Installation
You and your HP service representative each play a role in installation.
Your HP service representative is responsible for installing the disk array
and formatting the disk devices. You are responsible for configuring the
host server for the new devices with assistance from your HP service
representative.

12 HP StorageWorks Disk Array XP Operating System Configuration Guide: SGI IRIX
Features and requirements
The disk array has the following features:
•Storage capacity. The storage capacity for each model is listed below:
XP48: Up to 48 drives from 72 GB to 8.7 TB, 24 FC ports
XP128: From 8 to 128 drives for up to 18 TB, 48 FC ports
XP512: Up to 512 drives from 72 GB to 93 TB, 48 FC ports
XP1024: From 8 to 1024 drives for up to 149 TB, 64 FC ports
XP12000: Up to 1152 drives for up to 165 TB, 128 FC ports
•Server support. SGI ORIGIN 2000 system(s)
•Operating system support. SGI IRIX operating system 6.5 or higher
with current patches.
Before installing the disk array, ensure the environment conforms to these
requirements:
•Host Bus Adapters (HBAs). Install HBAs and all utilities and
drivers. Refer to the adapter documentation for installation details.
•(Recommended) HP StorageWorks Command View XP with LUN
management feature or Remote Control with the LUN Configuration
Manager XP option. These are used to configure disk array ports and
paths.
•(Recommended) HP StorageWorks Secure Manager XP. Allows the
host to access only authorized array devices.
•(Optional) Other available XP software (some may not be supported
by your system):
HP StorageWorks Business Copy XP
HP StorageWorks Continuous Access XP
HP StorageWorks Continuous Access Extension XP
HP StorageWorks Auto LUN XP
HP StorageWorks Data Exchange XP
HP StorageWorks Resource Manager XP
HP StorageWorks RAID Manager XP
HP StorageWorks Cache LUN XP

Fibre Channel interface
The XP family of disk arrays supports these Fibre Channel elements:
• Connection speed of 1 Gbps and 2 Gbps
• Short-wave non-OFC (open fiber control) optical interface
• Multimode optical cables with SC or LC connectors
• Public or private arbitrated loop (FC-AL) or direct fabric attach
• Fibre Channel switches
Even though the interface is Fibre Channel, this guide uses the term “SCSI
disk” because disk array devices are defined to the host as SCSI disks.
Device emulation types
The XP family of disk arrays supports these device emulation types:
•OPEN-xdevices: OPEN-x logical units represent disk devices.
Except for OPEN-V, these devices are based on fixed sizes. OPEN-V
is a user-defined size. Supported emulations include OPEN-3,
OPEN-8, OPEN-9, OPEN-E, OPEN-L, and OPEN-V devices.
•LUSE devices (OPEN-x*n): Logical Unit Size Expansion (LUSE)
devices combine 2 to 36 OPEN-x devices to create expanded LDEVs
larger than standard OPEN-xdisk devices. For example, an OPEN-x
LUSE volume created from ten OPEN-x volumes is designated as
OPEN-x*10.
•CVS devices (OPEN-x CVS): Volume Size Configuration (VSC)
defines custom volumes (CVS) that are smaller than normal
fixed-sized logical disk devices (volumes). (OPEN-V is a CVS-based
custom disk size that you determine. OPEN-L does not support CVS.)
• LUSE (expanded) CVS devices (OPEN-x*n CVS): LUSE CVS
combines CVS devices to create an expanded device. This is done by

14 HP StorageWorks Disk Array XP Operating System Configuration Guide: SGI IRIX
first creating CVS custom-sized devices and then using LUSE to
combine from 2 to 36 CVS devices. For example, if three OPEN-9
CVS volumes are combined to create an expanded device, this device
is designated as OPEN-9*3-CVS.
Failover
The XP family of disk arrays supports many standard software products
that provide host, application, or I/O path failover and logical volume
(storage) management.
SNMP configuration
The XP family of disk arrays supports standard Simple Network
Management Protocol (SNMP) to remotely manage the disk array from the
host. The SNMP agent on the remote console PC or Command View can
provide status and Remote Service Information Message (R-SIM) reporting
to the SNMP manager on the host for up to eight disk arrays. Refer to the
operating system documentation to configure the SNMP manager on the
host.

Installation 15
RAID Manager command devices
RAID Manager manages Business Copy (BC) and Continuous Access
(CA) operations from a host server. To use RAID Manager with BC or CA,
you use Command View or LUN Configuration Manager to designate at
least one LDEV as a command device. Refer to the Command View or
LUN Configuration Manager user guide for information about how to
designate a command device.

16 HP StorageWorks Disk Array XP Operating System Configuration Guide: SGI IRIX
Installation procedures
Perform these actions to install and configure the disk array:
1. Install and configure the disk array (page 17)
• Setting the System Option Modes
• Configuring the Fibre Channel ports
• Setting the Host Mode for the disk array ports
2. Install and configure the host (page 21)
• Loading the OS and software
• Installing and configuring the HBAs
• Clustering and fabric zoning
• Fabric zoning and LUN security for multiple operating systems
3. Connect the disk array (page 24)
• Defining the paths
• Verifying new device recognition
4. Configure disk array devices (page 26)
• Creating device files
• Partitioning and labeling the devices
• Enabling command tag queuing
• Creating the file systems
• Creating and verifying the mount directories
• Registering, mounting, and verifying the file systems

Installation 17
Install and configure the disk array
The HP service representative performs these tasks:
• Assembling hardware and installing software
• Loading the microcode updates
• Installing the channel adapters (CHAs) and cabling
• Installing and formatting devices
After these tasks are finished, you will use Command View or LUN
Configuration Manager to complete the remaining tasks listed below. If you
do not have Command View or LUN Configuration Manager, your HP
service representative can perform these tasks for you.
Setting the System Option Modes
The HP service representative sets the System Option Mode(s) based on the
operating system and software configuration of the host.

18 HP StorageWorks Disk Array XP Operating System Configuration Guide: SGI IRIX
Configuring the Fibre Channel ports
Configure the Fibre Channel ports on the disk array using Command View
(shown) or the Fibre Parameter window in LUN Configuration Manager.
Select the settings for each port based onthe device to which the port is
connected (fabric switch or point-to-point connection). Use switch zoning
if you connect different types of hosts to the array through the same switch.
Fibre Address
In fabric environments, the port addresses are assigned automatically. In
arbitrated loop environments, set the port addresses by selecting a unique
arbitrated loop physical address (AL-PA) or loop ID for each port.

Installation 19
Fabric and Connection parameter settings
Set each array port to FABRIC ON or OFF with connections of
POINT-TO-POINT or FC-AL as shown in the following table and figures.
For detailed topology information, refer to the HP StorageWorks SAN
Design Reference Guide on the
hp.com website.

Setting the Host Mode for the disk array ports
The disk array ports have Host Modes that you must set depending on the
host you use. After the disk array is installed, use Command View (shown)
or LUN Configuration Manager to set the Host Mode for each port.
The host mode setting for SGI IRIX is 00.
