六、添加asmdisk磁盘

1
SQL> alter diskgroup DATA add disk  '/dev/asm-diskf' name DATA_0002, '/dev/asm-diske' name DATA_0003 rebalance power 8;

七、查看进度

1
SQL> select * from v$asm_operation;

---任意节点执行:

删除磁盘组后，在crs资源里还是可以看到FRA磁盘信息，所以需要删除crs相关信息:

  1. 一、查看asmdisk
  2. 二、查看udev配置
  3. 三、查看归档日志存放路径
  4. 四、修改归档日志
  5. 五、删除FRA磁盘组
  6. 六、添加asmdisk磁盘
  7. 七、查看进度
  8. 八、验证磁盘
  9. 九、删除srvctl相应的资源(grid用户执行)
  10. 十、删除磁盘组依赖
    1. 1.查看crs资源
    2. 2.确认当前依赖关系
    3. 3.更新依赖信息
    4. 4.验证
