birdnet

/usr/openv/netbackup/bin/admincmd/bpmedia -freeze -m media_id

先冻结指定的介质，再看看是否会用别的磁带备份成功

在打开/dev/rmt/0cbn出错，有人介绍说通过删除/dev/rmt/下的内容，然后devfsadm -c tapes重新获取磁带库。但是按照此指示操作后，/dev/rmt/依旧为空，找不到0cbn，并且通过tpconfig -d也看不到带库驱动的状态。
最后没办法只能手工将0cbn连接到具体的目标devices上，通过tpconfig -d 可以看到具体的驱动状态，但是备份数据还是不行。


另之前做过直接往磁带上备份数据的测试，报错说/dev/rmt/0cbn不能open.

回复11楼：
已将源盘删掉过，nbu可以找到别的盘，错误还是一样。

最开始还怀疑磁头的原因，也用清洗带清洗过几次

删除之前有备份么?如果有可以恢复回去
1、关闭NBU /usr/openv/netbackup/bin/bp.kill_all  
2、重启磁带库
3、启动NBU /usr/openv/netbackup/bin/bp.start_all
4、测试备份文件系统到磁带是否正常

    这个测试过，重启nbu并且重新启动磁带库，都没有解决.

zhaoxinbbs

有其他带库吗？接一个上去试试

用robtest测试，可以将磁带移入到drive中，也可从drive中移出。 证明物理链路是正常的，有可能是NBU把driver 锁住了
可否贴出以下命令内容？
mt -f /dev/rmt/0cbn  status
/usr/openv/
/usr/openv/volmgr/bin/tpconfig -d
/usr/openv/volmgr/bin/vmdareq -a

#tpconfig -d
过去是可以显示driver up的，现在已经彻底down了

这两天有点忙没上来更新，见谅。
前天找服务商查了一下，服务商说连接线缆坏了，等线缆到位，更换后把结果告诉大家。
多谢各位！
