Removing a Previous Version of the Driver
Note
This section describes how to remove a previous
installation of an earlier 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.
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 a another
location so that you have a record of the changes.
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 lpfcdd and lpfndd modules by executing:
rmmod lpfcdd
rmmod lpfndd
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*
