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 Hardware Installation Guide.

Collecting Required Information

Use the Cisco SN 5420 Storage Router Installation Checklist form (Table 2-1) to help you gather the system and network information that is needed for first time storage router configuration.

The following information is required:

•Management interface IP address and network mask—The IP address and subnet mask of the storage router management interface.

---

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

---

•Current date, time and time zone.

The following information is optional:

•High availability (HA) IP address and network 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 will participate in a cluster, the HA IP address is mandatory; if the SN 5420 is a stand-alone machine, it is optional.

---

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

---

•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 have the same cluster name.

•System name—The name you want to use for this system. If you use the services of a domain name server (DNS), this is the same name you will enter and associate with the management interface.

•Monitor-level password—A password for users who will monitor storage router operations only. The default password is cisco.

•Administrator-level password—A password for users who will configure and administer the storage router. The default password is cisco.

•Primary DNS IP address—Required, if you refer to any other server via name rather than IP address.

•Secondary DNS IP address—Optionally, a backup domain name server from which the storage router can request services if the primary DNS is not available.

•Primary SNMP trap manager IP address—Required, if you wish to use SNMP notifications.

•Secondary SNMP trap manager IP address—An optional IP address to which the storage router can send notifications, if the primary SNMP host is not available.

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

•SNMP SET 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.

•System Administrator contact name, e-mail, phone and page—Basic contact information for the administrator of this storage router. Usage is completely site-specific.

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

•SCSI routing services names—The name of up to four unique instances of SCSI routing services. Names can be up to 32 characters in length.

---

Note If the storage router is going to be a member of a cluster, do not define more than four instances of SCSI routing services 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 SN 5420."

---

•SCSI routing services server interface name, IP address and network mask—the IP address assigned to the specified interface (usually the Gigabit Ethernet interface) which is used by servers requiring access to storage devices through the storage router.

•SCSI routing services device interface— the name of the Fibre Channel interface.

Once you have completed the checklist, you are ready to continue with first time configuration of the SN 5420 Storage Router.

Connecting a Console

Connect a PC with a terminal emulation program to the RS-232 console interface according to the Cisco SN 5420 Hardware Installation Guide. Then make sure that the terminal emulation program is configured as follows:

Table 2-2 Terminal Emulation Configuration

Setting	Value
Terminal Mode	VT-100
Baud	9600
Parity	No Parity
Stop Bits	1 Stop Bit

Entering the Management Interface IP Address

The SN 5420 requires an IP address for the management interface before beginning configuration. At the command prompt, enter the management interface IP address and then reboot the storage router.

Use the following table to enter the appropriate commands.

	Command	Description
Step 1	set mgmt ipaddress A.B.C.D/bits	A.B.C.D is the IP address of the SN 5420 management interface. /bits is the subnet mask, in CIDR style.
Step 2	reboot	Reboots the SN 5420 Storage Router.

When the command prompt returns, continue configuration with the Setup Wizard.

Running the Configuration Wizard

At the command prompt, enter parameters using the CLI setup command. The setup command initiates a series of prompts requesting that you enter parameters. Respond to the prompts, using the information from your Cisco SN 5420 Storage Router Installation Checklist.

Use the following table to enter first-time parameters using the setup command. For more details on how to use the setup command, see the setup command description in "Command Line Interface Command Reference."

	Command	Description
Step 1	enable	Enter Administrator mode.
Step 2	setup	Initiates setup wizard. Enter parameters according to the prompts.

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 add route gw command in "Command Line Interface Command Reference," for details.

---

Note You can enter all first-time configuration parameters through the RS-232 console interface connection. However, after entering the management interface configuration information, you could reboot the system and complete configuration through a Telnet session using the management interface.

If you choose to complete configuration in this manner, use the default password cisco to establish your CLI session. Then follow the same commands as shown in the previous table. When prompted for an Administrator password, use the default password cisco.

---

After you have completed the first-time configuration, you can use the setup command again, at a later time, to change these basic configuration parameters. However, to change the storage router configuration more extensively, use the command line interface (CLI) or the web-based GUI. To access the web-based GUI, point your browser to the SN 5420 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 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 follow a simple structure, and are capable of prompting for further information as the user types. Pressing the Tab key completes the current word being typed up to a point of ambiguity. Pressing the Question Mark (?) key lists all of the options available at that point in the command line, along with a brief description of the meaning of the options. Each word may be truncated at any point after it is unique.

The CLI supports the use of the following special keys for the described functions:

Table 2-3 Special Keys

Key	Function
?	List choices
Backspace or Delete	Delete previous character
Tab	Command-line completion
Ctrl-A	Go to the beginning of the line
Ctrl-B or Left Arrow	Go backwards one character
Ctrl-D	Delete current character
Ctrl-E	Go to the end of the line
Ctrl-F or Right Arrow	Go forward one character
Ctrl-K	Delete from current position to the end of the line
Ctrl-N or Down Arrow	Go to the next line in the history buffer
Ctrl-P or Up Arrow	Go to the previous line in the history buffer
Ctrl-T	Transpose the current and previous character
Ctrl-U	Delete the line
Ctrl-W	Delete the previous word

CLI Structure

The CLI provides the following basic commands (Table 2-4):

Table 2-4 Basic Commands  

Command	Description
add	Add configuration to a previously created entity
clearconf	Run the wizard to return most configuration settings to factory defaults
create	Create a named entity
delete	Delete selected entities that were created or added
failover	Cause an instance of a SCSI routing service to run on another storage router
save	Save all configuration, or configuration for named entities
set	Set various parameters of a created entity
setup	Run the SN 5420 configuration wizards
show	Display configuration and operational data
start	Start an instance of a SCSI routing service
stop	Stop an instance of a a SCSI routing service

An entity is an instance of SCSI routing services or an access list. Entities are created and assigned arbitrary names by the user, which are then used in subsequent add, set, save, and show commands. Wherever possible, commands follow a similar word pattern.

Accompanying basic commands are other commands necessary for operating the SN 5420 (Table 2-5):

Table 2-5 Other Operational Commands

Command	Description
download	Download new software to the SN 5420
enable	Enter Administrator mode
exit	Leave Administrator mode and return to Monitor mode
help	Display help text for the CLI
import	Import a previously saved system configuration or reset an import pending flag
logout	Terminate the current management session
reboot	Cause the SN 5420 to shutdown and reboot
restore from	Restore a system configuration file to memory

For complete command descriptions and syntax information, see "Command Line Interface Command Reference."

Character Case in the CLI

The CLI is case sensitive. All keywords must be entered in lower case. Any user-defined strings, such as names or descriptions, may appear in any case, including mixed case. Case information for user-defined strings 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 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 services, and (if applicable) the SN 5420 cluster.

Passwords for Monitor and Administrator mode access are assigned during initial system setup (see "Running the Configuration Wizard" section). The factory default passwords for both modes is "cisco".

Command Prompt

The CLI command prompt includes the SN 5420 system name. An asterisk is added to the beginning of the prompt if the system configuration has been modified but not saved.

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 SN 5420, or the SCSI routing services running on the storage router or cluster, you need to enable Administrator mode.

---

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

Step 5 Issue the appropriate CLI commands to complete the required actions.

---

Where to Go Next

If you did not run the complete SN 5420 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 ran the complete SN 5420 configuration wizard (see "Running the Configuration Wizard" section for details), you can begin configuring your SCSI routing services using the procedures described in "Configuring SCSI Routing."

---

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 your SCSI routing services.
