Thanks, I missed this. This method would be less disruptive.

Re: SFS - Moving File Pool Minidisks to Different Physical Devices






You can create a storage group 3, move your filespaces to it with FILESERV 
MOVEUSER, then disable storage group 2 with FILEPOOL DISABLE GROUP 2 
EXCLUSIVE DETACH.  You can then replace the old storage group 2 minidisks 
with 1-cylinder minidisks.  This isn’t completely transparent, because 
FILESERV is a dedicated maintenance mode command, but it does allow you to 
move users in batches, without requiring an outage long enough to back up, 
format, and restore the entire pool.  I have code in the SFS server 
PROFILE EXEC to look for a move list and process it at system IPL time.
