TSM备份报错，如何处理？
我怀疑我的磁带空间没释放导致的。
报错如下：

如何让他释放呢？
oracle客户端检查了脚本：有释放脚本。
求各位大哥帮忙看看？

2种方法：
1. 删除老的备份2. 如果数据的合规要求 要求保留，不能删除，则扩容磁带。收起的却是在rman脚本里加入过期删除，
delete noprompt obsolete recovery window of 30 days;
delete noprompt expired backup;
然后在tsm上执行
expire inventory
q libv是否还有scratch的磁带，如果没有可能存储池空间不足了，报错里显示的。你需要做过期处理，你指定的数据是保留多久啊？你执行的命令是不是以rman默认的参数做过期呢？
expire inventory标记过期试试，如果还没有清理过期数据，是不是你的数据还没过期呢？
我之前用天数的比较多：
delete noprompt obsolete recovery window of 30 days;
delete noprompt expired backup;
收起- 大哥，这个是oracle rman执行吧
- 研究了半天，应该是oracle端执行过期删除的天数大于我tsm里面设置的天数，所以没释放
- 是rman的脚本里的。
ANS1329S (RC29) Server out of data storage space，没有备份空间了
- 看着了啊，我问为什么没回收，我oracle里面已经写了过期删除啊？
- 如果备份文件已被孤立到tsm了，rman删不了
