Thanks to everyone for their input on creating copypools on disk ( and wildcard deletes)
I discovered a few things from a typo. I entered an incorrect directory name in the device class def and TSM dymanicly created the directory and file-volumes in that directory. That led to some confusion until I discovered that. Also, when I corrected the def and the ones dynamcily created were not available it led to a lot of error messages and freezing of the TSM server. As to the question of preformatting. I question if it makes sence on volumes created on RAID5 disks. RAID5 will spread the allocations across disk in any event. Also since initially TSM creates them as it needs them, one at a time, that is the same as explicitly creating them with the wait option. Also, TSM has a default size of 2GB. I changed that to 50GB. That 50GB will be allocated at the point in time of creation and would be as contiguous as explicitly formatting. Also, it would be deallocated when deleted as a single 50GB, so I'm not sure in a RAID5 environment if it would lead to more fragmentation if TSM allocated them rather than my explicitly allocating them. I did set the reclaim to 20% rather than 50% to reduce the wasted space on the disk, but disk to disk transfers are much faster than volume to volume.
