Table 1.3 Virtual Lvi/Lun Specifications - Hitachi 9900 V Series User Manual

Table 1.3 lists the Virtual LVI/LUN specifications, and Table 1.4 lists the minimum and
maximum Virtual LVI/LUN volume capacities for open systems. Each Virtual LVI/LUN volume
has its own assigned unit control block (UCB), and multiple LVI/LUN types can be configured
within each Virtual LVI/LUN volume, so long as the device type is from the same device
family (e.g. all open volumes, or all 3390s). Open and 3390 volumes are not allowed in the
same parity group because they have different formats.
