oracle 12c rac 在aix 7.1 上安裝需要注意的IOCP問題

安裝環境oracle 12.1.0.2 + aix 7.1

在做安裝檢查時，提示以下報錯
ERROR:

PRVE-10167 : I/O Completion Ports (IOCP) device status did not match the required value on node "tst12cdb2". [Expected = "Available"; Found = "Defined"]
PRVE-10167 : I/O Completion Ports (IOCP) device status did not match the required value on node "tst12cdb1". [Expected = "Available"; Found = "Defined"]

Check for I/O Completion Ports (IOCP) device status failed

Starting check for Berkeley Packet Filter devices /dev/bpf* existence and validation check ...

ERROR:

PRVE-0474 : Berkeley Packet Filter devices do not exist under directory /dev on nodes "tst12cdb1".

透過檢查主機IOCP狀態為Defined, 正常狀態為Available

2個節點都為Defined
tst12cdb1:/oracle/soft/gridnew/grid$ lsdev -c iocp
iocp0 Defined  I/O Completion Ports

tst12cdb2:/home/grid$ lsdev -c iocp
iocp0 Defined  I/O Completion Ports

解決方法:

  smitty iocp  改成Available即可。

如果不做這步，在裝grid時建立asm磁碟組時，會提示找不到磁碟。
