Fibre Channel interface

The XP family of disk arrays and the SVS200 support these Fibre Channel elements:

• Connection s

• Short-wave non-OFC (open ﬁber control) optical interface

• Multimode optical cables with SC or LC connectors

• Public or pr

Even tho ug h the interface is Fibre Channel, this guide uses the term “SCSI disk” because disk array devices are deﬁned to the host as SCSI d isks.

ivate arbitrated loop (FC-AL) or direct fabric attach

Device emulation types

TheXPfamilyofdiskarraysandtheSVS200supportthesedeviceemulationtypes:

• OPEN-3/8/9/E/L/V devices: OPEN-x logical units represent disk devices. Except for OPEN-V,

these devices are based on ﬁxed sizes. OPEN-V is a user-deﬁnedsize. Supportedemulations include OPEN-3, OPEN-8, OPEN-9, OPEN-E, OPEN-L, and OPEN-V devices.

• LUSE devices (OPEN-x*n): Logical U nit Size Expansion (LUSE) devices combine 2 to 36 OPEN-x

devices to create expanded LDEVs larger than standard OPEN-3/8/9/E/L/V 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.)

• LUSE (expanded) CVS devices (OPEN-x*n CVS): LUSECVScombinesCVSdevicestocreatean

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

NOTE:

For the SVS200, and the 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 external storage LDEVs to be conﬁgured without losing data. Using any other emulation may cause data loss in the external storage LUNs.

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

Installation

SNMP conﬁguration

The XP family of disk arrays and the SVS200 support standard Simple Network Management Protocol (SNMP) for remotely managing arrays. 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 Command View (XP arrays only), Remote Web Console, 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 RA with Command View (XP arrays only), Remote Web Console , or Command View XP Advanced Edition. Refer to the applicable user guide for information about how to designate a command device.

ID Manager you must designate at least one LDEV as a command d evice. This can be done

Fabric zonin

By using appropriate zoning and LUN security, you can connect various servers with various operating systems to the same switch and fabric:

• Storage port zones may overlap if more than one o perating system needs to share an array port.

• H eterogene

the appropriate host group and mode. All others must connect to a dedicated XP array port.

• Use Secure Ma n ager for LUN isolation when multiple hosts connect through a shared array

port. Secu can a ccess.

• QLogic and Emulex HBAs must be in separate zones (a QLogic zone and an Emulex zone)

whether t

• If booting over the SAN, within a server, the booting HBAs must be from the same vendor.

Additional data storage HBAs can be from a different vendor.

• 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

array.

Installation

Connect the disk array

The HP representative connects the cables between the array and the host or between the array and the SAN.

Deﬁning the paths

Use Remote Web Console (shown), Command View (XP arrays only), or Command View XP Advanced Edition to deﬁne paths (LUNs) between hosts and volumes in the disk array.

This process is also called “LUN mapping.” In Remote Web Console and Command View, LUN mapping includes:

• Conﬁguring ports

• Enabling LUN security on the ports

• Creating host groups

• Assigning host bus adapter WWNs to host groups

• Mapping volumes to host groups (by assigning LUNs

In Command View XP Advanced Edition, LUN mapping includes:

• Conﬁguring ports

• Creating storage groups

• Mapping volumes and WWN/host access permissions to the storage groups

For details see the LUN Conﬁg uration and Security Manager User’s Guide or Command View XP Advanced Edition Device Manager Web Client User’s Guide. Note the LUNS and their ports, WWNs, nicknames, and LDEVs for later use in verifying host and device conﬁguration.

HBA Host bus adapter.

host mod e Each port can

be conﬁgured for a particular host t ype. These modes are represented as two-digit hexadecimal numbers. For example, host mode 08 represents an HP-UX host.

LDEV Logical device. An LDEV is created when a R AID group is carved into pieces

according to the selected host emulation mode (that is, OPEN-3, OPEN-8, OPEN-L). The number of resulting LDEVs depends on the selected emulation mode. The term LDEV is often used synonymously with the term volume.

LUN Logical unit number. A LUN results from mapping a SCSI logical unit number,

port ID, and LDEV ID to a R A I D group. The size of the LUN is determined by the emulation mode of the LDEV and the number of LDEVs associated with the LUN.

example, a LUN associated with two OPEN-3 LDEVs has a size of 4,693 MB.

For

LUSE A LUN is normally associated with only a single LDEV. The LUSE feature allows

a LUN to be associated with 1 to 36 LDEVs. Essentially, LUSE makes it possible for applications to access a s ingle large pool of storage. The LUSE feature is available when the H P StorageWorks LUN Conﬁguration and Security Manager product is installed.

OFC Open Fibre Control.

OPEN-

A general term describing any one of the supported OPEN emulation modes (for example, OPEN-L).

OS Operating system.

PA Physical address.

path “Path” and “LUN” are synonymous. Paths are created by associating a port, a

target, and a LUN ID with one or more LDEVs.

port A physical connection that allows data to pass between a host and the disk

array. The number of ports on an XP disk array depends on the number of supported I/O slots and the number of ports available per I/O adapter. The XP family of disk arrays supports Fibre Channel (FC) ports as well as other port types. Ports are named by port group and port letter, such as CL1-A. CL1 is the group, and A is the port letter.

TB Terabyte.

TID Target ID.

Volume On the XP array, a volume is a uniquely identiﬁed virtual storage device

composed of a control unit (CU) component a nd a logical device (LDEV) component separated by a colon. For example 00:00 and 01: 00 are two uniquely identiﬁed volumes; one is identiﬁedasCU=00andLDEV=00,and the other as CU = 01 and LDEV = 00; they are two unique separate virtual storage devices within the XP array.

VSC Volume size customization. Synonymous with CVS.

WWN World Wide Name. A unique identiﬁer assigned to a Fibre Channel device.
