The dcus_available property is a read-only property. Its values depend on the current assignment of DCUs and on the DCUs listed in the dcus_assignable property. Only DCUs listed as available can be assigned to a host. If a DCU is assigned to a host, it does not appear in the list of available DCUs. Also, if you changed the dcus_assignable property to exclude a specific DCU, that DCU does not appear in the list of available DCUs, even if it is not assigned to another host, until you change the dcus_assignable property.
This task uses PDomain_0, DCU2, DCU3 as examples.
This example shows that only DCU2 and DCU3 are available for assignment to the host in PDomain_0.
