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

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 represent ative about the lat est supporte d 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 V iew XP Advanc ed Editi on 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

Fibre Channel interface

The XP fami ly of disk arrays support s these Fibre Channel elements:

• (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

• 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 Chan nel switches

Even though the interface is Fibre Chann el, this gui de 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 dete rmine. 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 expande d 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-C omputer/Serv iceGuard (MC/ServiceGuard) software for application failover

• Alternate link for I/O path failover (included in HP-UX)

• 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 app li cab le user’s guide f or information about how t o designate a command device.

Installation 19

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

Install and configure the disk array

The HP service represen tative perf orms these ta sks:

• 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 Securi ty Man ager to complete the remai ning t asks li sted 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 t he host mode f or e ach por t. The host mode se ttin g 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.

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

Setting the System Option Modes

ON: When the host scans the LUNS on the port, the disk a rray is not represen ted in the device list for HP-UX.

OFF: When the host scans the LUNS on the port, the disk array is represented in the d ev ice 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.

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

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 table and figures. For detailed topology information, refer to the HP StorageWorks SAN Design Reference Guide on the

hp.com

website.

Installation 25

Install and configure the host

This section explains how to 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.

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

Clustering and fabric zoning

If you plan to use clustering, install and configure the clustering software on the servers.

Clustering is the organization of multiple servers into groups. Within a cluster, each server is a node. Multiple clusters compose a multi-cluster environment. The following example shows a multi-cluster environment with three clusters, each containing two nodes. The nodes share access to the disk array.

Within the Storage Area Network (SAN), the clusters may be homogeneous (all the same operating system) or they may be heterogeneous (mixed operating systems). How you configure LUN Security and fabric zoning depends on the operating system mix and the SAN configuration.
