NOTE: Allocating custom volumes in descending order of capacity optimizes custom volume allocation
during the Install CV process.
As defined in Table 14, VSC does not work with OPEN-L and OPEN-M emulation types. VSC supports
OPEN-3, OPEN-8, OPEN-9, OPEN-E, and OPEN-V emulations.
Table 15 lists specifications and the minimum and maximum volume capacities for mainframe and open
systems.
