iSCSI client setup difficulties

I am trying to set up iscsi linux clients and am having some problems. iscsid is running, I can do discovery fine, but adding the iscsi lun I get the following error:

iscsiadm -m node -T iqn.xxxxxxxxxxxxxx -p y.y.y.y:3260 -l Logging in to [iface: default, target: iqn.xxxxxxxxxxxxxx, portal: y.y.y.y,3260] iscsid: session [iqn.xxxxxxxxxxxxxx,y.y.y.y,3260] already running. iscsiadm: Could not login to [iface: default, target: iqn.xxxxxxxxxxxxxx, portal: y.y.y.y,3260]: iscsiadm: initiator reported error (15 - already exists)

So far I have this fully working on centos but this does not work at all on debian with the same command lines copied and pasted to be sure, I get the already exists error every time centos iscsi-initiator-utils-6.2.0.868-0.18.el5 debian open-iscsi 2.0.870~rc3-0.4 Any ideas on this?
