Deleting a Device
Deleting a Device
You can delete a device if the device is experiencing unresolvable problems or when its network address
or configuration has changed and you need to add the device back to the CDS network using its new
address and configuration information.
Caution If you delete the only SR in your CDS network, you are removing the ability of your CDS network to
fill user requests.
When you delete an SE from the CDS network, you are removing that device and the content it contains
from the routing scheme that the CDS uses to fill user requests. Although the CDS routes
requests around SEs that are busy, offline, or missing, removing an SE may affect the speed at which the
CDS network can serve user requests.
Note You cannot delete an SE if it is the only device assigned to a location that is designated as the root
location (Content Acquirer) for a delivery service and there are other SEs associated with the delivery
service. You can delete the Content Acquirer for a delivery service if the Content Acquirer is the only
SE associated with that delivery service. However, deleting the only SE in a delivery service makes the
delivery service unable to deliver content. If you receive an error message referencing the Content
Acquirer for a delivery service, add more SEs to that location, or change the root location by choosing
an SE in a different location to be the Content Acquirer for the delivery service before attempting to
delete the SE again.
Removing the device from the CDS network involves using the CLI to shut down CDS network services
and deregister the node. If you are removing the device because of hardware failure and it cannot be
accessed through its CLI, you can remove the device by using the CDSM; however, the device continues
to store its registration information until you deregister it by using the CLI.
Before a device can be removed from the CDS network, the following conditions must be met:
• The device must have been activated in the CDSM.
• The CDSM must be operating.
• The device must have the correct CDSM IP address or hostname configured.
• The CDSM IP address or hostname must be that of the primary CDSM.
Deleting a device from the CDS network involves using the CLI to remove the registration information
from the device itself and removing the registration record from the CDSM.
Note Do not use the CDSM to delete a device while the device is still active and registered. The CDSM delete
feature removes only the device’s registration record from the CDSM; it does not deregister the device.
The device retains its registration information and continues to contact the CDSM; however, the CDSM
no longer recognizes the device.
If for some reason the CDSM loses the registration record of a device, use the cms deregister force
command on the device to remove all of its registration information. Then use the cms enable command
to reregister the device with the CDSM as though it were a new node in the CDS network.
To remove and deregister a device, do the following:
Step 1 Open an SSH session to the device CLI.
