Chapter 2 Preinstallation Planning This chapter describes: • SCSI termination • SCSI cabling • SCSI drive preparation • Limitations on mixing various SCSI drive types Mylex disk array controllers are designed to work in a variety of SCSI RAID application environments. Certain configuration steps need to be performed prior to installing the controller into a RAID environment.
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, and it can be built into a controller, a SCSI peripheral device, or it can be a plug placed on the connector at the very end of a SCSI bus. The DAC1164P controller is equipped with automatic SCSI termination circuitry. If the controller is at the end of a SCSI bus, it automatically enables on-board termination.
Preinstallation Planning Figure 2-1. DAC1164P Termination Examples ☛ Note When connecting SCSI devices, it is better to terminate the ends of the SCSI bus itself than it is to terminate the end devices on the bus. This allows hot swap devices to be added or removed from the SCSI bus without affecting termination.
SCSI Cabling The controller supports up to three Ultra2 SCSI channels. Each channel supports up to 15 devices. LVD Mode The controller supports Ultra2 SCSI with LVD. If all drives attached to a controller drive channel support Ultra2 SCSI with LVD, then that channel will operate at 80 MB. This setup allows a maximum SCSI bus length of up to 12 meters. ☛ Note The SCSI bus length can be extended up to 25 meters if only the controller and one drive are on the bus in a point-to-point configuration.
Preinstallation Planning SCSI Drive Preparation 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.

Chapter 4 Controller Start-up This chapter describes: • Start-up procedures • BIOS options • BIOS Configuration Utility • Driver Installation • What to check in case of problems This chapter describes the DAC1164P 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: the BIOS Options sequence and the BIOS Configuration Utility sequence. Either start-up sequence can be skipped by ignoring the and/or the prompt when the computer is started up.
Controller Start-up Setting BIOS Options The available BIOS options are: • BIOS disabled / enabled • CD-ROM boot disabled / disabled • 2GB / 8GB drive geometry BIOS Disable or Enable This option must be enabled in order to toggle the CD-ROM boot and the drive geometry parameters 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 8GByte or 2GByte 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. m 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). Using RAID EzAssist RAID EzAssist, the on-board BIOS Configuration Utility is used to build several types of RAID configurations. Since this is a Quick Installation Guide, only the Automatic Configuration option will be described here.
Using RAID EzAssist ☛ Note If the BIOS has been disabled on the controller, You will need to press Alt–M to enable it (See your controller’s Installation Guide for details). 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).
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 DAC960 Software Kit Installation Guide and User Manual (P/N 771929).

Appendix D 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. m 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.

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.
could be “killed” (taken “offline”) by the controller (its state changed to “dead”). DAC1164 controllers also monitor SCSI bus parity errors and other potential problems. Any disk with too many errors will also be ‘killed’. Disk Media Error Management DAC1164 controllers transparently manage SCSI disk media errors. Disks are programmed to report errors, even ECC-recoverable errors. If ECC EDO RAM is installed, the controller will correct ECC errors.
Glossary Hot Replacement of Disks (Hot Swap) The design of the DAC1164 controllers allows for the replacement of failed hard disk drives without interruption of system service. In the event of a SCSI drive failure on a properly configured system (where the data redundancy features of the controller are used), system service continues without interruption. A message is generated by the system to alert the system operator.
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 RAID RAID stands for Redundant Array of Independent Disks. The DAC1164 controllers implement this technology to connect up to 15 SCSI devices per channel. Several different forms of RAID implementation have been defined. Each form is usually referred to as a “RAID level.” All the RAID levels supported by DAC1164 controllers are shown below. The appropriate RAID level for a system is selected by the system manager or integrator.
Level 10. Combines RAID 0 striping and RAID 1 mirroring spanned across multiple drive groups (super drive group). This level provides redundancy through mirroring. Level 30. Data is “striped” across multiple drive groups (super drive group). Maintains parity information which can be used for data recovery. Level 50. Data is “striped” across multiple drive groups (super drive group). For data redundancy, drives are encoded with rotated parity.
Glossary SCSI Drive States Refers to a SCSI drive’s current operational status. At any given time, a SCSI drive can be in one of five states: READY, ONLINE, STANDBY, DEAD, or REBUILD. The controller stores the state of the attached SCSI drives in its non-volatile memory. This information is retained even after power-off. Hence, if a SCSI disk is labeled DEAD in one session, it will stay in the DEAD state until a change is made either by using a system level utility or after a rebuild.
Rebuild: A SCSI disk drive is in a “rebuild” state... While it is in the process of being rebuilt. During this process, data is regenerated and written to the disk drive. This state is also referred to as ‘Write-Only’ (WRO). 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.
Glossary A “Standby” disk can be created in one of two ways: 3. When a user runs RAID EzAssist, all disks attached to the controller that are NOT configured into any drive group will be automatically labeled as “standby” drives. 3. A disk may also be added (attached at a later time) to a running system and labeled as standby by using the “DAC1164 Software Kit” (see appropriate chapters for DAC1164 utilities for a particular operating system).
Striping Refers to the storing of a sequential block of incoming data across multiple SCSI drives in a group. For example, if there are 3 SCSI drives in a group, the data will be separated into blocks and block 1 of the data will be stored on SCSI drive 1, block 2 on SCSI drive 2, block 3 on SCSI drive 3, block 4 on SCSI drive 1, block 5 on SCSI drive 2 and so on. This storage method increases the disk system throughput by ensuring a balanced load among all drives.
