1 Installing and configuring Tru64 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.
Features and requirements
The disk array has the following features:
• Storage capacity: The storage capacity for each model is listed below:
XP10000: Up to 240 drives for up to 69.2 TB, 48 FC ports
XP12000: Up to 1152 drives for up to 332 TB, 128 FC ports
XP20000: Up to 240 drives for up to 69.2 TB, 48 FC ports
XP24000: Up to 1152 drives for up to 332 TB, 256 FC ports
• Server support: PCI-based AlphaStation or AlphaServer
• Operating system support: For supported disk array microcode and OS versions, see the HP
StorageWorks Single Point of Connectivity Knowledge (SPOCK):
h
ttp://spock.corp.hp.com
Before installing the disk array, ensure the following requirements are met:
• Fibre Channel Adapters (FCAs): Install FCAs and all utilities and drivers. Refer to the adapter doc-
umentation for installation details.
• HP StorageWorks XP Remote Web Console, or HP StorageWorks XP Command View with LUN
management feature for configuring disk array ports and paths.
• HP StorageWorks XP Array Manager.
• 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 SC or LC connectors
• 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.
XP Disk Array Configuration Guide for Tru64 UNIX 7
Device emulation types
The XP 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).
NOTE:
For the XP24000/XP20000/XP12000/XP10000 when 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 may cause
data loss in the external storage LUNs. For new deployments, OPEN-V should be chosen because
some features (such as XP Snapshot or Continuous Access Journal) are only supported with OPEN-V.
Refer to Table 8 on page 29 for detailed information.
Failover
The XP family of disk arrays supports many standard software products that provide host, application,
or I/O path failover and management. TruCluster is one of the supported applications.
CAUTION:
Tru64 5.1B and later fully support dynamic load balancing and failover when multiple FCAs are
connected to the same LUN. This feature is ONLY available with version 5.1B and later.
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 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. For procedures, refer to the
applicable user guide available at:
Installing and configuring Tru64 for the XP disk array8
http://www.hp.com/support/manuals.
Figure 1 SNMP configuration
XP RAID Manager command devices
HP StorageWorks XP RAID Manager manages HP StorageWorks XP Business Copy Software or HP
StorageWorks XP Continuous Access Software operations from a host server. To use XP RAID Manager
with XP Business Copy Software or XP Continuous Access Software, you use XP Remote Web Console
or XP Command View, to designate at least one LDEV as a command device. Refer to the applicable
user's guide for information about how to designate a command device.

• Creating the file systems
• Creating mount directories
• Mounting the file systems
• Verifying the file systems
• Setting and verifying automatic mounting at bootup
XP Disk Array Configuration Guide for Tru64 UNIX 9
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
• Configuring array groups and creating LDEVs
After these tasks are finished, use XP Remote Web Console, XP Command View, or XP Array Manager
to complete the remaining tasks listed below. For procedures, refer to the applicable user guide
available at:
http://www.hp.com/support/manuals.
If you do not have these programs, your HP service representative can perform these tasks for you.
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 the following table, there is no microprocessor sharing with 8–port module pairs.
With 16– and 32–port module pairs, alternating ports are shared.

Installing and configuring Tru64 for the XP disk array10
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. For procedures, refer to the applicable user guide available
at http://www.hp.com/support/manuals. If these are not available, the HP service representative
can set the host mode using the SVP.
The required host mode setting for Tru64 is 07.
CAUTION:
The correct host mode must be set for all new installations (newly connected ports) to Tru64 hosts. Do
not select a mode other than 07 for Tru64. 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) may be configured. The
storage administrator must verify if an additional host group mode is required for the host group.
XP Disk Array Configuration Guide for Tru64 UNIX 11
The following host group mode (option) is available for Tru64:

CommentsDefaultFunction

CAUTION:
Changing host group modes for ports where servers are already installed and configured breaks all
LUN paths and will require the paths to be redefined. See “Defining the paths” on page 16. If host
group mode 14 is applied to an existing LUN, Tru64 will need to be installed again. If XP Continuous
Access is going to be used, the host group mode must be set before the installing Tru64.
Enable use of XP Continuous Access Software
on Tru64 TruClusters.
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. Notify your HP representative if you install storage agnostic software
(such as backup or cluster software) that may require specific settings.
Configuring the Fibre Channel ports
Configure the disk array Fibre Channel ports by using Remote Web Console (shown), or XP Command
View. 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. For detailed
procedures, refer to HP StorageWorks XP LUN Manager User's Guide available at:
