Fallback Sync

Rate (MB/s)

Choices: 40/20, 20/10, and 10/5
Default: 40/20
Speci

es the maximum synchronous transfer rate to be negotiated when the

adapter detects a Single-Ended SCSI bus. The bus is Single-Ended when Ultra

SCSI devices are connected to the bus.

Bus Reset Delay

(sec)

Read only; no choices
Default: 3
The time delay between the reset of the SCSI bus and the scanning of the

SCSI bus. This is a read-only parameter.

Quick Arbitrate

& Select

Choices: Disabled, Enabled
Default: Enabled
If enabled, improves performance by reducing the time required to gain

control of the SCSI bus. QAS can only be enabled if all target settings are set

Sync DT-IU

and all devices on the bus support QAS.

LUNs

Choices: Disable ID, 0, 0–7, 0–63
Default: 0–7
Speci

es the number of LUNs that the driver addresses when scanning for

devices, determined as follows:
• Disable ID: Target ID is bypassed and not scanned
• 0: Scan LUN 0 for this target ID
• 0–7: Scan LUNs 0 to 7 for this target ID
• 0–63: Scan LUNs 0 to 63 for this target ID

Allow Disconnect

Choices: Enabled, Disabled
Default: Enabled
Speci

es whether a device is allowed to disconnect from the SCSI bus during

SCSI command processing. The device determines when it disconnects. This

setting does not force the device to disconnect.

Tagged Com-

mand Queuing

Choices: Enabled, Disabled
Default: Enabled
Speci

es the driver if SCSI commands can use the Tag Command feature to

send multiple commands to a device.

Sync Offset

Choices: 0–127
Default: 127
The defaults offer the best performance possible. The value should not be

changed unless instructed by an HP Support representative.

Sync Enabled for

this ID

Choices: Enabled, Disabled
Default: Enabled
Speci

es whether the selected target transfers data as synchronous transfer

rates or at the asynchronous rate. The maximum synchronous rate to negotiate

is speci

ed in the Sync Rate parameter.
