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 "AMD PCnet Ethernet (PCnet-ISA, PCnet-PCI, PCnet-PCI II, PCnet-Fast), Allied Telesyn AT-1500, Microdyne NE2500plus, Cabletron E-2210" for configuration information about Ethernet capabilities.

Known Problems and Limitations

• Occasional data corruption has occurred when pcn and pcscsi drivers in HP Vectra XU 5/90 and Compaq Deskpro XL systems 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.
