在aix上安装10g crs"SPECIFY CLUSTER CONFIGURATION"界面没有列出节点,如下图所示并没有列出要安装rac的节点信息。下面列出了三种方法，因为我装的rac使用的是asm并不使用hacmp（而这个系统被集成商提前装好了hacmp的），所以我写在hacmp即可：

# smitty install_removeà勾选所有的含有cluster包# lssrc –g cluster 检验是否卸载干净，然后可以看到节点信息。

下面是参考的三种解决方法（方法2没有验证过）

1)如果用ASM，不用concurrent vg可以删除hacmp的包来解决。
2)或者使用use cluster configuration file来添加节点，毕竟有了crs之后hacmp对oracle没有作用
3)第三种方法就是这个文档，找出真正原因

IBM AIX Based Systems (64-bit)

HACMP

Symptoms

Installing the Oracle clusterware on top of HACMP clusterware in AIX.

In the "Specify Cluster Configuration" screen during Oracle Clusterware installation,no nodes appear in the list and the Add button icon is disabled. When HACMP is installed, the node selection screen should be predefined with the nodes of the HACMP cluster and be updatable for the network setup (vip, etc..)

cd /tmp/OraInstall2008-04-22_01-45-01PM/oui/bin/lsnodes also failing with following error.

# ./lsnodes
exec(): 0509-036 Cannot load program /tmp/OraInstall2008-04-22_01-45-01PM/oui/bin/lsnodes.bin because of the following errors:
0509-150 Dependent module libskgxn2.a(shr_skgxn2.o) could not be loaded.
0509-022 Cannot load module libskgxn2.a(shr_skgxn2.o).
0509-026 System error: A file or directory in the path name does not exist.

Cause

HACMP clusterware is already installed and configured properly.while installing the Oracle clusterware ,it does not detect the vendor clusterware present.

Run the rootpre.sh script. to check the HACMP present or not.but the output shows.

Checking if group services should be configured....
ODMDIR=/etc/objrepos, isSP= 0, isHACMP= 0
Nothing to configure.

This is not expected output if the HACMP is present.


The rootpre.sh script. tries to determine if HACMP is on with the following check:

isHACMP=`${ODMGET} -q name=cluster.es.clvm.rte lpp 2>/dev/null | wc -l`

When this check fails, the "/opt/ORCLcluster" directory never gets created since, there's no cluster detected. So when the installer tries to run lsnodes, it's missing lib files from the "/opt/ORCLcluster" directory.

Solution

Install the missing fileset ie cluster.es.clvm.rte lpp on all the nodes.

Run the below command to check the fileset is installed

lslpp -l cluster.es.clvm.rte

and re-run the rootpre.sh to check the HACMP is detecting

Oracle provides Cluster Verification Utility (CVU) to perform. system checks in preparation for installation, patch updates, or other system changes.

This will ensure that you have completed the required system configuration and preinstallation steps so that your installation, update, or patch operation completes successfully

Run the cluvfy to check all prerequisites are configured properly

./runcluvfy.sh stage -pre crsinst -n , -verbose

Make sure all OS patchsets are installed for HACMP to support Oracle Clusterware.

Please go through the below Note for Prerequisites and ceritification details for Installing Oracle clusterware on IBM AIX systems.

Note 282036.1 Minimum Software Versions and Patches Required to Support Oracle Products on IBM pSeries

For HACMP 5.4,you need to download the below patch before Installing the CRS.

i) Download the Patch 6718715
