1 06/11/76  Attaching and Detaching Logical Volumes
 2 
 3 Before a process can access a segment stored on a private logical volume, the
 4 logical volume must be attached (Type "help attach_lv"). Each process wishing to
 5 access the segment must individually attach the logical volume.
 6 An attempt by a process to use a segment on a private logical volume that is
 7 not attached results in an error message.
 8   The user must have rw access to the Access Control Segment (ACS) of the
 9 volume in order to attach it. The ACS is maintained by the volume's owner.
10   A logical volume remains attached until the process explicitly detaches it
11 (type "help detach_lv").
