1 Installing and configuring Windows 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. Features and requirements Ask your HP service representative about the latest supported hardware and software.
Device emulation types The XP family of disk arrays supports these device emulation types: • OPEN-3/8/9/E/L/V devices: OPEN-x logical units represent disk devices. Except for OPEN-V, these devices are based on fixed sizes. OPEN-V is a user-defined size. Supported emulations include OPEN-3, OPEN-8, OPEN-9, OPEN-E, OPEN-L, and OPEN-V devices.
Figure 1 SNMP configuration XP RAID Manager command devices HP StorageWorks XP RAID Manager manages HP StorageWorks XP Business Copy Software or HP StorageWorks XP Continuous Access Software operations from a host server. To use XP RAID Manager you must designate at least one LDEV as a command device. This can be done with XP Command View (XP arrays only), XP Remote Web Console , or Command View XP Advanced Edition Software.
After completing these tasks, use XP Command View (XP disk arrays only), XP Remote Web Console, Command View XP Advanced Edition Software, or LUN Configuration and Security Manager to complete the remaining installation tasks. If you do not have these programs, your HP service representative can perform these tasks for you. 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.
CAUTION: The correct host mode must be set for all new installations (newly connected ports) to Windows 2000/2003 hosts. Do not select a mode other than 2C or 0C for Windows 2000/2003. 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.
Setting the System Option Mode The HP service representative sets the System Option Mode(s) based on the operating system and software configuration of the host. Configuring the Fibre Channel ports Configure the disk array Fibre Channel ports using XP Remote Web Console (shown), XP Command View (XP arrays only), or Command View XP Advanced Edition Software. Select the settings for each port based on your storage area network topology.
Figure 2 Point-to-point fabric topology example Table 5 Fabric topology settings Fabric parameter Connection parameter Provides OFF FC-AL NL-port (private arbitrated loop) ON FC-AL FL-port (public loop) for loop connection to a switch ON POINT-TO-POINT N-port (fabric port) for connection to a switch OFF POINT-TO-POINT Not supported Installing and configuring the host This section explains how to install and configure the host and host bus adapters (HBAs) that connect the host to the disk arra
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 with the following restrictions: • 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.
Figure 3 Multi-cluster environment Connecting 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 XP Remote Web Console (shown), XP Command View (XP arrays only), or Command View XP Advanced Edition Software to define paths (LUNs) between hosts and volumes in the disk array. This process is also called “LUN mapping.
In Command View XP Advanced Edition Software, LUN mapping includes: • Configuring ports • Creating storage groups • Mapping volumes and WWN/host access permissions to the storage groups For details see the HP StorageWorks LUN Configuration and Security Manager User's Guide or Command View XP Advanced Edition Software Device Manager Web Client User's Guide. Note the LUNs and their ports, WWNs, nicknames, and LDEVs for later use in verifying host and device configuration.
Configure disk devices Disk arrays are configured using the following procedures: • Writing signatures • Creating and formatting disk partitions • Verifying file system operations Writing signatures 1. Right-click My Computer and then click Manage. 2. Click Disk Management. A message notifies you that disks have been added. 3. Click OK to update the system configuration and start the Write Signature wizard. 4.
2. Click the Action menu, and then click Create Partition to launch the New Partition Wizard. Follow the Partition Wizard to create and format partitions and assign drive letters. Format partitions with the following settings and format options. File System: NTFS (enables Windows to write to the disk). Allocation unit size: Default. Do not change this entry. Volume label: Enter a volume label, or leave this field blank for no label.
2 Troubleshooting This section includes resolutions for various error conditions. If you are unable to resolve an error condition, contact your HP support representative for assistance. See “Calling the HP support center” on page 24. Error conditions Depending on your system configuration, you may be able to view error messages (R-SIMS) as follows: • In XP Remote Web Console (Status tab) • In Command View XP Advanced Edition Software (“Alerts” panel).
Table 7 Error conditions Error condition Recommended action The logical devices are not recognized by the host. Verify the following: • The READY indicator lights on the disk array are ON. • Fiber cables are correctly installed and firmly connected. • The target IDs are properly configured. The LUNs for each TID must start at 0 and continue sequentially without skipping any numbers. • The TIDs/WWNs on each bus are unique. Do not install two devices with the same ID on the same bus.

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.
Emulation specifications Table 10 Emulation specifications Emulation(Note 1) Category (Note 2) Blocks (512 bytes ) Sector Size (bytes) OPEN-3 SCSI disk 4806720 512 3338 OPEN-8 SCSI disk 14351040 512 OPEN-9 SCSI disk 14423040 OPEN-E SCSI disk OPEN-L OPEN-V # of Cylinders Heads Sectors per track Capacity MB*(Note 3) 15 96 2347 9966 15 96 7007 512 10016 15 96 7042 28452960 512 19759 15 96 13893 SCSI disk 71192160 512 49439 15 96 34761 SCSI disk max=125827200 51
Note 1: The availability of an emulation depends on the disk array. Note 2: The devices are defined to the host as SCSI disk devices, even though the interface is Fibre Channel. Note 3: The device capacity can sometimes be changed by the BIOS or host adapter board. This may make actual capacity different from that listed in the table.
Example For a CVS LUSE volume with capacity = 37 MB and n = 4: # of cylinders = 37 × 1024/720 × 4 = 52.62 × 4 = 53 × 4 = 212 OPEN-V: The number of cylinders for a CVS LUSE volume =# of cylinders = (capacity (MB) specified by user) × 16/15 × n Example For an OPEN-V CVS LUSE volume with capacity = 49 MB and n = 4: # of cylinders = 49 × 16/15 × 4 = 52.26 × 4 = 53 × 4 = 212 Note 6: The capacity of an OPEN-3/8/9/E CVS volume is specified in MB, not number of cylinders.
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.
