RMAN SBT_TAPE备份无法被DISK通道识别

经过测试确认rman SBT_TAPE通道备份的rman备份集无法被DISK通道(文件系统方式备份)方式恢复,关于rman的SBT_TAPE通道(带库方式备份)备份参考:模拟带库实现rman远程备份
发起SBT_TAPE通道备份备份

确认备份文件在文件系统中位置

[oracle@xifenfei ~]$ ls -l /tmp/rmanback/ctl_20240714_0r2vt3eh_1_1.rman
-rw-r--r-- 1 root root 9961472 Jul 14 13:19 /tmp/rmanback/ctl_20240714_0r2vt3eh_1_1.rman

尝试DISK通道加载备份集,报RMAN-07519错误

通过分析备份文件发现在带库方式备份和文件系统方式备份的文件头信息明显不一样
