Chapter 11 Maintaining and Managing the SN 5428-2 Storage Router
Prerequisite Tasks
Prerequisite Tasks
Before performing any of the storage router maintenance tasks, make sure you have configured system
parameters as described in Chapter 2, “First-Time Configuration,” or Chapter 3, “Configuring System
Parameters.”
Note Certain configuration tasks, such as identifying a location from which to download software, are optional
and may not have been performed during initial configuration. You may perform these tasks at any time,
via the CLI or the GUI. Where necessary, this chapter will identify the relevant tasks and commands.
Installing Updated Software
The SN 5428-2 Storage Router is designed to run on a continual basis without significant maintenance.
However, from time to time, you may need to install updated software.
The SN 5428-2 stores software images (along with configuration files, log files, and other information)
on a local file system. This file system is stored on an internal, non-volatile Flash disk. The
show software version all command displays a list of all software versions stored on the SN 5428-2 and
the amount of disk space available for additional software.
Cisco.com provides registered users access to SN 5428-2 Storage Router software updates. You can
download updated software directly to the SN 5428-2 from Cisco.com via standard HTTP, or via HTTP
using a proxy server. See the “Obtaining Technical Assistance” section on page xiii for details on using
Cisco.com.
You can also use a standard browser to download software updates and associated readme files from
Cisco.com to a location of your choosing. Using the CLI or the web-based GUI, you can then make the
software available from this location (known as the “download location”) to the storage router via HTTP,
HTTP using a proxy server, or Trivial File Transport Protocol (TFTP).
If you plan to use the CLI download software http or download software proxy commands to make
the updated software available to the storage router, the machine hosting the download location must be
running a web server.
If you plan to use the CLI download software tftp command, the machine must be accessible using the
Trivial File Transport Protocol.
If the machine is not running a web server or accessible via TFTP, use the web-based GUI to make the
updated software available to the storage router. (See the online Help for details.)
The download location used for retrieving updated SN 5428-2 software is set using the
software http url, software proxy url, or the software tftp commands. To view the download location
currently specified, use the show software version all command. The resulting display (Example 11-1)
identifies the HTTP URL, Proxy URL, and TFTP host name and other information used to identify the
download location, the current version of software running on the storage router, and the version that
will be used at system restart. In the example, all default locations and related user names and passwords
are set.
