To get information about running sessions, run:

iscsiadm -m session -P 2

This command displays the session/device state, session ID (sid) and some negotiated parameters.

For shorter output (for example, to display only the sid-to-node mapping), run:

iscsiadm -m session -P 0

or

iscsiadm -m session

These commands print the list of running sessions with the format:

driver [sid] ip:port,target_portal_group_tag targetname

For example:

iscsiadm -m session
