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" 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.
