Larry, I recently performed this conversion on all of our TSM servers.
To simplify the process, I allocated the new container pool directories on the same mountpoints and volume groups that held the FILE class data. That way, as your file volumes empty into the container class pool, you shouldn't need more than 25% free space to keep things running smoothly. The convert stgpool process ran relatively quickly, I converted 250TB FILE data to container in a few weeks. For TSMB, I'd delete the storage pool with devclass file and create a new container class pool to take it's place. Then set up storage pool replication to seed TSMB with TSMA data as the conversion process moves through your data. The convert process can (and should) be scheduled to run during quiet periods for a set duration. We ran ours for 6 hours a day. Let me know how you make out, but you should have no issues. It ran smoothly on all of our servers, from the smallest instance with ~10TB to our primary server with ~250TB.

Each systems sequential FILE pool is comprised of 174 - 50GB volumes. Currently the primary server TSMA has 3.2TB of used space, with nothing yet on TSMB. Our intention was to have TSMA be the primary backup server, and TSMB be the offsite server, using Node Replication to sync the servers daily. Deduplication is not active at this point, but based on my IBM videos and documentation it should be turned on with storage containers. Looking for some assistance. Has anyone converted from using a FILE dev class configuration to Storage Containers? All disk drive space has been allocated. Should I begin removing volumes to free up space so that I can create an LVM for the storage pool container directory? Then slowly move the currently allocated node backup data on the volumes to the storage containers? Any assistance would be greatly appreciated.
