•Recovering a Lost Password for the ACNS Software E-CDN Application

•Recovering from Missing Disk-Based Software

Recovering the System Software

The Content Engine, Content Router, and Content Distribution Manager have a resident rescue system image that is invoked should the image in Flash memory be corrupted. A corrupted system image can result from a power failure that occurs while a system image is being written to Flash memory. The rescue image can download a system image to the main memory of the device and write it to Flash memory.

To install a new system image using the rescue image, perform the following steps:

Step 1 Download the system image file (*.sysimg) to a host that is running an FTP server.

Step 2 Establish a console connection to the device and open a terminal session.

Step 3 Reboot the device by toggling the power on/off switch.

The rescue image dialog appears. The following example demonstrates how to interact with the rescue dialog (user input is denoted by entries in bold typeface):
This is the rescue image. The purpose of this software is to let
you download and install a new system image onto your system's
boot flash device. This software has been invoked either manually
(if you entered `***' to the bootloader prompt) or has been
invoked by the bootloader if it discovered that your system image
in flash had been corrupted.
To download an image, this software will request the following
information from you:
    - which network interface to use
    - IP address and netmask for the selected interface
    - default gateway IP address
    - server IP address
    - which protocol to use to connect to server
    - username/password (if applicable)
    - path to system image on server
Please enter an interface from the following list:
    0: FastEthernet 0/0
    1: FastEthernet 0/1
    0
Using interface FastEthernet 0/0
Please enter the local IP address to use for this interface:
[Enter IP Address]: 172.16.22.22
Please enter the netmask for this interface:
[Enter Netmask]: 255.255.255.224
Please enter the IP address for the default gateway:
[Enter Gateway IP Address]: 172.16.22.1
Please enter the IP address for the FTP server where you wish
to obtain the new system image:
[Enter Server IP Address]: 172.16.10.10
Please enter your username on the FTP server (or 'anonymous'):
[Enter Username on server (e.g. anonymous)]: anonymous
Please enter the password for username 'anonymous' on FTP server (an 
email address): 
Please enter the directory containing the image file on the FTP 
server:
[Enter Directory on server (e.g. /)]: /
Please enter the file name of the system image file on the FTP server:

Recovering a Lost Password for the ACNS Software Cache Application

If you are using the Cache application, and an administrator password is forgotten, lost, or misconfigured, perform the following steps to reset the password on the device.

Note There is no way to restore a lost password. You must reset the password to a new one, as described in this procedure.

Step 1 Establish a console connection to the device and open a terminal session.

Step 2 Reboot the device. While the device is rebooting, watch for the following prompt and press Enter when you see it:
Cisco ACNS boot:hit RETURN to set boot flags:0009
Step 3 When prompted to enter bootflags, enter this value:
0x8000
For example:
Available boot flags (enter the sum of the desired flags):
0x4000 - bypass nvram config
0x8000 - disable login security
[CE boot - enter bootflags]:0x8000
You have entered boot flags = 0x8000
Boot with these flags? [yes]:yes
[Display output omitted]
Step 4 When the device completes the boot sequence, you are prompted to enter the username to access the CLI. Enter the default administrator username (admin):
Cisco Content Engine Console
Username: admin
Setting the configuration flags to 0x8000 lets you into the system, 
bypassing all security. Setting the configuration flags field to 
0x4000 lets you bypass the NVRAM configuration.
Step 5 Once you see the CLI prompt, set the password for the user using the username name password command in global configuration mode.

Step 6 Use the write command to save the configuration change.

Step 7 Reboot your device.

In ACNS software, the bootflags are reset to 0x0 on every reboot.

Recovering a Lost Password for the ACNS Software E-CDN Application

If the E-CDN application is enabled and the administrator password is forgotten, lost, or misconfigured, perform the following steps to reset the password on the Content Distribution Manager. Once the password is reset on the Content Distribution Manager, these changes propagate out to any Content Router or Content Engine devices that are managed by the Content Distribution Manager.

Note There is no way to restore a lost password. You must reset the password to a new one, as described in this procedure.

Step 1 Establish a console connection to the Content Distribution Manager and open a terminal session.

Step 2 Reboot the device. While the device is rebooting, watch for the following prompt and press Enter when you see it:
Cisco ACNS boot:hit RETURN to set boot flags:0009
Step 3 When prompted to enter bootflags, enter this value:
0x8000
For example:
Available boot flags (enter the sum of the desired flags):
0x4000 - bypass nvram config
0x8000 - disable login security
[ACNS boot - enter bootflags]:0x8000
You have entered boot flags = 0x8000
Boot with these flags? [yes]:yes
[Display output omitted]
Step 4 When the device completes the boot sequence, you are prompted to enter the username to access the CLI. Enter the default administrator username (admin):
Cisco Content Engine Console
Username: admin
cdm# 
Setting the configuration flags to 0x8000 lets you into the system, 
bypassing all security. Setting the configuration flags field to 
0x4000 lets you bypass the NVRAM configuration.
Step 5 Once you see the CLI prompt, wait several minutes to allow the E-CDN application to start completely (check the output of the show ecdn command and look for "ECDN content distribution manager is running"). Then reset the administrator password to its default value ("default") by running the ecdn reset-cdm-gui-password command in global configuration mode.
cdm(config)# ecdn reset-cdm-gui-password
Step 6 Use the write command to save the configuration change.

Step 7 Reboot the Content Distribution Manager.

In ACNS software, the bootflags are reset to 0x0 on every reboot.

Step 8 After the Content Distribution Manager has rebooted, the administrator password can be changed to a nondefault value using the Content Distribution Manager GUI.

Recovering from Missing Disk-Based Software

This section describes the recovery procedures to use, if for some reason the software installation on the first disk drive (disk00) is corrupt or missing.

This situation is most likely to occur only if you replaced disk00 in your Content Engine, Content Router, or Content Distribution Manager. By design, the software installation on disk00 cannot be corrupted by a system crash or a power failure.

Using the Software Recovery Shell in ACNS 4.0 and ACNS 4.1 Software

This section describes the software recovery shell feature. Use this feature if the ACNS 4.0 or 4.1 software detects that the software installation on the first disk drive (disk00) is corrupt or missing.

Note For information on the physical location of the disks and how to remove and replace a disk drive (for the seven-rack unit chassis models), refer to the hardware installation guide that shipped with your system.

After you replace disk00 and power up your system, the following error message appears:
There appears to be an incomplete or problematic software
installation on your first disk drive. This may be due to
older software having previously been installed on your system.
Alternatively, if you have just replaced the first disk drive,
software will have to be installed onto it.
Try getting on to network from saved parameters...
get-on-net-pp:got pp_signature!= 0xcfcfcfcf (0x0), bailing
no pp
Looking for network configuration from saved CLI config...
Done get to net
done
Manual intervention required to download new software!
If your network configuration was retrieved and applied successfully,
then you can telnet in and interact with the software-recovery shell.
Alternatively, you can run software-recovery shell on console right 
now.
If you are reading this right now, you should probably enter 'yes' 
below unless you plan to telnet to the box.
If the FTP download fails for any reason, the whole process is repeated. When the device has booted to the point that the above message appears, and assuming that you have previously saved network parameters, you can use Telnet to access the device at this point and interact with the software-recovery shell.

The other option is to run the software-recovery shell directly on the console by typing yes at the initial prompt, as follows:
Run software-recovery-shell on console? Enter yes if desired:yes
After you have entered the software-recovery shell, the following dialog appears. (In this example, administrator entries are shown in bold type.)
This is config-shell
It appears that ACNS 4.x software is not properly installed on your
first disk drive (disk00).  [/sw and/or /swstore not mounted]
You have several options:
  - You can continue booting.  This will require that disk00
    be erased and reformatted and that a full ACNS 4.1 release image
    be downloaded and installed to disk00.  This is probably what
    you should do, unless you specifically know otherwise.
  - You can reboot and invoke the rescue image, if you know what
    you are doing.
  What would you like to do [continue or reboot]: continue
Please confirm.  disk00 will be reformatted!
  Confirm [continue, reboot]: continue

Using the Command-Line Interface in ACNS 4.2 Software

This section explains how to recover from missing disk-based software or a failed system disk when you are using ACNS 4.2 software. In earlier versions of ACNS software, a feature called the software recovery shell was used to recover from missing disk-based software. A new procedure that uses the CLI has been implemented in the ACNS 4.2 software release.

If the system disk (disk00) fails or is missing, ACNS 4.2 software continues to run; however, it runs in a degraded mode in which HTTP proxy and related HTTP features still work, but most other features fail.

To recover from this condition, follow these steps:

Step 1 Power down the device and replace the failed or missing disk00 with a new, blank disk.

Step 2 After the new disk is installed, power up the device.

Step 3 From a console or through a Telnet session, check the startup messages that appear on your screen.

If there is a problem with disk00 or the disk-based software, a message similar to the following appears:
*****
Your first disk is not in standard configuration.
You might need to run 'disk recover' from the CLI.
*****
Step 4 Log in as admin.

In earlier versions of ACNS software, a feature called the software recovery shell was used to recover from missing disk-based software. A new procedure that uses the CLI has been implemented in the ACNS 4.2 software release. If the system disk (disk00) fails or is missing, ACNS 4.2 software continues to run; however, it runs in a degraded mode in which HTTP proxy and related HTTP features still work, but most other features fail. To recover from this condition, follow these steps: Step 1 Power down the device and replace the failed or missing disk00 with a new, blank disk. Step 2 After the new disk is installed, power up the device. Step 3 From a console or through a Telnet session, check the startup messages that appear on your screen. If there is a problem with disk00 or the disk-based software, a message similar to the following appears: * Your first disk is not in standard configuration. You might need to run 'disk recover' from the CLI. * Step 4 Log in as admin. Cisco Content Engine Console Username: admin Password: System Initialization Finished. ce-507 con now available Press RETURN to get started! Step 5 Enter the disk recover command to create the file systems on disk00 that are for internal system use. ce-507# disk recover This will erase everything on disk00. Are you sure? [no]yes System filesystems appear to have been installed. Please verify your software installation with 'show flash' and install a new image if necessary. ce-507# ce-507# show flash /diamond/bin/exec_show_flash: could not open /swstore/manifest: No such file or directory Your software installation is damaged. Please run 'copy ftp install' to install a new image. Step 6 Enter the copy ftp install command to download and install a new system image.
