Software Upgrade
• While being upgraded, a node will be unavailable for a short time.
• All nodes, other than the node being upgraded, continue to operate at full capacity. The availability
of other nodes is not affected during an upgrade.
• Content is preserved during an upgrade or downgrade unless you remove a delivery service.
• All logs are preserved during an upgrade or downgrade, unless you change the disk configuration.
Anytime disk space is reconfigured, the logs are automatically removed.
We strongly recommend that you upgrade your CDS network devices in the following order:
1. Multicast sender Service Engines
2. Multicast receiver Service Engines
3. Non-Content Acquirer Service Engines
4. Content Acquirer Service Engines
5. Service Routers
6. Standby CDSMs (Upgrade before primary when using the GUI only.)
7. Primary CDSM
Note When you upgrade CDSMs using the CLI, we recommend that you upgrade your primary CDSM first,
and then upgrade your standby CDSM. Primary and standby CDSMs must be operating with exactly the
same software release as each other for failover to be successful.
Upgrading Software by Device Groups
Note This procedure is for Service Engines only. Service Routers and CDSMs cannot be associated with
device groups.
To upgrade your software on multiple Service Engines, do the following:
Step 1 Choose Devices > Device Groups. The Device Groups Table page is displayed.
Step 2 Click the Edit icon next to the name of the device group that you want to upgrade. The Device Group
page is displayed.
Step 3 From the left-panel menu, choose Software Update. The Software Update for Device Group page is
displayed.
Step 4 Choose the software file URL from the Software File URL list by clicking the radio button next to the
filename.
Step 5 Click Submit.
To view progress on an upgrade, go to the Devices Table page (Devices > Devices). Software upgrade
status messages are displayed in the Software Version column. These intermediate messages are also
written to the system log on the Service Engines. See Table 8-1 for a description of upgrade status
messages.
