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
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
HP StorageWorks Resource Manager 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 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.
