请问happy如何配置？我在配置时出现些问题
看到administration guide上写到：
Select this option to maintain this service IP
label/address on the same node at all times.
The service IP label/address will be kept highly
available as long as this node has an active
network interface available on this node on the
associated network. However, if the node itself
fails, or the node has no available network
interfaces, the Service IP label/address will
become unavailable.
Note, if this option is selected, and IPAT via IP
Aliases is disabled for the network of which this
interface is a part, the service IP label/address
must also be configured to the AIX 5L operating
system (in the ODM) of the node on which it is
to be maintained.
也就是说如果用service ip用节点绑定的话，必须用取代的方式，请问最后一句怎么理解。“the service IP label/address must also be configured to the AIX 5L operating system (in the ODM) of the node on which it is to be maintained.”
在AIX上必须先把这个service ip配置在另外一块网卡上，不然就选不出来？
