You don't give us any details that would let us help you. You don't tell us version/distro of Linux, what kind of machine (Virtual? 'Real'?), running on what kind of hardware, or what you've done so far.
See the man pages of iscsiadm and tgtadm.
You *SHOULD* be able to rescan the LUN's, but without details, we can't tell you much more. Also, if this is important data, do you not have a backup of it, and why did you just remove the initiators?
