替换存储表决磁盘的ASM

1.新加三块共享盘设置权限（记得两个节点都做处理）
[root@rac1 ~]# raw /dev/raw/raw6 /dev/sdg
/dev/raw/raw6:  bound to major 8, minor 96
[root@rac1 ~]# raw /dev/raw/raw7 /dev/sdh
/dev/raw/raw7:  bound to major 8, minor 112
[root@rac1 ~]# raw /dev/raw/raw8 /dev/sdi
/dev/raw/raw8:  bound to major 8, minor 128
[root@rac1 ~]#
[root@rac1 ~]# chown grid:asmadmin /dev/raw/raw6
[root@rac1 ~]# chown grid:asmadmin /dev/raw/raw7
[root@rac1 ~]# chown grid:asmadmin /dev/raw/raw8
[root@rac1 ~]# 
[root@rac1 ~]# chmod 660 /dev/raw/raw6
[root@rac1 ~]# chmod 660 /dev/raw/raw7
[root@rac1 ~]# chmod 660 /dev/raw/raw8
2.创建一个磁盘组，包含一个投票故障组
[grid@rac1 ~]$ sqlplus / as sysasm

  2    v$asm_diskgroup v1, v$asm_disk v2
  3      where v1.group_number = v2.group_number
  4        and v1.name = upper('ocr_data');

3.将表决磁盘文件迁移到新创建的磁盘组：
[root@rac1 bin]# ./crsctl query css votedisk
##  STATE    File Universal Id                File Name Disk group
--  -----    -----------------                --------- ---------
1. ONLINE   924682b9e7fb4fa5bf93e8a2a12a916f (/dev/raw/raw1) [OCR]
2. ONLINE   39d0f0108a734f32bf1aee2abf464db3 (/dev/raw/raw2) [OCR]
3. ONLINE   3e457cf73bba4f06bf92ca64e672f796 (/dev/raw/raw3) [OCR]
Located 3 voting disk(s).
[root@rac1 bin]# ./crsctl replace votedisk +OCR_DATA
Successful addition of voting disk 74692688b1184fcebf04f871a1fa0f31.

4.查看磁盘组
SQL> col name for a10
SQL> select v1.name, v2.failgroup, v2.failgroup_type, v2.total_mb, v2.free_mb from
  2    v$asm_diskgroup v1, v$asm_disk v2
  3      where v1.group_number = v2.group_number
  4        and v1.name = upper('ocr_data');

NAME       FAILGROUP                      FAILGRO   TOTAL_MB    FREE_MB
---------- ------------------------------ ------- ---------- ----------
OCR_DATA   FG2                            REGULAR       5120       5035
OCR_DATA   FG1                            REGULAR       5120       5035
OCR_DATA   FG3                            QUORUM        5120       5086
[root@rac1 bin]# ./crsctl query css votedisk

--  -----    -----------------                --------- ---------
