Plug the Controller Board into any 32-bit or 64-bit PCI Slot Manual No.
Installation Process Preparing the SCSI Drives To prepare the drives for installation, follow these steps: 1. Remove any terminators attached to the drive or set any drive termination jumpers to the disabled position. 2. Set the SCSI IDs on the drives. 3. Enable term power on the drives. Refer to the drive manual for specific information about drive configuration settings. Installing Cables and Setting Termination Please refer to Table 2-3 on page 2-15 for SCSI Formats and Bus Length requirements. 4.
Installation Note In order to ensure an error free environment, the proper cable type designed for a certain SCSI speed must be used, please refer to Table 2-3 on page 2-15. Note To avoid problems caused by mixing drive types, please refer to “Limitations on Mixing SCSI Drives” on page 2-16. SCSI Termination Each end of a SCSI bus must be terminated to maintain proper voltage levels for SCSI control and data signals. The device used for this purpose is called a terminator.
Installation Process 1. Termination - Only Internal or Only External Devices Check that the drive channel is properly terminated according to drawings below, or skip to Step 2 if using both internal and external devices. The AcceleRAID 170 is equipped with automatic SCSI termination circuitry which handles automatic enabling and disabling of on-board termination. For example, if the controller board is at the end of the SCSI bus, it automatically enables on-board termination.
Installation 2. Termination - Both Internal and External Devices Check that the drive channel is properly terminated according to the drawing below. If the controller board is in the middle of the SCSI bus, it automatically disables on-board termination. If some SCSI devices on the channel are connected to the internal connector, and some are connected to the external connector, on the same channel, the two ends of the SCSI bus farthest from the controller board must each be terminated.
Installation Process Setting SCSI Device IDs 4. Set the SCSI ID on the disk drives; ID 7 is reserved for the controller board. See Figure 2-12. Note Each drive must have a unique ID chosen from 0 through 6 or 8 through 15. Be careful not to duplicate a drive address. Remember: ID 7 is reserved for the controller board; therefore, it cannot be used as a disk drive ID. ID’s from 0 through 6 are usually for Narrow, 8-bit devices.
Installation SCSI Cabling The controller supports one Ultra 160 SCSI channel which can support up to 15 SCSI devices (plus the controller itself). LVD Mode The controller supports Ultra 160 SCSI with LVD. If all drives attached to a controller drive channel support Ultra 160 SCSI with LVD, then that channel will operate at a maximum of 160MB/s burst speed. This setup allows a maximum SCSI bus length of up to 12 meters.
Limitations on Mixing SCSI Drives Limitations on Mixing SCSI Drives Narrow with Wide SCSI Drives If you mix narrow and wide SCSI devices on the controller, use a terminator that does not terminate the upper eight bits, and be sure to properly terminate the end of the bus with either a 16-bit terminator or a 16-bit device that has termination enabled.
Chapter 3 Controller Start-up This chapter describes: • Controller Start-up Procedures • BIOS Options Sequence • BIOS Configuration Utility (RAID EzAssist) • Operating System, Device Drivers, GAM, WAM • What to Check in Case of Problems This chapter describes the AcceleRAID 170 RAID controller start-up procedures and messages produced by the BIOS during start-up or re-boot. This chapter also explains three BIOS options that are available for configuring controller operation.
Controller Start-up Controller Start-up The controller start-up procedure is the first step in confirming that the controller is correctly installed and working properly. The start-up procedure should be performed prior to any software configuration. There are two startup sequences: • BIOS Options sequence, and • BIOS Configuration Utility sequence Either start-up sequence can be skipped by ignoring the and/or the prompt when the computer is powered on.
Controller Start-up Setting BIOS Options The available BIOS options are: • BIOS disabled / enabled • CD-ROM boot disabled / enabled • 2GB / 8GB drive geometry BIOS Disable or Enable This option must be enabled in order to toggle the CD-ROM boot parameter shown in the BIOS Options menu. The BIOS must also be enabled in order to boot from any device (e.g., CD-ROM) or system drive configured on the controller, or to access any DOS partition on any drive configured on the controller.
BIOS Options Sequence Enable 8 GByte or 2 GByte Drives This setting affects how the BIOS reads the disk drives for the boot partition. Drive geometries can be toggled between 8 GB and 2 GB. The default is 2 GB. When the drive geometry is changed, the drive should be formatted at the operating system level. Caution Changing this setting after data has been stored will make the data unreadable. If you have already configured your array and have stored data, you should not change this setting.
Controller Start-up Note In the event that the RAID controller needs to be replaced, the current drive geometry will be restored from the configuration on disk (COD). BIOS Configuration Utility (RAID EzAssist) RAID EzAssist, the on-board BIOS Configuration Utility, is used to build several types of RAID configurations. The following limitations apply to Automatic Configuration: • Only one array will be configured using the Automatic Configuration option.
BIOS Configuration Utility (RAID EzAssist) 3. Watch the messages on the screen for the following prompt to be displayed: Press for RAID Configuration options 4. Press Alt–R to get into RAID EzAssist (the configuration utility). 3-6 Note For more detailed information on how to run RAID EzAssist, refer to the RAID EzAssist Configuration Utility User Reference Guide or the Quick Configuration Guide.
Controller Start-up Operating System If an operating system is not already installed on the system, it can be installed on a system disk on the controller. The operating system is installed along with the operating system device drivers. Operating System Device Drivers Device drivers that are compatible with the controller can be found in the Software Kit. For details on how to install and load drivers, refer to the appropriate Disk Array Controller Software Kit Installation Guide and User Manual.
In Case of Problems In Case of Problems If problems are encountered during start-up, check the following: • Check SCSI cabling for loose connections, pin mismatches (make sure pin 1 on the cable matches pin 1 on the connector), bent pins, and damaged or crossed cables. • Check cable length; this includes internal bus lengths in enclosures. • Check termination. • Check SCSI IDs on all drives.

Appendix B AcceleRAID 170 Error Messages Note The firmware you are using may have these messages turned off. However, they are listed here for your reference. Start-up Error Messages The BIOS looks for any initialization message posted by the firmware during the start-up sequence. If a message is found, one of the following errors displays on screen and the installation process aborts.
Installation Abort During the initialization, if the firmware fails to respond to the BIOS inquiry within two minutes, the following message displays: AcceleRAID 170 not responding--no drives installed! The BIOS then inquires the firmware for its version number and other information, and displays the following message: AcceleRAID 170 Firmware Version x.
AcceleRAID 170 Error Messages System Reboot or Power Down Status messages may also be available from LED indicators connected to the controller. The Cache Dirty indicator is especially important when preparing to power-down the system. Caution It is very important to make sure that all data is written to the disk before rebooting or powering down the system, or you may lose data. It is always a good idea to wait for 60 seconds or until all activity stops before resetting or rebooting the system.
System Reboot or Power Down B-4 AcceleRAID 170 Installation Guide
Appendix C PCI Hot Plug Introduction PCI Hot Plug is a feature that allows a PCI card to be replaced while the host system is still running. The term “Hot Plug” is somewhat misleading; the PCI card cannot simply be pulled out of the host system while the card is operating without risk to the card, the system, and the data on the system. In order to replace a Hot Plug PCI card, a software command must be invoked to power off the card slot before the card can be removed.
Implementation • odineb.nlm - This is a module combining the Open Data-link interface and the Novell Event Bus (NEB). The NEB controls the device drivers through the Open Data-link. If the NetWare installation process determines that the server supports PCI Hot Plug and detects the appropriate driver, the installation process adds the following two LOAD commands to the autoexec.ncf file: • LOAD sys:\system\driver_name This command loads the bus driver (for Compaq, this is cpqsbd.nlm).
PCI Hot Plug Windows NT Windows NT requires additional software from the vendor who makes the system. Since this software is not a part of NT, the software needs to be installed after the operating system is loaded. Refer to your vendor's PCI Hot Plug documentation. Caution GAM drivers can stop PCI Hot Plug Boards from unloading. If this problem occurs, stop GAM and unload the GAM drivers before attempting to unload the PCI Hot Plug controller. Known Windows NT Issues • Mylex Software Kit 2.

Appendix D Enclosure Management Introduction Mylex’s AcceleRAID controllers support the industry standard enclosure management protocol SCSI Accessed Fault-Tolerant Enclosures (SAF-TE). This feature allows the host to monitor drive enclosures and detect certain faults or operating environment conditions. The host can make a decision to shut down the system or issue a warning based on the type of fault detected.
SES SES The AcceleRAID 170 supports SES (SCSI Enclosure System) cabinets. Please refer to the documentation supplied with your SES enclosure cabinet for details on how to take advantage of this feature.

Glossary Cache Controller memory used to speed up data transfer to and from a disk. Cache Flush Refers to an operation where all unwritten blocks in a Write-Back Cache are written to the target disk. This operation is necessary before powering down the system. Cache Line Size The Cache Line Size function is set in conjunction with stripe size and represents the size of the data “chunk” that will be read or written at one time.
Disk Failure Detection The controller automatically detects SCSI disk failures. A monitoring process running on the controller checks, among other things, elapsed time on all commands issued to disks. A time-out causes the disk to be “reset” and the command to be retried. If the command times out again, the controller (its state changed to “offline”) could take the disk offline. Mylex RAID controllers also monitor SCSI bus parity errors and other potential problems.
Glossary smallest disk in the group multiplied by the number of disks in the group. For example, if you have 4 disks of 400MB each, and 1 disk of 200MB in a pack, the effective capacity available for use is only 1000MB (5*200), not 1800MB. Hot Replacement of Disks (Hot Swap) The design of the Mylex RAID controllers allows for the replacement of failed hard disk drives without interruption of system service.
Offline: A Logical Drive is in an “offline” state if... No data can be read from it or written to it. System commands issued to offline logical drives are returned with an error status: no operations can be performed on offline logical drives.
Glossary The appropriate RAID level for a system is selected by the system manager or integrator. This decision will be based on which of the following are to be emphasized: Disk Capacity Data Availability (redundancy or fault tolerance) Disk Performance RAID Levels The disk array controllers monitored by this utility support four RAID Advisory Board-approved (RAID 0, RAID 1, RAID 3, RAID 5) and two special RAID levels (RAID 0+1, and JBOD). Level 0.
Note The host operating system drivers and software utilities remain unchanged regardless of the level of RAID installed. The controller makes the physical configuration and RAID level implementation Replacement Table A replacement table contains information regarding which SCSI devices have been replaced by other SCSI devices through standby replacement.
Glossary until a change is made either by using a system level utility or after a rebuild. Each of the states is described below: Ready: A SCSI disk drive is in a “ready” state if it... Is powered on; and Is available to be configured during the current session but remains unconfigured. Online: A SCSI disk drive is in an “online” state if it... Is powered on; and Has been defined as a member of a drive group; and Is operating properly. Standby: A SCSI disk drive is in a “standby” state if it...
Segment Size See “Cache Line Size.” Session Refers to the period of time between any two consecutive system shutdowns. System shutdown may be either a power off/on, or a hardware reset. Standard Disk Drive This term refers to a hard disk drive with SCSI, IDE, or other interface, that is attached to the host system through a standard disk controller.
Glossary Note The standby rebuild will only happen on the SAME Mylex RAID controller, never across Mylex RAID controllers. To use the standby rebuild feature, you should always maintain a standby SCSI disk in your system. When a disk fails, the standby disk will automatically replace the failed drive and the data will be rebuilt. The system administrator can disconnect and remove the bad disk and replace it with a new disk. The administrator can then make this new disk a standby.
System Drives A system drive is equivalent to a “logical” drive. System drives are presented to the operating system as available disk drives, each with a capacity specified by the Mylex RAID controller. Target ID A target ID is the SCSI ID of a device attached to a Mylex RAID controller. Each SCSI channel can have up to 15 attached SCSI devices (target ID from 0 to 6, and 8 to 15).
