About this guide This guide provides information about: • Requirements and procedures for connecting an XP disk array to a NonStop host system • Configuring the disk array for use with the NonStop operating system Intended audience This guide is intended for system administrators with knowledge of: • The host hardware • NonStop operating system • XP disk arrays Related documentation The following documents provide related information: • • • • • • • • • HP StorageWorks HP StorageWorks HP StorageWorks HP S

Conventions for storage capacity values Use the following values to calculate physical storage capacity (hard disk drives) for HP XP storage systems: • 1 KB (kilobyte) = 1,000 bytes • 1 MB (megabyte) = 1,0002 bytes • 1 GB (gigabyte) = 1,0003 bytes • 1 TB (terabyte) = 1,0004 bytes Use the following values to calculate logical storage capacity (logical devices) for HP XP storage systems: • 1 KB (kilobyte) = 1,024 bytes • 1 MB (megabyte) = 1,0242 bytes • 1 GB (gigabyte) = 1,0243 bytes • 1 TB (terabyte) = 1,024

1 Installing and configuring NonStop for the XP disk array 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.
• 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.
Figure 1 SNMP Configuration Installation roadmap Perform these actions to install and configure the disk array: 1. Install and configure the disk array 2. • Setting the host mode and host group mode • Setting the System Option Modes • Configuring the Fibre Channel ports Install and configure the host 3. • Loading the operating system and software • Installing and configuring the FCSAs • Fabric zoning and LUN security Connect the disk array 4.
CAUTION: The correct host mode must be set for all new installations (newly connected ports) to NonStop hosts. Do not select a mode other than 0C or 2C for NonStop. Changing a host mode after the host has been connected is disruptive and requires the server to be rebooted. When a new host group is added, additional host group modes (options) may be configured. The storage administrator must verify if an additional host group mode is required for the host group.
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 specific values, refer to the HP StorageWorks XP LUN Manager User's 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.

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/.
In XP Remote Web Console and XP Command View, 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 HP StorageWorks XP LUN Manager User's Guide or Command View XP Adv
To configure the array disk devices, use SCF commands including ADD, START, and INIT as detailed in subsection DISK configuration (ESS Connection) of Chapter 2, Installing an FCSA.

B Disk array supported emulations This appendix provides information about disk array supported emulations and emulation specifications. Some parameters may not be relevant to your array. Consult your HP representative for information about supported configurations for your system.
Note 1: The availability of an emulation depends on the disk array. Note 2: Open-V is a variable device type. The maximum configurable LDEV size depends on the RAID level and size of physical disks configured in the array. The minimum size is 46 MB. Note 3: The array capacity displayed by an operating system may be slightly different from the values listed. Note 4: NonStop supports LUSE and CVS.
Glossary AL Arbitrated loop. AL-PA Arbitrated loop physical address. array group A group of 4 or 8 physical hard disk drives (HDDs) installed in an XP disk array and assigned a common RAID level. RAID1 array groups consist of 4 (2D+2D) or 8 HDDs (4D+4D). RAID5 array groups include a parity disk but also consist of 4 (3D+1P) or 8 HDDs (7D+1P). All RAID6 array groups are made up of 8 HDDs (6D+2P).
host mode Each port can be configured for a particular host type. These modes are represented as two-digit hexadecimal numbers. For example, host mode 08 represents an HP-UX host. LDEV Logical device. An LDEV is created when a RAID group is carved into pieces according to the selected host emulation mode (that is, OPEN-3, OPEN-8, OPEN-L). The number of resulting LDEVs depends on the selected emulation mode. The term LDEV is often used synonymously with the term volume. LUN Logical unit number.
component separated by a colon. For example 00:00 and 01:00 are two uniquely identified volumes; one is identified as CU = 00 and LDEV = 00, and the other as CU = 01 and LDEV = 00; they are two unique separate virtual storage devices within the XP array. VSC Volume size customization. Synonymous with CVS. WWN World Wide Name. A unique identifier assigned to a Fibre Channel device.
