RAC上ocr和voting disk从10.1到11.2维护操作和需求的差异
检查当前的ocr所在磁盘：
[oracle@dm01db01 ~]$ ocrcheck
Status of Oracle Cluster Registry is as follows :
Version : 3
Total space (kbytes) : 262120
Used space (kbytes) : 2612
Available space (kbytes) : 259508
ID : 1194723922
Device/File Name : +DATA_DG
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 bypassed due to non-privileged user
添加+DBFS_DG作为新的存放ocr的磁盘组：
[oracle@dm01db01 ~]$ ocrconfig -add +DBFS_DG
PROT-20: Insufficient permission to proceed. Require privileged user
[oracle@dm01db01 ~]$ su
Password:
[root@dm01db01 oracle]# ocrconfig -add +DBFS_DG
[root@dm01db01 oracle]# exit
exit
[oracle@dm01db01 ~]$ ocrcheck

[oracle@dm01db01 ~]$ su

删除+DATA_DG上的ocr：
[root@dm01db01 oracle]# ocrconfig -delete +DATA_DG
[root@dm01db01 oracle]# ocrcheck
Status of Oracle Cluster Registry is as follows :
Version : 3
Total space (kbytes) : 262120

Device/File integrity check succeeded
Device/File not configured
Device/File not configured
Device/File not configured
Device/File not configured

[root@dm01db01 oracle]#
查看voting disk当前存放在哪个磁盘组（N中方法，这里直接在ASM里面看的）：
[oracle@dm01db01 ~]$ . ./env/grid.env
[oracle@dm01db01 ~]$ asmcmd
ASMCMD>
ASMCMD> lsdg
State Type Rebal Sector Block AU Total_MB Free_MB Req_mir_free_MB Usable_file_MB Offline_disks Voting_files Name

[/shell]
还可以使用crsctl query css votedisk来查看：
[oracle@dm01db01 ~]$ crsctl query css votedisk ## STATE File Universal Id File Name Disk group -- ----- ----------------- --------- --------- 1. ONLINE 678abf64d3c34f9dbf923ab1420f40c0 (o/192.168.11.13/DATA_DM01_CD_00_dm01cel01) [DATA_DG] 2. ONLINE 80581891d0414fb6bf397f8c0d14ff3d (o/192.168.11.14/DATA_DM01_CD_00_dm01cel02) [DATA_DG] 3.

将voting disk替换到+DBFS_DG磁盘组：
[oracle@dm01db01 ~]$ crsctl replace votedisk +DBFS_DG Successful addition of voting disk af022878bf3f4f2dbfa2c3f630ee15b9. Successful addition of voting disk 83dd62df08da4f32bf71abefc6d8ee52.
