OK So I have AIX 4.3.2 currantly on my system. I want to upgrade but have no space to do this. I have a New 9GB drive I just added to the system. I want to get rootvg from my currant 1GB drive to my new 9GB drive. I dont want to extend vg across multiple drives. I would like to totally move it to its own drive. I believe it is possible to mirror it I have to use the chvg -t option but I dont understand how I come up with the number I use with this option. Can anyone help with this?
