Installation 9

Installation
Installation of the HP StorageWorks Disk Array XP is performed by your
HP service representative and you. The HP service representative installs
the disk array and formats the disk devices. You configure the host server
for the new devices with assistance from the HP service representative.

10 HP StorageWorks Disk Array XP Operating System Configuration Guide: DYNIX/ptx
Features and requirements
The disk array and host have the following features and requirements.
• HP StorageWorks disk arrays:
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
• IBM NUMA-Q series enterprise system
• DYNIX/ptx operating system
• Host Bus Adapters (HBAs): Install adapters 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 for configuring disk array ports and paths.
•(Recommended) HP StorageWorks Secure Manager XP: Allows the
host to access only array devices for which it is authorized.
• Other available XP Software (some may not apply to 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
HP StorageWorks Auto Path XP
HP StorageWorks Cluster Extension XP
HP StorageWorks Performance Advisor XP software

Installation 11
Fibre Channel interface
The XP48, XP128, XP512, and XP1024 disk arrays support these 1 Gbps
and 2 Gbps Fibre Channel interfaces:
• 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 fabric direct 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 disk arrays support the following 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)
allows you to 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 CVS 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
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.

12 HP StorageWorks Disk Array XP Operating System Configuration Guide: DYNIX/ptx
Failover
The disk arrays support many standard software products that provide host,
application, or I/O path failover and logical volume (storage) management.
SNMP configuration
The disk arrays support standard Simple Network Management Protocol
(SNMP) for remotely managing 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. To configure the SNMP
manager on the host, refer to the operating system documentation.
RAID Manager command devices
RAID Manager manages Business Copy (BC) and/or Continuous
Access (CA) operations from a server host. To use RAID Manager
with BC or CA, you must 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.

Installation 13
Installation procedures
The HP representative and you perform the following procedures:
1. “Install and configure the disk array” on page 14
• 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” on page 18
• 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” on page 21
• Defining the paths
• Verifying disk array device recognition
4. “Configure disk array devices” on page 24

14 HP StorageWorks Disk Array XP Operating System Configuration Guide: DYNIX/ptx
Install and configure the disk array
The HP service representative performs the following tasks:
• Assembling hardware and installing software
• Loading the microcode updates
• Installing the channel adapters (CHAs) and cabling
• Installing and formatting devices
You perform the additional tasks 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 representative sets the System Option Mode(s) based on the
operating system and software configuration of the host.

Installation 15
Configuring the Fibre Channel ports
Configure the disk array Fibre Channel ports by using Command View
(shown) or the Fibre Parameter window in LUN Configuration Manager.
Select the settings for each port based on your storage area network
topology. 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, you set the port addresses by selecting a
unique arbitrated loop physical address (AL-PA) or loop ID for each port.

16 HP StorageWorks Disk Array XP Operating System Configuration Guide: DYNIX/ptx
Fabric and Connection parameter settings
You can 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.
Fabric
Parameter
Connection
Parameter Provides
ON FC-AL Not supported
ON Point-to-Point N-port (SAN fabric port)
OFF FC-AL Not supported
OFF Point-to-Point Not supported

Installation 17
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 DYNIX/ptx is 04.

18 HP StorageWorks Disk Array XP Operating System Configuration Guide: DYNIX/ptx
Install and configure the host
Install and configure the host and host bus adapters (HBAs) that connect
the host to the disk array.
Loading the OS and software
Follow the manufacturer’s instructions to load the operating system and
software onto the host. Load all OS patches and configuration utilities
supported by HP and the HBA manufacturer.
Installing and configuring the HBAs
Install and configure the host bus adapters using the HBA manufacturer’s
instructions.
