When you use disk reclamation pool, TSM takes data off the tape, puts in the reclamation pool. When the RECPOOL fills to the highmig threshold, TSM will start migration for the RECPOOL. It will call for a filling or scratch tape in the original pool, then move the files from RECPOOL back there. With only 1 drive, you obviously have to do one of these things (either reclamation or migration) at a time. It's the only way to do reclamation when you only have 1 drive.
If you force the data back out by causing RECPOOL to migrate, TSM will call for a tape mount of a FILLING or SCRATCH tape in the original pool, and empty out the RECPOOL down to the lowmig threshold. If you just start reclaim again, it will call for a mount of a tape in the original pool to continue reclamation where it left off; and continue taking data off the tape and adding to the RECPOOL. Just don't try to force any DELETEs, and you can't do any harm trying this stuff out! TSM won't do anything that hurts your data, unless you force it to. The only destructive things you can do are: DELETE VOLUME (with DISCARDDATA=YES) DELETE FILESPACE LABEL LIBV (with OVERWRITE=YES) -deleting files out from under TSM at the OS level Wanda Prather "I/O, I/O, It's all about I/O" -(me)
