HP XP storage systems use the following values to calculate logical storage capacity values (logical devices): • 1 KB (kilobyte) = 1,024 bytes • 1 MB (megabyte) = 1,024 2 bytes • 1 GB (gigabyte) = 1,024 3 bytes • 1 TB (terabyte) = 1,024 4 bytes •... -

Page 11: Installing And Configuring Nonstop For The Xp Disk Array
1 Installing and configuring NonStop 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. -
Page 12: Device Emulation Types
• Short-wave non-OFC (open fiber control) optical interface • Multimode optical cables with LC connectors • Direct connect (PriNL) or fabric switch connect (N-port or DFA) • Fibre Channel switches 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. -

Page 14: Setting The System Option Modes
CAUTION: The correct host mode must be set for all new installations (newly connected ports) to NonStop hosts. Do not select a mode other than 0C or 2C for NonStop. Changing a host mode after the host has been connected is disruptive and requires the server to be rebooted. -
Page 15: Fibre Address
Fibre address In fabric environments, the port addresses are assigned automatically. In arbitrated loop environments, set the port addresses by selecting a unique arbitrated loop physical address (AL-PA) or loop ID for each port. For specific values, refer to the HP StorageWorks XP LUN Manager User's Guide applicable to your array. -

Page 17: Connecting The Disk Array
• Do not connect other operating systems to the same XP ports or even use a port that shares a processor with the same port as NonStop systems. • Use SAN switches dedicated to NonStop connections, or solutions that have been qualified by HP. -
Page 18: Verifying Disk Array Device Recognition
In XP Command View Advanced Edition, LUN mapping includes: • Configuring ports • Creating storage groups • Mapping volumes and WWN/host access permissions to the storage groups For details, see HP StorageWorks XP LUN Manager User's Guide or XP Command View Advanced Edition Device Manager Web Client User's Guide. -

Page 23: B Disk Array Supported Emulations
B Disk array supported emulations This appendix provides information about disk array 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. Supported emulations HP recommends using OPEN-V as the emulation for better performance and features that may not be supported with the legacy emulations (OPEN-[389LE]). - Page 24 Note 1: The availability of an emulation depends on the disk array. Note 2: OPEN-V is a variable device type. The maximum configurable LDEV size depends on the RAID level and size of physical disks configured in the array. The minimum size is 46 MB. Note 3: The array capacity displayed by an operating system may be slightly different from the values listed.

Page 25: Glossary
Glossary 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). - Page 26 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-E). The number of resulting LDEVs depends on the selected emulation mode. The term LDEV is often used synonymously with the term volume. Logical unit number.
