NAME

sf - 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 system console.

The first set of messages indicate that the attachment was unsuccessful, 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 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.

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.
