解决办法：
[root@rac01 ~]# dd if=/dev/zero of=/dev/sdb bs=1024 count=2056
2056+0 records in
2056+0 records out
2105344 bytes (2.1 MB) copied, 0.252157 s, 8.3 MB/s
[root@rac01 ~]# dd if=/dev/zero of=/dev/sdc bs=1024 count=2056
2056+0 records in
2056+0 records out

然后重新分区：
[root@rac01 ~]# fdisk /dev/sdb

再重新创建asm磁盘
[root@rac01 ~]# oracleasm createdisk data01 /dev/sdb1
Writing disk header: done
Instantiating disk: failed
Clearing disk header: done
[root@rac01 ~]# oracleasm createdisk data02 /dev/sdc1
Writing disk header: done
Instantiating disk: failed
Clearing disk header: done

需要重启服务器
[root@rac01 ~]# reboot

再创建asm磁盘成功
[root@rac01 ~]# oracleasm createdisk data01 /dev/sdb1
Writing disk header: done
Instantiating disk: done
[root@rac01 ~]# oracleasm createdisk data02 /dev/sdc1
Writing disk header: done
Instantiating disk: done
