We are in the midst of replacing our existing 3590J cartridges with 3590J cartridges that have been (supposedly) upgraded to allow 20/40 gigabyte capacity instead of of 10/20 capacity. I can successfully checkin the new libvolumes but until they actually get used, I have no way of even guessing how much data they can hold. I want to verify that the new 3590J cartridges we just bought have really been upgraded to support 20/40 capacity. Is there a way to force data to goto my new libvolume? Maybe there is a atape (or whatever the AIX command is) command to do this? Since we are replacing existing 3590J cartridges that are labeled 100000-100300 with (supposedly upgraded) 3590J cartridges with the same labels, do I have any potential problems in store other than removing a libvolume that still has data on it? They will all stay in the same device class.
TIA, John
