TSM 在使用copypool的情况下，lanfree是否可以生效正常使用呢？

什么版本的TSM？
另外你看看是不是开了同步写？
The server disqualifies a storage pool from being a LAN-free-enabled storage pool if it was configured for simultaneous-write operations.

In this case, data from the client is sent directly to a server that will not be using a LAN-free storage pool.

Issue the QUERY STGPOOL stgpoolName F=D command for the destination storage pool for this client. If the storage pool is set for simultaneous-write operations, the "Copy Storage Pool(s):" value references one or more other storage pool names and IBM Spectrum Protect™ interprets the simultaneous-write operation to be a higher priority than the LAN-free data transfer. Because simultaneous-write operations are considered a higher priority operation, this storage pool is not reported as LAN-free-enabled and as such, the client sends the data directly to the server. The storage agent does not support simultaneous-write operations.

应该是tsm 的storage agent不支持同步写stgpool的功能，所以lanfree失效
