A– Port- and HBA-level Parameters Port-level Parameters

Table A-1. Port Settings (Continued)

Parameter	Value	Alias	Description
iSCSI_Data_PDU_In_	on, off	n/a	When on, the system driver reports the DataP-
Ordera			DUInOrder value negotiated during login to the
			HBA firmware.
iSCSI_Data_Seq_In_	on, of	n/a	When on, the system driver reports the DataSe-
Ordera			quenceInOrder value negotiated during login to
			the HBA firmware.
iSCSI_Discovery_Logout	on, off	ID	When on, the HBA initiates an iSCSI logout on a
			discovery session when discovery is complete
			(before closing the connection). When off, the
			HBA closes the TCP connection when discovery
			is complete.
iSCSI_Error_Recovery_	on, off	n/a	When on, the HBA supports iSCSI error recov-
Levela			ery level 0. At this level, the HBA closes a con-
			nection if it detects any errors.
iSCSI_Header_Digests	on, off	IHD	When on, iSCSi headers with CRC protection
			can be transmitted. In addition, incoming iSCSI
			headers are validated and CRC protection is
			removed.
iSCSI_Immediate_Data	on, off	IID	When on, the HBA firmware negotiates (during
			login phase) for Immediate Data=yes. When off,
			immediate data is disabled and the firmware
			negotiates for ImmediateData=no.
iSCSI_Initial_R2T	on, off	IIR2T	When on, the HBA negotiates (during login) for
			InitialR2T=yes. When off, initial R2T is disabled
			and the HBA negotiates for InitialR2T=no.
iSCSI_Send_Markersa	on, off	n/a	Not supported.
iSCSI_Snack	on, off	ISNACK	When on and the FW_Initiator_Mode parameter
			is on, the HBA firmware sends SNACK requests
			to the target when it detects missing PDUs.
			When off and the FW_Initiator_Mode parameter
			is on, the firmware aborts the command and/or
			closes the connection when missing PDUs are
			detected.
iSCSI_Strict_Login	on, off	IS	When on, the HBA adheres to the iSCSI login
			rules, and therefore cannot operate with targets
			that do not conform to these rules. When off, the
			iSCSI login rules are relaxed, and the HBA can
			operate with targets that do not conform to these
			rules.
