解决方法：
检查发现，/etc/hosts被修改：
[root@aix215 /]# cat /etc/hosts
127.0.0.1 localhost
192.168.8.215 aix215
192.168.8.216 aix216
192.168.8.209 aix215-vip
192.168.8.210 aix216-vip
10.10.10.215 aix215-priv
10.10.10.216 aix216-priv
更改为：
127.0.0.1 loopback localhost # loopback (lo0) name/address
192.168.8.215 aix215
192.168.8.216 aix216
192.168.8.209 aix215-vip
192.168.8.210 aix216-vip
10.10.10.215 aix215-priv
10.10.10.216 aix216-priv
@重新同步hacmp，问题解决！
