Hitachi Lightning 9900™ V Series LUN Expansion and Virtual LVI/LUN User’s Guide 35
4.2.2 Creating VLL volumes
The Install VLL volume function allows you to define and install one or more Virtual LVI/LUN
volumes under an existing volume.
Note: The Install VLL volume Function allocates VLL volumes in the order in which the
function finds sufficient free space for the VLL volumes, so for optimum space allocation you
should allocate VLL volumes in descending order of capacity.
1. Change to Modify mode (refer to section 2.3 if you need instructions). Select the LUN
Expansion (LUSE)/Virtual LVI/LUN (VLL) button (
) to open the LUSE/VLL panel.
The LUSE tab is the default view (refer to Figure 3.1). Select the VLL tab (refer to
Figure 4.1)

pop-up menu (see Figure 4.7).

systems)
