Installing the Hardware
Initial installation of the URz hardware is performed by the user and the Hitachi representative. To install the hardware required for URz operations:
1.User: Identify the locations of the URz primary and secondary data volumes (primary data volumes and secondary data volumes), so that the URz hardware can be installed and configured properly.
2.User and Hitachi Representative: Make sure that the primary storage system(s) and secondary storage system(s) are configured for USP V Storage Navigator operations (e.g., SVP connected to LAN). Refer to the Storage Navigator User’s Guide for information and instructions on setting up Storage Navigator operations.
3.Hitachi Representative: Make sure that the primary storage systems and secondary storage systems are properly configured for URz operations (e.g., cache, NVS) (see section Cache and Nonvolatile Storage (NVS)). Make sure that the desired system option modes are enabled (see Table
4.Hitachi Representative: Make sure the primary storage systems are configured to report sense information to the host(s). The secondary storage systems should also be attached to a host server to enable reporting of sense information in case of a problem with an secondary data volume or secondary storage system. If the remote site is unattended, the secondary storage systems should be attached to a host server at the primary site, so that the system administrator can monitor the operational condition of the secondary storage systems.
5.Hitachi Representative: If power sequence control cables are used, set the power select switch for the cluster to LOCAL to prevent the primary storage system from being powered off by the host. Also make sure the secondary storage system will not be powered off during URz operations. See Setting up Remote Copy Connections for further information on powering off/on the primary storage systems and secondary storage systems.
6.Hitachi Representative: Install the URz remote copy connections between the primary storage system(s) and secondary storage system(s). This hardware (optical fibre cables, switches, etc.) is supplied by the user.
See section Setting up Remote Copy Connections for remote copy configurations. Distribute the paths between different storage clusters and switches to provide maximum flexibility and availability. The logical paths between the primary storage system and secondary storage system must be separate from the logical paths between the host and secondary storage system.
