Oracle ocr磁盘更换

一. 创建新的OCR磁盘组

（在一个节点执行就可以）

[root@rac1 rules.d]# su - grid
[grid@rac1 ~]$ asmca

1. 创建新的OCR磁盘组：

2. 查看两个节点是否添加了新的OCR磁盘组：

节点1：

SQL> set linesize 1000SQL> select name, TOTAL_MB, FREE_MB, state, type, COMPATIBILITY from v$asm_diskgroup;
NAME         TOTAL_MB FREE_MB STATE TYPE COMPATIBILITY------------------------------ ---------- ---------- ----------- ------ ------------------------------------------------------------ARCH             4096 3302 MOUNTED EXTERN 11.2.0.0.0DATA            10240 8130 MOUNTED EXTERN 11.2.0.0.0NEWOCR             9216 9057 MOUNTED NORMAL 11.2.0.0.0OCR                  9216 8290 MOUNTED NORMAL 11.2.

节点2：

SQL> set linesize 1000SQL> select name, TOTAL_MB, FREE_MB, state, type, COMPATIBILITY from v$asm_diskgroup;
NAME         TOTAL_MB    FREE_MB STATE   TYPE  COMPATIBILITY------------------------------ ---------- ---------- ----------- ------ ------------------------------------------------------------ARCH             4096  3302 MOUNTED   EXTERN 11.2.0.0.0DATA            10240  8130 MOUNTED   EXTERN 11.2.0.0.0NEWOCR              0     0 DISMOUNTED        0.0.0.0.0OCR                 9216  8290 MOUNTED   NORMAL 11.2.0.0.0

3. 发现节点2，需要手动mount新加的ASM磁盘组：

[root@rac2 ~]# su - grid[grid@rac2 ~]$ sqlplus / as sysasm
SQL*Plus: Release 11.2.0.4.0 Production on Thu Apr 6 07:36:04 2017
Copyright (c) 1982, 2013, Oracle.  All rights reserved.

Connected to:Oracle Database 11g Enterprise Edition Release 11.2.0.4.0 - 64bit ProductionWith the Real Application Clusters and Automatic Storage Management options
SQL> SQL> alter diskgroup NEWOCR mount;
Diskgroup altered.

4. 再次查看节点2新加的OCR磁盘组：

SQL> set linesize 1000SQL> select name, TOTAL_MB, FREE_MB, state, type, COMPATIBILITY from v$asm_diskgroup;
NAME         TOTAL_MB    FREE_MB STATE   TYPE  COMPATIBILITY------------------------------ ---------- ---------- ----------- ------ ------------------------------------------------------------ARCH             4096  3302 MOUNTED   EXTERN 11.2.0.0.0DATA            10240  8130 MOUNTED   EXTERN 11.2.0.0.0NEWOCR             9216  8931 MOUNTED   NORMAL 11.2.0.0.0OCR                 9216  8290 MOUNTED   NORMAL 11.2.0.0.0

二. 添加OCR信息到新的OCR磁盘组

（迁移OCR磁盘组）（一个节点上执行）

[root@rac1 ~]# su - grid
[grid@rac1 ~]$ su rootPassword: 
[root@rac1 grid]# ocrconfig -add +NEWOCR
[root@rac1 grid]# ocrcheck -configOracle Cluster Registry configuration is :   Device/File Name         :       +OCR   Device/File Name         :    +NEWOCR
[root@rac1 grid]# more /etc/oracle/ocr.loc#Device/file  getting replaced by device +NEWOCR ocrconfig_loc=+OCRocrmirrorconfig_loc=+NEWOCRlocal_only=false
[root@rac1 grid]# ocrcheck && crsctl query css votedisk   -- 检查、查看voting diskStatus of Oracle Cluster Registry is as follows :   Version                  :          3   Total space (kbytes)     :     262120   Used space (kbytes)      :       3464   Available space (kbytes) :     258656   ID                       : 1896437032   Device/File Name         :       +OCR                                    Device/File integrity check succeeded   Device/File Name         :    +NEWOCR                                    Device/File integrity check succeeded
                                    Device/File not configured
                                    Device/File not configured
                                    Device/File not configured
   Cluster registry integrity check succeeded
   Logical corruption check succeeded
##  STATE    File Universal Id                File Name Disk group--  -----    -----------------                --------- --------- 1. ONLINE   a96d9ab34e494f8fbf921c97da8e6580 (/dev/raw/raw1) [OCR] 2. ONLINE   29b205061cc44f8abf86d791f6cf8db0 (/dev/raw/raw2) [OCR] 3. ONLINE   75fb74dbdd8b4f74bf22870f7d7b59bd (/dev/raw/raw3) [OCR]Located 3 voting disk(s).

三. 迁移VOTE DISK到新建的ASM磁盘组OCR上

1. 查询当前使用的OCR磁盘组：

SQL> set linesize 1000SQL> select GROUP_NUMBER,NAME,STATE,type,TOTAL_MB,free_mb,VOTING_FILES,COMPATIBILITY from v$asm_diskgroup;
GROUP_NUMBER NAME          STATE  TYPE   TOTAL_MB    FREE_MB V COMPATIBILITY------------ ------------------------------ ----------- ------ ---------- ---------- - ------------------------------------------------------------     1 ARCH            MOUNTED    EXTERN       4096  3302 N 11.2.0.0.0     2 DATA            MOUNTED   EXTERN      10240  8130 N 11.2.0.0.0     3 NEWOCR            MOUNTED  NORMAL       9216  8388 N 11.2.0.0.0     4 OCR                MOUNTED  NORMAL       9216  8290 Y 11.2.0.0.0

2. 替换为新添加的OCR：

[root@rac1 ~]# su - grid
[grid@rac1 ~]$ su rootPassword: [root@rac1 grid]# crsctl replace votedisk +NEWOCRSuccessful addition of voting disk 9c4a22a517044f4dbf6a8595b0f507f9.Successful addition of voting disk 372d1b3550844f9cbffaf00b6a2dbe96.Successful addition of voting disk 08ab4466be804f48bfea02f300de046a.Successful deletion of voting disk a96d9ab34e494f8fbf921c97da8e6580.Successful deletion of voting disk 29b205061cc44f8abf86d791f6cf8db0.Successful deletion of voting disk 75fb74dbdd8b4f74bf22870f7d7b59bd.Successfully replaced voting disk group with +NEWOCR.CRS-4266: Voting file(s) successfully replaced

3. 再次查询使用的OCR磁盘组：

SQL> set linesize 1000SQL> select GROUP_NUMBER,NAME,STATE,type,TOTAL_MB,free_mb,VOTING_FILES,COMPATIBILITY from v$asm_diskgroup;
GROUP_NUMBER NAME          STATE  TYPE   TOTAL_MB    FREE_MB V COMPATIBILITY------------ ------------------------------ ----------- ------ ---------- ---------- - ------------------------------------------------------------     1 ARCH            MOUNTED  EXTERN       4096  3302 N 11.2.0.0.0     2 DATA            MOUNTED  EXTERN      10240  8120 N 11.2.0.0.0     3 NEWOCR               MOUNTED  NORMAL       9216  8292 Y 11.2.0.0.0     4 OCR                MOUNTED  NORMAL       9216  8386 N 11.2.0.0.0

4. 发现voting file已经在NEWOCR上，然后在两个节点的root下查询：

节点1：

[root@rac1 ~]# su - grid
[grid@rac1 ~]$ su rootPassword:
[root@rac1 grid]# ocrcheck && crsctl query css votediskStatus of Oracle Cluster Registry is as follows :   Version                  :          3   Total space (kbytes)     :     262120   Used space (kbytes)      :       3464   Available space (kbytes) :     258656   ID                       : 1896437032   Device/File Name         :       +OCR                                    Device/File integrity check succeeded   Device/File Name         :    +NEWOCR                                    Device/File integrity check succeeded
                                    Device/File not configured
                                    Device/File not configured
                                    Device/File not configured
   Cluster registry integrity check succeeded
   Logical corruption check succeeded
##  STATE    File Universal Id                File Name Disk group--  -----    -----------------                --------- --------- 1.

节点2：

[root@rac2 ~]# su - grid
[grid@rac2 ~]$ su rootPassword: 
[root@rac2 grid]# ocrcheck && crsctl query css votediskStatus of Oracle Cluster Registry is as follows :   Version                  :          3   Total space (kbytes)     :     262120   Used space (kbytes)      :       3464   Available space (kbytes) :     258656   ID                       : 1896437032   Device/File Name         :       +OCR                                    Device/File integrity check succeeded   Device/File Name         :    +NEWOCR                                    Device/File integrity check succeeded
                                    Device/File not configured
                                    Device/File not configured
                                    Device/File not configured
   Cluster registry integrity check succeeded
   Logical corruption check succeeded

ONLINE   08ab4466be804f48bfea02f300de046a (/dev/raw/raw9) [NEWOCR]Located 3 voting disk(s).

四. 创建ASM实例spfile到新建的OCR ASM磁盘组上

在一个节点以grid用户登录ASM实例执行：

[root@rac1 ~]# su - grid
[grid@rac1 ~]$ sqlplus / as sysasm
SQL*Plus: Release 11.2.0.4.0 Production on Fri Apr 7 19:18:19 2017
Copyright (c) 1982, 2013, Oracle.  All rights reserved.

Connected to:Oracle Database 11g Enterprise Edition Release 11.2.0.4.0 - 64bit ProductionWith the Real Application Clusters and Automatic Storage Management options
SQL> show parameter spf
NAME             TYPE   VALUE------------------------------------ ----------- ------------------------------spfile             string   +OCR/rac-cluster/asmparameterf             ile/registry.253.940267187
SQL> create pfile=/home/grid/asmpfile.ora from spfile;
File created.
SQL> create spfile=+NEWOCR from pfile=/home/grid/asmpfile.ora;
File created.

五. 删除OCR原位置的ASM磁盘组OCR

1. 删除旧的OCR磁盘组的原位置（在一个节点执行就可以）：


[root@rac1 ~]# su - grid
[grid@rac1 ~]$ su rootPassword: 
[root@rac1 grid]# ocrconfig -delete +OCR

2. 查看OCR和voting disk新的状态与位置（所有节点）：

节点1：

[root@rac1 grid]# ocrcheck && crsctl query css votediskStatus of Oracle Cluster Registry is as follows :   Version                  :          3   Total space (kbytes)     :     262120   Used space (kbytes)      :       3464   Available space (kbytes) :     258656   ID                       : 1896437032   Device/File Name         :    +NEWOCR                                    Device/File integrity check succeeded
                                    Device/File not configured
                                    Device/File not configured
                                    Device/File not configured
                                    Device/File not configured
   Cluster registry integrity check succeeded
   Logical corruption check succeeded
##  STATE    File Universal Id                File Name Disk group--  -----    -----------------                --------- --------- 1.

ONLINE   08ab4466be804f48bfea02f300de046a (/dev/raw/raw9) [NEWOCR]Located 3 voting disk(s).

六. 重启整个集群（所有节点）

[root@rac1 ~]# su - grid
[grid@rac1 ~]$ su rootPassword: 
[root@rac1 grid]# crsctl stop crs && crsctl start crs  -- 重启集群

七. 将旧的OCR磁盘组drop掉

1. 检查ASM实例的参数文件（参数文件路径是否是新添加的OCR磁盘组）：

[root@rac1 ~]# su - grid
[grid@rac1 ~]$ sqlplus / as sysasm
SQL*Plus: Release 11.2.0.4.0 Production on Fri Apr 7 19:46:30 2017

3. 最后将旧的磁盘组mount并drop掉（在一个节点执行）：

[root@rac1 ~]# su - grid
[grid@rac1 ~]$ sqlplus / as sysasm
SQL*Plus: Release 11.2.0.4.0 Production on Fri Apr 7 20:00:27 2017
Copyright (c) 1982, 2013, Oracle.  All rights reserved.

Connected to:Oracle Database 11g Enterprise Edition Release 11.2.0.4.0 - 64bit ProductionWith the Real Application Clusters and Automatic Storage Management options
SQL> alter diskgroup OCR mount;
Diskgroup altered.
SQL> drop diskgroup OCR including contents;
Diskgroup dropped.

注意：旧的磁盘组只允许在一个节点mount，如果发现多个节点mount，需要在其他节点dismount，否则会删除不掉旧的磁盘组

[grid@rac1 ~]$ asmcmdASMCMD> lsARCH/DATA/NEWOCR/
