Note:  The  Approaching out of compliance  status is a normal status in the Enterprise  Pool, and it is useful when you need extra resources temporarily. The PowerHA  SystemMirror RG takeover scenario is one of the cases. The  hacmp.out  log file records the process of the RG offlining, as shown in Example 6-20. During the release process, the de-allocation order is EPCoD and then the local server’s free  pool. Because EPCoD is shared between different servers, the standby node on other  servers always needs this resource to bring the RG online in a takeover scenario. In this case, the RG online on standby node does not need to wait for the DLPAR to complete  on the primary node because it is an asynchronous process. In this process, PowerHA  SystemMirror acquires a corresponding resource for the onlining RG. Note:  Before acquiring the process start, the 2C and 30 GB resources were available in  the Enterprise Pool, so this kind of resource can also be used by standby node. Chapter 6.
