yes that did it, the syntax you gace was "nearly correct" which is amzingly
good if from memory.
correct syntax:
lio_node --addnp=TARGET_IQN TPGT IP:PORT <= in my case the TPGT value=1 so
my actual used syntax was:
lio_node --addnp
vmdisk01.iqn.2014-05.sles12source.testlab.akurit.com.au:610ebff1-2e78-4274-b4ce-e85077f6ff4b
1 192.168.100.200:3260
lio_node --addnp
vmdisk01.iqn.2014-05.sles12source.testlab.akurit.com.au:610ebff1-2e78-4274-b4ce-e85077f6ff4b
1 192.168.200.200:3260
which produced (edited to conserve space):
io_node --listendpoints
\------> vmdisk01.iqn.2014-05.sles12source.testlab.akurit.com.au:610
ebff1-2e78-4274-b4ce-e85077f6ff4b
\-------> tpgt_1 TargetAlias: LIO Target
TPG Status: ENABLED
TPG Network Portals:
\-------> 192.168.200.200:3260
\-------> 192.168.100.200:3260
\-------> 192.168.0.200:3260
TPG Logical Units:
\-------> lun_0/dev_DATA_VMDISK01 ->
target/core/iblock_0/dev_DATA_VMDISK01
Thanks again...
BTW this is not "intuitive" or "easily discovered" so will need to be
clearly documented somewhere before release to the "great unwashed masses"
:-)
Regards
Darren
