问题描述：
提供iscsi服务的是一台QNAP TS-439 Pro II
客户諯是一台 suse 10.1 x86_64
现在问题的问题是：从客户端电脑上挂载scsi目标是OK的，我进去分区也是OK的，可是当我格式化分区的时候就会出现如下提示：

......省略无数条与以下相似内容------

然后我试着用windows的initiator去挂载scsci目标并格式化，也是正常的。再连回到linux下也是正常。并能够正常读取里面的内容。可是当我将大量文件拷贝进去的时候，又出现了上述问题。莫名其它的连接就断了。

应该可以排除qnap设备的原因，因为同样在里面建的一个scsi目标，用另一台电脑挂载上去并使用是正常的。

不知道我是哪里漏掉了哪个重要步骤，烦请知情者能够不吝赐教
