Power Supply

The SR2122-2 has an internal power supply that monitors its temperature and output voltages. The power supply automatically senses and adjusts to either of these input voltages: 115 VAC/60 Hz or 230 VAC/50 Hz.

If conditions reach critical thresholds, the power supply shuts down to avoid damage from excessive heat or electrical current. The power supply connects to site power through a power cord and the power connector on the rear panel. The power supply is powered on with a rocker switch next to the power connector. The switch is labeled off.

Installation

Site Planning

Planning the proper location and layout of your SR2122-2, your equipment rack, or wiring closet is essential for successful storage router operation. Equipment placed too close together or in a poorly ventilated area can cause the system to overheat. In addition, poor equipment placement can make system panels inaccessible and difficult to maintain.

Table 20 in Appendix A lists the operating and nonoperating environmental site

requirements for the SR2122-2. Within specified environmental ranges, the system can continue to operate; however, a measurement that approaches the minimum or maximum of a range indicates a potential problem. You can maintain normal operation by anticipating and correcting environmental conditions before they exceed the maximum operating range.

Verify the site power for the type of device you are installing. Power requirements are useful for planning the power distribution system needed to support the storage router. Heat dissipation is an important consideration for sizing the air-conditioning requirements for an installation. See Tabl e 20 in Appendix A for power and heat ratings for the SR2122-2.

Caution: To prevent a loss of input power, verify that the total maximum load

on the circuit supplying power to the power supply is within the current ratings of the wiring and breakers.

Installing the Storage Router

You can install the SR2122-2 on a table or a shelf, or in an equipment rack. The following sections describe the steps required to install the storage router:

■ Installing on a Table or a Shelf

Connecting to Gigabit Ethernet and Fibre Channel Ports

The Gigabit Ethernet ports, GE 1 and GE 2, use MT-RJ-type or LC-type fiber-optic SFP modules and cables. The Fibre Channel ports, FC 1 and FC 2, use LC-type fiber-optic SFP modules and cables. When connecting a cable to a fiber-optic SFP module, make sure that you firmly press the cable plug into the socket. The upper edge of the plug must snap into the upper front edge of the socket and you should hear the plug click when it is locked into the socket. To make sure that the plug is locked into the socket, gently pull on it.

To disconnect a plug from a socket, press the trigger on top of the plug, releasing the latch. You should hear a click, which indicates that the latch has released. Carefully pull the plug out of the socket.

Note: When you disconnect the fiber-optic cable from the module, grip the body of the

connector. Do not grip the connector jacket-sleeve. Pulling on the sleeve can, over time, compromise the integrity of the fiber-optic cable termination in the connector.

Dirt or skin oils may have accumulated on an MT-RJ plug faceplate (around the optical-fiber openings), which can generate significant attenuation and reduce the optical power levels below threshold levels so that a link cannot be made. To clean an MT-RJ plug faceplate, follow this procedure:

1. Using a lint-free tissue soaked in 99 percent pure isopropyl alcohol, gently wipe the faceplate.

2. Remove any residual dust from the faceplate with compressed air before installing the cable.

Note: When fiber-optic cable plugs and SFP module receptacles are disconnected

from each other, place dust covers on them.

■ Troubleshooting a Network or Fibre Channel Port Connection

■ Contacting Customer Service

49IP Storage Router SR2122-2 User Guide

Troubleshooting

Solving Problems at the Component Level

The key to troubleshooting the SR2122-2 is to isolate the problem on a specific storage router component. The first step is comparing what the storage router is doing to what it should be doing. Because a startup problem is usually attributed to a single component, it is more efficient to isolate the problem to a subsystem rather than troubleshoot each separate component in the storage router.

The SR2122-2 consists of the following subsystems:

■ The power supply operates whenever system power is on (see

“Troubleshooting the Power Supply” on page 52.

■ The chassis fan assembly operates when the system power is on. The fan may

continue to operate even when the power supply shuts down the storage router because of an over temperature or over voltage condition. The fan does not operate if the power switch is off.

The following are simple checks you can make to determine if there is a fan problem:

— Listen to the fan assembly to determine if it is operating.

— Check for any obstructions restricting airflow through the storage router.

If you determine that the fan assembly is not operating properly, contact a customer service representative.

50 IP Storage Router SR2122-2 User Guide

Identifying Startup Problems

Observe the operation of the SR2122-2 and its front-panel LEDs to determine startup problems. LEDs indicate storage router status in the startup sequence. By checking the LEDs, you can determine when and where the storage router failed in the startup sequence.

To power up the storage router:

1. Listen for the chassis fan assembly operation. If it does not operate, see “Troubleshooting the Power Supply” on page 52. If you determine that the power supply is functioning normally and that the fan assembly is faulty, contact a customer service representative. If the fan assembly does not function properly at initial startup contact a customer service representative. There are no installation adjustments that you can make.

2. Check the POWER LED on the front panel. The POWER LED turns on immediately when power is on. The LED remains on during normal storage router operation. If the LED is not on, see “Troubleshooting the Power

Supply” on page 52.

3. Check the STATUS and FAULT LEDs on the front panel. See “Front-Panel

LEDs” on page 23 for LED descriptions.

4. Check the network and Fibre Channel port LEDs on the front panel. See the “Front-Panel LEDs” on page 23 for LED descriptions. If a network or Fibre Channel port LED indicates a problem with the port connection, see “Troubleshooting a Network or Fibre Channel Port Connection” on page 53.

Troubleshooting

5. Verify that the PC terminal emulation program is set correctly and that the PC is connected properly to the console port. Also, verify at the PC terminal emulation program display that the storage router has started up properly (for example, a prompt for starting a configuration wizard or a CLI prompt).

6. Contact a customer service representative for instructions if a status LED indicates a failure or if the PC connected to the console port indicates an incomplete boot-up process.

51IP Storage Router SR2122-2 User Guide

Troubleshooting

Troubleshooting the Power Supply

To help isolate a power problem:

1. Check the POWER LED.

■ If the POWER LED is off, verify that the power switch is in the on

position.

■ If the power switch is on, unplug the power cord and then plug the power

cord back in.

■ If the POWER LED remains off, continue with the next step.

2. Connect the power cord to another power source if one is available.

■ If the POWER LED comes on, the problem is the first power source.

■ If the POWER LED is off after you connect the power supply to a new

power source, replace the power cord.

■ If the POWER LED still fails to light when the storage router is connected

to a different power source with a new power cord, the power supply is probably faulty.

3. If you are unable to resolve the problem, contact a customer service representative for instructions.

SCSI Routing Overview

SCSI routing provides IP hosts with access to FC storage devices as if the storage devices were directly attached to the hosts, with access to devices being managed primarily in the storage router. An iSCSI target (also called logical target) is an arbitrary name for a group of physical storage devices. The iSCSI targets are created and mapped to physical storage devices attached to the storage router. The SR2122-2 presents the iSCSI targets to IP hosts (iSCSI initiators) as if the physical storage devices were directly attached to the hosts. With SCSI routing, storage devices are not aware of each IP host; the storage devices are aware of the storage router and respond to it as if it were one FC host.

Figure 32: Routing SCSI requests and responses for SCSI routing

Each host that requires IP access to storage via an IP Storage Router 2122-2 needs to have a compatible iSCSI driver installed. Using the iSCSI protocol, the iSCSI driver allows an IP host to transport SCSI requests and responses over an IP network. From the perspective of a host operating system, the iSCSI drive appears to be a locally attached SCSI or Fibre Channel drive to the host.

SCSI routing consists of the following main actions (see Figure 33):

hosts and the SR2122-2

■ Routing SCSI requests and responses between hosts on an IP network and FC

storage

■ Transporting SCSI requests and responses between the SR2122-2 and FC

storage

Basic Network Structure

Figure 34 shows the basic structure of a SCSI routing network. IP hosts with

iSCSI drivers access the storage routers through an IP network connected to the Gigabit Ethernet interface of each storage router. The storage routers access storage devices connected to the Fibre Channel interfaces of each storage router. A management station manages the storage routers through an IP network connected to the management interface of each storage router. For high availability (HA) operation, the storage routers communicate with each other over two networks: the HA network connected to the HA interface of each storage router and the management network connected to the management interface of each storage router.

SCSI Routing Mapping and Access Control

SCSI routing occurs in the storage router through the mapping of physical storage devices to iSCSI targets. An iSCSI target (also called logical target) is an arbitrary name for a group of physical storage devices. You can map an iSCSI target to multiple physical devices. An iSCSI target always contains at least one Logical Unit Number (LUN). Each LUN on an iSCSI target is mapped to a single LUN on a physical storage target.

You can choose either of two types of storage mapping: target-and-LUN mapping or target-only mapping. Target-and-LUN mapping maps an iSCSI target and LUN combination to a physical storage target and LUN combination. Target-only mapping maps an iSCSI target to a physical storage target and its LUNs.

With target-and-LUN mapping, an iSCSI target name and iSCSI LUN number are specified and mapped to the physical storage address of one LUN; either a WWPN + LUN (World Wide Port Name + LUN) combination, a LUN ID (unique LUN identifier), or a LUN serial number. If the LUN is available, it is made available as an iSCSI LUN and numbered with the iSCSI LUN number specified. For example, if an iSCSI target and iSCSI LUN specified as Database, LUN 9 were mapped to the physical storage address, WWPN 3100112233445566, LUN 12, then LUN 12 would be available as one iSCSI LUN. An iSCSI driver would see the iSCSI target named Database, with one iSCSI LUN identified as LUN 9. The iSCSI LUN would appear as one storage device to a host (see Tab le 5 ).

With target-only mapping, an iSCSI target name is specified and mapped to the physical storage address of a storage controller only; a WWPN. Any LUNs that are available in the storage controller are made available as iSCSI LUNs and are numbered the same as the LUNs in the storage controller. For example, if an iSCSI target specified as Webserver2000 were mapped to the physical storage address WWPN 3100112233445577, and LUNs 0 through 2 were available in that controller, those LUNs would become available as three iSCSI LUNs. An iSCSI driver would see the iSCSI target named Webserver2000 as a controller with three iSCSI LUNs identified as LUN 0, LUN 1, and LUN 2. Each iSCSI LUN would appear as a separate storage device to a host.

Software Overview

Access for SCSI routing is controlled in the IP hosts and the storage router. In an IP host, the Gigabit Ethernet IP address of the SCSI routing instance in the storage router with which the host is to transport SCSI requests and responses is configured in the iSCSI driver. In a storage router, access is controlled through an access list and a VLAN identifier (VID) number of the hosts. Additionally, access can be further controlled in the storage router through authentication. See “Authentication Overview” on page 78 for more information about authentication.

An access list enables access to storage devices attached to the storage router with any combination of host IP address(es), CHAP user name(s), or iSCSI name(s). An access list contains these combinations. Host VID enables access to storage devices according to the VID of each host. See “VLAN Access Overview” on page 75 for more information about VLAN access.

For each iSCSI target you can associate one access list allowing read/write access, and one access list allowing read-only access. See Chapter 8, “Configuring SCSI

Routing” for more information about read/write and read-only access.

You can use a combination of access lists and VIDs to configure access in the storage router; that is, you can specify that certain hosts according to IP address in a VLAN can access storage devices attached to the storage router.

Once the access is configured in the hosts and the storage router, and once the storage mapping is configured in the storage router, the storage router routes SCSI requests and responses between hosts and the mapped storage devices.

Figure 35 represents the concept of storage mapping and access control for SCSI

routing. In the figure, the SR2122-2 provides three IP hosts with IP access to disk drives across four disk controllers. The storage router contains two SCSI routing instances: one configured with IP address 10.1.2.3 for the Gigabit Ethernet interface and the other with IP address 10.1.2.4. The iSCSI drivers in each IP host are configured to access those SCSI routing instances by their IP addresses through the Gigabit Ethernet interface. An access list in the storage router or VID (or both) specifies that hosts A, B, and C are allowed to access the mapped storage devices. From the perspective of a host, each disk drive mapped to it appears as a locally attached disk drive. Tab le 7 shows the correlation between an access list and/or VID, the Gigabit Ethernet IP addresses of the SCSI routing instances, and the storage device mapping.

66 IP Storage Router SR2122-2 User Guide

Note: The purpose of Figure 35 and Table 7 is to illustrate the concept of storage

mapping and access control. The IP addresses will vary according to each site. Similarly, the type of storage addressing (for example, LUNWWN, WWPN + LUN or LUN serial number) will vary according to the types of storage and the types of storage addressing preferred at each site.

FCIP Overview

Fibre Channel over IP (FCIP) enables SR2122-2 Storage Routers to provide connectivity between FC hosts and FC storage devices over an IP network.

To deploy FCIP, two SR2122-2 Storage Routers are required. Each system is configured for FCIP and connected to a SAN (or to any FC host or FC device). The peer systems are connected to each other through an IP network.

An FC host or FC device needs no additional hardware or software to access storage devices via an SR2122-2 Storage Router deployed for FCIP.

To configure an SR2122-2 Storage Router deployed for FCIP you need a basic understanding of the following concepts:

■ Using FCIP to Route Fibre Channel Packets

■ FCIP Network Structures

Using FCIP to Route Fibre Channel Packets

With FCIP, peer systems transport FC frames over an IP network. From the perspective of the SANs the storage devices accessed through the peer systems appear to be part of one unified SAN.

Once configured, FCIP instances on each system become active and establish their connectivity via the IP network. The storage devices in one SAN access the storage devices in the connected SAN using FC frames, which are encapsulated in IP packets by the FCIP instance, and transmitted to the peer system. The peer FCIP instance strips the IP packet data and passes only the FC frames over the FC interfaces to the storage devices.

69IP Storage Router SR2122-2 User Guide

Software Overview

The peer systems deployed for FCIP must be configured to use the TCP protocol. TCP protocol uses standard TCP flow control and error recovery algorithms and should be used if you require a standards-based FCIP implementation or connect to a non-SR2122-2 peer.

With the TCP protocol one FCIP instance must be configured as the TCP client; the other FCIP instance must be configured as the TCP server. The only difference between FCIP instances configured as TCP client and TCP server is which FCIP instance initiates the connection: the TCP client initiates the connection.

FCIP transports FC frames between SANs by performing the following actions (Figure 37):

■ Transporting FC frames between a SAN and an SR2122-2 that is deployed for

FCIP

■ Encapsulating FC frames in IP packets and transporting the IP packets to a

peer SR2122-2 that is deployed for FCIP

■ Receiving IP packets and transporting as FC frames between the peer

SR2122-2 and a connected SAN

Note that FC traffic is carried over the IP network in such a way that the FC fabric and all FC devices on the fabric are unaware of the presence of the IP Network.

FCIP Network Structures

This section describes typical FCIP network structures. In all of these examples a management station (not shown) manages the storage routers through an IP network connected to the management interface and/or HA interface of each storage router.

Figure 36 represents a basic, non-redundant structure of an FCIP network

configuration. In this example an FC host or FC device connects to one or more Fibre Channel interfaces of each peer SR2122-2 Storage Router deployed for FCIP. Each SR2122-2 connects to the IP network through one of its Gigabit Ethernet interfaces. Through the IP network each FCIP instance accesses its peer, thereby connecting the SANs.

Figure 38 shows a slightly more complex FCIP network: a redundant WAN FCIP

configuration. In this example configuration, an FC host or FC device connects to one or more Fibre Channel interfaces of each peer SR2122-2 Storage Router deployed for FCIP, and each SR2122-2 connects to two separate IP networks through each of its Gigabit Ethernet interfaces. Through the IP network, each FCIP instance accesses the peer storage router deployed for FCIP, connecting the SANs. In this configuration, IP A and IP B are redundant paths, so that the loss of connectivity via either path does not cause a loss of connectivity between the SANs.

Note: For multiple paths between SANs, multiple pairs of systems deployed for FCIP

need to be connected to the FC hosts or FC devices. However, multiple SR2122-2 Storage Routers deployed for FCIP cannot be configured in an HA cluster. It is assumed that the multipath management is being done by an entity outside the SR2122-2 (for example, by management applications on the FC host or storage devices).

Figure 40 shows an alternative network structure for FCIP in which FCIP tunnels

are established from two SANs aggregated to a central site. The SR2122-2 at the central site has one FCIP instance set up for SAN 1 and the other FCIP instance set up for SAN 2.

Mixed Mode Overview

When the SR2122-2 is deployed for SCSI routing you can optionally configure one of the internal FC initiator interfaces for FCIP. When it is deployed for FCIP, one of the internal FC initiator interfaces can be configured for SCSI routing. This mixed mode deployment allows the storage router to provide IP hosts with access to the FC storage via one initiator interface and FCIP connectivity for FC hosts and FC storage devices via the other initiator interface.

Figure 41 shows a storage router deployed for mixed mode, with one internal FC

initiator interface dedicated to SCSI routing and the other internal interface dedicated to FCIP.

When the storage router is deployed for mixed mode, all of the features and functionality of the primary deployment mode (SCSI routing or FCIP), and the additional mode, are available.

Basic Network Structure

When a storage router is deployed for SCSI routing and FCIP, IP hosts with iSCSI drivers access the storage router through the IP network connected to the storage router’s Gigabit Ethernet interfaces. The storage router accesses the storage devices or intelligent storage array connected to the Fibre Channel interfaces. Access to the FC interfaces is made through the internal FC initiator interface configured for iSCSI traffic.

The internal FC initiator interface configured for FCIP allows the FC hosts or FC devices to connect to one or more Fibre Channel interfaces of the peer systems, which are connected to the IP network through a Gigabit Ethernet interface. Through the IP network, each FCIP instance accesses its peer, thereby connecting the SANs. Redundant network structures are also supported.

A management station manages the storage router through an IP network connected to the management interface. A storage router deployed for SCSI routing and FCIP can also participate in a cluster to provide HA operations for SCSI routing.

VLAN Access Overview

Software Overview

Storage router VLAN access provides IP hosts with access to storage devices according to the VLAN to which each host belongs.

Figure 42 shows a sample network that employs storage router VLAN access. In

the figure, a storage router Gigabit Ethernet interface is connected to an IP network through an IEEE 802.1Q trunk; the storage router Fibre Channel interfaces are connected to storage devices 1, 2, and 3. The storage router is configured with two SCSI routing instances named SR100 and SR200. The IP network contains two VLANs: VLAN 100 and VLAN 200. The SCSI routing instance, SR100, is configured to allow the hosts in VLAN 100 to access storage devices 1 and 2. The SCSI routing instance, SR200, is configured to allow the hosts in VLAN 200 to access storage device 3.

Figure 42: VLAN access overview

If the storage router is used in a switched network environment, configure the storage router using the proprietary VLAN Trunking Protocol (VTP). With VTP, the storage router will exchange VTP packets with an externally attached switch to dynamically learn about the VLANs that are accessible in the IP network. The storage router then uses VTP to propagate VLAN information around the switched network using layer 2 multicast packets.

If the storage router is used in a non-switched network environment, configure the storage router for VLAN without using VTP. The storage router does not exchange VTP packets to learn about the VLANs in the network. Instead, you must manually assign VLANs in the network with a VLAN identifier (VID) number. You can optionally assign each VLAN with a unique name and manually set the MTU size.

If the storage router participates in a cluster, the VLAN information configured for the storage router is propagated to all storage routers in the cluster.

The SR2122-2 uses IEEE 802.1Q standard for VLAN encapsulation. With 802.1Q encapsulation, VLAN information is carried in packets sent and received through the storage router Gigabit Ethernet interface. These packets contain the VID and other VLAN information needed for VLAN members to participate in a VLAN.

A VLAN is granted access to storage devices via a SCSI routing instance configured in the storage router. The iSCSI targets assigned to the SCSI routing instance determine which storage devices the VLAN can access.

76 IP Storage Router SR2122-2 User Guide

Gigabit Ethernet Interface Overview

Each of the two 1-Gigabit Ethernet interfaces on the SR2122-2 (GE 1 and GE 2) provide the following capabilities:

■ Multiple IP addresses per SCSI routing instance—allows IP hosts to connect

to SCSI routing instances via one or more IP addresses. Each Gigabit Ethernet interface can be configured with up to 12 unique IP addresses which provides a maximum of 24 unique IP addresses per SR2122-2 Storage Router. If VLAN access is used, the maximum number of unique IP addresses per Gigabit Ethernet interface increases to 16. This provides a maximum of 32 unique IP addresses per SR2122-2 Storage Router when configured with VLAN.

■ Assignment of a secondary interface per SCSI routing instance—allows the

same IP address to be assigned to each Gigabit Ethernet interface; one interface is assigned as primary and one interface is assigned as secondary. If the primary Gigabit Ethernet interface loses connection to the host and if the secondary connection is assigned and still connected, the IP address moves to the secondary Gigabit Ethernet interface which then becomes active.

■ Assignment as an interface to an FCIP peer—allows assignment of an IP

address as a primary Gigabit Ethernet interface between an FCIP instance and an FCIP peer. Each SR2122-2 can be configured with up to two FCIP instances, and each FCIP instance can be configured with one peer for a maximum of two FCIP peers per SR2122-2 Storage Router when configured for FCIP.

Software Overview

■ Assignment of a secondary interface per FCIP instance—allows the same IP

address to be assigned to each Gigabit Ethernet interface configured for an FCIP instance; one interface is assigned as primary and one interface is assigned as secondary. If the primary interface loses connection to the network and remains down for two seconds, the IP address moves to the secondary Gigabit Ethernet interface, which then becomes active.

■ Assignment as a management IP address—allows each Gigabit Ethernet

interface to have one IP address assigned per logical interface, as a management interface. This IP address is in addition to any multiple IP address(es) per SCSI routing instance or FCIP instance assigned.

■ Assignment of a secondary management IP address—allows the same IP

address to be assigned to each Gigabit Ethernet interface configured as a management interface; one interface is assigned as primary and one interface is assigned as secondary. If connection to the primary Gigabit Ethernet

77IP Storage Router SR2122-2 User Guide

Software Overview

maintenance interface is lost and if the secondary maintenance interface connection is assigned and connected, the IP address moves to the secondary Gigabit Ethernet interface, which then allows management access.

Authentication Overview

Authentication is a software service that is available in each SR2122-2. It provides a method of identifying users (including login and password dialog, challenge and response, and messaging support) prior to receiving access to the requested object, function, or network service. The SR2122-2 supports three types of authentication:

■ iSCSI authentication—provides an authentication mechanism to authenticate

IP hosts that request access to storage. An IP host, acting as an iSCSI initiator, can also verify the identity of an iSCSI target assigned to a SCSI routing instance, which responds to the request, resulting in a two-way authentication.

■ Enable authentication—provides a mechanism to authenticate users

requesting Administrator mode access to an SR2122-2 management session via the CLI enable command or an FTP session.

■ Login authentication—provides a mechanism to authenticate users requesting

access to the SR2122-2 in Monitor mode via the login process from a Telnet session, SSH session or the SR2122-2 console.

Authentication is provided by an AAA (authentication, authorization, and accounting) subsystem configured in each SR2122-2. AAA is an architectural framework for configuring a set of three independent security functions in a consistent and modular manner: authentication, authorization, and accounting. The SR2122-2 Storage Router software implements the authentication function.

AAA authentication is configured by defining a list of authentication services. iSCSI authentication, which uses a AAA authentication services list, can be enabled for specific SCSI routing instances in an SR2122-2.

When iSCSI authentication is enabled, IP hosts (with iSCSI drivers) must provide user name and password information each time an iSCSI TCP connection is established. With two-way authentication, the SCSI routing instance to which an iSCSI target has been assigned responds to the authentication request with an assigned username and password. iSCSI authentication uses the iSCSI CHAP (Challenge Handshake Authentication Protocol) authentication method.

See Chapter 10, “Configuring Authentication” for more information about configuring authentication services.

78 IP Storage Router SR2122-2 User Guide

Cluster Management Overview

You can configure storage routers in a cluster to allow the storage routers to back each other up in case of failure.

Note: A storage router can participate in a cluster only if it is deployed for SCSI

routing.

A storage router cluster consists of two SR2122-2 storage routers connected as follows:

■ Connected to the same hosts

■ Connected to the same storage systems

■ Connected to each other through their management and high availability (HA)

interfaces

In a cluster, storage routers continually exchange HA information to propagate configuration data to each other and to detect failures in the cluster. The storage routers exchange HA information through two separate networks: one connected to the management interface of each storage router and the other connected to the HA interface of each storage router. To make sure that HA information is exchanged reliably between storage routers, the storage routers balance the transmission of HA information between the management and the HA interfaces.

Software Overview

A storage router cluster supports up to 12 active instances of SCSI routing. At any given time, an instance of SCSI routing can run on only one storage router in a cluster. The instance continues running on the storage router where it was started until one of the following actions occurs:

■ The instance is explicitly stopped or failed over to the other storage router in

the cluster.

■ The instance automatically fails over to another storage router because an

interface is unavailable or another software or hardware problem occurs.

See Chapter 11, “Configuring a High Availability Cluster” for more information about configuring a high availability cluster.

Configuring the Storage Router

Initial System Configuration Script

The initial system configuration script runs on the CLI and ensures that a few required values are entered to make the SR2122-2 operational. When you first power up the storage router and after the initial boot process, the script will run automatically on the CLI session running on the terminal emulation program via an EIA/TIA-232 console connection.

After the first running of the script, the script will run automatically whenever the storage router is not configured with an IP address for the management interface, due most likely to a clear conf command, which requires you to reconfigure the system.

The initial system configuration script provides explanatory text before prompting you to enter configuration values. The values asked for by the script are determined by the configuration deployment option entered for the first prompt.

Table 12 lists the configuration items in the order they will appear in the script.

Table 12: Configuration items in Initial System Configuration Script

When the script completes, the system automatically reboots. When the command prompt returns, continue configuration with the setup configuration wizard.

88 IP Storage Router SR2122-2 User Guide

Running the Setup Configuration Wizard

The Setup Configuration Wizard is available from the CLI and is a script consisting of a series of prompts asking you to enter values to provide a basic system configuration for your storage router. You will be asked to enter values to configure the following:

■ Management interface — includes primary and secondary DNS servers

■ Date and time — includes time zone and NTP server

■ Network management access — includes SNMP

■ Management access — includes passwords and system administrator contact

information

■ System administrator contact information

■ SCSI routing — this section of the wizard only appears if SCSI routing was

the configuration deployment selected in the initial system configuration script; if you are using the VLAN service, do not configure SCSI routing with the Setup Configuration Wizard

■ FCIP — this section of the wizard only appears if FCIP was the configuration

deployment selected in the initial system configuration script

You can run the Setup Configuration Wizard through an EIA/TIA-232 console interface connection, or through a Telnet session using the management interface if the IP address is already configured in the storage router. If you choose to complete the configuration using the management interface, use the default password, hp, to establish your CLI session.

Configuring the Storage Router

The values entered for the Setup Configuration Wizard are saved at the end of the wizard script. To quit the configuration wizard at any time without saving changes, press Ctrl-C, and reboot the storage router to restore previous values.

Note: The factory default listening port used for iSCSI traffic is 3260. This is a port

number assigned by IANA. You can change this value for your network configuration if needed. See the

Reference Guide

HP StorageWorks IP Storage Router 2122-2 Command Line Interface

for details.

89IP Storage Router SR2122-2 User Guide

Configuring the Storage Router

Use the following procedure to start the Setup Configuration Wizard:

1. enable — Enter Administrator mode. If prompted for an Administrator password, use the default password, hp.

Note: Passwords are cluster-wide configuration elements and apply to all storage

routers in a cluster. If the SR2122-2 joined an existing cluster during initial configuration, enter the Administrator mode password already configured for the cluster.

2. setup — Start the setup configuration wizard. The wizard will ask you to choose one of the two levels:

■ The novice level provides information before the prompt explaining what

■ The expert level does not provide the explanatory text.

Respond to the prompts using your First-Time Configuration Checklist.

■ For multiple choice questions, the choices are shown in square brackets

■ For values requiring a specific format, the required format is shown in

is being requested.

square brackets.

■ If values have already been entered (for instance, via the initial system

configuration script), the current values saved in the system are shown in square brackets.

■ Default values are shown in parentheses within the square brackets.

■ If you want to accept the current or default value, press Enter.

■ If there is no default and you want to bypass the question (that is, you do

not want to change or provide a value), press Enter.

If you configured any interfaces or identified any servers to the IP Storage Router that are outside the storage router management subnet, you must update the storage router route table with the appropriate gateways that will provide access to these interfaces or servers (use the ip route command), or configure the SR2122-2 for RIP listening to dynamically learn IP routes. See Chapter 6,

“Configuring System Parameters.” for details on adding the static routes or

configuring the SR2122-2 for RIP listening.

90 IP Storage Router SR2122-2 User Guide

You can use the setup command again to change these basic configuration parameters. You can also use the command line interface (CLI) or the web-based GUI to make changes to the basic storage router configuration or to configure the SR2122-2 more extensively. To access the web-based GUI, point your browser to the storage router management interface IP address.

Introducing the CLI

The CLI is available via a Telnet session to the management interface. It is also available via a direct EIA/TIA-232 connection on the console interface. The CLI provides commands to perform all necessary storage router management functions, including software upgrades and maintenance.

All CLI commands are capable of prompting for further information as the user types.

■ Pressing the Tab key completes the current command word at any point after it

is unique.

■ Pressing the question mark (?) key lists all of the options available at that

point in the command syntax.

■ Each command or keyword can be truncated at any point after it is unique.

Configuring the Storage Router

For complete information on all storage router commands, see the HP StorageWorks IP Storage Router 2122-2 Command Line Interface Reference Guide.

Character Case Sensitivity in the CLI

CLI commands, keywords, and reserved words are not case-sensitive. Commands, keywords, and reserved words can be entered in upper and lower case. User-defined text strings can be defined in both upper and lower case (including mixed cases) and is preserved in the configuration.

Command Modes

The storage router management interface is password protected. You must enter passwords when accessing the storage router via Telnet (for the CLI) or web-based GUI.

There are two levels of authority:

■ Monitor mode allows view-only access to the storage router status and

system configuration information.

91IP Storage Router SR2122-2 User Guide

Configuring the Storage Router

■ Administrator mode allows the user to configure and actively manage the

storage router, its access lists and SCSI routing instances, and the storage router cluster.

Passwords for Monitor and Administrator mode can be initially configured through the Setup Configuration Wizard (see “Running the Setup Configuration

Wizard” on page 89). The factory default password for both modes is hp.

Note: Passwords are shared cluster-wide and when configured on the first storage

router in the cluster, will be shared with any other storage router that joins the cluster.

Command Prompt

The CLI command prompt includes the storage router system name. An asterisk ( * ) appears at the beginning of the prompt if the system configuration has been modified but not saved.

Reserved Words

Reserved words cannot be used as values or names in CLI commands. Words that are used as commands or as keywords in commands are reserved words. The following are additional reserved words in the CLI.

■ acl

■ canonical

■ iprouter

■ iptan

■ loglevel

Show CLI Command

Use the show cli command to display the complete CLI command syntax tree, along with helpful information about command parameters and arguments. Only valid commands will display for the current command mode of your IP Storage Router.
