the iSCSI INITIATOR is only installed in the NodeServer. the tgt (for tgt admin) is only installed in the
iSCSIHost, so the /etc/tgt/targets.conf is only in
the iSCSIHost.<br>
<br></div>From the result, it doesn't look like the Front-end and
NodeServer can well communicate with the iSCSIHost, can access the iSCSI storage partition created under the iSCSIHost target.<br><br></div></div>It is much appreciated if anyone can help with the above.<br><br></div>Thanks kindly,<br>
