Disk Array XP operating system configuration guide: Tru64 UNIX 7

8Preface

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. The storage capacity for each model is listed below:
XP128: From8to128drivesforupto36TB,48FCports
XP1024: From8to1024drivesforupto149TB,64FCports
XP10000: Up to 240drivesforupto69.2TB,48FCports
XP12000: Up to 1152 drives for up to 332 TB, 128 FC ports
•Server support. PCI-based AlphaStation or AlphaServer
•Operating system support. Tru64 UNIX, versions 4.0F/G or 5.1A/B with latest
supported patches
Conform the environment to these requirements before installing the array:
•Host Bus Adapters (HBAs) Install HBAs and all utilities and drivers. Refer to the
adapter documentation for installation details
•(Recommended) HP StorageWorks Remote Web Console XP, Command View
XP Advanced Edition or Command View XP with LUN management feature for
configuring disk array ports and paths
•(Recommended) HP StorageWorks LUN Configuration and Security Manager XP
•(Optional) OtheravailableXPsoftware(somemaynotbesupportedbyyour
system):
HP StorageWorks Business Copy XP
HP StorageWorks Continuous Access XP
HP StorageWorks Continuous Access Extension XP
HP StorageWorks Auto LUN XP
HP StorageWorks Data Exchange XP

Fibre Channel interface
The XP family of disk arrays supports these Fibre Channel elements:
•Connection speed of 1 Gbps and 2 Gbps
•Short-wave non-OFC (open fiber 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.
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.
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
volumesisdesignatedasOPEN-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.)
•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.
10 Installation

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 verson 5 fully supports dynamic load balancing and failover when multiple HBAs
are connected to the same LUN. This feature is ONLY available with version 5. On
Tru64 version 4, DO NOT connect multiple HBAs to the same LUN and DO NOT allow
the same LUN tobeaccessiblefrommultipleHBAsonTru64version4hosts.ONthe
version 4 system, this will allow multiple device names to access the same LUN. If both
device names are used, data corruption will result.
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 Remote Web Console
XP, Command View XP, or Command View XP Advanced Edition. Refer to the applicable
user’s guide for procedures.
RAID Manager command devices
RAID Manager manages Business Copy (BC) or Continuous Access (CA) operations
from a host server. To use RAID Manager with BC or CA, you use Remote Web Console,
Command View, or Command View XP Advanced Edition 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.

12 Installation

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.
The following restrictions apply when configuring any XP disk array with a Tru64 host:
•When an XP port is assigned to Tru64, that port may not be shared with any
other operating system.
•Multiple Tru64 hosts may share the same XP port.
•Sharing of CHA microprocessors is not recommended.
Disk Array XP operating system configuration guide: Tru64 UNIX 13

Setting the host mode for the disk array ports
After the disk array is installed, you must set the host mode for each disk array port to
match the host OS. Set the host mode using LUN Manager in Remote Web Console XP
(shown), Command View XP, or Command View XP Advanced Edition. 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.
14 Installation

For the XP1024/XP128 arrays, the host mode can also be set at the port information
window in Command View XP AE.
Disk Array XP operating system configuration guide: Tru64 UNIX 15

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.
Fibre Address
In fabric environments, the port addresses are assigned automatically. In arbitrated
loop environments, set the port addresses by selecting a unique arbitrated loop
physical address (AL-PA) or loop ID for each port. For specificvalues,refertotheHP
StorageWorks LUN Configuration and Security Manager XP User Guide.
16 Installation

Fabric and Connection parameter settings
Set each array port to FABRIC ON or OFF with connections of POINT-TO-POINT or FC-AL
asshowninthefollowingtableandfigures. For detailed topology information, refer to
the HP StorageWorks SAN Design Reference Guide on the www.hp.com web site.
Fabric Parameter Connection Parameter Provides
ON FC-AL NL-port (fabric loop port)
ON Point-to-Point N-port (fabric port)
OFF FC-AL NL-port (private arbitrated
loop)
OFF Point-to-Point Not supported
Disk Array XP operating system configuration guide: Tru64 UNIX 17

Install and configure the host
This section explains how to install and configure the host and host bus adapters (HBAs)
that connect the host to the disk array.
Loading the OS 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 HBA
manufacturer.
Installing and configuring the HBAs
Install and configure the host bus adapters using the HBA manufacturer’s instructions.
Set HBA loop or fabric mode
Set the HBAs to run in arbitrated loop mode or in fabric mode as follows.
1. Set the Tru64 UNIX console to diagnostic mode.
P00>>>set mode diag
2. Display the HBA configuration.
P00>>>wwidmgr -show adapter
3. Set the HBA topology to fabric or loop. The 9999 qualifier sets all adapters with
one command.
P00>>>wwidmgr -set adapter -item 9999 -topology loop
OR
P00>>>wwidmgr -set adapter -item 9999 -topo fabric
18 Installation

Configuring system files
Configure the Tru64 system to recognize the HBA as explained in the Tru64 Installation
Guide or New Hardware Delivery (NHD) kit. This usually consists of booting genvmunix
and executing doconfig(as explained in the Installation Guide). This can also sometimes
be done by editing the system kernel configuration file as explained below.
1. Edit the system kernel file to add a line defining the adapter.
Example
bus emx0 at pci0 slot3
controller scsi5 at emx0 slot0 <— Add this line
2. (Tru64 v4 only) Edit the /sys/data/cam_data.c system file to change the I/O
timeout value from 10 to 60.
u_long cdisk_to_def = 60
3. (Tru64 v4 only) Edit the TID in the emx_data.c file. The WWN that the host
recognizes is displayed in a configuration file, such as /etc/emx.info.Inthisfile, if
the target ID for a WWN is equal to or greater than 8,copyitintotheemx_data.c
file and change the target ID to a value between 0 and 7.
4. Use the doconfig-cconfig_file command to reconfigure the kernel, where config_file
is usually the system name.
5. Shut down and reboot the system.
If system boot fails, reboot with a backup copy of the kernel and check the edited
files for errors.
(Tru64 v5 only) When you add a new HBA after an HBA of the same type has
already been installed, a simple reboot causes the host to recognize the new HBA.
No rebuilding or reconfiguration is required.

Setting up 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.
Within the Storage Area Network (SAN), the clusters may be homogeneous (all the
same operating system) or they may be heterogeneous (mixed operating systems). How
you configure LUN security and fabric zoning depends on the operating system mix and
the SAN configuration.
