Finding out which HMC your server is attached to

Find out which HMC your server is attached to (in AIX 6.1 / 7.1)

bash-3.2# lsrsrc IBM.MCP
Resource Persistent Attributes for IBM.MCP
resource 1:
        MNName           = "10.10.10.15"
        NodeID           = 4935249694248815870
        KeyToken         = "10.10.10.10"
        IPAddresses      = {"10.0.3.20","10.10.10.15","10.10.10.16","fe80::e62f:13ff:f231:6218","fe80::e62f:13ff:fe33:24b0","fe80::e62f:13ff:fe33:24b2"}
        ActivePeerDomain = ""
        NodeNameList     = {"myserver"}

In this example, we see that myserver is connected to HMC via 10.10.10.15 and 10.10.10.16.
