10 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 11

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. 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 StorageWo rks Command V iew XP with LUN management feature or Remote Control with LUN Configuration

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

Fibre Channel interface

Manager XP option. These are used to configure disk array ports and paths.

• (Recommended) HP StorageWorks Secur e Manager XP. Allows

the host to access only authorized array devices.

• (Optional) Other available XP software (some may not apply to 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 HP StorageWorks Cache LUN XP HP StorageWorks Auto Path XP HP StorageWorks Cluster Extension XP HP StorageWorks Performance Advisor XP

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 13

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 logical volume (storage) 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)

14 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) 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.

RAID Manager command devices

RAID Manager manages Business Copy (BC) and/or Continuous Access (CA) operations from a host server. To use RAID Manager with BC or CA, you use Command View or LUN Configuration Manager to designate at least one LDEV as a command device. Refer to the Command View or LUN Configuration Manager user guide for information about how to designate a command device.

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 V iew or LUN Co nfiguration Manager, 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 you must set depending on the host you use. Use Command View (shown) or LUN Configuration Manager to set the Host Mode for each port. The host mode setting for HP-UX is 08.

Installation 17

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

140 Optional None ON: Response to the Inquiry command is

OS version: HP-UX 11.0 and later.

ON: When the host scans the LUNS on the port, the disk array is not represented in the 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.

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

Configuring the Fibre Channel ports

Configure the Fibre Channel ports on the disk array using Command View (shown) or the Fibre Parameter window in LUN Configuration Manager. 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.

Installation 19

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 Referenc e Gu ide on the

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

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.

Installation 21

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.

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

Fabric zoning and LUN security for multiple operating systems

You can connect multiple clusters of various operating systems to the same switch and fabric using appropriate zoning and LUN security as follows:

• Host zones must contain only homogeneous operating systems.

• Storage port zones may overlap if more than one operating system needs to share an array port.

• Heterogeneous operating systems may share an XP array port if you use Secure Manager and set the appropriate host group and mode. All others must connect to a dedicated XP array port.

• Use Secure Manager for LUN isolation when multiple hosts connect through a shared array port. Secure Manager provides LUN security by allowing you to restrict which LUNs each host can access.

Installation 23

Connect the disk array

The HP service representative connects the disk array to the host by:

1. V erifying 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 Command View (shown) or LUN Configuration Manager to create paths (LUNs) between hosts and volumes in the disk array. This process is also called “LUN mapping.” LUN mapping includes:

• Configuring po rts

• Setting LUN security

• Creating host gro ups

• Assigning ho st bu s adap ter WWNs to host groups

• Mapping volumes to host groups (by assigning LUNs)

See the Command View or LUN Configuration Manager guide for more information. Note the LUNS and their ports, WWNs, nicknames, and LDEVs for later use in verifying host and device configuration.
