1 Introduction This implementation guide provides the information you need to configure an HP 3PAR StoreServ Storage system with HP-UX 11i v2 (11.23) or v3 (11.31). General information is also provided on the basic steps required to allocate storage on the HP 3PAR StoreServ Storage that can then be accessed by the HP-UX host. The information contained in this implementation guide is the outcome of careful testing of the HP 3PAR StoreServ Storage with representative hardware and software configurations.

The tasks described in this manual assume that the administrator is familiar with HP-UX 11i v2 (11.23) or v3 (11.31) and the HP 3PAR OS. This guide provides basic information that is required to establish communication between the HP 3PAR StoreServ Storage and the HP-UX host and to allocate the required storage for a given configuration.

2 Configuring the HP 3PAR StoreServ Storage for Fibre Channel This chapter describes how to establish a connection between an HP 3PAR StoreServ Storage and HP-UX host using Fibre Channel and how to set up the fabric when running HP 3PAR OS 3.1.x or OS 2.3.x. For information on setting up the physical connection for a particular HP 3PAR StoreServ Storage, see the appropriate HP 3PAR installation manual.
PAGE 7
2. After all ports have been configured, verify that the ports are configured for a host in a direct connection by issuing the showport -par command on the HP 3PAR StoreServ Storage.

There are 2 HP-UX host personas: • Persona 7 for HPUX-legacy 11i v3 (11.31) for pre 3.1.3 releases and 11i v2 (11.23) Provides: VolSetAddr and Lun0SCC • Persona 13 for HP-UX 11i v3 (11.31) only in 3.1.

NOTE: The WWN used in the command above to create a host definition is the host N_Port Port World Wide Name (PWWN). An example of how to obtain the PWWN is as follows # fcmsutil /dev/fcd0 | grep "N_Port Port" N_Port Port World Wide Name = 0x5001438004257c22 2. To verify that the host has been created, issue the showhost command.

Required Employ fabric zoning, using the methods provided by the switch vendor, to create relationships between host server HBA ports and HP 3PAR StoreServ Storage ports before connecting to the fabrics. Fibre Channel switch vendors support the zoning of the fabric end-devices in different zoning configurations. There are advantages and disadvantages with each zoning configuration. Choose a zoning configuration based on your needs.

• The I/O queues are shared among the connected host server HBA ports on a first-come, first-served basis. • When all queues are in use and a host HBA port tries to initiate I/O, it receives a target queue full response from the HP 3PAR StoreServ Storage port. This condition can result in erratic I/O performance on each host server.

3 Connecting a Host Server with Fibre Channel This chapter describes the tasks necessary for connecting the host to Fibre Channel. Installing the HBA 1. 2. Install the HP-UX operating system from the HP-UX 11i v2 Mission Critical OE June 2008 Release, as well as the 11i v2 December 2010 Support Pack, or from the HP-UX 11i v3 Data Center OE March 2013 or later Release on Integrity/PA-RISC Servers.

The drivers are installed with the operating system. FibreChanl-00 must be installed for FibrChanl-01 to work. 2. Verify that the OnlineDiag or Support Tools Bundle software is installed and install the software if it is not present. The OnlineDiag bundle is present in the OS media. # swlist Online* # OnlineDiag 3. B.11.31.04.05 HPUX 11.31 Support Tools Bundle, September 2008 HP recommends that the server be at a certain firmware version to detect the fibre channel cards.

4 Allocating Storage for Access by the HP-UX Host Creating Storage on the HP 3PAR StoreServ Storage This section describes the general steps and commands that are required to create the virtual volumes (VVs) that can then be exported for discovery by the HP-UX host. For additional information, see the HP 3PAR Command Line Interface Administrator’s Manual. For a comprehensive description of HP 3PAR OS commands, see the HP 3PAR Command Line Interface Reference.

Creating Thinly-provisioned Virtual Volumes To create thinly-provisioned virtual volumes (TPVVs), see the following documents: • HP 3PAR StoreServ Storage Concepts Guide • HP 3PAR Command Line Interface Administrator’s Manual • HP 3PAR Command Line Interface Reference These documents are available on the HP Support Center website: HP Support Center Exporting LUNs to the Host This section explains how to export LUNs to the host server as VVs, referred to as virtual LUNs (VLUNs).

PVLinks, a component of Logical Volume Manager (LVM), can be used with storage server VVs that are exported on multiple paths to the host server to provide path failure management. PVLinks is an alternate pathing scheme where a primary and one or more alternate paths are defined for a device.

5 Removing HP 3PAR Devices on the Host Server To remove a VV from the HP-UX 11i v3 or 11i v2 host, complete the following steps: 1. See the appropriate HP-UX document for removing a specific volume type (for example, VxVM, LVM). 2. Remove the VLUN from the HP 3PAR StoreServ Storage by issuing removevlun .

HP 3PAR StoreServ Storage Setup Requirements Booting from the HP 3PAR StoreServ Storage is supported in fabric and direct connect modes. Make sure you have allocated enough space when creating your virtual volumes to be able to install your HP-UX OS.

7 Using Symantec Storage Foundation As of HP 3PAR OS 3.1.2, the virtual volume (VV) WWN increased from 8 bytes to 16 bytes. The increase in WWN length may cause the Symantec ASL to incorrectly identify the array volume identification (AVID) number, subsequently resulting in use of a different naming convention for DMP disk devices. NOTE: This issue does not occur with Storage Foundation 6.1, which is compatible with both 8-byte and 16-byte WWNs.
