I Have exact the same problem. I'm trying to add a third node (it was
delivered later) and it can see the LUNs, but it says that it contains
no partitions. Strange, because the first two nodes are running on it

What is also strange is that when viewing the storage subsystems in
the Secure Path agent is that the first two nodes see a subsystem
identified by an identical number: 500805f300165600

The third node sees the identifier as: 0000000000000000

So I'm not so sure it's a SAN issue, because the third node can see
the LUNs

Any suggestions on this?
