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

Table A-1. Port Settings (Continued)

Parameter	Value	Alias	Description
FW_Fast_Postinga	on, off	n/a	When on, allows posting SCSI command com-
			pletions for multiple SCSI commands during a
			single system interrupt.
FW_Initiator_Modea	on, off	n/a	When on, the HBA is in initiator mode.
FW_Markera	on, off	n/a	When on does not require a marker IOCB to
			resume IOCB processing after a task manage-
			ment mailbox command. When off, the HBA
			rejects any IOCB for a target device affected by
			a task management command until the driver
			issues a marker IOCB to synchronize the SCSI
			request queue between the HBA and the driver.
FW_Sense_Buffer_	on, off	n/a	When on, the HBA expects the last data seg-
Desca			ment descriptor of the data descriptor list associ-
			ated with a Command Type 3 IOCB to be a
			descriptor of a sense buffer.
			When off, the HBA passes any sense data from
			the target in a status IOCB.
FW_ZIO_Enable_Mode	on, off	ZIOE	Enables Zero Interrupt Operation (ZIO) mode.
			When on, the firmware minimizes the number of
			interrupts it generates to the host driver while it
			continues to post completions to the queue.
			When the ZIO count threshold is reached, the
			firmware interrupts the host driver to notify it that
			the queue must be drained. When an I/O com-
			pletes before the ZIO count threshold, the host
			driver is interrupted so it can drain all the I/O
			completions from the queue.
IP_Address	IPv4	IPAD	Target IP address.
	address
IP_ARP_Redirect	on, off	IPARP	When on, MAC addresses are discovered and
			bound to IP addresses for hosts to which the
			HBA wants to talk.
IP_Fragmentationa	on, off	n/a	When on, the HBA cannot fragment IP data-
			grams. When this parameter is off, the HBA
			fragments IP datagrams as necessary.
IP_Gateway	IPv4	IPGW	IP address of the gateway available to the HBA.
	address
IP_Subnet_Mask	IPv4	IPSM	HBA subnet mask xxx.xxx.xxx.xxx.
	address
