I was working on a server after there was an outage on the storage system which was a iSCSI QNAP NAS.
I did a little Google searching and found this command which worked wonderfully
iscsiadm -m session
This will give you a list of all of the devices connected via iSCSI, including the IP Address of the device you are connecting to.
Hopefully, by documenting this I will be able to remember it when I need it in the future.
