在正常的节点查看data5磁盘组所包含的磁盘，
因为系统使用asmlib，使用oracleasm查看，发现data5的都不存在，
[root@rac1 admin]# oracleasm listdisks NEW1 NEW2 NEW3 NEW4 NEW5 NEW6 VOL1 VOL10 VOL11 VOL12 VOL13 VOL14 VOL15 VOL16 VOL17 VOL18 VOL2 VOL3 VOL4 VOL5 VOL6 VOL7 VOL8 VOL9 VOLDATA1 VOLDATA10 VOLDATA11 VOLDATA12 VOLDATA13 VOLDATA14 VOLDATA15 VOLDATA16 VOLDATA17 VOLDATA18 VOLDATA19 VOLDATA2 VOLDATA20 VOLDATA21 VOLDATA22 VOLDATA23 VOLDATA24 VOLDATA25 VOLDATA26 VOLDATA27 VOLDATA28 VOLDATA29 VOLDATA3 VOLDATA30 VOLDATA31 VOLDATA32 VOLDATA33 VOLDATA34 VOLDATA4 VOLDATA5 VOLDATA6 VOLDATA7 VOLDATA8 VOLDATA9 VOLREDO1 VOLREDO2 [root@rac1 admin]# oracleasm querydisk -p VOL1 Disk "VOL1" defines a device with no label
发现VOL1这个磁盘的Lable丢失。

扫了下盘，擦lable都丢失。
找到以前的记录确定了具体磁盘，使用powermt查看盘状态

备份磁盘头
[root@rac2 admin]# dd if=/dev/emcpowerc1 of=/tmp/VOL1.50m.dd bs=1M count=50
使用oracleasm renamedisk,这里加-f是强制修改
[root@rac2 disks]# oracleasm renamedisk -f /dev/emcpowerc1 VOL1 Writing disk header: done Instantiating disk "VOL1": done
两个节点扫盘、查看
[root@rac2 disks]# oracleasm listdisks VOL1 ....略 [root@rac1 admin]# oracleasm scandisks Reloading disk partitions: done Cleaning any stale ASM disks... Scanning system for ASM disks... Instantiating disk "VOL1"
按照此步骤修复了出问题的磁盘，手工mount磁盘组，库正常打开。
奇怪的问题，此库刚恢复了没几天，正在运行竟然asmlib的label丢失了。。。。。。
