added additional ip-addresses to iscsi targets, how can we get RHEV-H to discover this?

Latest response

I just added an additional ip-address to each of my iscsi targets, and now would very much like my RHEV-H hypervisors to discover the new paths and start using them. Any ideas for how to achieve that?

I tried going to an SD, edit it, discover targets, input new ip-address, chap username = initiatorname of the "use host" value, and a password. This works for the single host that is the "use host"/SPM, but the other hypervisors doesn't pick up this. I've tried setting them in maintenance/activating, and also rebooting them.. But no new paths are discovered for any other host than the SPM.

Any ideas?

 

How I want it to look:

How it looks on non-SPM hosts:
