◦ OpenVMS server support: PCI-based AlphaServers; PCI-based Integrity (IA64) Servers.
◦ VMware server support: VMware-supported processor.
◦ Windows server support: Windows PC server with the latest HP supported patches.
• Operating system support: For supported disk array microcode and OS versions, see the HP
SPOCK website: http://www.hp.com/storage/spock.
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 P9000 Remote Web Console or HP StorageWorks P9000 Command View
Advanced Edition Suite Software for configuring disk array ports and paths.
10 Overview
• HP StorageWorks P9000 Array Manager Software
• Check with your HP representative for other P9000 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. Integrity servers have no minimum firmware version requirement.
• HP does not support using Command View Advanced Edition Suite Software from a Guest
OS.
In addition, for Solaris, ensure the following requirements are aslo met before installing the disk
array:
• Volume Manager: Solaris Volume Manager or Veritas Volume Manager.
• Oracle SAN software: For Solaris 8/9 (if not using Emulex, QLogic, or JNI drivers), latest SAN
Foundation Software with current patches. For Solaris 10 (if not using Emulex, or QLogic
drivers), latest SAN (Leadville driver stack) with current patches.
Oracle StorEdge Traffic Manager/Oracle VM Storage Multipathing requires that you configure
/kernel/drv/scsi_vhci.conf.
For Solaris 8/9 SAN information, see Oracle StorEdge SAN Foundation Software & Installation
Guide and Oracle StorEdge Traffic Manager Software Installation and Configuration Guide
at www.oracle.com.
For Solaris 10 and later SAN information, see Solaris Fibre Channel and Storage Multipathing
Administration Guide at www.oracle.com.
Fibre Channel interface
The P9000 family of disk arrays supports the following Fibre Channel elements:
• Connection speeds of 2 Gbps, 4 Gbps, and 8 Gbps.
• Short-wave non-OFC (open fibre control) optical interface
• Multimode optical cables with SC or LC connectors
• Public or private arbitrated loop (FC-AL) or direct fabric attach
• 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.
Fibre Channel elements specific to NonStop:
• 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
Fibre Channel interface 11
Device emulation types
The P9000 family of disk arrays supports 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.
• LUSE devices (OPEN-x*n): Logical Unit Size Expansion (LUSE) devices combine 2 to 36 OPEN-x
devices to create expanded LDEVs larger than standard OPEN-x disk devices. For example,
an OPEN-x LUSE volume created from ten OPEN-x volumes is designated as OPEN-x*10.
• CVS devices (OPEN-x CVS): Volume Size Configuration (VSC) defines custom volumes (CVS)
that are smaller than normal fixed-sized logical disk devices (volumes). (OPEN-V is a CVS-based
custom disk size that you determine. OPEN-L does not support CVS.) Although OPEN-V is a
CVS-based device, the product name in the SCSI inquiry string is OPEN-V opposed to the
fixed size OPEN-[389E] devices that appear as OPEN-x-CVS.
• LUSE (expanded) CVS devices (OPEN-x*n CVS): LUSE CVS combines CVS devices to create
an expanded device. This is done by first creating CVS custom-sized devices and then using
LUSE to combine from 2 to 36 CVS devices. For example, if three OPEN-9 CVS volumes are
combined to create an expanded device, this device is designated as OPEN-9*3-CVS. OPEN-V
devices are designated as OPEN-V*n (without CVS).
• FX Devices (3390-3A/B/C, OPEN-x FXoto): The Data Exchange feature allows you to share
data across mainframe, UNIX, and PC server platforms using special multi-platform volumes.
The VLL feature can be applied to DE devices for maximum flexibility in volume size.
(FX Devices—Not applicable to NonStop, Novell Netware, OpenVMS, and VMware)
NOTE: When the P9500 is connected to external storage devices, HP recommends using OPEN-V
as the emulation the array makes visible to the host. This allows configuration of external storage
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 StorageWorks P9000 Snapshot Software or HP StorageWorks P9000 Continuous Access
Journal Software) are only supported with OPEN-V.
For detailed information, see “Emulation specifications (HP-UX)” (page 117).
Failover
Depending on the operating system used, the disk arrays support many standard software products
that provide host, application, or I/O path failover, and management.
HP-UX
• HP Multi-Computer/Serviceguard (MC/Serviceguard) software for application failover
• Alternate link for I/O path failover (included in HP-UX)
• Logical volume management (included in HP-UX)
OpenVMS
The P9000 family of disk arrays is supported with OpenVMS's resident Multipath software, which
provides I/O path failover.
Solaris
• The Veritas Cluster Server, Solaris Cluster, and Fujitsu Siemens Computers PRIMECLUSTER
host failover products are supported for the Solaris operating system. See the documentation
for these products and Oracle technical support for installation and configuration information.
12 Overview
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. HP supplies HDLM. All these products provide multipath
configuration management, FCAs I/O load balancing, and automatic failover support, however
their level of configuration possibilities and FCAs support differs.
• For instructions on STMS, Storage Multipathing, or VxVM, see the manufacturers' manuals.
SNMP configuration
The P9000 family of disk arrays supports standard SNMP for remotely managing arrays. The
SNMP agent on the 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 or Command View Advanced Edition Suite Software. For specific procedures, see the
applicable user guide.
Figure 1 SNMP configuration
RAID Manager command devices
The following applies to OpenVMS, HP-UX, IBM AIX, Linux, Solaris, VMware, and Windows.
• HP StorageWorks P9000 RAID Manager Software manages HP StorageWorks P9000 Business
Copy Software or HP StorageWorks P9000 Continuous Access Synchronous Software
operations from a host server. To use RAID Manager, you must designate at least one LDEV
as a command device. This can be done with Remote Web Console or Command View
Advanced Edition Suite Software. For information about how to designate a command device,
see the applicable user guide.
• Creating scripts to configure all devices at once could save you considerable time.
The following applies to OpenVMS.
When creating a command device, HP recommends creating a LUN 0 device of 35 megabytes
(the smallest allowed). This allows you to use host-based RAID management tools available from
HP, and will allow HP support to perform some additional diagnostics.
NOTE: Storage assigned to the LUN 0 device is not accessible to OpenVMS.
SNMP configuration 13
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.
Installation roadmap
Perform these actions to install and configure the disk array:

• “Defining the paths” (page 15)
• “Setting the host mode and host group mode for the disk array ports” (page 15)
• “Setting the system option modes” (page 15)
• “Configuring the Fibre Channel ports” (page 16)
2. “Installing and configuring the host” (page 16)
• “Loading the operating system and software” (page 16)
• “Installing and configuring the FCAs ” (page 16)
• “Clustering and fabric zoning” (page 16)
• “Fabric zoning and LUN security for multiple operating systems” (page 17)
3. “Connecting the disk array” (page 17)

• “Creating the mount directories” (page 27)
• “Mounting and verifying the file systems” (page 27)
• “Setting and verifying the auto-mount parameters” (page 28)
Installing and configuring 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, use Remote Web Console, Command View Advanced Edition, or
Array Manager to complete the remaining disk array configuration tasks. If you do not have these
programs, your HP service representative can perform these tasks for you.
14 HP-UX
Defining the paths
Use Command View Advanced Edition or Remote Web Console to define paths between hosts
and volumes (LUNs) in the disk array.
This process is also called “LUN mapping.” In the Remote Web Console, LUN mapping includes:
• Configuring ports
• Enabling LUN security on the ports
• Creating host groups
• Assigning Fibre Channel adapter WWNs to host groups
• Mapping volumes (LDEVs) to host groups (by assigning LUNs)
In 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 the HP StorageWorks P9000 Provisioning for Open Systems User Guide. Note the
LUNs and their ports, WWNs, nicknames, and LDEVs for later use in verifying host and device
configuration.
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 Remote Web
Console or Command View Advanced Edition. If these are not available, the HP service
representative can set the host mode using the SVP. The host mode setting for HP-UX is 08.
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. The
storage administrator must verify if an additional host group mode is required for the host group.
The following host group modes (options) are available for HP-UX:

CAUTION: Changing host group modes for ports where servers are already installed and
configured is disruptive and requires the server to be rebooted.
Setting the 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 2
(page 50) enable storage system behaviors that are more compatible with the requirements of a
NonStop system than the default modes. Ask your service representative if these modes apply in
your situation.

Configuring the Fibre Channel ports
Configure the disk array Fibre Channel ports by using Command View Advanced Edition or 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.
Installing and configuring the host
This section explains how to install and configure Fibre Channel adapters (FCAs) that connect the
host to the disk array.
Loading the operating system and software
Follow the manufacturer's instructions to load the operating system and software onto the host.
Load all OS patches and configuration utilities supported by HP and the FCA manufacturer.
Installing and configuring the FCAs
Install and configure the Fibre Channel adapters using the FCA manufacturer's instructions.
Clustering and fabric zoning
If you plan to use clustering, install and configure the clustering software on the servers.
Clustering is the organization of multiple servers into groups. Within a cluster, each server is a
node. Multiple clusters compose a multi-cluster environment. The following example shows a
multi-cluster environment with three clusters, each containing two nodes. The nodes share access
to the disk array.
16 HP-UX
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:
• Storage port zones can overlap if more than one operating system needs to share an array
port.
• Heterogeneous operating systems can share an array port if you set the appropriate host
group and mode. All others must connect to a dedicated array port.
• Use LUN Manager for LUN isolation when multiple hosts connect through a shared array port.
LUN Manager provides LUN security by allowing you to restrict which LUNs each host can
access.

Connecting the disk array
The HP service representative performs the following steps to connect the disk array to the host:
1. Verifying operational status of the disk array channel adapters, LDEVs, and paths.
2. Connecting the Fibre Channel cables between the disk array and the fabric switch or host.
3. Verifying the ready status of the disk array and peripherals.
Verifying FCA installation
After configuring the ports on the disk array, verify that the FCAs are installed properly.
Connecting the disk array 17
Use the ioscan –f command, and verify that the rows shown in the example are displayed. If
these rows are not displayed, check the host adapter installation (hardware and driver installation)
or the host configuration.

Verifying device recognition
Verify that the HP-UX system recognizes the new devices on the disk array.
If the SCSI paths were defined after the system is powered on, you must halt and restart the system
to allow the system to recognize the new devices.
To verify device recognition:
1. Log in to the system as root.
2. Display the device data to verify that the system recognizes the newly installed devices on the
disk array. Use the ioscan –fn command to display the device data.
On a system with a large LUN configuration, HP-UX cannot build device files on all LUNs.
Enter insf –e to build all missing device files.
Example
# ioscan -fn

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.
• If UNKNOWN is displayed for a disk, the HP 9000 system might be configured properly.
See the HP documentation or contact HP customer support for assistance with the HP
9000 system or the HP-UX operating system.
3. Enter the device data for each disk array device in a table. See “Path worksheet” (page 115).
4. Construct the device file name for each device, using the device information, and enter the
file names in your table. Use the following formula to construct the device file name:
cxtydz
where:
• x = SCSI bus instance number
• y = SCSI target ID
18 HP-UX
• z = LUN
• c stands for controller
• t stands for target ID
• d stands for device
The numbers x, y, and z are hexadecimal.
Table 4 Device file name example (HP-UX)
File nameLUNSCSI TIDHardware pathSCSI bus instance
number
c6t0d00614/12.6.000
c6t0d12614/12.6.100
5. Verify that the SCSI TIDs correspond to the assigned port address for all connected ports (see
mapping tables in SCSI TID map for Fibre Channel adapters (HP-UX), for values). If so, the
logical devices are recognized properly.
If the logical devices are not recognized properly:
• Check the AL-PA for each port using the LUN Manager software.
• If the same port address is set for multiple ports on the same loop (AL with HUB), all port
addresses except one changed to another value, and the relationship between AL-PA and
TID does not correspond to the mapping given in SCSI TID map for Fibre Channel adapters
(HP-UX), set a different address for each port, reboot the server, and then verify new
device recognition again.
• If unused device information remains, the TID-to-AL-PA mapping will not correspond to
the mapping given in SCSI TID map for Fibre Channel adapters (HP-UX). Renew the device
information, and then verify new device recognition again.
Configuring disk array devices
Disk arrays are configured using the same procedure for configuring any new disk on the host.
This includes the following procedures:
1. “Verifying the device files and drivers” (page 20)
2. “Creating the device files” (page 20)
3. “Creating the physical volumes” (page 22)
4. “Creating new volume groups” (page 22)
5. “Creating logical volumes” (page 24)
6. “Creating the file systems” (page 26)
7. “Setting the I/O timeout parameter” (page 26)
8. “Creating the mount directories” (page 27)
9. “Mounting and verifying the file systems” (page 27)
10. “Setting and verifying the auto-mount parameters” (page 28)
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.
HP System Administrator Manager (SAM) can be used instead of UNIX commands to configure
SCSI disk devices. See Reference information for the HP System Administrator Manager SAM for
further information. The newer releases of HP-UX have deprecated the SAM tool and replaced it
with the System Management Homepage (SMH) tool.
Configuring disk array devices 19
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. If verification
shows that the device files were not created, follow the instructions in “Creating the device files”
(page 20).
The following procedure verifies both types of device files:
1. Display the block-type device files in the /dev/dsk directory using the ls –l command with
the output piped to more. Verify there is one block-type device file for each disk array device.
Example
# ls –l /dev/dsk | more
Total 0
brw-r - - - - - 1 bin sys 28 0x006000 Dec 6 15:08 c6t0d0
brw-r - - - - - 1 bin sys 280 0x06100 Dec 6 15:08 c6t0d1
2. Verify that the block-type device file name for each device is correct.
3. Display the character-type device files in the /dev/rdsk directory using the ls –l command
with the output piped to more. Verify that there is one character-type device file for each disk
array device.
Example
# ls –l /dev/rdsk | more
Total 0
crw-r - - - - - 1 bin sys 177 0x006000 Dec 6 15:08 c6t0d0
crw-r - - - - - 1 bin sys 177 0x006100 Dec 6 15:08 c6t0d1
4. Use the device data table you created to verify that the character-type device file name for
each device is correct.
This task can also be accomplished with the lssf command.
5. After verifying the block-type and character-type device files, verify the HP-UX driver for the
disk array using the ioscan –fn command.
Example
# ioscan -fn

Creating the device files
If the device files were not created automatically when the system was restarted, use the insf
–e command in the /dev directory to create the device files. After this command is executed,
20 HP-UX
repeat the procedures in “Verifying device recognition” (page 18) 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:
1. Retrieve the device information you recorded earlier.
2. Construct the device file name for each device, using the device information, and enter the
file names in your table. Use the following formula to construct the device file name:
cxtydz
where:
• x = SCSI bus instance number
• y = SCSI target ID
• z = LUN
• c stands for controller
• t stands for target ID
• d stands for device
The numbers x, y, and z are hexadecimal.
3. Construct the minor number for each device, using the device information, and enter the file
names in your table. Use the following formula to construct the minor number:
0xxxyz00 where
xx = SCSI bus instance number, y = SCSI target ID, and z = LUN.
4. Display the driver information for the system using the lsdev command.
Example
# lsdev
Character Block Driver Class
: : : :
188 31 sdisk disk
#
5. Enter the major numbers for the device drivers into the table. You should now have all required
device and driver information in the table.
Configuring disk array devices 21
6. 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.
File name, b=block-type,
31=major #, 0x026000= minor #
# cd /dev/rdsk Go to /dev/rdsk directory.
# mknod /dev/rdsk/c2t6d0 c 188 0x026000 Create character-type file.
File name, c=character-type,
177=major #, 0x026000=minor #
:
#
The character-type device file is required for volumes used as raw devices (for example,
3390-3A/B/C). The block-type device file is not required for volumes used as raw devices.
If you need to delete a device file, use the rm –i command.

Creating the physical volumes
A physical volume must be created for each new SCSI disk device.
To create the physical volumes:
1. Use the pvcreate command to create the physical volumes with the character-type device
file as the argument. Specify the /dev/rdsk directory.
Example
# pvcreate /dev/rdsk/c6t0d0
Physical volume "/dev/rdsk/c6t0d0" has been successfully created.
:
# pvcreate /dev/rdsk/c6t0d1
Physical volume "/dev/rdsk/c6t0d1" has been successfully created.
Do not use the –f option with the pvcreate command. This option creates a new physical
volume forcibly and overwrites the existing volume. If you accidentally enter the character-type
device file for an existing volume, you will lose the data on that volume.
2. Repeat step 1 for each OPEN-x device on the disk array.
Creating new volume groups
You must create new volume groups for the new physical volumes. If desired, you can also add
any of the volumes on the disk array to existing volume groups using the vgextend command.
22 HP-UX
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.
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:
1. Use the vgdisplay command to display the existing volume groups.
2. Choose a unique name for the new volume group (for example: vg06).
3. Create the directory for the new volume group.
Example
# mkdir /dev/vg06
4. Use the ls –l command (with the output piped to grep to display only the files containing
“group”) to display the minor numbers for the existing group files.
Example
# ls –1 /dev/vg* | grep group
crw-rw-rw 1 root root 64 0x0000000 Nov7 08:13 group
:
5. Choose a unique minor number for the new group file in sequential order (for example, when
existing volume groups are vg00-vg05 and the next group name is vg06, use minor number
06 for the vg06 group file).
The minor numbers are hexadecimal (for example, the 10th minor number is 0x0a0000).
6. Use mknod to create the group file for the new directory. Specify the volume group name,
major number, and minor number. The major number for all group files is 64.
Example
In this example: group name = vg06, major number of group file = 64, minor number of
existing group file = 06 (which must be unique for each volume group), and c = character.
# mknod /dev/vg06/group c 64 0x060000
:
7. Create the volume group.
To allocate more than one physical volume to the new volume group, add the other physical
volumes, separated by a space.
Example
# vgcreate /dev/vg06 /dev/dsk/c6t0d0
Volume group "/dev/vg06" has been successfully created.
Volume group configuration for /dev/vg06 has been saved in
/etc/1vmconf/vg06.conf.
For Logical Unit Size Expansion (LUSE) volumes that contain more than 17 OPEN-8/9 LDEVs
or more than 7043 MB (OPEN-8/9*n-CVS), use the –s and –e physical extent (PE) parameters
of the vgcreate command. See LUSE device parameters.
If you need to delete a volume group, use the vgremove command (for example, vgremove
/dev/vgnn). If the vgremove command does not work because the volume group is not
active, use the vgexport command (for example, vgexport /dev/vgnn).
8. Use the vgdisplay command to verify that the new directory was created.
Configuring disk array devices 23
9. Use vgdisplay –v to verify that the volume group was created correctly. The –v option
displays the detailed volume group information.

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.
Example
lvextend –L size /dev/vgnn/lvolx
• lvreduce
Decreases the size of an existing logical volume. Any file system attached to the logical volume
must be unmounted before executing the lvreduce command.
Example
lvreduce –L size /dev/vgnn/lvolx
CAUTION: Data within the file system can be lost after execution of lvreduce.
Create logical volumes after you create volume groups. A logical volume must be created for each
new SCSI disk device.
24 HP-UX
To create logical volumes:
1. 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
OPEN-8 = 7004
OPEN-9 = 7004
OPEN-E = 13888
OPEN-L = 34756
OPEN-V = 61432
To calculate S1 for CVS, LUSE, and CVS LUSE volumes, first use the vgdisplay command
to display the physical extent size (PE Size) and usable number of physical extents (Free PE)
for the volume. Calculate the maximum size value (in MB) as follows:
S1 = (PE Size) × (Free PE)
Logical volumes can span multiple physical volumes. Use the diskinfo command for extended
LUNs.
2. Create an OPEN-3 logical volume the size of the physical volume, using 2344 for the size
parameter. An OPEN-9 volume uses 7040 for the size parameter to create a logical volume
the size of the physical volume.
Example
# lvcreate –L 2344 /dev/vg06
Logical volume "/dev/vg06/lvol1" has been successfully created with
character device "/dev/vg06/rlvol1".
Logical volume "/dev/vg06/lvol1" has been successfully extended.
Volume Group configuration for /dev/vg06 has been saved in
/etc/1vmconf/vg06.conf.
3. Use the lvdisplay command to verify that the logical volume was created correctly.
Example
# lvdisplay /dev/vg06/lvol1
- - - Logical volume - - LV Name /dev/vg06/lvol1
VG Name /dev/vg06

4. Repeat steps 1–3 for each logical volume to be created.
You can create only one logical volume at a time. However, you can verify multiple logical
volumes at a time.
Configuring disk array devices 25
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 11.0 = vxfs
• HP-UX OS version 11.i = vxfs
To create file systems:
1. Use the newfs command to create the file system using the logical volume as the argument.
Example 1
# newfs /dev/vg06/rlvol1
newfs: /etc/default/fs determine the file system type
mkfs (hfs): Warning -272 sectors in the last cylinder are not
allocated.
mkfs (hfs): /dev/vg06/rlvol1 - 2400256 sectors in 3847 cylinders

Example 2
# newfs /dev/vg06/rlvol1 create file system
newfs: / etc/default/fs determine the file system type

#
Example 3
# newfs -F vxfs /dev/vg06/rlvol1 Specify file system type
:
# newfs -F hfs /dev/vg06/rlvol2
2. Repeat step 1 for each logical volume on the disk array.
Setting the I/O timeout parameter
Set the I/O timeout value for each disk device to 60 seconds.
1. 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

Free PE 0
Allocated PE 586 [OPEN-9]
Stale PE 0
IO Timeout (Seconds) default [I/O timeout value]
2. If the I/O timeout value is not 60, change the value to 60 using the pvchange -t command:
26 HP-UX
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.
3. 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
VG Name /dev/vg06
PV Status available
:
Stale PE 0
IO Timeout (Seconds) 60 [New I/O timeout value]
4. Repeat steps 1–3 for each new disk connected to the system.
Creating the mount directories
Create a mount directory for each logical volume. Choose a unique name for each mount directory
that identifies the logical volume.
To create a mount directory for each logical volume:
1. Use mkdir with the new mount directory name as the argument to create the mount directory.
Example
# mkdir /AHPMD-LU00
2. Use the ls –x command to verify the new mount directory.
Example
The following example shows the root directory as the location for the mount directories.
# ls -x
AHPMD-LU00 bin dev device etc export
floppy home hstsboof kadb kernel lib
3. Repeat steps 1–2 for each logical volume on the disk array.
Mounting and verifying the file systems
After the mount directories have been created, mount and verify the file system for each logical
volume.
To mount and verify the file systems:
1. Use mount to mount the file system for the volume.
Example
# mount /dev/vg06/lvol1 /AHPMD-LU00
2. Repeat step 1 for each logical volume on the disk array.
If you need to unmount a file system, use the unmount command.
3. Use the bdf command to verify that the file systems are correct. The capacity is listed under
Kbytes.
Example
# bdf

4. As a final verification, perform some basic UNIX operations (for example file creation, copying,
and deletion) on each logical device to make sure that the devices on the disk array are fully
operational.
Example

Setting and verifying the auto-mount parameters
Set up and verify the auto-mount parameters for each new volume. The /etc/checklist file
(which can also be called the /etc/fstab file) contains the auto-mount parameters for the logical
volumes.
To set up and verify the auto-mount parameters:
1. Edit the /etc/checklist (/etc/fstab) file to add a line for each OPEN-x device on the
disk array. This example and the following table show the auto-mount parameters.
Example
#cp -ip /etc/checklist /etc/checklist.standard
#vi /etc/checklist
/dev/vg00/lvol1 / hfs rw 0 1 # root
/dev/vg00/lvol2 swap ignore rw 0 0 # primary swap
:
/dev/vg06/lvol1 /AHPMD-LU00 hfs defaults 0 2 # AHPMD-LU00
/dev/vg06/lvol2 /AHPMD-LU01 hfs defaults 0 2 # AHPMD-LU01

Configuring disk array devices 29
3 Windows
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.
Installation roadmap
Perform these actions to install and configure the disk array:
1. “Installing and configuring the disk array” (page 30)
• “Defining the paths” (page 30)
• “Setting the host mode and host group mode for the disk array ports” (page 31)
• “Setting the system option modes” (page 32)
• “Configuring the Fibre Channel ports” (page 32)
2. “Installing and configuring the host” (page 32)
• “Loading the operating system and software” (page 32)
• “Installing and configuring the FCAs ” (page 32)
• “Fabric zoning and LUN security” (page 33)
3. “Connecting the disk array” (page 33)
• “Verifying the host recognizes array devices” (page 34)
4. “Configuring disk devices” (page 34)
• “Writing signatures” (page 34)
• “Creating and formatting disk partitions” (page 35)
• “Verifying file system operations ” (page 35)
Installing and configuring 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, use Remote Web Console, Command View Advanced Edition, or
Array Manager to complete the remaining disk array configuration tasks. If you do not have these
programs, your HP service representative can perform these tasks for you.
Defining the paths
Use Remote Web Console or Command View Advanced Edition to define paths (LUNs) between
hosts and volumes in the disk array.
This process is also called “LUN mapping.” In Remote Web Console, LUN mapping includes:
• Configuring ports
• Enabling LUN security on the ports
• Creating host groups
• Assigning Fibre Channel adapter WWNs to host groups
• Mapping volumes (LDEVs) to host groups (by assigning LUNs)
