Function Details

int32_t _ocs_scsi_recv_cmd	(	ocs_io_t *	io,
		uint32_t	lun,
		uint8_t *	cdb,
		uint32_t	cdb_len,
		uint32_t	flags
	)

The IO context (ocs_io_t) structure has an element of type ocs_scsi_tgt_io_t named tgt_io that is declared and used by a target-server for private information.

Parameters

io	Pointer to the IO context.
lun	LUN for this IO.
cdb	Pointer to the SCSI CDB.
cdb_len	Length of the CDB, in bytes.
flags	Command flags.

Returns: Returns 0 on success, or a negative error code value on failure.

int32_t ocs_scsi_del_initiator	(	ocs_node_t *	node,
		ocs_scsi_del_initiator_reason_e	reason
	)

Delete a SCSI initiator node.

Description: Sent by the base driver to notify a target-server that a remote initiator is now gone. The base driver has terminated all outstanding IOs, and the target-server will receive the appropriate completions.

Note: This function is only called if the base driver is enabled for target capability.

Parameters

node	Pointer to the node being deleted.
reason	This is the reason that the initiator was removed and will be one of the following enumeration types: OCS_SCSI_INITIATOR_DELETED or OS_SCSI_INITIATOR_MISSING.

Returns: Returns OCS_SCSI_CALL_COMPLETE to indicate that all work completed.

int32_t ocs_scsi_new_initiator ( ocs_node_t * node )

Receive notification of a new SCSI initiator node.

Description: Sent by the base driver to notify a target-server of the presence of a new remote initiator. The target-server may use this call to prepare for an inbound IO from this node. The ocs_node_t structure has an element of type ocs_scsi_tgt_node_t named tgt_node that is declared and used by a target-server for private information.

Note: This function is only called if the base driver is enabled for target capability.

Parameters

node	Pointer to a new remote initiator node.

Returns: Returns 0 on success, or a negative error code value on failure.

int32_t ocs_scsi_recv_cmd_first_burst	(	ocs_io_t *	io,
		uint32_t	lun,
		uint8_t *	cdb,
		uint32_t	cdb_len,
		uint32_t	flags,
		ocs_dma_t	first_burst_buffers[],
		uint32_t	first_burst_bytes
	)

Receive an FCP SCSI command with the first burst data.

Description: Receive a new FCP SCSI command from the base driver with the first burst data.

Parameters

io	Pointer to the IO context.
lun	LUN for this IO.
cdb	Pointer to the SCSI CDB.
cdb_len	Length of CDB, in bytes.
flags	Command flags.
first_burst_buffers	First burst buffers.
first_burst_bytes	The number of bytes received in the first burst.

Returns: Returns 0 on success, or a negative error code value on failure.

int32_t ocs_scsi_recv_tmf	(	ocs_io_t *	tmfio,
		uint32_t	lun,
		ocs_scsi_tmf_cmd_e	cmd,
		ocs_io_t *	io_to_abort,
		uint32_t	flags
	)

Receive a TMF command IO.

Description

Called by the base driver when a SCSI TMF command has been received. The target-server processes the command, aborting commands as needed, and posts a response using ocs_scsi_send_resp(). The IO context (ocs_io_t) structure has an element of type ocs_scsi_tgt_io_t, named tgt_io that is declared and used by a target-server for private information.

Notes: -If the target-server walks the nodes active_ios linked list, and starts IO abort processing, the code must not abort the IO passed into the ocs_scsi_recv_tmf() command.

This io_to_abort is guaranteed not to be freed during this function's scope. Since ocs_scsi_tgt_abort_io() takes a reference on the io_to_abort, if ocs_scsi_tgt_abort_io() is called within this function's scope, another reference is not needed. If ocs_scsi_tgt_abort_io() isn't called in this context and the io_to_abort pointer needs to be used beyond this function's scope, use ocs_ref_get() to take another reference.

Parameters

tmfio	Pointer to the IO context.
lun	Logical unit value.
cmd	Command request.
io_to_abort	Pointer to the IO object to abort for TASK_ABORT (NULL for all other TMF).
flags	Flags.

Returns: Returns 0 on success, or a negative error code value on failure.

Definition at line 2682 of file ocs_ramd.c.

int32_t ocs_scsi_tgt_del_device ( ocs_t * ocs )

Tears down the target members of the ocs structure.

Description: Called by the OS code when the device is removed.

Parameters

ocs	Pointer to the ocs.

Returns: Returns 0 on success, or a negative error code value on failure.

Definition at line 836 of file ocs_ramd.c.

void ocs_scsi_tgt_del_domain ( ocs_domain_t * domain )

Accept a domain lost notification.

Description: Called by the base driver when a domain goes away. A target-server uses this call to clean up all domain-scoped resources.

Note: For initiator-client back-ends, the ocs_scsi_ini_del_domain() function is called.

Parameters

domain Pointer to the domain.

Returns: None.

Definition at line 902 of file ocs_ramd.c.

void ocs_scsi_tgt_del_sport ( ocs_sport_t * sport )

Accept a SLI Port gone notification.

Description: Called by the base driver when a sport goes away. A target-server uses this call to clean up all sport-scoped resources.

Note: For initiator-client backends, the ocs_scsi_ini_del_sport() function is called.

Parameters

sport Pointer to the sport structure.

Returns: None.

Definition at line 974 of file ocs_ramd.c.

int32_t ocs_scsi_tgt_driver_exit ( void )

Driver-wide clean-up for the target-server.

Description: Called by the OS driver-wide exit/clean-up.

Returns: Returns 0 on success, or a negative error code value on failure.

Definition at line 401 of file ocs_ramd.c.

int32_t ocs_scsi_tgt_driver_init ( void )

Driver-wide initialization for the target-server.

Description: Called by the OS initialization prior to the PCI device discovery.

Returns: Returns 0 on success, or a negative error code value on failure.

Definition at line 753 of file ocs_ramd.c.

int32_t ocs_scsi_tgt_new_domain ( ocs_domain_t * domain )

Accept a new domain notification.

Description: Called by the base driver when a new domain is discovered. A target-server uses this call to prepare for the new remote node notifications coming from the ocs_scsi_new_initiator(). The domain context has the ocs_scsi_tgt_domain_t structure, which is declared by the target-server code and used for target-server private data.

Note: This function will only be called if the base driver has been enabled for target capability. For initiator-client back-ends, the ocs_scsi_ini_new_domain() function is called.

Parameters

domain Pointer to the domain.

Returns: Returns 0 on success, or a negative error code value on failure.

int32_t ocs_scsi_tgt_new_sport ( ocs_sport_t * sport )

Accept a new SLI Port notification.

Description: Called by the base driver when a new SLI Port (sport) is discovered. A target-server uses this call to prepare for new remote node notifications arising from ocs_scsi_new_initiator().

Note: This function will only be called if the base driver has been enabled for target capability. For initiator-client backends, the ocs_scsi_ini_new_sport() function is called.

Parameters

Parameters

node	Pointer to the remote initiator node to validate.

Returns: Returns TRUE if the initiator should be accepted, or FALSE if the initiator should be rejected.
