    • 1.确定损坏磁盘在ASM磁盘组中的磁盘名
    • set line 1000
    • col name for a30;
    • col failgroup for a50;
    • col path for a50;
    • select b.name,a.name,a.failgroup,a.path from v$asm_disk a,v$asm_diskgroup b where a.group_number = b.group_number order by 2;
    •  
    • 确定磁盘组信息，磁盘路径，把插到的坏的磁盘组那一行全部复制出来：
    • NAME                   NAME                  FAILGROUP                      PATH
    • SSDDG                   SSDDG_0057              SDDDGSTO3                      /dev/qdata/mpath-1s03.3263.01.P3B00S21
    •  
    • 2.从ASM中删除该ssd盘
    • alter diskgroup <dgname> drop disk <disk_name> force;
    •  
    • alter diskgroup ssddg drop disk ssddg_0057 force;
    •  
    • 3.重平衡数据
    • alter diskgroup <dgname> rebalance power 11;
    •  
    • alter diskgroup ssddg rebalance power 11;
    •  
    • 4.确认重平衡进度
    • asmcmd lsop    该命令返回无结果，则可进行下一步
    • crsctl status res -t   //确认集群状态
    •  
    •  
    • 5.存储节点上qlink中删除该盘
    • qdatamgr qlink del_lun -p 3261 -t 1 -b /dev/qdisk/Pxxx
    • qdatamgr qlink show -t   //确认存储节点的target
    •  
    • qdatamgr qlink show -t
    • qdatamgr qlink del_lun -p 3263 -t 1 -b /dev/qdisk/P3B00S21
    • qdatamgr qlink show -t
    •  
    • 计算节点查看该盘的状态：
    • qdatamgr qlink show -c | grep -P -A7 P3B00S21
    •  
    • 6.将坏盘从操作系统detach
    • qdatamgr media detach_disk -s Pxxxx
    •  
    • qdatamgr media detach_disk -s P3B00S21
    •  
    •  
    • 7.将磁盘槽位灯点亮，确定磁盘的物理位置，更换磁盘
    • qdatamgr media lighton -s Pxxxx
    •  
    • qdatamgr qlink show -t
    • qdatamgr media lighton -s P3B00S21
    •  
    •  
    • 8.新的SSD重新插入
    • 9.初始化新的磁盘
    • qdatamgr media attach_disk -s Pxxxx
    •  
    • qdatamgr media attach_disk -s P3B00S21
    •  
    •  
    • 10.qlink中添加新盘
    • qdatamgr qlink add_lun -p 3261 -t 1 -b /dev/qdisk/Pxxxx
    •  
    • qdatamgr qlink add_lun -p 3263 -t 1 -b /dev/qdisk/P3B00S21
    •  
    •  
    • 11.qlink中确认加载的新盘
    • qdatamgr qlink show -c | grep -P -A7 Pxxxx
    • qdatamgr qlink load -r     //计算节点重新load
    •  
    • qdatamgr qlink show -c | grep -P -A7 P3B00S21
    •  
    •  
    • 12.ASM中重新加入新盘
    • alter diskgroup ssddg add failgroup datasto1 disk '/dev/qdata/mpath-1s01.3261.01.P0B00S02' force;
    •  
    • alter diskgroup ssddg add failgroup ssddgsto3 disk '/dev/qdata/mpath-1s03.3263.01.P3B00S21' force;
    • alter diskgroup ssddg rebalance power 11;
    •  
    • select b.name,a.name,a.failgroup,a.path from v$asm_disk a,v$asm_diskgroup b where a.group_number = b.group_number order by 2;
    •  
    •  
    • +++++++++++++++++++++++++++++++++++++++++++++++++++++==
    •  
    • 确定磁盘位置：
    • set line 1000
    • col name for a30;
    • col failgroup for a50;
    • col path for a50;
    • select b.name,a.name,a.failgroup,a.path from v$asm_disk a,v$asm_diskgroup b where a.group_number = b.group_number order by 2;
    •  
    •  
    •  
    •  
    •  
    •  
    • 删除磁盘后，查看asm磁盘组的状态：
    • su – grid
    • asmcmd lsdg
    • asmcmd lsop
    • 节点2上的磁盘组状态：
    • 重平衡数据：
    •
