1 Installing and configuring NonStop for the XP disk array You and the HP service representative each play a role in installation. The 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 the HP service representative.
Check with your HP representative for other XP software available for your system. Fibre Channel interface The XP family of disk arrays supports these Fibre Channel elements: Connection speeds of 1 Gbps, 2 Gbps, and 4 Gbps 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...
SNMP configuration The XP family of disk arrays and the SVS 200 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 XP Remote Web Console or XP Command View Advanced Edition Software.
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 host group that is configured on a disk array port to match the host OS. Set the host mode using LUN Manager in XP Remote Web Console (shown) or XP Command View Advanced Edition Software.
Setting system option modes The HP service representative sets system option modes based on the operating system and software configuration of the host. In some situations, the system option modes shown in Table 1 on page 11 enable storage system behaviors that are more compatible with the requirements of a NonStop system than the default modes.
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.
Figure 3 Direct attach without a SAN example Table 2 Fabric topology settings Fabric Parameter Connection Parameter Provides FC-AL Not supported Point-to-Point N-port (SAN fabric port) NL-port (private arbitrated loop; direct connect without a FC-AL SAN) Point-to-Point Not supported Installing and configuring the host This section explains how to install and configure the host and Fibre Channel ServerNet Adapters (FCSAs) that connect the host to 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.
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. Record the LUNS and their ports, WWNs, nicknames, and LDEVs.

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. 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 XP Command View Advanced Edition Software (Alerts window) In XP Command View (Event History or Event Notification windows) (XP arrays only)

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]).

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.
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).

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.
