Discovering Assets on Multiple Subnets

I saw this question recently, about making discovery work:

"I am attempting to discover a group of ILOMs which seem to be on a different subnet than their hosts. When I try to discover the ILOMs, Ops Center can't find them. Is it a requirement that the ILOM and its host should be on the same subnet?"

The short answer is no, related assets don't have to be on the same subnet for you to discover them. The correlation between related assets doesn't depend on them being on the same subnet.

What's likely going on, if you're running into similar issues, is that the subnet where you're trying to discover systems needs to be associated with a Proxy Controller that can reach it. You can go here to see how to associate a network with a Proxy Controller. Once the network is associated with a Proxy Controller, you should be able to discover and manage assets on it.

Hi Owen,

i face this issue, all my asset in different subnet.
ex. in same machine, ILOM/XSCF (SP) in segment 10.2.246.0/24 and OS in segment 10.2.115.0/24.

i have 2 proxies(PCs). co-located PC-A and PC-B.
net 10.2.246.0/24 is part of PC-A.
net 10.2.115.0/24 is part of PC-B

is it okay if asset SP managed by PC-A whereas asset OS managed by PC-B ? ....
is there any issue in OS provisioning ?

should i associate one of them in same PC ? ...
if yes, which segment/net should we associate ? ... 10.2.246.0/24 or 10.2.115.0/24 ? ..

any suggestion ?

thanks,

Wong

Wong,

It is fine for two related assets, such as an SP and an OS, to be on separate subnets and be managed by separate Proxy Controllers.

I don't think that there should be any problem during OS provisioning, either; as long as you have at least one Proxy Controller that's associated with the new OS's subnet, Ops Center should be able to manage it without any problem.

What to do if you cannot see any networks in that associate networks pane per link : http://docs.oracle.com/cd/E27363_01/doc.121/e25143/infrastructure.htm#OPCAG382 section 2.11.1

Guest,

The PC is automatically associated with the network it's on. Is the network already listed in the PC's configuration tab? If not, is it reachable from the PC?
