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.

14 HP StorageWorks Disk Array XP Operating System Configuration Guide: OpenVMS
Features and requirements
The disk array and host have 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. PCI-based AlphaServers
•Operating system support. OpenVMS 7.3 or later
Before installing the disk array, ensure the environment conforms to these
requirements:
• Alpha System Firmware version 5.6 or higher for Fibre Channel
support.
• 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 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.
• 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

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

16 HP StorageWorks Disk Array XP Operating System Configuration Guide: OpenVMS
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.
RAID Manager command devices
HP’s RAID Manager optional software product manages Business Copy
(BC) or Continuous Access (CA) operations from a host server. To use
RAID Manager with BC or CA, use Command View or LUN
Configuration Manager to designate at least one disk array LDEV as a Raid
Manager command device. Refer to the Command View or LUN
Configuration Manager user guide for information about how to designate a
command device.
On the OS side, you should create a LUN 0 device of 35 megabytes (the
smallest allowed). This will allow you to use host-based RAID
management tools available from HP and will also allow HP support to do
some additional diagnostics.
Note that storage assigned to the LUN 0 device is not accessible from
OpenVMS.
Failover
The XP family of disk arrays supports many standard software products,
including Open VMS Multipath Software, that provide host, application, or
I/O path failover and logical volume (storage) management.

Installation 17
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.

18 HP StorageWorks Disk Array XP Operating System Configuration Guide: OpenVMS
Installation procedures
Perform these actions to set up the disk array:
1. Install and configure the disk array (page 19)
• Setting the System Option Modes
• Configuring the Fibre Channel ports
2. Install and configure the host (page 24)
• Loading the OS and software
• Installing and configuring the HBAs
• Clustering and fabric zoning
3. Configure FC switches (page 27)
• Defining the paths
4. Connect the disk array (page 29)
• Verifying disk array device recognition
5. Configure disk array devices (page 30)
• Initializing and label the devices
• Mounting the devices
• Verifying file system operation

Installation 19
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.
The following restrictions apply when configuring any XP disk array with
an OVMS host:
• When an XP port is assigned to OpenVMS, that port may not be
shared with any other operating system.
• Multiple OpenVMS hosts may share the same XP port.
• Sharing of CHA microprocessors is not recommended.

20 HP StorageWorks Disk Array XP Operating System Configuration Guide: OpenVMS
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.
Mode Level Description and Usage
161 Mandatory Allows high-speed microprocessor FW update.
228 Mandatory Provides unique UUIDs to the boot device, which
allows the SRM console WWIDMGRquickset to
discover multiple boot paths.
278 Mandatory RCSN notification that allows new XP128 ports to
be used/identified when adding to an existing
configuration.
