gives it the highest priority on the SCSI bus. We recommend that you do not change this setting. • SCSI Parity Checking-(Default: Enabled) When set to Enabled, verifies the accuracy of data transfer on the SCSI bus. Leave this setting enabled unless any SCSI device connected to the Ultra3 SCSI Host Bus Adapter does not support SCSI parity. • Host Adapter SCSI Termination-(Default: Automatic) Determines the termination setting for the SCSI host bus adapter. The default setting for both the LVD/SE and SE connectors is Automatic, which allows the SCSI host bus adapter to adjust the termination as needed depending on the configuration of the connected SCSI devices. We recommend that you do not change this setting. Boot Device Options • Boot SCSI ID-(Default: 0) Specifies the SCSI ID of your boot device. We recommend that you do not change the default setting. • Boot LUN Number-(Default: 0) Specifies which LUN (Logical Unit Number) to boot from on your boot device. This setting is not valid unless Multiple LUN Support is Enabled (see "Advanced Configuration Options" on page 19). SCSI Device Configuration SCSI Device Configuration options can be set individually for each connected SCSI device. NOTE To configure settings for a SCSI device, you must know its SCSI ID (see "Using SCSI Disk Utilities" on page 22). • Sync Transfer Rate-(Default: 160) Determines the maximum synchronous data transfer rate that the SCSI host adapter supports. Use the maximum value of 160 MBytes/sec. If a device is not Ultra160, select the transfer rate of the device (80, 53, 40, ...). • Initiate Wide Negotiation-(Default: Yes) When set to Yes, the SCSI host bus adapter attempts 16-bit data transfer (wide negotiation).

not change this setting.
•
SCSI Parity Checking
—(Default:
Enabled
) When set to
Enabled
,
verifies the accuracy of data transfer on the SCSI bus. Leave this setting
enabled unless any SCSI device connected to the Ultra3 SCSI Host Bus
Adapter does not support SCSI parity.
•
Host Adapter SCSI Termination
—(Default:
Automatic
) Determines
the termination setting for the SCSI host bus adapter. The default setting
for both the LVD/SE and SE connectors is
Automatic
, which allows the
SCSI host bus adapter to adjust the termination as needed depending on
the configuration of the connected SCSI devices. We recommend that
you do not change this setting.
Boot Device Options
•
Boot SCSI ID
—(Default:
0
) Specifies the SCSI ID of your boot device.
We recommend that you do not change the default setting.
•
Boot LUN Number
—(Default:
0
) Specifies which LUN (Logical Unit
Number) to boot from on your boot device. This setting is not valid
unless Multiple LUN Support is
Enabled
(see “Advanced Configuration
Options” on page 19).
SCSI Device Configuration
SCSI Device Configuration options can be set individually for each connected
SCSI device.
NOTE
To configure settings for a SCSI device, you must know its SCSI ID
(see “Using SCSI Disk Utilities” on page 22).
