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.
HP HP HP HP HP HP HP StorageWorks StorageWorks StorageWorks StorageWorks StorageWorks StorageWorks StorageWorks Data Exchange XP Resource Manager XP RAID Manager XP Cache LUN XP Auto Path XP Cluster Extension XP Performance Advisor XP Fibre Channel interface The MPE/iX host can use the A6795A 2 Gbps Fibre Channel HBA to connect to the disk array. The disk array port should not use auto negotiate to detect the speed of the host Fibre Channel adapter. Configure it "hard" to either 1 or 2 Gbps.
SNMP configuration The XP family of disk arrays supports standard Simple Network Management Protocol (SNMP) for remotely managing the disk array. 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 Remote Web Console XP, Command View XP, 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 for the disk array ports • Setting the System Option Modes • Configuring the Fibre Channel ports 2. Install the host hardware • Installing the host system • Installing and configuring the HBAs • Fabric zoning and LUN security • Multiple operating systems in a shared switch fabric 3.
Install and configure the disk array The HP service representative performs these tasks: • Assembling hardware and installing software • Loading the microcode updates • Installing and formatting devices After these tasks are finished, you will use Remote Web Console, Command View, Command View XP Advanced Edition, or LUN Configuration and Security Manager to complete the remaining tasks listed below. If you do not have these programs, your HP service representative can perform these tasks for you.
For the XP1024/XP128 arrays, the host mode can also be set at the port information window in Command View XP AE.
Setting the System Option Modes 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 by using Remote Web Console (shown), Command View, or Command View XP AE. 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.
Fabric and connection parameter settings For HP e3000 systems, set the port topology to FABRIC ON and the connection parameter to FC-AL. This provides an NL-port on the disk array (public arbitrated loop) and is the recommended supported topology. Install the host hardware This section explains how to install and configure the host and host bus adapters (HBAs) that connect the host to the disk array.
When you are installing A6795A Fibre Channel HBAs on A-Class and N-Class systems, be sure to record the I/O slot paths where you install the cards. You will need the I/O paths of these HBAs later during the I/O configuration procedure. For SCSI HBA installations, recording the I/O paths is not required. You can determine those I/O later using the MAPPER/MAPPER2 facility. Fabric zoning and LUN security If you plan to use clustering, install and configure the clustering software on the servers.
Multiple operating systems in a shared switch fabric By using appropriate zoning and LUN security, you can connect multiple clusters with multiple operating systems to the same switch and fabric.
Defining the paths Use Remote Web Console (shown), Command View, or Command View XP AE to define paths (LUNs) between hosts and volumes in the disk array. This process is also called “LUN mapping.
Determining storage capacity per path An important difference between MPE/iX and other operating systems (such as HP-UX) is the determination of disk capacity on a path. MPE/iX is very sensitive to spindle count (LUNs) per path. If this count exceeds 16 per bus or path, performance problems may result. To determine the available storage capacity in a path, subtract required system and application I/O space from the total disk capacity and divide the result by the spindle count (number of LUNs) in the path.
For a pre-existing system to which new XP disk array devices are being added, you will already have an operable system on an existing Ldev 1 boot disk that you can start up. For a newly installed system, boot the system from the primary boot path just used to install the system, and start the OS using the appropriate factory configuration group, as described in the System Software Maintenance Manual.
Further detailed information about determining I/O paths for Fibre Channel disk arrays can be found in the HP e3000 Fibre Channel Mass Storage Adapters Service and User Manual, and in the MPE/iX Release 7.5 Communicator article “Fibre Channel Device and Adapter Support on HP e3000 Systems.” 1. With the system booted up, use IOCONFIG to configure the I/O paths for the Fibre Channel HBAs (located at paths 0/4/0/0 and 0/6/0/0 in this example): Example CSYLE18:ioconfig IOCONFIG A.00.00 (catalog A.00.

Use the MAPPER (or MAPPER2 for A-Class and N-Class) I/O mapping utility program in the Offline Diagnostic Environment (ODE) to display the I/O paths for the SCSI HBAs and the disk array devices (targets and LUNs). Then use either SYSGEN or MPE/iX’s IOCONFIG utility command and the I/O paths reported by MAPPER to perform the MPE/iX I/O configuration of SCSI HBAs and disk Ldevs. To configure disk array devices attached by SCSI-FC Fabric Router: 1. Boot the system to the ISL> prompt on the primary boot path.

Create volume sets and volumes After I/O configuration has been completed, create volume sets and member volumes on the disk array devices using the VOLUTIL utility in the same way that you would do these tasks for any other MPE/iX disk. Refer to the Volume Management manual (32650-90045) and to the VOLUTIL section of the MPE/iX System Utilities Reference Manual (32650-90908) for detailed information on volume creation and management.

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 for more information. Error conditions Depending on your system configuration, you may be able to view error messages (R-SIMS) as follows: • In Remote Web Console (Status tab) • In Command View Advanced Edition (“Alerts” panel).
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. Verify that fiber cables are correctly installed and firmly connected. Verify that the target IDs are properly configured. The LUNs for each TID must start at 0 and continue sequentially without skipping any numbers.Verify that the TIDs/WWNs on each bus are unique. Do not install two devices with the same ID on the same bus.
Calling the HP support center If you are unable to resolve an error condition, contact the HP support center for assistance.

A Disk array supported emulations This appendix provides information about supported emulations and device type specifications. Some parameters may not be relevant to your array. Consult your HP representative for information about supported configurations for your system. Supported emulations MPE/iX systems support ONLY the OPEN-x emulations. LUSE and CVS are not supported.

Disk array supported emulations
B Booting from the array In order to use a native Fibre Channel-connected disk array as MPE/iX Ldev 1 (the boot disk) to load, boot, and run the OS software, you must know the primary I/O boot path leading to the desired LUN in the XP disk array. The primary boot path must be set into PDC memory so that the processor will be able to perform I/O to the disk device during system boot operations.
If the system does not already have an MPE/iX Release 7.5 OS installed and the disk array you want to use for MPE/iX Ldev 1 is SAN-connected (through a Fibre Channel switch) to the host HP e3000 system, then use the following procedure. a. You CANNOT use the MAPPER2 facility to determine the I/O paths for the disk array. MAPPER2 will not be able to recognize and report the LUNs of the disk array on the Fibre Channel switch. b.
Follow this procedure if you have an existing boot disk: 1. Perform a normal boot and start of the system from the existing boot disk.

Set the system’s primary boot path to the BOOT MENU PATH you noted in step 4 above.
No existing MPE/iX boot disk available and the disk array is direct Fibre Channel connected If you have no boot disk available and the disk array is direct Fibre Channel connected, you can use the MAPPER2 utility while the system is booted from the SLT tape on the alternate boot path. MAPPER2 will locate and display the boot menu I/O paths for the direct Fibre Channel attached disk arrays.

No existing MPE/iX boot disk available and the disk array is Fibre Channel switch connected If you have no boot disk and the array is connected to a Fibre Channel switch, the MAPPER2 utility CANNOT be used to determine the I/O paths for the disk array devices.
Click on the Name Server button to access the Name Server display, and the switch will present a display name server table similar to the one that follows. You should already know the port number of the plug-in port on the Fibre Channel switch where you have connected the disk array. If necessary, trace the Fibre Channel cable from the disk array to the switch and determine the port to which the array is connected. In the figure above, the disk array is connected to port 5 of the switch.
The Port ID column of the display has the information needed to form the FC N-Port part of the I/O path. The Port ID is a 6-character hexadecimal digit (3 bytes) that decomposes into the three portions (Domain.Area.Port) of the FC N-Port part of the I/O path. Since PDC boot paths are set as decimal numbers, these three portions of FC N-Port value have to be converted from hex to decimal before you can use them to set the primary boot path.
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.
DKU (disk cabinet unit) The array cabinets that house the disk array physical disks. emulation modes The logical devices (LDEVs) associated with each RAID group are assigned an emulation mode that makes them operate like OPEN system disk drives. The emulation mode determines the size of an LDEV: OPEN-3: 2.46 GB OPEN-8: 7.38 GB OPEN-9: 7.42 GB OPEN-E: 13.
LDEVs. Essentially, LUSE makes it possible for applications to access a single large pool of storage. The LUSE feature is available when the HP StorageWorks LUN Configuration Manager product is installed. OFC Open Fibre Control. OPEN-x A general term describing any one of the supported OPEN emulation modes (for example, OPEN-L). OS Operating system. PA Physical address. path “Path” and “LUN” are synonymous. Paths are created by associating a port, a target, and a LUN ID with one or more LDEVs.
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.
