What does the code 'modprobe -r ib_iser 2/dev/null' do in the script 'open-iscsi'

[vincent . y . guo]

I just found the code :
modprobe -r ib_iser 2/dev/null
in the script open-iscsi,

I am very confused with this code,
if I remove this code from the script, it seems OK.
but when I try to login, it fails,

So what does this code do , and if I really want to remove this code,
what else should I do to replace it?

Thanks.

Re: How to install open-iscsi only by moving files

I also copied the /etc/init.d/open-iscsi

but when I input the command
./open-iscsi start

it reports errors:

;line 11: can't open /etc/init.d/functions

How to install open-iscsi only by moving files

[vincent . y . guo]

I have a open-iscis version (2.0-870.1)  already installed  on a linux
 system.
Now I want to move this version to another linux system(with same
configuration as the one already installed).

I copied the 2 binary files : iscsid and iscsiadm to the folder /usr/
sbin;
then copied the 3 ko files: iscsi_tcp.ko , libiscsi.ko and
scsi_transport_iscsi.ko to the folder //lib/modules/`uname-r`/kernel/
drivers/scsi/

but when I try to start the iscsid, it fails.
What other files shold I copy, or do I need other configurations ?
