Backup and Recovery Procedures
Recovering CDS Network Device Registration Information
Device registration information is stored both on the device itself and on the CDSM. If a device loses its
registration identity or needs to be replaced because of hardware failure, the CDS network administrator
can issue a CLI command to recover the lost information or, in the case of adding a new device, assume
the identity of the failed device.
To recover lost registration information, or to replace a failed node with a new one having the same
registration information, do the following:
Step 1 Mark the failed device as “Inactive” and “Replaceable” in the CDSM.
a. Choose Devices > Devices.
b. Click the Edit icon next to the name of the Service Engine you want to deactivate. The Device home
page is displayed.
c. From the left-panel menu, choose Device Activation.
d. Uncheck the Activate check box. The page refreshes, displaying a check box for marking the device
as replaceable.
e. Check the Replaceable check box and click Submit.
Note This check box only displays when the device is inactive.
Step 2 Configure a system device recovery key.
a. Choose System > Configuration.
b. Click the Edit icon next to the System.device.recovery.key property. The Modifying Config
Property page is displayed.
c. Enter a password in the Value field and click Submit. The default password is default.
Step 3 Configure the basic network settings for the new device.
Step 4 Open an SSH session to the device CLI and enter the cms recover identity keyword EXEC command,
where keyword is the device recovery key that you configured in the CDSM.
When the CDSM receives the recovery request from the Service Engine, it searches its database for the
Service Engine record that meets the following criteria:
• The record is inactive and replaceable.
• The record has the same hostname as given in the recovery request.
• The device is the same hardware model as the device in the existing record.
• The file system allocations for the device are the same as or greater than the device in the
existing record.
If the recovery request matches the Service Engine record, then the CDSM updates the existing record
and sends the requesting Service Engine a registration response. The replaceable state is cleared so that
no other device can assume the same identity. When the Service Engine receives its recovered
registration information, it writes it to file, initializes its database tables, and starts.
Step 5 Return to the CDSM and activate the device.
a. Choose Devices > Devices.
b. Click the Edit icon next to the name of the Service Engine you want to activate. The Device home
page is displayed.
