可能是由 Bug:6608472 引起的， 但是MOS上描述该bug 在10.2.0.4 已修复

racgvip日志中只有 Invalid parameters, or failed to bring up VIP  的信息

如果要进一步确认， 需要对vip resource做debug :

crsctl debug log res "ora.power740a.vip:5"
crsctl debug log res "ora.power740b.vip:5"
                 
之后手动启动  vip 资源

crs_start ora.power740a.vip
crs_start ora.power740b.vip
                                 
等待 vip OFFLINE ， 上传 $ORA_CRS_HOME/log/racg下的所有日志
还原                                 
crsctl debug log res "ora.power740a.vip:0"
crsctl debug log res "ora.power740b.vip:0"

PING power740a: (10.18.1.91): 56 data bytes
64 bytes from 10.18.1.91: icmp_seq=0 ttl=255 time=0 ms

public interface is en12

en12 Device Type: EtherChannel


ODM Finding:

1. RAC on AIX: With Virtual Interfaces Racgvip Fails Even Though Public Interface is Up [ID 567286.1]
   
2. 
   
3. Applies to:
   
4. Oracle Server - Enterprise Edition - Version: 10.2.0.3 and later   [Release: 10.2 and later ]
   
5. IBM AIX on POWER Systems (64-bit)
   
6. IBM AIX Based Systems (64-bit)
   
7. Symptoms
   
8. 
   
9. If the Etherchannel and VLAN devices are used for the public network, racgvip script may fail and cause the VIP to offline as a result.   
   
10. Cause
    
11. 
    
12. Currently, the racgvip script issues the following command to check if the public network is up:
    
13. 
    
14. 
    
15. '$ENTSTAT -d $_IF | $GREP -iEq '.*lan.*state.*:.*operational.*
    
16. |.*link.*status.*:.*up.*' "
    
17. 
    
18. 
    
19. 
    
20. However on some of the new AIX network devices, the output from the following command is different, so the above grep check on the entstat output fails:
    
21. 
    
22. 
    
23. entstat -d <interface name>
    
24. 
    
25. 
    
26. Bug:6608472 addresses this problem.
    
27. 
    
28. 
    
29. The new fix is in 10.2.0.3 patch 6851901 (MLR #16).
    
30. 
    
31. Although the bug 6608472 does not say the fix is in the patch 6851901, this patch (6851901) has the new racgvip that now issues the following to check the health of the public network:
    
32. 
    
33. $ENTSTAT -d $_IF | $GREP -iEq '.*lan.*state.*:.*operational.*|.*link.*status.*:.*up.*|.*port.*operational.*state.*:.*up.*'
    
34. 
    
35. The fix for the bug 6608472 is also included in 10.2.0.4
    
36. Solution
    
37. To resolve this issue, apply patch 6851901.
    
38. 
    
39. Again, this patch provides the new racgvip script that can handle the new / current AIX interface types.
    
40. 
    
41. The fix for the bug 6608472 is also in 10.2.0.4, so upgrading the CRS to 10.2.0.4 will resolve the problem produced by the bug 6608472.

If the Etherchannel and VLAN devices are used for the public network, racgvip script may fail and cause the VIP to offline as a result.
