MPX200 features
The Enterprise Virtual Array (EVA) and XP families of Fibre Channel (FC) storage systems are supported for integrated iSCSI connectivity using the MPX200. The MPX200 hardware is integrated with up to four EVA or XP24000/20000 storage systems for iSCSI connectivity, to deliver multi-protocol capabilities. This provides iSCSI and FC attached servers access to block storage through an FC network and an Ethernet IP network simultaneously. Also, FCIP, FCoE, and data migration capabilities are available for use. For more information on data migration, see the HP StorageWorks MPX200 Multifunction Router D ata Migration Solution Guide.
The MPX200 is available from HP factory-integrated with an EVA or XP24000/20000 storage system or as a field upgrade to an existing storage system. iSCSI connectivity to the storage system is provided for servers through a standard 1-Gigabit Ethernet (GbE) or 10-GbE network interface controller (NIC).
The MPX200 chassis contains one or two router blades, two power cooling modules (PCMs), and a mid-plane. There are two types of router blades: a 4-port 1-GbE blade and a 2-port 10-GbE/2-port 1-GbE blade. Both blade options include two 8-Gb/s FC ports. MPX200 dual-blade configurations provide for high availability with failover between blades.
NOTE:
Each PCM has three variable-speed fans that provide power and cooling. You can remove and replace a PCM at any time. To ensure that the MPX200 chassis remains operational, there must be at least one functioning PCM. Each PCM is capable of powering two blades. The PCM cools the corresponding blade; therefore, when you remove a PCM, you must replace it within 7 minutes or the blade will shut down due to an over-temperature condition.

MPX200 configuration options for EVA
You can configure an EVA storage system for simultaneous connectivity to iSCSI and FC attached hosts. Support for iSCSI to an EVA is provided through the MPX200 and an FC switch fabric port (fabric attach) or the MPX200 directly connected to the EVA.
NOTE:
Directly connecting an MPX200 FC port and an EVA requires the EVA controller port to be set to Direct.
Figure 1 illustrates an MPX200 single-blade fabric-attached configuration. This is the lowest-cost
configuration and is used when high availability for iSCSI hosts is not required.

Simultaneous operation
You can configure the MPX200 chassis with a single blade or dual blades to run up to two oper­ations simultaneously per blade as shown in Table 2.
iSCSI operation
Dual-blade configurations are for high availability
Total number of initiators
Number of paths required per initiator
Use of Internet Storage Name Service (iSNS)
Use of iSCSI ports
Load balancing

Number of paths required per initiator
After establishing the number of initiators, determine how many paths are required by each. The number of connections per blade is finite, and every initiator login constitutes a connection to the MPX200. In a multipath environment, HP recommends a minimum of one connection per blade; high-performance applications may require up to four connections per blade (a total of eight).
Use of iSNS
The MPX200 presents one iSCSI target for each virtual port group (VPG) (a total of four). Each initiator, therefore, discovers four times the number of FC targets. HP recommends that you use iSNS to present to the initiator only the required iSCSI targets.
Use of iSCSI ports
When configuring the MPX200 for iSCSI, there are four available iSCSI ports per blade. For high performance and maximum initiator connectivity, HP recommends that you use all available ports.
Balancing the load
HP recommends that you use all iSCSI ports for both 1-GbE and 10-GbE blades. If multiple 1-GbE initiators are required, ensure that logins are spread across all 1-GbE ports. For 10-GbE blades, you can place a higher number of initiators on the 10-GbE ports than on the 1-GbE ports.
MPX200 Multifunction Router User Guide 25
Page 26
Because iSCSI and data migration traffic can share the same FC ports, it is prudent to understand how each function effects the other during I/O operation. The use of bandwidth throttling for data migration or MPIO for iSCSI provides a mechanism to allocate FC bandwidth to each function.
10-GbE initiators
HP recommends that you map servers with 10-GbE NICs for login to the 10-GbE ports on the MPX200.
CHAP security
You can configure the Challenge Handshake Authentication Protocol (CHAP) on the MPX200. CHAP is a security protocol that supports the bidirectional (mutual) authentication option and the one-way (target) authentication option. The target MPX200 can have a unique password for the one-way CHAP option. The initiator can have a unique password for the bidirectional CHAP option with the target MPX200. See the CHAP information in Chapter 5.

2 Installing the MPX200
This chapter describes how to rack mount the MPX200.
WARNING!
Mount the MPX200 in the rack so that the weight is evenly distributed. An unevenly loaded rack
can become unstable, possibly resulting in equipment damage or personal injury.
This product is supplied with a 3 wire cable and plug for the user's safety. Use this power cable
in conjunction with a properly grounded outlet to avoid electrical shock. An electrical outlet that is not correctly wired could place hazardous voltage on metal parts of the switch chassis. It is the responsibility of the customer to ensure the outlet is correctly wired and grounded to prevent electrical shock.
If the chassis is installed in a closed or multi-rack assembly, the operating temperature of the rack
environment may be greater than the ambient temperature. Be sure to install the chassis in an environment that is compatible with the maximum ambient rated temperature.

By default, the management port obtains a Dynamic Host Configuration Protocol (DHCP) address. If the management port cannot obtain a DHCP address, you must set a static IP address.
Fibre Channel zoning
Because the MPX200 can be a fabric-connected device, it is important to understand the zoning requirements.
Open zoning
When using an open zone configuration, each FC port on each MPX200 must be connected to a separate fabric (see Figure 18 on page 36).
MPX200 Multifunction Router User Guide 35
Page 36
Figure 18 Open zone configuration
.
Fibre Channel switch-based zoning
Each FC port on the MPX200 uses N_Port ID Virtualization (NPIV) to create a total of four unique, virtual world wide node names (WWNNs) per physical FC port. To create proper zoning, you must understand the use of VPGs. A VPG consists of a WWNN from each of the four physical FC ports. This allows presentation for up to 1,024 LUNs from a single EVA or XP array.
Place an array target port in the same zone as one of the VPG ports (see Figure 19 on page 37). This ensures a single path to the FC port on the router blade and gives you more control of load balancing through the router.

.
HP Command View EVA discovery
Once the management port IP address is set and the router FC ports are visible to the EVA, you can perform the MPX200 discovery. You discover the MPX200 iSCSI controllers using the Discover iSCSI
Devices button or the Add iSCSI Device button (see Figure 20).
Figure 20 iSCSI devices folder properties
.
MPX200 Multifunction Router User Guide 37
Page 38
NOTE:
HP recommends that you set a static IP address on the management port to ensure connectivity.
After the discovery is complete, the MPX200s appear in the iSCSI Devices folder as iSCSI Controller 01 and iSCSI Controller 02. The four iSCSI MPX200 hosts appear in the Hosts folder (see Figure 21). The ports associated with each host consist of the VPGs from each blade.

Page 43
Restore function allows you to restore the configuration to the point when the configuration was last saved, which is especially important for single-blade configurations.
NOTE:
A Restore action reboots the blade.
In a dual-blade configuration, a copy of the configuration for each router is kept on the peer. If you add a new blade, the configuration of the peer blade is copied to the new blade and is ready for use immediately; no reconfiguration is required.
To save or restore the MPX200 configuration:

5 MPX200 iSCSI configuration rules and guidelines
This chapter describes the iSCSI configuration rules and guidelines for the MPX200.
iSCSI rules and supported maximums
The MPX200 chassis can be configured with one or two blades. Dual-blade configurations provide for high availability with failover between blades, and are supported as redundant pairs only. iSCSI-connected servers can be configured for access to one or both blades.
NOTE:
In the event of a failover between blades, servers with single-blade connectivity to a failed blade will no longer have connectivity to the MPX200.
Table 4 lists the supported maximums.

The MPX200 is supported with the following EVA storage systems:
EVA4400/4400 with embedded switch
EVA4000/4100/6000/6100/8000/8100
EVA6400/8400
All MPX200 configurations must follow these EVA connectivity rules:
All MPX200 Fibre Channel connections are supported for fabric–connect or direct-connect config-
urations.
Each EVA storage system can connect to a maximum of one MPX200 chassis (two blades).
Each EVA controller host port can connect to a maximum of two MPX200 Fibre Channel ports.
A maximum of one MPX200 chassis (two blades) can be zoned with up to four EVA storage systems.
An EVA storage system can present LUNs to iSCSI initiators and Fibre Channel hosts concurrently.
HP Command View EVA management rules and guidelines
The HP Command View EVA implementation for the MPX200 supports management of up to four EVA storage systems concurrently, and provides the equivalent functionality for both iSCSI and Fibre Channel connected servers. All MPX200 management functions are integrated in HP Command View EVA.
IMPORTANT:
The MPX200 requires a specific controlled release of HP Command View EVA. For more information and to receive the supported HP Command View EVA version, contact your HP service representative.
MPX200 iSCSI configuration rules and guidelines54
Page 55
The HP Command View EVA management rules and guidelines follow:
Requires HP Command View EVA 9.1.1 or later for array-based and server-based management.
A maximum of one MPX200 chassis (two blades) can be discovered by an EVA storage system.
HP Command View EVA manages the MPX200 out of band (IP) through the MPX200 management
IP port. The HP Command View EVA application server must be on the same IP network as the MPX200 management IP port.
The MPX200 iSCSI initiator and iSCSI LUN masking information resides in the MPX200, not in
the HP Command View EVA database.
The default iSCSI initiator EVA host-mode setting is Microsoft Windows. The iSCSI initiator host-
mode setting for Apple Mac OS X, Linux, Oracle Solaris, VMware, and Windows 2008 is con­figured with HP Command View EVA.
NOTE:
Communication between HP Command View EVA and the MPX200 is not secured by the communication protocol. If unsecured communication is a concern, HP recommends using a confined or secured IP network in the data center.
EVA storage system software
EVA storage system software supported for Fibre Channel hosts, such as HP StorageWorks Continuous Access, Business Copy, Storage System Scripting Utility (SSSU), and Replication Solutions Manager (RSM), are supported with the MPX200 for EVA LUNs that have been presented to iSCSI initiators. This section describes restrictions for iSCSI hosts using the MPX200.
Features supported for iSCSI hosts
The following Business Copy features are supported for iSCSI hosts:
LUN snapshots presented to iSCSI hosts
LUN snapclones (normal or 3-phase) presented to iSCSI hosts
Instant restore from a snapclone to the original source
Ability of iSCSI hosts to access and write to EVA snapshots and snapclones
Use of HP Command View EVA, SSSU, or RSM to create snapshots manually or automatically on
a schedule
CLI support to enter replication commands from iSCSI hosts
Features not supported for iSCSI hosts
LUNs that are presented to iSCSI hosts through the MPX200, and that require a host agent on the iSCSI initiator, do not support advanced replication features because there are no iSCSI replication host agents available. The following features are not supported for iSCSI hosts:
Mounting and unmounting LUNs through a host agent, which must be performed manually
Accessing the host view of storage (for example, viewing an F drive from a host)
Deploying host agents to allow users to launch a script on the iSCSI host

Multipathing
Microsoft MPIO includes support for redundant paths to send I/O from the initiator to the target. For Windows Server 2008, MPIO is a separate feature that must be installed separately. Microsoft iSCSI Software Initiator 2.x includes MPIO and must be selected for installation. Setting up redundant paths properly ensures high availability of the target disk. Ideally, the paths would use separate network interface cards (NICs) and a separate network infrastructure (cables, switches, and MPX200 blades). HP recommends using separate target ports.
Microsoft MPIO allows the initiator to log in to multiple sessions to the same target and aggregate the duplicate devices into a single device exposed to Windows. Each session to the target can be established using different NICs, network infrastructure, and target ports. If one session fails, another session can continue processing I/O without interrupting the application. The iSCSI target must support multiple sessions to the same target. The Microsoft iSCSI MPIO DSM supports a set of load-balance policies that determine how I/O is allocated among sessions. With Microsoft MPIO, the load-balance policies apply to each LUN individually.
The Microsoft iSCSI DSM 2.x assumes that all targets are active/active and can handle I/O on any path at any time. There is no mechanism in the iSCSI protocol to determine whether a target is active/active or active/passive; therefore, the MPX200 supports only multipath configurations with the EVA with active/active support.

Installing and configuring the iSCSI driver for Red Hat 5
NOTE:
The iSCSI driver package is included but is not installed by default. Install the package iscsi—initiator—utils during or after operating system installation.
To install and configure the iSCSI driver for Red Hat 5:
1. Use the iscsiadm command to control discovery and connectivity:
# iscsiadm –m discovery –t st –p 10.6.0.33:3260
2. Edit the initiator name:
# vi /etc/iscsi/initiatorname.iscsi
3. Start the iSCSI service:
# service iscsi start
MPX200 iSCSI configuration rules and guidelines78
Page 79
4. Verify that the iSCSI service starts automatically:
#chkconfig iscsi on
NOTE:
For details, see the man pages for the iscsiadm open-iscsi administration utility.
Installing and configuring the iSCSI driver for Red Hat 4 and SUSE 9
NOTE:
The iSCSI driver is included with the Red Hat 4 and SUSE 9 distributions and is installed by default. Configuration is the same for Red Hat 3 and 4 and SUSE 8 and 9.
To install and configure the iSCSI driver for Red Hat 4 and SUSE 9:
1. Update the /etc/iscsi.conf file to include the IP address of the iSCSI target.
The configuration file might include entries like this: DiscoveryAddress=33.33.33.101 For a detailed description of the configuration file format, enter the following command:
man iscsi.conf
2. Manually start iSCSI services to test your configuration:
/etc/init.d/iscsi start
3. Modify the /etc/<initiatorname>.iscsi file to assign a meaningful name to the initiator.
For example:
InitiatorName=iqn.1987–05.com.cisco:servername.yourcompany.com
NOTE:
In most cases, you only modify the text following the colon.
If there is a problem starting the iscsi daemon, it is usually due to an incorrect IP address or an incorrectly formatted initiator name.
Installing the iSCSI initiator for Red Hat 3 and SUSE 8
If you are upgrading from a previous version of an iSCSI driver, HP recommends that you remove the /etc/<initiatorname>.iscsi file before installing the new driver. For the latest version of the Linux driver for EVA iSCSI connectivity, see:
http://sourceforge.net/projects/linux-iscsi
MPX200 Multifunction Router User Guide 79
Page 80
NOTE:
The Linux driver supports both Red Hat 3 and SUSE 8. For information on how to configure the Linux iSCSI initiator, see the
Assigning device names
Linux assigns SCSI device nodes dynamically when it detects a SCSI logical unit; therefore, the mapping from device nodes (such as /dev/sda and /dev/sdb) to iSCSI targets and logical units may vary.
Variations in process scheduling and network delay can result in iSCSI targets being mapped to different SCSI device nodes each time the driver is started. Therefore, configuring applications or operating system utilities to use the standard SCSI device nodes to access iSCSI devices can result in SCSI commands being sent to the wrong target or logical unit.
To ensure consistent naming, the iSCSI driver scans the system to determine the mapping from SCSI device nodes to iSCSI targets. The iSCSI driver creates a tree of directories and symbolic links under /dev/iscsi to facilitate access to a logical unit of an iSCSI target.
The directory tree under /dev/iscsi contains subdirectories for each iSCSI bus number, each target ID number on the bus, and each LUN for each target. For example, the disk device for bus 0, target ID 0, and LUN 0 would be /dev/iscsi/bus0/target0/LUN0/disk.
Each logical unit directory contains a symbolic link for each SCSI device node that can connect to that logical unit. The symbolic links are named using the Linux devfs naming convention.
Readme
file in the tar ball.
The symbolic link disk maps to the whole-disk SCSI device node (for example, /dev/sda or /
dev/sdb).
The symbolic links, part1 through part15, map to each partition of the SCSI disk. For example,
a symbolic link can map to partitions /dev/sda1 and dev/sda15, or to as many partitions as necessary.
NOTE:
The symbolic links exist regardless of the number of disk partitions. Accessing a partition name results in an error if the partition does not exist on the disk.
The symbolic link mt maps to the auto-rewind SCSI tape device node for the LUN (for example,
/dev/st0). Additional links for mtl, mtm, and mta map to the other auto-rewind devices (for
example,/dev/st0l, /dev/st0m, /dev/st0a), regardless of whether those device nodes exist or can be opened.
The symbolic link mtn maps to the no-rewind SCSI tape device node, if any. (For example, this
LUN maps to /dev/nst0.) Additional links (formtln, mtmn, and mtan) map to the other no­rewind devices (for example, /dev/nst0l, /dev/nst0m, /dev/nst0a), regardless of whether those device nodes exist or can be opened.
The symbolic link cd maps to the SCSI CD-ROM device node, if any, for the LUN (for example,
/dev/scd0).
The symbolic link generic maps to the SCSI generic device node, if any, for the LUN (for example,
/dev/sg0).
MPX200 iSCSI configuration rules and guidelines80
Page 81
The symlink creation process must open all SCSI device nodes in /dev to determine which nodes map to iSCSI devices. Therefore, several modprobe messages may be logged to syslog indicating that modprobe could not find a driver for a particular combination of major and minor numbers. You can ignore these messages, which occur when Linux is unable to find a driver to associate with a SCSI device node that the iSCSI daemon is opening as part of the symlink creation process. To prevent these messages from occurring, remove the SCSI device nodes that do not contain an associated high-level SCSI driver.
Target bindings
The iSCSI driver automatically maintains a bindings file, /var/iscsi/bindings. This file contains persistent bindings to ensure that the same iSCSI bus and target ID number are used for every iSCSI session with a particular iSCSI TargetName, even if the driver is restarted repeatedly.
The bindings file ensures that the SCSI number in the symlinks device (described in Device
names” on page 80) always maps to the same iSCSI target.
NOTE:
Linux dynamically allocates SCSI device nodes as SCSI devices are found; therefore, the driver cannot ensure that a SCSI device node (for example, /dev/sda) always maps to the same iSCSI target name. The symlinks described in Device names” on page 80 provide application and fstab file persistent device mapping; use these symlinks instead of direct references to SCSI device nodes.
If the bindings file grows too large, you can edit the file and remove the lines for targets that no longer exist. This should not be necessary because the driver can maintain up to 65,535 bindings.
Mounting file systems
The Linux boot process typically mounts the file systems listed in /etc/fstab before the network is configured; therefore, adding mount entries in iSCSI devices to /etc/fstab does not work. The
iscsi-mountall script manages the checking and mounting of devices listed in /etc/ fstab.iscsi, which has the same format as /etc/fstab. This script is invoked automatically by
the iSCSI startup script.
NOTE:
If iSCSI sessions are unable to log in immediately due to network or authentication problems, the iscsi-mountall script may time out and fail to mount the file systems.
Mapping inconsistencies can occur between SCSI device nodes and iSCSI targets (for example, the wrong device is mounted because of device name changes resulting from iSCSI target configuration changes or network delays). Instead of directly mounting SCSI devices, HP recommends that you do one of the following:
Mount the /dev/iscsi symlink tree.
Mount the file system UUIDs or labels (see the man pages for mke2fs, mount, and fstab).
Use the Logical Volume Manager (see Linux LVM).
MPX200 Multifunction Router User Guide 81
Page 82
Unmounting file systems
You must unmount all file systems on iSCSI devices before the iSCSI driver stops. If the iSCSI driver stops while iSCSI devices are mounted, buffered writes may not be committed to disk, and file system corruption may occur.
Linux does not unmount file systems that are being used by a process; therefore, any process using those devices must be stopped (see the man page for fuser(1)) before iSCSI devices can be unmounted.
To prevent file system corruption, the iSCSI shutdown script automatically stops all processes using devices in /etc/fstab.iscsi. The script sends a SIGTERM signal to stop the processes, followed by a SIGKILL signal to stop any remaining processes. It then unmounts all iSCSI file systems and stops the iSCSI daemon, terminating all connections to iSCSI devices.
CAUTION:
File systems not listed in /etc/fstab.iscsi cannot be unmounted automatically.

MPxIO overview
The Sun multipathing software (MPxIO) provides basic failover and load-balancing capability to HP StorageWorks EVA4x00/6x00/8x00 storage arrays. MPxIO allows the merging of multiple SCSI layer paths, such as an iSCSI device exposing the same LUN through several different iSCSI target names. Because MPxIO is independent of transport, it can multipath a target that is visible on both iSCSI and FC ports. This section describes only the iSCSI implementation of MPxIO with the MPX200.
For more information about MPxIO, see the Solaris Fibre Channel and Storage Multipathing Administration Guide, available at http://docs.sun.com/source/819-0139.
Preparing the host system
To verify that MPxIO is enabled:
1. Enter the following command:
cat kernel/drv/iscsi.conf
2. Verify the MPxIO setting:
mpxio-disable=”no” If the setting is yes, change it to no, and then reboot:
Reboot -- -r
Example: MPxIO on all iSCSI port settings in /kernel/dev/iscsi.conf

HP storage arrays are supported with MPxIO:
As symmetric devices only
MPX200 iSCSI configuration rules and guidelines88
Page 89
With no load balancing
With no failback
To configure MPxIO for HP storage arrays, you must add information to the /kernel/drv/ scsi_vhci.conf file:
1. Use a text editor to modify the configuration file. For example:
# vi /kernel/drv/scsi_vhci.conf
2. Change load balancing to none:
load-balance="none";
3. Change auto-failback to disable:
auto-failback="disable";
MPX200 Multifunction Router User Guide 89
Page 90
4. Add the following lines for the EVA4x00/6x00/8x00 storage arrays:
device-type-scsi-options-list =
“HP HSV“, “symmetric-option“;
symmetric-option = 0x1000000;
NOTE:
You must enter six spaces between HP and HSV.
Example: HP storage array settings in /kernel/drv/scsi_vhci.conf
# # Copyright 2004 Sun Microsystems, Inc. All rights reserved. # Use is subject to license terms. # #pragma ident "@(#)scsi_vhci.conf 1.9 04/08/26 SMI" # name="scsi_vhci" class="root"; # # Load balancing global configuration: setting load-balance="none" will cause # all I/O to a given device (which supports multipath I/O) to occur via one # path. Setting load-balance="round-robin" will cause each path to the device # to be used in turn. #
load-balance="none";
# # Automatic failback configuration # possible values are auto-failback="enable" or auto-failback="disable"
auto-failback="disable";
# # For enabling MPxIO support for 3rd party symmetric device need an # entry similar to following in this file. Just replace the "SUN SENA" # part with the Vendor ID/Product ID for the device, exactly as reported by # Inquiry cmd. # # device-type-scsi-options-list = # "SUN SENA", "symmetric-option"; # # symmetric-option = 0x1000000; #
device-type-scsi-options-list = "HP HSV","symmetric-option"; symmetric-option = 0x1000000;
5. Reboot to activate the changes:
# reboot -- -r
Editing the sgen.conf file
To ensure that the HP storage arrays are recognized by Solaris as SCSI controllers, you must add information to the /kernel/drv/sgen.conf file:
1. Use a text editor to modify the configuration file. For example:
# vi /kernel/drv/sgen.conf
MPX200 iSCSI configuration rules and guidelines90
Page 91
2. Add array_ctrl to device-type-config-list:
device-type-config-list="array_ctrl";
3. Uncomment all target/LUN pair entries.
Example: HP storage array settings in /kernel/drv/sgen.conf
. . . # devices on your system. Please refer to sgen(7d) for details.
# # sgen may be configured to bind to SCSI devices exporting a particular device # type, using the device-type-config-list, which is a ',' delimited list of # strings.
# device-type-config-list="array_ctrl";
. . . # After configuring the device-type-config-list and/or the inquiry-config-list, # the administrator must uncomment those target/lun pairs at which there are # devices for sgen to control. If it is expected that devices controlled by # sgen will be hotplugged or added into the system later, it is recommended # that all of the following lines be uncommented.
name="sgen" class="scsi" target=0 lun=0; name="sgen" class="scsi" target=1 lun=0; name="sgen" class="scsi" target=2 lun=0; name="sgen" class="scsi" target=3 lun=0; name="sgen" class="scsi" target=4 lun=0; name="sgen" class="scsi" target=5 lun=0; name="sgen" class="scsi" target=6 lun=0; name="sgen" class="scsi" target=7 lun=0; name="sgen" class="scsi" target=8 lun=0; name="sgen" class="scsi" target=9 lun=0; name="sgen" class="scsi" target=10 lun=0; name="sgen" class="scsi" target=11 lun=0; name="sgen" class="scsi" target=12 lun=0; name="sgen" class="scsi" target=13 lun=0; name="sgen" class="scsi" target=14 lun=0; name="sgen" class="scsi" target=15 lun=0;
Creating an sgen driver alias
The HP storage array is a self-identifying SCSI device and must be bound to the sgen driver using an alias. Execute the following procedure to create an sgen driver alias:
MPX200 Multifunction Router User Guide 91
Page 92
1. Update the sgen driver:
# update_drv –a –I “scsiclass,0c” sgen
NOTE:
Lowercase c is mandatory.
2. Verify the sgen alias setting:
#egrep sgen /etc/driver_aliases
Example:
# rep sgen /etc/driver_aliases sgen "scsa,08.bfcp" sgen "scsa,08.bvhci"
sgen "scsiclass,0c"
Enable iSCSI target discovery
Solaris supports three iSCSI target discovery methods:
SendTargets
Static
iSNS
This section describes SendTargets discovery only. For information on static and iSNS discovery, see
http://docs.sun.com/app/docs/doc/817-5093/fqnlk?l=en&=view.
To enable iSCSI target discovery:
1. Enter the following command:
# iscsiadm modify discovery –t enable
2. Verify that SendTargets is enabled:
# iscsiadm list discovery
3. The MPX200 has multiple iSCSI ports available to the Solaris iSCSI initiator. To discover the
targets available, enter the following command for each iSCSI port IP address that the iSCSI initiator accesses:
#iscsiadm add discovery-address ‘iscsi port IP address’
4. Verify the discovery address entries:
#iscsiadm list discovery-address
MPX200 iSCSI configuration rules and guidelines92
Page 93
5. After discovery addresses are entered, the Solaris iSCSI initiator polls each address for all targets
available. To list the targets available to the initiator, enter the following command:
#iscsiadm list target
Example:
#iscsiadm list target Target: iqn.1986-03.com.hp:fcgw.mpx200.0834e00028.b2.01.50014380025c4179
Alias: ­TPGT: 0 ISID: 4000002a0000 Connections: 1
Target: iqn.1986-03.com.hp:fcgw.mpx200.0834e00028.b1.01.50014380025c417d
Alias: ­TPGT: 0 ISID: 4000002a0000 Connections: 1
NOTE:
The iSCSI initiator must discover all targets presented by each MPX200 iSCSI port that will be used in a multipath configuration.
6. Create the iSCSI device links for the local system:
# devfsadm -i iscsi
Modifying the target parameter MaxRecvDataSegLen
Sun recommends that you set the MaxRecvDataSegLen parameter to 65,536 bytes for each iSCSI discovered target. For more information, see http://wikis.sun.com/display/StorageDev/
iSCSI+Features+Related+to+RFC+3720+Parameters.
To modify the target parameter MaxRecvDataSegLen:
1. List all iSCSI targets:
#iscsiadm list target-param
2. Change the value of MaxRecvDataSegLen to 65536 for each target:
#iscsiadm modify target-param -p maxrecvdataseglen=65536 ‘target iqn’
MPX200 Multifunction Router User Guide 93
Page 94
3. Use the following example to verify the target setting:

iscsiadm list target -S
This command lists targets with their presented LUNs. In a multipath environment, the same LUN should appear under different EVA port targets from the same controller.
Example:
iscsiadm list target -S Target: iqn.1986-03.com.hp:fcgw.mpx200.0834e00028.b2.01.50014380025c4179

Configuring Microsoft MPIO iSCSI devices
For Microsoft MPIO, the load-balance policies apply to each LUN individually. To display and modify the LUN load-balance policy (Figure 68):
1. Start the Microsoft iSCSI Control Panel applet.
2. Select the Target tab.
3. Click Details.
4. Click Devices.
5. Highlight a LUN device name, and then click Advanced.
6. Select the MPIO check box.

Microsoft MPIO for iSCSI load-balancing policies
The Microsoft MPIO for iSCSI load-balancing policies are as follows:
Failover Only. No load balancing is performed. There is a single active path; the remaining paths
are standby paths. The active path sends all I/O. If the active path fails, a standby path is used. When the formerly active path is reconnected, it becomes active and the activated standby path returns to standby.
Round-robin. All paths are active paths and are used to send I/O in a round-robin fashion.
Round-robin with a subset of paths. One set of paths is configured as active and another set of
paths is configured as standby. I/O is sent in a round-robin fashion over the active paths. If all active paths fail, a standby path is used. When a formerly active path is reconnected, it becomes active and the activated standby path returns to standby.
Weighted Path. Each path is assigned a weight and I/O is sent on the path with the lowest weight.
If the path with the lowest weight fails, the path with the next lowest weight is used.
Least Queue Depth. This is not supported by MPIO.
NOTE:
For raw disk access, the MPIO load-balancing policy must be Failover Only. For file system disk access, all MPIO load-balancing policies are supported. Failover policies are set on a LUN-by-LUN basis. MPIO does not support global failover settings.

Microsoft MPIO with QLogic iSCSI HBA
The QLogic iSCSI HBA is supported in a multipath Windows configuration that is used in conjunction with Microsoft iSCSI initiator services and Microsoft MPIO. Because the iSCSI driver resides on the QLogic iSCSI HBA, it is not necessary to install the Microsoft iSCSI initiator.
Installing the QLogic iSCSI HBA
Install the QLogic iSCSI HBA hardware and software following the instructions in the QLogic installation manual. The QLogic iSCSI HBA is managed by the QLogic SANsurfer Management Suite (SMS).
NOTE:
After installing the QLogic iSCSI HBA, you must configure the QLogic iSCSI initiator through SMS. The QLogic iSCSI HBA does not appear in the Microsoft Network Connection device list.
Installing the Microsoft iSCSI initiator services and MPIO
To install the Microsoft iSCSI initiator:
1. Access the Microsoft iSCSI Initiator Installation page of the Software Update Installation Wizard
(Figure 69).
Figure 69 Microsoft iSCSI Initiator Installation page
.
IMPORTANT:
Do not select the Software Initiator check box. The QLogic initiator resides on the iSCSI HBA.
2. Reboot the system.
MPX200 iSCSI configuration rules and guidelines98

Configuring the QLogic iSCSI HBA
To configure the QLogic iSCSI HBA:
1. Launch the QLogic SMS from the desktop icon or through Start > Programs, and connect to the
local host (Figure 70).
MPX200 Multifunction Router User Guide 99
Page 100
2. Click Yes to launch the general configuration wizard (Figure 71). Use the wizard to:
Select iSCSI HBA port to configure the QLogic iSCSI HBA.
Configure the HBA Port network settings.
Configure the HBA Port DNS settings (optional).
Configure the SLP Target Discovery settings (optional).
Configure the iSNS Target Discovery settings (optional).
