AHA-2940UW/OF and AHA-2944UW/OF User’s Guide Board Layout The AHA-2940UW/OF host adapter supports single-ended SCSI devices. The AHA-2944UW/OF host adapter supports differential SCSI devices. The diagrams below identify the SCSI connectors on each host adapter.
Installation Inserting the Host Adapter 1 Remove the cover from the computer case. (If necessary, refer to your computer documentation.) Figure 2-2. Removing the Chassis Cover 2 Locate an unused PCI expansion slot. (This slot is typically white or ivory.) Unscrew the expansion slot bracket that covers the card-slot opening. PCI Slots (usually white or ivory) Figure 2-3. PCI Slot Location The PCI slot must support bus master data transfers, or the host adapter will not work.
AHA-2940UW/OF and AHA-2944UW/OF User’s Guide 3 Insert the host adapter in a 32-bit or 64-bit PCI expansion slot. Press it down firmly so that the contacts are securely seated in the slot and secure it with the screw that you removed in Step 2. Figure 2-4. Host Adapter Installation Installing SCSI Devices Make sure that all SCSI devices have unique SCSI ID’s. (Refer to your device documentation for SCSI ID settings and instructions on manually changing the default settings.
Installation Internal SCSI Devices 1 Install or enable terminators on the device that you plan to install at the end of the internal cable. Then remove or disable terminators on all remaining devices. On most internal SCSI devices, you control termination by setting a jumper or a switch, or by physically removing or installing a resistor module(s). Refer to the device’s documentation to determine how to enable or disable termination on your particular device. This Device Terminated Figure 2-5.
AHA-2940UW/OF and AHA-2944UW/OF User’s Guide 3 Plug one end of the 50-pin or 68-pin internal SCSI cable into the host adapter’s internal SCSI connector. Use a SCSI cable with enough connectors to accommodate all of the internal devices you want to attach. 50-pin Narrow Internal Connection Pin 1 68-pin Wide Internal Connection Pin 1 Figure 2-6. Internal Ribbon Cable Connection Make sure that the colored stripe on one side of the cable is aligned with pin-1 of the host adapter’s connector.
Installation 4 Plug the other end of the internal SCSI cable into the connector on the last internal SCSI device in the chain. This device must be terminated. Make sure the colored stripe on the side of the cable is aligned with pin-1 of the SCSI device’s connector. Pin 1 Figure 2-7. SCSI Cable Connector Location 5 Plug the remaining cable connectors into any remaining internal devices. These devices must not be terminated.
AHA-2940UW/OF and AHA-2944UW/OF User’s Guide External SCSI Devices 1 Plug one end of a 68-pin external SCSI cable into the host adapter’s external SCSI connector. Plug the other end of the external SCSI cable into one of the connectors on the external SCSI device. If you are installing only one external device, enable the device termination or attach a terminating plug to the device. Terminating Plug Figure 2-9.
Installation 4 Install the host adapter device driver, as described in the following section. Installing the Device Driver (Version 2.0 or Later) for Solaris/SPARC 2.5.1 or 2.6 You can install AHA-2940UW/OF and AHA-2944UW/OF device drivers either from a floppy disk or from the Adaptec Web Site. Follow the procedures below to install the device drivers. Installation from a Floppy Disk 1 1 Log on to the Solaris operating system as root.
AHA-2940UW/OF and AHA-2944UW/OF User’s Guide Installation from the Adaptec Web Site 1 2 3 4 Visit the Adaptec web sit at http://www.adaptec.com 5 6 If you are not logged on at root, re-log on as root. Select the Products link. Select the Sun/UltraSparc Solutions link. Follow the links and download the latest driver onto your system. At the superuser prompt (#), type the following command and press Enter: pkgadd -d / dirname /driver.img (where dirname is the location of the downloaded driver.
Installation Configuring SCSI Devices Your host adapters can transfer data up to 40 MBytes per second on each SCSI channel when connected to devices on a wide bus that support UltraSCSI. UltraSCSI and non-UltraSCSI devices can coexist on the same cable, and each device can transfer data at its own negotiated or assigned transfer rate.
AHA-2940UW/OF and AHA-2944UW/OF User’s Guide Troubleshooting Checklist If you have any problems during the installation, check the following items first: ■ Are the power cables and SCSI cables properly connected? ■ Is the host adapter firmly seated and secured in the PCI expansion card slot? ■ Does each SCSI device including the host adapter, have a unique SCSI ID? ■ Is SCSI termination set correctly? If you still haven’t resolved your problem, read on.
▼ ▼ ▼ ▼ 3 Using SCSISelect The SCSISelect utility enables you to change host adapter and SCSI configuration settings directly from your computer’s desktop. SCSISelect also contains utilities that allow you to low-level format or verify the disk media of your SCSI hard disk drives. You can use SCSISelect directly from the P1275 User Interface.
AHA-2940UW/OF and AHA-2944UW/OF User’s Guide 4 To verify the selection, type the following command at the ok prompt: pwd 5 To view the configuration properties of any selected singlechip host adapter, type the following command at the ok prompt: .

Alternate keys, where possible, are provided for terminal emulators that do not support certain keyboard inputs. Key Function ↑ or ↓ Alternate: Space ← or → Alternate: Tab Scrolls through the settings of an option. Enter Accepts the setting for the selected device. ? For some fields, displays a help screen. Esc Returns to the SCSISelect Options menu or aborts an operation.
AHA-2940UW/OF and AHA-2944UW/OF User’s Guide Configuring SCSI Channel Interface Definitions The following four options enable you to configure the SCSI channel interface: ■ Host Adapter SCSI ID— This option allows you to select the single-chip host adapter’s SCSI Initiator ID. The default setting for all models is 7, which has the highest priority on the SCSI bus. Each SCSI device on the bus, including the host adapter, must have a unique SCSI ID.
Using SCSISelect ■ Support for UltraSCSI Speed— This option determines whether the single-chip host adapter negotiates for doublespeed synchronous transfer rates in support of UltraSCSI devices on the selected SCSI bus. The setting of this option affects the values displayed for the Maximum Sync Transfer Rate option available for each SCSI device on the SCSI bus. ■ Host Adapter SCSI Termination— This option enables you to configure the SCSI cable termination on the single-chip host adapter.
AHA-2940UW/OF and AHA-2944UW/OF User’s Guide SCSI Device Configuration The next four options allow you to configure certain parameters for each SCSI device on the SCSI bus. The settings apply to all SCSI IDs, even if they have not been assigned to a device. If you are configuring the active device, use the SCSI Disk Utilities option, which is explained on page 3-10, to determine which SCSI IDs are assigned to which devices.
Using SCSISelect – 10.0 MB/sec for Narrow SCSI If the single-chip host adapter is configured so it will not initiate synchronous data transfers (Initiate Sync Negotiation is set to No), the maximum synchronous transfer rate is the maximum rate the single-chip host adapter accepts from the device during negotiation. ■ Enable Disconnection— This option determines whether the single-chip host adapter will allow the SCSI device to disconnect from the SCSI bus.
AHA-2940UW/OF and AHA-2944UW/OF User’s Guide Using the SCSI Disk Utilities To use the SCSI Disk Utilities option 1 Select SCSI Disk Utilities from the SCSISelect Options screen. SCSISelect immediately scans the active device’s SCSI bus for all devices connected to the single-chip host adapter. SCSISelect displays a list of all SCSI IDs and the devices assigned to them. Figure 3-4 shows an example of a SCSI Disk Utilities target selection screen.
Using SCSISelect 2 3 Use the keys listed in the table below for the SCSI Disk Utilities target selection screen as follows. Alternate keys, where possible, are provided for terminal emulators that do not support certain keyboard inputs: Key Function ↑ or ↓ Alternate: Space Scrolls through the list of SCSI IDs. Enter Accepts the setting for the selected device. Esc Returns to the SCSISelect Options screen, returns to the Target Selection screen, or aborts an operation.
