The router is equipped with three fans in a single module.

Figure 4: Fan module

25Network Storage Router M2402 User Guide

Introduction

If one of the three fans fails, the router will continue to operate on the two remaining fans until a replacement fan module can be installed.

If the fan is not cooling the router properly, a temperature warning message is displayed in the Home Page of the Web-based user interface.

Fan module functionality can be verif ied from both the Serial/Telnet user interface and the Web-based user interface.

Note: The Web-based user interface is also called Visual Manager. Visual Manager is

discussed in Chapter 4, The Serial/Telnet user interface is discussed in Chapter 5.

Fibre Channel Modules

Multiple Fibre Channel modules can be added to the router.

Functional Overview

The router translates the Fibre Channel Protocol (FCP) to and from the SCSI Protocol. It transfers commands, data, and status information to and from Fibre Channel (FC) controllers and SCSI devices.

Supported devices include:

■ Initiator Devices – FC and SCSI hosts

■ Direct Access Devices – RAID Controllers, Disk drives, JBODs

■ Sequential Access Devices – Tape drives

■ Changer Devices – Tape and Magneto-Optical Libraries

The router provides multiple FC to SCSI I/O configurations. A sample configuration is illustrated in Figure 9.

Item Process

A Fibre Channel host issues an encapsulated FCP protocol command packet to the router

The router Fibre Channel controller interprets the Fibre Channel information, and places the packet in buffer memory.

The router interprets the Fibre Channel information packet and programs the router SCSI controller to process the transaction.

The router SCSI controller sends the command to the SCSI device (target).

The SCSI target interprets the command and executes it.

SCSI Connections

The router supports Fast/Ultra-2 Narrow/Wide SCSI. The router is factory configured to support LVD/Single-Ended or HVD (Diff), or a mixture of both types of SCSI buses. Up to twelve SCSI buses can be attached, using 3 SCSI modules.

Note: The router must always be installed at the end of SCSI buses.

The router supplies termination power (TERMPWR) to each SCSI bus.

Note: During certain faults, the termination power IC will shut down. It may be

restarted once the fault is cleared.

Caution: During the attachment of high density SCSI cables, note the

orientation of the high-density SCSI port connectors. Connector orientation failure may result in connector damage.

Caution: LVD/SE and HVD connections must be made on appropriate I/O

modules. Failure to heed this caution may result in damage to equipment.

Caution: Failure to comply with the minimum high-density cable

specifications can result in damage to the router or an operational failure of the product.

48 Network Storage Router M2402 User Guide

Installation

Note: SCSI cables used with the router must meet SCSI 2 standards. Optional SCSI

cables are available from your supplier.

To connect the router to a SCSI device:

1. Power off the router and SCSI devices.

2. Locate the SCSI buses on the back of the router (see Figure 24).

Figure 24: SCSI buses

3. Connect a SCSI cable to one of the SCSI buses on the router.

Note: The router should always be installed at the end of the SCSI bus.

Note: SE is not supported by SCSI-3 protocols. While it is possible to mix SE and LVD

devices on the same bus, doing so will result in substantially decreased performance on the bus.

4. Connect the SCSI cable to the SCSI device.

5. Verify that the bus is terminated correctly. By default, the router is automatically terminated. However, the device at the other end of bus must also be terminated.

Configuration Overview

Router Default Settings

Some of the basic factory default values are:

■ IP address: http://1.1.1.1/

■ Subnet mask: 255.255.255.0

■ Gateway address: 0.0.0.0

■ User name: root

■ Password: password

HP recommends these values be changed from the defaults. All settings within the router configuration are pre-set with default values. These

values are set to allow the router to be installed into most HP environments with little or no configuration changes.

After changing the basic default values listed above, carefully consider any additional configuration changes.

After the initial configuration of the router is established, HP recommends backing up the configuration to an external file. If needed, during a recovery process, this file can then be restored back onto the router.

54 Network Storage Router M2402 User Guide

55Network Storage Router M2402 User Guide

Configuration Overview

Common Configuration Settings

To provide connectivity between hosts and devices, the router must establish an address on each connected FC network and SCSI bus. The following paragraphs discuss configuration settings that are commonly modified and are av ailable in the Visual Manager UI and the Serial/Telnet UI. For procedural information on accessing and changing these settings, see Chapter 4, “Visual Manager User Interface,” and Chapter 5, “Serial/Telnet User Interface.”

Controller LUN Commands

The router supports a set of SCSI-3 commands that can be received as FCP commands over the FC bus. These commands provide support for value added features such as Extended Copy. When using these commands, they must be sent to the Controller LUN. For more information, see Appendix B, “Controller LUN Commands.”

SCSI Bus Configuration

The router can appear on a SCSI bus as a pair of initiators. The primary Initiator ID can be set to any valid SCSI address (0-15) and is used for most traffic. The alternate Initiator ID can also be set to any valid SCSI address (0-15) and is for use with high priority traffic. The Initiator IDs (primary and alternate) should not be set to the same SCSI address and no other devices on the SCSI bus may use either of these SCSI addresses.

The router can also appear as one or more Target ID on a SCSI b us. By defau lt, no Target IDs are set up.

The router provides the capability to reset SCSI buses during the router boot cycle. This allows devices on a SCSI bus to be in a known state. The reset option can be enabled/disabled during configuration of the router. The SCSI bus reset feature is enabled in the default configuration but should be disabled for configurations using multiple initiators, tape changers or other devices that have long reset cycles, or for environments that are adversely affected by bus resets.

The router negotiates the maximum values for transfer rates and bandwidth on a SCSI bus. If an attached SCSI device does not allow the full rates, the router will use the best rates it can negotiate for that device. Because negotiation is on a device-specific basis, the router can support a mix of SCSI device types on the same SCSI bus.

56 Network Storage Router M2402 User Guide

Fibre Channel Port Configuration

By default, the configuration of the FC ports is set to N_Port, which minimizes conflicts when both the router and another FC device, such as a switch, are using Auto Sensing for FC ports. Alternatively, the configuration of the FC ports can be set to Auto Sensing, which allows the router to detect whether it is connected to an Arbitrated Loop or a Switched Fabric.

Note: By default, the Fibre Channel port speed is set to 1 Gb/s. Changes to the Fibre

Channel port speed must be manually set, such as for 2 Gb/s. If set incorrectly and the router is plugged into a Loop or Fabric, the unit may receive framing errors because of the incorrect Fibre Channel link speed.

Fibre Channel Arbitrated Loop Configuration

On a Fibre Channel Arbitrated Loop, each device appears as an Arbitrated Loop Physical Address (AL_PA). To obtain an AL_PA, two methods can be used:

■ Soft addressing

■ Hard addressing

Configuration Overview

Soft addressing is the default setting.

Soft Addressing

During soft addressing, the router automatically acquires the first available loop address, starting from 01 and moving up to EF. The router may participate on the FC loop, as long as there is at least one address avail able o n the loop connected to the router. FC supports up to 126 devices on an Arbitrated Loop.

Hard Addressing

During hard addressing, the router attempts to acquire the AL_PA value specified in the configuration settings. If the desired address is not available at loop initialization time, the router negotiates the next available soft address. This allows both the loop and the router to continue to operate.

57Network Storage Router M2402 User Guide

Configuration Overview

Hard addressing is recommended for FC Arbitrated Loop environments where it is important that the FC device addresses do not change. Device address changes can affect the mapping represented by the host operating system to the application, and have adverse effects. An example is tape library installation, where the application configuration requires fixe d de v ice identif ication for prop er operation.

Fibre Channel Switched Fabric Configuration

When connected to a FC switch, the router is identified to the switch as a unique device by the factory programmed World Wide Name (WWN).

Discovery Mode

This feature makes it easy to discover attached FC and SCSI target devices and automatically map them on the host side for the bus/port in question.

There are two discovery methods available:

■ Manual discovery

■ Auto discovery

Auto Discovery can be set to occur after reboot events (when the router reboots) or link-up events (for instance, when cables are attached or a hub is rebooted). Auto Discovery can be disabled by setting the router to Manual Discovery.

Host Device Configuration

A host system using a FC Host Bus Adapter (HBA) will typically map devices into the existing device-mapping scheme used by that operating system. Refer to the HBA manual for the mapping table.

Mapping involves pairing FC_AL_PA to SCSI target address. The HBA will claim enough SCSI bus entries to allow up to 125 FC targets to be mapped to SCSI Bus:Target entries. This is usually done by a fixed mapping of AL_PA to Bus:Target. In such a configuration, the router corresponds to a Bus:Target identifier, with the attached SCSI devices appearing as logical units (LUNs). Operating systems can extend the available SCSI limit of 15 targets per bus. Although this is not an issue for the operating system or most applications, there are cases where older applications can have expectations about what constitutes a valid SCSI ID, and thus may not correctly handle certain mappings. In particular, some applications may exhibit difficulties addressing target IDs greater than 15

58 Network Storage Router M2402 User Guide

(16 and up, for example). This situation can be resolved by configuring the router to use hard addressing and setting the AL_PA to a value less then 16 that the HB A will be able to map.

For example, depending on the FC HBA, if the hard AL_PA selection is 1, then the address is 1. If the selection is 125, the AL_PA address is 0xEF. Some FC HBAs will map devices differently, so verify the AL_PA by reviewing the documentation for the HBA.

Logical Unit Management

Because SAN resources can be shared, it is possible for multiple hosts to have access to the same devices on the SAN. To prevent conflicts, the router provides LUN management as a means to restrict device access to certain hosts. LUN management goes beyond simple LUN masking, to prevent gaps in the list of LUNs presented to a host.

LUN management maps can be created for different views of the devices attached to the router. E ach FC host is assigned a specific map conf iguration. Not only can the administrator control which devices a host may access, but also which LUNs are used to access these devices.

For a FC host, a map is a table of LUNs, where each entry is either empty or contains device address information needed for host/device comm un ic ation.

For a SCSI host, a map contains a list of target IDs, each of which has its own table of LUNs with address information needed for host/device communication.

Configuration Overview

Note: The router can respond to multiple Target IDs on a SCSI bus.

Both FC ports and SCSI buses have user-defined maps and pre-defined maps. There are three predefined maps:

■ Indexed (default)

■ Auto Assigned

■ SCC

When a host sends a command, the router will select which map to use, based on the port receiving the command and the ID of the host sending the comman d. For FC ports, the host ID is the World Wide Name and for SCSI buses, the host ID is the Initiator ID (0 - 15). When a host is unknown or is not assigned a specif ic map, the router will use the default map.

59Network Storage Router M2402 User Guide

Configuration Overview

Indexed Maps

An Indexed map is initially empty and can be modified by the user.

Auto Assigned Maps

An Auto Assigned map is built dynamically and contains all of the devices found during discovery. This map will change automatically any time the discovery process finds a change in the devices attached. This map cannot be modified by the user.

SCC Maps

An SCC map is only available on FC ports and contains only a single entry for LUN 0. This LUN is a router controller LUN. Access to attached devices is managed using SCC logical unit addressing.

Buffered Tape Writes

This option is designed to enhance system performance by returning status on consecutive write commands prior to the tape device receiving data. In the event that data does not transfer correctly, the router will return a check condition on a subsequent command.

Commands other than Write are not issued until status is received for any pending write, and status is not returned until the device completes the command. This sequence is appropriate for tasks such as file backup or restore.

Some applications require confirmation of individual blocks being written to the medium, such as for audit trail tapes or log tapes. In these instances, the Buffered Tape Writes option must be disabled.

Visual Manager Best Practices

The following recommendations should be observed:

■ A standard keyboard and mouse must be used to navigate in the VM.

■ The router is shipped with a configuration of default settings that is acceptable

for most system environments. Few changes to the configuration should be necessary.

■ After any configuration changes are made, depending on the menu option,

select Submit or Configure to send changes from the Web browser to the router.

■ Changes will take effect during the next router reboot cycle.

■ If the configuration has been modified to meet company-specific needs, back

up the company-specific configuration to an external file. If necessary, these settings can later be restored to the router.

■ Fields are not case-sensitive, except for the user name and password.

■ HP recommends that you not bookmark VM pages with the Web browser.

■ Because configuration information is transmitted via URLs, it is possible that

the router could be configured with information present at the time a page was bookmarked.

■ HP recommends navigating only using the Web page links contained in VM

itself.

Visual Manager User Interface

■ Depending on the Web browser used, these links will often appear as

highlighted text. By selecting these links, VM can be safely navigated.

Ethernet Configuration Settings

Ethernet configuration settings:

■ Host name is an alphanumeric entry of one word up to 8 characters in length.

■ Ethernet Mode can be set to one of the following options:

—10Mps Only — 100Mps (half duplex) Only — 100Mps (full duplex) Only — 10/100Mps (Auto-Neg.)

■ IP address (default: 1.1.1.1) is the IP address of the router.

■ Subnet Mask (default: 255.255.255.0) is the IP subnet mask for the router.

■ IP Gateway (default: 0.0.0.0) is the IP address of the gateway for the Ethernet

network connected to the router.

■ DHCP enables or disables support for Dynamic Host Configuration Protocol.

When DHCP is enabled, the router will request a dynamic IP address from a DHCP server on the Ethernet network. The router must be rebooted before an IP address will be requested from the DHCP server. After the router is rebooted, the HTTP session will have to be restarted. The IP address will be different from the former non-DHCP IP address.

Note: To use the DHCP feature, a DHCP server must be operational on the Ethernet

network. If the DHCP feature is used when there is not DHCP server, the standard for DHCP requires the router wait thee minutes for a response from a DHCP server before timing out.

Some DHCP servers allow a lease reserv ation to be set up for an IP address b y providing the server with the Ethernet MAC address. The DHCP server will then always provide the same IP address to the router. This setup can be useful for remote management of the router via Telnet or VM. Because the method of setting up a lease reservation varies, depending on the DHCP server being used contact the Network Administrator for assistance.

Note: Auto-Assigned and SCC maps cannot be modified, cleared, filled, or have

entries deleted.

Note: Map settings are saved to memory when any button within the page is selected.

SCSI Map settings:

■ Clear Map clears all entries from the current map.

■ Fill Map fills in the current map.

When the map is filled, the display will show the current devices.

■ Remove Gaps removes any incremental gaps in the sequence of LUN listed

in the table. When the system removes gaps from the table, the LUN are renumbered in

sequential order, starting with LUN 0.

Note: Some operating systems require gaps be removed in the mapping table to

detect all devices.

■ Delete deletes map entries.

To delete a range of LUNs, select the beginning LUN to delete from the ‘from’ drop-down box and select the last LUN to delete from the ‘to’ drop-down box.

■ Discovered Device Entry adds a discovered device to the map.

To add a discovered device to the map, use the drop-down boxes to enter the settings, and then click Create Entry in the Discovered Dev ice Ent r y sectio n of the screen.
