]Cause
The problem is caused by netmask mismatch between ifconfig and OCR config.
In OCR:
node01_OCRDUMP---------
[SYSTEM.CRSD.RESOURCES.ora!net1!network.CONFIG]
USR_ORA_IF=bond0~USR_ORA_NETMASK=255.255.255.192~USR_ORA_SUBNET=192.168.1.0~VERSION=11.2.0.1.0
# ifconfig
bond0 Link encap:Ethernet HWaddr 00:00:49:6F:E3:A5
inet addr:192.168.1.7 Bcast:192.168.1.127 Mask:255.255.255.128
OCR shows netmask of 255.255.255.192 and ifconfig shows netmask of 255.255.255.128. Due to this mismatch, the
ora.net1.network resource cannot be started.
Solution1. If OCR entry is correct, modify NETMASK setting for bond0 interface
in /etc/sysconfig/network-scripts/ifcfg-bond0, change NETMASK value from 255.255.255.128 to 255.255.255.192.
2. If OCR entry needs to be modified to match the OS setting, then use srvctl modify nodeapps command as root
user. For example:
# srvctl modify nodeapps -n node01 -A /255.255.255.128/bond0
For 11.2.0.2 onward, one can modify the network resource directly:
# srvctl modify network -k 1 -S
Once network resource is modified, node VIP netmask will be changed automatically.
3. After they match, network resource should be able to start.
$ ./srvctl start nodeapps -n node01
本案是由于集群的public ip、vip地址的netmask（子网掩码）被人（小机工程师）擅自修改成255.255.240.0，原来是255.255.248.0，导致监听，ons集群资源无法启动.
依据metalink，使用root用户进行以下修改：
./srvctl modify nodeapps -n rac1 -A 172.16.41.21/255.255.248.0/en9 ###public ip
./srvctl modify nodeapps -n rac2 -A 172.16.41.22/255.255.248.0/en9 ###public ip
./srvctl modify nodeapps -n rac1 -A 172.16.41.23/255.255.248.0/en9 ###vip
./srvctl modify nodeapps -n rac2 -A 172.16.41.24/255.255.248.0/en9 ###vip
然后，重启集群即可.
