MPX200 Multifunction Router Release Notes

HP Part Number: 5697-0950

Published: May 2011

Edition: Tenth

Version: 8.0

Description

The HP StorageWorks Enterprise Virtual Array (EVA) and XP families of Fibre Channel (FC) storage

systems are supported for integrated iSCSI connectivity using the MPX200 Multifunction Router.

The MPX200 hardware is integrated with up to four EVA or XP24000/20000 storage systems

and HP StorageWorks Command View EVA (EVA only) to deliver multiprotocol capabilities. This

provides iSCSI and FC-attached servers access to block storage through an FC and Ethernet/IP

network simultaneously.

The MPX200 supports multiple functions including iSCSI, FCoE (10 GbE models), FCIP, and online

or offline block-based data migration. FCIP and data migration are license-enabled features (see

Product models). The MPX200 functions are supported separately or simultaneously as follows:

•iSCSI and/or FCoE only

•FCIP only (license required)

•Data migration only (license required)

•iSCSI/FCoE and FCIP (license required)

•iSCSI/FCoE and data migration (license required)

For more information about MPX200 simultaneous operation, see the MPX200 Multifunction Router

User Guide. For more information on data migration, see the HP StorageWorks MPX200

Multifunction Router Data Migration Solution Guide.

Product models

The following models and licensed features of the MPX200 Multifunction Router are available:

•HP StorageWorks MPX200 Multifunction Router 1 GbE base chassis (AP771A)—Order with

•HP Storage Works MPX200 Full Chassis 1 Array Data Migration License (TA764A)—Includes

the license to migrate data from or to a single array using a MPX200 Chassis

NOTE: The MPX200 data migration has a unique fan-in/fan-out licensing model. Using this

particular license, data can be migrated from multiple arrays to a single array or from a single

array to multiple arrays.

•HP Storage Works MPX200 Full Chassis 3 Array Data Migration License (TA765A)—Includes

the license to migrate data from or to a single array, on three unique migration jobs using a

MPX200 Chassis

NOTE: The MPX200 data migration has a unique fan-in/fan-out licensing model. Using this

license, data can be migrated from multiple arrays to a single array or from a single array to

multiple arrays, three times; that is, this license can enable three different migration jobs using

the same MPX200 Chassis at different times.

The following equipment is required to configure the MPX200 Multifunction Router:

•B-series or C-series FC switch (fabric-attached only)

•Optical small form-factor pluggable (SFP) transceivers:

FC ports, 8 Gb/s short range SFP (AJ718A)◦

◦FC ports, 4 Gb/s short range SFP (A7446B)

◦10 GbE ports, short range SFP+ (455883-B21)

•Optical FC cables (fabric-attach or direct-connect)

•Copper FC cables (direct-connect only)

•Cat5e or Cat6 GbE Ethernet network cables

Purpose of the update

The MPX200 firmware version for this release is 3.3.0.2. This release includes the following

updates:

•Fixes for the iSCSI, FCIP, FCoE, and data migration functions. See “Fixes” (page 5).

Fixes

The following fixes have been implemented in firmware version 3.3.0.2:

•iSCSI fixes: LUN presentation failed with the error message “Virtual disk operation has failed.

Ensure that the FC target connections are online.”

LUN information is now refreshed prior to presentation.

•FCIP fix: IP address validation did not occur. Proper address validation is now performed on

IP addresses and Gateway address, taking subnet mask into account.

•FCoE fix: FCoE initiators were presented as Fibre Channel initiators, preventing Command

View EVA from presenting LUNs to FCoE hosts.

•Data Migration fix: Previously when the SPC-2 option was not set on an EMC DMX array FA

port and a WWLUNID size greater than 64 bytes was reported, the rpcserver would crash.

The LUN WWLUNID now truncates to 64 bytes.

Prerequisites

HP Command View EVA—The MPX200 requires HP Command View EVA version 9.2 or later.

FCoE requires Command View EVA 9.3 or later.

Installation instructions

For information about installing the MPX200 Multifunction Router, see the HP StorageWorks

MPX200 Multifunction Router EVA iSCSI Quick Start Instructions for Microsoft Windows, the HP

StorageWorks Multifunction Router FCIP Quick Start Instructions, and the HP StorageWorks MPX200

Multifunction Router User Guide, available on the HP Manuals website:

http://www.hp.com/support/manuals

Under Storage, click Storage Networking, and then under Routers/Gateways/Multiplexers, select

HP StorageWorks MPX200 Multifunction Router.

Important notes

FCoE notes

Command View EVA auto-presented offline targets

In a configuration with multiple MPX200 Multifunction Routers (different chassis enclosures) within

the same FC zone, auto-presented offline targets for the FCoE ports will display under the Command

View EVA iSCSI controller FC Ports tab.

LUN 0 presentation for MPX200 FCoE/iSCSI target

When managing an EVA using an FCoE/iSCSI CNA-based server with MPX200 FCoE/iSCSI

target connectivity, un-presenting the last FCoE/iSCSI LUN from the MPX200 FCoE/iSCSI Controller

may cause Command View to lose communication with the array. To resolve this problem, use the

Fixes 5

MPX200 CLI to present LUN 0 from each EVA Fibre Channel target WWN to each of the MPX200

FCoE/iSCSI ports, and to each of the management server's FCoE/iSCSI CNA ports. If you use a

dual-blade MPX200 chassis, you must execute this presentation process for both MPX200 Blades.

Data migration notes

iSCSI notes

Management of the MPX200 iSCSI configuration with XP24000/20000 storage systems is provided

through the mpx Manager software or the MPX200 CLI. The mpx Manager software is available

at: http://hp.com/go/mpx200.

Mac server sleep mode

The ATTO Mac iSCSI Initiator does not support Mac server sleep mode. If sleep mode is enabled,

and the Mac server goes to sleep, the initiator can lose iSCSI connectivity to the logical unit numbers

(LUNs).

If the ATTO Mac iSCSI Initiator is installed, disable Mac server sleep mode.

Windows drops the IP connection

Certain I/O workloads can cause Windows to drop the IP connection, resulting in removal of a

LUN.

To restore the IP connection, reboot the system. To avoid dropped connections:

•Reduce the I/O workload.

•Reduce the application transfer size.

Windows registry modifications

CAUTION: Use the Registry Editor at your own risk. Using it incorrectly can cause serious problems

that require reinstallation of the operating system. Be sure to back up the registry before making

any changes.

If you use a method other than the HP StorageWorks MPX200 Multifunction Router Windows

software kit to update, you add the Tcp1323Opts and Disk TimeOutValue to the registry.

Timestamps enable TCP to accurately measure round-trip time (RTT) to adjust retransmission timeouts.

The timestamps option provides two 4-byte timestamp fields in the TCP header. One field records

the time of the initial transmission; the other field records the time on the remote host.

There are two methods to add Tcp1323Opts to the registry. HP recommends that you use the first

method.

IMPORTANT: When you install the Windows iSCSI initiator from the HP StorageWorks MPX200

Multifunction Router Windows software kit, Tcp1323Opts is added to the registry automatically.

Method 1

To enable timestamps, under:

HKLM\SYSTEM\CurrentControlSet\Services\Tcpip\Parameters, set the Tcp1323Opts

entry to REG_DWORD = 2.

To extend the timeout period, under: HKLM\System\CurrentControlSet\services\Disk,

set the TimeOutValue entry to REG_DWORD = 120.

Method 2

Make the change to the registry, or cut and paste the following lines to a text file named:

tcp1323opts.reg:

tcp1323opts.reg.

REGEDIT4

[HKEY_LOCAL_MACHINE\SYSTEM\Current-

ControlSet\Services\Tcpip\Parameters]

"Tcp1323Opts"=dword:00000002

Double-click the tcp1323opts.reg file to add the changes to the registry for the iSCSI initiator.
