[SOLVED] how can i identify NICs in use for iSCSI multipath

[hotwired007]

I have 5 nodes, each node has 6 NICs, 2 are bonded for proxmox traffic (Active/Backup) 4 are used for dedicatied iSCSI traffic.

I ahve an error showing a disconnect in all 5 Nodes @ 6.22am, i need to find out which NIC on each server is in use for the following iSCSI connections:

a) 8:0:0:0 (SDC) & 8:0:0:1 (SDE)
b) 7:0:0:0 (SDB) & 7:0:0:1 (SDD)
c) 5:0:0:0 (SDC) & 5:0:0:1 (SDG)
d) 12:0:0:0 (SDM) & 12:0:0:1 (SDP)
e) 5:0:0:0 (SDE) & 5:0:0:1 (SDG)

any suggestions on how to show which NICs these are from?

iscsiadm -m sessions shows this:
