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.

The messages described below are some that may appear on the system console, as well as being logged.

This first set of messages may be displayed while the ifp driver is initially trying to attach. All of these messages mean that the ifp driver was unable to attach. These messages are preceded by "ifp<number>", where "<number>" is the instance number of the ISP2100 Host Bus Adapter.

Device is using a hilevel intr, unused

The device was configured with an interrupt level that cannot be used with this ifp driver. Check the device.

Failed to alloc soft state

Driver was unable to allocate space for the internal state structure. Driver did not attach to device; SCSI devices will be inaccessible.

Bad soft state

Driver requested an invalid internal state structure. Driver did not attach to device; SCSI devices will be inaccessible.

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. Driver did not attach to device; SCSI devices will be inaccessible.

Cannot alloc dma handle

Driver was unable allocate a dma handle for communicating 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. Driver did not attach to device; SCSI devices will be inaccessible.

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.

Firmware checksum incorrect

Firmware has an invalid checksum and will not be downloaded.

Chip reset timeout

ISP chip failed to reset in the time allocated; may be bad hardware.

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 a scsi_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 up incorrectly. This will cause the ifp driver to call the target completion routine with the reason of CMD_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 cause the ifp driver to do error recovery by resetting the chip.

Fatal error, resetting interface

This is an indication that the ifp driver is doing error recovery. This will cause all outstanding commands that have been transported to the ifp driver to be completed via the scsi_pkt completion routine in the target driver with reason of CMD_RESET and status of STAT_BUS_RESET set in the scsi_pkt.

target t, duplicate port wwns

The driver detected target t to be having the same port WWN as a different target; this is not supposed to happen. Target t will become inaccessible.

target t, duplicate switch settings

The driver detected devices with the same switch setting t. All such devices will become inaccessible.

WWN changed on target t

The World Wide Name (WWN) has changed on the device with switch setting t.

target t, unknown device type dt

The driver does not know the device type dt reported by the device with switch setting t.
