sf(7D) Devices sf(7D)NAMEsf - SOC+ FC-AL FCP Driver
SYNOPSIS
sf@port,0
DESCRIPTION
The sf driver is a SCSA compliant nexus driver which supports the
Fibre Channel Protocol for SCSI on Private Fibre Channel Arbitrated
loops. An SBus card called the SOC+ card (see socal(7D)) connects the
Fibre Channel loop to the host system.
The sf driver interfaces with the SOC+ device driver, socal(7D), the
SCSI disk target driver, ssd(7D), and the SCSI-3 Enclosure Services
driver, ses(7D). It only supports SCSI devices of type disk and ses.
The sf driver supports the standard functions provided by the SCSA
interface. The driver supports auto request sense 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
In addition to being logged, the messages below may display on the sys‐
tem console.
The first set of messages indicate that the attachment was unsuccess‐
ful, and will only display while the sf driver is initially attempting
to attach. Each message is preceded by sf%d , where %d is the
instance number of the sf 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.
Failed to obtain transport handle
Driver was unable to obtain a transport handle to communicate with
the socal driver. Driver did not attach to device, SCSI devices
will be inaccessible
Failed to allocate command/response pool
Driver was unable to allocate space for commands and responses.
Driver did not attach to device, SCSI devices will be inaccessible.
Failed to allocate kmem cache
Driver was unable to allocate space for the packet cache. Driver
did not attach to device, SCSI devices will be inaccessible.
Failed to allocate dma handle for
Driver was unable to allocate a dma handle for the loop map. Driver
did not attach to device, SCSI devices will be inaccessible.
Failed to allocate lilp map
Driver was unable to allocate space for the loop map. Driver did
not attach to device, SCSI devices will be inaccessible.
Failed to bind dma handle for
Driver was unable to bind a dma handle for the loop map. Driver did
not attach to device, SCSI devices will be inaccessible.
Failed to attach
Driver was unable to attach for some reason that may be printed.
Driver did not attach to device, SCSI devices will be inaccessible.
The next set of messages may display at any time. The full device
pathname, followed by the shorter form described above, will precede
the message.
Invalid lilp map
The driver did not obtain a valid lilp map from the socal driver.
SCSI device will be inaccessible.
Target t, AL-PA x and hard
The device with a switch setting t has an AL-PA x which does not
match its hard address y. The device will not be accessible.
Duplicate switch settings
The driver detected devices with the same switch setting. All such
devices will be 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
The driver does not know the device type reported by the device
with switch setting t.
