Darren,
I'm not in a position to test this right now, however I'm 99% sure that
you can use the following command on your Target server to add
additional IP addresses to your target
"lio_node --addnp=<target name> <ip address>:<port>"
<target name> is that long string that is shown in YaST in the Targets
list
(LIO supports multiple targets, so you might have multiple IP's
allocated to only 1 or a few of your target..nifty feature..)
eg "lio_node
--addnp=iqn.2014-05.suse.qa:ca790687-c098-4dcb-9f12-b0aea1c1a899
10.122.2.65:3260" will add IP address 10.122.2.65 on Port 3260 to the
Target named iqn.2014-05.suse.qa:ca790687-c098-4dcb-9f12-b0aea1c1a899
You should then be able to confirm it's working by
"lio_node --listendpoints"
Which should show you the target name, it's status, it's IP addresses
(aka Network Portals), and it's LUNS
I would be really surprised if YaST didn't co-exist with such manual
settings, but if you could test that and report back, that would be a
great help :)
Kind Regards,
- Richard
