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,

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。。。。。。
