Installation 15

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.

16 HP StorageWorks Disk Array XP Operating System Configuration Guide: HP-UX
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

Installation 17
•(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.

18 HP StorageWorks Disk Array XP Operating System Configuration Guide: HP-UX
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
• Alternate link for I/O path failover (included in HP-UX)
• Logical volume management (included in HP-UX)

Installation 19
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 procedures
Perform these actions to install and configure the disk array:
1. Install and configure the disk array (see page 21)
•Setting the host mode for the disk array ports
•Setting the System Option Modes
•Configuring the Fibre Channel ports
2. Install and configure the host (see page 26)
•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 (see page 29)
•Defining the paths
•Verifying HBA installation
•Verifying device recognition
4. Configure disk array devices (see page 35)
•Verifying the device files and drivers
•Creating the device files
•Creating the physical volumes
•Creating new volume groups
•Creating logical volumes
•Creating the file systems
•Setting the I/O timeout parameter
•Creating the mount directories
•Mounting and verifying the file systems
•Setting and verifying the auto-mount parameters

Installation 21
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.

22 HP StorageWorks Disk Array XP Operating System Configuration Guide: HP-UX
For the XP1024/XP128 arrays, the host mode can also be set at the port
information window in Command View XP AE.
