AIX 安装 RAC 无法发现节点(后遗症。。。）

解决无法发现节点问题后，又留下另一后遗症。。。。。。

安装CRS软件后，在第一个节点运行root.sh脚本时，出现以下错误：

[root@aix213 /]#/u01/crs_1/root.sh

WARNING: directory '/u01' is not owned by root

Checking to see if Oracle CRS stack is already configured

Setting the permissions on OCR backup directory

      [-hn hostA,hostAnum,hostB,hostBnum...]

 -o crshome     - directory CRS is installed in

 -q votedisk    - path to the CSS voting disk

 -c clustername - name of the cluster. 1-14 character string

 -l languageid  - Oracle localization language id.

 -t p1,p2,p3,p4 - Specifies TCP ports to be used by the CRS daemons

Failed to initialize Oracle Cluster Registry for cluster

解决方法：

[root@aix213 /]#cat /u01/crs_1/root.sh

#!/bin/sh

/u01/crs_1/install/rootinstall

/u01/crs_1/install/rootconfig

分析root.sh 执行的脚本：

[root@aix213 /]#cat /u01/crs_1/install/rootconfig

#!/bin/sh

#

# rootconfig.sh for Oracle CRS homes

#

#    This is run once per node during the Oracle CRS install.

#    This script does the following:

#    1) Stop if any GSDs are running from 9.x oracle homes

#    2) Initialize new OCR device or upgrade the existing OCR device

#    3) Setup OCR for running CRS stack

#    4) Copy the CRS init script to init.d for init process to start

#    5) Start the CRS stack

#    6) Configure NodeApps if CRS is up and running on all nodes

#

# NOTE: Use sample paramfile in $ORA_CRS_HOME/srvm/admin/paramfile.sample for

#       setting CRS parameters

# The following commands need to be run before Oracle Cluster Registry is

# populated.

# This is run during CRS installation and not during RAC

SILENT=false

ORA_CRS_HOME=/u01/crs_1

CRS_ORACLE_OWNER=oracle

CRS_DBA_GROUP=oinstall

CRS_VNDR_CLUSTER=true

CRS_OCR_LOCATIONS=/dev/rrac_ocr

CRS_CLUSTER_NAME=crs

CRS_HOST_NAME_LIST=

CRS_NODE_NAME_LIST=

CRS_PRIVATE_NAME_LIST=aix213-priv,,aix214-priv,

CRS_LANGUAGE_ID='AMERICAN_AMERICA.WE8ISO8859P1'

CRS_VOTING_DISKS=/dev/rrac_vote

CRS_NODELIST=aix213,aix214

发现

CRS_HOST_NAME_LIST=

CRS_NODE_NAME_LIST=

这两个环境变量后面没有赋值，应该是在初期安装CRS时，没有发现节点，通过crs配置文件生成后，而这两个变量无法自动赋值，从而导致执行脚本出错。

1、重新配置 rootconfig.sh

#!/bin/sh

#

# rootconfig.sh for Oracle CRS homes

#

#    This is run once per node during the Oracle CRS install.

#    This script does the following:

#    1) Stop if any GSDs are running from 9.x oracle homes

#    2) Initialize new OCR device or upgrade the existing OCR device

#    3) Setup OCR for running CRS stack

#    4) Copy the CRS init script to init.d for init process to start

#    5) Start the CRS stack

#    6) Configure NodeApps if CRS is up and running on all nodes

#

# NOTE: Use sample paramfile in $ORA_CRS_HOME/srvm/admin/paramfile.sample for

#       setting CRS parameters

# The following commands need to be run before Oracle Cluster Registry is

# populated.

# This is run during CRS installation and not during RAC

SILENT=false

ORA_CRS_HOME=/u01/crs_1

CRS_ORACLE_OWNER=oracle

CRS_DBA_GROUP=oinstall

CRS_VNDR_CLUSTER=true

CRS_OCR_LOCATIONS=/dev/rrac_ocr

CRS_CLUSTER_NAME=crs

CRS_HOST_NAME_LIST=aix213,1,aix214,2

CRS_NODE_NAME_LIST=aix213,1,aix214,2

CRS_PRIVATE_NAME_LIST=aix213-priv,,aix214-priv,

CRS_LANGUAGE_ID='AMERICAN_AMERICA.WE8ISO8859P1'

CRS_VOTING_DISKS=/dev/rrac_vote

CRS_NODELIST=aix213,aix214

CRS_NODEVIPS='aix213/aix213-vip/255.255.255.0/en0,aix214/aix214-vip/255.255.255.0/en0'

2、删除crs 配置信息

[root@aix213 /]#/u01/crs_1/install/rootdelete.sh

3、修改OCR、VOTE 对应raw 属性

[root@aix213 /]#ls -l /dev |grep ocr

brw-rw----    1 oracle   dba          88,  1 Feb 24 09:51 rac_ocr

crw-r-----    1    oracle   dba    88,  1 Feb 26 08:58 rrac_ocr

[root@aix213 /]#ls -l /dev |grep vote

brw-rw----    1 oracle   dba          88,  2 Feb 24 09:51 rac_vote

crw-r--r--    1    oracle   dba     88,  2 Feb 26 08:58 rrac_vote

4、清空OCR、VOTE 磁盘头信息(所有节点）

[root@aix213 /] dd  if=/dev/zero  of=/dev/rrac_ocr  bs=1024k  count=2560

[root@aix213 /] dd  if=/dev/zero  of=/dev/rrac_vote  bs=1024k  count=2560

5、重新运行root.sh

[root@aix213 /]#/u01/crs_1/root.sh

至此，问题全部解决！
