That's a logout to a specific node and dataport. If you're wrong about
the IQN and/or dataport, it's not going to work.
I think you want:
iscsiadm -m node -u
And for good measure:
iscsiadm -m session -u
If you do want to delete specific discovery records and need to identify
the dataport associated with them:
iscsiadm -m discoverydb
... will print them.

If you're going to that extent, you can umount all remote targets,
disable iscsid and iscsi services, reboot, and clear out the various
entries under /var/lib/iscsi/. Leave the directories
(/var/lib/iscsi/*/), but remove the files beneath them.
Note that this is a bit like doing brain surgery with a sledgehammer.
Lacking in finess, but for some jobs, effective.
You might also try posting to the open-iscsi mailing list. I've found
that iscsi is very tempermental and poorly understood by most.
