TrueCopy for z/OS user guide 61
TC390 supports concurrent operations with the following data management functions:
• Virtual LVI/LUN. Virtual LVI/LUN volumes can be assigned to TC390 pairs as long as the R-VOL has the
same or larger capacity than the M-VOL. If you need to perform Virtual LVI/LUN operations on an
existing TC390 M-VOL or R-VOL, you must delete the pair first to return the volume to simplex status. For
further information on Virtual LVI/LUN, please refer to the LUN Expansion (LUSE)/Virtual LVI/LUN (VLL)
User's Guide.
• Cache LUN XP. Cache LUN XP volumes can be assigned to TC390 pairs and Cache LUN XP operations
can be performed on TC390 M-VOLs and R-VOLs.

subsystem, TCzA pairs, TCA pairs and Universal Replicator pairs cannot be mixed in one consistency group.
If TCA pair has been allocated to Consistency group No. 00, TCzA pair and Universal Replicator pair
cannot be allocated to Consistency group No. 00. TCzA and TCA share the same cache sidefile area.
