Emulex 3.4 user manual Driver for Solaris Lpfc Configuration File Reference, LPFC.conf Parameters

Driver for Solaris LPFC – Configuration File Reference

The parameter values listed in Table 3 are applicable to driver version 6.20i or later. If you are using a version previous to 6.20i, see the Emulex Driver for Solaris User Manual for parameter information.

Note: The fcp-bind-WWNN, fcp-bind-WWPN and fcp-bind-DID driver properties do not apply to a specific HBA. They are the global properties. These properties specify a list of persistent bindings. Each entry in this list applies to a specific instance of an HBA. You can only use one type of binding per HBA.

The LPFC.conf file contains all the driver properties that control driver initialization. In the LPFC.conf file, all HBA-specific driver properties have lpfcX-prefix (where X is the driver instance number); e.g., setting lpfc0-lun-queue-depth= 20 makes 20 the default number of maximum commands which can be sent to a single logical unit (disk). The LPFC man page also provides further device property details.

Note: To override a driver parameter for a single driver-loading session, specify it as a driver property to the modload command. For example: # modload /kernel/drv/lpfc automap=0 (for 32-bit platforms) or modload /kernel/drv/sparcv9/lpfc automap=0 (for 64-bit platforms). This will load Emulex's SCSI support driver with automap set to 0 for this session.

Table 3: LPFC.conf Parameters

Property Name	Scope	Default	Min	Max	Dynamic	Comments
ack0	Controller	0	0=Off	1=On	No	Use ACK0 for class 2. If ack0
	Specific					is 1, the HBA will try to use
						ACK0 when running Class 2
						traffic to a device. If the device
						doesn’t support ACK0, then
						the HBA will use ACK1. If
						ack0 is 0, only ACK1 will be
						used when running Class2
						traffic.
