Hi All, Thank you all for your comments. I have originally wondered if it was possible to share the target to the host itself and that was answered as a yes. that lead me to "I must be doing something wrong". It turns out it was 2 things.
1st the way I created my LUNs was wrong and 2nd forgot about the ACL. After I reviewed those 2 things, everything is working as expected. Just had to re-read the examples i was working from to better understand the issue. Original way: asmdatadisk4 is a udev raw device /iscsi> create iqn.2021-04.local.poc-ora-cluster1:asmdatadisk4 cd iqn.2021-04.local.poc-ora-cluster1:asmdatadisk4/tpg1/ luns/ create/backstores/block/asmdatadisk4 acls/ create iqn.2021-04.local.poc-ora-cluster1:asmdatadisk4 set attribute authentication=0 set attribute generate_node_acls=1 set attribute demo_mode_write_protect=0 cd ../.. Working way: cd /backstores/block create name=LUN_0 dev=/dev/sdf create name=LUN_1 dev=/dev/sdd create name=LUN_2 dev=/dev/sde cd /iscsi create ls cd iqn.2003-01.org.linux-iscsi.poc-ora-cluster1.x8664:sn.d67e31a1c6f9/tpg1/luns create /backstores/block/LUN_0 create /backstores/block/LUN_1 create /backstores/block/LUN_2 and of course this line for ACL cd /iscsi/iqn.2003-01.org.linux-iscsi.poc-ora-cluster1.x8664:sn.d67e31a1c6f9/tpg1 set attribute authentication=0 demo_mode_write_protect=0 generate_node_acls=1 cache_dynamic_acls=1 Apologies for not replying sooner, was working on getting this demo going.
