I recalled a point that has bothered me for ages after following the recent posts regarding splitting the copypool and technote 1222377.
There is a general acceptance that it's ok to do things like, delete the volumes from the copypool and just let the backup storage pool recreate them. But, it's my understanding the copypool volumes are there to protect against issues such as read errors or otherwise unusable primary pool tapes. Is it really a good idea to be relying on the fact you can read the only copy of all your data once more? (Ok, we have read it once to make the second copy, but there have perhaps been many movements of the data around tapes and the file may not be on the piece of tape we know to have been reliable once). I think it would be much better of TSM to allow nodedata to be specifically deleted from a copypool, so long as TSM is aware there is another copy of the file in another copypool. Perhaps something like delete nodedata type=copy f=file,space,list? This would avoid the exposure in the first place. Matt.
