<br></blockquote></div>Hi Vibnu,<div><br></div><div>Strange, you're unable to see the target on either of the nodes? I'm assuming your using the default LVM storage back-end. </div><div><br></div><div>Something to look at:</div>
<blockquote style="margin:0 0 0 40px;border:none;padding:0px"><div>"sudo tgtadm --lld iscsi --op show --mode target" - Make sure your target is present (on the cinder node)</div></blockquote><div><br></div><div>
You shouldn't *need* to do this, but to trouble-shoot you could also try:</div><blockquote style="margin:0 0 0 40px;border:none;padding:0px"><div>"sudo iscsiadm -m discovery -p <a href="http://192.168.150.96:3260">192.168.150.96:3260</a> -t st"</div>
