The storage subsystem manager ($ZZSTO) is a generic process configured in the kernel subsystem.
$ZZSTO monitors and controls all storage subsystem objects. $ZZSTO has the object type of
SUBSYS. For information about this object, see “The SUBSYS Object” (page 38). This chapter
contains these sections:
• “Displaying Information” (page 40)
• “Using the PRIMARY SUBSYS Command” (page 41)
