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 an HSV110 controller or an HSV110 controller pair should be interpreted as the HSV110 or HSV100 controller or controller pair. 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.
Understanding the Enterprise Virtual Array ■ IBM AIX ■ Linux ■ Novell NetWare Be sure you are running a supported version of each operating system in your SAN (see the platform-specific release notes for details). Figure 1 on page 18 shows an overall SAN architecture for the Enterprise Virtual Array. The control center for the Enterprise Virtual Array is Command View EVA, which resides on a management appliance. The management appliance is accessed from a browser anywhere on the network.

Understanding the Enterprise Virtual Array Become familiar with the configuration requirements and the physical layout of your Enterprise Virtual Array. Refer to the documentation that came with your hardware. Also, read the documentation and release notes for the additional hardware and software used throughout your SAN. SAN Considerations Ensure that your SAN components are all supported for use with the Enterprise Virtual Array.
Understanding the Enterprise Virtual Array Virtual RAID Considerations Virtual RAID helps determine the level to which user data is protected—VraidX, where X 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: 20 ■ Vraid0—No failure tolerance of data is provided.
Installing the HP-UX Kit 2 This chapter provides instructions for installing the HP-UX Kit for Enterprise Virtual Array.
Installing the HP-UX 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 FCAs are required for each host.
Installing the HP-UX Kit Installing Secure Path The Enterprise Virtual Array requires a multiple path-only environment. Secure Path for HP-UX provides this multiple path environment. You must have Secure Path installed on the host before any virtual disks can be recognized and configured. Installing the Host Kit The HP-UX Kit V3.0B for Enterprise Virtual Array installs the supported FCA driver and the Storage System Scripting Utility (SSSU).

Installing the HP-UX Kit As your system starts up, startup information is logged in a file called syslog.log (/var/adm/syslog/syslog.log) where, among many other items, versions of the installed FCA drivers are recorded. 1. To view the installed products, type the following: # swlist -l product A6795A 2. Inspect the latest entry line for the FCA driver. The following is an example: A6795AB.11.00.10PCI Tachyon TL/TS/XL2 Fibre Channel A6795A.FC-TACHYON-TLB.11.00.10PCI Tachyon TL/TS/XL2 Fibre Channel 3.
Testing Connections to the Enterprise Virtual Array 3 This chapter describes how to test that the HP-UX 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 HP-UX Kit V3.0B for Enterprise Virtual Array (see“Installing the Storage System Scripting Utility” on page 24). 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 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 Command View EVA. 2.
Testing Connections to the Enterprise Virtual Array Note: You could also restart the host machine to rescan for newly presented virtual disks, but restarting the host is not a requirement. Sample Output from a Rescan The following is a sample output from an ioscan command. # ioscan -fnCdisk Cla ss I H/W Path Dri ver S/W State H/W Typ e Description ====================================================================== dis k dis k 0 0/0/1/0.1.1 1 0/0/2/0.6.0 dis k 2 0/0/2/1.6.0 dis k 7 255/0.0.

If you are unable to access the virtual disk, check the following: ■ Verify all cabling to the switch, Enterprise Virtual Array, and host.
Testing Connections to the Enterprise Virtual Array Creating Volume Groups on a Virtual Disk Using vgcreate Create the partitions on a virtual disk by issuing a vgcreate command. The vgcreate command builds the virtual group block data needed in order to access the virtual disk for access by HP-UX. In addition, refer to the pvcreate, vgcreate, and lvcreate man pages for more information about creating disks and file systems.
Testing Connections to the Enterprise Virtual Array Creating a File System on a Virtual Disk The newfs command is used for creating a UNIX file system (HFS) or a Veritas File System (VxFS). Use the following procedure to create a file system on a Virtual disk. 1. Create a VxFS file system using the following command: newfs –F vxfs /dev/vg01/rlvol1 2.

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 35 ■ Working with Clusters, page 36 ■ Expanding Volumes, page 36 Connecting Hosts to Switches This section describes how to connect your host servers to the SAN switches in order to access the virtual disks.
Additional Host Considerations SHR-2457A Figure 2: Cabling hosts to switches For more information about connecting storage system components, refer to the HP StorageWorks SAN Design Reference Guide. 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 HP-UX is MC/Service Guard.
Additional Host Considerations Note: As with any large-scale operation, it is always best to first create a backup of your data. Offline Volume Expansion Workaround 1. Stop all applications using the virtual disk. 2. Copy all existing data to a safe location. 3. Unmount the virtual disk: # umount /data1 4. Disable the volume group: # vgchange –a n /dev/vg01 5. Create a new virtual disk by using Command View EVA. 6. Verify the creation of the virtual disk and note the device number.

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 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. console LUN ID The ID that can be assigned when a host operating system requires a unique ID. The console LUN ID is assigned by the user, usually when the storage system is initialized. See also console LUN.
Glossary fiber The optical media used to implement Fibre Channel. fibre The international spelling that refers to the Fibre Channel standards for optical media. Fibre Channel A data transfer architecture designed for mass storage devices and other peripheral devices that require very high bandwidth. Fibre Channel adapter See FCA. GB Gigabyte. A unit of measurement defining either: ■ A data transfer rate. ■ A storage or memory capacity of 1,073,741,824 (230) bytes. See also GBps.
Glossary host-side ports See host ports. initialization A process that prepares a storage system for use. Specifically, the system binds controllers together as an operational pair and establishes preliminary data structures on the disk array. Initialization also sets up the first disk group, called the default disk group. K Kilo. A scientific notation denoting a multiplier of one thousand (1,000). KB Kilobyte. A unit of measurement defining either storage or memory capacity.
Glossary mini-port driver The Windows driver type used for connecting to the Enterprise Virtual Array through the SAN fabric. mirrored caching A process in which half of each controller’s write cache mirrors the companion controller’s write cache. The total memory available for cached write data is reduced by half, but the level of protection is greater. mirroring The act of creating an exact copy or image of data. node port A device port that can operate on the arbitrated loop topology.
Glossary preferred path A preference for which controller of the controller pair manages the virtual disk. This preference is set by the user through the Command View EVA when creating the virtual disk. A host can change the preferred path of a virtual disk at any time. The primary purpose of preferring a path is load balancing.
Glossary SMART Self-Monitoring, Analysis, and Reporting Technology. An industry standard for running internal diagnostics on disk drives and making predictive failure analysis. If a physical disk drive reports an imminent failure, the controllers redistribute data to other drives. The SMART message is reported and should trigger the immediate corrective action to replace the drive. snapshot A temporary virtual disk (VD) that reflects the contents of another virtual disk at a particular point in time.
Glossary TBps Terabytes per second. A data transfer rate of 1,000,000,000,000 (1012) bytes per second. uninitialized system A state in which the storage system is not ready for use. See also initialization. Virtual Disk A simulated disk drive created by the controllers as storage for one or more hosts. The virtual disk characteristics, chosen by the storage administrator, provide a specific combination of capacity, availability, performance, and accessibility.
Glossary Vraid1 A virtualization technique that provides the highest level of data protection. All data blocks are mirrored or written twice on separate physical disks. For read requests, the block can be read from either disk, which can increase performance. Mirroring takes the most storage space because twice the storage capacity must be allocated for a given amount of data. Vraid5 A virtualization technique that uses parity striping to provide moderate data protection.
