Page 10: Overview
1 Overview What's in this guide This guide includes information on installing and configuring P9000 disk arrays. The following operating systems are covered: HP-UX Windows Novell Netware NonStop OpenVMS VMware Linux Solaris IBM AIX For additional information on connecting disk arrays to a host system and configuring for a mainframe, see the HP StorageWorks P9000 Mainframe Host Attachment and Operations Guide.
Page 11: Fibre Channel Interface
For all operating systems, before installing the disk array, ensure the environment conforms to the following requirements: Fibre Channel Adapters (FCAs): Install FCAs, all utilities, and drivers. For installation details, see the adapter documentation. HP StorageWorks XP Remote Web Console or HP StorageWorks P9000 or XP Command View Advanced Edition Software for configuring disk array ports and paths.
Page 12: Device Emulation Types
Device emulation types The XP family of disk arrays and the SVS 200 support these device emulation types: OPEN-x 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 based on a CVS device. Supported emulations include OPEN-3, OPEN-8, OPEN-9, OPEN-E, OPEN-L, and OPEN-V devices.
Page 13: Snmp Configuration
Your HP representative might need to set specific disk array system modes for these products. Check with your HP representative for the current versions supported. For I/O path failover, different products are available from Oracle, Veritas, and HP. Oracle supplies software called STMS for Solaris 8/9 and Storage Multipathing for Solaris 10. Veritas offers VxVM, which includes DMP.
Page 14: Hp-Ux

You are responsible for configuring the host server for the new devices with assistance from the HP service representative. Installation roadmap Perform these actions to install and configure the disk array: “Installing and configuring the disk array”...
Page 15: Defining The Paths
Defining the paths Use P9000 or XP Command View Advanced Edition Software or XP 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 XP Remote Web Console, LUN mapping includes: Configuring ports Enabling LUN security on the ports Creating host groups...
Page 16: Setting The System Option Modes
CAUTION: 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. When a new host group is added, additional host group modes (options) can be configured.
Page 17: Configuring The Fibre Channel Ports
Configuring the Fibre Channel ports Configure the disk array Fibre Channel ports by using P9000 or XP Command View Advanced Edition Software or XP 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.
Page 18: Fabric Zoning And Lun Security For Multiple Operating Systems
Figure 2 Multi-cluster environment (HP-UX) Within the SAN, the clusters can be homogeneous (all the same operating system) or heterogeneous (mixed operating systems). How you configure LUN security and fabric zoning depends on the operating system mix and the SAN configuration. Fabric zoning and LUN security for multiple operating systems You can connect multiple clusters with multiple operating systems to the same switch and fabric using appropriate zoning and LUN security as follows:...

Page 21: Verifying The Device Files And Drivers
Verifying the device files and drivers The device files for new devices are usually created automatically during HP-UX startup. Each device must have a block-type device file in the /dev/dsk directory and a character-type device file in the /dev/rdsk directory. However, some HP-compatible systems do not create the device files automatically.
Page 22 repeat the procedures in “Verifying device recognition” (page 19) to verify new device recognition and the device files and driver. Example # insf -e insf: Installing special files for mux2 instance 0 address 8/0/0 Failure of the insf e command indicates a SAN problem. If the device files for the new disk array devices cannot be created automatically, you must create the device files manually using the mknodcommand as follows: Retrieve the device information you recorded earlier.
Page 23: Creating The Physical Volumes
Create the device files for all disk array devices (SCSI disk and multiplatform devices) using the mknodcommand. Create the block-type device files in the /dev/dsk directory and the character-type device files in the /dev/rdsk directory. Example # cd /dev/dsk Go to /dev/dsk directory. # mknod /dev/dsk/c2t6d0 b 31 0x026000 Create block-type file.
Page 24 The physical volumes that make up one volume group can be located either in the same disk array or in other disk arrays. 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 for details.
Page 25: Creating Logical Volumes
Use vgdisplay v to verify that the volume group was created correctly. The v option displays the detailed volume group information. Example # vgdisplay v /dev/vg06 - - - Volume groups - - - VG Name /dev/vg06 VG Write Access read/write VG Status available...
Page 26 To create logical volumes: Use the lvcreate 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: OPEN-K = 1740 OPEN-3 = 2344...
Page 27: Creating The File Systems
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 10.20 = hfs or vxfs, depending on entry in the /etc/defaults/fs file. HP-UX OS version 1 1.0 = vxfs 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 28: Creating The Mount Directories
Example # pvchange -t 60 /dev/dsk/c0t6d0 Physical volume "/dev/dsk/c0t6d0" has been successfully changed. Volume Group configuration for /dev/vg06 has been saved in /etc/lvmconf/vg06.conf. Verify that the new I/O timeout value is 60 seconds using the pvdisplay command: Example # pvdisplay /dev/dsk/c0t6d0 --- Physical volumes --- PV Name /dev/dsk/c0t6d0...

Page 58: Defining The Paths
IMPORTANT: For optimal performance when configuring any XP disk array with a Tru64 host, HP does not recommend: Sharing of CHA (channel adapter) microprocessors Multiple host groups sharing the same CHA port NOTE: As illustrated in “Microprocessor port sharing (OpenVMS)” (page 58), there is no microprocessor sharing with 8-port module pairs.
Page 59: Setting The Host Mode For The Disk Array Ports
Path configuration for OpenVMS requires the following steps: Define one command device LUN per array and present it to the OpenVMS hosts across all connected paths. If host mode option 33 is not enabled, for all LUNs, determine the device number as follows (once OpenVMS sees the XP disks): OpenVMS device name ($1$dgaxxx), where xxx = CU with LDEV appended (Then convert the created number from hex to decimal)

Page 171: D Using Veritas Cluster Server To Prevent Data Corruption
D Using Veritas Cluster Server to prevent data corruption Using VCS I/O fencing By issuing a Persistent Reserve SCSI-3 command, VCS employs an I/O fencing feature that prevents data corruption from occurring if cluster communication stops. To accomplish I/O fencing, each node of VCS registers reserve keys for each disk in a disk group that is imported.

them as described previously, you can then use them to create dynamic volumes and file systems, mount them on the cluster nodes, and assign drive letters or junction points. For details on importing and deporting disks, dynamic volume creation and configuration, and file system creation and configuration, see the HP StorageWorks Scalable NAS File Serving Software Administration Guide .
Page 178: Snapshots
Snapshots To take hardware snapshots on XP storage arrays, you must install the latest version of firmware on the array controllers. Also, the latest versions of XP Business Copy and XP Snapshot must also be installed on the array controllers. On the servers, you must install and configure the latest version of RAID Manager, with both local and remote HORCM instances running on each server, and with all file system LUNs (P-VOLs) controlled by the local instance and all snapshot V-VOLs (S-VOLs) controlled by the remote instance.
