haip一般出现与私网网卡上，在安装rac的过程中，通过算法生成一个169.254网段的ip地址，然后通过arp方式向局域网内发送广播，判断当局域网内无此IP时，就会正式分配此IP给rac。此haip地址是分配之后无法更改的，及时修改了私网IP地址，此IP都不会发生变化。

2、haip的子网掩码是多少，能容纳多少个主机
p1p2:1 Link encap:Ethernet HWaddr B0:26:28:6D:43:C1 inet addr:169.254.251.235 Bcast:169.254.255.255 Mask:255.255.128.0 UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1
从以上信息可以看到haip的子网掩码是255.255.128.0，即网络位是17位（169.254.251.235/17），可容纳的主机数是2^15，可用的主机数是2^15-2。
官方建议：
1.Run "crsctl stop crs" on all nodes to stop CRS stack.2. 关闭HAIP
2. On one node, run the following commands:
$CRS_HOME/bin/crsctl start crs -excl -nocrs
$CRS_HOME/bin/crsctl stop res ora.asm -init
$CRS_HOME/bin/crsctl modify res ora.cluster_interconnect.haip -attr "ENABLED=0" -init
$CRS_HOME/bin/crsctl modify res ora.asm -attr "START_DEPENDENCIES='hard(ora.cssd,ora.ctssd)pullup(ora.cssd,ora.ctssd)weak(ora.drivers.acfs)',STOP_DEPENDENCIES='hard(intermediate:ora.cssd)'" -init
$CRS_HOME/bin/crsctl stop crs4. 进一步测试
3. Repeat Step(2) on other nodes.
4. Run "crsctl start crs" on all nodes to restart CRS stack.
