Hitachi TrueCopy® User Guide for Hitachi Virtual Storage Platform Gx00 and Fx00 Models
• Must be installed on the primary and secondary systems.
• Separate license codes are required for each storage system.
• Synchronous only. TrueCopy Asynchronous is not supported.
None.
When combining TrueCopy and Dynamic Provisioning, the following
licensed capacity limitations apply:
• If using a Dynamic Provisioning V-VOL (virtual volume) for the
TrueCopy P-VOL or S-VOL, the capacity of the allocated pages
for the DP-VOL will be counted as the licensed capacity of
TrueCopy.
• If the actual licensed capacity exceeds the available licensed
capacity, TrueCopy can be used as usual for 30 days. After 30
days, only split or release operations will be allowed.
• VSP G200:
You can use TrueCopy only with control memory in the basic
part. Adding control memory expands the capacity of the pairs
being created.
• VSP G400, G600, G800 and VSP F400, F600, F800:
Additional control memory is a prerequisite in both the primary
and secondary systems to use TrueCopy.
For information on adding control memory and setting the TC-
dedicated area, contact Hitachi Data Systems customer support.
