私网网卡掩码对集群启动得影响

当集群启动后，私网网卡会挂载一个169.254开头的虚拟IP。这是ora.cluster_interconnect.haip 服务启动后产生的。若是网卡的掩码改变会影响集群启动吗？下面是用19c的环境来测试一下。
首先看下一下集群中记录的网卡配置

[grid@node1 ~]$ oifcfg getif
ens33  192.168.233.0  global  public
ens34  10.10.10.0  global  cluster_interconnect,asm

私网网卡的 subnet是 10.10.10.0。

3: ens34: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc pfifo_fast state UP group default qlen 1000
    link/ether 00:0c:29:f6:ec:c6 brd ff:ff:ff:ff:ff:ff
    inet 10.10.10.10/24 brd 10.10.10.255 scope global noprefixroute ens34
       valid_lft forever preferred_lft forever
    inet 169.254.8.117/19 brd 169.254.31.255 scope global ens34:1
       valid_lft forever preferred_lft forever
    inet6 fe80::6d44:9f70:691d:130e/64 scope link noprefixroute
       valid_lft forever preferred_lft forever

当前私网网卡的掩码是 24
若将掩码改成16，集群能正常启动吗？修改以后，重新启动集群

3: ens34: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc pfifo_fast state UP group default qlen 1000
    link/ether 00:0c:29:f6:ec:c6 brd ff:ff:ff:ff:ff:ff
    inet 10.10.10.10/16 brd 10.10.255.255 scope global noprefixroute ens34
       valid_lft forever preferred_lft forever
    inet6 fe80::6d44:9f70:691d:130e/64 scope link noprefixroute
       valid_lft forever preferred_lft forever

集群服务卡在了 ora.cluster_interconnect.haip 启动上，且在日志种可以发现

节点上的 ens34 没有配置 10.10.10.0的子网，当前可用的网卡是 ens34 子网是10.10.0.0
若是将掩码改成 23呢

3: ens34: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc pfifo_fast state UP group default qlen 1000
    link/ether 00:0c:29:f6:ec:c6 brd ff:ff:ff:ff:ff:ff

ora.crf
      1        ONLINE  ONLINE       node1                    STABLE

此时ora.cluster_interconnect.haip 就可以正常启动了。
这是因为 10.10.10.10/24 跟 10.10.10.10/23 属于同一个subnet 10.10.10.0

当吧掩码改成 22时

3: ens34: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc pfifo_fast state UP group default qlen 1000
    link/ether 00:0c:29:f6:ec:c6 brd ff:ff:ff:ff:ff:ff

因为掩码位22时 subnet为10.10.8.0 所以ora.cluster_interconnect.haip 不能正常启动
