小弟最近在用两个LPAR练习搭建HACMP环境，由于不知道如何在虚拟环境上模拟串口心跳，就选择了用磁盘做心跳的方式。
搭建完后到执行“Extended Verification and Synchronization” 验证时，最后结果是OK的，但是发现有以下报警：
WARNING: sea002: Read on disk /dev/hdisk4 failed.
Check cables and connections.
A reserve may be set on that disk by another node.
WARNING: sea003: Read on disk /dev/hdisk4 failed.
Check cables and connections.
A reserve may be set on that disk by another node.
想请问各位大大，出现这种警告是配置得有问题还是一个HA的小BUG？
注：dhb_read命令检测没问题
