Hitachi TrueCopy Local Commands
Figure 2.7 illustrates a Hitachi TrueCopy local configuration. The TrueCopy local commands
support a function which links the system operation for the purpose of volume backup among
UNIX servers with the operation management of the server system. The TrueCopy local
commands perform the same functions as the remote commands only within the same
storage system instead of between two storage systems.
