Configuring Multiple SCSI Controllers The AHA-2940/W/UW SCSI controller is used as an example in the following discussion. To use multiple PCI SCSI controllers, do the following: • Install the boot SCSI controller in the lowest PCI Device number. The Device number is determined by the slot number on the PCI bus.
Disk Drives Over 1 Gbyte 4.4.1 Extended Translation Adaptec SCSI controllers have always supported the full range of disk drive capacities under all major operating systems. As disk drives have recently grown beyond 1 GByte in formatted capacity, they have run up against the DOS 1024- cylinder limit.
4.4.3 When to Use Extended Translation Drives With Mixed Partitions Use standard translation, not extended translation, on drives formatted with two or more partitions for different operating systems. Partitions for UNIX and NetWare can be larger than 1 GByte when using standard translation. The term UNIX, as used here, includes all versions of AT&T/USL UNIX, SCO v3.2.4 (or later), and ISC v3.0 (or later).
SCSI Troubleshooting Checklist The AIC-7880 SCSI controller has been tested for compatibility with a wide range of SCSI devices. Most problems that occur during installation result from errors in preparing and connecting devices on the SCSI bus. Answer these questions first if a problem occurs during installation: •...
BIOS Startup Messages After you have configured your SCSI controller, the SCSI controller BIOS displays a message when you boot your computer. Normally, this message lists the SCSI ID, manufacturer, model number and other information for each SCSI device that the BIOS detects.
Perform a SCSI low-level format with the Format Disk utility under SCSI Disk Utilities in the SCSISelect utility. All data on the target drive will be lost when you run the Format Disk utility. Back up your data before you run it! In the SCSISelect Advanced Configuration Options menu, set Extended BIOS - Translation to Enabled.
4.6.2 Start unit request failed The BIOS was unable to send a Start Unit Command to the device. Run the SCSISelect utility and disable Send Start Unit Command for the device. Time-out failure during SCSI Inquiry command! Time-out failure during SCSI Test Unit Ready command! Time-out failure during Start Unit command! An unexpected time-out occurred.
Booting the Computer from a SCSI Drive The following items may apply for multiple SCSI controller configurations. See the section “Configuring Multiple SCSI Controllers” for more detailed information. • Be sure that both standard hard disks are mapped out of the computer using the Setup program by setting the Setup program to Onboard IDE-Disabled.
• Disable Onboard SCSI Boot in Setup. • Be sure that the SCSI drive to be used as drive D is set to SCSI ID 0. Check the drive manual for information on setting the SCSI ID for that device. You can also use the SCSISelect utility to determine the SCSI addresses of peripherals on the SCSI bus.
• Be sure to cycle the power OFF and ON after changing any values on a SCSI controller, in a Setup program, or on a SCSI device. This ensures that the new initial values are loaded. • Be sure that SCSI parity checking is consistently enabled or disabled on all devices on the SCSI bus.

$SSHQGL[ % 'ULYH 7UD\ 0DQDJHPHQW 6\VWHP '706 )HDWXUHV The BP-W8 wide SCSI backplane subsystem consists of a backplane board and drive trays that support wide SCSI hard disk drives. The BP-W8 backplane is specifically designed for a tower housing that accommodates up to eight SCSI drives.
-XPSHU 6HWWLQJV The backplane has two jumpers, J3 and J4, that allow you to select the terminator power source. J3 supports the four upper drive slots (slots 1, 2, 3, and 4) on the backplane. J4 supports the four lower drive slots (slots 5, 6, 7, and 8). Figure B-2 shows the settings for jumpers J3 and J4.
Some versions of the backplane board come with a 6-pin J3 and J4 jumpers. The two additional pins are for setting more hard disk IDs. Note that the hard disk ID switches in these versions have only three on/off switches. See section 4 for details on hard disk ID settings.
+DUG 'LVN ,' 6HWWLQJ 2SWLRQV The wide SCSI hot-swap drive tray includes an 8/12-pin ID cable (see Figure 2). This cable allows you to define the hard disk ID using the ID switches on the backplane board. The narrow SCSI drive tray comes with a 6-pin ID connector but no cable since narrow SCSI drive specifications vary depending on the brand.
Figure B-5 shows the ID switch default settings with the corresponding hard disk IDs for backplane boards with 4-pin J3 and J4 jumpers, and 4-on/off ID switches.
