现象:
节点宕掉后,无法重启动,需拨心跳网卡几次,方能自启动,初步判定为由于HAIP莫名故障,导致一个节点无法启动CRS
1 检查网络
[grid@gmdb1 trace]$ oifcfg iflist -p -n
bond0 22.1.32.0 UNKNOWN 255.255.254.0
bond1 1.255.255.0 UNKNOWN 255.255.255.0
bond1 169.254.0.0 UNKNOWN 255.255.0.0
2 检查CRS
[root@gmdb2 tmp]# crsctl check crs
CRS-4638: Oracle High Availability Services is online
CRS-4535: Cannot communicate with Cluster Ready Services
CRS-4530: Communications failure contacting Cluster Synchronization Services daemon
CRS-4534: Cannot communicate with Event Manager
3 检查ASM和HAIP无法启动:
[root@gmdb2 tmp]# crsctl stat res -t -init
NAME TARGET STATE SERVER STATE_DETAILS Cluster Resources
ora.asm 1 ONLINE OFFLINE
ora.cluster_interconnect.haip 1 ONLINE OFFLINE
4 用mcaasttest.pl检查,并无问题:
[grid@gmdb2 mcasttest]$ perl mcasttest.pl -n gmdb2,gmdb1 -i bond0,bond1

5 检查CSSD.LOG

日志中有大量的无网络心跳的记录;
检查

发现走的HAIP,而本地的HAIP无法启动,导致CSSD启动不起来;检查CSSD的依赖关系:
[root@12crac2 ~]# crsctl stat res ora.cluster_interconnect.haip -init -f
NAME=ora.cluster_interconnect.haip

临时解决办法:
在确定心跳网络无法的情况下
禁用HAIP:
crsctl modify res ora.cluster_interconnect.haip -attr "ENABLED=0" -init
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
修改完成后,再次检查:
