Restore SightPath Studio Data on Cisco CDM Hardware
Verify Media Transfer on the Cisco CDM
Obtaining Technical Assistance
The SightPath migration program was created with the dual goal of replacing legacy SightPath hardware and software with the latest Cisco CDN hardware, while simultaneously protecting the technology investment of our SightPath customers.
Using the migration procedures in this document, you will back up your existing SightPath Studio channels and media, activate your new Cisco Content Distribution Manager (CDM) 4600 series hardware, then move your data and media files to the new CDM. Once your data has been migrated to the CDM, the device is activated and existing Content Engines (formerly SightPath Appliances) are pointed to the new CDM and can begin receiving and distributing media.
Following migration, you will have a CDM that uses proven, rack-mounted Cisco hardware. This allows you to easily integrate future CDN software releases and take advantage of next-generation Web services. Following CDM migration, SightPath A200 or A230 Appliances can be replaced with Cisco CEs when it is convenient.
The following table presents the recommended hardware migration path for SightPath Studios.
| Legacy SightPath Hardware | New Cisco Hardware | Migration Notes |
|---|---|---|
SightPath S1000 Studio | Cisco CDM 4630 | Do not attempt to backup or restore data. Manually re-create channels on the Cisco CDM 4630 and import media directly to the Cisco hardware. |
SightPath S2000 Studio | Cisco CDM 4650 | Follow the migration procedure outlined in this document, watching for instructions specific to the SightPath S2000 Studio. |
SightPath S4000 Studio | Cisco CDM 4650 | Follow the migration procedure outlined in this document, watching for instructions specific to the SightPath S4000 Studio. |
The SightPath migration program is offered to SightPath customers who meet the following conditions:
This section describes the process of migrating SightPath Studio hardware and software to the Cisco CDM 4600 series platform.
Use the following steps to migrate your SightPath hardware to the Cisco CDN platform:
2. Back Up SightPath Studio Data
3. Activate Cisco CDM Hardware
See the sections that follow for detailed instructions on completing each of these steps.
During the migration process, you transfer data from a legacy SightPath Studio to a Cisco 4600 series CDM.
Before starting your backup, you need to prepare the SightPath Studio to back up its data, and the Cisco CDM to receive the backed up data from the Studio.
Complete the following steps before attempting to back up and restore your data.
Your SightPath Studio must be running at least version 2.1 of the CDN Enterprise software in order for your data to be successfully transferred to the Cisco CDM hardware.
If you are using a version of the CDN Enterprise software other than version 2.1, refer to the "Installation Notes" section of the Release Notes for the Cisco CDN Software Enterprise Edition Version 2.1 for instructions on acquiring an upgrade to version 2.1 from Cisco.
You need to have a Quantum DLT 7000 tape backup device attached to your SightPath Studio during backup.
Refer to Chapter 3, "Working with the Content Delivery Network" in the Cisco CDN Software Enterprise Solution Users Guide for instructions on creating content channels on your CDM and importing media to them. Alternatively, you can contact Cisco Technical Support if you have questions. See the "Obtaining Technical Assistance" section for details on obtaining technical assistance from Cisco Systems.
 |
Note If you are using a SightPath S1000 Studio, you will not be able to migrate directly from your Studio to the Cisco CDM hardware. Instead, you will need to recreate your data on the Cisco CDM by manually building your content channels and importing your media files directly to the CDM. |
If you have only one Quantum DLT 7000 tape drive, attach it first to the SightPath Studio and perform your backup, then attach the device to the CDM and use it to restore data on the CDM.
To attach the Quantum DLT 7000 tape drive to the SightPath S2000 or S4000 Studio:
Step 1 If you are backing up a SightPath S2000 Studio, proceed to Step 2.
If you are backing up a SightPath S4000 Studio, disconnect the internal DAT drive before attempting to attach the external Quantum DLT 7000 tape drive.
You can disconnect the internal DAT drive by removing the cover from your S4000 Studio, locating the DAT drive, and disconnecting the SCSI connector cable where it attaches to the internal SCSI card in the S4000.
 |
Warning Contact Cisco Technical Support if you are not sure of the proper procedure for removing the cover from your S4000 hardware and removing or replacing any of the hardware used by your S4000, including the internal DAT drive. See the "Obtaining Technical Assistance" section for instructions on contacting Technical Support. |
Step 2 Use the SCSI connector cable to attach the Quantum DLT 7000 tape drive to the SCSI port located on the back of the SightPath Studio. Make sure that both ends of the cable are properly seated in their ports before continuing.
Step 3 Place a blank Quantum DLT Type IV backup cartridge in the DLT 7000 device.
Step 4 Power on the DLT 7000 tape drive and reboot the Studio.
The Studio recognizes the DLT 7000 tape drive, and you should hear the blank tape spooling in the tape drive.
Step 5 Proceed to the "Back Up SightPath Studio Data" section to initiate the backup once your tape drive is attached.
Before attempting to upgrade your SightPath Studio hardware and software to the Cisco CDM 4600 series, you must first back up the current SightPath Studio. Make sure you have prepared your SightPath Studio for backup by attaching a Quantum DLT 7000 tape drive to the Studio. See the instructions in the "Attach Backup Device" section for details on attaching the DLT 7000 tape drive.
To perform your SightPath Studio backup, you need a PC workstation that is located on the same subnet as your SightPath Studio and has the following software installed:
To back up your SightPath S2000 Studio data:
Step 1 Perform a full backup of your SightPath S2000 Studio data using the Quantum DLT 7000 tape drive. This full backup is for emergency restore purposes, and should be contained on a separate DLT backup tape from that used to migrate data to your CDM device.
Follow the instructions in the "Backing Up the SightPath S4000 Studio" section to perform a full backup of your S2000 Studio prior to completing this procedure.
Step 2 Once your emergency backup of the S2000 Studio is complete, launch a Telnet session and connect to your SightPath S2000 Studio from a PC workstation.
If you receive the following error message, you need to enable Telnet on the Studio.
connection to host lost
Enable Telnet using the following procedure:
a. Point your browser to the "box links" area of your CDM. For example:
http:// <Studio_2000_IP_address>/cgi/box
b. If prompted, log on using your administrator account.
c. Click Feature.
d. From the Features interface, select Enable Telnet until next reboot [telnet].
Step 3 Click Set and then close the browser window.
Step 4 Once you have established a telnet connection to the S2000 Studio, log on to the Studio using the root account. For example:
login: root
password: default
Step 5 Copy the contents of the sonoma/state1/cache directory to sonoma/state/cache. For example:
cp /sonoma/state1/cache/* sonoma/state/cache
Step 6 Remove the duplicate files from the directory you copied. For example:
rm /sonoma/state1/cache/*
You are now ready to perform a backup of your S2000 Studio data. From this point forward, the procedure for backing up data is identical to that used for the S4000 Studio.
Step 7 Proceed to the "Backing Up the SightPath S4000 Studio" section to complete backup of your S2000 Studio.
To back up your SightPath S4000 Studio data:
Step 1 From the PC workstation, launch your X-Windows terminal emulator (hereafter referred to as the X client).
Step 2 Launch your Web browser and enter the IP address or DNS name of the SightPath Studio in the field provided for entering the Web site URL.
Step 3 Press the Enter key.
The Studio login dialog box appears.
Step 4 Enter your administrative username and password to log in to the Studio.
Step 5 Click Backup/Restore.
The Backup/Restore dialog box appears.
Step 6 Under the heading System Backup, click Start Backup.
You are prompted to confirm your decision to initiate a backup.
Step 7 Click OK.
A message indicating that the tape backup utility user interface is being launched appears in the CDM interface. Your X client window now displays the Backup Restore Utility (BRU) interface. (See Figure 1.)
Step 8 Switch from the CDM to the X client displaying the BRU interface.
|
Note The SightPath Studio is unable to serve media to users from this point forward. |
Step 9 In BRU, click Full.
The Device Stats dialog box appears, providing details on the functioning of the tape backup device.
Step 10 Click OK to continue.
The Enter Archive Label dialog box appears.
Step 11 In the field provided, enter a name for your backup volume, and then click Create Backup.
The Archive Requirements dialog box appears while BRU calculates the number of backup tapes required to back up all your Studio data.
Step 12 When the Archive Requirements dialog box displays an "Estimate Done" message, note the number of 40- or 80- GB tapes required in the Volumes Req'd field.
Step 13 Click Continue.
The Backup Progress Display dialog box appears, showing the progress of the Studio data backup and displaying a status message for each stage in the status bar on the BRU dialog box. (See Figure 2.) The two stages of the backup process are:
Step 14 When the display indicates the backup process is complete, click Unload.
Step 15 Wait a few moments and remove your backup tape from the Quantum DLT 7000 tape drive. Properly label and store your backup tape. You will need it to activate your Cisco CDM.
Step 16 Proceed to the "Restore SightPath Studio Data on Cisco CDM Hardware" section.
Once you have successfully backed up your SightPath Studio, shut down the device and physically disconnect it from your LAN. Proceed to the next step, activating the Cisco CDM.
Before attempting to activate your Cisco CDM, make sure that you meet the following criteria:
To activate your CDM:
Step 1 Refer to the section on activating the Content Distribution Manager in Chapter 2, "Configuring and Activating Content Delivery Network Devices" in the Cisco CDN Software Enterprise Solution Configuration Guide.
Step 2 Once the CDM has booted successfully, use your X client to connect to the CDM and log in using your administrative username and password.
Step 3 Navigate to the following directory:
/sonoma/state
Step 4 Once in the proper directory, use the -f log command to view the end of the CDM error log, showing any errors that may have occurred when booting your CDM. For example:
tail -f log
Step 5 Verify that errors were not reported in the CDM error log. If errors were logged, see the "Obtaining Technical Assistance" section.
Step 6 Verify that the CDM is accessible by returning to your PC desktop and pointing your Web browser to the CDM by typing the CDM IP address or DNS name in the field provided for entering the Web site URL.
Once you have activated the CDM, you are ready to restore your SightPath Studio data, completing the upgrade process.
You need to have a Quantum DLT 7000 tape backup device attached to your Cisco CDM when you restore your Studio data to the CDM.
|
Note Your CDM must be rebooted subsequent to attaching the Quantum DLT 7000 tape drive, and before attempting to transfer your Studio data to the CDM. |
Refer to the instructions that follow for information on attaching the Quantum DLT 7000 tape drive to your CDM.
If you have only one DLT 7000 tape drive, attach it first to the SightPath Studio and perform your backup, then attach the device to the CDM and use it to restore data to the CDM.
To attach the Quantum DLT 7000 tape drive to the Cisco Content Distribution Manager 4630:
Step 1 Use a SCSI connection cable to attach the Quantum DLT 7000 tape drive to the SCSI port located on the back of your Cisco Content Distribution Manager 4630 device. Make sure that both ends of the cable are properly mounted in their ports before continuing.
Step 2 Place the DLT Type IV backup cartridge with your Studio backup on it into the Quantum DLT 7000 tape drive.
Step 3 Power on your Quantum DLT 7000 tape drive and reboot the CDM.
The CDM recognizes the DLT 7000 tape drive, and you should hear the blank tape spooling in the drive.
Step 4 Proceed to the "Restore SightPath Studio Data on Cisco CDM Hardware" section.
The Cisco 4650 Content Distribution Manager comes with a factory-installed DLT 7000 tape drive, so no attachment to an external tape drive is required. You will, however, require an external DLT 7000 tape drive to attach to your SightPath Studio and back up your Studio data.
To prepare your Content Distribution Manager 4650 to accept SightPath Studio data:
Step 1 Locate the Quantum DLT 7000 tape drive on your CDM.
Step 2 Open the tape drive door and place the DLT Type IV backup cartridge with your Studio backup on it into the tape drive.
Step 3 Proceed to the "Restore SightPath Studio Data on Cisco CDM Hardware" section.
Once you have backed up your SightPath S2000 or S4000 Studio, activated your Content Distribution Manager 4630 or 4650 hardware, and successfully booted the CDM, you need to prepare it to receive the data copied from your SightPath device.
To restore data on your new Cisco CDM:
Step 1 Return to the PC workstation and launch the X client.
Step 2 From your PC, launch your Web browser and point it to your CDM by entering the IP address or DNS name of your CDM in the field provided for the Web page URL.
Step 3 In the CDM user interface, click Backup/Restore.
The Backup/Restore dialog box appears.
Step 4 Under the heading System Restore, click Start Restore.
You are prompted to confirm your decision to restore data to the CDM.
Step 5 Click OK.
A message indicating that the tape backup utility user interface is being launched appears in the CDM user interface. Your X client window now displays the Backup Restore Utility (BRU) user interface.
Step 6 Switch from the CDM to the X client displaying the BRU user interface.
Step 7 Select the restore option (the icon depicting a tape-to-disk transfer) or click File > Restore.
The Device Stats dialog box appears, providing you with the status of the Quantum DLT 7000 tape drive.
Step 8 Click OK and wait while BRU retrieves a list of the files on the backup tape.
BRU displays the contents of the backup tape. (See Figure 3.)
Click Add All to select all the files on the backup tape for transfer to the CDM.
The filenames appear in the right half of the BRU dialog box.
Step 9 When the status indicator at the bottom of BRU reads "ready," click Restore. The BRU Restore dialog box appears, showing you the progress of your data transfer. Depending upon the amount of data you are restoring, this transfer could take between ten and thirty minutes.
Step 10 When the restore completes, the following message appears:
Warning: BRU Exited abnormally.
This message is expected, and does not mean your data has not been restored on the CDM.
Step 11 Click Cancel to close the error message.
The BRU Execution Log dialog appears with these error messages:
Can't access for write...Read-only file system.
Ignore the messages. They are expected.
Step 12 Click Close to close the BRU Execution Log.
Step 13 Click File > Exit, or the open door button to close BRU.
The BRU application closes and the CDM reboots.
Once the CDM has completed rebooting, verify that your CDM data has been successfully transferred from the SightPath Studio to the Cisco CDM.
Once you have transferred data from your SightPath Studio to the CDM, you need to verify that your channel and media information was properly transferred between the two devices, and that the CDM is ready to begin replicating content out to Content Engines (CEs) on your CDN.
To verify that your backed up data has been successfully transferred to the CDM:
Step 1 From your Windows desktop, launch your Web browser and point it to your CDM by entering the IP address or DNS name of your CDM in the field provided for the Web page URL.
Step 2 Click Device Console. You should be able to see the other CEs on your CDN. (See Figure 4.) Verify that the CDM is not the only device listed on the Device Console.
If the CDM is the only device listed, from the Device Console, verify that the CDM is using the correct IP address.
Step 3 Click Channel Console. Verify that your channels and their content were accurately transferred to the Cisco CDM:
a. Click Previewer.
b. Click the first channel icon and verify that links to the media files in that channel appear.
c. Verify that a media file from each channel was successfully transferred to the Cisco CDM by clicking CDM Preview to play back the media file.
Step 4 If your channels and their content were successfully transferred to the CDM, but you were required to change the IP address of the CDM from that used by the SightPath Studio, you need to reconfigure each of your CEs to point to the new CDM IP address using the CDN Installation Wizard.
Refer to the instructions for configuring and activating content engines in Chapter 2, "Configuring and Activating Content Delivery Network Devices" of the Cisco CDN Software Enterprise Solution Configuration Guide, Version 2.1.
Step 5 Once your CEs are properly configured and recognize your CDM, the migration is complete. You can now invite users back on to the system.
If your channels or content did not transfer successfully, contact Cisco Technical Support.
If you are migrating from a SightPath S1000 Studio to the Cisco CDM 4630, you cannot use the backup and data transfer procedures described in this document.
Instead, you must manually recreate your Studio data on the Cisco CDM. To accomplish this, you must:
1. Catalog the name and contents of each channel on your Studio.
2. Make note of any user or administrative accounts on the Studio.
3. Locate copies of all media files you want to move to the Cisco CDM.
4. Activate your Cisco CDM 4630 using procedures documented in the Cisco CDN Enterprise Solution Configuration Guide Version 2.1.
5. Recreate the necessary user and administrative accounts on the Cisco CDM 4630 using procedures documented in the Cisco CDN Enterprise Solution User Guide Version 2.1.
6. Recreate your channels on the Cisco CDM 4630 using procedures documented in the Cisco CDN Enterprise Solution User Guide Version 2.1.
7. Reimport media files to your channels on the Cisco CDM 4630 using procedures documented in the Cisco CDN Enterprise Solution User Guide Version 2.1.
