Oracle11gracOCR磁盘组重命名(创建时OCR磁盘组命名错误之后的纠正方案)
参考Rename Diskgroup having OCR , Vote File , ASM SPILE (文档 ID 1335975.1)
目标：
Consider a 11.2 Grid Infrastructure with CLUSTER setup having OCR ,Vote File and ASM SPFILE on a diskgroup.
Under certain circumstances you may wish to rename that diskgroup.
"renamedg" utility can be used to rename of the diskgroup when the diskgroup is dismounted.
But since the diskgroup contains OCR and Vote File we need to use an intermediate diskgroup for storing OCR and Vote File temporarily while renaming the actual diskgroup.
更改条件说明：
-> Name of Temporary diskgroup is TEMP.
-> OCR,Voting Disks and ASM SPFILE are originally stored in a diskgroup DATA.
-> Diskgroup DATA should be renamed to CRS.
-> $ORACLE_HOME points to GRID Home.
-> Cluster is up and running in all nodes of RAC.
操作：
1 创建临时磁盘组：
Login as SYSASM using SQLPLUS into ASM instance on one node and run below commands:
sqlplus '/as sysasm'
create diskgroup TEMP normal redundancy disk '/dev/asm11' ,'/dev/asm12' ,'/dev/asm13' attribute 'compatible.rdbms'='11.2.0.0', 'compatible.asm'='11.2.0.0', 'au_size'='4M';
2 迁移
Move OCR and Vote file from DATA to :
$ORACLE_HOME/bin/bin/ocrconfig -add +TEMP
$ORACLE_HOME/bin/bin/ocrconfig -delete +DATA
$ORACLE_HOME/bin/crsctl replace votedisk +TEMP

3 迁移spfile，从DATA迁移到TEMP diskgroup上
Change ASM SPFILE location from DATA to TEMP diskgroup.
sqlplus '/as sysasm'
create pfile='/tmp/init/init' from spfile;
create spfile='+TEMP' from pfile='/tmp/init/init';
Now GPNPTOOL will get updated with new ASM SPFILE location.
That can be verified by below command :
$ORACLE_HOME/bin/gpnptool get
4 2个节点重启crs
Restart CRS on all nodes to startup CRS using new SPFILE from TEMP diskgroup
crsctl stop crs
crsctl start crs
5 卸载OLD盘(即DATA盘)
Dismount the OLD Diskgroup on all cluster nodes
Login as SYSASM using SQLPLUS into ASM instance on one node and run below commands:
sqlplus '/as sysasm'
alter diskgroup data dismount;
6 重命名OLD盘(即重命名DATA盘为CRS盘)
Rename OLD diskgroup to NEW diskgroup name
renamedg phase=both dgname=DATA newdgname=CRS verbose=true
查询磁盘信息
set line 1000
set pages 599
col path format a30
select name,path,group_number,header_status,total_mb,free_mb from v$asm_disk;
select name,state,usable_file_mb,total_mb,free_mb,required_mirror_free_mb from v$asm_diskgroup;
7 挂载CRS盘
Mount the renamed diskgroup on All the nodes
Login as SYSASM using SQLPLUS into ASM instance on one node and run below commands:
sqlplus '/as sysasm'
alter diskgroup CRS mount;
查询磁盘信息
select name,state,usable_file_mb,total_mb,free_mb,required_mirror_free_mb from v$asm_diskgroup;
8 迁移OCR和vote file到新的磁盘CRS
Move OCR and Vote file from TEMP Diskgroup to CRS Diskgroup
$ORACLE_HOME/bin/ocrconfig -add +CRS
$ORACLE_HOME/bin/ocrconfig -delete +TEMP
$ORACLE_HOME/bin/crsctl replace votedisk +CRS

9 修改spfile 路径
Change ASM SPFILE location from TEMP to CRS Diskgroup:
Login as SYSASM using SQLPLUS into ASM instance on one node and run below commands
sqlplus '/as sysasm'
create spfile='+CRS' from pfile='/tmp/init/init';
10 2个节点重启crs
Restart CRS on all nodes to startup CRS using new SPFILE from TEMP diskgroup
crsctl stop crs
crsctl start crs
11 删掉临时的TEMP磁盘组
Drop the Intermediate Diskgroup TEMP
Login as SYSASM using SQLPLUS into ASM instance on one node and run below commands::
drop diskgroup temp including contents;
NOTE: Diskgroup TEMP must be mounted in order to be able to drop it.You need to mount it (if it is not already mounted at CRS startup) and then run "drop diskgroup.."
12 删除磁盘的信息
Need to Remove the Diskgroup Resources TEMP and from Oracle Clusterware
srvctl remove diskgroup -g DATA
srvctl remove diskgroup -g TEMP
13 验证信息
Ensure ALL Cluster resources are started successfully using below sample commands
$ORACLE_HOME/bin/crsctl stat res -init -t
$ORACLE_HOME/bin/crsctl check cluster -all
$ORACLE_HOME/bin/crsctl stat res -t
