  • Page 17: Internal Scsi Devices

    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).
  • Page 18 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.

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.
  • Page 23: Configuring Scsi Devices

    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.
  • Page 24: Troubleshooting Checklist

    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?

  • Page 30: Configuring Scsi Channel Interface Definitions

    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.
  • Page 32: Scsi Device Configuration

    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.
  • Page 33: Advanced Configuration

    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.
