centos6.3 64位连接磁盘阵列重启后本地磁盘变为sdb

ding402

IBM的ds3512光纤存储，之前映射给1台centos6.1 64位，打了多路径补丁重启后正常，存储是sdb，本地是sda，现在新装一台centos6.4，将映射给6.1的那个存储分区映射给6.4并把6.1的映射断开，存储变成了/dev/mapper/mpathap1，重启后本地硬盘便成了sdb了，请问有什么解决的办法？本地硬盘只分了boot,swap和/,存储分区有1T,下面是df -h和fdisk -l显示的内容，希望高手指教啊，谢谢！

你检查下你正常的机器的udev设置,然后在你新机器上配置下udev的rules,测试下

配置multipath，绑定wwid和alias
