描述：物理机做dlpar，有三个分区，一个外挂磁带机，目前磁带机在第一个分区，但是无法移动到另外两个分区，操作如下：
# lsdev -Cc tape

# rmdev -l sissas1 -R
Method error (/usr/lib/methods/ucfgdevice):

删除提示busy，应该是因为sata1这个的问题吧？请问怎么处理呢？各位大侠
# lsdev -Cc tape
rmt0 Defined 02-00-00 SAS 1/2-inch Cartridge Tape Drive
rmt1 Available 03-00-02 Other FC SCSI Tape Drive
rmt2 Available 03-00-02 Other FC SCSI Tape Drive
rmt3 Available 03-00-02 Other FC SCSI Tape Drive
rmt4 Available 03-00-02 Other FC SCSI Tape Drive
这里看到rmt0磁带机已经defined的了，但是，无法把磁带机移动到别的分区
各位帮忙看看如何处理，谢谢了！
