HP StorageWorks Disk Array XP operating system configuration guide NonStop 7

8About this guide

1 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.
The HP NonStop operating system runs on HP S-series and Integrity NonStop servers to
provide continuous availability for applications, databases, and devices. The NonStop
OS and servers support high transaction volumes and complex mixed workloads. An
open application development environment supports common standards, including Java,
CORBA, SQL, OBDC, JDBC, HTTP, TCP/IP, and application programming interfaces.
Features and requirements
Ask your HP service representative about the latest supported hardware and software.
The disk arrayhasthefollowingfeatures:
•Storage capacity. The storage capacity for each model is listed below:
XP128: From8to128drivesforupto36TB,48FCports
XP1024: From8to1024drivesforupto149TB,64FCports
XP10000: Up to 240 drives for up to 69.2 TB, 48 FC ports
XP12000: Up to 1152 drives for up to 332 TB, 128 FC ports
•Server support. HP S-series and Integrity NonStop servers
•Operating system support. HP NonStop OS with the latest supported patches.
Before installing the disk array, ensure the environment conforms to these requirements:
•Fibre Channel ServerNet Adapters (FCSAs) Install FCSAs and all utilities and
drivers. Refer to the FCSA 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

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 LC connectors
•Direct connect (PriNL) or fabric switch connect (N-port or DFA)
•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-x 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-x
disk devices. For example, an OPEN-x LUSE volume created from ten OPEN-x
volumesisdesignatedasOPEN-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.
10 Installation

Failover
The NonStop system architecture, by default, provides two paths to each LDEV for
failover, and can be further enhanced with host mirroring.
SNMP configuration
The XP family of disk arrays supports standard Simple Network Management Protocol
(SNMP) as an aid for disk array management. The SNMP agent on the service processor
(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.
HP StorageWorks Disk Array XP operating system configuration guide NonStop 11

Installation procedures
Perform these actions to install and configure the disk array:
1. Install and configure the disk array
•Setting the System Option Modes
•Configuring the Fibre Channel ports
•Setting the host mode
2. Install and configure the host
•Loading the OS and software
•Installing and configuring the FCSAs
•Fabric zoning and LUN security
3. Connect the disk array
•Defining the paths
•Verifying disk array device recognition
4. Configure disk devices
12 Installation

Install and configure the disk array
The HP service representative performs these tasks:
•Assembling hardware and installing software
•Loading the microcode updates
•Installing and formatting devices
After these tasks are finished, you will use Remote Web Console XP, Command View XP,
Command View XP Advanced Edition, or LUN Configuration and Security Manager XP
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 System Option Modes
The NonStop servers have no operating system specificSystemOptionMode
requirements.
Configuring the Fibre Channel ports
Configure the disk array Fibre Channel ports by using Remote Web Console XP (shown),
Command View XP, or Command View XP Advanced Edition. 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.
HP StorageWorks Disk Array XP operating system configuration guide NonStop 13

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. For specificvalues,refertotheHP
StorageWorks LUN Configuration and Security Manager XP User Guide applicable
to your array .
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 figures and table. HP recommends that the individual
Fibre Channel paths from the NonStop host to the array be routed through separate FC
switches utilizing WWN zoning. See the HP StorageWorks SAN Design Reference
Guide at http://h18006.www1.hp.com/storage/saninfrastructure.html.
14 Installation

Fabric Parameter Connection Parameter Provides
ON FC-AL Not supported
ON Point-to-Point N-port (SAN fabric port)
OFF FC-AL NL-port (private arbitrated loop; direct
connect without a SAN)
OFF Point-to-Point Not supported
HP StorageWorks Disk Array XP operating system configuration guide NonStop 15

Setting the host mode for the disk array ports
After the disk array is installed, you must set the host mode for each disk array port to
match the host OS. Set the host mode using LUN Manager in Remote Web Console XP
(shown), Command View XP, or Command View XP Advanced Edition. If these are not
available, the HP service representative can set the host mode using the SVP.
The host mode setting for the NonStop OS is 0C.
Check with your HP service representative for the latest host mode settings.
16 Installation

For XP1024/XP128 arrays, you can also set the host mode at the port information
window in Command View XP AE.
Install and configure the host
This section explains how to install and configure the host and Fibre Channel ServerNet
Adapters (FCSAs) 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.
HP StorageWorks Disk Array XP operating system configuration guide NonStop 17

Installing and configuring the FCSAs
Install and configure the adapters using the Fibre Channel ServerNet Adapter
Installation and Support Guide, available at the NonStop Technical Library web site
http://h30163.www3.hp.com/ntl/.
Fabric zoning and LUN security for multiple operating systems
You can connect multiple clusters of various operating systems to the same switch using
appropriate switch zoning and array LUN security as follows:
•Use Secure Manager for LUN isolation when multiple NonStop systems connect
through a shared array port. Secure Manager provides LUN security by allowing
you to restrict which LUNs each host can access.
•Do not connect other operating systems to the same XP ports or even use a port
that shares a processor with the same port as NonStop systems.
•Use SAN switches dedicated to NonStop connections, or solutions that have
been qualified by HP.
Environment Fabric Zoning LUN Security
Single node SAN Not required Must be used
Multiple node SAN Not required Must be used
Connect the disk array
The HP service representative connects the disk array to the host by:
1. Verifying operational status of the disk array channel adapters, LDEVs, and paths.
2. Connecting the Fibre Channel cables between the disk array and the fabric switch
or host.
3. Verifying the ready status of the disk array and peripherals.
Defining the paths
Use Remote Web Console XP (shown), Command View XP, or Command View XP
Advanced Edition to define paths (LUNs) between hosts and volumes in the disk array.
For non-host mirrored disks, create two identical host groups on two different ports (one
port in each cluster in the array) with identical LUNs in each group. For host mirrored
disks, configure each of the Primary (P) and Mirrored (M) volumes as two identical
host groups on two different ports (one port in each cluster in the array) with identical
LUNs in each group..
This process is also called “LUN mapping.”
18 Installation

In Remote Web Console XP and Command View XP, LUN mapping includes:
•Configuring ports
•Enabling LUN security on the ports
•Creating host groups
•Assigning host bus adapter WWNs to host groups
•Mapping volumes to host groups (by assigning LUNs)
In Command View XP Advanced Edition, LUN mapping includes:
•Configuring ports
•Creating storage groups
•Mapping volumes and WWN/host access permissions to the storage groups
For details, see LUN Configuration and Security Manager XP User’s Guide or Command
View XP Advanced Edition Device Manager Web Client User’s Guide.
Record the LUNS and their ports, WWNs, nicknames, and LDEVs. This information will
be used later to verify host and device configuration.
HP StorageWorks Disk Array XP operating system configuration guide NonStop 19

Verifying disk arraydevicerecognition
For the NonStop host to recognize disk devices, the disk devices must first be configured
and started using the installation procedure described in chapter 2 of the Fibre Channel
ServerNet Adapter Installation and Support Guide (available at the NonStop Technical
Library web site http://h30163.www3.hp.com/ntl/).
Configure disk devices
Configure the disk array devices in the same way you would configure any new disk on
the host. Creating scripts to configure all devices at once may save you considerable
time.
Refer to Fibre ChannelServerNet Adapter Installation and Support Guide,atthe
NonStop Technical Library web site http://h30163.www3.hp.com/ntl/.Toconfigure
the array disk devices, use SCF commands including ADD, START, and INIT as detailed
in subsection DISK configuration (ESS Connection) of Chapter 2,Installing anFCSA.
