Oracle Study之-AIX6.1构建Oracle 10gR2 RAC(3)
一、配置共享存储
[oracle@aix203 ~]$lsdev -c disk
hdisk0 Available 1S-08-00-8,0 Other SCSI Disk Drive
hdisk1 Available 1D-08-02 Other FC SCSI Disk Drive
[root@aix204 /]#lsdev -c disk
hdisk0 Available 1S-08-00-8,0 16 Bit LVD SCSI Disk Drive
hdisk1 Available 1D-08-02 Other FC SCSI Disk Drive
在aix203上创建卷组（并发卷组）
hdisk0 Available 1S-08-00-8,0 Other SCSI Disk Drive
hdisk1 Available 1D-08-02 Other FC SCSI Disk Drive
[root@aix204 /]#lsdev -c disk
hdisk0 Available 1S-08-00-8,0 16 Bit LVD SCSI Disk Drive
hdisk1 Available 1D-08-02 Other FC SCSI Disk Drive
在aix203上创建卷组（并发卷组）
[root@aix203 /]#lspv
hdisk0 000681aa6c0502a7 rootvg active
hdisk1 0008570c15134e9d rac10_vg
激活卷组，并查看卷组信息：
[root@aix203 /]#varyonvg rac10_vg
[root@aix203 /]#lsvg rac10_vg
[root@aix203 /]#lsvg rac10_vg
VOLUME GROUP: rac10_vg VG IDENTIFIER: 000681aa00004c00000001537b5134d2

创建逻辑卷：
[root@aix203 /]#cat mklv.sh
mklv -y 'rac_ocr' -t 'raw' rac10_vg 1
mklv -y 'rac_vote' -t 'raw' rac10_vg 1

mklv -y 'sysaux' -t 'raw' rac10_vg 5
mklv -y 'users' -t 'raw' rac10_vg 5
mklv -y 'undotbs1' -t 'raw' rac10_vg 5
mklv -y 'undotbs2' -t 'raw' rac10_vg 5
mklv -y 'temp' -t 'raw' rac10_vg 5
mklv -y 'control1_1' -t 'raw' rac10_vg 1
mklv -y 'control2_2' -t 'raw' rac10_vg 1
mklv -y 'control3_3' -t 'raw' rac10_vg 1
mklv -y 'spfile' -t 'raw' rac10_vg 1
mklv -y 'redo1_1' -t 'raw' rac10_vg 1

mklv -y 'redo2_2' -t 'raw' rac10_vg 1
mklv -y 'example' -t 'raw' rac10_vg 5
mklv -y 'index' -t 'raw' rac10_vg 5
查看逻辑卷信息：
[root@aix203 /]#lsvg -l rac10_vg
rac10_vg:

redo2_2 raw 1 1 1 closed/syncd N/A
example raw 5 5 1 closed/syncd N/A
index raw 5 5 1 closed/syncd N/A
在还有一个node导入卷组信息：
watermark/2/text/aHR0cDovL2Jsb2cuY3Nkbi5uZXQv/font/5a6L5L2T/fontsize/400/fill/I0JBQkFCMA==/dissolve/70/gravity/Center" alt="">
[root@aix204 /]#lsvg -l rac10_vg

index raw 5 5 1 closed/syncd N/A
二、安装配置HACMP
HACMP软件版本号6.1
须要预先安装下面软件（AIX系统盘1#）：
1） 安装hacmp

2）配置hacmp
1、配置cluster加入node
配置Cluster网络：
配置网络通讯接口：
watermark/2/text/aHR0cDovL2Jsb2cuY3Nkbi5uZXQv/font/5a6L5L2T/fontsize/400/fill/I0JBQkFCMA==/dissolve/70/gravity/Center" alt="">
改动网络属性：
在node上启动服务：
[root@aix203 /]# /usr/bin/startsrc -s clcomdES
[root@aix204 /]# /usr/bin/startsrc -s clcomdES
在两个node上配置网络參数，用于同步：
[root@aix203 /]#cat /usr/es/sbin/cluster/etc/rhosts
192.168.8.203
192.168.8.204
192.168.8.251
192.168.8.252
10.10.10.203
10.10.10.204
[root@aix203 /]#cat /usr/sbin/cluster/netmon.cf
192.168.8.203
192.168.8.204
192.168.8.251
192.168.8.252
10.10.10.203
10.10.10.204
配置hacmp同步：
配置hacmp资源组：
加入并发卷组到资源组：
watermark/2/text/aHR0cDovL2Jsb2cuY3Nkbi5uZXQv/font/5a6L5L2T/fontsize/400/fill/I0JBQkFCMA==/dissolve/70/gravity/Center" alt="">
再次同步hacmp配置！
watermark/2/text/aHR0cDovL2Jsb2cuY3Nkbi5uZXQv/font/5a6L5L2T/fontsize/400/fill/I0JBQkFCMA==/dissolve/70/gravity/Center" alt="">
watermark/2/text/aHR0cDovL2Jsb2cuY3Nkbi5uZXQv/font/5a6L5L2T/fontsize/400/fill/I0JBQkFCMA==/dissolve/70/gravity/Center" alt="">
启动hacmp服务：
watermark/2/text/aHR0cDovL2Jsb2cuY3Nkbi5uZXQv/font/5a6L5L2T/fontsize/400/fill/I0JBQkFCMA==/dissolve/70/gravity/Center" alt="">
查看hacmp服务：
[root@aix203 soft1]#lssrc -a |grep cl
clcomd caa 5046426 active
clcomdES clcomdES 5767410 active
clstrmgrES cluster 3801194 active
gsclvmd 6488150 active
clconfd caa inoperative
nimsh nimclient inoperative
clcomd caa 5046426 active
clcomdES clcomdES 5767410 active
clstrmgrES cluster 3801194 active
gsclvmd 6488150 active
clconfd caa inoperative
nimsh nimclient inoperative
三、查看卷组并发状态
[root@aix203 soft1]#lspv
hdisk0 000681aa6c0502a7 rootvg active
hdisk1 0008570c15134e9d rac10_vg concurrent
[root@aix203 soft1]#lsvg -l rac10_vg
hdisk0 000681aa6c0502a7 rootvg active
hdisk1 0008570c15134e9d rac10_vg concurrent
[root@aix203 soft1]#lsvg -l rac10_vg
rac10_vg:
LV NAME TYPE LPs PPs PVs LV STATE MOUNT POINT
rac_ocr raw 1 1 1 closed/syncd N/A
rac_vote raw 1 1 1 closed/syncd N/A
system raw 10 10 1 closed/syncd N/A
sysaux raw 5 5 1 closed/syncd N/A
users raw 5 5 1 closed/syncd N/A
undotbs1 raw 5 5 1 closed/syncd N/A
undotbs2 raw 5 5 1 closed/syncd N/A
temp raw 5 5 1 closed/syncd N/A
control1_1 raw 1 1 1 closed/syncd N/A
control2_2 raw 1 1 1 closed/syncd N/A
control3_3 raw 1 1 1 closed/syncd N/A
spfile raw 1 1 1 closed/syncd N/A
redo1_1 raw 1 1 1 closed/syncd N/A
redo1_2 raw 1 1 1 closed/syncd N/A
redo2_1 raw 1 1 1 closed/syncd N/A
redo2_2 raw 1 1 1 closed/syncd N/A
example raw 5 5 1 closed/syncd N/A
index raw 5 5 1 closed/syncd N/A
[root@aix204 /]#lspv
hdisk0 0003504af4d8495b rootvg active
hdisk1 0008570c15134e9d rac10_vg concurrent
------- 卷组处于并发状态后。hacmp配置成功 ！
