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.  
Installation  
15  
   
Features and requirements  
Ask your HP service representative about the latest supported hardware and  
software.  
The disk array and host have the following features:  
Storage capacity. The storage capacity for each model is listed  
below:  
XP128: From 8 to 128 drives for up to 18 TB, 48 FC ports  
XP1024: From 8 to 1024 drives for up to 149 TB, 64 FC ports  
XP10000: Up to 240 drives for up to 69.2 TB, 48 FC ports  
XP12000: Up to 1152 drives for up to 165 TB, 128 FC ports  
Server support. HP-UX-supported processor  
Operating system support. HP-UX, version 10.20, 11.0, or 11i v2  
with the latest patches (if any)  
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 Remote Web Console XP,  
Command View XP Advanced Edition or Command View XP with  
LUN management feature for configuring disk array ports and  
paths  
(Recommended) HP StorageWorks LUN Configuration and  
Security Manager XP  
16  
HP StorageWorks Disk Array XP Operating System Configuration Guide: HP-UX  
                 
(Optional) Other available XP software (some may not be  
supported by your array:  
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  
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.  
Installation  
17  
                             
Device emulation types  
The XP family of disk arrays supports these device emulation types:  
OPEN-K/3/8/9/E devices: 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-K/3/8/9/E disk 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 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 management.  
The following are supported for HP-UX:  
• HP Multi-Computer/ServiceGuard (MC/ServiceGuard) software for  
application failover  
• Logical volume management (included in HP-UX)  
18  
HP StorageWorks Disk Array XP Operating System Configuration Guide: HP-UX  
       
SNMP configuration  
The XP family of disk arrays supports standard Simple Network  
Management Protocol (SNMP) for remotely managing the disk array. The  
SNMP agent on the SVP performs error-reporting operations requested by  
the SNMP manager. SNMP properties are usually set from the SVP but  
they can also be set remotely using Remote Web Console XP, Command  
View XP, or Command View XP Advanced Edition. Refer to the  
applicable user’s guide for procedures.  
RAID Manager command devices  
RAID Manager manages Business Copy (BC) or Continuous Access (CA)  
operations from a host server. To use RAID Manager with BC or CA, you  
use Remote Web Console, Command View, or Command View XP  
Advanced Edition to designate at least one LDEV as a command device.  
Refer to the applicable user’s guide for information about how to designate  
a command device.  
Installation

Installation procedures  
• Setting the host mode for the disk array ports  
• Installing and configuring the HBAs  
• Fabric zoning and LUN security for multiple operating systems  
• Defining the paths  
• Setting the I/O timeout parameter  
• Creating the mount directories  
• Setting and verifying the auto-mount parameters

HP StorageWorks Disk Array XP Operating System Configuration Guide: HP-UX  
   
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 Remote Web Console,  
Command View, Command View XP Advanced Edition, or LUN  
Configuration and Security Manager to complete the remaining tasks listed  
below. If you do not have these programs, your HP service representative  
can perform these tasks for you.  
Setting the host mode for the disk array ports  
The disk array ports have host modes that must be set depending on the  
host you use. After the disk array is installed use LUN Manager in Remote  
Web Console XP (shown), Command View XP, or Command View XP  
Advanced Edition to set the host mode for each port. The host mode setting  
for HP-UX is 08.  
Installation  
21  
         
For the XP1024/XP128 arrays, the host mode can also be set at the port  
information window in Command View XP AE.

device list for HP-UX.  
OFF: When the host scans the LUNS on the  
port, the disk array is represented in the device  
list for HP-UX.  
Installation  
23  
   
Configuring the Fibre Channel ports  
Configure the disk array Fibre Channel ports by using Remote Web  
Console (shown), Command View, or Command View XP AE. 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, set the port addresses by selecting a unique  
arbitrated loop physical address (AL-PA) or loop ID for each port.
