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:

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

Note –

The adpu320 driver does not support the HostRAID feature found on some Adaptec SCSI controllers. For adpu320 to support a Adaptec SCSI adapter with HostRAID, you must not use any HostRAID features.

Driver Configuration

The adpu320 host bus adapter driver is configured by defining 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
