Server: TSM 5.1.9.0 on AIX 5.2 ML-2 Clients: TSM 5.1.7.0 on Windows 2000 SP3
Several months ago I reconfigured our TSM system to delay the purchase of yet another tape library, making liberal use of the MigDel parameter. Now, when the "front end" resources fill up, clients are not redirected to subsequent storage pools despite the configuration that says that they should. Specifically, the backup data path now is like this: Client -> disk -> 3575 -> LTO -> DLT -> shelf Because "disk" and "3575" are of limited capacity, I have assigned MaxSize and MigDel on both. Disk = 60 MB max size, MigDel = 2 days, MigCont = Yes, NextStg=3575 3575 = 2GB max size, MigDel = 14 days, MigCont = No, NextStg=LTO LTO accepts everything In practice, if the 3575 fills up, the client sessions "FAIL" rather than shift to the LTO. Yet, if the disk fills up, the client sessions do shift to the 3575. This is making it a real challenge to maintain reliable system operation until we decide what we want to do regarding storage expansion. Is this normal? Or have I encountered a bug? Thanks.
