1.查询要弹出磁带的信息
可查询media日志，冻结，可用等，详情可查
查看带库空闲槽位
vmcheckxxx -rt tld -rn 0（0为带库名）
磁带详细信息：
bpmedialist -m 6666L4
vmquery -m 6666L4
2.弹磁带
#robtest
Robot Selection
---------------
1) TLD 0
2) none/quit
Enter choice: 1
Enter tld commands (? returns help information)
s p
Address 769, import_enabled = 1, export_enabled = 1, access = 1
except = 0, import_export = 0, full = 1
Barcode = B06666L4
表示槽位有磁带,那就从2开始弹出
Invalid command
m s282 p2

3. 加磁带
3.1将新磁带加入带库中
关上盖子，自动添加磁带到带库中
3.2添加磁带后更新带库
backup-01:/usr/openv/bpdbjobs_history # vmupdate -rt tld -rn 0 -empty_map

磁带入库后修改磁带类型（比如清洗带）：
vmchange -m 0066L4 -new_mt hcart3_clean
修改卷池 （清洗带放在NONE（0）号池，空白数据带在Scratch池）
vmpool -list_all -bx 查看卷池信息
vmchange -m 0066L4 -p 0
