If you want the volume to be a non-system volume (i.e. not a member of
the MPEXL_SYSTEM_VOLUME_SET), you do not want to add it via the AVOL
command in the IO section of SYSGEN. That method will only add member
volumes to the system set.
 
To add the volume to the system as a member of a pre-existing user
volume set, you will use the NEWVOL command in VOLUTIL, giving the
volume a unique VNAME (not totally unique but definitely a name not
in use for an already existing volume in that set) and specifying
the name of the set to which it is being added.
 
To add the volume as the master volume of a new volume set, you will
use the NEWSET command specifying a unique set name (SNAME) and
giving the volume itself a volume name (VNAME).
 
There are 2 general conventions used for naming the members in a
volume set. One is to name the volumes, starting with the master,
as MEMBERx, where 'x' starts at '1' for the master volume and is
incremented for each additional volume in the set. The other is
to name the volumes MEMBERxxx, where 'xxx' is the ldev number of
the disc drive. This second method would cause confusion on a
system with removable disc packs, but since that is almost unheard of
today this convention can be quite useful.
 
Of course, you can name the set anything you want and then use
arbitrary names for the volumes. It does not matter one bit to the
operating system. However, using one of the above conventions makes
life easier and I would recommend the second one.
