This chapter provides information on the Content Distribution Manager (CDM) features that enable Content Distribution Network (CDN) administrators to conduct system maintenance functions such as rebooting system devices, backing up, and restoring devices.
This chapter contains the following sections:
The System dialog box provides options for rebooting your device and reconfigure your system. (See Figure 4-1.) To reboot a CDN device:
Step 2 Make sure that the correct device is displayed in the Device Selector field. If it is not, choose the correct device in the list. General information about the selected device is displayed.
Step 3 To reboot the selected device, click System Reboot. It may take up to 10 minutes for your device to reboot.
Use the Reset option to reconfigure all of your Content Engines (CEs) with new CDM network settings in situations when the CDM has moved and its IP address has changed, or when the CDM hardware has been replaced.
To reconfigure a CDN device:
Step 2 Under the heading System Reconfiguration, click Reset. This posts the CDM's new IP address in the boot packages of all the CEs configured on your CDN.
Step 3 You must now reboot each of your CEs. Use the Device Selector to select the name of the first CE.
Step 4 Click System Reboot to reboot the CE. You are prompted to confirm your decision to reboot the device.
Step 5 Click OK.
Step 6 Repeat Step 4 and Step 5 for each CE on your CDN.
Once they have rebooted, verify that each of your CEs successfully comes back online by clicking Device Console and looking for a green circle in the Online column adjacent to each CE.
The CDM provides the capability for tape backup and restoration to protect against lost data and to provide service recovery.
We recommend that you do a backup before performing any software upgrades.
 |
Note You must be running an X server on your PC client to use the backup and restore utilities. |
To use the backup option:
The Backup/Restore dialog box appears. (See Figure 4-2.)
Step 2 Click Start Backup to backup CDM data: configuration settings, media, URLs, and database. You are prompted to confirm your decision to backup the device.
Step 3 Click OK.
An X-interface window with the backup utility appears.
Step 4 Follow the instructions included separately for the BRU backup utility.
To use the restore option:
The Backup/Restore dialog box appears. (See Figure 4-2.)
Step 2 Click Start Restore. You are prompted to confirm your decision to do a restore.
Step 3 Click OK.
An X-interface window with the restore utility appears.
|
Note The restore process overwrites any user data on the system. While the restore process is running, the CDN is unavailable. |
Step 4 Follow the instructions included separately for the BRU restore utility.
You can view system error messages from the System Log dialog box. (See Figure 4-3.) If you perform an operation that fails, a file import for example, a message appears in the system log explaining why the import failed.
Once viewed, messages can be removed from the system log.
To view and remove system log error messages:
The system-generated error messages are displayed.
Step 2 Select the check box next to error messages that you want to remove from the system log. Select All to choose all of the files or None to clear your selections.
Step 3 Click Remove.
The two supported methods for updating your CDN software are:
Updates of the CDN software are available from CCO, the Cisco customer support portal. Once you have downloaded the appropriate software from CCO, use the manual upgrade procedure described in the "Performing a Manual CDN Software Upgrade" section to distribute the update files to all your CDN devices.
|
Note In order to access CCO and download your CDN software update, you need a registered username and password for the site. If you are a Cisco customer and service contract owner, a Cisco reseller, Premier Certified Partner, the customer of a Cisco certified Partner Initiated Customer Access (PICA) partner, or a Cisco consultant, you can acquire a CCO login from the Cisco web site. |
CDN software can be downloaded from CCO using either a browser pointed to the CCO web site, or an FTP application connected to the Cisco FTP site. Use the appropriate directions that follow to connect to CCO.
To connect to the CCO web site:
Step 2 Log in to Cisco CCO:
|
Note You need to have a service contract number, CCO registration number and verification key, PICA registration number and verification key, or packaged service registration number in order to complete the online CCO registration process. |
Step 3 Within CCO, locate the Service & Support section and click the Software Center link.
Step 4 From the Software Center page, locate the area in which the CDN software upgrade has been placed.
|
Note If you cannot locate the CDN Software in any of the areas of the Software Center, scroll to the bottom of the Software Center page and click the Products link under the heading Other Sections. When the Products page appears, click Products Home Page. Use the index of Cisco products available on the Products Home Page to help you locate the Content Distribution Network (CDN) support page. |
Step 5 Follow the links for downloading your CDN update files.
Step 6 In the download area, locate the version of the CDN software that you need and click on the file name to initiate download.
Step 7 If you are prompted to open the file or save it to a disk, choose Save to save the file to a disk. Locate a directory on your hard drive or LAN to temporarily hold the upgrade file and click OK.
|
Note You will later import this file to the CDN, so be sure to place it in a location that makes it easy to retrieve for import later. |
Step 8 Proceed to the "Performing a Manual CDN Software Upgrade" section for instructions on using the upgrade file to upgrade the software on your CDN devices.
In addition to downloading software upgrades for the CDN product from the Cisco CCO web site, you can also use your web browser to download CDN software from Cisco's designated FTP site, ftp://ftp.cisco.com.
Step 2 Log in to Cisco's FTP server as a registered user or as a guest.
ftp://userid:password@ftp.cisco.com
ftp://ftp.cisco.com
ftp://access_code:userid@host.domain/coded
Step 3 Browse the directory tree until you locate the directory containing the CDN software upgrade files, for example:
ftp://userid:password@ftp.cisco.com/cisco/internet/CDN/
|
Note Guest users will only be able to see images that are located under the /pub directory. |
Step 4 Upload the upgrade file to your local machine.
If you are prompted to open the file or save it to a disk, choose to save the file to a disk. Locate a directory on your hard drive or LAN to temporarily hold the upgrade file and click OK.
|
Note You will later import this file to the CDN, so be sure to place it in a location that makes it easy to retrieve for import later. |
Step 5 Proceed to the "Performing a Manual CDN Software Upgrade" section for instructions on using the upgrade file to upgrade the software on your CDN devices.
In order to manually upgrade your CDN, you must:
1. Create a manual upgrade channel that will distribute the updated license.
2. Subscribe any CDN devices requiring a software update to the manual upgrade channel.
3. Import software update files to the manual upgrade channel.
4. Distribute software update files to all devices marked for upgrade.
Once these steps are complete, you can use the Software Update feature to install the software upgrade files to subscribed devices. Refer to the sections below for more details on completing each step.
To create a manual upgrade channel:
Step 2 Log on using your administrator logon.
Step 3 From the Channels menu, click Channel Console.
Step 4 Click Add Channel.
Step 5 Select the check box next to the channel name Channel # and click Edit.
|
Note "Channel #" is the default channel name. If you have added other channels and have not renamed them, the channel that you added will be named "Channel #" (# being the next incremental number). |
Step 6 In the Name field, change the name of the channel to MANUAL_UPGRADE. The channel must use this name (and letter case, as well) in order for it to function as an upgrade channel.
Step 7 In the Size Limit field, enter a value that will accommodate your upgrade files. For example, entering 100 in the field provided and then clicking the MB button sets the size limit of the MANUAL_UPGRADE channel to 100 MB.
Step 8 Select both the Auto Subscribe and Auto Replicate check boxes.
Step 9 Click Save Changes.
Once you have created your upgrade channel, subscribe all the devices requiring a software update to that channel.
Step 2 From the Channel Selector, choose the MANUAL_UPGRADE channel.
Step 3 In the Unsubscribed CEs column, click All to select all of the unsubscribed devices for subscription to the upgrade channel.
Step 4 Click Subscribe. The selected CEs will be subscribed to the MANUAL_UPGRADE channel and will receive upgrade files once they are imported to the channel.
To import the software update files to the manual upgrade channel:
Step 2 From the Channels menu, click Import Progress to monitor the progress of your import.
When the import is finished, the import status will be "complete."
Step 3 Once you have imported your software upgrade to the manual upgrade channel, see the "Updating Software Using the CDM Software Update Feature" section to complete the upgrade process.
From the Software Update dialog box, you can update the system software. To update the system software:
Step 2 Under the heading Available Version, click the appropriate version available for upgrade. If there is only one upgrade available, a check box is not displayed. The upgrade is selected automatically.
Step 3 Under the heading Devices Available for Upgrade, select the check box for each available device that you want to upgrade.
Step 4 Click Start Update. The selected devices reboot when the upgrade is finished.
The Cisco CDN is made up of a number of different hardware and software components, some of which require separate licensing. Periodically, you may need to expand or update license information for one or more of the CDN's components, for example, RealServer.
To facilitate licensing upgrades for the components of the CDN, Cisco has developed a procedure that uses the CDN to make the distribution of license upgrade files seamless and centrally organized. Using a specially designated CDN channel, you can initiate license upgrades for certain CDN components from the CDM to any subscribed CEs.
In order to use the license distribution feature you must first do the following:
1. Obtain license update files from Cisco. These files typically are installed on your CDN hardware and shipped with your CDN product.
2. Create a license distribution channel on your CDM.
3. Subscribe any CEs requiring license upgrades to your license distribution channel.
4. Import a license update file to your license distribution channel.
5. Replicate the license update file to subscribed CEs, automatically initiating the license upgrade process on each CE.
Refer to the sections that follow for instructions on completing each of these steps.
Software license update files will be distributed to you from Cisco on your CE and CDM hardware.
The directory provided to store license update files on your CDM and CE machines is \Sonoma\State\Real\License.
All license update materials will be placed in this location during the manufacturing process. Update files should not be moved from this location because the CDN license update feature looks specifically to the \Sonoma\State\Real\License directory on the CDM and CEs when it is activated.
The first step in distributing license updates to your CDN devices is to create a channel through which licenses will be distributed.
To create a license distribution channel:
The Channel Console dialog box appears.
Step 2 Click Add Channel.
A new channel with the default name "Channel#" is added to the Channel Console list, where # is a sequential number assigned to the CDM.
Step 3 Click Edit for the newly created channel. Using the options provided, rename your channel accordingly. For example,
License Distribution Channel
|
Note Unlike the MANUAL_UPGRADE channel, there are no requirements for the name of the license distribution channel. |
A description for the channel is optional.
Step 4 Verify that the Auto Subscribe and Auto Replicate options are not selected. You will be distributing license updates to selected CEs at specified times, so you do not want these features enabled.
Step 5 Activate the license distribution feature by selecting the Is License.
Step 6 Click Save Changes.
Once you have created your license distribution channel, you are ready to begin updating your CDM and CEs with updated license information. In order to do this, however, you must first prepare the channel to distribute licenses by completing the following tasks.
In order for designated devices to receive the update license command, they must be subscribed to the license distribution channel. When subscribed devices receive the replicated "trigger" file from the license update channel, they activate an update script stored locally in the \Sonoma\State\Real\License directory.
To subscribe devices to your license distribution channel, follow the steps in the "Subscribing a Content Engine to a Channel" section.
The license update process for a device is triggered by the replication of a file from a designated license distribution channel. This file replication creates a link in the CDN system to stored license update files and starts the update process.
Any file can serve as a trigger file for the software update, providing it can be safely imported to the CDN system and replicated to subscribed devices. Although many software updates come with "license key" files containing information on enabled and disabled features particular to your installation and your license agreement, such files do not need to serve as the trigger file for your update through the CDN product.
Regardless of its name or format, you need to import the license update trigger file to the channel you designated as your license distribution channel before the license update process can begin. Follow the instructions in the "Importing Media" section to successfully import the trigger file to your license distribution channel.
Once you have imported the license update "trigger" file to your license distribution channel and have subscribed all devices for which you wish to update software licenses, you are ready to begin the update process.
To initiate a software license update for your subscribed CDN devices:
The Media Editor dialog box appears. (See Figure 3-6.)
Step 2 Make sure that the designated license distribution channel name is displayed in the drop-down list on the left side of the dialog box. If it is not, click to expand the list and select the license distribution channel.
Step 3 Click the thumbnail image for the license update "trigger" file you imported to the channel to edit its properties.
Fields displaying the media file properties appear.
Step 4 Select the Replicate check box.
Step 5 Click Save Changes.
Clicking Cancel Changes returns all values to their previous settings when you last clicked Save Changes.
The selected file is replicated to all CEs subscribed to the license update channel, initiating the license update process.
