Replacing a Device
Replacing a CDSM
To replace a CDSM in a CDS you must first add the new CDSM into the network as a standby CDSM.
For procedural information, see the “Configuring Primary and Standby CDSMs” section on page 3-8.
Note The primary and standby CDSMs must be running the same version of software. You must first add the
new CDSM with the same version as the existing CDSM. Once the standby CDSM has been added, you
must wait at least two polling intervals (10 minutes) for the databases to synchronize before you can
begin the upgrade procedure.
Note After you have activated the standby CDSM using the primary CDSM web interface and the device
shows as online in the Devices Table page, wait at least two polling intervals (10 minutes) before
changing roles to ensure that the standby CDSM has a record of the most recent configuration changes.
To promote the standby CDSM to primary, first stop the primary CDSM using the cdsm role standby
command. For procedural information, see the “Changing a Standby to a Primary CDSM” section on
page 3-9.
After the primary CDSM has been stopped, and the standby CDSM has taken the role of primary, wait
at least two polling intervals (10 minutes) before logging in to the new primary CDSM. The new primary
CDSM is accessible by entering the IP address of the CDSM with port 8443 in a web browser. For
example, if the IP address of your CDSM is 192.168.0.236, enter https://192.168.0.236:8443.
It is now safe to deactivate the old primary CDSM in the CDSM web interface and remove it from the
CDS network.
Note Do not try to take a back up of the old CDSM database and restore it on the new CDSM. This may lead
to problematic issues.
Replacing an SE or SR
Note If you replace a Content Acquirer with an SE that was not previously assigned to the delivery service,
all content is reacquired and old content is deleted.
Note To prevent the reacquisition of content when replacing a Content Acquirer, make one of the receiver SEs
in the same delivery service the replacement Content Acquirer. Add the new SE as a receiver SE, wait
until replication is complete for the newly added SE, and then designate it as the Content Acquirer.
When you replace a Content Acquirer in this manner, the SEs in the delivery service synchronize with
the new Content Acquirer through the metadata poll. Content is not redistributed to the other SEs in the
delivery service unless the content has changed since the last metadata poll.
To replace an SE or SR, do the following:
Step 1 Open an SSH session to the device being replaced.
