[Xen-API] Attach iSCSi to XCP 1.6

Hi All,
    I have XCP 1.6 running with these settings:
IP eth0: 192.168.1.200 /24
Gateway: 192.168.1.1
DNS name: xcp1.example.com
DNS server: not defined

  I have Openfiler 2.99.2 with these settings:
IP eth0: 192.168.1.201/24
Gateway: 192.168.1.1
DNS name: nas1.example.com
DNS server: not defined
iSCSi shares:3 shares,
** iqn.2006-01.com.example:nas.vms
** iqn.2006-01.com.example:nas.vms-snapshots
** iqn.2006-01.com.example:nas.iso-templates

from command line in Openfiler:

From XCP interface:
1- Disk & Storage Repositories-> Attach Existing Storage Repository
2- Type the root password
3- Select Software iSCSI
4- In New Storage Repository Window, type:
** Name: VMs
** Desc: VMs
** Initiator IQN: iqn.2013-03.com.example:f503e924
** Port number: 3260
** Hostnameof iSCSI target: 192.168.1.201
** username: nasusr
** Password : nasusr password as defined in Openfiler
5- Hit OK
6- XCP show the iSCSI's I have in Openfiler.
7- I choose TPTG 0 iqn.2006-01.com.example:nas.vms
8- Probing for LUNs, I get an error message "(' timed out',)"

But when I go to local command shell and I type these commands, it works:
1- iscsiadm -m discovery -t st -p 192.168.1.201: displays all the iSCSI I have in my openfiler
2- iscsiadm -m node -p 192.168.1.201 --login:  successful on all iSCSI disks
3- fdisk -l: I see all the iSCSI drives with the mention "Donesn't contain a valide partition table"

I tried to apply the fix listed in https://forums2.openfiler.com/index.php?/topic/1564-iscsi-and-xen-server-storage-repository-issue/page__hl__lvm.conf but I could n't find:
- In /etc/rc.sysinit:
          if [ -x /sbin/lvm.static ]; then
                          if /sbin/lvm.static vgscan --mknodes --ignorelockingfailure > /dev/null 2>&1 ; then
                                          action $"Setting up Logical Volume Management:" /sbin/lvm.static vgchange -a y --ignorelockingfailure
                          fi
          fi
- In /etc/rc.sysinit: keyword filter not found

I tried also adding iSCSI using XenCenter 6.1 build 644, but I'm getting the error message: Discovering LUNs failed

My questions:
1- Why I can't attach the iSCSI from the XCP interface : It works from the command line
2- Why fdisk -l says the iSCSI devices are not partitionned but iqn.2006-01.com.example:nas.vms is already ext3 formated in openfiler
