然后检查tsm actlog 发下如下信息:

ANR8944E Hardware or media error on drive 3310DRV2

然后查看713进程为：

ANR4930I Reclamation process 713 started for primary
storage pool WINPOOL automatically, threshold=48,
duration=None. (PROCESS: 713)

应该是在磁带进行回收的时候报的错，可是我的备份都能正常进行，并且drive也都正常，磁带也换过，清洗设置为自动清洗，不知道是什么原因造成的，能帮我排查一下问题吗？(带库用的是TS3310，TSM版本为5.5.6.)
