4. If the Express Setup menu is displayed, press <F4> to display the Advanced Setup  
menu. Select the menu option, Configure Controller and press <Enter>. Insert the  
floppy containing the latest firmware file into the floppy disk drive.  
5. From the Configure Controller submenu, select Firmware Update and press <Enter>.  
6. XROM StorCon automatically searches for the firmware file from the floppy drive, a:\.  
After finding the file, StorCon displays the name, description and version of the  
firmware. Press <Enter>.  
7. StorCon reads and checks the firmware file, then displays a warning. Press <Y> to  
confirm the firmware update.  
8. StorCon programs the flash eprom.

Warning: Do not interrupt the update process to avoid damaging the firmware image in the  
Flash. If the firmware is interrupted you will need to follow the firmware recovery  
process in the next section.  
After StorCon indicates that the update is complete, press any key.  
9. The focus returns to the Configure Controller submenu. Press <Esc> several times to  
close the menus and press <Y> to quit StorCon.  
10.StorCon detects the firmware update and requires a system reboot. Press any key to  
reboot.  
When the update process has completed, reboot the computer for the change to take effect.  
During boot up, the system displays the updated firmware version. You can also relaunch  
StorCon and select the applicable IIR controller to view its new firmware version at the  
bottom of the console (for example, FW:2.32.00-Rxxx).  
You can also use the OS version of StorCon to update the firmware. Refer to the Storage  
Console chapter of the Software Guide for more details.

Firmware Recovery Procedure via Flash Recovery  
Utility (FRU)  
1. Set the IIR controller’s IOP to Reset (Flash Recovery) mode:  
Warning: Shock hazards may be present inside the unit in which this card is being installed.  
Disconnect all power cords to the unit before removal of any covers. Follow the  
warnings noted in your computers user or service manual before installing this  
board. ONLY after all the covers are reinstalled should you reconnect the power  
cords and power up the unit for the software installation and use.  
a. Take all precautions to prevent ESD damage before handling the IIR controller.  
b. Power off all system components and disconnect their power cords.  
c. Remove the cover from the system to gain access to the RAIDIOS PCI slots.  
d. Remove the IIR controller from your system.  
e. On jumper block J1B1, move the jumper from position 2-3 to position 1-2 (see  
Figure A-1). Re-install the adapter in the RAIDIOS PCI slot in which it was  
previously installed.  
f. Replace the cover, reconnect all power cords and power up the system.

2. Change your computer’s BIOS setting so that your system boots from the CD-ROM.  
3. Use the RAID Software Suite CD-ROM to flash the firmware.  
a. Boot the computer with the bootable RAID Software Suite CD-ROM that  
contains the version of the RAID firmware that you wish to recover.  
b. At the ROM-DOS Startup menu, select the option, Flash Recovery Utility, and  
press <Enter>.  
c. The Flash Recovery Utility detects any IIR controllers that are in reset mode and  
lists them in the order that they are found.  
Note: Any IIR controllers that are not in reset mode will not be listed. If no  
controllers are listed, your controller may not be in reset mode. Shut down the  
system and start again with step 1 above. Refer to Figure A-1 to set the jumper in  
reset mode.  
d. Type a controller number to start the recovery process for the firmware on that  
controller. You do not need to press Enter after typing the number. You will see  
the messages shown below during a successful recovery. Each message provides  
a percent complete status while the action is in progress. The entire process may  
take several minutes.
