NAME
adpu320 - Adaptec Ultra320 SCSI host bus adapter driver
SYNOPSIS
scsi@unit-address
DESCRIPTION
The adpu320 host bus adapter driver is a SCSA-compliant
nexus driver that supports the following Adaptec Ultra320
SCSI Devices:
Chips AIC-7902
The adpu320 driver supports standard functions provided by
the SCSA interface, including tagged and untagged queuing,
Wide/Fast/Ultra SCSI, and auto request sense. The adpu320
driver does not support linked commands. The adpu320 driver
supports hot swap SCSI and hot plug PCI.
Additionally, the adpu320 driver supports the following
features:
o 64-bit addressing (Dual address Cycle)
o PCI-X v1.1 operating up to 133MHz and 64bits
o PCI bus spec v2.2 operating up to 66MHz and 64bits
o Packetized SCSI at 320 and 160 MB/s
o QAS
o DT
o 40MB/sec in single-ended mode and up to 320MB/sec
transfer rate in LVD mode
o Domain Validation
o Retained Training Information (RTI)
o PCI and PCI-X Error handling
Driver Configuration
The adpu320 host bus adapter driver is configured by defin-
ing the properties found in adpu320.conf. Properties in the
adpu320.conf file that can be modified by the user include:
ADPU320_SCSI_RD_STRM, ADPU320_SCSI_NLUN_SUPPORT.
-------------------------------------------------------------
Option: ADPU320_SCSI_RD_STRM=[value]
Definition: Enables/disables read streaming negotiation
for all drives.
Possible Values: 0 (off), 1 (on)
Default Value: 0 (off)
Option: ADPU320_SCSI_NLUN_SUPPORT=[value]
Definition: Enables the number of logical units to be
scanned per drive.
Possible Values: 1-64
Default Value: 64
-------------------------------------------------------------
If you alter or add driver parameters incorrectly, you can
render your system inoperable. Use driver parameters with
caution.
