Error: MDM failed command. Status: Only a single SDC may be mapped to this volume at a time

映射一个volume到多个SDC的时候报错如下:

Error: MDM failed command.  Status: Only a single SDC may be mapped to this volume at a time

从上图可以看到创建volume, 映射volume都成功了, 再映射一个的时候报了错.

暂时的解决方法如下:

scli --unmap_volume_from_sdc --volume_name VMOS --sdc_ip 172.16.3.122
scli --map_volume_to_sdc --volume_name VMOS --all_sdcs --i_am_sure

奇怪, 难道不能指定一个volume只被某几个SDC访问么? 要么就一个, 要么就全都行?

Error: MDM failed command. Status: Only a single SDC may be mapped to this volume at a time
