The Configuration File (lpfc.conf)

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

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.

In the lpfc.conf file, all adapter-specific parameters have lpfcX_ prefix (where X is the

driver instance number); e.g., setting lpfc0_num_iocbs = 2000 allocates 2000 I/O control

blocks for the driver interface lpfc0. 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 and reload for the changes to take

effect.

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 ./lpfcdd.o lpfc_automap=0

This will load Emulex's SCSI support driver with

lpfc_automap set to 0 for this session.

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 lpfcdd 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.
