Disk Array XP operating system configuration guide: IBM AIX 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 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. IBM RS/6000 series, POWERstation, POWERserver, or SP series
•Operating system support. IBM AIX OS with current OS patches
Before installing the array, conform the environment to these requirements:
•Superuser access. Make sure you have superuser (root) access
•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

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 opticalcableswithSCorLCconnectors
•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.
Failover
The disk arrays support many standard software products that provide host, application,
or I/O path failover and management.
10 Installation

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 service processor
(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.

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 applicable
to your array.
