If you press PF1 for help, press “enter to continue” and select option 6 Data Column Descriptions it gives all of the columns names. They have a name and number.
Back in the data display, you can scroll sideways to display these field.
You can use the command view 3,23 to display just those fields, or view * to display all of the fields.
You can use view save name and view select name to save the current view configuration as name.
I could not find a way of displaying all of the attributes for a volume in a vertical list.
Sort
You can say sort 3 to sort by column 3 ascending, or just sort where you can specify the columns and ascending or descending.
The columns you can sort by depend on what are displayed via the view command.
