关于overlaps with device in d11的解决办法

这种情况应该只发生在使用SUN阵列里有不同厂家的硬盘的时候。

如果磁盘没有一个唯一的ID的话SDS和VXVM没办法使用，因为是SCSI的阵列，所以存在SCSI ID

的问题。那么如果不是一个厂家的硬盘就存在标识的问题，那么SDS和VXVM不能正确的判断分

区的重叠，怎么解决呢？
问题的关键在于 /kernel/drv/sd.conf这个文件。

确定厂商和硬盘信息

看到我们查询到的信息了吧，我们把它增加到/kernel/drv/sd.conf里面
格式为
sd-config-list=
         "vendorproduct       ", "anystring";
anystring=1,0x8,0,0,0,0,0;
"vendorproduct       "记录有24位组成，分别是8位的vendor string和16位的product

string.如果不够长度用空格补齐，"anystring"没什么限制，它是作为标识符匹配下一行，

1,0x8,0,0,0,0,0是传输的标记，不要用相同的

修改完了重新启动reboot -- -r
