Disk Array XP operating system configuration guide: Linux 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. Server supported by HP to run Linux. Consult your HP
representative for a list of supported servers.
•Operating system support. Red Hat, SuSE, and United Linux are supported.
Before installing the disk array, ensure the environment conforms to these requirements:
•Fibre Channel Port configuration Configure each Fibre Channel port on the
disk array so it has a unique Fibre Channel loop ID. (All ports are set to 0 by
default at the factory.)
•Linux version Confirm you are using Red Hat, SuSE, or United Linux.
•Superuser access Make sure you have superuser (root) login access to the Linux
system.
•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.)
