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 com‐
mands. The adpu320 driver supports hot swap SCSI and hot plug PCI.
Additionally, the adpu320 driver supports the following features:
· 64-bit addressing (Dual address Cycle)
· PCI-X v1.1 operating up to 133MHz and 64bits
· PCI bus spec v2.2 operating up to 66MHz and 64bits
· Packetized SCSI at 320 and 160 MB/s
· QAS
· DT
· 40MB/sec in single-ended mode and up to 320MB/sec transfer rate in
LVD mode
· Domain Validation
· Retained Training Information (RTI)
· PCI and PCI-X Error handling
Driver Configuration
The adpu320 host bus adapter driver is configured by defining the prop‐
erties 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.
