  •  
  • 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.ASM中删除该ssd
  • alter diskgroup drop disk force;
  •  
  • alter diskgroup ssddg drop disk ssddg_0057 force;
  •  
  • 3.重平衡数据
  • alter diskgroup 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;
