备份软件TSM问题

[VirtualRookit]

生产环境：带库TS3200(单驱动器)+TSM5.4.1+oracle11gR2 RAC
物理备份时报错，报错信息如下：

RMAN-00569: =============== ERROR MESSAGE STACK FOLLOWS ===============

ORA-19511: Error received from media manager layer, error text:

Recovery Manager complete.

求教，这是什么错误引起的。

引用 1 楼 wildwave 的回复:

这应该属于tsm的问题 检查下： ANS0326E (RC41) This node has exceeded its maximum number of mount points. tsm中设置的mount point最大数和当前分配的通道数是否一致

对的，单驱动器，以前备份了2个月都没问题，突然就报这错误不能备份了，郁闷。

检查下tsm的配置，修正过来 和Oracle应该没有关系
