You can perform TrueCopy operations using one of the following user interfaces:
- Hitachi Device Manager - Storage Navigator (HDvM - SN) is a browser-based graphical user interface (GUI) that allows you to perform
TrueCopy operations from any LAN-attached computer.
- The primary storage system must be LAN-attached to a Device Manager - Storage Navigator computer.
- For disaster recovery purposes, the secondary storage system must be LAN-attached to a separate Device Manager - Storage Navigator computer at the secondary site so that you can perform operations on the secondary storage system in the event that the primary site is not available.
- When you use virtual storage machine volumes, the physical LDEV ID, serial number, and the virtual information for the storage system are displayed on Device Manager - Storage Navigator. However, you cannot add remote connections by specifying the serial number of the virtual storage machine or create pairs by specifying the virtual LDEV ID. When you perform TrueCopy operations using Device Manager - Storage Navigator, specify the physical LDEV ID and serial number of the storage system.
- Command Control Interface (CCI) is a command-line interface that allows you to perform TrueCopy operations by issuing commands to the storage system either from a client or server through the host Fibre Channel interface (in-band method) or from a LAN-attached computer (out-of-band method). CCI provides a scripting capability that enables you to automate replication operations. CCI is required for performing failover operations.
- When you use, for a TrueCopy pair, a volume connected to a host by using NVMe-oF, you can use only CCI to create the TrueCopy pair. You can use HDvM - SN for other operations.
