How can I connect to iSCSI target from Linux console?

First you need to discover targets under portal IP address:

iscsiadm --mode discovery --type sendtargets --portal 192.168.1.10 # Replace 192.168.1.10 with Your portal IP address

Login, must use a node record id found by the discovery:

iscsiadm --mode node --targetname iqn.2001-05.com.doe:test --portal 192.168.1.1:3260 --login 

Logout:

iscsiadm --mode node --targetname iqn.2001-05.com.doe:test --portal 192.168.1.1:3260 --logout 

List node records:

iscsiadm --mode node 

Display all data for a given node record:

iscsiadm --mode node --targetname iqn.2001-05.com.doe:test --portal 192.168.1.1:3260
