Question

我在IBM TSM 7.1上遇到了主要池空间回收的测试环境问题。

虽然有多个卷可回收空间我总是得到这个错误：

tsm: SERVER1>reclaim stg stgnasdisk thr=60 dura=60 wait=yes
ANR2111W RECLAIM STGPOOL: There is no data to process for STGNASDISK.
ANS8001I Return code 11.

100％的回收阈值是正常的，这是为了防止备份期间的回收。每天在维护管理中开始填海工程。

非常欢迎任何有关此方面的帮助。我在网上搜索过但没有找到任何解决问题的方法。

Answer 1

向IBM询问此问题。 TSM至少需要1个池而不进行重复数据删除，否则即使数据过期也不会回收主要的重复数据删除池。

在测试环境中，我有重复数据删除的主池和副本池。

我创建了一个非重复数据删除副本池，并且回收现在正常工作。

IBM TSM 7.1回收不适用于主池
