CU (control unit) . The USP V/VM storage system supports a maximum of
256 logical CUs numbered sequentially from 00–FF. Each CU controls up to
256 LDEVs. LDEVs within the USP V/VM storage system are accessed by a
combination of CU number (00-FF) and device number (00–FF).
However, the CU number FF is reserved for the Command Control Interface
(CCI) operation. Therefore the CUs that can be used for the USP V/VM
program products operation are up to CU number FE. This means that the
number of CUs that can be used for the USP V/VM program products
operation are 255 per LDKC at the maximum.
The following table shows the example of the device numbers for CU.
