This chapter presents the information and procedures that you need to download new software images to the Cisco 6100 Series system. With the current release of the software, you can download new software images to any of the following modules:
System software download is the method by which you can upgrade the software in each of the Cisco 6100 Series modules. The software download procedure requires a TFTP server. ViewRunner functions as a TFTP server and can handle requests for images from a Cisco 6100 Series system. ViewRunner also allows you to specify any IP address and file path for TFTP so that other TFTP servers can handle file transfer.
The software download process is triggered by menu selection. During the process, the current configuration of the node is saved and is restored upon successful completion. However, as a fail-safe measure, you should use the Configuration Save wizard (see "Configuration Save and Restore") to store the current NVRAM configuration for later retrieval.
The software images are grouped by system software release number. ViewRunner maintains a Release Definition File (RDF) that identifies, for a given software release, the software that is compatible with each hardware module and revision. The SC module and ViewRunner use the RDF to define the Cisco 6100 Series configuration.
The default destination for the images is c:\Program Files\Cisco. This default path applies to each set of images copied to a folder named after the current system release. ViewRunner can upgrade to later releases as long as the RDF and corresponding images have been installed.
Use the following procedure to download new, updated software images to a Cisco 6100
Series system:
Step 1 Access the Update options under the Tools menu on the ViewRunner toolbar (see Figure 13-1).
Step 2 Select Tools > View Cisco 6100 Software Image Data to learn about the current software images. The 6100 Software Images dialog box opens (Figure 13-2). This helps you determine which images are current and which should be updated.
Step 3 Select Tools > Upgrade Cisco 6100 Software from the ViewRunner toolbar (Figure 13-1) to start the Software Download Wizard. ViewRunner displays a progress bar and a description of status while the upgrade is taking place.
The upgrade software command executes only if all of the following points are true:
Step 4 A wizard starts and guides you throughout the process. The first wizard dialog box describes the upgrade procedure (see Figure 13-3). Read each wizard dialog box carefully. Select Next to continue.
 | Caution If you have a BOOTP server, the SC image used is the one specified in the BOOTP table, not the one restored. |
Step 5 ViewRunner searches for all installed releases (.RDF files). It presents a list of installed releases to you (see Figure 13-4). Select one from the list provided or use the Browse button to find the image you want.
Step 6 When you have selected the image to which you wish to upgrade, press Next to continue.
Step 7 ViewRunner presents a system Confirm System Software Version dialog box to you before continuing (see Figure 13-5).
Step 8 The third wizard dialog box identifies a default IP address and IP path. (See Figure 13-6 for an example of this dialog box.) You can change the address and the path. The IP address is the address for the TFTP server. In many cases, this is also the IP address of the PC where ViewRunner is running, because ViewRunner functions as a TFTP server. The path is to the images you want to upgrade.
For remote TFTP with a UNIX server, the path for the remote TFTP server must correspond to the path configuration on the TFTP daemon. For example:
Step 9 Select the local or the remote TFTP server (see Figure 13-6). The local server is the PC currently executing ViewRunner. In this case, ViewRunner uses its own TFTP server to transfer the files. If you select the remote server, you must provide the IP address of the remote PC; ViewRunner uses the TFTP server on that remote machine.
Step 10 Depending on your choice of software to download, various information and warning dialog boxes appear. They present you with the choice of continuing with the upgrade
or canceling.
Step 11 In the example of a Discovered Conditions dialog box (Figure 13-7), images are not available, according to the message. In this case, your only choice is to cancel the download. If the message indicates that images are available, the Next button would not be dimmed and you would press it to continue.
ViewRunner informs you of any conditions that affect the download. If these conditions are acceptable to you, choose Next to continue. If they are not acceptable, press Cancel to stop the process before the download begins.
Step 12 If you continue, the Download Begins dialog box shown in Figure 13-8 appears, informing you that the download procedure is beginning and cannot be interrupted.
Step 13 If you continue, the Software Upgrade Progress dialog box shown in Figure 13-9 displays, showing the progress of the download.
If the SC image changed, ViewRunner uses the Save and Restore Configuration utility to transparently store the NVRAM of the older system. This storage action replaces all configuration items and updates all software images without requiring further user action.
If the SC image does not change, ViewRunner does not execute the Save and Restore Configuration utility. Instead, a Reset SC Module dialog box displays (see Figure 13-10), requiring you to reset the SC module. You can reset the SC module immediately or wait until a later time.
Resetting the SC module propagates image updates to all non-SC modules. Choosing to defer the reset until later allows the system to continue operating without a service interruption until an SC module reset triggers completion of the upgrade.
