The PI_LDTC record stores the performance data indicating the performance of an internal, external, or virtual volume (data of remote copy by TrueCopy or TrueCopy for Mainframe, and monitoring data for global-active device).
If the CU number of the target LDEV is not set to be monitored, the record will not be created.
