Re: targetcli do not show iscsi

[Luigi Tarenga <luigi.tarenga@gmail.com>]

Hi Jerome,
thanks for the promptly reply. I'm not using the -fb branch.
I have installed targetcli from centos rpm:
# rpm -qi fcoe-target-utils-2.0rc1.fb16-5.el6.noarch

Summary     : An administration shell for FCoE storage targets
Description :
An administration shell for TCM/LIO storage targets, most notably
Fiber Channel over Ethernet (FCoE) targets.

I'm not sure what is the initscript you mention. I have in /etc/init.d/:
# ls fcoe-target iscsi*
fcoe-target  iscsi  iscsid

but afaik those are for the initiatior or fcoe-target...

I tryed to manually create the directory but nothing changed:
# ll /sys/kernel/config/target/
total 0
drwxr-xr-x 3 root root    0 Sep 30 10:25 core
drwxr-xr-x 3 root root    0 Sep 30 10:59 iscsi
-r--r--r-- 1 root root 4096 Sep 30 10:59 version
[root@lizard init.d]#
[root@lizard init.d]# targetcli ls
o- / 
......................................................................................................................... 
[...]
   o- backstores 
.............................................................................................................. 
[...]
   | o- block 
.................................................................................................... 
[0 Storage Object]
   | o- fileio 
................................................................................................... 
[0 Storage Object]
   | o- pscsi 
.................................................................................................... 
[0 Storage Object]
   o- loopback 
.......................................................................................................... 
[0 Targets]

the only difference I see is that the module is now used:
iscsi_target_mod      205464  1

and I can't rmmod it.
