For OPEN-V volumes, there are four ways to create CVS volumes ( Table 22 ). 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.
Table 23 lists the CVS specifications and the minimum and maximum CVS volume capacities for
mainframe and open systems.
Table 22 Creating CVS volumes using Install CV (for OPEN-V)
Install CV method Description
Specify size and number Used to specify the capacity and number of CVs in the CVS volume you want
to create.
Divide free space by number Used to create CVS volumes by specifying the number of CVs in the CVS
volume to be created.
Divide free space by size Used to create CVS volumes by specifying the capacity of CVs in the CVS
volume to be created.
Set remaining space as volume Used to create a CVS volume using the remaining space on the VDEV.
