For OPEN-V volumes, there are four ways to create CVS volumes (
). You can specify from 46 MB
(50 cylinders) up to the VDEV’s maximum capacity for a CVS volume’s capacity.
NOTE:
CVS functions are not available for OPEN-L and OPEN-M volumes.
NOTE:
The install CV function allocates CVS volumes in the order in which the function finds sufficient
free space for the CVS volumes. For optimum space allocation, allocate CVS volumes in descending order
of capacity.
lists the CVS specifications and the minimum and maximum CVS volume capacities for
mainframe and open systems.
