Preparing For The Usp V Installation; Hardware Installation Considerations - Hitachi Universal Storage Platform V Configuration Manual

Preparing for the USP V Installation

The following sections describe pre-installation considerations to follow before
installing the USP V.

Hardware Installation Considerations

The Hitachi Data Systems representative performs the hardware installation by
following the precautions and procedures in the USP V Maintenance Manual.
The USP V comes with all the hardware and cabling required for the
installation.
Hardware installation activities include:
•
Assembling all hardware and cabling
•
Installing and formatting the logical devices (LDEVs). Be sure to obtain the
desired LDEV configuration information from the user, including the desired
number of OPEN-x, LUSE, VLL, VLL LUSE, and multiplatform (FX) devices.
•
Installing the fibre-channel HBAs and cabling. The total fibre cable length
attached to each fibre-channel adapter must not exceed 500 meters (1,640
feet).
– Do not connect any OFC-type connectors to the USP V system.
– Do not connect/disconnect fibre-channel cabling that is being actively
used for I/O. This can cause the SGI IRIX system to hang.
– Always confirm that the devices on the fibre cable are offline before
connecting/disconnecting the fibre cable.
•
Configuring the fibre port topology. The fibre topology parameters for each
USP V fibre-channel port depend on the type of device to which the port is
connected, and the type of port. Determine the topology parameters
supported by the device, and set your topology accordingly (see
Configuring the USP V Fibre-Channel
Before starting the installation, check all specifications to ensure proper
installation and configuration.
