Hi all,

I'm trying to configure the cluster but I'm not having problems, these
are the steps I performed:

Hardware 2 Server HP380G7 with iL0 V3
Storage Fibre Channell HP P2000 G3 FC

1) Configuration multipath.conf
defaults {
        udev_dir                /dev
        polling_interval        10
        selector                "round-robin 0"
        path_grouping_policy    failover
        prio_callout            "/bin/true"
        path_checker            tur
        rr_min_io               100
        rr_weight               uniform
        failback                immediate
        no_path_retry           12
        user_friendly_names     yes

devnode_blacklist {
        devnode         "^(ram|sda|raw|loop|fd|md|dm-|sr|scd|st)[0-9]*"
        devnode         "^hd[a-z]"
        devnode         "^cciss!c[0-9]d[0-9]*"

devices {

device {
       vendor                  "HP"
       product                 "P2000 G3 FC"
       path_grouping_policy    group_by_prio
       path_checker            tur
       path_selector           "round-robin 0"
       prio_callout            "/sbin/mpath_prio_alua /dev/%n"
       rr_weight               uniform
       failback                immediate
       hardware_handler        "0"
       no_path_retry           18
       rr_min_io               100


2) Configuration LVM
pvcreate /dev/mapper/mpath1
vgcreate vg_name /dev/mapper/mpath1
Configuration on all nodes with the option duei shared

3) Configuration Cluster
pvecm create sfarm-kvm

4) Configuration Cluster.conf
<?xml version="1.0"?>
<cluster config_version="4" name="sfarm-kvm">
  <cman keyfile="/var/lib/pve-cluster/corosync.authkey" two_node="1"

<clusternode name="sfarm-kvm1sc" nodeid="1" votes="1">
                <method name="1">
                        <device name="sfarm-kvm1sc" action="reboot"/>
<clusternode name="sfarm-kvm2sc" nodeid="2" votes="1">
                 <method name="1">
                        <device name="sfarm-kvm2sc" action="reboot"/>

        <fencedevice agent="fence_ilo" ipaddr=""
login="hpilologin"  name="sfarm-kvm1sc"  passwd="hpilopword"/>
        <fencedevice agent="fence_ilo" ipaddr=""
login="hpilologin"  name="sfarm-kvm2sc"  passwd="hpilopword"/>


5)Configuration User iLO
username hpilologin passwd hpilopword group admin

6) Edit /etc/default/redhat-cluster-pve
# USE_CCS="yes"

7) Status Fence
# fence_tool ls
fence domain
member count  2
victim count  0
victim now    0
master nodeid 2
wait state    none
members       1 2

Now if I try to test the Fence I get this error:
root at sfarm-kvm1sc ~ # fence_ilo -l hpilologin -p hpilopword -a -o status -v
Unable to connect/login to fencing device

Or tried this way but it should not be:
fence_ilo_mp -l hpilologin -p hpilopword -a -o status -v

If I do a connection test ssh seems to work:

root at sfarm-kvm1sc ~ # ssh hpilologin at
hpilologin at's password:
User:hpilologin logged-in to ILOCZ22160L83.(
iLO 3 Advanced 1.28 at  Jan 13 2012
Server Name:
Server Power: On


Thanks in advance
