迁移描述：将ocr和votedisk从+DATE上迁移到+OCR_VOTE上；
操作如下： [root@ora2 ~]$ /u01/app/11.2.0/grid/bin/ocrcheck Status of Oracle Cluster Registry is as follows : Version : 3 Total space (kbytes) : 1469612 Used space (kbytes) : 3784 Available space (kbytes) : 1465828 ID : 1820175369 Device/File Name : +DATA Device/File integrity check succeeded Device/File not configured Device/File not configured Cluster registry integrity check succeeded Logical corruption check bypassed due to non-privileged user 这里我们看到ocr放在+DATA中了 然后Add a new OCR device/file： [root @ora2 ~]/u01/app/11.2.0/grid/bin/ocrconfig -add +OCR_VOTE [root @ora2 ~]$ /u01/app/11.2.0/grid/bin/ocrcheck Status of Oracle Cluster Registry is as follows : Version : 3 Total space (kbytes) : 1469612 Used space (kbytes) : 3784 Available space (kbytes) : 1465828 ID : 1820175369 Device/File integrity check succeeded +OCR_VOTE Device/File integrity check succeeded Device/File not configured Cluster registry integrity check succeeded Logical corruption check bypassed due to non-privileged user （这时候ocr并不存在于+OCR_VOTE中） 迁移 ocr： [root @ora2 ~]$/u01/app/11.2.0/grid/bin/ocrconfig -replace +DATA -replacement +OCR_VOTE 然后迁移votedisk： [root @ora2 ~]$su - grid [grid @ora2 ~]$crsctl replace votedisk +OCR_VOTE 查询一下votedisk的存放目录： [grid @ora2 ~]$crsctl query css votedisk; 查询一下资源状态: [grid @ora2 ~]$crsctl status resource -t 然后登录asm查看asmdisk的信息： sqlplus / as sysasm SQL> select group_number,name,state,type from V$asm_diskgroup; SQL> select group_number,name,path from v$asm_disk; 使用show parameter spfile查看路径，如果存放在+DATA中，可以重建spfile： 如下操作： SQL>create pfile='/u01/11.2.0/grid/dbs/asmpfile.ora' from spfile; SQL>create spfile='+OCR_VOTE' from pfile='/u01/11.2.0/grid/dbs/asmpfile.ora'; 然后使用root用户重启crs即可 [root @ora2 ~]$/u01/app/11.2.0/grid/bin/crsctl stop crs [root @ora2 ~]$/u01/app/11.2.0/grid/bin/crsctl start crs 然后再使用grid用户 su - grid SQL>alter diskgroup OCR_VOTE mount; 切换root用户 /u01/app/11.2.0/grid/bin/ocrconfig -delete +DATA删除磁盘组+DATA：
SQL>alter diskgroup DATA dismount; SQL>drop diskgroup DATA including contents--------------------------------------------------------------------------------------------
