NAME
ifp - ISP2100 Family Fibre Channel Host Bus Adapter Driver
SYNOPSIS
PCI SUNW,ifp@pci-slot
DESCRIPTION
The ifp Host Bus Adapter is a SCSA compliant nexus driver
for the Qlogic ISP2100/ISP2100A chips. These chips support Fibre Channel Protocol for SCSI on Private Fibre Channel Arbitrated loops.
The ifp driver interfaces with SCSI disk target driver,
ssd(7D), and the SCSI-3 Enclosure Services driver, ssd(7D).
Only SCSI devices of type disk and ses are supported at present time.The ifp driver supports the standard functions provided by
the SCSA interface. It supports auto request sense (cannot be turned off) and tagged queueing by default. The driver requires that all devices have unique hard addresses defined by switch settings in hardware. Devices with conflicting hard addresses will not be accessible.

Unable to map pci config registers Unable to map biu registers Driver was unable to map device registers; check for bad hardware. Driver did not attach to device; SCSI devices will be inaccessible. Cannot alloc tran Driver was unable to obtain a transport handle to be able to communicate with SCSA framework. Driver did not attach to device; SCSI devices will be inaccessible.ddi_create_minor_node failed
Driver was unable to create devctl minor node that is used by luxadm(1M) for administering the loop. Driverdid not attach to device; SCSI devices will be inacces-
sible. Cannot alloc dma handleDriver was unable allocate a dma handle for communicat-
ing with the Host Bus Adapter. Driver did not attach to device; SCSI devices will be inaccessible. Cannot alloc cmd area Driver was unable allocate dma memory for request and response queues. Driver did not attach to device; SCSI devices will be inaccessible. Cannot bind cmd area Driver was unable to bind dma handle to the cmd area. Driver did not attach to device; SCSI devices will be inaccessible. Cannot alloc fcal handle Driver was unable allocate a dma handle for retrieving loop map from the Host Bus Adapter.

Cannot bind portdb Driver was unable to bind fcal port handle to the memory used for obtaining port database. Driver did not attach to device; SCSI devices will be inaccessible.scsi_hba_attach failed
Driver was unable to attach to the SCSA framework. Driver did not attach to device; SCSI devices will be inaccessible. Unable to create hotplug thread Driver was not able to create the kernel thread used for hotplug support. Driver did not attach to device; SCSI devices will be inaccessible. Cannot add intr Driver was not able to add the interrupt routine to the kernel. Driver did not attach to device; SCSI devices will be inaccessible. Unable to attach Driver was unable to attach to the hardware for some reason that may be printed. Driver did not attach to device; SCSI devices will be inaccessible. The following set of messages may be display at any time. They will be printed with the full device pathname followed by the shorter form described above.

Stop firmware failed Stopping the firmware failed; may be bad hardware. Load ram failed Unable to download new firmware into the ISP chip. DMA setup failed The DMA setup failed in the host adapter driver on ascsi_pkt. This will return TRAN_BADPKT to a SCSA target
driver. Bad request pkt type Bad request pkt Bad request pkt hdr Bad req pkt order The ISP Firmware rejected the packet as being set upincorrectly. This will cause the ifp driver to call the
target completion routine with the reason ofCMD_TRAN_ERR set in the scsi_pkt. Check the target
driver for correctly setting up the packet. Firmware error The ISP chip encountered a firmware error of some kind.This error will cause the ifp driver to do error
recovery by resetting the chip. DMA Failure (event) The ISP chip encountered a DMA error while reading from the request queue (event is 8003) or writing to the response queue (event is 8004). This error will causethe ifp driver to do error recovery by resetting the
chip. Fatal error, resetting interfaceThis is an indication that the ifp driver is doing
error recovery. This will cause all outstanding commandsthat have been transported to the ifp driver to be com-
pleted via the scsi_pkt completion routine in the target
driver with reason of CMD_RESET and status of
