About This Manual

This manual describes the requirements and procedures for connecting the XP family

of disk arrays to an SGI system, and configuring the new disk array for operation with

the SGI IRIX operating system.

Installation of the HP Surestore Disk Array XP is performed by users with

administrator privileges and the HP service representative. The HP service

representative performs the physical installation of the disk array and formats the disk

devices. The user configures the system for the new devices with assistance as needed

from the HP service representative.

The HP account representative can assist in determining the supported configurations

for your system.

SGI IRIX INSTALLATION

The disk array comes with all hardware and cabling required for installation.

Installation of the disk array includes these activities:

• hardware installation

• remote console and LUN Configuration Manager installation

Hardware Installation

The HP service representative performs hardware installation as specified in the disk

array maintenance manual. Follow all precautions and procedures in the disk array

maintenance manual. Check all specifications to ensure proper installation and

configuration. Hardware installation involves several tasks:

1. Assemble all hardware and cabling.

2. Load the latest microcode and service processor (SVP) updates for full Fibre

Channel support.

3. Install and format the logical devices (LDEVs) using the SVP.

Make sure to get the desired LDEV configuration information from the user,

including the desired number of OPEN-K/3/8/9/E, CVS, LUSE, and

multiplatform (Data Exchange) devices.

Caution The SGI IRIX system can only recognize up to 32 LUs (per port). Make sure to

determine the number of disk array LUs based on this restriction.

4. Install the Fibre Channel adapters and cabling.

The total Fibre Channel cable length attached to each Fibre Channel adapter must

not exceed 500 meters (1,640 feet). Do not connect any open fibre control (OFC)

type connector to the disk array. Do not connect or 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 Channel cable are offline

before connecting or disconnecting the cable.

Fabric

Connect the disk array port to the F-port of the fabric switch. Connect the host adapter

to the FL-port of the fabric switch.

Disk Array FC Port

The Fibre Channel topology parameters for each disk array Fibre Channel port depend

on the type of device to which the disk array port is connected. Determine the topology

parameters supported by the device, and set your topology accordingly. The type of

disk array port is also important. See “Configuring the Disk Array Fibre Channel

Ports” (page 16).

Remote Console PC and LUN Configuration Manager Installation

The user or HP service representative can install the remote console PC and HP

Surestore LUN Configuration Manager XP. You will use the LUN Configuration

Manager software on the remote console PC to set the host modes for the disk array

ports and configure the Fibre Channel ports. For instructions on installing the LUN

Configuration Manager software, see the product manual:

HP Surestore LUN Configuration Manager XP: User’s Guide

If the LUN Configuration Manager software is not installed, the HP service

representative can use the SVP of the disk array to configure Fibre Channel ports.

Please contact your HP account team for further information on Fibre Channel

configuration services.
