iscsiadm documentation is trash!
Linux sometimes truncates LUN name when they are long enough (historical design
flaw, and they usually are), and you may fail to uniquely locate your iSCSI
device with lsscsi if they unfortunately share a prefix.
Use the most verbose iscsiadm output to get the IQN and its device name of an
active session.
# iscsiadm --mode session -P3 # print session info with detail of level 3
