ifp(7D) Devices ifp(7D)NAMEifp - 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 Proto‐
col 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.

DIAGNOSTICS
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<num‐
ber>", where "<number>" is the instance number of the ISP2100 Host Bus
Adapter.
Deviceis 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 struc‐
ture. Driver did not attach to device; SCSI devices will be inac‐
cessible.
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
Unableto 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 commu‐
nicate 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 lux‐
adm(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 inac‐
cessible.
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 inac‐
cessible.
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 inaccessi‐
ble.
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.
Firmwarechecksum 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 hard‐
ware.
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 rou‐
tine 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 recov‐
ery. This will cause all outstanding commands that have been trans‐
ported to the ifp driver to be completed via the scsi_pkt comple‐
tion routine in the target driver with reason of CMD_RESET and sta‐
tus 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.
