Already tried many times without results.

One note: there was an initial problem wen I configured the storage.
At first attempt I made an input of wrong password.
I fear the new one was not retained forsome reason

This my debug on host:

[root at ovnode03 ~]# iscsiadm -m discovery -t st -p 192.168.230.101 --discover
192.168.230.101:3260,1 iqn.2013-09.local.localdomain:c6iscsit.target11


[root at ovnode03 ~]# iscsiadm -m node
iqn.2013-09.local.localdomain:c6iscsit.target11 -l
Logging in to [iface: default, target:
iqn.2013-09.local.localdomain:c6iscsit.target11, portal:
192.168.230.101,3260] (multiple)
iscsiadm: Could not login to [iface: default, target:
iqn.2013-09.local.localdomain:c6iscsit.target11, portal:
192.168.230.101,3260].
iscsiadm: initiator reported error (24 - iSCSI login failed due to
authorization failure)
iscsiadm: Could not log into all portals

If I go in
/var/lib/iscsi/send_targets/192.168.230.101,3260

st_config contains:
# BEGIN RECORD 6.2.0.873-17
discovery.startup = manual
discovery.type = sendtargets
discovery.sendtargets.address = 192.168.230.101
discovery.sendtargets.port = 3260
discovery.sendtargets.auth.authmethod = None
discovery.sendtargets.timeo.login_timeout = 15
discovery.sendtargets.use_discoveryd = No
discovery.sendtargets.discoveryd_poll_inval = 30
discovery.sendtargets.reopen_max = 5
discovery.sendtargets.timeo.auth_timeout = 45
discovery.sendtargets.timeo.active_timeout = 30
discovery.sendtargets.iscsi.MaxRecvDataSegmentLength = 32768
# END RECORD

where is recorded che chap configured password on host?

Also, are iscsi and iscsid services to be configured at startup, or is
it vdsm that should take care of starting one or all of them?
In my case I have this kind of config  on host:

iscsi enabled but in failed state
iscsid active but disabled
?
