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.
