因此找到原因：用于备份arch的2个driver，其中一个被磁带卡住，而另一个能正常工作，于是就显示了一半成功一半失败的备份结果。
在上述情况下，arch还是能完整的正常备份（只用一个driver），但是备份有报错信息。
问题解决：
到gd-rac02上执行以下语句，检查是否真的卡带：

mc 实用程序为用户提供了一个命令行接口，用于将介质操作命令发送到自动装载机或介质更换设备。它采用
“元素类型”作为大多数选项的参数。有效的介质类型(element_types) 包括：
D 指定数据传输(DT) 元素。
I 指定导入/导出(IE) 元素。
M 指定介质传输(MT) 元素。
S 指定存储(ST) 元素。
数据传输元素的示例是自动装载机的嵌入式磁带机。导入/导出元素的示例是可用于插入介质或者从自动装载机中
取出介质的插槽。介质传输元素的示例是自动装载机的机械拾取器组件。存储元素的示例是自动装载机的介质插
有关用法，请参阅下面的示例。
mc 采用下列选项和参数：
-a num 输出num 指定的驱动器插槽的SCSI 总线地址。
-b 0|1 向设备发出保留(1) 或释放(0) SCSI 命令。
确定从源到目标的移动是否有效。使用设备功能模式页，并将返回TRUE 或FALSE。源和目标
元素类型值中不应该使用空格。例如， -c DS 指定数据传输元素作为源，指定存储元素作为目
-e element_type 输出元素类型的元素数。请参阅上面的元素类型。可以指定多个类型。例如， -e IDSM 指定所
有有效的元素类型。
-h|-? 输出用法说明。
HP-UX 11i Version 2: September 2004 -1- Hewlett-Packard Company Section 1M-527
mc(1M) mc(1M)
-l 0|1 允许(0) 或防止(1) 取出介质。
-n num 输出num 指定的插槽中的驱动器序列号（如果该信息可用）。
-p device 指定到库设备的通道设备文件。如果已设置LIBRARY 环境变量，则可以省略-p 选项。
-q 输出供应商ID、产品ID 和产品修订标准查询信息。
-r element_type 输出元素类型的元素插槽的状态(FULL/EMPTY/NONE)。请参阅上面的元素类型。如果设备支
持条码信息，该信息将追加到状态。可以指定多个类型。例如， -r IDSM 指定所有有效的元素
指定移动介质源的元素类型和插槽号() 。元素类型和插槽号之间不应使用空格。例如，
-sS1 指定插槽号1 中的存储元素。每次调用时，指定该选项的次数不能超过两次。
指定移动介质目标的元素类型和插槽号。元素类型和插槽号之间不应使用空格。例如， -dD3 指
定插槽号3 中的数据传输元素。每次调用时，指定该选项的次数不能超过两次。
mc 在成功完成时返回0，在其他情况下返回-1。
ERROR: 0×5 Illegal Request: 0x3b0d Medium Destination element full
以上错误消息可能是用于将介质移动到已满的嵌入式驱动器的命令mc -s S2 -d D1 的结果。
ERROR: /dev/scsi/3: No such file or directory
如果不存在缺省的SCSI 通道设备文件，并且未指定其他任何设备文件，则将输出上面的错误消息。
以包含六个盒式磁带的磁带盒的DDS-2 自动装载机为例：
查看自动装载机的数据传输和存储元素类型的状态：
下面显示以上命令的输出示例。输出指示插槽2 (ST_slot_2) 中存在一个介质，嵌入式驱动器(DT_slot_1) 中存在
一个介质，其他所有插槽均为空。
DT_slot_1 FULL
ST_slot_1 EMPTY
ST_slot_2 FULL
ST_slot_3 EMPTY
Section 1M-528 Hewlett-Packard Company - 2 - HP-UX 11i Version 2: September 2004
mc(1M) mc(1M)
ST_slot_4 EMPTY
ST_slot_5 EMPTY
ST_slot_6 EMPTY
将介质从嵌入式驱动器移动到插槽5，然后将介质从插槽2 移动到嵌入式驱动器：
mc -s D1 -d S5 -s S2 -d D1
检查是否可以从数据传输元素移动到存储元素：
下面显示以上命令的输出示例。该输出指示从数据传输元素类型到存储元素类型的移动是有效的。
DT->ST: TRUE
请注意，对于所有HP DDS 自动装载机：首次使用mc 命令后，自动装载机将进入随机模式。一旦处于随机模
式，将禁用除Eject Button 之外的所有前面板按钮功能。要回到堆栈模式，必须弹出并重新插入磁带盒。
请注意，对于某些自动装载机或库：使用mc 命令之前，必须使用mt offline 命令卸载介质。
mc 命令支持所有符合SCSI-2 介质更换器命令规范的HP 支持设备。
在使用该命令操作自动装载机之前，必须配置SCSI 通道驱动程序并创建设备文件。
对于连接到SCSI 接口卡(PCI) 的设备，必须配置sctl 通道驱动程序。请参阅scsi_ctl(7) 。
mc 由HP 开发。
/dev/scsi/3 缺省的通道设备文件。
