Understanding the Enterprise Virtual Array 1 This chapter introduces the Enterprise Virtual Array components and explains how the host servers are integrated.
Understanding the Enterprise Virtual Array About Virtualization Virtualization is used to simplify the creation, presentation, and administration of storage to multivendor host servers in a Storage Area Network (SAN). Virtualization changes the way the storage administrator interacts with storage—streamlining the work required to manage and implement the storage environment. This section describes how virtualization affects storage configuration.
Understanding the Enterprise Virtual Array About the Enterprise Virtual Array Storage system level virtualization is a concept in the storage industry that allows you to focus on higher-level concerns regarding your specific storage needs. With the Enterprise Virtual Array, you no longer need to manually present storage pools to the host servers. That is, you do not choose specific disks and sets of disks to create levels of redundancy.
Understanding the Enterprise Virtual Array Note: Unless otherwise specified, all references to either an HSV110 controller or HSV110 controller pair should be interpreted as the HSV110 or HSV100 controller. Storage Configuration All complex choices regarding physical disk usage, previously made manually, are now performed by the software. The end result is overall better performance and less intervention. The Command View EVA software automatically makes complex choices about physical disk usage.
Understanding the Enterprise Virtual Array Hosts and the Enterprise Virtual Array This section describes how the host servers fit in the overall Enterprise Virtual Array.
Understanding the Enterprise Virtual Array 2 5 1 3 4 SHR-2503AA Figure 1: SAN architecture 1 Fabric 2 Host servers 3 Enterprise Virtual Array storage systems 4 Browser for controlling the Command View EVA 5 Management Appliance—where the Command View resides Become familiar with the configuration requirements and the physical layout of your Enterprise Virtual Array. Refer to the documentation that came with your hardware.
Understanding the Enterprise Virtual Array SAN Considerations Ensure that your SAN components are all supported for use with the Enterprise Virtual Array. Design your SAN with an HP standard topology or by following the HP SAN design rules for creating custom topologies. Refer to the HP StorageWorks SAN Design Reference Guide for help with topology rules. The most up-to-date version of this guide can be found on the HP website at http://h18004.www1.hp.com/products/storageworks/san/documentation.html.
Understanding the Enterprise Virtual Array Virtual RAID Considerations Virtual RAID helps determine the level to which user data is protected—VraidX, where can be 0, 1, or 5. Redundancy is directly proportional to cost in terms of storage usage—the greater the level of data protection, the more storage space is required. There are three types of redundancy available with the Enterprise Virtual Array: 18 ■ Vraid0—No failure tolerance of data is provided.
Installing the Tru64 UNIX Kit 2 This chapter provides instructions for installing the Tru64 UNIX Kit for Enterprise Virtual Array. This kit lets you connect host servers to the virtual disks of the Enterprise Virtual Array.
Installing the Tru64 UNIX Kit Installing the Fibre Channel Adapter Supported Fibre Channel Adapters (FCAs) must be installed in the host server in order to communicate with the Enterprise Virtual Array. Refer to the platform-specific release notes for a list of supported FCAs. Because the Enterprise Virtual Array requires a multiple-path environment, a minimum of two FCA ports are required for each host.
Installing the Tru64 UNIX Kit Note: The SSSU CAPTURE CONFIGURATION command (see the entry on the CAPTURE CONFIGURATION command in the HP StorageWorks Storage System Scripting Utility Reference Guide) is the only way to capture, save, and recreate a storage system’s configuration. See the HP StorageWorks Storage System Scripting Utility Reference Guide for more information on using SSSU (included on the CD-ROM that came with this kit and referred to as “SSSU Guide”).
Installing the Tru64 UNIX Kit Installing the Storage System Scripting Utility The following SSSU install procedure assumes that you have loaded the web kit to a CD-ROM. 1. Insert the Tru64 UNIX Kit V3.0B for Enterprise Virtual Array CD-ROM. 2. Enter the following command to extract the file (for V5.x): # mount –r –t cdfs –o rrip /dev/disk/cdrom0c /mnt Note: Substitute your CD device for cdrom0c, if necessary. 3. Change directories on the CD-ROM by entering: # cd /mnt 4.
Installing the Tru64 UNIX Kit As your system starts up, startup information is logged in a file called messages where, among many other items, the version of the installed FCA drivers are recorded. 1. View the messages # cd/var/adm # view messages 2. Inspect the latest entry line for KGPSA (the FCA name). The following is an example: Jan 17 vmunix: KGPSA-CA : Driver Rev 1.32: F/W Rev 3.81A4(2.01A0) : wwn 1000-0000-c923-102 3. Ensure that you have version 1.29 or above for each of your FCAs.
Installing the Tru64 UNIX Kit 2. Search for “emx:” in the file. You should see the following lines: emx: # PCI_Option = <..., Device_Id - 0x1ae5, ...> # PCI_Option = <..., Device_Id - 0xf700, ...> 3. Copy and paste a copy of the line with Device_ID 0xf700, replacing the 0xf700 with 0xf800 and removing the opening '#' character. The results should look like the following: emx: PCI_Option = <..., Device_Id - 0xf800, ...> # PCI_Option = <..., Device_Id - 0x1ae5, ...> # PCI_Option = <...
Testing Connections to the Enterprise Virtual Array 3 This chapter describes how to test that the Tru64 UNIX host servers can connect to the Enterprise Virtual Array. This chapter also describes how to test that the Storage System Scripting Utility (SSSU) can connect to the Enterprise Virtual Array.
Testing Connections to the Enterprise Virtual Array Testing the Storage System Scripting Utility The Storage System Scripting Utility (SSSU) is installed from the Tru64 UNIX Kit V3.0B for Enterprise Virtual Array (see “Installing the Storage System Scripting Utility” on page 22). You should verify that SSSU runs from your host server.
Testing Connections to the Enterprise Virtual Array 3. Ensure that the host FCAs have been added by inspecting the Host folder in the Navigation tree of the Command View EVA. Creating and Presenting Virtual Disks This section describes how to create and present additional virtual disks to host servers and verify that the hosts can access them. 1. Create a virtual disk family on the Enterprise Virtual Array using the Command View EVA. 2.
Testing Connections to the Enterprise Virtual Array Scanning the Bus 1. You scan the bus for the virtual disk, and then display information about the Enterprise Virtual Array devices. Start the rescan of the FCA with hwmgr. # hwmgr-scan scsi All new virtual disks become visible to the host. 2. Assign device special files to the new virtual disks with dsfmgr. # dsfmgr -K Uppercase “K” reassigns device special files to all devices.
Testing Connections to the Enterprise Virtual Array View the hwmgr and dsfmgr man pages for more information on using these commands. If you are unable to access the virtual disk, check the following: ■ Verify all cabling to the switch, Enterprise Virtual Array, and host. ■ Verify all firmware levels (check the Enterprise Virtual Array QuickSpecs and associated release notes for details).
Testing Connections to the Enterprise Virtual Array To create the partitions on a virtual disk using the default partition sizes, enter the following: # disklabel -rw disk Where: disk is the character device name found in /dev/rdisk For example, to create partitions on block device, dsk8, enter: # disklabel -rw dsk8 To view a virtual disk partition, enter: # disklabel -r device Creating a File System on a Virtual Disk The newfs command is given here as an example for creating a UNIX File System (UFS).
Testing Connections to the Enterprise Virtual Array The virtual disk is now accessible to the file system just as a disk device would be. The file system cannot see the RAID functionality and number of physical devices attached to the HSV110 controller. This device appears as a single virtual disk or “disk” to the user as viewed by the file system. Tru64 UNIX Kit V3.

Additional Host Considerations 4 This chapter includes additional considerations for the host operating systems in an Enterprise Virtual Array. The following topics are covered: ■ Connecting Hosts to Switches, page 34 ■ Working with Clusters, page 35 ■ Expanding Volumes, page 35 Tru64 UNIX Kit V3.
Additional Host Considerations Connecting Hosts to Switches This section describes how to connect your host servers to the SAN switches in order to access the virtual disks. The documentation that came with the Enterprise Virtual Array hardware describes how to cable the controllers to the SAN switches. Note: Each host must attach to two redundant switches (fabrics) using standard fiber channel cables. These two switches in turn attach to the two HSV110 controllers on the Enterprise Virtual Array.
Additional Host Considerations Working with Clusters Clustering is the connecting of two or more computers together in such a way that they behave like a single computer. Clustering is used for parallel processing, load balancing, and fault tolerance. The supported clustering software for Tru64 UNIX is TruCluster. See the platform-specific release notes for the specific version of the supported clustering software. Be sure to install the Tru64 UNIX Kit on each server in the cluster.

glossary Glossary This glossary defines Enterprise Virtual Array terms used in this publication or related to this product and is not a comprehensive glossary of computer terms. Glossary active virtual disk A virtual disk (VD) is a simulated disk drive created by the controllers as storage for one or more hosts. An active virtual disk is accessible by one or more hosts for normal storage. An active virtual disk and its snapshot, if one exists, constitute a virtual disk family.
Glossary Command View EVA The graphical user interface through which a user controls and monitors a storage system. The Command View EVA software can be installed on more than one management appliance in a fabric. Each installation of the Command View EVA software is a management agent. communication logical unit number (LUN) See console LUN. console LUN A SCSI-3 virtual object that makes a controller pair accessible by the host before any virtual disks are created. Also called a communication LUN.
Glossary FC HBA Fibre Channel Host Bus Adapter. An interchangeable term for Fibre Channel adapter. See also FCA. FCA Fiber Channel Adapter. An adapter used to connect the host server to the fabric. Also called a Host Bus Adapter (HBA) or a Fibre Channel Host Bus Adapter (FC HBA). See also FC HBA. fiber The optical media used to implement Fibre Channel. fibre The international spelling that refers to the Fibre Channel standards for optical media.
Glossary Host Bus Adapter See FCA. host computer See host. host ports A connection point to one or more hosts through a Fibre Channel fabric. A host is a computer that runs user applications and that uses (or can potentially use) one or more of the virtual disks that are created and presented by the controller pair. host-side ports See host ports. initialization A process that prepares a storage system for use.
Glossary MBps Megabytes per second. A measure of bandwidth or data transfers occurring at a rate of 1,000,000 (106) bytes per second. Mega A notation denoting a multiplier of 1 million (1,000,000). metadata Information that a controller pair writes on the disk array. This information is used to control and monitor the array and is not readable by the host. mini-port driver The Windows driver type used for connecting to the Enterprise Virtual Array through the SAN fabric.
Glossary physical disk A disk drive mounted in a disk drive enclosure that communicates with a controller pair through the device-side Fibre Channel loops. A physical disk is hardware with embedded software, as opposed to a virtual disk, which is constructed by the controllers. Only the controllers can communicate directly with the physical disks. The physical disks, in aggregate, are called the array and constitute the storage pool from which the controllers create virtual disks.
Glossary SCSI ■ Small Computer System Interface. An American National Standards Institute (ANSI) interface which defines the physical and electrical parameters of a parallel I/O bus used to connect computers and a maximum of 16 bus elements. ■ The communication protocol used between a controller pair and the hosts. Specifically, the protocol is FC-AL or SCSI on a Fibre Channel. SCSI is the higher command-level protocol and Fibre Channel is the low-level transmission protocol.
Glossary StorageWorks The HP name used to describe the set of rack-mounted enclosures containing controllers, transceivers, I/O modules, EMUs, disk drives, cables, blowers, and power supplies used to design and configure a solution-specific storage system. switch An electromechanical device that initiates an action or completes a circuit. TB Terabyte. A term defining either: ■ A data transfer rate. ■ A measure of either storage or memory capacity of 1,099,5111,627,776 (240) bytes. See also TBps.
Glossary virtual disk family A virtual disk and its snapshot, if a snapshot exists, constitute a family. The original virtual disk is called the active disk. When you first create a virtual disk family, the only member is the active disk. See also active virtual disk, virtual disk copy, and virtual disk snapshot. virtual disk snapshot See snapshot.
