Preface
1 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. Features and requirements Ask your HP service representative about the latest supported hardware and software. The disk array has the following features: • Storage capacity.
Fibre Channel interface The XP family of disk arrays and the SVS200 support these Fibre Channel elements: • • • • Connection speeds of 1 Gbps, 2 Gbps, and 4 Gbps (XP12000/XP10000 only) 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 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.
SNMP configuration The XP family of disk arrays and the SVS200 support standard Simple Network Management Protocol (SNMP) for remotely managing arrays. The SNMP agent on the service processor (SVP) performs error-reporting operations requested by the SNMP manager. SNMP properties are usually set from the SVP but they can also be set remotely using Command View (XP arrays only), Remote Web Console, or Command View XP Advanced Edition. Refer to the applicable user’s guide for procedures.
Installation procedures Perform these actions to install and configure the disk array: 1. Install and configure the disk array • Setting the host mode and host group mode • Setting the System Option Mode • Configuring the Fibre Channel ports 2. Install and configure the host • Loading the OS and software • Installing and configuring the HBAs • Fabric zoning and LUN security 3. Connect the disk array • Defining the paths • Verifying the host recognizes array devices 4.
Setting the host mode and host group mode for the disk array ports After the disk array is installed, you must set the host mode for each disk array port to match the host OS. Set the host mode using LUN Manager in Remote Web Console (shown), Command View (XP arrays only), or Command View XP Advanced Edition. If these are not available, the HP service representative can set the host mode using the SVP.
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. The following host group modes are available for Windows 2000/2003: Host Group Mode 2 (Windows 2003 only) 6 Function Default VERITAS DBE+RAC Database Edition/Advanced Cluster for Real Application Clusters or VERITAS® Cluster Server 4.0 with I/O fencing is used.
Configuring the Fibre Channel ports Configure the disk array Fibre Channel ports by using Remote Web Console (shown), Command View (XP arrays only), or Command View XP Advanced Edition. 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.
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 Reference Guide on the www.hp.com website.
Cross-referencing HBAs The following table identifies both the HP part number and the HBA manufacturer’s number for common HBAs.
Fabric zoning and LUN security By using appropriate zoning and LUN security, you can connect various servers with various operating systems to the same switch and fabric: • 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.
Connect the disk array The HP representative connects the cables between the array and the host or between the array and the SAN. Defining the paths Use Remote Web Console (shown), Command View (XP arrays only), or Command View XP Advanced Edition to define paths (LUNs) between hosts and volumes in the disk array. This process is also called “LUN mapping.
Verifying the host recognizes array devices 1. Log into the host as an administrator. 2. Right-click the My Computer desktop icon, and click Manage. 3. Click Device Manager. 4. Click SCSI and RAID Controllers. 5. Click the host bus adapter to open it, and verify all devices are displayed. 6. Click each device, click Properties, and then click Settings. 7. Record the device information on the worksheet in Appendix A.
Creating and formatting disk partitions Dynamic Disk is supported with no restrictions for a disk array connected to a Windows 2000/ 2003 system. Refer to Microsoft’s online help for details. CAUTION: Do not partition or create a file system on a device that will be used as a raw device (for example, some database applications use raw devices.) 1. In the Disk Management main window, select the unallocated area for the SCSI disk you want to partition. 2.

2 Troubleshooting This section includes resolutions for various error conditions you may encounter. If you are unable to resolve an error condition, ask your HP support representative for assistance. See Calling the HP support center.
Error conditions Depending on your system configuration, you may be able to view error messages (R-SIMS) as follows: • In Remote Web Console XP (Status tab) • In Command View XP Advanced Edition (“Alerts” panel). • In Command View XP (Event History or Event Notification panels) (XP arrays only) Error condition Recommended action The logical devices are not recognized by the host. Verify that the READY indicator lights on the disk array are ON.
Calling the HP support center If you are unable to resolve an error condition, contact the HP support center for assistance. Contact information Telephone numbers for worldwide technical support are listed on the HP support web site: http://www.hp.com/support/.

B Disk array supported emulations This appendix provides information about 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.

Disk array supported emulations
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). BC HP StorageWorks Business Copy XP.
HBA Host bus adapter. 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.
TB Terabyte. TID Target ID. Volume On the XP array, a volume is a uniquely identified virtual storage device composed of a control unit (CU) component and a logical device (LDEV) 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.
