Function Details

int32_t ocs_scsi_del_target	(	ocs_node_t *	node,
		ocs_scsi_del_target_reason_e	reason
	)

Delete a SCSI target node.

Description

Sent by base driver to notify a initiator-client that a remote target is now gone. The initiator-client should terminate and cleanup all I/O's associated with the node.

The ocs_node_t structure has and elment of type ocs_scsi_ini_node_t named ni_node that is declared and used by a target-server for private information.

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

Parameters

node	pointer node being deleted
reason	reason for deleting the target

Returns

Returns OCS_SCSI_CALL_ASYNC if target delete is queued for async completion and OCS_SCSI_CALL_COMPLETE if call completed or error.

int32_t ocs_scsi_ini_del_device

(

ocs_t *

ocs

)

Tears down target members of ocs structure.

Description

Called by OS code when device is removed.

Parameters

ocs	pointer to ocs

Returns

returns 0 for success, a negative error code value for failure.

Definition at line 139 of file ocs_ini_stub.c.

void ocs_scsi_ini_del_domain

(

ocs_domain_t *

domain

)

accept domain lost notification

Description

Called by base-driver when a domain goes away. An initiator-client will use this call to clean up all domain scoped resources.

This function will only be called if the base-driver has been enabled for initiator capability.

Note that this call is made to initiator-client backends, the ocs_scsi_tgt_del_domain() function is called to target-server backends.

Parameters

domain

pointer to domain

Returns

returns 0 for success, a negative error code value for failure.

int32_t ocs_scsi_ini_new_device

(

ocs_t *

ocs

)

Initializes any initiator fields on the ocs structure.

Description

Called by OS initialization code when a new device is discovered.

Parameters

ocs	pointer to ocs

Returns

returns 0 for success, a negative error code value for failure.

Definition at line 121 of file ocs_ini_stub.c.

int32_t ocs_scsi_ini_new_domain

(

ocs_domain_t *

domain

)

accept new domain notification

Description

Called by base drive when new domain is discovered. An initiator-client will accept this call to prepare for new remote node notifications arising from ocs_scsi_new_target().

The domain context has the element ocs_scsi_ini_domain_t ini_domain which is declared by the initiator-client code and is used for initiator-client private data.

This function will only be called if the base-driver has been enabled for initiator capability.

Note that this call is made to initiator-client backends, the ocs_scsi_tgt_new_domain() function is called to target-server backends.

Parameters

domain

pointer to domain

Returns

returns 0 for success, a negative error code value for failure.

Definition at line 166 of file ocs_ini_stub.c.

int32_t ocs_scsi_new_target

(

ocs_node_t *

node

)

receive notification of a new SCSI target node

Description

Sent by base driver to notify an initiator-client of the presense of a new remote target. The initiator-server may use this call to prepare for inbound IO from this node.

This function is only called if the base driver is enabled for initiator capability.

Parameters

node	pointer to new remote initiator node

Returns

none
