Updating The Driver from a Previous Version

Note

This section describes how to update a previous

installation of an earlier driver with the 2.01g driver. The

Emulex 2.01g driver adds several new configuration

parameters and renames a couple of previous parameters.

Do NOT replace the current lpfc.conf with lpfc.conf.c or lpfc.

conf.defs or lpfc.conf from a previous release. With the

2.01g driver, all configuration parameters are set in the /etc/

lpfc.conf file. There is no lpfc.conf.c or lpfc.conf.defs file

present in the 2.01g release. To reuse the old

configuration, you must backup the previous lpfc.conf.defs,

lpfc.conf and lpfc.conf.c file and merge configuration in

these files to /etc/lpfc.conf file after installing the new driver

and before building the new driver.

To update a previous version of the lpfc driver:

1. Backup the old lpfc.conf.c file, lpfc.conf file and lpfc.conf.defs file by executing the

following commands:

cd <old_install_source_directory>

cp lpfc.conf.defs /tmp/lpfc.conf.def

cp lpfc.conf.c /tmp/lpfc.conf.c

cp lpfc.conf /tmp/lpfc.conf

2. Remove the old driver installation as described in the Remove Previous Driver

section of this manual.

3. Install the new driver as described in the appropriate installation instructions in this

manual.

4. If you want to reuse the old configuration, merge the old configuration files saved

in /tmp/lpfc.conf.c, /tmp/lpfc.conf and /tmp/lpfc.conf.defs to the /etc/lpfc.conf file.

The parameters listed below are different in 2.01g release. All other parameters in /

etc/lpfc.conf are identical to the ones in /tmp/lpfc.conf.def or /tmp/lpfc.conf.c or /tmp/

lpfc.conf.

❍ lpfc_log_verbose parameter has new bit field added to control logging ioctl

events.

❍ lpfc_fcp_bind_method is a new parameter.
