Figure 25
Required license capacity for LUN Security XP Extension when using cascade
function
In Figure 25, VMAs are set to cascaded pairs' volumes. Before copying, the root volume's access
attribute is Read Only, the node and leaf's access attribute is Read/Write. When copy operations,
such as update copy or pairresync, are performed on these cascaded pairs, the root volume's access
attribu
te is copied to the node and leaf volumes. Therefore, to set the access attribute for volumes used in
cascade pairs, LUN Security XP Extension needs license capacity for the root volume and the node and
leaf volumes. If you set the access attribute to the root, node, or leaf volume, LUN Security XP Extension
requir
es license capacity for the root, node, and leaf volumes.
NOTE:
If LUN Security XP Extension's license capacity is insufficient, you might not able to create BC pairs. For
more information about LUN Security XP Extension's license capacity, see the
HP StorageWorks LUN
Security XP Extension user guide
