11g R2替换OCR盘：

检查OCR盘信息：

[root@s2-11g grid]# ocrcheck -config

Oracle Cluster Registry configuration is :

Device/File Name         :    +OCRVOT

[root@s2-11g grid]# more /etc/oracle/ocr.loc

ocrconfig_loc=+OCRVOT

local_only=FALSE

新添加替换的OCR磁盘组：

[root@s2-11g grid]# ocrconfig -add +NOCRVOTE

检查添加的磁盘组：

[root@s2-11g grid]# ocrcheck -config

Oracle Cluster Registry configuration is :

Device/File Name         :    +OCRVOT

Device/File Name         :  +NOCRVOTE

[root@s2-11g grid]#

[root@s2-11g grid]#

[root@s2-11g grid]# more /etc/oracle/ocr.loc

#Device/file  getting replaced by device +NOCRVOTE

ocrconfig_loc=+OCRVOT

ocrmirrorconfig_loc=+NOCRVOTE

local_only=false

删除原先磁盘组：

[root@s2-11g grid]# ocrconfig -delete +OCRVOT

[root@s2-11g grid]# more /etc/oracle/ocr.loc

#Device/file +OCRVOT getting replaced by device +NOCRVOTE

ocrconfig_loc=+NOCRVOTE

local_only=false

[root@s2-11g grid]# crs_stat -t

至此，OCR磁盘组替换完毕

11gR2 RAC vote盘替换

该操作时基于上篇OCR盘替换

首先介绍几篇metalink上关于OCRVOTE盘管理文章：

OCR / Vote disk Maintenance Operations: (ADD/REMOVE/REPLACE/MOVE) [ID 428681.1]：

增加和删除voting disk的命令在11gR2中不在被使用，所以我们在增减删除vote盘会报一下错误：

CRS-4258: Addition and deletion of voting files are not allowed because the voting files are on ASM

11g中提供replace命令： crsctl replace votedisk +XXXX

以下描述在基于OCR盘已经替换完毕的情况下替换vote盘：

[root@s2-11g grid]# crsctl query css votedisk

##  STATE    File Universal Id                File Name Disk group

–  —–    —————–                ——— ———

1. ONLINE   856223a123894f6bbf2a5ed3081609ae (/dev/asm-ocr_vote) [OCRVOT]

Located 1 voting disk(s).

[root@s2-11g grid]# crsctl replace votedisk +NOCRVOTE

Successful addition of voting disk 80eabd79d1864f1cbf957583c40476d7.

Successful deletion of voting disk 856223a123894f6bbf2a5ed3081609ae.

Successfully replaced voting disk group with +NOCRVOTE.

CRS-4266: Voting file(s) successfully replaced

[root@s2-11g grid]# crsctl query css votedisk

##  STATE    File Universal Id                File Name Disk group

–  —–    —————–                ——— ———

1. ONLINE   80eabd79d1864f1cbf957583c40476d7 (/dev/asm-nocr_vote) [NOCRVOTE]

Located 1 voting disk(s).

[root@s2-11g grid]#

替换结束后还需要修改ASM的参数文件路径：

[grid@s1-11g ~]$ sqlplus "/ as sysasm"

SQL*Plus: Release 11.2.0.3.0 Production on Tue Sep 18 10:37:14 2012

Copyright (c) 1982, 2011, Oracle.  All rights reserved.

Connected to:

Oracle Database 11g Enterprise Edition Release 11.2.0.3.0 – 64bit Production

With the Real Application Clusters and Automatic Storage Management options

SQL> show parameter str

NAME                                 TYPE        VALUE

———————————— ———– ——————————

asm_diskstring                       string      /dev/asm*

可以看到asm_diskstring的路径为/dev/asm* 如果你新加的盘的路径不是这样，那么就需要修改该路径

SQL> show parameter spfile

NAME                                 TYPE        VALUE

———————————— ———– ——————————

spfile                               string      +OCRVOT/s1-11g-cluster/asmpara

meterfile/registry.253.7942469

99

以上显示ASM的spfile指向的任然是老的OCRVOTE盘

SQL> create pfile='/home/grid/init.ora' from spfile;

File created.

create spfile='+NOCRVOTE' from pfile='/home/grid/init.ora'

File created.

重启双节点的HAS进程 由于spfile存储在共享存储上，只需要在一节点修改，其余节点都可以认
