Prerequisite Tasks

Before configuring the SN 5420 Storage Router for the first time, make sure you have completed the hardware installation according to the Cisco SN 5420 Storage Router Hardware Installation Guide.

Collecting Configuration Information

Use the Cisco SN 5420 Storage Router First-Time Configuration Checklist (Table 2-2) to help you gather the system and network information that is needed for the first-time configuration of your SN 5420 Storage Router. The items in the checklist are based on the information requested by the initial system configuration script and the setup configuration wizard. Refer to Table 2-1 for information on the configuration items needed for first-time configuration.

Table 2-1 Collecting Configuration Information 

Configuration Item
Description
Required or Optional

Configuration deployment option

The SN 5420 can be configured for one of three kinds of deployments:

1. SCSI routing (SN 5420 enables iSCSI hosts to access Fibre Channel devices. SN 5420 manages access to the Fibre Channel devices.)

2. Transparent SCSI routing (SN 5420 enables iSCSI hosts to access Fibre Channel devices. SN 5420 does not manage access to the Fibre Channel devices.)

3. iSCSI SAN interconnect (SN 5420 enables Fibre Channel hosts to access iSCSI devices.)

Required

Management interface IP address and subnet mask

The IP address and subnet mask of the storage router management interface.

Note The management interface for each storage router in a cluster must be on the same IP subnet.

Required

Static route for management interface

The destination IP address with subnet mask and then the gateway IP address.

Required if SN 5420 is managed from a subnet other than the one to which it is physically attached

System name

The name you want to use for the storage router. If you use the services of a domain name server (DNS), the system name is the same name you will enter and associate with the management interface. Maximum length is 19 characters.

Required

High availability (HA) configuration

The SN 5420 can run in either standalone or clustered mode. The default is clustered. Standalone mode is recommended if the storage router is not intended to provide high availability along with other SN 5420s or if the storage router is intended for iSCSI SAN interconnect.

Required for SCSI routing only

High availability (HA) cluster name

The name of the cluster in which the storage router is to participate. Clusters are multiple storage routers that back each other up in case of hardware or software failure. All SN 5420s that participate in a cluster must have the same cluster name.

Required only if clustered was specified for the HA configuration

High availability (HA) IP address and subnet mask

The IP address and subnet mask of the storage router HA interface. The HA interface and management interface must be on unique IP networks. If the SN 5420 is to participate in a cluster, the HA IP address is required; if the SN 5420 is a stand-alone machine, it is optional.

Note The HA interface for each storage router in a cluster must be on the same IP subnet.

Required only if clustered was specified for the HA configuration

Gigabit Ethernet interface IP address of SCSI routing or FC server instance

The IP address and subnet mask for the Gigabit Ethernet interface that the SCSI routing or FC server instance presents on an IP network.

Required

Gigabit Ethernet interface IP address of SCSI routing instance on remote SN 5420

The IP address assigned to the Gigabit Ethernet interface for the SCSI routing instance on remote SN 5420.

Required for iSCSI SAN interconnect only

Primary DNS IP address

The IP address of the primary domain name server to be accessed by the storage router. Required if you refer to any other server via name rather than IP address.

Optional

Secondary DNS IP address

A backup domain name server from which the storage router can request services when the primary DNS is unavailable.

Optional

NTP server IP address

The IP address of the NTP server available to the storage router. This allows the storage router to keep the date and time synchronized with the rest of the network.

Optional

Time zone, current date and time

The format for the date is mm/dd/yyyy, and the time is hh:mm:ss.

Optional

Enable Telnet on all interfaces

Enable Telnet access on all interfaces. By default, Telnet access is enabled on only the management interface.

Optional

SNMP read community name

The name of the community having read-only access to the storage router network. The SN 5420 will respond to this community's GET commands. The default is public.

Optional

SNMP write community name

The name of the community having write access to the storage router network. The SN 5420 will respond to this community's SET commands. The default is private.

Optional

First SNMP trap manager IP address

The IP address of the first destination host used for SNMP notifications (traps). Required if you wish to use SNMP traps.

Optional

Trap version for first SNMP IP address

The version number of the traps that are to be sent to the first SNMP trap manager IP address. The default is 1.

Optional

Second SNMP trap manager IP address

An optional IP address to which the storage router can send notifications when the first SNMP host is unavailable.

Optional

Trap version for second SNMP IP address

The version number of the traps that are to be sent to the second SNMP trap manager IP address. The default is 1.

Optional

Send authentication failure option

Enable an authentication failure trap to be sent when a user specifies an incorrect community.

Optional

Send link up/down traps option

Enable link up/down traps to be sent for the Management, HA, Gigabit, and/or Fibre Channel interfaces when the link goes up and when it goes down.

Optional

Monitor-level password

A password for users who will only monitor storage router operations. The default password is cisco.

Optional

Administrator-level password

A password for users who will configure and administer the storage router. The default password is cisco.

Optional

Password applied to RS-232 console interface (yes/no)

Choose whether or not the user is required to enter the monitor and administrator password when accessing the storage router via the RS-232 console interface. The default is no.

Optional

System administrator contact information

The name, e-mail address, phone number, and pager number of the system administrator of the SN 5420. Usage is completely site-specific.

Optional

Name of SCSI routing instance

A unique name for a SCSI routing instance. Names of instances can be up to 32 characters in length. A maximum of 12 unique SCSI routing instances are allowed. Only one instance can be named in the setup configuration wizard.

Note If the storage router is going to be a member of a cluster, do not define more than 12 SCSI routing instances across all storage routers in the cluster. For additional information about HA, cluster configuration and failover, see "Configuring a Storage Router Cluster," and "Maintaining and Managing the Storage Router."

Note Do not name the SCSI routing instance with the setup configuration wizard if you are using the VLAN service with your SN 5420. See "Configuring for VLAN," before naming and configuring SCSI routing instances.

Required for SCSI routing only


Once you have completed the first-time configuration checklist, you are ready to continue with the first-time configuration of the SN 5420 Storage Router using the initial system configuration script and the setup configuration wizard.

Connecting a Console

To begin configuration of your SN 5420 Storage Router, use the command line interface (CLI), by connecting a PC with a terminal emulation program to the RS-232 console interface according to the Cisco SN 5420 Storage Router Hardware Installation Guide. Then make sure that the terminal emulation program is configured for a CLI session with the values provided in Table 2-3.

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 SN 5420 Storage Router operational. When you first power on 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 RS-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 the system to be configured again.

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

Table 2-4 lists the configuration items in the order they will appear in the script and which configuration deployment will ask for the configuration item.

Table 2-4 Configuration Items in Initial System Configuration Script

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

Running the Setup Configuration Wizard

The setup configuration wizard is available from the CLI and is a script that consists of a series of prompts asking you to enter values to provide a basic system configuration for your SN 5420. You will be asked to enter values to configure the following:

Management interface (this includes primary and secondary DNS servers)

Time zone, NTP server, current date and time

Network management access (this includes SNMP)

Monitor and administrator passwords

Console interface password

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)

You can run the setup configuration wizard through an RS-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, cisco, to establish your CLI session.

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

Use the following procedure to start the setup configuration wizard.

 
Command
Description

Step 1 

enable

Enter Administrator mode. If prompted for an Administrator password, use the default password, cisco.

Step 2 

setup

Start the setup configuration wizard.

The wizard can run in either of two modes: novice or expert. The novice level provides information before the prompt explaining what is being requested. The expert level does not provide the explanatory text. The wizard will ask you to choose one of the two levels.

Respond to the prompts using your Cisco SN 5420 Storage Router 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 square brackets. If values have already been entered (for instance, via the initial system configuration script), the current value 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), simply press Enter.

If you configured any interfaces or identified any servers to the SN 5420 that are outside the storage router management subnet, you must update the SN 5420 route table with the appropriate gateways that will provide access to these interfaces or servers. See the CLI ip route command in "Command Line Interface Reference," for details.

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 storage router more extensively. To access the web-based GUI, point your browser to the SN 5420 management interface IP address.


Note The web-based GUI is not available for transparent SCSI routing, since this deployment option requires minimal configuration of the SN 5420.


Introducing the CLI

The CLI is available via a Telnet session to the management interface. It is also available via a direct RS-232 connection on the console interface. The CLI provides commands to perform all necessary SN 5420 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 word can be truncated at any point after it is unique.

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 SN 5420 management interface is password protected. You must enter passwords when accessing the SN 5420 via Telnet (for the CLI) or web-based GUI.

There are two levels of authority:

Monitor mode—Allows view-only access to the SN 5420 status and system configuration information.

Administrator mode—Allows the user to configure and actively manage the SN 5420, its access lists and SCSI routing instances, and the SN 5420 cluster.

Passwords for Monitor and Administrator mode can be initially configured through the setup configuration wizard (see "Running the Setup Configuration Wizard" section). The factory default password for both modes is cisco.

Command Prompt

The CLI command prompt includes the SN 5420 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 and the configuration deployment of your SN 5420.

You can choose specific commands to display by specifying desired commands with the show cli command. For example, show cli aaa debug scsirouter displays the syntax tree for all aaa commands, all debug commands, and all scsirouter commands.

Special Keys

The CLI supports the use of special keyboard keys. Table 2-5 lists the special keys and describes their function.

Starting a CLI Management Session

Follow these steps to start a CLI management session via a Telnet connection to the storage router.


Step 1 Establish a Telnet session to the SN 5420.

Step 2 Enter the appropriate password at the logon prompt.

Step 3 (Optional) Enter enable to change to Administrator mode.


Note If you need to make changes to the configuration of the storage router, you need to enable the Administrator mode.


Step 4 (Optional) Enter the Administrator password at the prompt.

Step 5 Issue the appropriate CLI commands to complete the desired task.


Introducing the Web-Based GUI

As an alternative to the CLI, you can configure your SN 5420 Storage Router using the web-based GUI. You can use the GUI for configuration after completing the initial system configuration script, which assures that the SN 5420 management interface is configured with an IP address.

To access the GUI, enter the URL for the SN 5420 by pointing your browser to the SN 5420 management interface IP address using the HTTP protocol (for example, type http://10.1.10.244).


Note The web-based GUI is not available for transparent SCSI routing, since this deployment option requires minimal configuration of the SN 5420.


Logging In

After entering the URL for your SN 5420, a login page will appear. You can log in as monitor or as admin, and you will be asked for your user name and password. See Table 2-6 for the user name and factory default password to use for the two login options. If you already configured new passwords for the monitor and/or the administrator mode, use them when logging in.

Introducing CiscoWorks and CiscoView

CiscoWorks is a web-based application for managing a network. Its Device Manager feature contains CiscoView, which is a graphical SNMP-based tool that provides real-time views of Cisco Systems devices in your network. These views allow you to monitor your devices and network by delivering a continuously updated physical picture of device configuration and performance conditions, with simultaneous views available for multiple device sessions. From CiscoView, you can also open a Telnet session to enter CLI commands to configure the storage router.

Where to Go Next

If you did not run the complete SN 5420 setup configuration wizard, or if you want to make system configuration additions, changes, or corrections, continue with the procedures described in "Configuring System Parameters."

If you are using the VLAN service with the storage router and you entered all desired parameters—except for SCSI routing—with the setup configuration wizard (see "Running the Setup Configuration Wizard" section for details), configure for VLAN using the procedures described in "Configuring for VLAN."

If you do not need to configure for VLAN and the storage router is being deployed for SCSI routing, go directly to "Configuring SCSI Routing," to configure SCSI routing more extensively.

If the storage router is deployed for transparent SCSI routing, go to "Configuring Transparent SCSI Routing," for a summary of the configuration process and to verify the configuration.

If the storage router is deployed for iSCSI SAN interconnect, go to "Configuring iSCSI SAN Interconnect," to further configure the storage router for this deployment, if needed, and to verify the configuration.


Note If you are going to add the storage router to an existing storage router cluster, review the information and procedures in "Configuring a Storage Router Cluster," before configuring SCSI routing.
