Installation guide

AMD PCscsi, PCscsi II, PCnet-SCSI
Solaris Device Driver:
pcscsi
Device Types: SCSI
Adapter: Qlogic QLA510
Chip: AMD 53C974 (PCscsi)
53C974A (PCscsi II), Am79C974 (PCnet-SCSI)
(SCSI device only)QLogic FAS974
Bus Type: PCI
Systems Supported: PCnet-SCSI chip is embedded in the HP Vectra
XU 5/90 and Compaq XL 560 and XL 590 systems
Preconfiguration Information
Only the SCSI portion of the PCnet-SCSI host bus adapter is discussed here; the net
portion requires a separate Solaris driver (pcn). See the “AMD PCnet Ethernet
(PCnet-ISA, PCnet-PCI), Allied Telesyn AT-1500, Microdyne NE2500plus” on page
10-71 Device Reference Page for configuration information about Ethernet capabilities.
Known Problems and Limitations
Occasional data corruption has occurred when pcn and pcscsi drivers in HP
Vectra XU 590, Compaq XL 560, and Compaq XL 590 series computers are used
under high network and SCSI loads. These drivers do not perform well in a
production server.
A possible workaround is to disable the pcn device with the system BIOS and use
a separate add-in network interface.
The SCSI Tagged Queuing option is not supported.
