void zfcp_cfdc_adapter_access_changed

(

struct zfcp_adapter *

adapter

)

zfcp_cfdc_adapter_access_changed - Process change in adapter ACT : Adapter where the Access Control Table (ACT) changed

After a change in the adapter ACT, check if access to any previously denied resources is now possible.

void zfcp_cfdc_lun_denied	(	struct scsi_device *	sdev,
		union fsf_status_qual *	qual
	)

zfcp_cfdc_lun_denied - Process "access denied" for LUN : The SCSI device / LUN where the access has been denied : The FSF status qualifier for the access denied FSF status

Definition at line 343 of file zfcp_cfdc.c.

void zfcp_cfdc_lun_shrng_vltn	(	struct scsi_device *	sdev,
		union fsf_status_qual *	qual
	)

zfcp_cfdc_lun_shrng_vltn - Evaluate LUN sharing violation status : The LUN / SCSI device where sharing violation occurred : The FSF status qualifier from the LUN sharing violation

Definition at line 367 of file zfcp_cfdc.c.

int zfcp_cfdc_open_lun_eval	(	struct scsi_device *	sdev,
		struct fsf_qtcb_bottom_support *	bottom
	)

zfcp_cfdc_open_lun_eval - Eval access ctrl. status for successful "open lun" : The SCSI device / LUN where to evaluate the status : The qtcb bottom with the status from the "open lun"

Returns: 0 if LUN is usable, -EACCES if the access control table reports an unsupported configuration.
