Figure 3-7 LDEV grouping for USP V/VM and earlier
For Virtual Storage Platform and later, CCI can be used to create a group of
multiple LDEVs by defining device groups. This is accomplished by defining
device groups in either the primary or secondary configuration definition file,
but not both. By defining a device group, LDEV information can be changed
or defined in one operation. It is not required to modify LDEV information in
both configuration definition files. For example, referencing LDEVs or creating
pools can be executed at the same time, because all LDEVs in the device
group are subjected to the operation.
