AHA-2940UW/OF and AHA-2944UW/OF Board Locations Note: For detailed information on mixing wide and narrow SCSI devices, refer to the Adaptec web site Connecting 8-Bit and 16-Bit Devices to an Adaptec Wide Host Adapter at http://www.adaptec.com/cables/ Downloaded from www.Manualslib.com...
Installation Inserting the Host Adapter Remove the cover from the computer case. (If necessary, refer to your computer documentation.) Figure 2-2. Removing the Chassis Cover Locate an unused PCI expansion slot. (This slot is typically white or ivory.) Unscrew the expansion slot bracket that covers the card-slot opening.
AHA-2940UW/OF and AHA-2944UW/OF User’s Guide 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.
Installation Internal SCSI Devices 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).

AHA-2940UW/OF and AHA-2944UW/OF User’s Guide 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...
Page 19
Installation 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.
AHA-2940UW/OF and AHA-2944UW/OF User’s Guide External SCSI Devices 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.
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 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 Visit the Adaptec web sit at http://www.adaptec.com Select the Products link. Select the Sun/UltraSparc Solutions link. Follow the links and download the latest driver onto your system. If you are not logged on at root, re-log on as root.
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?
(also known as the Forth prompt, Forth evaluator, or ROM monitor): show-devs From the ok prompt, select the Adaptec single-chip host adapter to be configured. The word select is used to establish a device instance for the adapter. For example, to select a single-...

Using SCSISelect To select an option Press , , or Space to scroll through the options: Configure/View Host Adapter Settings and SCSI Disk Utilities. When the option you want appears at the Select Option prompt, press Enter. To exit SCSISelect, press Esc in the SCSISelect Options screen. Using the Configure/View Host Adapter Settings Select Configure/View Host Adapter Settings from the SCSISelect Options screen.

Using SCSISelect Use the keys listed in the table below for the device configuration screen. Alternate keys, where possible, are provided for terminal emulators that do not support certain keyboard inputs. Function Scrolls through the settings of an option. Alternate: Space Scrolls through the devices (SCSI IDs) of an Alternate: Tab option.
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.
Page 31
Using SCSISelect Support for UltraSCSI Speed— This option determines whether the single-chip host adapter negotiates for double- speed 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.
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.
AHA-2940UW/OF and AHA-2944UW/OF User’s Guide Using the SCSI Disk Utilities To use the SCSI Disk Utilities option 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.

Using SCSISelect 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: Function Scrolls through the list of SCSI IDs. Alternate: Space Enter Accepts the setting for the selected device.
AHA-2940UW/OF and AHA-2944UW/OF User’s Guide Select Verify or Format. These options are explained in the following sections. Using the Verify SCSI Disk Media Utility To use the Verify [SCSI disk media] utility Select Verify. A safety prompt appears to verify the selection (Figure 3-6). -----------------------------Verify----------------------------- This drive will be scanned for media defects.
(Most SCSI disk drives are low-level formatted at the factory.) Adaptec’s Format utility is compatible with most SCSI disk drives. Use the Format utility to format hard disk drives or removable- media drives that were previously used with non-Adaptec host adapters.

AHA-2940UW/OF and AHA-2944UW/OF User’s Guide A safety prompt that verifies the selection appears (Figure 3-8). ------------------------------Format------------------------------ WARNING!!! This drive is about to be low-level formatted. All data on the disk will be erased. Depending on your disk capacity, formatting may take from several seconds to several hours, and once started, cannot be aborted.
