11gR2RAC更换CRS磁盘组文档
-
磁盘（pv）准备
在生产环境中，提前从存储上划分一些磁盘挂载到RAC系统的两个节点上（node1,node2).
新增加磁盘组为（hdisk14--hdisk24)
1.1磁盘使用规划

1.2检查磁盘的属性（两个节点）
lsattr -El hdisk14 | grep reserve
lsattr -El hdisk15 | grep reserve
lsattr -El hdisk16 | grep reserve
lsattr -El hdisk17 | grep reserve
lsattr -El hdisk18 | grep reserve
lsattr -El hdisk19 | grep reserve
lsattr -El hdisk20 | grep reserve
lsattr -El hdisk21 | grep reserve
lsattr -El hdisk24 | grep reserve
1.3更改磁盘的属性以支持并行操作（两个节点）
chdev -l hdisk14 -a reserve_policy=no_reserve
chdev -l hdisk15 -a reserve_policy=no_reserve
chdev -l hdisk16 -a reserve_policy=no_reserve
chdev -l hdisk17 -a reserve_policy=no_reserve
chdev -l hdisk18 -a reserve_policy=no_reserve
chdev -l hdisk19 -a reserve_policy=no_reserve
chdev -l hdisk20 -a reserve_policy=no_reserve
chdev -l hdisk21 -a reserve_policy=no_reserve
chdev -l hdisk24 -a reserve_policy=no_reserve
chdev -l hdisk14 -a reserve_lock=no
chdev -l hdisk15 -a reserve_lock=no
chdev -l hdisk16 -a reserve_lock=no
chdev -l hdisk17 -a reserve_lock=no
chdev -l hdisk18 -a reserve_lock=no
chdev -l hdisk19 -a reserve_lock=no
chdev -l hdisk20 -a reserve_lock=no
chdev -l hdisk21 -a reserve_lock=no
1.4修改字符设备的属组、权限（两个节点）
chown grid:dba /dev/rhdisk13
chown grid:dba /dev/rhdisk14
chown grid:dba /dev/rhdisk15
chown grid:dba /dev/rhdisk16
chown grid:dba /dev/rhdisk17
chown grid:dba /dev/rhdisk18
chown grid:dba /dev/rhdisk19
chown grid:dba /dev/rhdisk20
chown grid:dba /dev/rhdisk21
chown grid:dba /dev/rhdisk24
chmod 660 /dev/rhdisk13
chmod 660 /dev/rhdisk14
chmod 660 /dev/rhdisk15
chmod 660 /dev/rhdisk16
chmod 660 /dev/rhdisk17
chmod 660 /dev/rhdisk18
chmod 660 /dev/rhdisk19
chmod 660 /dev/rhdisk20
chmod 660 /dev/rhdisk21
chmod 660 /dev/rhdisk24
1.5查看磁盘的信息
ls -l /dev/rhdisk*
-
创建ASM磁盘组（节点1执行即可）
创建ASM磁盘组[示意] (grid用户)
[grid]$asmca
输入磁盘组名,采用外部冗余,然后选择磁盘.
-
数据库开启归档
3.1在一个节点上Oracle进行开启归档操作
sqlplus / as sysdba
create pfile='/home/oracle/racdbinit.ora' from spfile;
alter system set log_archive_dest_1='location=/arch1' sid='racdb1';
alter system set log_archive_dest_1='location=/arch2' sid='racdb2';
3.2停止所有数据库实例
oracle:
srvctl stop database -d racdb
3.3启动一个实例到mount状态
sqlplus / as sysdba
startup mount;
3.4开启归档日志：
alter database archivelog;
3.5停止所有数据库实例
oracle:
srvctl stop database -d racdb
3.6启动所有数据库实例
oracle:
srvctl start database -d racdb
-
数据库备份
由主机实施工程师将节点1上的/arch1使用NFS挂载到节点2的/arch2上，在节点2上使用如下mount命令挂载：
mount -v nfs -o rw,bg,hard,rsize=32768,wsize=32768,vers=3,nointr,timeo=600,proto=tcp 192.1.2.51:/arch1 /arch1
使用oracle用户登录节点2，使用rman备份数据库，备份脚本如下：
rman target /
backup database format '/arch2/rman/racdb_%U';
-
停止数据库
使用oracle用户管理所有数据库实例：
srvctl stop database -d racdb
-
更换CRS磁盘组
6.1查看当前集群的状态
[grid@node1 ~]$ crsctl stat res -t

6.2添加OCR的mirror镜像磁盘组
在节点1上使用root用户操作
cd /app/grid/11.2.0/grid/bin
/app/grid/11.2.0/grid/bin是grid用户下ORACLE_HOME的变量值。
./ocrconfig -add +TOCR
./ocrcheck 检测OCR的保存状态
过程记录如下：
# ./ocrconfig -add +TOCR
# ./ocrcheck
Status of Oracle Cluster Registry is as follows :

-
DATA磁盘组中添加磁盘
11.1查看当前DATA磁盘的故障组的情况
select name,group_number,disk_number,state,failgroup,path from v$asm_disk;
11.2向每个故障组中添加一个500G的磁盘
alter diskgroup DATA add failgroup DATA_0000 disk '/dev/rhdisk14';
alter diskgroup DATA add failgroup DATA_0001 disk '/dev/rhdisk15';
alter diskgroup DATA add failgroup DATA_0002 disk '/dev/rhdisk16';
alter diskgroup DATA add failgroup DATA_0003 disk '/dev/rhdisk17';
alter diskgroup DATA add failgroup DATA_0004 disk '/dev/rhdisk18';
11.3查看ASM实例reblance的进度
select * from v$asm_operation;
当显示如下的时候，说明reblance成功。
SQL> select * from v$asm_operation;
no rows selected
至此所有的迁移工作完成。
