因为 “hdisk0” 通常包含 “rootvg” 卷组，一个受管理系统上的所有 LPAR 的 “hdisk0” 的主通信路径都通过同一个 VIO 服务器是不合适的。

Since "hdisk0" usually contains the "rootvg" volume group, it is NOT desirable to have the primary path of "hdisk0" for all LPAR's on a managed system going through the same VIO server.

等到连接恢复时，就可以重新打开HADR，而备用系统将与主系统通信，并执行“catch - up”操作，直到它返回到同步状态。

Once connectivity is restored, you can turn HADR back on and the standby will communicate with the primary and perform "catch-up" operations until it returns to a synchronized state.

尽管从电池系统到主CAN总线有一个接口也许是可取的，但在电池组内部，SPI或I2C通信是有利的。

While an interface from the battery system to the main can bus may be desirable, SPI or I2C communications can be advantageous within the battery pack.
