Example 1: The configuration file content is as follows:

parameters:
 ALUA:
 "*":
 MULTIPATHTYPE: 1
 FAILOVERMODE: 3
 SPECIALMODETYPE: 0
 PATHTYPE: 0
 node1:
 MULTIPATHTYPE: 1
 FAILOVERMODE: 3
 SPECIALMODETYPE: 0
 PATHTYPE: 1

If the host name is node1, both of the preceding ALUA configuration sections can be used to configure initiators. According to the configuration policy rules in Configuring ALUA Parameters for a Huawei Enterprise Storage Backend , the priority of the second configuration section (where HostName is node1) is higher than that of the first configuration section (where HostName is *).

Example 1: The configuration file content is as follows:

parameters:
 ALUA:
 "*":
 switchoverMode: Enable_alua
 pathType: optimal_path
 node1:
 switchoverMode: Enable_alua
 pathType: non_optimal_path

If the host name is node1, both of the preceding ALUA configuration sections can be used to configure initiators. According to the configuration policy rules in Configuring ALUA Parameters for a Distributed Storage Backend , the priority of the second configuration section (where HostName is node1) is higher than that of the first configuration section (where HostName is *).
