Driver for Linux - Installation Section Page 8

Removing a 4.x or 1.x Version of the Driver

If the driver is installed as a module, do the following to remove the existing driver:

1. Shutdown all applications using storage connected through the lpfcdd driver.

2. Unmount all the file systems mounted through lpfcdd.

• If the IP interface of the lpfndd driver is used, shutdown all the lpfndd IP interfaces using

following command:

ifconfig lpfn<n> down

• Remove the lines in /etc/modules.conf file containing lpfcdd or lpfndd.

• Remove the lpfndd and lpfcdd modules by executing:

rmmod lpfndd

rmmod lpfcdd

rm /lib/modules/<kernel-version>/kernel/drivers/scsi/lpfcdd.o

rm /lib/modules/<kernel-version>/kernel/drivers/scsi/lpfndd.o

• If the IP interface is used, remove the IP interface configuration files by executing the

following command:

rm /etc/sysconfig/network-scripts/ifcfg-lpfn*

If the lpfc and lpfndd driver is installed into the kernel source tree, use the following procedure to remove

the lpfc driver from the kernel source tree:

1. Edit /usr/src/linux/drivers/Makefile to remove the following line if it is present:

subdir-$(CONFIG_SCSI_LPFC) += scsi/lpfc

2. Edit /usr/src/linux/drivers/scsi/Config.in file to remove the following line if it is present:

dep_tristate 'Emulex LightPulse Fibre Channel support'

CONFIG_SCSI_LPFC $CONFIG_SCSI

3. Edit /usr/src/linux/drivers/scsi/Makefile to remove the following line if it is present:

obj-$(CONFIG_SCSI_LPFC) += lpfcdd.0

4. Edit /usr/src/linux/drivers/net/Config.in file to remove the following line if it is present:

dep_tristate 'Emulex LightPulse Fibre Channel support'

CONFIG_NET_LPFC $CONFIG_SCSI

Note: This section describes how to remove a 4.x or 1.x version driver. The Emulex 7.1

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 7.1 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 7.1 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.

Note: Driver installation or removal does not save the configuration files (i.e. lpfc.conf,

lpfc.conf.c or lpfc.conf.defs) from previous installations. If you customized any of

these files, we recommend that you copy them to another location so that you have a

record of the changes.
