8. Power down the system.

9. Restart the system to load new configuration data.

The Configuration File (lpfc.conf)

The lpfc.conf file contains all the variables that control driver initialization.

In the lpfc.conf file, all adapter-specific parameters 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). A value of -1 for an adapter specific parameter will

assign the default value for that parameter as denoted by lpfc_param.

Changes to the /etc/lpfc.conf file require a driver rebuild, a new ramdisk image and driver reload for the

changes to take effect.

If you load the driver with the help of /etc/modules.conf, you can also specify changes to driver

parameters in /etc/modules.conf. For example:

options lpfc lpfc_automap=0 lpfc_bind_entries=1 \

lpfc_fcp_bind_WWPN=50060482c33ed60f:

lpfc1t1

would bind device with WWPN 50060482c33ed60f to target 1, with no other device mapped.

Note: Utilities such as HBAnyware expect to find lpfc.conf installed in /etc directory. If

documented install procedures are followed, a link to lpfc.conf file is automatically

created in the /etc directory.

Note: If you want to override a driver parameter for a single driver-loading session, you can

specify it as a parameter to the insmod command. For example: # insmod ./lpfc.o

lpfc_automap=0. This will load Emulex's SCSI support driver with lpfc_automap set to

0 for this session.

Table 2: lpfc.conf Variables

Variable Default Min Max Comments

lpfc_ack0 0 0=Off 1=On Use ACK0 for class 2.

lpfc_automap 1 0=Off 1=On Automatically assign SCSI

IDs to FCP targets

detected.

lpfc_check_cond_err 0 0=Off 1=On Treat certain FCP check

conditions as FCP RSP

errors.

lpfc_cr_count 1 1 255 This parameter determines

the values for I/O

coalescing for cr_delay

(msec) or cr_count

outstanding commands.
