Hi,
During OS installation the installation routine will create (or will have created) a volume group called rootvg consisting of hdisk0 containing the logical volumes and filesystems pertaining to the OS (e.g. /, /usr, /var etc.)
Next, you will have to decide whether to create an additional volume group consisting of hdisk1 and hdisk2 to contain your data, or whether to extend rootvg by hdisk1 and hdisk2 to place the data there.
It's good and normal practice to create an additional volume group, so I'd recommend doing it this way.
The simplest way is to use "smitty mkvg" (choose "Scalable ...") to create the volume group and "smitty crfs" (choose "Enhanced...") to create filesystems along with their mountpoints (that's probably what you call "folder").
Should you need assistance with this, please let me know. I'll help you.
