• Boundary values of external LUs are always one kilobyte, regardless of RAID levels.
NOTE:
• The xx is a variable indicating one or more numbers or letters.
• Slot capacity is expressed in kilobytes.
Volume Initialize and Make Volume functions
You can initialize a CVS volume using one of the following functions: Volume Initialize or Make Volume.
The Volume Initialize operation de-installs all variable-sized volumes under a CVS volume, and reformats
the CVS volume as a normal volume (FV). You must assign CU and LDEV numbers to the new formatted
FV. Any existing FVs on the original VDEV are not reformatted.
The Make Volume operation deletes all volumes in a VDEV, and creates new variable-sized volumes (CVs)
according to the specified settings. You can specify the following settings (see Table 30).
The following are the restrictions on CVs for the Volume Initialize function (other than OPEN-V):
• The CV must not be path-defined (including TrueCopy for z/OS, Continuous Access XP, ShadowImage
for z/OS, Business Copy XP, and Continuous Access XP Journal pair volumes).
• The CV must not be a component of a LUSE volume.
• The CV must not be reserved for Auto LUN XP.
• The CV must be read/write-enabled.
• The CV must not be a pool volume (pool-VOL)
• The CV must not be a journal volume.
• The CV must not be remote command device.
• The CV must not contain extents.
The following are the restrictions on CVs for the Make Volume function:
Table 29 Slot capacities

3390-xx 58
OPEN-xx (except for OPEN-V) 48

No. Setting CVS volumes to be created
1 Specify the capacity and number of
variable-sized volumes (CVs) under a
CVS volume.
A CVS volume that has the specified number of CVs of the specified
capacity is created. This is the same as the Install CV operation.
2 Specify the number of variable-sized
volumes (CVs).
A CVS volume that has the specified number of CVs is created (the
VDEV is divided by the specified number).
3 Specify the capacity of a
variable-sized volume (CV).
A CVS volume that has CVs of the specified capacity is created (the
VDEV is divided by the specified capacity).
4 Specify the remaining capacity for a
CVS volume.
If some space remains in the VDEV after CVS volumes are created
by settings 1through 3, that remaining space can also be converted
into a CVS volume.
