tsm backup ans1228e,ans1304w错误

Retry # 2  Expiring-->              302,024 /backup/ofptrace/0610042216.tar.Z  ** Unsuccessful **
ANS1228E Sending of object '/backup/ofptrace/0610042216.tar.Z' failed
ANS1304W An active backup version could not be found.

报了很多这样的错误，在网上查了查，说
Under certain conditions, the TSM client journal service can
attempt to send an expiring object twice, resulting in errors on
the second attempt. The following errors will be reported to the
user and dsmerror.log:
  ANS1228E Sending of object '\\machine\c$\a\b\file.txt' failed
  ANS1304W An active backup version could not be found.
.
TSM should not send the second expiring object message as a part
of the journaled backup operation, since it was already handled
previously.


我刚刚学习tsm，不是很了解！

想知道这种问题怎么解决呢？

下面是Ibm关于这个问题的解决办法，我没有看懂

原因找到了，有一盘磁带offline了，客户端请求expire上面的文档，找不到，就是这个错了

感谢lz能够完整解决一个问题
