删除备份报错的问题

lujiaguai

用run脚本备份数据到文件系统的某个路径，8个通道备份，备份集为93--100
然后有意删除了这个路径下的8个bkp文件
此时list backup； 依然可以看到这些备份集，并且状态依然显示为AVAILABLE，但实际应该为expired
首先我删除了备份集100
delete backupset 100; 是成功的，删除后再list backup,已经看不到备份集100
但是稍等一会时间后，再尝试删除备份集99，98，97等就失败报错
此时应该怎么删除这些实际处于expired状态的备份集
信息如下：
RMAN> delete backupset 98;

using channel ORA_DISK_2
