Hi Bojianli

What is the best practice for DD ? it don' t support my old configuration ?

Hi Bojianli

Thanks for your support, now the server can detect all the drivers.

用中文总结下本帖的问题与回答，以便网友围观。

我有50个驱动器，其中一半映射到了active 1a passive 1b，另一半映射到了1b active 1a passive。现在redhat不能自动识别到映射到host2上的驱动器，我只能用如下命令手动添加。

echo "scsi add-single-device 2 0 1 #" > /proc/scsi/scsi "#" is (2,4,6,8...50)

请问：如何能让redhat自动检测到所有驱动器？

zone:

host1----1a

host2----1b

创建两个access groups，每个group有一个initiator，在每个组上重新启动LUN。
