在aix上安裝10g crs"SPECIFY CLUSTER CONFIGURATION"介面沒有列出節點

在aix上安裝10g crs"SPECIFY CLUSTER CONFIGURATION"介面沒有列出節點,如下圖所示並沒有列出要安裝rac的節點資訊。下面列出了三種方法，因為我裝的rac使用的是asm並不使用hacmp（而這個系統被整合商提前裝好了hacmp的），所以我寫在hacmp即可：

# smitty install_removeà勾選所有的含有cluster包# lssrc –g cluster 檢驗是否解除安裝乾淨，然後可以看到節點資訊。

下面是參考的三種解決方法（方法2沒有驗證過）

1)如果用ASM，不用concurrent vg可以刪除hacmp的包來解決。
2)或者使用use cluster configuration file來新增節點，畢竟有了crs之後hacmp對oracle沒有作用
3)第三種方法就是這個文件，找出真正原因

CANNOT ADD NODE DETAILS IN "SPECIFY CLUSTER CONFIGURATION" OUI SCREEN [ID 754906.1]

Applies to:

Oracle Server - Enterprise Edition - Version: 10.1 to 11.1
IBM AIX Based Systems (64-bit)
CRS
RAC
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.

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