Page 8: Overview
HP XP7 Mainframe Host Attachment and Operations Guide. Audience This document is intended for system administrators, HP representatives, and authorized service providers who are involved in installing, configuring, and operating the HP XP7 storage systems. Features and requirements The disk array provides following features:...
Page 9: Fibre Channel Interface
HP XP7 Array Manager Software Check with your HP representative for other XP7 software available for your system. NOTE: Linux, NonStop, and Novell NetWare: Make sure you have superuser (root) access. OpenVMS firmware version: Alpha System firmware version 5.6 or later for Fibre Channel support.
Page 10: Device Emulation Types
LDEVs without losing data. Using any other emulation might cause data loss in the external storage LUNs. For new deployments, use OPEN-V, because some features (such as features available with HP XP7 Snapshot Software or HP XP7 Continuous Access Journal Software) are only supported with OPEN-V.
Page 11: Snmp Configuration
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 the XP7 Remote Web Console or XP7 Command View Advanced Edition Suite Software. For specific procedures, see the applicable user guide.
Page 12: Hp-Ux
2 HP-UX 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.
Page 13: Defining The Paths
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 the XP7 Remote Web Console (shown) or XP7 Command View Advanced Edition Software. If these are not available, the HP service representative can set the host mode using the SVP.
Page 14 The correct host mode must be set for all new installations (newly connected ports) to HP-UX hosts. Do not select a mode other than 08 for HP-UX. Changing a host mode after the host has been connected is disruptive and requires the server to be rebooted.
Page 15: Configuring The Fibre Channel Ports
Configure the disk array Fibre Channel ports by using XP7 Command View Advanced Edition Software or the XP7 Remote Web Console. Select the settings for each port based on your SAN topology. Use switch zoning if you connect different types of hosts to the array through the same switch.
Page 16: Fabric Zoning And Lun Security For Multiple Operating Systems
SAN) Connecting the disk array The HP service representative performs the following steps to connect the disk array to the host: Verifying operational status of the disk array channel adapters, LDEVs, and paths. Connecting the Fibre Channel cables between the disk array and the fabric switch or host.
Page 17: Verifying Fca Installation
DEVICE... In the example: HP OPEN-9 device: SCSI bus number = 14/12, bus instance = 6, SCSI target ID = 0, LUN = 0. HP OPEN-9*2 device: SCSI bus number = 14/12, bus instance = 6, SCSI target ID = 0, LUN = 1.
Page 18: Configuring Disk Array Devices
“Setting and verifying the auto-mount parameters” (page 24) The HP-UX system uses the Logical Volume Manager (LVM) to manage the OPEN-x devices on the disk array. The instructions in this section do not explicitly cover all LVM configuration issues. For further information on LVM configuration, see the HP-UX user documentation.
Page 19: Verifying The Device Files And Drivers
To allow more volume groups to be created, use SAM to modify the HP-UX system kernel configuration. See “Reference information for the HP System Administrator Manager SAM” (page 149) for details. The newer releases of HP-UX have deprecated the SAM tool and replaced it with the System Management Homepage (SMH) tool. To create volume groups: Use the vgdisplay command to display the existing volume groups.
Page 20: Creating Logical Volumes
Use these commands for logical volume configuration: lvremove Deletes a logical volume. Any file system attached to the logical volume must be unmounted before executing the lvremove command. Example lvremove /dev/vgnn/lvolx lvextend Increases the size of an existing logical volume. HP-UX...
Page 21 L command to create a logical volume. Specify the volume size (in megabytes) and the volume group for the new logical volume. HP-UX assigns the logical volume numbers automatically (lvol1, lvol2, lvol3). Use the following capacity values for the size parameter:...
Page 22: Creating The File Systems
Create the file system for each new logical volume on the disk array. The default file system types are: HP-UX OS version 1 1.i = vxfs To create file systems: Use the newfs command to create the file system using the logical volume as the argument.
Page 23: Creating The Mount Directories
Verify the current I/O timeout value using the pvdisplay command: Example # pvdisplay /dev/dsk/c0t6d0 - - - Physical volumes - - - PV Name /dev/dsk/c0t6d0 VG Name /dev/vg06 PV Status available Allocatable VGDA Cur LV PE Size (Mbytes) Total PE Free PE Allocated PE 586 [OPEN-9]...

Click Manage. Navigate to Diagnostics then click Device Manager. Navigate to the Disk drives section and expand the section. Right-click each device labeled HP OPEN-V Multi-Path Disk Device then click Properties. Record the device information using the worksheet in “Worksheet” (page 111).
Page 33 Click OK to update the system configuration and start the Write Signature wizard. For each new disk, click OK to write a signature, or click No to prevent writing a signature. When you have performed this process for all new disks, the Disk Management main window opens and displays the added disks.
Page 34: Creating And Formatting Disk Partitions
Creating and formatting disk partitions Dynamic Disk is supported with no restrictions for a disk array connected to a Windows 2008/2012 system. For more information, see Microsoft's online help. 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.) In the Disk Management main window, select the unallocated area for the SCSI disk you want to partition.

Page 41: Defining The Paths
Use XP7 Command View Advanced Edition Software or the XP7 Remote Web Console (shown) to define paths between hosts and volumes (LUNs) in the disk array. This process is also called “LUN mapping.” In the XP7 Remote Web Console, LUN mapping includes:...
Page 42: Setting The Host 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 the XP7 Remote Web Console (shown) or XP7 Command View Advanced Edition Software. For procedures, see the applicable user guide available at http://www.hp.com/support/manuals.
Page 43: Setting The Uuid
Use this host mode to enable the option that sets the UUID Setting the UUID HP recommends that OpenVMS customers use host mode option 33 to enable the UUID feature. This increases the capabilities for OpenVMS hosts that access the disk array, by: Allowing the presentation of CU:LDEVs before 7F:FF to the OpenVMS hosts.
Page 44 If host mode option 33 is not set, then the default behavior is to present the volumes to the OpenVMS host by calculating the decimal value of the hexadecimal CU:LDEV value. That calculated value will be the value of the DGA device number. CAUTION: The UUID (or by default the decimal value of the CU:LDEV value) must be unique across the SAN for the OpenVMS host and/or OpenVMS cluster.
Page 45: Setting The System Option Modes
Configure the disk array Fibre Channel ports by using XP7 Command View Advanced Edition Software or the XP7 Remote Web Console (shown). Select the settings for each port based on your SAN topology. Use switch zoning if you connect different types of hosts to the array through the same switch.

Host FCA configuration (WWN information, driver instance, target and LUN assignment, and /var/adm/messages) If you are using the Oracle SAN driver and XP7 LUNs were not present when the configuration was done, you may need to reset each FCA if no LUNs are visible. The following example shows the commands to detect the FC-fabric attached FCAs (c3, c5) and resetting them.
Page 77: Labeling And Partitioning The Devices
CAUTION: The repair, analyze, defect, and verify commands/menus are not applicable to the XP7 arrays. When selecting disk devices, be careful to select the correct disk as using the partition/label commands on disks that have data can cause data loss.
